2024 Chevrolet Silverado EV

While exiting a highway via an off-ramp, the vehicle experienced a sudden mechanical failure consistent with internal engine/bearing failure. During deceleration on the off-ramp, the engine began to shudder violently and immediately lost power. The vehicle was unable to maintain normal operation and became unsafe in an active traffic environment. After coming to a stop, the engine would not restart and the vehicle was completely inoperable. There were no prior warning signs or alerts before the failure occurred. The issue developed abruptly while the vehicle was in motion. The vehicle required towing and dealer inspection. Diagnosis confirmed internal engine damage / bearing failure / engine seizure. The repair required engine replacement This failure is consistent with widely reported issues involving GM 6.2L V8 engines (model years 2019–2024) experiencing bearing failure and catastrophic engine damage. The same failure characteristics appear to be present in this vehicle. This represents a serious safety concern due to the sudden and complete loss of engine power and inability to restart the vehicle while in a traffic environment, creating risk of collision or roadway obstruction. The vehicle had approximately 65,000 miles at the time of failure.

Was driving the truck on the highway at 75mph when suddenly the motor revved up in rpm’s and vehicle lost all power. There was no warning lights or any limp mode or anything as such as far as warning. The truck lost all power and could hear metal to metal sounds and turned off the motor. I was able to coast the truck to an off ramp in 70mph traffic. The truck would not turn back on and vehicle was immobile, had to have the vehicle towed by a flatbed to a gm dealer near by. The dealer gave me a loaner pickup and hasn’t looked at my vehicle yet. I bought this pickup less then 3 weeks ago and the L87 recall and oil change had been done prior to me buying it. I was just happy that the truck didnt full shut down at that speed and cause a crash etc. Dealer said motor failure to me and couldn’t confirm a turn around time frame for my truck to get back to me.

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

My husband and I were driving his Chevy Silverado with our two dogs in the back. Without any warning or any alert, our vehicle came to a complete stop in the middle lane on a three lane highway. Not a slow stop where there was any time. I’m confirming immediate. At that time, the vehicle would not move at all for almost 5 minutes. As we sat there praying to God that we wouldn’t die as tractor trailers and other vehicles came flying past missing us by inches. It’s truly a miracle that no one was killed. He put truck in neutral and pressed start button and was not able to go any faster then 5 mph and once again a miracle we were able to make it to shoulder of highway without being hit. The vehicle was shaking excessively and flashing things like emissions, traction, as our videos and pictures will show when we made it to side of highway. This is a disgrace that any vehicle would ever be manufactured with this outcome. I am deeply grateful that my husband and I and our two dogs are alive and not injured but this should NEVER happen again.

On 1/20/26, we purchased a ‘24 Chevy Silverado EV from a Chevrolet dealership. 2 days later, on 1/22/26, while my husband was driving on the interstate, the tonneau cover partially detached and flew backwards lifting upwards and flapping violently. One of the metal crossbars detached completely from the tonneau cover and flew off the truck, and a second crossbar began to tear away. The cover was flapping forcefully which created a highly unstable and dangerous condition. My husband pulled over on the side of the interstate to remove the tonneau cover to prevent it from fully detaching. He placed the cover into the truck bed. This incident occurred suddenly, with no warning. This was a near-miss incident with potentially catastrophic consequences. If the tonneau cover had fully detached, it could have become airborne and struck another vehicle. The crossbar that flew off, could have struck another vehicle, easily penetrating a windshield, causing another driver to lose control, or result in a multi-vehicle collision. The risk of serious injury or fatality was significant. The next day, on 1/23/26, we took the truck and damaged tonneau cover to our local Chevrolet dealership for inspection. The service manager visually inspected the cover and documented the failure. We scheduled an appointment for repair at their soonest availability, 2/4/26. We will not feel comfortable using a new cover unless a modification is made to adequately secure the cover to prevent this from occurring again. We also called the Chevrolet dealership where we purchased the vehicle from and spoke with the general manager to let them know what happened, as they have sold close to 100 of these Chevy Silverado EV’s. They said this has happened to others and they speculate that GM is already aware of this concern. We urge the NHTSA and GM to take immediate action. Please open an investigation and issue a recall before someone is seriously injured or killed. Thank you NHTSA!

Email Subject I am reporting a serious safety-related defect involving sudden and complete vehicle shutdown while driving in a 2024 Chevrolet Silverado EV RST. Component/System Involved: The failure appears related to the 12-volt electrical system and associated vehicle control electronics. When the vehicle detects the 12V battery as dead or critically low, it immediately disables propulsion and control systems. The exact failed component is UNKNOWN. The vehicle is available for inspection upon request. Incident Description: This failure has occurred twice under similar conditions (ambient temperature approximately 25°F). On November 28, 2024 and again on January 2, 2026, after driving approximately two blocks at low residential speeds, the vehicle abruptly and completely shut down while in motion. In both incidents, the shutdown was immediate, without warning, and accompanied by a loud thud and an extremely abrupt stop. Safety Risk: In both incidents, the vehicle became completely immobilized in the roadway. I was unable to steer to the side of the road, restart the vehicle, or shift it into gear to move it out of traffic. This created a significant risk of collision. A similar failure at highway speeds could result in a severe or fatal crash. Warnings or Prior Symptoms: No warning lamps, messages, alerts, or other symptoms appeared prior to either shutdown. Problem Confirmation or Reproduction: The issue has occurred twice under cold-weather conditions. Inspections: After the first incident, the 12V battery was inspected and no issues were found. Following the second incident, the vehicle is currently being inspected at a Chevrolet dealership. No police or insurance inspections were performed. This behavior suggests the vehicle lacks a fail-safe or degraded-operation mode for 12V system failure and instead performs an immediate shutdown while in motion, which may represent a serious safety defect warranting investigation.

Vehicle: 2024 Chevrolet Silverado 1500 High Country Engine: 6.2L L87 V8 Recall: N252494001 – L87 Engine Loss of Propulsion I am submitting this complaint to report a serious safety defect involving my 2024 Chevrolet Silverado 1500 High Country related to NHTSA Safety Recall N252494001 (L87 Engine – Loss of Propulsion). My vehicle experienced a sudden engine failure consistent with the conditions described in the recall, resulting in loss of propulsion. Due to this failure, General Motors authorized a full engine replacement at an authorized GMC dealership. After the engine replacement was completed, the replacement engine also failed in the same manner as the original engine, again resulting in loss of propulsion. This second failure occurred despite the vehicle being repaired according to General Motors’ recall procedures and specifications. Loss of propulsion creates a significant safety risk, especially while driving at highway speeds or in traffic, as it can lead to sudden power loss without warning and increases the risk of a crash. Despite the replacement engine failing in the same way as the original recalled engine, General Motors is now refusing to replace the second failed engine or provide a permanent remedy. As a result, my vehicle remains unsafe to operate and unresolved under the existing safety recall. I am concerned that the recall remedy is inadequate and that replacement engines may also contain the same defect, creating an ongoing safety hazard. I am requesting that NHTSA review this matter to determine whether the recall repair is effective and whether additional corrective action is necessary to protect vehicle owners.

The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that on one occasion, while attempting to stop the vehicle, the brake was depressed and the rear wheels locked up, and the vehicle jerked extremely hard. The contact stated that when the vehicle jerked, it felt like another vehicle had crashed into the rear of the vehicle. Additionally, the contact stated that on several occasions, while releasing the accelerator pedal, the transmission downshifted extremely hard. There were no warning lights illuminated. The vehicle was taken to a dealer, where it was diagnosed, and determined that the valve body in the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 10,000.

On multiple occasion parking sensors activate for no reason. Emergency braking occurred while backing as well as while driving for no reason at all. High possibility of a crash occurring. Gm refuses to repair or replace. Gm stated dealer says vehicle has completed repairs and vehicle ready for pickup. Dealer has not repaired or replaced any items or parts.

GM is not handle this recall in a timely manner. They are refusing to inspect vehicle to see of there are any defects. This is concerning, as based on the recall notice, the engine may fail at anytime. This could cause a crash or leave me or my wife stranded on some road. My dealer would do the inspection but to do the inspection but they said they are not allowed until I have gotten "permission" from GM. This is a safety concern for me and my family and GM is not handling this appropriately. An immediate inspection should be done ensuring if the vehicle is safe to drive.

Truck will randomly throw codes for service 4wd and forward collision unavailable, rear cross traffic unavailable, lane departure will not work, auto high beams not work, and if parked position truck will not release Park brake making truck unable to be moved. Truck has been in and out of certified dealer 3 times and problems still occurring at random. Dealer has stated they are not able to duplicate issues and can't do anything. Issues happening pose risk while driving when codes come on making all standard safety features not to work in event of a accident. Also making truck not mobile when Park brake sets in event of accident.

My truck had approximately 55,000 miles on it when the incident happened. I pulled out of a store and began going down the road and the rear wheels locked up slamming everything forward and the truck and leaving us almost rear ended. The truck was stuck in one gear after breaking the tires free with check engine lights flashing and the dash saying reduced power. It has since been at the dealership for 3 months waiting on a valve body with no end in sight. There is apparently a national back order on these faulty parts because of how common this high speed rear wheel lockup is so I am left without a vehicle or an end in sight.

While in traffic over 45 miles per hour, the vehicle placed itself into a hazard mode due to the electric vehicle propulsion system. This happened so fast and the deceleration rate was so quick that it risked a rear end collision. This is the second time this has happened and both were following a heavy rain storm. I drove through a modest puddle that did not even submerge half of the tire wall making contact with the road and did so slowly. Less than five miles later, the vehicle goes into what my service advisor calls "limp mode." I have asked General Motors to give me an even exchange or, in lieu of the fear this vehicle gave me, an upgrade to a Cadillac Escalade IQ.

On 7 or 8 occasions while navigating parking lots/driveway turnaround, i bumped the resume switch on the steering wheel and the truck took off accelerating rapidly from 2-4 mph speed until I disengaged with the brake. Someone with slower reactions or unaware of what is going on is going to get hurt by this. I believe it's tied to collision avoidance system and the adaptive cruise control mode. This system will allow cruise to stay engaged even as it slows you to a halt in, e.g. a rush hour slowdown, but if it slows you to some speed just greater than zero, and the traffic ahead speeds up, it will speed back up to the cruise setting. Similarly, when cruise is disengaged by brake action, but there is still a stored value in cruise control, if you accidentally hit resume at slow speeds the logic is treating it like a traffic situation. So the old 20 or 25mph minimum engagement speed no longer applies. As for why I inadvertently hit resume, it has to do with the raised momentary rocker switch at the 9 oclock position on the steering wheel. If you make a turn with your palm against steering wheel. For example, on a left turn, if the wheel is turning counterclockwise and your left palm is in the 9 o'clock position, it can rub against the raised cruise control rocker triggering the resume function, and off she will go! A flush or recessed button/switch would have been a better choice here. At this point, a software change would be the best solution to ignore the resume function below a certain speed.

I was making a right turn and my signal started flashing faster than normal and stated service passenger front turn lamp. There is no way of service without replacing the entire headlight which is $2000.00 for one side. Took to gm dealer about a month ago to diagnose the opposite side and they stated warranty will not cover it. The truck had approximately 76k miles on it when the driver side was looked at and the passenger side was with 78k miles. I have contacted gm warranty claims department twice now to put it all on record. It’s a major safety concern when I have no turn signals on the front which could easily cause a crash. It also is a concern of being pulled over by any law official for something that I can not control and it’s not like I can just go to a local parts store to get a bulb on a weekend due to a poor design by General Motors. Other trucks of the same year with the same headlights that I have are being recalled due to the same issues but since my build date doesn’t fall into that category they do not want to take the responsibility of making things right or help prevent safety incidents from happening that could cause harm their customers and innocent bystanders

I am 6'2" tall. The shoulder straps on both the drivers and passenger side do not adjust up far enough to protect me in the event of a crash. The straps slip down below my shoulder. This is due to the fact that the WT model does not have power seats, so I am unable to lower my seating position to a safe level. If the seat could be lowered, the shoulder straps would sit properly above my shoulder. In the event of a crash the shoulder strap will be totally useless.

While pulling my Vilano fifth wheel trailer to Alabama from my home state of Texas the driver information center alerted me that the trailer brakes were disconnected. Then a short while later it alerted that trailer brakes were connected. This situation continued for the entire trip to Alabama. When the info center indicated trailer brakes were disconnected, they were indeed not working. Several times I almost rear ended cars stopping in front of me. (The vehicle had a recall notice urging to take it in and replace the brake module shortly after purchasing it. I did this.) Once I arrived in Alabama I took the vehicle to the Chevrolet dealership in Foley, Alabama to check the braking system. They told me there was no problem with the braking system. I retrurned to my home in Little Elm, Texas with the problem occurring the entire trip. I finally made it home and today took the vehicle to James Wood Chevrolet in Denton, Texas to have the braking systme checked again. They told me there was nothing wrong with the braking system. The service writer did say that because the trailer has LED lights the braking system does not recognize the voltage from the trailer and that is why the brakes are disconnecting. Please help me find out how to correct this extremely dangerous condition while I am towing my 16,000 pound fifth wheel trailer.

Since purchasing this truck 06/30/2024; during the 9100 miles driven, electrical issues such as check engine, EWS needs to be serviced, Forward Collision Service, Stereo screen freezing up, Tire Pressure stating air is needed but checked air pressure, it is where it should be, Right Signal Trailer service needed but not pulling a trailer. Three times after starting the truck it failed to go into reverse, stuck in neutral. Two of the three times it was able to reset after 10 minutes of shutting down the truck and restarting. Third time had to get the truck towed due to unable to reverse out of parking spot. When driving it seems as if the truck is stuck in 2nd gear while trying to accelerate, rough driving at times. When car turns off it makes knocking noise and sounds like it is trying to turn off electrically. Tailgate would open while driving even though shut and checked. Driver seat motor failing while trying to move the seat. Middle seat stays in upright locked position for days before it will release. Dealership is stating that valve body needs to be changed but will take up to 6-8 months due to backordered part, but no loaner car is available. Will have to be without a vehicle for the entire time. All is covered under warranty.

I’ve had 3 occasions of this brand new vehicles front collision avoidance system going off HARD and locking up the brakes. It scared the crap out of me as there was nothing in front of me - if I hadn’t known the truck had automatic collision software - I’d have driven to the Chevy Dealership right then. The first time I thought it was a fluke. The second time it really caught me off guard. The third time (inside 2 months) I realized there is something not right. I reported it to the dealership but they wanted me to trade it in for a new truck. Sorry, no. I just want to report this problem as I’ve seen a recall on other vehicles with 10 speed transmissions. Their shifting problem - is also present in the Chevy Silverado Truck - but it has not impacted my use of….

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the transmission shuddered and the vehicle hesitated. Additionally, the contact stated that the transmission vibrated, and the vehicle jerked forward. The contact stated that while parking in a parking lot, the vehicle jerked forward and crashed into an accessible parking sign, causing a dent in the front bumper. The vehicle was taken to the dealer; however, the failure was not duplicated. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 1,600.

The contact owns a 2024 Chevrolet Silverado HD Crew. The contact stated while driving at 45 MPH on a green traffic light, another vehicle was attempting to turn left while distracted by her phone. The contact veered to the left to avoid crashing with the other vehicle but was unsuccessful and landed 15 feet forward after the collision. No air bags were deployed, causing both the driver and passenger to be injured. The contact stated he sustained injuries on both his left and right hand and lower back, for which he was currently receiving treatment. No information was available on the other individual injured. The damage to the vehicle was on the front passenger's side. No warning light illuminated. The vehicle was then taken to a dealer where it was pending a diagnosis however the frame was to be welded however due to the metal material the contact was concerned about it being back on the roadway. The vehicle was not repaired. The manufacturer was not made aware of the issue. The failure mileage was approximately 62,000.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving at 70 MPH, the vehicle stalled and lost motive power. The contact was unable to restart the vehicle. The contact was driving on a major highway in the fast lane during the failure. The contact was concerned that the failure could have caused a major crash. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 9,000.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that after the vehicle was serviced at the local dealer for a manufacturer software update the vehicle's display console began to experience failures causing several safety features to become inoperable. Later, while driving in reverse the vehicle crashed into the pole. During the incident, the collision avoidance feature to alert the driver was not activated. The contact indicated that as the vehicle drove closer to the pole the driver's seat did not vibrate, the audible alarm was not active and the warning message was not displayed to alert the driver of an impending crash into the pole. During the crash, the contact experienced an injured back that did not require medical attention at the time. No police report was filed and the vehicle was driven from the scene. The manufacturer and local dealer were notified of the failure but no assistance was offered. The failure mileage was 10,500.

I was driving down the road when the vehicle shut off and required a restart. After I was able to safely pull to the side of the road with zero power I was able to restart the vehicle after a few tries. The check engine light came on. Upon getting the code checked the CAM sensor is what shut the vehicle off. I was on a busy access road and a crash could have happened if I was not able to move out of the travel lanes.

The issue involved multiple systems, including the ABS system, brake system, and electronic stability system (ESG), along with a significant loss of braking power. These components may still be available for inspection. My safety and that of others were seriously at risk during my morning commute in the Atlanta metropolitan area. The truck lost braking capability, nearly causing a collision with the vehicle in front of me. Later, as I attempted to park, it again lost braking force, and I narrowly avoided crashing into bushes. The collision prevention system also failed to activate during these incidents. The problem was inspected and diagnosed by the dealership after being towed via roadside assistance. They confirmed that the battery caused the failures across multiple systems. This was not the first issue with the battery. About a month ago, the battery suddenly died, preventing the truck from starting. At that time, Chevrolet sent me a message stating that the battery status was critical. After recharging it, the vehicle functioned normally until this recent incident. The first symptoms of the latest issue appeared while I was stopped at a red light. The truck suddenly shut off and restarted on its own. Warning lights for the ABS system and brake system appeared on the dashboard. Once the light turned green and I started to accelerate, an ESG message appeared, followed by another message limiting the maximum speed to 43 mph. When I tried to brake to park the truck, the brakes were slow to respond, making it feel like the truck had completely lost braking power. The collision prevention system failed to activate, increasing the danger. Fortunately, my two babies were not in the truck at the time of the incident. This was an extremely frightening situation for me as a driver. The truck is only six months old, has 37,000 miles, and was purchased new. I believe many of these failures could have been prevented with proper safeguards. While I was lucky to avoid an

While using adaptive cruise control, the system can detect a vehicle and immediately apply the brakes or slow down. In some cases, it may detect a vehicle (the vehicle icon appears) and trigger an immediate red collision light flash, followed by automatic braking. However, during these events, there were no cars ahead of the vehicle. There was no obstruction of sensors or cameras, and the incidents occurred in various weather conditions, including rain, snow, and clear days, both during the day and night. If the road is slick or slippery, this could potentially lead to a loss of control. Additionally, if another vehicle is following closely behind, it could result in a collision.

The forward collision warning light just came on and has been on for five days. Nothing happened, no wreck, no bumping into anything. I have researched and found others that have had the same problem. I tried removing the F11 fuse and leaving it out for 15 minutes as well as replacing it. I’ve insured that the windshield is clean and cameras are not blocked. I’ve used the settings in the main screen to turn the option on and off and it still stays on. I’ve checked for updates but didn’t find any. I called the dealership and they couldn’t help and said bring the truck in.

My husband hit another vehicle, then proceeded across the road and crashed into a telephone pole. The airbags did not deploy. However the vehicle called onstar to report the crash. The nc state trooper and the towing company both indicated that they were also shocked that the air bags did not deploy. This is a brand new vehicle with 1100 miles and has been declared a total loss due to the severity of the front end damage. The the body shop was also commenting on this fact.

Trailer brake controller repeatedly failed. The TBC would turn on and off randomly, the trailer we were towing then had no trailer brakes. This has aTSB associated with it, but this is a safety issue and should be a safety recall. The TSB is 23-NA-149. I am a mechanical engineer and my wife is a software engineer and we spent many hours troubleshooting this on the road away from home. GM must be compelled to elevate this to a Recall as the condition of no trailer brakes can lead to a crash and deaths. Thank you.

The vehicle was involved in a single vehicle roll over crash. The sheet metal of the roof pealed down and away from the frame of the vehicle. The windshield separated from the metal at the top portion of the windshield. The metal then began to separate from underneath the weld along the sides of the roof. The metal was then rolled inward into the passenger compartment of the vehicle. The metal pinned the front passenger seat back down and to the right against the passenger side B-pillar. Both A-pillars did not sustain any structural damage as the result of the crash.
