2021 Tesla Model 3 Standard Range Plus RWD

2 problems 1,Phantom braking when cruise control is activated. 2, There's no rear door mechanical release in the event of a electrical power failure in the event of R.T.A

The components involved are the automatic emergency braking (AEB) system and the airbag system. During the collision, the AEB system did not activate, and the airbags did not deploy. The vehicle is available for inspection upon request. I was driving on a main roadway with no stop signs or traffic controls in my direction when another driver entered from a side street with a stop sign and pulled directly in front of me. I was unable to avoid the collision, and my vehicle was struck the other vehicle. The failure of the AEB system to engage and the airbags not deploying increased the risk of injury to myself and could have posed a risk to others involved. The issue has not been reproduced, and it has not yet been confirmed by a dealer or independent service center. The vehicle has been inspected by police and insurance representatives. The other driver was determined to be at fault. I am in the process of addressing the incident with the manufacturer. There were no warning lights, messages, or prior symptoms indicating any issue with the braking or airbag systems before the collision.

- The rear middle seatbelt became locked and will not unwind or extend. The seatbelt remained stuck in the retracted position, making it unusable. The vehicle and seatbelt assembly are available for inspection upon request. However, Tesla has already fixed the issue, but I feel we were wrongly charged because I believe this should be a recall. I searched this issue online, and others have reported the same issue. Because we rarely have the need to use our rear seats, it wasn't until years later we discovered this issue. - Because the rear middle seatbelt cannot be extended, that seating position cannot safely be used. Any passenger sitting in that position would not have a functioning restraint system in the event of a collision, creating a safety risk. - Yes, Tesla service inspected the vehicle and confirmed that the rear middle seatbelt was locked and not functioning properly. - The vehicle has been inspected by Tesla service. It has not been inspected by police, insurance representatives, or other third parties. - No warning lights, alerts, or messages appeared prior to discovering the issue. The seatbelt was found to be locked when we attempted to use it, and it would not extend.

The driver’s side belt makes a “click” sound when latch is inserted into the locking component but at times does NOT remain lock and the belt is released shortly after. The issue is sporadic. The belt is released with a low amount of force i.e. adjusting the body in the seat or twisting body to look over the shoulder

Tesla full self driving software malfunctioned and turned into oncoming traffic lanes instead of crossing over to the correct opposite side of the roadway. This occurred after getting off a on ramp in Ukiah, California around 2am Nov 15, 2025. This could have put others in serious danger if there were cars coming in the oncoming lanes heading in the different direction. The problem has not been reproduced by a dealer or other entity. Yet This has happened to other tesla drivers as well using FSD as you are probably already aware. No inspection and it was sudden and unexpected.

I drove into my neighbor’s driveway to drop her off. As I slowed down and applied the brakes to stop, the car failed to respond. It continued forward, running over the flower and plant pots at the edge of the driveway, crossing the backyard, and finally colliding with the trees and bushes at the rear of the property. All airbags deployed, and the vehicle was damaged beyond repair.

Steering wheel is peeling/degrading and causing difficulties with steering and control.

Steering rack failure. Steering assist, auto pilot and lane departure prevention failed and would not work properly so this is a safety issue. Manual steering worked fine but the safety and auto pilot functions would no longer function. Paid for Tesla service over $3,000 to replace steering rack and now is working properly. Reporting this as this may happen to others and probably should be a proactive recall on the steering racks so others don't lose these safety features. Maybe related to computer as it failed, worked again and then failed again and was then repaired by Tesla service center.

Driver belt latch failed while driving

While driving a Tesla 2021 model 3 tonight at 8:45 P.M. turning left the wheels locked to the left and would not turn straight causing me to hit a concrete divider. After hitting concrete divider steering released to normal driving but driver side car front rim tire was damaged and wheel alignment misdirected.

What component or system failed or malfunctioned, and is it available for inspection upon request? - ABS, Automatic Emergency Braking, Traction Control, Stability Control failed while braking using the regenerative braking. How was your safety or the safety of others put at risk? - While coming to a stop using the regenerative braking, the regenerative braking immedietely ceased to work, and the driver had to immediately apply the hydraulic brakes to avoid a rear end collision Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - No, they appeared while braking. This issue is not new to this vehicle and has happened in the past, however the errors cleared themselves out.

On [Wednesday, 07/09/2025], I was driving my Tesla Model 3 in rainy conditions when the vehicle suddenly swerved and crashed into a sidewall. The road was wet but not flooded, and I was traveling at a moderate speed. As I lifted my foot off the accelerator to slow down, the car's regenerative braking system engaged abruptly, which I believe shifted weight forward and caused the rear tires to lose traction. This led to hydroplaning and complete loss of control. There were no warning lights or alerts prior to the incident. The road surface did not have visible hazards or standing water that would typically explain a spinout. The tires were moderately worn but within usable limits. As a result of the crash, the car was declared a total loss. The insurance company now has possession of the vehicle. Thankfully, no one was injured, but the crash was severe. After the incident, I researched similar cases and found multiple reports and articles (e.g., AutoEvolution) linking Tesla’s regenerative braking to increased risk of hydroplaning or loss of control in wet or slippery conditions. The regen system eliminates coasting and applies braking force immediately upon throttle lift-off, which appears to be a safety risk in reduced-traction environments like rain, snow, or ice. I believe this issue deserves investigation, as it may affect the safety of other Tesla drivers in similar weather conditions.

Correction: Retrofit SBR in OCS Equipped Front Passenger Seat - Remove and Replace. FIRST ROW - SEAT BELT REMINDER SENSOR BOX CLIP (1130363-00-B), FIRST ROW OCCUPANCY SENSOR(1099592-00-F) FIRST ROW SEAT HARNESS ASSEMBLY - RIGHT HAND (1489060- 03-G). This car has 69k miles and I'm informed this is out of warranty and has a cost of $696.75 to repair on a car that is less than 4 years old. Saying the sensor failed is not accurate as the error does not exist unless there is someone in the passenger seat which tells me the sensor is working somewhat. Tesla will not inform me of what will and will not work in the event of a collision but that these items need to be replaced to make sure safety of occupant's. I am skeptical since safety is your number one concern and should be the concern of every auto manufacturer. Unless damage by the owner specifically, how and why is this not covered for the life of the vehicle?

Incident Details: • Date of Incident: [XXX] • Time: [XXX] • Location: San antonio, Tx • Weather/Road Conditions: Clear, dry highway; 90 F • Speed: 60 mph; • Description: while driving my 2021 Tesla Model 3 with Full Self-Driving (FSD) software version 12.6.4 engaged, the vehicle unexpectedly changed lanes without my input, likely due to the Auto Lane Change feature. Immediately after, it braked hard for and unrecognized slowing traffic ahead. This sudden jolt caused immediate pain in my upper back, neck, and chest, which persists. I believe FSD misjudged traffic patterns or road conditions, a known issue with v12.6.4 based on online reports. The incident occurred in heavy traffic and no crash occurred, but the abrupt braking posed a safety risk and caused injury. I’m unable to see a doctor today but plan to soon for a diagnosis. This is a serious safety concern, as FSD’s erratic behavior could cause collisions or further injuries. Injuries: Yes, back, neck, and chest pain caused by sudden braking. No medical diagnosis yet; planning to see a doctor soon.

RCM2_a636 Front passenger safety restraint system fault Service is required Passenger airbag turns OFF when a passenger is sitting in it. Error is intermittent and while occasionally turn off and on. Seems like a lawsuit waiting to happen should someone get in a car accident.

On [XXX] at approximately [XXX] on [XXX] in Oakland, CA, I was intending to park the car on the street at the curb. As I started to pull to the side of the road to park, the brake suddenly fully engaged, bringing the car to an immediate complete stop. My foot was not on the brake at the time. There were no obstructions of any kind in the road or in front of the vehicle. No warning sounds, messages or lights were activated before, during or after the incident. The incident caused no injuries, because of the low speed at the time, just a sudden jerk forward. However, if the event had occurred at a higher speed, some kind of injury would have been likely. I am also reporting the incident directly to Tesla. There has been no testing or inspection of the vehicle. The vehicle will be made available for inspection or testing if requested.

Attempting to park. Slowly inching forward while turning left. Vehicle accelerated. (Sudden Unintended Acceleration: SUA) Vehicle jumped a curb, bounced off a tree, dropped off the curb before comping to a stop. Internet search shows other similar reports; attributed, by Tesla, as pedal misapplication. This was not "pedal misapplication". I am not looking for anything. But NHTSA should increment occurance counter by 1. Tesla has a problem. Electrical or Mechanical...do not know. They have also lost me as a customer. The car will be sold. I have video...mp4

vehicle constantly phantom brakes while driving. i have reported 100+ incidents thru my tesla "report bug" feature. It will read the speed limit sign on the off ramp and slow the vehicle down 20mps abruptly, it will see a car on an onramp and slam the brakes on thinking there is a collision coming. it is every single day using cruise control

The rear doors in this vehicle have no manual open option in case of a power outage such as a fire or submersion. This is a huge safety risk for back seat passengers, who are more likely than average to be children who could not figure out what to do in the case of an emergency

The contact owns a 2021 Tesla Model 3. The contact stated that while a family member was attempting to use the rear middle seat belt, the seat belt failed to extend and was unusable. The vehicle was taken to a Tesla Service Center, where the seat belt was replaced. The vehicle was repaired as an out-of-pocket expense. The manufacturer was notified of the failure. The failure mileage was approximately 65,000.

The contact owns a 2021 Tesla Model 3. The contact stated while driving approximately 65 MPH, the braking system erroneously activated, causing the vehicle to abruptly decelerate. The contact stated that the failure was due to a failure with the computer reading the speed limit as 45 MPH instead of 65 MPH. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 35,000.

1. Autosteer/Lane assist failure, yes its available for inspection upon request with Tesla 2. Due to above failure met with a crash which led to severe medical issues 3. The car has been totalled and the car is not functional, waiting on Tesla to inspect and confirm 4. Police has filed a crash report but manufacturer, insurance yet to inspect the vehicle or component 5. Absolutely NO WARNING lamps/messages prior to the failure.

While driving, I started to hear a creaking sound while backing up and turning the wheel left. The sound became worse over the course of a few weeks. The steering also felt a little loose. I reached out to the manufacturer for a service appointment, and could only be scheduled about a month out. After a few weeks, while trying to parallel park, the car felt like a tire was stuck, or had a flat. I stopped the car to look at all of the tires and they looked fine. When I returned home, I tried to recreate the issue with my wife moving the car slowly from the driver seat while I looked at the wheels. As she turned and backed up, the creaking sound was very loud, but the tires looked fine. When she put the car in drive and began to pull back into the driveway, I could see the front passenger tire was turned abnormally far to the left, looked like it was leaning, and it was locked (not rolling). Once we had the car in a safe position, I jacked up the car and looked at the passenger control arm to see a bolt completely missing from the front suspension lateral link. The other bolt was 1/2 of the way out and barely holding on. If this had come apart at highway speeds, I am afraid it could have killed or seriously injured my family.

Front passenger safety restraint system fault in sensor, sensors won’t stop going off and giving me warnings while driving.

Front passenger safety restraint system fault alert popping up every few minutes while driving. It is the most irritating thing and there is no way for me to fix it without spending over $500 dollars. This is seemingly a common problem for this make and model through reddit posts and car forums. I was also told by a employee at the tesla service center that they see this very often. It is shocking that Tesla hasn’t taken responsibility in fixing this, when there is nothing any of us could’ve done to have this happen. I’ve seen people get quoted anywhere from $500-2,000 for this exact problem. It is so beyond distracting while driving.

lost power steering suddenly on the road.

Rear left seatbelt randomly stopped latching properly. Seat belt buckle goes into the latch but doesn't stick inside and just slides right out.

I am writing to report a serious safety concern regarding the non-deployment of airbags during a recent traffic accident. The incident involved a collision where I was struck on the driver’s side front. Despite the severity of the impact, the airbags did not deploy, which raises significant concerns about the effectiveness and reliability of the airbag system in such scenarios. Incident Overview •Accident Type: Collision with impact on the driver’s side front •Airbag Response: No airbag deployment Safety Concerns The non-deployment of the airbags during this incident is alarming, as airbags are a critical safety feature designed to protect occupants during a collision. In this case, the failure of the airbags to activate could have resulted in serious injury or even death, depending on the circumstances. The lack of deployment suggests a potential defect in the airbag system that may compromise the safety of other vehicles of the same make or model.

Passenger SRS system fault. Initial error is due to a fault with the occupancy sensor. Presumably disabling or degrading seatbelt pre accident tensioning and proper airbag deployment. Also causes repeated & distracting beeps throughout drive.

Ever since Tesla rolled out an update for everyone to beta test FSD, the adaptive cruise control has been changing speeds when near interstate type exits and entrances. I've had it change from 75 down to 40 mph which is dangerous in traffic. This change in speed some times is just a drop to the next 5mph increment, such as from 73 to 70. Sometimes it is more from 73 to 65 at the same place/exit. It is not consistent. The only thing consistent is it's near exits even when not in an exit lane or nearest lane to the exit. This "Feature" needs to be removed as it is unpredictable which makes it dangerous.

Tesla ADAS detects non existent objects and issues collision alerts and phantom brakes randomly if there is no cars in front of the Tesla, braking abruptly and almost getting me into rear end accidents. Tesla ADAS freaks out when making lane changes randomly, shaking violently and giving the driver and its passengers a fishtailing simulation. Auto wiper triggers randomly while it's sunny, distracting the driver and forcing an interaction on the center console to stop it. Auto wiper cannot be turned off as it reengages upon using Tesla ADAS. The rear view camera lags. It stutters and shows me a delayed view. Compounded by the Model 3's very small rear view mirrors and side mirrors, this is incredibly dangerous as I have no way of gaining sufficient visibility of the back of the car. Tesla service told me this is all normal.

The contact owns a 2021 Tesla Model 3. The contact stated that while driving approximately 40 MPH, the vehicle made a violent right turn inadvertently crashed into a ditch, and rolled on the driveway. The contact sustained a concision. Medical attention was needed. A police report was filed. The vehicle was towed to a lot. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 44,410.

This car, like many Teslas, is experiencing what has been come to be known as phantom braking. When in the autopilot or full self driving, this car will occasionally to frequently, depending on the day, suddenly break where it will decelerate from say 65 mph to 45 or 50 in a very short period of time. This can happen in very busy traffic conditions. It seems to happen when I'm going faster rather than slower. For example, I haven't experienced it so much on City Street. It seems much more prominent on highways. This is an issue that has many YouTube videos about. It has been reported by many Tesla owners as well as the media.

Latest update changed the cruise control to force inclusion of autopilot. Cruise control function is now unavailable with without this autonomous feature. It's not only distracting, but aggravating. What's worse, is there's no online ability to inform or complain directly to Tesla. This isn't the first safety-related software glitch. Please get them to fix these issues.

I was driving in the street at 10 miles, I turned to the right and I push the break but the car didn't break and I crashed with the car in front of me.

While driving [XXX] on [XXX] in Texas, the Tesla autopilot abruptly and forcibly applied the brakes while I was driving approximately 77 mph. I was almost rear ended by a semi truck due to this issue. This happened again about 20 miles down the road and I disengaged the cruise control and autopilot altogether at that point. This is a continuous problem that needs to be addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2021 Tesla Model 3 has various issues with the auto pilot feature. When engaged the car makes sudden and abrupt stops while driving. This has happened various times while driving on the freeway when there were no obstructions present. The autopilot feature also prompts to change to the right lane, when dismissed the prompt appears again repeatedly. This is repeated throughout the drive and poses a major distraction. There was supposed to be an “over-the-air” correction but my vehicle has never received the software update.

The contact owned a 2021 Tesla Model 3. The contact stated that after reversing out of a parking space, then shifting to the drive position and lightly pressing the accelerator pedal the vehicle suddenly experienced unintended acceleration and drove forward at a very high rate of speed. The vehicle drove across a street and crashed into a building. During the crash, the driver sustained an upper torso and neck injury and was transported to the hospital. One person inside the building was also injured during the incident. No further information was available. The vehicle was destroyed and towed away. A police report was taken at the scene. The manufacturer was notified of the incident. The failure mileage was 12,400.

The contact owns a 2021 Tesla Model 3. The contact stated that while attempting to park at 5 MPH, the brake pedal was depressed however the vehicle accelerated independently. As a result, the contact crashed into the two parked vehicles on the side of the parking space she was attempting to park. No air bags were deployed. One parked vehicle had an occupant and the other was unoccupied. There were no injuries or medical attention required. A police report was filed. The manufacturer was made aware of the failure and the vehicle was taken to an unknown dealer where it was unable to be diagnosed due to no available appointment. The dealer then suggested the vehicle be towed to the contact's residence where it currently remains in the garage. Tesla informed the contact that the brake system would not be inspected until she repaired the crash cosmetic damage to the vehicle. The approximate failure mileage was 33,000.

The rear middle seatbelt has permanently locked and is unusable. It occurred after having the rear seats folded down and was observed when replacing the seat-backs to their normal position. Tesla has refused to repair due to vehicle being out of warranty despite the vehicle not having been involved in any collision.
