2022 Kia Niro Electric

Intermittent warning to "Refill Inverter Coolant" displays on the dash screen. This is a known issue pursuant to SA512 (ELE 270 Rev 3) due to faulty coolant that crystallizes and interferes with the sensor. However, per Kia, it is only covered under standard warranty (5 years/60k miles) and while my vehicle is within the year warranty, it is over the mileage. Quote was to replace "Chiller, water pump and flush coolant system" at a cost of $2369.02 including parts and labor. Dealership will not perform recommended maintenance of coolant flush (every 37k miles) without replacing these parts. If this was a known defect why is there a limitation to the SA? It should be covered as a recall, not a voluntary service alert. I am unable to properly monitor the in-dash warnings regarding coolant levels until this problem is fixed

The vehicle has a recurring P0420 code (“Catalyst System Efficiency Below Threshold Bank 1”). A boroscope inspection at Ricardo Caballero Kia Santa Isabel (invoice #[XXX] dated December 5, 2025) confirmed internal disintegration of the catalytic converter, with physical pieces of the catalyst falling out when the exhaust pipe was removed. This failure appears related to Recall 23V534 (SC276) and TSB PS709 (overheating / coolant boiling issues in 2017-2022 Niro Hybrid models). Motorambar, Inc. (official Kia distributor in Puerto Rico) has ignored my warranty claim since December 2 and December 22, 2025 (more than four months). Motorambar is now refusing to authorize a courtesy loaner vehicle at the dealer Ricardo Caballero Kia Santa Isabel, claiming the tests will take less than 5 days. This leaves me without transportation. The catalytic converter is fully covered under the Federal Emissions Warranty (8 years / 80,000 miles). I request that NHTSA investigate this as a potential safety and emissions defect and require Kia / Motorambar to: 1. Immediately repair or replace the catalytic converter under warranty at no cost. 2. Provide a courtesy loaner vehicle during the repair. 3. Reimburse previous diagnostic costs of $449.17.

The contact owns a 2022 Kia Niro. The contact stated that the rearview camera displayed a distorted image while the vehicle was in reverse(R). The failure obstructed the driver's visibility, preventing the driver from safely operating the vehicle. Additionally, there was a delay with the image appearing on the screen when the vehicle was in reverse(R). The vehicle was taken to the dealer, but it was unknown if the vehicle was repaired. The contact stated that on a separate occasion, the vehicle failed to start up, with the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the battery terminals were loose. The vehicle was repaired; however, when the contact arrived to retrieve the vehicle, the vehicle failed to start. The dealer inspected the vehicle; however, no cause for the failure was found. The contact was informed by the dealer that the vehicle had an recall campaigns needing VIN-specific checks, NHTSA Campaign Number: 25V426000 (BACK OVER PREVENTION). The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 45,000.

Vehicle with code p0420, Kia dealership technician say: the problem was the spark, proceeded to change it and clear code. Check engine turn on again, the same person say: it’s a ring piston, the car was leaked engine oil to exhaust and he see blue smoke, no evidence for part of dealership and dealership never mention the car was consuming excessive engine oil. I mentioned the law of emission to change the catalyst and the boss say: I can’t change it but the problem will be come but never do anything to change it. In other dealership Kia the technician dismantle the exhaust and see ceramic part coming from the catalyst, his recommendation is change it. Dealership make a formal petition to motorambar distributor official ok Kia in PR and motorambar refuse to change the part with the evidence provide by dealership: technician report and photos. I call motorambar in 2 times and the only thing motorambar do is creating ticket to escalated to technician, never received call from this ticket, this occurred on fort week of December 2025 and today is 19 January of 2026 and not received any call from motorambar.

This car was purchased certified pre-owned from a Kia Dealership with 46,227 miles in October 2024. Within a month (Nov 2024), the electrical system would die overnight and we would require a jump start. This seemed to align with colder temperatures. After the first or second jump start, a headlight blew out. We replaced it. Then a tail light blew out and we replaced that one too. It seemed that there must be a connection between the electrical failure and the headlights / tail lights burning out. We took it in for a software update to see if that solved it, we also had them check the hybrid battery and the 12V battery. No other issues were detected. Eventually the problem just stopped happening. Now in Nov 2025, a year later, the problem has returned. The car's electrical system dies overnight and we have to jump start the car. And another tail light / turn signal has burned out. This time, we called a dealership to ask about any recalls or pending software updates and they said there was nothing showing in their system. We are now driving without a turn signal, which is a significant safety hazard. We will have to go back and replace the tail light / turn signal bulb. But what about the situation recurring? How do we get the car to stop 'dying' overnight in cold weather?

I wanted to go to the store and when I pressed the Start button I got the message: Stop car and check regenerative brakes. Soon after the lights dimmed and the message showed up that key fob was not detected even though it was in my hand. It then no longer took a charge and is completely dark. I checked the internet, and it sounds like it is the 12V battery and is a known issue that is not yet at recall level.

I have had this vehicle for 13 months and have taken it to the shop 4 times for the same reason. The 12v dies and my car has to be Jumpstarted in order for me to use the vehicle. Dealer usually blames the 12v at the beginning of the appointments before ultimately telling me there is nothing wrong with the 12v and that they are unable to replicate the problem. They rarely go beyond preforming a drain test, despite me telling them that there is no drain. I've been stranded late at night because of this issue, and now keep a portable jumpstarter in my vehicle at all times.

I was called for battery recall. Brought my car at the kia of stockton dealership last Feb 14, 2025. Mechanic found problem with high voltage battery of my 2022 kia niro ev. Contacted kia manufacturer or customer care regularly for the repair/problem with case number [XXX] but until now june 16th, 2025 no updates yet(4 months).

express my concern regarding a persistent and unresolved defect in the 12-volt battery of my 2022 Kia Niro, which I purchased from Hanlees Kia in 2022. In 2023, I brought my vehicle back to Hanlees Kia due to the battery dying prematurely. At that time, the dealership informed me of a battery jump start button on the dashboard. It was later revealed to me by Kia service in Stockton—after the vehicle was held for over two weeks—that the issue originates from the 12-volt battery located under the driver’s seat, which is defective. Despite this discovery, I was told by the dealership that even though the battery is defective that I should have brought the vehicle in earlier—specifically before 2025—to qualify for any warranty or replacement coverage. This is simply not true, as I did bring the car in promptly when I noticed the battery issues in 2023, but unfortunately, this did not result in a satisfactory resolution. Further, I am not alone in facing this issue. Several Kia Niro owners in have shared similar experiences on social media platforms, including Facebook. These owners have reported the same battery problems during their warranty period and were repeatedly told by dealerships that the cause of the issue was unknown, leaving them frustrated and without a solution. It is concerning that Kia engineers appear to have been aware of this defect for some time, as evidenced by the installation of the dashboard battery bypass button. This workaround indicates that Kia has acknowledged the problem internally but has not adequately addressed it for customers under warranty. As a loyal Kia customer, I respectfully request a full investigation and resolution of this battery defect issue, including an official acknowledgment of the defect and a replacement or repair under warranty. The inconvenience, safety concerns, and ongoing costs caused by this defect are unacceptable for a vehicle of this quality and price point. Thank you

I bought my 2022 Kia Niro EV new in 2022, and around 40,000 miles, I had a problem with the reduction motor so I replaced it, shortly after that I had a problem with the wheel so I replaced a part called the axle, and shortly after that, the other wheel had the same problem so I replaced the same part, and the Kia employee said that this part only breaks if there is a strong impact (traffic accident) so it's strange. All of this happened in less than 2 years but I had it covered under warranty so I got it fixed, but now the reduction motor problem that I had originally replaced has happened again and they are demanding $5,800 to repair it since it's out of warranty. I think this is unfair, and this is the first time I've had a car with this many problems in less than 3 years.

Car has broken down, not started, battery dead when fully charged MULTIPLE TIMES. It has been in the Kia service department since March 2024 (9 months) and they can’t figure out where the parasitic drain is from. This is the third time this year getting towed to the Kia dealership with no resolution. No warning lights / labels prior to failure. Danger by leaving me stranded 3+ times this year with need for triple A.

Vehicle has been submitted for repair under recall RCRIT-23V534-0846. DTC P17ED - Engine clutch system EOL fault, is set and has never gone away. Initially the dealership did the recall in the spring of 2024. It was taken to the dealership after an accident and returned with the same DTC. I believe the DTC was never repaired; it is a non-MIL light so it is easy to miss. It was taken back, and they claimed to bleed a clutch. DTC is still present. Taken back again, wiring harness was ordered and replaced, DTC is still present. The dealership (Serra Kia, 12300 30 Mile Rd, Washington Twp., MI 48095, 586-281-2800) has failed to fix this issue. The attached invoice is a 3rd attempt to fix the recall and they refused to do it at no cost.

I received a recall notice for my 2022 Kia Niro EV regarding the safety plugs of the high-voltage battery. I have now scheduled three different appointments with Kia of Lincolnwood to perform this recall, and each time I have been turned away with a different excuse (lack of part, lack of tools, performing recall will take too many hours). The last time I asked to speak with the service manager, who assured me he would take care of this and I would be able to come in on Friday 10/11. Given how many times I've been turned away, I called the day before to confirm, and the manager said he would call me back and never did. Repeated attempts to contact him or the dealership that day went unanswered. I would like help getting this dealership to perform the recall. Given the risk of fire or crash, I am not comfortable driving this vehicle or charging it. I am attaching copies of both the recall and the last work order I was given, where it shows once again I was asked to come back another day.

In re: Manufacturer Recall Number SC314, NHTSA Recall Number 24V358 The Kia dealership (Aloha Kia Leeward, Waipahu, Hawai‘i) is imposing an unreasonable delay for this safety recall. Dealer was contacted in mid-July to schedule recall service. Dealer said it had to order the part. After not hearing from the dealer for two weeks, dealer was contacted on August 2 and recall service was scheduled for August 27 (claiming that was the first available appt.) Dealer kept the vehicle for 5 hours that day, then said the service could not be performed. Dealer said it would contact me to reschedule. After leaving messages and not hearing back from dealer, I went in person on 9-4-24. Dealer could not schedule recall service until October 7. Because this is a recall for safety issues, this repeated delay is unacceptable. I wish to put this complaint in the record regarding the disregard for vehicle safety by Aloha Kia Leeward of Waipahu, Hawai‘i. Thank you.

I took my car to the Dublin California Kia dealer because my car would not start or allow me to open the doors. When I had it towed to the dealer they said that the lithium ion battery under the rear seat had swollen. They said they would first address the recall for the (HCA) recall number 23V534. They completed the recall and was given the okay to replace the battery. Car was in the shop for 2 weeks. When I got the car back I didn't drive for 4 days. When I went to drive the car it would not start again. I had the car towed to Kia Vacaville, California shop. They informed me that the recall was performed incorrectly at the first dealer and that the new battery under the rear seat was swollen. The car has been in the shop for 2 weeks again. I am very concerned that this is a dangerous problem and do not feel safe driving this vehicle.

The contact owns a 2022 Kia Niro. The contact received notification of NHTSA Campaign Number: 23V534000 (Power Train) however, the part to do the recall repair was not yet available. The dealer was made aware of the issue. The manufacturer was made aware of the issue. The contact recently received a recall notice that stated that parts were now available. The dealer was notified of the letter but stated that parts remained unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure. Parts distribution disconnect.

The contact's husband owns a 2022 Kia Niro. The contact received notification of NHTSA Campaign Number: 23V534000 (Power Train) however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

Started 2-3 months ago and is progressively getting worse. Battery drop from charged down to 2% randomly. Battery would drop 1% every 3 seconds. During highway drive it would cancel out cruise control and/or limited power down to 30mph. Which almost caused accident for the sudden loss of power. Brought to dealer and found no issues, waiting for next appointment in 2 weeks (next opening) to bring in for second look. Currently renting a vehicle since it is life threatening to just have no power in range and acceleration.

The contact owns a 2022 Kia Niro. The contact stated while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle failed to restart. The check engine and Hybrid System warning lights illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the hydraulic clutch actuator. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 23V534000 (Power Train). The VIN was included but parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact was referred to the NHTSA Hotline for assistance. VIN tool confirms parts not available. The failure mileage was 60,000.

Kia issued a recall warning dated September 29, 2023 regarding a fire hazard in our car. The recall stated that remedy was not available. After two months of no remedy from Kia and failure of Kia's Customer Care Center to respond to our requests for help, we went to the Kia dealer in Van Nuys, California to inspect the car to ascertain if it was still safe. The dealer refused to inspect or take any remedial action. To date there has been nothing from Kia to correct the problem. However, the 2023 and 2024 Kia Niro Hybrids do not have the fire hazard problem; these years were NOT in the recall warning. Kia should have offered a remedy by now since the problem was obviously corrected in the next two years.

I have now had 8 instances of the Low Power warning coming on while driving, which reduces available power, and when coming to a stop, car cannot go forward. This has happened at highway speeds as well as city street speeds. This happened 4 times on a 50 mile drive today, creating a very dangerous road situation. I now feel the car is unsafe to drive, as an accident is waiting to happen. I have contacted the dealership where car was purchased and am waiting to hear back from them.

2022 Kia Niro EV loses main battery power causing the vehicle to not be able to maintain speed. This has happened at varying speeds including highway speeds. The vehicle showes "limited power" warning on the dash along with "check electrical system" warnings. The OBDii system does not record these warnings and do not show up when taken to service center. The service center can not make repairs as they are not able to replicate the issue.

Vehicle enters power limited (turtle) mode randomly. While driving under normal conditions, with ample battery charge and range, the “turtle mode” warning indicator chimes. Sometimes it is brief and no noticeable power loss is experienced. However, often power will be lost and the vehicle must limp off the road to restart if it doesn’t resume on its own. This problem arises at varying speeds and ambient conditions. Our safety is at risk because you never know when it will happen. Losing power on the highway and making an emergency stop is clearly a safety hazard. The dealership has not been able to replicate this problem.

The vehicle has failed to start on 3 occasions and needed to be jumped. When towed to the dealership they’ve been unable to find any issues.

When driving with ACC engaged in traffic at a speed below the target speed the vehicle will sometimes speed up. This seems to happen when the ACC radar loses the return from the vehicle ahead -- for example when when a ahead vehicle changes lanes in stop-and-go traffic, I think this may happen if the side of the vehicle merging into the lane is relatively "clean" and most of the radar energy is reflected away. When this happens the car will start accelerating to the target speed, in rush hour traffic the spacing between vehicles can be quite tight and there is little time to respond to the sudden acceleration. This has also happened at an approach to a roundabout where there is a sharp turn before entering the roundabout. The vehicle is available for inspection. The problem has happened several times and I'm often able to predict when it will happen, but it has not been independently reproduced. The vehicle has not been inspected by the manufacturer (the problem was reported to the dealer who sold the car, they brushed it off and could not provide a means of reporting it to the manufacturer). There were no warnings or indication of an equipment failure.

After putting the car in park on a moderate slope, I exited the car and about 2 seconds later, as I was connecting the charger, the car rolled backward 4 feet before coming to a stop. I immediately confirmed that the car was in park. The parking brake was *not* on. (Or at least, I did not manually set it- I don't know if this car activates the brake automatically when in park.) The right front wheel was on ice. All other wheels on bare gravel. The temperature was 36 deg F. This is an EV, so it may have some sort of event recorder built in. If so, look at roughly 9:10 EST on 2/10/22. This is a short-term rental from Enterprise, so I'll set the parking brake manually for the remainder of the rental and report it to them on return. Contact them if you want to inspect it. The registration lists the owner as "EAN Holdings LLC"

When the KIA is shifted into "park", it will sometimes roll forward or backwards until the brakes are applied by the driver. This doesn't happen all the time and we have not figured out a way to predictably reproduce the results, but it happens a lot. My wife is the primary driver and I have only driven the car about 10 times. It has happened to just me twice in that time frame. It's such a common problem that we have started trying to routinely activate the emergency brake, as the transmission is not reliable in shifting the vehicle into park. During one incident, my wife forgot to use the emergency brake after shifting the car into park. She got out, the vehicle began rolling in park and her leg almost got ran over in an attempt to stop the vehicle. We have taken the car to Mike Miller KIA in Peoria, IL, but they were unable to reproduce the results, so did not take action to fix the vehicle. We have also reached out to KIA on this issue and are awaiting a response. A quick Google search indicated that KIA is not exactly reliable safety-related issues, so I wanted to be proactive in exposing this potential vehicle hazard.

This complaint is about a vehicle design and implementation issue rather than a malfunction. The implementation of the low speed warning alert for this vehicle is dangerous to pedestrians. Several times, as I was backing out of a parking spot pedestrians have stopped directly behind the moving vehicle and could have been hit. When put into reverse this vehicle emits beeping tone from a speaker mounted in the FRONT bumper of the vehicle. Because the backup alert tone is emitted from the front bumper of the vehicle, the sound is reflected off other cars and structures and is perceived as completely non-directional to anyone standing behind the car. When people hear the beeping, they tend to stop and look around for the source of the sound, which is some cases seems to be coming from 1 or 2 aisles over in the parking lot, or from another direction altogether. The tone that the car emits is also inconsistent with the usual and expected 1000Hz tone that most people associate with backup beepers, causing further confusion to pedestrians. As implemented, the backup alert system on this vehicle does more harm than good and has the potential to cause a pedestrian accident because of the confusing, non standard and non-directionality of the sound. A blind or vision impaired person would have a very hard time discerning the direction that the sound is coming from and could get hit by this vehicle as it is backing up. To be effective, the backup beeper should be mounted in the rear of the car and emit the standard tone that people generally associate with backup alarms.
