2022 Kia Niro

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? -I have received a "Check Brake Light" warning several times now, even after replacing the bulbs. I have replaced them twice now in the past 6 months and the issue persists. I believe it to be a faulty sensor or something similar. Yes, it is available to inspect upon request. How was your safety or the safety of others put at risk? I do not know if my brake light is functioning properly as this warning indicator comes on intermittently even though the light has been replaced and even when it seems there is nothing wrong with the light. It is very stressful. Has the problem been reproduced or confirmed by a dealer or independent service center? I took my car to the dealership in November 2025 and they couldn't find any issue. The indicator light did not come on at the dealership but came on again later in the week. They even replaced both brake lights hoping that would help. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The dealership service center Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No other symptoms.

I was driving on a 70mph hwy and traffic came to a full and sudden stop due to a car cutting across lanes a few cars ahead of me. There was no time for me to stop and I couldn’t see the traffic stopped. The car in front of me was able to stop without hitting anyone but I could not. Airbags did not deploy and this concerned me even though I was not injured.

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 was turning into a parking spot when my brakes suddenly felt loose, as if they had lost hydraulic pressure, and my vehicle accelerated into a wall. I had my vehicle serviced 3 weeks ago, and my brakes were fine. The day before the incident, I was coming to a stop, and the car was lurching forward as I was trying to stop. This isn't the first time the issue has occurred, and I had previously mentioned it to the dealership, but they found nothing upon checking. I was going to take it into the dealership, but I got into the accident.

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

The incident, occurring on [XXX], was first submitted by phone, followed by email to [XXX] on 27 May with incident description and sketch. I was given the Complaint ID no ODI11663050. However, now when I search for that number, nothing shows up! I have not received any information that the complaint has been investigated and dismissed! In order to publicize this event as much as possible to warn the public about this dangerous safety issue, I have posted the following on my X account ( [XXX] ) and have asked family and friends to spread the information as much as possible. Appreciate you contacting me at [XXX] and/or [XXX] about this. Post 1: 🚨Hybrid Car Warning! 🚨 If you drive a hybrid and get a Hybrid Motor Failure warning, STOP IMMEDIATELY and seek help! My 2022 Kia Niro Hybrid flashed this warning—I drove straight to an auto shop nearby. What happened next was terrifying… (🧵 1/3) Post 2: As I tried braking to park, the brakes failed, and the car accelerated instead! I barely avoided the shop, parked cars & trees—but I jumped a curb, went in & out of a ditch, and stopped across a major road. A red light saved me from being hit! 😨 (🧵 2/3) Post 3: The airbag deployed, hitting my chest hard. My chest is in pain. I had a major lumbar surgery in 2021 and my back is a mess ChatGPT indicates several possible causes, but the most relevant is a hybrid motor failure may cause unintended acceleration & brake issues. Post 4: Drivers, take these warnings seriously! 🚗⚠️ Stay safe! 🙏 #HybridCar #Safety INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2022 Kia Niro. The contact stated that the Hybrid Engine alarm activated and illuminated. The contact parked the vehicle for a few hours, and when restarting the vehicle, the alarm was no longer displayed. The contact continued to drive at approximately 5 mph. When pressing the brake pedal to park, the brake pedal floored with no resistance, and the vehicle began to accelerate. The contact immediately turned the vehicle towards the left to avoid crashing into a nearby building, jumped a curb into a ditch, causing the vehicle to bounce several times, and landed on the main street where it came to a stop. The air bags were deployed when the vehicle jumped the curb, landing in the ditch. The contact received bruises and cuts to their right leg and femur, chest, and back injuries. Medical attention was needed. The vehicle was damaged on the front end and was towed. It was not determined if the vehicle was totaled as of yet. A police report was filed. The dealer was not informed of the failure. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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.
