Driver Assist & Collision Avoidance complaints by model year
My 2024 Kia Niro Hybrid has experienced multiple issues that I believe should be documented. The vehicle previously displayed an Electronic Parking Brake (EPB) warning. It was taken to an authorized Kia dealership for diagnosis and repair. Although repairs were performed for the EPB-related issue, I am submitting this report so the condition is documented if similar reports are being received from other owners. In addition, the vehicle developed a persistent creaking/clicking noise during forward driving. The noise was not present when the vehicle was new and began after normal use. It is most noticeable during forward driving and is not heard while backing up. The vehicle has been inspected by an authorized Kia dealership on multiple occasions, including a ride-along with a technician. After evaluating the vehicle, the dealership advised that the noise was normal and that the vehicle was functioning as intended. No additional repair was recommended. Although the dealership concluded the noise is normal, I remain concerned because the noise did not exist when the vehicle was new and has persisted. I am submitting this complaint so NHTSA has a record of the issue and can determine whether other owners are reporting similar conditions that may warrant further review.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
This submission is supplemental information for my prior NHTSA complaint (Complaint #XXX). After filing the original report, I learned additional details from the Kia dealership that serviced my vehicle. The service department stated that they have seen the same electronic parking brake controller and actuator failure on multiple Kia Niro vehicles from model years 2018–2021. They reported that these failures were not covered under warranty for those years, even when the symptoms began during the warranty period. The dealer also explained that Kia made design improvements to the electronic parking brake system in later model years and expanded warranty coverage for the updated EPB assembly and control components. This suggests that Kia was aware of recurring issues with the earlier design, despite no formal recall or service campaign being issued for the affected 2018–2021 vehicles. I am submitting this supplemental information because it indicates a potential pattern of safety‑related failures involving the electronic parking brake system across multiple vehicles and model years. These failures affect the vehicle’s ability to hold position when parked and may interact with braking and stability control systems.”

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The electronic parking brake controller failed after intermittent warnings that began while the vehicle was still under warranty. The parking brake actuator also failed and had to be replaced. The electronic parking brake system is part of the vehicle’s safety system, and the failure caused the parking brake to malfunction unpredictably. The issue did not store persistent diagnostic codes, making it difficult to diagnose earlier. This is a safety concern because it affects the vehicle’s ability to hold position when parked and can interfere with braking and stability control. Because I am not the original owner, Kia refused to perform this as a warranty repair even though the intermittent failures began while the vehicle was under warranty.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I was travelling on a road today and was in the right hand lane with adaptive cruise control on. I then switched lanes to the left hand lane (it's only 2 lanes) and the adaptive cruise control was still on. I noticed the car travelling faster than it should be for there being a stopped vehicle ahead. I was prepared to stop on the brakes and luckily I was! The collision warning came on and I immediately applied the brakes. How is it that the collision warning came on before adaptive cruise control came on? This is at least the 3rd time something like this has happened.

Problem 1, Check Engine Light: I purchased the used car on Jan 9 2025, around 23,400 miles from Kia Dealership, capitol Expy in San Jose. Today 05/27/2026, the odometer reads 26, 407 miles. My car is used only twice a week - 20 miles on Fridays, 12 miles on Wednesdays. My car has less than minimum wear and tear and is barely used. I completed my 25K service after Thanksgiving in Nov 2025. I have not even driven 1500 miles and the car is back in for service. Prior to this, within a month of purchasing my car Kia replaced the battery in my car. Around Mar 15, 2026, the Check Engine Light displayed. I called the Kia Dealership on Capitol Expy in San Jose 3-4 times, but they Kia dealership don't call back. On 05/15/2026, for the first time I drove about 50 miles return trip. While driving North on I-280 from [XXX] to [XXX] , over rolling hills that had some incline, the Check Engine Light came on.I scheduled service. I experienced that the vehicle struggle to climb the incline of rolling hills, after the battery charge was exhausted and the engine was running only on gas. The gas was 3/4 full. This is a safety hazard for me to be interrupted by Check Engine Light twice while driving and that too when my car has not even completed 30K miles. My car is sin Service on 05/26/2026 and in the shop for 3 days diagnosis. The Kia Dealership has yet to determine the problem. I have had to rent my own rental car even though I purchased Extended Warranty on the car. Problem 2, Blind Spot Warning Light on right side mirror: On 05/13/2026 and on 05/22/2026, the Blind Spot warning light on right side mirror does not display oncoming traffic when my car is parallel to the lane markings. On 05/13/2026, I was driving at 30mph and on 05/22/2026 I was stationary in the center divider. In both instances, the passing driver had to honk at me really loud -- to avert an accident. Both problems are severe safety hazards. 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 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 open recall, 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.

My backup camera works intermittently, it has been tested at the dealership and supposed to be faulty, but if faulty why does it sometimes work, this causes danger when reversing the vehicle! The dealership wants $821 to replace the camera, I feel it should be a recall, as a whole bunch of Ford vehicles are recalled for the same issue! I have had several close calls even using my mirrors and looking over my shoulder, as the car has big blind spots!

NHTSA complaint #11695034 — an unverified report by a vehicle owner.
Forward collision system fully activated while driving eastbound in the fast lane on [XXX] . The sun was behind me. No glare. No cars or objects were in front of me or next to me. The dashboard started flashing and warning sounds activated and the car slammed on the brakes itself. The seatbelt locked up and left me bruised. Miraculously, the cars behind me avoided crashing into me while I accelerated out of it. I could have been killed. Dealership minimized my concerns. I don’t want to drive this car ever again unless someone can make sure it doesn’t happen again. This safety feature malfunctioning is a death trap.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I am reporting a serious safety concern regarding the 2025 Kia Niro Hybrid and its adaptive cruise control system. When the cruise control is activated and set to maintain a certain speed, the vehicle continues at that speed regardless of whether there are other vehicles in front of it. In multiple instances, the car approached slower-moving vehicles at 45 mph without reducing speed or giving any warnings. There was no automatic braking or even a prompt to alert the driver of the imminent danger. This is extremely dangerous and could easily result in a rear-end collision if the driver is not fully alert. It is especially surprising because the same vehicle features intelligent climate control functions—such as adjusting fan speed during phone calls and preventing windshield washer fluid odors from entering the cabin while the A/C is running. Given the level of attention to such minor details, the lack of basic forward collision mitigation behavior is unacceptable. The issue was reported to a Kia service center, but no clear explanation or resolution was provided. I believe this may be a software bug or a design oversight that has not been properly acknowledged. Recommendation to other drivers: always keep your eyes on the road and be ready to intervene, even if the adaptive cruise system is engaged. The risk of collision is high if you rely on the system to slow down for vehicles ahead. This needs to be investigated immediately before it leads to serious accidents. I urge the NHTSA to review this issue and, if necessary, request a recall or software update from the manufacturer.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Driving VA Interstate 64. Traveling right side travel lane approximately 70 mph. Had ADAS engaged. Car entering highway, moved to center travel lane to pass. As I approached entering highway car, suddenly, my car stalled, engine off and I was stopped in center travel lane. Able to start car by putting transmission in park and pressing start button. Called KIA Car Care Center - They have no record of this type situation occurring throughout country. Took car to dealer. Their Technology Service Rep checked whole system and found no problems including memory bank listing the stall/stoppage incident. I will go to dealer and ask for their report. 2nd incident. Happened within first month or ownership 10/23. I dismissed incident as something I must have done due to my lack of familiarity with new technology.

My wife was in an accident on [XXX] around [XXX] at the intersection of [XXX] . She had exchanged safety information with the person whose vehicle had stalled. She went to shut off the car upon exchanging the information and after pressing the ignition button the vehicle began to roll. She was outside of the vehicle when she had pressed the ignition button. She tried physically to stop the vehicle, trippped and was dragged until the vehicle came to a stop after running over her leg and hitting a tree. The vehicle had recall items addressed on October 2 or 3rd. She was trying to stop the vehicle from rolling as she knew that school was letting out and a school bus would be coming on the road she was at. I contacted the dealer about it and they stated that they had never heard of this happening with there vehicles and to call customer service. The police officer verified verbally that the vehicle was in park when he checked on the condition of my wife who sustained serious injuries on her left leg and was hospitalized for surgery and wound treatment. This is the first time that we ever had an issue with the vehicle. It started when the vehicle in front of her had stalled and backed into her (although his story changed after the injury to my wife).
