I own a 2021 Kia Niro. The rear backup camera intermittently fails to operate. When shifting into reverse, the display screen will either go completely black or the camera will not activate at all. This issue occurs unpredictably and without warning. As a result, I am unable to see behind the vehicle when reversing, which creates a significant safety concern. The lack of rear visibility increases the risk of a collision, especially in areas with pedestrians, children, or low-visibility obstacles. I am aware that similar rearview camera failures have led to recalls for certain Kia Niro EV models; however, my vehicle is not included in those recalls. Despite this, my vehicle is experiencing the same or a very similar issue. The problem has occurred multiple times from 2023-now and does not appear to be related to specific weather, lighting, or driving conditions. This defect poses a serious safety risk and should be investigated for potential inclusion in a broader recall.

This is a hybrid vehicle. It has Dual clutch transmission. Since I have owned it, intermittently the clutch does not disengage completely. This causes the vehicle to try to pull ahead but my foot is on the brake. The vehicle does not stall. Somehow it figures out it can't pull ahead and somehow fully releases. I have brought it to kia at least 3 times. In each case they tell me they cNt get the car to fail and since there are no codes produced they can't fix it. They even held onto the car several days. I asked them to please replace SOMETHING but the say Kia policy will not allow them to do that. So I am stuck with a car that keeps misbehaving. It is embarrassing because problems occur while a passenger is in the car and it seems to them that I am not driving correctly. I don't know what to do.

EV motor and drive train have a clattering noise, much like a playing card attached to a bicycle clattering against the wheel spokes. it speeds up and slows down with the acceleration of the motor.

Service BrakesMay 2025 · ODI 11663437Details +Close −
The rear brake rotors on the vehicle are pitted, as confirmed by a local repair shop. The "incident" is ongoing. Kia refuses to repair or replace them under warranty (25,500 miles on the car), claiming they are wear item. However, pitting is not wear, in fact quite the opposite. My analysis (30+ yrs in the auto business): As an EV, regenerative braking means the actual brake systems are rarely used. Noise at low speeds prompted the inspection at a local shop. Braking under high speeds does not result in noise, telling me the system relies too heavily on the front brakes. The result is the rear rotors are too often unused leaving them to rust and then pit. Tesla recognizes that regen braking can actually harm brake rotors, suggesting burnishing the brakes at times using the following procedure: 1) Drive the vehicle at approximately 50 mph - 55 mph (80 km/h - 90 km/h) on a straight road. 2) Apply moderate, consistent pressure to the brake pedal to slowly decelerate the vehicle, releasing at 10 mph (15 km/h). 3) Repeat this procedure 6 times, waiting at least 30 seconds between applications. Since the rear brakes do not appear to engage on the Kia Niro, this method is fruitless. Other Niro drivers report this as seen here: [XXX] I my opinion, the vehicles should at minimum be repaired under warranty or recalled to "rebalance" the brake system. Thank you...

Vehicle Speed ControlJul 2024 · ODI 11600985 · crash · 1 injuriesDetails +Close −
I was backing out of a tandem parking spot in a private garage and got too close to a pillar, and tried to pull forward into the spot. It felt like the car got snagged on the pillar, but while pulling forward slowly, the gas pedal snapped off and the car accelerated quickly and uncontrollably. I was able to avoid hitting other cars but drove straight into a concrete wall despite immediately braking. I'm relatively uninjured, but if it had happened in a less controlled environment and/or I hadn't reacted as quickly, there could have been serious injuries to myself or others. There was no indication of an issue prior, and the car is currently in storage with my insurance company and will be appraised next week. I have photos of the broken pedal.

Vehicle is available for inspection upon request. HEV light lit up on dashboard and a warning message was displayed alerting me to immediately pull over and turn off the vehicle. At the same time the vehicle was not responding and acceleration became troubling and with marked hesitation. After waiting several minutes I attemped to turn the vehicle on again but the warning light and alarm went off. Vehicle is currently at the dealership but they have not offer a solution or even a temporary remedy.

While driving on a major highway, my sunroof suddenly exploded. Luckily the screen was pulled shut otherwise I would have been covered in glass. I was able to drive to the next exit and park the vehicle to then get out and observe the damage. There was a gaping hole in the sunroof. I called a tow who brought me to a Kia dealership. I explained what happened and after inspecting the car the dealership told me it was road debris that caused the issue. I did not see or hear anything hit my car prior to the explosion of the sunroof and I question their findings that it was debris related.

Back Over PreventionJul 2021 · ODI 11427104Details +Close −
I'm a new Niro Ev driver. The VESS noise when reversing the vehicle is very loud. It is too loud, I live in close proximity to neighbors and have to get up early for work and the sound is a major nuisance, I would not want a neighbor that has this car . I understand VESS in place for safety but the reverse backup beeping is just a step down from a garbage truck backing up, especially in the silence of a residential neighborhood in the early AM hours. Furthermore, I and others as seen on web forums will reverse faster than we normally would do to be able to take the car out of reverse as quickly as possible to stop the blaring beeping. This creates its own risk, as if there is less time to react if there is a pedestrian behind the vehicle. The volume of the noise should be greatly reduced. It is also unnecessary noise pollution. Kia, please fix this.

Visibility/WiperJul 2021 · ODI 11423414Details +Close −
There is a silver strip of "trim" running completely across the dashboard just above the radio controls. It is so reflective that a glare occurs periodically throughout the day when the sun hits it. It's so bad that it blocks the left side mirror with the reflection and can even blind the driver. This needs to be addressed by Kia. Easy solution is to have Kia remove the strips, paint them black, and re-install them.

Investigations
1 NHTSA investigation on record
Investigations are agency reviews, not findings that a vehicle is defective.
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
