the electrical system

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.

VEHICLE SPEED CONTROL

1 injured · crash · towed

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

UNKNOWN OR OTHER
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

POWER TRAIN
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

ENGINE
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.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
