Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

DP22005ClosedDefect Petition

Pedestrian alert sounds

Opened Jan 27, 2023
Closed Aug 7, 2023

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.

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.

Crash reported1 injury reported

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.

I received important safety recall letter for NHTSA recall # 23V534. the HCA & or Fuse might need to be replaced . I brought the 2021 Nero to my local Kia dealership, Eagle kia ,Riverhead NY on January 18th. The dealership still has the vehicle & claims that a code came up when they did the diagnostics That requires a part that must be secured to complete the fix for the recall. they claim they are awaiting approval from kia corporate & NHTSA to add to the technical bulletin. But their is no timeframe they have or when this additional part will be available. The dealership has the fuses & Harness for the HCA replacement, but needs this additional part. I asked what the # of this part is or name, but all they would tell me TBT.

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 PREVENTION: WARNINGS

PITSTOP: TECHNICAL OPERATIONS: EXTERNAL DAMAGE TO ULTRASONIC SENSOR: This Pitstop provides information related to Parking Distance Warning (PDW) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle (ultrasonic sensor) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a “Warning Lamp’ to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. (Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.)
