2019 Kia Niro. While driving normally on the street, the driver attempted to brake & the brakes would not respond. This is a very scary situation and Kia needs to handle immediately!! The message "Stop the Vehicle and Check Regenerative Brakes" was displayed. Thankfully the driver was able to come to a stop without crashing but if this was during heavy traffic time it definitely would've resulted in a crash. Could be even that much worse on the freeway, especially in Los Angeles. The vehicle was towed to the drivers home. After checking again, the vehicle was in limp mode & would not go over 15mph. The driver was able to get it to a Kia shop to be checked & they quoted a $9,000 repair!! This is horrible that Kia is allowing this issue to go on!!!

Pedestrian alert sounds
the federal safety agency 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 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, the federal safety agency 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 the federal safety agency 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 the federal safety agency regarding the subject matter of the petition.

What 2019 Kia Niro owners say
Most recent owner complaints, unedited.
While traveling from upstate New York, the vehicle displayed an engine overheating warning shortly after startup while the engine was still cold. Because I was away from home, I stayed overnight and the next morning took the vehicle to a Kia dealership for inspection. The dealership inspected the vehicle and diagnosed a problem with the exhaust heat recovery system pipe. According to the service department, coolant is leaking internally through this component and is being burned in the exhaust system. The cooling system was pressure tested and held pressure externally, indicating the coolant loss is occurring internally through the exhaust heat recovery system rather than from an external leak. This condition can cause coolant loss and overheating while driving. If the engine overheats while the vehicle is in operation, it could create a safety risk due to sudden loss of power or engine damage. The dealership confirmed the diagnosis after inspection and testing and provided a repair estimate to replace the affected exhaust heat recovery system component. The overheating warning message was the first symptom observed prior to diagnosis. The problem was confirmed by the dealership after inspection and testing. This issue may indicate a defect in the exhaust heat recovery or thermal management system used in this hybrid vehicle, as coolant is entering the exhaust stream internally rather than leaking externally. If this type of failure occurs in other vehicles, it could lead to overheating while driving and potential engine damage.
Hydraulic fluid is leaking onto the hydraulic clutch actuator’s circuit board, creating a potential fire hazard. The vehicle requires replacement of the dual clutch and slave cylinder. This failure occurred just over one year after Kia replaced the dual clutch and performed a full engine replacement at a Kia dealership. This condition is identical to a known safety recall affecting 2019–2022 Kia Niro vehicles involving hydraulic clutch fluid leaking onto the actuator circuit board and creating a fire risk. Although my VIN is not listed under the recall, the vehicle is the same year, make, model, and drivetrain and is exhibiting the same defect described in the recall. This appears to be a recurring safety defect involving the hydraulic clutch system.
Continuing and worsening motor rumbling noise and ticking/clicking at slow speeds. Spent a couple of months and without car for weeks just to have kia confirm and have gearbox changed. This has existed in some form for a couple years now.

Car has warning message and several engine lights on dash come up and asks to stop car and check the regenerative brake system. Car loses all systems that are electrical, car is very hard to drive, even not operative. This has happened many times over the past four years. Each time the car has been taken to a authorized KIA Dealership and they have not been able to fix the problem. It happened almost a week ago and dealership told us that they couldn't find anything wrong and were told to pick it up. Happened again today and it was while driving. Same issue, same warnings on dash.
Car caught fire
KIA NIRO 2019 SAFETY RECALL As described in the safety recall (previous page), my KIA Niro 2019 alarm went off with the following error message "Engine Overheating". Kia of America and its dealership refused to fix the problem. The car dealership -said- has no direction as to how or when to fix the problem, and the KIA consumer hotline is out of business.
I’ve had this repaired by Kia and immediately failed again, but a component to the alternator and ac unit is attached to the drive train and will cause an alarm that hybrid battery failure and sudden power loss(they told me this with the first “fix” but failed within an hour of leaving Kia. It’s happened again tonight and nearly caused a crash on the freeway and I’ve seen many others with this issue and I want to drive my kid home safely so any help would be wonderful with this issue. Thank you!!
