During driving or while parked, the vehicle will shut off power brakes, and display an error "Stop Vehicle and Check Regenrative Brakes". When the power brakes shut off, the brake pedal location and feedback change sharply and the responsiveness is severely impaired. This error can occur at any time, which is very dangerous especially at highway speeds or when coming to a stop. I have let an authorized Kia dealership inspect the car for 31 days and did not see the issue. I took the vehicle back, and it happens frequently, so I drove it in with the issue active again and they have had it for another 7 days so far after seeing the issue actively reported. The first occurrence occurred at approximately 18000 miles, about 2.75 years of operation on May 12, 2022. since then, it occurs about twice per week. These trouble codes are asserted when this happens: C1360(81) Raw code: 536081 ECU: Adaptive cruise-control Status: Test failed, Confirmed, Warning indicator requested C1741(81) Raw code: 574181 ECU: Adaptive cruise-control Status: Test failed, Confirmed, Warning indicator requested C2405(27) Raw code: 640527 ECU: ABS control unit Status: Test failed, Confirmed, Warning indicator requested

Obnoxious eye and lung burning fumes in the car when turning the heater on. It was so from the day I bought it. Many owners have reported it also on Kia nitro forum. I drive in the cold without the heater or leave the window open to let the fumes out. It-€™s a health hazard and seems to relate to their heater core or it-€™s insulation material. Dealer and Kia claim nothing is wrong. It-€™s a health and safety hazard in need of immediate solution and recall. Also car-€™s steering column make a wheezing or rubbing noise when turning the wheel. Dealer says it-€™s normal. It-€™s not a safety hazard yet. But I have never driven or heard any other car with persistent rubbing noise it it-€™s inside the car-€™s steering column. Whatever is rubbing will eventually wear out posing failure and safety risk. A voluntary recall may be in order.

Received automated message that my engine may be compromised and to schedule maintenance, I took my car to the dealership service that same day. I was advised that the fuel injectors needed replaced, the car still was not working the was advised a cylinder needed to be replaced that did not correct the issues and was advised the engine needed to be replaced on my 2019 Kia Niro PHEV that has 17,801 miles. Dealership has my vehicle now for over 5 weeks With no estimated completion date.

For no apparent reason (other than a stress crack or other manufacturer or design defect), a long crack appeared in my windshield (start from the bottom left and going up and over about 20 inches). It is an interior window crack that cannot be felt from the inside or outside. Vehicle was simply parked at the time. Not caused by accident, rock or other impact. Dealer so far refused to replace the windshield under warranty although it is clear within the Basic Warranty Coverage and not excluded from coverage. Based on Google search, it appears that Kia has a long history of knowing about windshield cracks on different models, not just the Telluride which is part of class action lawsuit. Kia needs to be replacing cracked windshields like this per its Basic Warranty terms. It is a significant safety hazard.

1. steering wheel coupler makes a grinding noise when turning and getting louder every day. Dealer claims there is nothing wrong. 2. toxic nauseating ammonia type fume is emitted from the heater core when the heater is turned on. I have to open windows to be able to drive. Deeker claims nothing is wrong. Both problems reported by other Niro owner at Kia Niro forums.

The vehicle accelerated as if I had pressed on gas pedal when it came to a stop just before putting it in park gear. This is a safety issue, as it can hit someone or something. This happened at about 6400 miles and again at about 6600 miles. Both times it happened in my driveway, which is flat.

Pulling into my parking space, barely moving, car suddenly lunged forward and to the right over a concrete barrier and uphill. This happened with another Kia - forte- a few years ago. Same trajectory. Low speed turn, I did not accelerate.
