While driving on the highway at 70 mph, cruise control engaged, there was a sudden loss of drive power. I could not accelerate, or return to the cruising speed. The speed just dramatically fell. The only remedy was to pull over to the side of the road, turn off the car, and start it again. This VIN was not included in the initial similar recall earlier this year.

On February 3, 2026, while driving in a high-traffic turning lane, my Hyundai Kona Electric vehicle suddenly lost propulsion and would not accelerate. The vehicle shut down without warning and could not be restarted. Traffic was building behind me, creating a safety hazard. I felt unsafe due to surrounding vehicles expecting movement, I contacted the police for assistance. The vehicle had to be towed from the roadway. The vehicle was transferred between 3 dealerships before being diagonsed. On February 16, 2026, the issue was diagnosed as a motor position sensor failure affecting the propulsion system. The vehicle has remained inoperable since February 3, 2026, and there is no repair ETA due to parts availability. The vehicle remains at the servicing dealership and is available for inspection upon request. There were no prior warning lamps, dashboard messages, or noticeable symptoms before the sudden loss of propulsion. This incident involved a sudden failure of the vehicle’s propulsion system while operating in active traffic and presented a significant safety concern.

After powering on the car, the dashboard displayed multiple brake system warnings, including the brake system warning light and a message on the LCD display that read "Check regenerative brakes." A Hyundai dealer replaced the integrated electric brake unit assembly (invoice attached).

My wife's car t-boned another vehicle, but the air bags didn't deploy. Luckily, she wasn't hurt badly, but the vehicle was deemed a total loss, so you can imagine the force of the collision. The forward collision warning and automatic emergency braking didn't activate either. I reported it to Hyundai. They sent an inspector to examine the vehicle, and I also showed them photos and a copy of the police report, but they claim that my car was hit on the side, and the pre collision system doesn't detect imminent side impact. That's completely outrageous. I don't know what their inspector wrote in their report, but the photos and police report are irrefutable proof that my wife had a frontal collision with the side of another vehicle. Hyundai kept denying it because they didn't want to help financially. I attached a copy of their determination letters (the second one was after I submitted a copy of the police report to prove that my wife's car is the one that hit the other vehicle, but Hyundai refused to see it as it happened).

Hyundia has had my car in for the SAME recall 4 to 5 times . 6 total weeks this time around. The ""refill inverter coolant" light kept coming back on . The last time I got it home it had more issues than when I took it in and wouldn't even catch a charge . (EV) They fried my compassitor trying to fix the inverter coolant recall . I then took had to pay 450 for a diagnostic ' (Kerry hyundai alexandria) They said electric motor is bad and will cost 8000 to 9000. Got a 2nd diagnostic (Jeff wyler hyundai cincinnati) Completely different result- Zero mention of motor ' said Ac compasitor failed. (Had no issues prior to them working on the original recall ) The light for the recall is still on by the way and they want me to pay 3500 for new AC capacitor . (600 diagnostic included in that price ) " The dealership’s failure to properly perform the inverter coolant refill recall directly caused the AC compressor failure in my 2021 Hyundai Kona EV. Before taking the vehicle in for the recall, the AC system was fully functional, delivering cold air without any issues, and the car experienced no charging problems, indicating the battery and cooling systems were operating normally. The recall, intended to flush the inverter cooling system and replace the crystallizing BSC-1 coolant with BSC-2, was not completed correctly, as evidenced by the dealership’s admission that they couldn’t fix it. This botched service likely left air or debris in the cooling system, which, in Kona EVs with a heat pump, could overwork the AC compressor used for battery cooling during charging. The compressor’s failure shortly after the recall service, despite no prior issues, strongly suggests that the improper coolant flush caused undue stress on the compressor, leading to its $3,000 failure, which should be covered under warranty or as a goodwill repair due to the dealership’s error".
