Recent owner complaints
- Seat belts
Installing a car seat and the belt buckle failed. The plastic part split and no longer holds the belt together. This was under regular pressure with standard leverage that the car seat design calls for. Nothing was ever on top of the buckle and it is not damaged in any other way at all other than the failure. They refused to replace it via warranty.
- Electrical system
Auto Hold/EPB lights come one while driving. Deactivates cruise control of on. Turns off auto hold. Ongoing issue with many reports but no recall or dealership knowledge. Ongoing issue since purchase.
- Service brakes
The "Auto Hold" feature on my Hyundai Ioniq malfunctioned, displaying a dashboard warning: "AUTO HOLD conditions not met. Press brake pedal." This message randomly appears while driving or stopping, and it deactivates the Auto Hold and Electronic Parking Brake (EPB) functions. In some cases, the car rolls after stopping because the system fails to hold the vehicle. This issue compromises vehicle safety, especially on inclines or during stop-and-go traffic. It puts me, passengers, and other drivers at risk. The problem has occurred multiple times and is unpredictable. It appears to be linked to a faulty brake switch or sensor, as noted in Hyundaiâs TSB 23-BR-001H. I discovered this issue…
- Vehicle speed control
During a highway trip that was bumper to bumper traffic at approximately 15mph, the car suddenly would not accelerate while operating on gasoline (not electric). The engine revs would increase to maximum without movement from the car (as if the car was in neutral). After checking the gear lever to make sure it was still in D, tried to accelerate again and engine rev high without movement. Eventually car came to stop with brakes, and the car could move on electric power (in hybrid mode), pulled over and turned off the car to visually inspect. After not identifying anything, turned on car and operation resumed to normal and would accelerate on gas power.
- Electrical system
The contact leased a 2021 Hyundai Ioniq Electric The contact stated that while the vehicle was parked, he attempted to open the driverâs side door using the key fob; however, the door would not open. The contact contacted Hyundai roadside assistance who assisted him in jumpstarting and recharging the batteries. The contact was still able to drive the vehicle. The contact stated that a couple of days later, the vehicle failed to start after several attempts. The vehicle was towed to the dealer where it was diagnosed that the mechanic switch that applied the emergency brake was not completely closed and kept the electrical circuit for the emergency brake activated causing the two batteries…
