There are 6 owner-reported driver assist & adas complaints for the 2022 Hyundai Ioniq 5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
ABS or All wheel Drive did not seem to work while driving on a Highway, and I tried to stop as there was another vehicle on the road which was spinning out of control. If ABS was activated, the car would have stopped, and similarly if All wheel Drive was working, car would not have spun out of control.
Forward safety system error message on dashboard. Dealer found DTC codes below ADAS_DRV ADAS Driving ECU C28B186 CAN Signal Error FR_RDR FR_RADAR Front Radar C162078 Alignment failed Dealer states alignment failing not covered under warranty even though no damage visible on vehicle. Unable to afford repairs if not covered under warranty. Radar is clearly faulty as there is no damage to vehicle.
ICCU stopped charging my auxiliary battery (Hyundai Ioniq 5). I couldn’t figure out why, but I began carrying a portable charger with me which instantly got my car going again. One day during a particularly nasty snow storm, my battery was dead again and I jump started my car. I drove it about 40 feet before I realized it needed snow socks. I stepped out of my car and got back in and a whole myriad of warnings were going on. I got a code for the vent flaps (snow had got stuck in there…that was an easy fix. Also my Auto Hold light, Check ABS light, and Smart Cruise Control warning indicator lights were all on and are still two months later still not working. The car otherwise operates well enough to drive as I replaced the auxiliary battery. Since replacing the battery, the car operates as well as the ICCU (it charges the new battery) but the previous issues remain.
The cruise will shut off randomly saying the radar is blocked. When it does this the car decelerates very fast. Which is very dangerous in traffic. I’ve almost been rear ended a few times. It has also just started decelerating very fast when in cruise on highway for no apparent reason with no one in front of me.
When driving on the interstate the collision avoidance system will falsely trigger around 5% of the times going under overpasses or road signs. The vehicle rapidly decelerates using regenerative braking.
Involved in a minor collision. Rear ended another car accelerating from a stop light (low speed). Forward collision warning did not activate. Auto braking did not activate. No airbag deployed.
