2025 Hyundai IONIQ 5: complaints, problems and recalls

These cars still have problems keeping the 12v charged. Car was leased on Jan 19. 12v first died on Feb 15, took it to dealer where they trickle charged it. 12v died again on Feb 18, dealer replaced the 12v. The 12v died again on Mar 11 and is still at dealer service center. Case with Hyundai corporate was opened and the dealer is going back and forth with them. When car is left alone for 5 days, the 12v appears as needing a replacement, so there is something wrong with the system that keeps the 12v charged or there is some parasitic drain some…

The Forward Attention Warning system in the refreshed 2025 Ioniq 5 gives constant false positives for both my wife and myself when we are driving the car. With Hyundai's HDA and lane keep active, the system keeps chiming, claiming that the driver is not looking at the road when we are. In fact, the calibration is so poor that it is a safety issue. The constant random warnings are very distracting, and sometimes the system does not recapture your eyes before timing out and hard braking the car on the highway. This is really unacceptable and …

I purchased this vehicle on [XXX] in the state of Colorado and had to drive it home through a winter storm to California. While driving home the vehicle on multiple occasion the vehicle flagged driver assist disabled or inoperable errors due to "radar blocked" stopping and checking the front of the vehicle I found that the car had no snow or ice build up on the exterior of the bumper, and there was no reason that all the driver assist and even safety features like Automatic Emergency Braking had been disabled. In addition while making this dr…

This car has a system called Forward Attention Warning (FAW) which monitors the driver's eyes using an in-cabin infra-red camera trained on the driver. When smart cruise control and lane following assist are both activated, FAW is forced ON by the car. If FAW thinks that the driver's eyes aren't on the road, it beeps, puts alerts on the panel visible to the driver and turns off all driving assist features. The problem I'm reporting is that the FAW system is completely broken. Even though I'm looking straight forward, it says I'm not paying a…

I purchased this car this week. The vehicle is equipped with a safety feature called Forward Attention Warning (FAW). Its purpose is to monitor the drivers attention (eyes??) and trigger an alert when the drivers attention is distracted for a period of time. I took it for the first time on a 150 mile trip. During the trip, the FAW alarm was triggered constantly. I tried changing my head position, taking my glasses on/off, changing my hands holding the wheel, etc. Nothing seemed to matter. It is not only a nuisance, but it causes other au…

The high-voltage traction battery on my 2025 Hyundai Ioniq 5 Limited RWD failed unexpectedly around [XXX], when the vehicle had approximately 1,250 miles on it and was just over 3 months old. The car had been parked in my driveway with about 80% charge while I was away for several days. When I attempted to drive it, the vehicle would not shift out of neutral. No warning lamps or error messages were displayed before the failure. The vehicle was towed to Van Hyundai in Carrollton, TX on April 3. While loading it onto the tow truck, the 12V batte…

With Adaptive Cruise control and Lane Keeping Assist on, no matter how attentive I am, within a couple minutes (give or take) I get Driver Attention warnings. These warnings are distracting and require manual intervention in traffic. I can stop them either by turning cruise control on and off, or by accelerating manually, which can be dangerous and/or inconvenient. I do sit high in the seat, as I have a long back. I wear no glasses. I have normal wide open eyes. I am keeping my hands at 10-2 orientation. I am sitting in a way that gives me clea…
