November 2023: Purchase vehicle. September 2, 2024: Driving on highway 50-55mph in right lane. No one/nothing in front of me. Clear day. Vehicle collision alert starts beeping, vehicle abruptly brakes and steers itself into the left lane. I feared for my life and also for the person who was behind me. September 16-17, 2024: Drop off vehicle at dealership for oil change. Notfd service advisor of Sep 2 incident, requested investigation. Was told I'd have to pay for diagnostics and they would likely not find anything wrong. I was also told in summary: "nothing seemed wrong, incident could have been a glitch, we can talk about turning off the entire safety feature." -- I felt completely dismissed. Since early 2024 (shortly after purchasing): -?? vehicle randomly disables all safety features while I am driving. Yellow icons appear on my dash, and dinging noises keep alerting. This happens almost daily! I showed photos and videos to a second dealership, and sent them to Hyundai corporate (Dec 2024). No one has made any resolution for this. -?? noticing moisture build-up in window crevices. Rear windows have rolled down while vehicle was parked overnight on several occasions. November/December 2024: -?? vehicle making high pitch whistling noise. Problem diagnosed as cracked heater console. Sealed/repaired twice, in two different spots. Why wouldn't they just replace it?! -?? horn not working. I was unaware until dealership tested it. -?? rear doors barely opening. This is a serious safety hazard. People need to be able to get out (and in). Brought vehicle in, was told they "lubed it up", yet the doors are not opening fully again as of December 2024-January 2025. December 2024: -?? contacted corporate to file complaint. Since I filed in December 2024, which is 13 months after purchasing vehicle, I was told I don't qualify for Illinois lemon law buyback option. One month too late"! dangerous and annoying problems, and I'm stuck dealing with this" my vehicle is a death trap!

We lease 5 Hyundai 2024 Elantra Blue hybrids that were bought new a few months back. We have experienced the same issues with 3 of the 5 so far. Cars will STALL at low speeds and sometimes ENGINE LIGHT goes on. Cars will suddenly not accelerate after stopping at a stop sign. Extreme danger for our drivers who are transporting developmentally disabled clients to outings and shopping, etc. Hyundai REPLACED throttle body replacement but same issues reappeared 2 days after getting car back. Now, Hyundai is claiming the GPS units plugged in may be causing this, but other 2 are not experiencing this issue (2 of 5). They refuse to work on further unless GPS units are out, but customer needs GPS units per insurance. So we need help from Hyundai in dealing with the dealer Zimbrick East of Madison, WI. We need the vehicles, but don't want our employees at risk.

I received two emails from Hyundai Bluelink that "Vehicle battery level is below normal" late night 16 March 2024 shortly before midnight and several hours after I had parked my vehicle for the night. The car is less than two weeks old with less than 300 miles. After each email notice I checked my car and could not see any device or process which was drawing electrical power. By 10 am the next morning all electrical power to the car was gone and I needed a towing service to jump start my car. It appears the car battery spontaneously drained all its power through the night.
