NHTSA Complaint #11459087 — 2021 HYUNDAI PALISADE

On my way to work on the interstate with the cruise control set at 80mph a few weeks ago, the cruise control turned off automatically and all the warning lights came on within the dash. I pulled over, but the car seemed to be running fine otherwise. For the next few days the lights would be on or off and sometimes cruise control work and sometimes it didn't. I also noticed the parking break would engage automatically almost with every time I stop, which was also rare. I took the vehicle in for service and they were perplexed by the situation and had me leave my car for a few days. They thought they had it all fixed, but when I picked it up, within 24 hours, the lights came on again. I had noticed some break pressure issues when starting car up with this issue, but never a huge concern, until I backed out of my girlfriends driveway down a hill within 30 seconds of starting the car. With my foot on the pedal, the break disengaged for 2-3 seconds as I drifted down towards the street in reverse, and the ABS starting pumping until I was able to depress the brake and get the car to stop (probably drifted 10-15 feet). Thank goodness no one behind me. I drove the vehicle in for service immediately as they suggested if lights remained on, so they could run diagnostics. They ordered a wheel sensor, which took a few weeks to get in while I still drove the vehicle with the ABS causing me some concern over those 2-3 weeks. Just yesterday before my service to get wheel sensor changed today, I was out picking up food and driving through a flat parking lot within 30 seconds of starting the vehicle. The same issue with ABS happened that I had before and I started going through a stop sign and pedestrian walkway. Luckily no one coming and brakes kicked in again after 5 feet of having no brake control at low speed. Wheel sensor replaced today and lights off. Everything seems to be working. I'm extremely concerned about this safety issue and potential accidents, injuries, deaths!
