This happens frequently and has probably happened at least 6 or 7 times since I purchased the car last month. Digital warning alert appears on dash for no reason saying “Consider Taking a Break” even though i consistently keep my car in my lane. The warning is both distracting and annoying, and there is no way on this vehicle to turn it off.

I randomly get warning lights that my camera is disabled for Lane Departure Warning, Blind Spot Warning, Forward Collision warning, Lane Assist Warning. Each warning message I get comes one after the other stating CAMERA disabled. After a few minutes of driving, all the orange lights disappear and it seems to reset itself to normal. This has happened on three random occassions. I took it immediately to Hyundai of Bay Ridge but they said they were not able to duplicate the problem. I also mentioned to them that my dashboard and Infotainment system constantly dims then brightens for no reason whatsoever. Sometimes, it dims for two seconds, then goes bright again, sometimes it dims for much longer. This happens everyday and it doesnt matter if it is a bright sunny afternoon or an early morning. It constantly dims then brightens. The dealer keeps saying they can't find anything wrong because diagnostics shows everything is ok with their computer. I feel like they are simply sweeping this under the rug because it is a leased vehicle and I am concerned for my safety should I suddenly lose power.

The Gas pedal, would not work as I was trying to accelerate when going from the ramp onto the freeway. The pedal had no pump in it, it just went all the way down as I was trying to press and the car started slowing down. I had to pull over on the side of the freeway and restart the car for the pedal to start working again. I came to the dealership the next day on 12/5/25, at around 5:45pm in which I was scheduled to come back at 8am on 12/6/25. My safety was at risk, because the car lost pedal power for me to pickup speed as I merged onto the freeway. I brought it in for inspection, at the dealership I purchased it from. There were not any signals or displays that came on during the incident.

When I am using cruise control, my car will just randomly slam on its breaks. I have taken my car into the dealer multiple times, and they have written it off everytime. They have said it’s “direct sunlight” yet I can prove it’s not happening in the sunlight. It happened again today when it was cloudy. It’s also happened before the sun came up in the morning. I have even filed a case with Hyundai directly, and they said if they can’t get it to mimic it, then they can’t do anything about it. But it’s so random, sometimes it happens 50 miles from home, other times it’s 300 miles from home. Always willing to let anyone inspect my vehicle to help solve this issue. I’ve been taking it to my dealer for a full year until I found out I needed to come put it here. It’s random, it won’t happen in the same spot twice. But every time it’s done it, there is never a vehicle in front of me. My assumption is there is a defect with the adaptive cruise control. I’ve talked with Hyundai and they claim they’ve never heard of this happening to anyone, yet when I google it, there are MULTIPLE forums with people stating this exact thing is happening to them. SAFETY issue is it slams on the brakes so hard I’ll go from 80 to 65 before I can get the cruise control off. If someone is behind me when it does this, they will slam into me.when I’m dropping 15 mph quickly, that vehicle behind me will hit me like I’m a stopped object. No warning lights before it happens. This has been happening since I bought my vehicle at 0moled to now where I have 34k miles

While it may sound bizarre, I can definitively demonstrate that whenever I am present inside a car, the car become very unstable and bouncy and unsafe to operate. Not only does it not steer straight the car also becomes incapable of coasting smoothly and is constantly racing or aggressively slowing down. I can’t be the only anomaly and whatever is causing this could be widespread and is certainly dangerous. I have found it to occur only with the cars which I am inside. I would like to demonstrate this in person if possible to an investigator.

This is a repeat incident. While driving, the speedometer stops working, tachometer, all of the collision warning systems start going through a self test, the check engine light comes on, and most concerning is the power steering. It becomes heavy, as if it is working at half power. The dealer kept the car for over a week recently, and they said that they were unable to duplicate the issue. It happened again while I was on a road trip , and I stopped by five star Hyundai in Albany ga. The service advisor was aware of similar issues have occurred on Hyundai's, but that they were too busy to look at it. She wouldn't even come out of the building to look at the car and wasn't interested in looking at my video. I tried to upload video to this form, but was unable to do so

Towards the end of January, my car computer was reset because the car was telling me that I needed an oil change early and the dealership told me it could just be a computer issue. I then took my car to get an oil change and full vehicle inspection on February 24th, 2 days after that on the 26th I was leaving my school parking lot when the vehicle accelerated awkwardly when I was leaving out of a parking spot, I was then able to gain control back over the speed until the vehicle again abruptly accelerated and jerked to the left sending my car over a curb, deploying the air bag, and completely totaling out the vehicle.

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!
