Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Crash reported
When the engine is turned off, and the car is not in park, it rolls. When the engine is turned off the car should automatically switch to P to prevent it from rolling. Our car was left in R with the engine off. And instead of switching to P automatically, it just rolled away and hit the neighbors garage.

I leased the vehicle in 03-2021 and within the first year took the car back to the dealer 3 times for complaint on braking system. The brake pedal would loose pressure and stopping distance would extend further than anticipated. the dealer consistently told me that they could not duplicate the problem. now has gotten to the point that EBP light and HOLD light stay on steady and red Brake light flashes, due to this the smart cruise control and crash avoidance system become inoperable. Recently became aware that this issue is known to Hyundai and they have TSB for this issue, TSB # 23-BR-001H which describes the problem with rear caliper harness contamination with moisture. now that my vehicle has passed the 36K miles warranty, dealer wants to charge about $2000 for repairs. Currently have 39685 miles on the vehicle.

The display does not always show reverse camera when backing up. Not often, but does occur. I can use mirrors, etc. Annoying as it is a learned experience with this car, and when reverse camera is not operational it does limit view behind car due to design. I did capture video this time as it isn't first occurrence. I was in parking lot where I could do this without endangering anyone.

I WAS DRIVING ON A 6 LANE RD., NEARING AN INTERSECTION. I WAS IN THE MIDDLE LANE, TRAFFIC ON BOTH SIDES OF ME. WHEN I APPLIED THE BRAKES TO STOP THE CAR, MY BRAKES FAILED. I ENDED UP HITTING THE CAR IN FRONT OF ME. I WAS LUCKY THAT WE WERE ALL DRIVING AT A VERY SLOW SPEED AN I DID NOT HAVE SERIOUS INJURIES, JUST ONE WEEK OF NECK AND BACK PAIN. THE BRAKES FAILING HAPPENED ONCE BEFORE. MY DAUGHTER WAS AT AN INTERSECTION WITH NO TRAFFIC. THE LIGHT CHANGED TO YELLOW. WHEN SHE TRIED TO APPLY THE BRAKES, THEY FAILED AND SHE HAD TO GO THROUGH THE YELLOW LIGHT. WHEN SHE TRIED OUT THE BRAKES AFTER THAT, THEY WORKED AGAIN. THE CAR HAS ONLY 973 MILES ON IT. WE HAD IT ONLY FOR 6 WEEKS AS A NEW VEHICLE. THE ACCIDENT HAPPENED ON JULY 15. HYUNDAI CALIFORNIA HEADQUARTERS CALLED US ON THE 20TH OF JULY. THEY CLAIMED, WE HAD CONTACTED THEM, WHICH IS NOT TRUE.THEY REQUESTED THAT NOTHING BE DONE ON THE CAR UNTIL THEY HAD A CHANCE TO INSPECT THE CAR. YESTERDAY (8/12/20) THEY TOLD US THAT IT WOULD TAKE 6 TO 8 WEEKS TO REPAIR THE CAR. THIS IS FISHY, THE CAR WA IN THE CHICAGO AUTO SHOW AND ENDED UP AT OUR DEALER. I BELIEVE THEY SOLD US A BETA MODEL. BUT THEY WILL NOT ADMIT TO ANYTHING. WE HAVE NEVER HAD HEADQUARTERS OF ANY CAR MANUFACTURER GETTING INVOLVED AFTER AN ACCIDENT. MONDAY OUR CAR RENTAL PAYN=MENT BY OUR INSURANCE COMPANY WILL END AND WE WILL NOT HAVE A CAR AVAILABLE. SO FAR HYUNDAI DOES NOT SEEM TO CARE.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
