“On July 15th I was driving away from work and my car suddenly stopped accelerating. I was able to get it towed to a body shop I previously had it repaired at. They said the battery system was blowing a fuse when it would become undrivable. They took it to the local Hyundai dealership where they applied a new software update related to the battery management system. This did not solve the issue, it continues to stop while in traffic and the dealership refuses to do anything to figure out the cause.”

“Over the last 3 months at least a dozen times the 12v auxiliary battery is completely dead after parking the car outdoors for an hour or so. This poses a safety issue, especially at night because you cannot easily access the car. You have to fumble around trying to get the key hole cover off in order to use the key supplied in the fob. Once you get access, you then have to press the 12v reset button in order to get the car started. This issue has been reported on the Hyundai sonata forums since the introduction of the 2020 sonata. At this point the dealer has not been able to find the issues as they say it has been occur while they have the car. Asking for the problem to occur while they are watching is unrealistic . Their calls to Hyundai tech support has been useless as they claim to have not heard of this issue.”

“DRIVING ON DRY ROAD, IN MIDDLE LANE OF THREE LANES GOING 65 MPH. SUDDENLY, RIGHT REAR TIRE "POOFED" BUT I KEPT CONTROL, STARTED TO LOOK RIGHT TO GET OFF ROAD. TOOK FOOT OFF GAS, DID NOT PUT ON BRAKE. SUDDENLY, LEFT REAR "POOFED" AND THEN AN EXTREMELY LOUD-METAL ON METAL- SOUND OCCURRED BACK LEFT AND MY CAR JACK KNIFED INTO THE PASSING , FAST LANE. A DUMP TRUCK TRAVELING IN THAT LANE STRUCK ME, FRONT END AND MY DOOR. THE TRUCK HIT ME AND I ROLLED INTO THE GRASSY MEDIUM, ROLLING OVER SEVERAL TIMES. THE SAFETY DEVICES WORKED FABULOUSLY AND MY ONLY INJURIES WERE FROM THE SEAT BELTS WHICH SAVED MY LIFE. I AM LUCKY TO BE ALIVE AND I HOPE THIS DOESN'T HAPPEN TO SOMEONE ELSE. I WAS IN ICU FOR 5 DAYS AND HOSPITAL FOR A TOTAL OF 9 DAYS, I AM WILL BE RECOVERING AT HOME FOR MONTHS. I WOULD LIKE IT INVESTIGATED THAT EITHER A MECHANICAL ISSUE OR TIRE ISSUE CAUSED THE ACCIDENT. I ONLY HAD 2300 MILES ON THE CAR.*DT*JB”
