2012 Hyundai Veloster Speed Control & Cruise Problems

After an update for a recall for brake issues, the dealership updated the knock sensor update without my consent. After the knock sensor software was installed, my 2012 Hyundai veloster will not operate without going into protection mode. Hyundai states that they can not reverse the software update to make my vehicle operable again. This has already come up as a safety concern as my wife was on the interstate when the vehicle shut down in 70+ mph traffic.

On 08/17/2022, we had to have the car towed to the dealer for a very concerning issue. My son was driving down a major highway (middle lane) and as he attempted to accelerate, the car was not responding. It was like the car went into neutral and the rpms went up, but there was absolutely no acceleration. It was scary as he had traffic all around him and needed to get over to the breakdown lane. He finally got over and the car would not move forward or reverse. The check engine light also came on, so we had the car towed once again to the dealer. Once there, they looked it over and said it needed a new MAP SENSOR. They also stated that they thought the problem was with the DCT CONTROL MODULE. They said that they needed to do a RETEST of the DCT CONTROL MODULE and followed through with that. When I went to pick up the vehicle, I was told that the car was working properly, but they couldn’t be sure that it wouldn’t happen again. If the same thing happened again then they would need to replace the DCT CONTROL MODULE. After paying $800 to have my car fixed, I didn’t feel very hopeful. It makes you pretty anxious to drive a car that just loses power out of nowhere. Under normal conditions, losing acceleration on a major highway could severely affect the driver’s ability to control the vehicle and maintain a safe speed in traffic. This could cause a major accident. Here we go again. On 09/23/2022, my son was driving down the highway when he suddenly lost power again. The same scenario played out once again, only this time he didn’t have much room to pull over. He was forced to pull over in an accident-prone area of 77 South with a cement barrier next to him. Soon, he saw police lights behind him. The police officer was very concerned with getting the car towed quickly and showed my son the skid marks on the pavement from a previous accident. Now the dealer is saying its the transmission and transmission control module. This car is very unsafe to drive.

ROLLED BACKWARDS WHILE PARKED IN MY DRIVEWAY TWICE AND VEHICLE WAS FOUND OUT IN THE ROAD BY MY NEIGHBORS. I WAS DRIVING IT A WEEK AGO AND MY RPM'S WERE TACKING REALLY HIGH BUT COULD NOT ACCELERATE SPEED AND I WAS IN 6TH GEAR AND IT WAS TELLING ME TO SHIFT TO 6TH THEN 5TH BACK AND FORTH. HAD IT CHECKED OUT AT DEALERSHIP AND THEY SAID MY CLUTCH HAD ABNORMAL WEAR AND TEAR BUT WASN'T COVERED UNDER WARRANTY. THEY DID NOT CHECK THE PARKING BREAK TO SEE IF IT WAS WHAT CAUSED THE MALFUNCTION OF THE CLUTCH. THE CLUTCH NEVER GAVE ME ANY PROBLEMS IT WAS JUST THE CAR LAGGED WHEN TRYING TO ACCELERATE SPEED.

ABOUT 10 FEET FROM MY PARKING SPACE, I PREPARED AND ALIGNED MY EYES TO PULL FORWARD INTO THE SPACE. SUDDENLY, MY CAR ACCELERATED AND I JUMPED THE CURB, AND CRASHED INTO MY APARTMENT BUILDING, WITHOUT ME BEING ABLE TO REGAIN CONTROL OF THE CAR. NOW I'VE BEEN PARKING FOR MANY YEARS, AND I WAS NOT IMPAIRED IN ANY WAY, SHAPE OR FORM. HOW FAST MUST THAT CAR HAVE ACCELERATED TO WHAT MPH? I'M TERRIFIED TO DRIVE THE VEHICLE. I HAVE NOTICED THE WHOLE TIME I HAD THE CAR ABOUT A "LURCHING FORWARD", BE IT A RED LIGHT OR IN LINE AT FAST FOOD LINE DRIVE UP. ONCE IT STARTS LURCHING FORWARD I'M WORRIED IM GOING CRASH INTO THE CAR IN FRONT OF ME IN LINE OR AT THE RED LIGHT.. ALSO, SOMETIMES WHEN THE LIGHT TURNS GREEN, I HIT THE GAS AND THE CAR DOESN'T GO ANYWHERE. THEN VIOLENTLY THROWS THE CAR FORWARD ACCELERATES. *JS

BOUGHT THE CAR BRAND NEW IN JAN OF 2012, STARTED HAVING "ISSUES" WITH THE DUEL CLUTCH WITHIN A FEW MONTHS OF DRIVING. AFTER GETTING USE TO THE NEW CAR AND HOW IT DROVE, PUTTING A FEW THOUSAND MILES ON THE CAR, SOMETHING WAS STILL NOT RIGHT WITH HOW IT DROVE. NOT GETTING THE SPEED IT NEEDED AND TACKING OUT THE RPMS TO CHANGE INTO THE RIGHT GEAR AND AT TIMES, WAS THE WRONG GEAR. WE HAD TAKEN IT TO THE DEALERSHIP IN WHICH WE GOT THE CAR, TOLD THEM OF THE ISSUE AND THEY SAID THERE WAS NOTHING WRONG AND THAT IT WAS "NORMAL" WITH THE DUEL CLUTCH AND THAT WE HAD TO DRIVE IT MORE IN MANUAL MODE, WHICH MADE NO SENSE TO ME. AFTER A FEW MONTHS, THE CAR GOT PROGRESSIVELY WORSE....COULD NOT EVEN MERGE OUT INTO TRAFFIC THAT WAS GOING 30-35 MPH. HAD TO ALWAYS DRIVE THE CAR IN MANUAL MODE AS OPPOSED TO AUTOMATIC, ADHERING TO THE DEALERSHIP. WELL, ONE THING LEAD TO ANOTHER AND NOW THE CAR IS BARELY DRIVING AND BECOMING A MASSIVE SAFETY ISSUE, AS WE HAVE TO USE THIS CAR TO GO TO AND FROM WORK AND THAT ONLY. WE HAD BROUGHT IT TO THE ATTENTION OF THE DEALERSHIP, ONCE AGAIN IN DEC AND NOW... THEY ARE HAVING "ISSUES" WITH THE DUEL CLUTCH AND THAT THIS CAR WAS...A "GUINEA PIG" AND BEING MADE A COMPLETE MOCKERY OF THIS PARTICULAR DEALERSHIP. WE HAVE ESCALATED THE ISSUE TO CORPORATE OFFICE AND I WILL NEVER PURCHASE ANOTHER VEHICLE FROM THIS MAKER EVER AGAIN... NOTHING BUT A HORRID EXPERIENCE. *TR
