Brakes seize up while driving and then cannot move the vehicle. This causes a dangerous situation while driving and then breaks lock up and cannot move car even though vehicle is on and then stopped for a stop light. Car must then be turned off and sit for about 30 minutes so it can unseize and when that happens, you can then resume driving and then check engine light comes on. Brake lights were staying on even when vehicle is shut completely off. ABS and ESC lights stay on consistently and never turn off. Vehicle brake switch was replaced at Carolina Hyundai of high point, NC. So break lights have been repaired. They had to order the stop switch lamp replacement for recall as it was never done and will be fixed in next week. 3 door handles fell off and cannot open the rear driver side door at all. Window electric system won’t let windows go up and down and had to make a latch pull string to open driver door. Passenger door will not open at all and no handle and is a dangerous situation. Break switch not being replaced would have cause an electrical fire and is a complete dangerous vehicle even after being inspected less than a week ago

We purchased this vehicle used 9/2022. A week later it began to jump upon accelerating and slowing down. We took it in and they said it was the power train control module and our warranty would not cover it. So it would cost us around $1600. We can’t afford that. We have only driven it a few times since. We were parked in front of a curb and the car accelerated us into a curb. Now, the ESC OFF, ABS, and engine light are illuminated. This is not a. It also wear and tear issues, as I’ve seen many others posting similar experiences. Our car is an ‘09 with almost 90,000 miles on it.

Was driving and out of no where the engine light came on and all power was lost. Could hardly control the steering. Pulled over and waited a moment and started the car again. After two minutes the same problem happened. Mechanic said to bring it straight to hyundai and demand a new engine. This should be a recall. Very dangerous to happen while driving.

Check engine light is on. Hecu internal failure. Active dtc present: c1237 primary pressure sensor signal. Sensor failure inside the ABS control cycle. Values at pressure sensor changed from 0.3 bar to 78.0 bar; no change in supply voltage. Supply voltage constantly at 14v. Hyundai has mentioned that there are no active recalls and that this part is life threatening if it fails - but since the warranty has expired they are shying away. Online there are several known issues with hyndai and hecu. Specially for models before 2009. Its hard to believe that hyundai is not aware of this problem and seems like they are avoiding their responsibility and playing with human life. Would appreciate if the government can do something.

The car drives normally until you press on the brakes after going high speeds it jerks. At stops if the car isn't in neutral the engine stutters we've replaced the cam shaft sensor 3 times now and that's the code that comes up everytime the check engine light comes on after the jerking. We also replaced the spark plugs and coils hoping it would help the shaking at stops and it didn't.

I bought my car on july 18th 2016. That is the only time I have had a passing inspection sticker. The check engine light came on shortly after I drove off the lot. Over the past two years I have tried to get it fixed. The code is a p0442 code. I have brought it to 4 mechanics and they can not find the issue. We have changed the gas cap twice, done purge valves, and hoses. We also did 7 smoke tests and still can not find the issue. I still owe 7,000 on the vehicle and have been paying it but it's not drivable due to the rejection for the inspection. I know of 2 hyundai sonatas with the same problem. One being a 2006 and the other also a 2009. I keep looking to see if there is a recall but haven't found anything. I don't have any other options as far as what to do. Please help me if you can it would be greatly appreciated. Thank you for your time.
