What 269 owners told NHTSA about the 2012 Hyundai Genesis Coupe

I am reporting an electrical problem w my 2012 hyundai Genesis. My back driver's side door lock just stopped working in 2021 & a few months later , my front passenger seat door locks also stopped working. I brought it in to the dealer this morning to have both locks checked. I know the back seat door lock is the actuator & im assuming that’s the issue w the front one too. I’m waiting to hear back from the dealer what the problem is, but actuators on the 2012 genesis are defective or it’s an electrical problem. No accidents happened bc of it, I was just told to report this issue.

When the screen becomes scrambled, it creates a major safety issue. If there was an person or object directly behind the car when backing up, you would not be able to see it. There are no warnings or notifications from the car when this happens.

While turning at low speeds, the vehicle will turn off completely. This kills all power steering and brakes. This has occurred on several occasions and is documented on the web and genesis forums by other Hyundai owners as well, so this is not an isolated case. There was no warning of any kind that the car would be shutting down. The problem has not been reproduced by the dealer and that is the problem....you never know when it's going to happen and is extremely dangerous.

I bought the car new, it has 39k miles on it. 5k miles ago while repairing the water pump under the 10 year powertrain warranty, I reported to the dealership the engine was making bad knocking/grinding sounds at startup and the oil consumption was high. The dealership dismissed this as "normal" for this car. 2 weeks ago the engine seized up without warning, no loss of power or harshness, no engine check light or low pressure warning. I had just left the I15 in rush hour traffic traveling at 70mph. The starter could barely turn the engine, I thought it was a flat battery. After some time I managed to restart the engine that now sounded like a machine gun and limp a few miles home. I tried replacing the oil, which I do on a regular basis, and it contained metal fragments. The warranty expired in Dec 21 but I still contacted the dealership. They have inspected the car and report engine damage requiring $3,200 of parts. Both the dealership and myself have contacted Hyundai Corp. and opened a Consumer Affairs Case on 5/25. Yesterday, 5/24, the case manager spoke to me to get details and obtain evidence I might have including original proof of ownership (documents he should already have). He told me he would have a decision in 2 to 4 weeks. I asked about leaving the car at the dealership, and he replied that it was the dealerships decision, but I would probably need to remove it. I would consider the car dangerous to drive, but the case manager does not seem to consider this and my impression is that Hyundai will refuse any responsibility for this problem. After googling this, I see you have sued Hyundai for what appears to be exactly the same manufacturing problems in other engines from the same time and wonder if these should also apply to the 5.0 liter engines. Has Hyundai acknowledged a problem with these engines and corrected it? If so, why has a recall not been issued, and I not charged for their manufacturing mistake? The dealership has rebuilt the engine and returned my car, charging me $3400.

Brake system failure. Brake pedal and goes all the way to the floor. Hyundai dealership explained that the HECU has failed. In 2014 there was a recall on this car for this issue, Hyundai Recall 114. This recall was for "GENESIS SEDAN HECU INSPECTION AND BRAKE FLUID REPLACEMENT". The known issue is that the part breaks down over time and just changing the brake fluid doesn’t stop the corrosion process. The HECU part should have been replaced and not allowed to degrade further as it has now done on my vehicle.

MY VECHILE STALLS WHILE DRIVING AT VARIOUS TIMES. THIS COULD CAUSE A SERIOUS ACCIDENT IN WHICH LIVES COULD BE LOST . THIS EEMS TO BE PROBLEM WITH THE GENESIS FROM 2012 TO 2016 FROM MY RESEARCH. I AM NOT THE ONLY OWNER WITH THIS PROBLEM . THE DEALERS CANT FIND THE PROBLEM OR WHY IT IS OCCURING . THE DEALERS GIVE YOU NUMEROUS REASONS AS TO WHAT MIGHT BE THE CAUSE OF THIS PROBLEM, BUT THEY ARE NOT SURE . THIS COULD COST A CONSUMER $1000 OF DOLLARS JUST TO FIND OUT WHAT THE PROBLEM IS . THIS OCCURS WHEN JUST DRIVING DOWN A STREET, ON CURVES OR GOING STRAIGHT. I HAVE NOT HAD AN ACCIDENT YET! IM TRYING TO AVOID THIS .THIS OCCURS WHEN MY GAS TANK GETS LOW , THAT IS WHAT I HAVE NOTICED .
