1.ENGINE WILL NOT SHUT OFF WHEN VEHICLE IN PARK. HAD TO DISCONNECT BATTERY. there was no warning. 2. LKAS warning light remains on. 3. Caution light remains on on the dash. 4. Anti-braking system highlights when immediate car in front of me makes a turn without me being close to it. The first thing the dealer asks is do I have extended warranty! They stated they couldn't get to the repair until maybe Thursday. I'm really afraid to drive my car.

The check engine light come on for no reason. The car locked me out while running and both key fabs wouldn't unlock it from the outside. The smart trunk doesn't work. When you lock the doors, the driver's side won't lock.

Vehicle would not shift up to the next gear and and started attempting to shift but failing every time as it passed 2000 rpms. Incident happened while passing another vehicle, after an extended time of vehicle not being able to accelerate while attempting to pass the brakes had to be applied in order to avoid a collision with an incoming vehicle. The vehicle later failed completely and all power from the engine was lost and started rapidly decelerating then finally came to a complete stop. Instrument and electric power was still on but there was no power from the engine. Vehicle would not move for about 15 minutes, then it finally had limited power to 45mph

I was driving northbound on I-295 in Washington, DC when my check engine light illuminated and the car began to slow down in extremely heavy traffic and I lost the ability to accelerate. I attempted to accelerate in order to get my vehicle off the busy highway and to a safer location, but I was not able to go more than a few meters. It was fortunate that I was not seriously hurt or killed. This is clearly a serious safety issue and I am surprised that there has not been a recall to fix this problem, especially considering that it appears to be something that has been happening to many Hyundai vehicles for some time now. After more than one (1) hour, I was rescued by a towing company that left my car at the dealership. The dealership has discovered that I require at least a throttle body assembly to repair the issue and has ordered the parts which means that I am renting a car until the repairs are made (the part will take several days to be delivered). After the throttle body assembly is installed, the dealership will rescan to see if that eliminates some of the other codes that were discovered.

This is an ongoing safety issue that I've tried to get the dealership to address. From a stop or slow idle, the engine exhibits acceleration hesitation. This hesitation lasts up to 2 seconds and when trying to merge into traffic has nearly resulted in accidents numerous times. I believe a Hyundai whistle-blower came forward recently to expose this ongoing issue but Hyundai has yet to address it.

The vehicle briefly shut down on its own for no apparent reason while in motion at rate of 25mph at nighttime, the vehicle turned back on a second later as if nothing happened. The cause of the shut down is unknown and could have caused an accident had I not been on an empty road. While the vehicle was off, I had no control over power steering or accelerating, the entire vehicle became unresponsive with the both the entire instrument panel and exterior lights off.

I bought Genesis at March 24, 2015, and I am not owner right now because I sold that car. When I bought car, there were noise at engine at new car. After checking the car, Hyundai engineer said " short block problem". it is exactly same problem of sonata (theta 2 engine). I think Genesis engine(rhamda 3.8) also have problem. I will attach related paper. Thank you.

The car engine will spontaneously stop while the car is in motion. This causes me to lose all power steering, brakes stability control etc. This has happened on city street while the car was in motion. The car was moving forward in a relatively straight line. It has been "fixed" but not fixed. It is at the dealer for the 2nd "fix". the 1st "fix"was 10/12/15. The 2nd "fix" began 10/27/15 & is still underway. The consumer stated a diagnostic report found 32 codes. The consumer was provided a loaner vehicle. Updated 10/25/2017

problem #2

Genesis

  • 10,786 miles
After accelerating from a stop light behind another vehicle, there was a loud cracking noise heard from behind the dash board and the car suddenly and violently accelerated without warning with a loud "boom" in the back as though someone had hit me from behind, but no one had hit me. I had to brake hard to avoid hitting the car in from of me. When the car violently accelerated the back of the car dipped down (and the front up). I immediately called the dealer and reported this and the car is now in the repair shop. There are no error codes in the gds system for this incident and they are unable to reproduce. This was a very frightening experience and my trust level is now 0/100.
