The vehicle brake lights stop working. The car will not start normally and will not shift normally. A fuss will fail over and over again. Hyundai dealer identified that the hecu is faulty.

I have a 2010 hyundai genesis 3.8 coupe 6-speed automatic with paddle and sport shift. I have had an ongoing issue with the vehicle for several months now not shifting properly. Sometimes it wont shift out of 1st gear and when it does it will unknowingly downshift and get stuck in a gear. Since the issue began, I have received several speeding tickets and had near death experiences due to the shifting. Sometimes it will increase and decrease speeds and the rpms will raise sometimes up to 6000 before it will shift or I have to place the car in park and turn off the ignition for the shifting to begin working properly again. I have to ask myself everyday if I am willing to risk my life for the issue because I have had so many near death experiences with this. It definitely needs to be looked into!!!

It does not shift properly causing it to decrease or increase speed without pressing the gas pedal. The problem also causes the vehicle to exceed recommended RPM level which causes the vehicle to get stuck in one gear and makes it difficult to stop the vehicle. This issue has caused instances where I have had to swerve off the road to avoid collision.

Stability control warning light would come on, car wouldn't shift out of 2nd. Made 3 or 4 trips to the dealer for that to get fixed. Next, with foot on brake, car in park and fob in car, the car would not start. When you hit the start button, it would just go to accessory mode. Two trips to dealer for that one. Waiting on a tow now for 2nd time in two months with the latest issue - while driving, car just dies and won't restart. The first time, was told it was a 'loose connection to fuel pump.' very scary! Thank god I wasn't on the freeway either time this happened!

The manual transmission in the 2010 hyundai genesis coupe is very problematic. Very often the gear selection is rejected not allowing the operator to up shift or downshift. Second gear and fifth gear are the worse. Grinding often occurs when shifting into 2nd gear or 5th gear. I was merging into traffic on interstate 495 in massachusetts when my car would not shift into 5th gear. The transmission simply started to grind. When merging into traffic at 50-60mph an operator needs to shift from 4th to 5th and I could not. I had to quickly downshift into 4th gear to try and keep accelerating. Any shifting into 5th gear after approximately 3,400 rpms resistance and often grinding will occur. This can very easily cause an accident, expecting to be able to shift into the next higher gear and not being able to do so. I have taken my car to a hyundai dealer and "they could not replicate the problem". I took the service tech for a ride and the car ground into 5th, and I was then told "this is normal operation of the transmission". Hyundai does not want to remedy this problem, and eventually many genesis coupe owners with manual transmissions will be using lemon law protection to have their cars fixed.
