Genesis Coupe

6-speed manual transmission hard to get into some gears. Grinding noise is heard on upshift from 2nd to 3rd and downshift from 6th to 5th. This is the second transmission the dealer installed. The original one had similar issues when the car was less than a year old and it was replaced by the dealer under warranty.

Transmission grinding/syncro issues, 2nd, 3rd, 5th gear grind, gear lockout, gear rejection(intermittent daily occurrence with no pattern), can causing loos of control of the vehicle, inability to safely accelerate etc. Tech drove the car for 10miles and couldn't replicate, would not perform any more tests. Common issue on cars made after 2009 up until 2013, manufacturing defect.

When starting the vehicle with foot on the clutch, it lurched forward hitting a parking barrier. Dealer denied mechanical causes. From the time I bought the car, it has accelerated on it's own, going to the max in rpms, at random times. I can take my foot off the gas and it will drive itself. When I try to come to a stop, it will accelerate and I have to counter by hitting the brake. When taken to the dealer, they couldn't "replicate" it. When I argued with the man, he said he would honor the warranty when they could replicate it, though the warranty is now expired. I asked for something in writing, he initialed the work order. Also, the front, under the bumper, is way too low and made of weak material, so when I have to go over any kind of dip, it drags, which has caused the piece to break. This also got up into the fender-well, which caused a hazard with my tires. I am stressed and scared of having a dangerous accident. I am considering trading the car in, but worry for the next owner. I no longer trust Hyundai. I feel like my safety is not a priority for the company. They do not search for the cause, just send me back out in a defective vehicle.

The contact owns a 2010 Hyundai Genesis coupe. The contact stated that while driving at various speeds, the vehicle erroneously downshifted and dramatically reduced vehicle speed. The vehicle was taken to a private mechanic where it was found that the transmission control module had failed. The vehicle was not repaired. The manufacturer was contacted about the failure and informed the contact that the vehicle was not included in the manufacturer's recall. The failure mileage was 56,000. The VIN was not available.

The 2010 Hyundai Genesis coupe has been defective for a few months now. It will abruptly shift from 3rd to 1st and from 5th to 3rd by itself. It will also not accelerate when you need it to. I was recently almost involved in accident because of the shifting issues. I have contacted Hyundai several times and they refuse to assist me. What are they waiting for, me to die in accident or something?? I want something done very soon or I will get legal counsel and they can speak with them.

Genesis Coupe 6-cyl

  • 63,000 miles
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!!!

While driving my 2010 Hyundai Genesis coupe 3.8L track model, I experience severe problems with the transmission. When shifting from 1st gear to 2nd gear whenever the temperature is below 30 degrees Fahrenheit the transmission grinds going into gear. Hyundai usa had a tsb about it, and the transmission fluid was changed under warranty. A week later the problem is still occurring. Hyundai has not been helpful in fixing the problem whatsoever since. When it is very cold, the transmission will not allow me to shift into second gear at all, it'll grind and make noise and block me from shifting. When this happened, I had to quickly depress the clutch and let the car roll back down to a stop. There was a lot of traffic this day and I was almost involved in a collision because of this problem. When approaching highway speeds and shifting into 5th gear, the transmission grinds again. This is usually around 50mph and at around 2600-3000rpms. I have to force the shifter into the 5th gear slot. Should the transmission block me from shifting into 5th, as it does sometimes from 1st-2nd gear, this will certainly result in an accident. Again, Hyundai motor usa is not being helpful at resolving this issue. Since the transmission fluid change, Hyundai will not approve any other warranty related work.

While the car is warmed up and at operating temperature, the rpms will "hang" (hover around 2500 rpms) for 3-5 seconds before returning to idle.

Trying to shift into any gear during cold climates is very difficult and sometimes impossible on the first attempt. Multiple gears grind when going into gear specifically 5th and 6th gear, occasionally 3rd. I took it to a Hyundai dealership to get fixed and they said there was nothing wrong with it. This is a well known problem among the Genesis coupe community and Hyundai refuses to acknowledge they have a problem.

Transmission is difficult to shift at times mostly into second gear. This can cause a rapid deceleration in traffic and I have seen the vehicle behind me do a nose dive hitting the brakes because my vehicle disrupted traffic flow. Entering fast moving traffic is also a concern for this very reason. Dealer has replaced transmission several times with no change in transmission behavior.
