The failure mileage was 35,652.

Electrical System, vehicle Speed Control, engine

I was driving down the road and came to a stop at a stop light. After accelerating again my car lost the ability to increase speed above 20 miles/hour and would not shift gears. I was heading to the turn lane to get on the interstate and quickly had to change lanes to find an area to pull over as I could not reach highway speeds. I turned the car off. I turned the car back on and the problem resolved. This is the second time this has happened. I have seen this problem mentioned dozens of time on Reddit message boards including Hyundai buybacks on some of these vehicles. It doesn't sound like Hyundai has any idea what is causing this issue. This issue should be looked into further.

I didn't notice any problem shifting into 3rd and above. I drove to a gas station for fuel and shut off my car. When I started it and began to drive, I received an immediate warning to take the car to a dealer and the check engine light came on. The car had the same problem getting out of 1st gear at each of the traffic signals I got caught at on my way to the dealership about 2 miles away. The following day, the service department contacted me and determined I needed a new transmission due to the failure of the Dual Clutch electric high pressure oil pump in the transmission. They submitted a parts request and Hyundai approved a refurbished DCT warranty replacement. The transmission only has 50200 miles on it I am second owner but the car was a CPO so I have full warranty coverage. I was given a loa...

Electrical System, service Brakes, forward Collision Avoidance

My vehicle activates the emergency braking system while driving. It has happened several times now, almost causing a collision. I took it to the dealership, they held it for a week and gave it back to me telling me they could not find anything wrong with it. They did not fix anything at all. It has since done it once more.
