Consumer Description

* The 7 speed DCT transmission (automatic) jerks and down shifts hard and lunges forward when braking and coming to a stop. Upon acceleration the transmission also is jerky in first gear. It's like driving a manual transmission for the first time. * If not properly controlled by braking, I could hit the car in front of me. * I have had the vehicle in twice to the Hyundai dealership, but they say the judder not bad enough to replace the transmission. They also did a software update that did not change anything. There is a Hyundai Technical Service Bulletin #22-AT-007H * There were no warning lights or messages to indicate the problem. The vehicle currently has 35,200 miles. I noticed the bad shifting at about 12,000 miles and it has gotten worse.
