“The Hyundai Genesis has a transmission problem where it slips out of gear and rough shifts 2-3rd gear and 4-5th gear. I took the car to the dealer and they could not duplicate. They updated software, no change. I contacted Hyundai multiple times. I am second owner of vehicle with 45k on it. They would not honor factory warranty since I am second owner. The TSB no. 15-at-005 applies to this problem. The transmission should have been recalled instead of TSB.”
NHTSA complaint #11395908, filed 2021-02, 45,000 miles“While accelerating, the transmission would slip. This would cause the car to lose power while the gear slipped, then the gear would catch and the car would surge forward. The dealer could not find an issue and gave the car back to me. The problem returned, so I had the car towed back to the dealer. The dealer replaced the automatic transmission and the issue resolved. The replaced transmission began to exhibit the same behavior approximately 35,000 miles later.”
NHTSA complaint #11229849, filed 2019-07, 55,000 miles“When driving at slower speeds (<30) on a city street, while driving straight, as I lifted my foot off the gas pedal, the car continued to accelerate. Pressing the brake slowed it but did not stop the problem. I pulled the car over and put it in park. When placed in park, the engine revved loudly. I pressed the button to turn the ignition off. This has happened 3 separate times. Once in july and 2 times on august 21.”
NHTSA complaint #10901958, filed 2016-08, 60,000 miles“I was trying to turn left onto a cross street and as soon as I got moving the car lost power for a few seconds that started going again...this as happen 4 or 5 times and I only owned this car for 3 weeks. Hyundai can't duplicate this happening....its on the Hyundai forums and they sent me here.”
NHTSA complaint #10637820, filed 2014-09, 49,000 miles“While driving home today my car killed dead which caused the power steering to go out while I was turning off fm1960 onto kenswick in humble tx which is a very busy street. This is the 3rd time that this has happened I wrote a letter back on 5-22-15 to Hyundai warranty department and have not been notified by them. This is very dangerous I could have been rear ended and god knows what else. Please have this matter checked into with Hyundai. Thank you very much.”
