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.

Transmission slips. I'm at 80K miles. I thought I could determine which gears it's slipping but at times it's been between 2 &3, 3&4. the car will rev high on rpms with out correlating speed and then catch. Jerks between gears at times. I feel so unsafe in this Hyundai and I don't I can afford the cost. I know it's not from my driving.

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.

Hello, my 2012 Genesis sedan 5.0L R-spec only has 33K miles on it and I bought it at 21K. I am the 2nd owner and therefore technically outside of warranty, I know this. However, my Genesis' transmission has been experiencing rough and occasional slipping shifts every time I drive it. Through research amongst other owners of the same make and model, I have discovered that this issue is quite common in this model year car and that Hyundai has already replaced hundreds if not thousands of these faulty transmissions. When this occurs, it indicates a flaw in the manufacturer's design and I believe Hyundai should take responsibility for that fact and repair or replace the parts under warranty or goodwill if outside of warranty. This problem could cause major damage to the car or myself when driving if it decides to suddenly slip when I am making a turn with oncoming traffic on the way. This makes me feel very unsafe when driving my car. Specifically, the problem occurs mostly shifting between gears 2&3, 4&5 as well as 5&6 and usually slips rpms a little from 6 to 7 or 7 to 8. the shifts, when not slipping, will be rough and abrupt. I wouldn't describe it as slamming into gear, but rather a jolt that can be felt in the seat and just isn't as smooth as other gears. I also experience issues when shifting from park to drive, drive to park, park to reverse, reverse to park, or any combination of the described shifts will create a rough clunk when the gear engages. You can also feel a thud when kicking down the accelerator to pass a vehicle as it downshifts through gears. All of these symptoms on top of a fluid change producing no positive results indicate a problem with the transmission at 33K miles.

Sometime the transmission shift very hard while driving, it has a wild unexpected jerk

- Jacksonville, FL, USA

Our 2012 Genesis 4.6L V-8 with the 8 speed automatic transmission has an intermittent problem with the transmission. The transmission will at times and w/O warning shift harshly during up-shifts even at low motor speeds which can cause the car to lurch unpredictably, this behavior is very concerning particularly during turns on city streets or in slow stop and go traffic conditions. This behavior started at about 70,000 miles and now is at 79,000 mile. Initially this problem was very intermittent and would happen whether the car was hot or cold. Now this problem can occur for a few days at a time then suddenly start shifting normally for a few days then return to the harsh shifting problem. The transmission also intermittently has a down shifting issue where it doesn't seem to know when to downshift and will, as an example, delay the down shift as your slowing to stop at a red traffic light remaining in one of the higher gears then suddenly downshift into second or first gear when your nearly stopped. As you proceed following the traffic light change the transmission may shift normally or shift harshly through the next few gears or all of them. The transmission just recently has just started a new shifting problem in that it intermittently acts like it is slipping and then suddenly engages, just as if it were in neutral momentarily and then dropped into gear. The Genesis has been to three Hyundai dealers for the harsh shifting and delayed downshift issues without resolution. I would characterize the unpredictable " lurching behavior" ( a result of the harsh up-shifts) as a safety issue and to a lesser degree the delayed rough down-shifts unless of course the "bad" downshift occurs on a wet or icy pavement with the Genesis being a rear-wheel drive vehicle of course
