2016 Hyundai Tucson: transmission slipping

Filed May 26, 2026 · Transmission · CO

Transmission previously replaced after failed Judder test. Transmission is failing again: Last few days the car will accelerate to 15 then it attempts to shift and power drops and pressing the pedal has no response or very little then it changes into what feels like 4th or 5th gear at 20 mph and acceleration is very sluggish and also switching into manual gear control is completely unresponsive. Power drop at 15 mph, the transmission jumping into what feels like 4th or 5th gear at 20 mph, and sluggish acceleration — is consistent with the clutch pack slipping and the TCM essentially giving up on lower gears and defaulting to a higher gear to protect itself. Manual mode being completely unresponsive is a significant red flag — it means the TCM may have entered a limp or failsafe mode where it’s overriding driver input entirely.

The transmission began slipping and hesitating within days of purchase. The vehicle intermittently fails to accelerate when pressing the gas pedal, especially when pulling into traffic or crossing intersections. This creates a serious safety risk because the vehicle does not respond when needed, leaving me exposed to oncoming traffic. The issue is intermittent and does not always trigger warning lamps or fault codes. The problem has been reproduced multiple times by me while driving under normal conditions. The selling dealer performed only a brief test drive and stated they could not duplicate the issue, but the hesitation and failure‑to‑accelerate continue to occur. The vehicle has not yet been inspected by Hyundai, but the symptoms match known issues with the 2016 Tucson’s dual‑clutch transmission and TCM logic. There were no warning lights prior to the failure, and the symptoms first appeared within the first week of ownership. The vehicle is available for inspection upon request.

I bought my 2016 Tuscon brand new. Ever since I bought the vehicle, I've complained to the dealer about the transmission slipping. They have told me that this issue is common but there is nothing they can do. Now it seems to be getting worse so I decided to look up the problem and found out a recall notice was issued for some 2016 Tuscons but mine wasn't included. My Tuscon has the exact same problem as described in the recall issued by Hyundai. I"ve almost been in accidents because you press on the gas to go and it hesitates,l. What can I do? My Vin number is [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When coming from a stop and trying to accelerate the transmission slips and makes a strange noise. After a few seconds of releasing the gas pedal, it will drive again normally. It is intermittent and happens from either a full stop to first or first to second (while stuck in traffic). My vehicle should be included in the dual clutch transmission recall that is available for other vehicles.

While attempting to pull out of a private drive again 4 days ago, with plenty of time before on coming traffic was close, my car would not accelerate with the gas pedal all the way to the floor. It finally did accelerate when traffic was dangerously close. This has happened previously and is unacceptable. I am pregnant and this is too dangerous. Does there have to be an accident before it gets fixed? It needs fixed now! It was 6:56pm, not the prime heat of the day as many use that as an excuse. I will never buy a tucson again and will not recommend them. The morning of this incident (8a-10a) my car felt as if the transmission was 'slipping' and 'jerking' several times as I drove through the city. Again not during the heat of the day. Please contact me with any and all safety recalls. Once again I am unable to check the 'yes' box to request this information at the bottom of this form.
