The failure pattern owners describe
The 2010 Tucson powertrain complaints center on transmission behavior that leaves drivers stranded or endangered. Most common: transmission fails to engage when shifting at 35–50 mph, causing the car to coast silently with no acceleration response—sometimes for several seconds—before suddenly lurching forward. One owner had the transmission replaced at 5,000 miles for the same issue; the problem recurred years later.
A second major pattern involves violent downshifting on highway ramps or during normal deceleration, with such force that seatbelt tensioners lock. Owners describe it like being rear-ended.
Shifter-specific failures include stuck shifters that cannot move into or out of park, drive, or reverse, sometimes trapping the car in neutral on slopes. One owner's plastic shifter cover crumpled after a soda spill, physically jamming the lever; the dealer denied warranty coverage. A separate recall for backlight switch failure was issued in 2012, but some VINs weren't included.
Additional reports cite sudden unintended acceleration followed by power loss, spontaneous shifts into neutral while driving turns, RPM spikes with uncontrolled gear changes, and loss of acceleration at cruise speed. Dealers consistently report inability to replicate faults and offer transmission reset or solenoid replacement as temporary fixes. One owner narrowly avoided a train collision when the shifter wouldn't move; another experienced sudden acceleration into a tree at 14,000 miles.

The transmission slips. The radio/GPS lost its audio, the manufacture will not aid me in getting it repaired. *tr
I have had my Hyundai tucson for about 5 months, about two months after owning the car the car made a loud clunk and lurched forward,like I got hit from behind or like I hit an animal. I pulled over to see if I did but nothing was there. This happened about three times before I took it to the dealer. They checked it and said everything checked out fine. They reset the transmission, they told me…
When driving and occasionally hit a bump the icon (slippery) appears on the dash and later when you stop to back up to park the gears get stuck and you can't move it to the gear to backup. Since this car has stick shift and automatic driving features you have to keep shifting the years back and forth until it jumps back into reverse. This happens to frequently.
