NHTSA Complaint #11635141 — 2015 GMC YUKON XL

Transmission failed and was replaced by GM dealership under warranty at 20,670 miles after rough shifts and jerking and lurching movements when driving and when putting vehicle in gear. Truck would also roll if on a hill in Park. Now at 53,438 miles, the same dangerous problems are occurring with only 33,000 miles on the replaced transmission and after inspection, the dealership says the transmission needs to be replaced again. Appears GMC transmission is faulty and dangerous to drive and needs replacement very early in cars lifespan and a transmission should not need replacement so early especially when maintained correctly. Transmissions should last more than 20,000 or 30,000 miles before failing. Estimate for new transmission is $10,000. Called GMC customer service and said nothing they can do out of warranty. Dealership inspected and confirmed problems both times. Check engine light appeared the 2nd time indicating transmission failure but not the first time.
