I took my GMC terrain 2022 car in for oil change and transmission fluid change. Dealer told me there was a slight leak in transmission and would put dye in when they changed fluid. Car transmission is under factory warranty. After they completed service they said bring back in 2 weeks to check for leaks in transmission. I had to bring car back 6 days later. Transmission fluid was soaking the bottom of the car, tire, rim, and was a mess. They serviced car again and admitted to overfilling transmission on the first service. They drained transmission and refilled with new dye. They said they wiped up the fluids and I left dealership. I took to car to car wash to try to clean everything up so I could watch for leaks. Within 30 miles of driving car was completely covered in transmission fluid again. Inside tire was soaked under car was dripping fluid, and transmission fluid pooling on inside of front drivers side rim. I called and demanded a refund Due to issue reoccurring. They said they would issue refund, However they refused to correct issue that only occured after they performed maintenance even though car was under warranty. I took car to new dealer and they could not believe the mess on the car and the fact that the dealer just threw their hands up and said they were done. If damage was done by performance GM I want them to pay for damage as it would not be covered under warrenty.
