2024 GMC AT4 Lemon Truck
Unsatisfied Customer, 06/17/2024
2024 GMC Sierra 1500 AT4 4dr Crew Cab 4WD 6.6 ft. SB (3.0L 6cyl Turbodiesel 10A)
After being a FORD guy for over 35 years, I decided to give GMC a try :/ I drive out with the brand new AT4 on thursday evening, after just 40 miles I wake up in the morning to find a big puddle of trans oil on my driveway. I call the salesman and drive it to the dealership, on the way there almost complete shutdown, engine over heat is on, A/C out!! Engine noise!!, get to the dealership … wanting to talk to the manger, to no avail! Salesman and service tech tell me theres nothing to do but put it in to service. Absolutely displeased and irritated with GM dealership,..DO NOT BUY GMC! does Lemon Law apply here?
