Transmission nightmare
Scott W, 03/25/2023
2023 GMC Sierra 1500 Denali 4dr Crew Cab 5.8 ft. SB (5.3L 8cyl 10A)
We purchased a 2023 GMC Sierra Denali recently and have been experiencing a shudder and shaking when driving since day one. We took it to the dealer to have it checked out. The service manager acknowledged the shudder and told us that it was in an acceptable range and that GMC has bad transmissions. When talking with the sales staff and sales manager, they also indicated that many people … have had the same complaints. The sales manager took my information and told me he would check into things and get back to me. That was almost a month ago and still no call. I have since talked to my sales person and she also told me that she would get back to me. That has been several weeks now. I didn’t expect when paying $75,000 for a new truck that we would feel like we are driving down a cobblestone road. Very disappointed. No calls, no response. Don’t NOT buy a GMC!
