Potential buyer beware! I purchased a new GMC Sierra 15OO in 2024 and was thrilled with the vehicle initially. Unfortunately, the excitement turned to disbelief quickly. In just over a year of ownership the truck needed two major repairs with only 26,000 miles on the truck. One repair being a failed fuel pump and the other being the valve body for the transmission. Although the repairs were done under warranty, this situation is unacceptable with a new vehicle. To make matters worse, GM is aware of the valve body issue in the 10 speed transmission (check the internet for the failures across the country) and has done noting to repair, reengineer or modify the failing part. GM is simply replacing it with the exact same part with no guarantee it will not fail in another 20,000 miles. Adding to the upset, the dealership had my truck for a month waiting on the backordered part and there were 7 other Sierra’s in front of mine waiting on the valve body. Sadly, I traded my truck in once repaired for another make simply to avoid any future headaches with the Sierra. So if you are shopping for a truck, reconsider before buying a new Sierra and do some deep research on the issues.
