BOYLSTON, MA | 2023 GMC Sierra 1500August 4, 2025
I purchased my 2023 gmc sierra here and have had nothing but ongoing issues that seem to never be fixed. The latest issue was with the exhaust which was installed at the dealership. Inside the muffler the mechanic found broken welds which are causing a loud rumble in the vehicle. The service department claims the trucks exhaust is no longer under warranty, and if I wanted to try calling the exhaust manufacturer myself then I could try that. This truck has 19k miles on it and was purchased not even 2 years ago, and the exhaust was installed at this dealership, yet somehow I have to pay full price out of pocket for the fix? Not only that but i was told to call the parts manufacturers myself? So after taking a half day at work to come to the dealer, I am told the problem is now not covered by all the warranties I purchased with the vehicle, and on top of having to pay to try and solve the problem on my less than 2 year old truck, I am responsible for reaching out to the parts suppliers to see if I can get any better answers. Experience here was not great when it was the previous owners, and we are starting off on terrible terms under new ownership. Will be headed to another dealership and putting this review up on Google soon.
