Had a 2021 GMC Sierra 1500 at4 5.3L
In December 2024 I had my 2nd issue with my truck having just 60k kms...that issue I was told was due to a faulty TCM. Truck sat at local dealer for 40 days while they had my in a compact Toyota cuv with all season tires on it
Dealer gave me heads up that GM been having major faults with their tcm that come from mexico made parts and the quality was not up to par. And they added they didn't know how long I would have to wait for a tcm to repair...could be a month could be 6 months.
Wasn't pleased, asked the dealer and GM both to buy back truck and let me walk away from GM. I wanted to shift over to Toyota and try a Tacoma which was only truck in my price range. They wouldn't and said only thing we'll do is put you in another gm.
They wanted 24k more for a 2024 Sierra At4 then I paid in 2021....which was absurd and they would give any deal....not only that they simply paid off my truck what was owing which now with a so called 24k increase in the trucks price there was no way that is all they could give me any truck.
Ended up going into a 2024 GMC Canyon at4 which so far is okay but I don't have a good vibe from reading all the bad reviews.
Gm needs to get away from the bad quality parts, and service is sub par from GM to all its customers.
My first issue I had with the truck was rotors...at 11 months old I was getting a vibration. They blamed it on lack of use and I hadn't kept maintenance up on the rotors and my expense to replace.
To tell you the truth I think they should have degraded the price of all their trucks by 24k not increase. The quality is not there and consumers are getting robbed by GM. There is nothing to protect consumers on this and GM gets away with so much.
I hope my truck lasts till I pay it off at the end of 5 yrs then I will sell and buy a Tacoma with a 6 speed manual.
