I have a 2012 Buick Enclave with 107,000 miles. My transmission was slipping when it changed gears. I took it to several shops and every mechanic said Enclaves have transmission issues and it would need to be rebuilt. I called my local dealership in Valparaiso, Indiana and asked about the cost. I was told that it would be around $4,350 but I might be able to obtain a discount depending on whether I routinely repair my car at their shop and whether I was a long standing customer who purchased vehicles from them. I found that a bit discriminatory so I tool my vehicle to a local transmission shop and have the transmission rebuilt for $2,850. They used 2020 GM parts to rebuild the transmission. Buick said the transmission issue for this year is not under a current recall. However, I see alot of transmission issues with 2012 year online. There also is a class action suit for later years. I feel GM should share in the cost to replace this transmission as a matter of good client care; especially since this issue on-going. I am so disappointed with this vehicle. It was the first vehicle I spent so much money to purchase. I guess I had to high expectations from GM.
