NHTSA Complaint #11529747 — 2017 GMC TERRAIN

We have had many GM vehicles my husband worked at GM retired now. Our complaint is we have a GMC Denali 2017 only 79000 miles on it. All upto date changes regularly all. Other like Transmission oil changed all upkeep to date. Transmission needs rebuilt. We are in our 80’s And don’t beat up our cars. Replace or rebuild transmission 3500 to 4500 bucks. That is a lot of money for us. No longer covered. It shudders when you drive at any speed and feels so unsafe. Took it to GM garage and they couldn’t find anything wrong. No warning lights came on and we paid over 150 to have it checked out so with the shuddering getting worse and not feeling safe to drive we took it to a Transmission shop and he took it out and said the Shuddering was caused by something in the transmission. I have seen on google where GM is having a lot of problems in this area. We just need help with the repairs. Thank you. A retired GM worker Lordstown, Ohio [XXX].
