NHTSA Complaint #11711865 — 2020 CHEVROLET TAHOE

I sent this to GM Corporate on 2/12/2025: I'm writing regarding the recall on certain 2020 Chevy Tahoe transmissions. My husband is meticulous with his vehicles including all regular service updates and recommended appointments. It literally looks like it came off the showroom floor 5 years after buying it. Unfortunately, when returning on a trip our vehicle suddenly increased rpm's and wouldn't respond while going 65 miles per hour. Thankfully, it reengaged, and we were okay but imagine what could have happened! We managed to get it home, but while attempting to back up it wouldn't shift. We had to have it towed and have been told our transmission is SHOT! It will cost us over $7000 to replace?!! We attempted to call the GM customer service number to Complain and see if they could provide some help. They put us in touch with a service manager in our area whose voicemail was full and took a week to connect with. She basically said there is nothing she can do as it is within the 5 years but over on miles. So, here we sit with a vehicle we have babied for 4.9 years that needs a new transmission. I am asking for you to listen. Asking for you to expand the investigation/recall to include ALL 2020 (or related) vehicles. Something isn't adding up, and you are leaving customers who have paid off their $60,000 vehicle stuck with more $$ to pay because of an about defect. This could have killed us. It literally froze while we were driving, and now we are without a vehicle waiting for a new transmission. We have never had issues with the transmission before. How does a transmission just go? Definite defect!
