My check engine light and traction control light came on at approximately 157,000 miles. I was not safe. I was in the middle of the freeway. My Tahoe slowed and sputtered! I had to be towed. I got an inspection at Folsom Buick GMC in Folsom, CA at the recommendation of GMC General Motors Corporation. Fuel Injector #6 failed and required replacement. The dealership would not repair the fuel injector under the Special Coverage N182198000, stating your 7,000 miles over the special coverage. They wouldn't even provide a discount for the quoted $1832.00 dollar repair. Though General Motors Corporation sent me to their 3rd party partner for the inspection, they also refused to offer any help with my bill, further stating you're over the mileage. General Motors Corporation also sent out bulletin 11-00-89-005W, where it specifically states dealers are required to use the Policy Evaluation Tool and are encouraged to follow the recommended amount of GM participation towards the repair cost, and they failed to honor their own bulletin and product.

Purchased 2017 Chevrolet Tahoe on 1/15/2025 with 50,647 miles on it. At exactly the 40 day mark, we noticed a problem when the vehicle began downshifting. When slowing down to stop at a red light, we could feel the transmission begin jerking as it shifted down and the check engine light came on. It has been taken back to the dealership (where we bought it), 5 times as of yesterday and they cannot fix the problem. The engine idles rough, downshifting is extremely hard, check engine comes on and off sporadically. The transmission temperature goes up and the dashboard lighting dims intermittently. This vehicle appeared to be in extremely good physical condition with very few miles, that's why it was purchased.

He said the torque converter broke into pieces and traveled through my transmission lines. Online I learned this wasa very common problems with these kind of trucks and suvs.
