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.

The transmission dropped 2 thousand miles over my warranty at 102k miles. I was taking my son to see his surgeon and the car started jerking and making noises in the middle of a busy intersection. We almost got hit several times trying to get it to the side of the road for safety. I had to pay almost $1800 to get it towed home (we were in Peoria about 150 miles from home to see his doctor). There were no indications the transmission was going out and never should have at that mileage. I always do regular maintenance and keep all my receipts. I then paid 6k out of pocket to have it replaced with a better transmission since I learned GM put a bad transmission in the Tahoe I have (I was told I missed the time limit to have it fixed on their dime). Then 6 weeks later a fuel injector and the lifters failed due to the active fuel management. No one was hurt thankfully because I was just leaving home to go to work when I noticed the tapping sound and had my mechanic come look at it. Him and 2 other mechanics confirmed it was the lifters. I had already borrowed money to replace the transmission and can’t afford the $12k quote to fix it. Now it has been sitting in my driveway for almost a year unable to be driven. It is however causing me severe depression. I’m borrowing my son’s car while paying almost $700 monthly on a Tahoe I can’t even drive. I was even more sad when I found out there’s thousands of people with the same issue. GM should be ashamed of themselves!
