Unfortunately, it is fatal if you just keep driving it, and they are 100% GM. That is probably the problem. If they were Nissan, they would last longer...LOL.
I'm tired of the ignorant comments. "If it was Nissan it would last longer". I'm never buying GM again" I knew what I was going to see when I opened this thread. You never disappoint. I'm going to give you some common sheep like advice. Go buy an Asian brand. They never have problems. The service departments at their dealers are going out of business because Asian vehicles are "BULLETPROOF" and they have no customers for repairs. It's like my Uncle. Tells me I'm lucky to have 160,000 Chevy. The next week, his brand new Nissan is leaving their driveway on a flatbed. I despise this bias toward American vehicles [censored]. Sick people, no pride.
I was as loyal to American made as it gets, having purchased 13 new American made vehicles in 30 years of driving. each vehicle ownership experience was worse than the one before. Each F150 I bought got worse mileage then the one before, and had more issues that Ford refused to acknowledge, until warranty was expired. My 2010 F150 had the blend air door actuator fail before the first set of brake pads wore out. I may be picky, but I believe my heating system should outlast the first set of brake pads. The original quote to fix the blend air door actuator was $1,200.00, I had to fight for a year (without heat or A.C.) to get any help from Ford, and still ended up paying several hundred dollars to replace a part that is a known failure fleet wide, from F150s to Lincolns.
There was my one experience with GM, a 1999 Silverado that was dead on the side of the road driving it home from the dealership the night I bought it. That was just the beginning of a 50,000 mile ordeal that involved three transmissions, a transfer case, and the rebuilding of both differentials. In the end, with the truck torn apart at the dealership, GM said they would pay for no more repairs, and offered me 10% off MSRP of the GM vehicle of my choice. I had never used 4X4 yet the front differential bearings failed, what a joke.
After blowing hundreds of thousands on American *rapmobiles, I final bought a Toyota. I am really upset with myself for not having made the switch 20 or 25 years ago.
Keep blowing your horn about American cars, and keep your checkbook handy for the next big *crew you from GM or Ford.
