I own this 2015 Tahoe, it has 80,000 miles on it. While I was driving to work, the vehicle lost power as I was in the middle of major intersection. I was almost rear ended by another car. A few seconds later the car began going again. I had no service lights, no warning lights and no check engine light come on. It was running rough, lacking acceleration. I immediately brought it to my mechanic. They did they're testing and found Cylinder# 6 has collapsed. I was told that I will need a new engine at costs of over $8000.00. I have always maintained my vehicle and it's had regular oil changes every 4000 miles. In fact I'm still making car payments, and now I have to absorb this major cost of replacing an engine. When I looked on line to find some information of this Lifter problem, I found thousands of complaints of premature engine failures on these very expensive vehicles. …
My 2015 Chevrolet Tahoe with 90,000 miles needs a new camshaft and all 16 lifters need to be replaced. There was no forewarning about this huge problem. Literally, one day I was out in my car, and the accelerator suddenly stopped working for a while. Then, all of a sudden there was a hard jerk, and it sped up on its own. When I finally found a safe spot to pull over I went to push on the brakes and the entire car just started shaking. My poor children were terrified as this could've turned into a terrible accident for me and the other drivers around me. I immediately called my local mechanic and was told to bring it in immediately. On my way there the service indicator lamp came on. Upon inspection by my mechanic I was told I need a whole new engine. I have not had it repaired because I cannot afford to do so. …
I had noticed a slight smell of antifreeze/coolant occasionally when the vehicle had aroun42,000 miles. As a diesel engine technition I knew something was wrong.I found a slight leak in thr topleft corner of the radiator were the tubes go into the tank. Contacted GM and was told the radiator was not covered under the powertrain warranty. I would only have to add about a half a quart of coolant every service at 3,500 miles. Looking online I had seen bullitins on the 2014 chevy,gmc,and caddilac half ton trucks and suv's. Now at 77,000 miles its getting much worse and GM won't do anything about it. I have ordered a new Radiator and thermostat at an approximatley $300 dollars. I Know they have a bulletin PI1513A. But GM will not help. thank you.
