While traveling eastbound on interstate 10 from van horn to fort stockton at approximately 85 mph with a semi parallel on the right hand lane and an SUV directly behind me no more than 3 car lengths away, the check engine light activated and all power was lost. When the engine shutdown luckily the SUV behind me was able to slow down after I immediately activated my emergency flashers and I was able to safely, after almost causing an accident, move over to the right hand shoulder/grass area. After having truck towed to the nearest chevy/gm dealership in pecos TX, the diagnosis was a faulty fuel pump estimated cost over $800. This is a serious safety issue when traveling on the highway and the fuel pump goes out and should be looked at by NHTSA.
The truck is less than 3 yrs old with only 23671 miles. Check engine light came on. P050d code and the transmission began to down shift hard at times when slowing down. Dealer said there was carbon build up on cylinder 1 valves that caused them to stick and a misfire. I found it interesting that cylinders 1-4-6-7 are the cylinders that shut down for afm active fuel management system when it goes into v4 mode. Dealer said it was not related. Said it was poor fuel. Said I need to run top tier detergent from select gas stations. That is the first time anyone has told me this. That's not in the owners manual and no one told me I would need to use special gas stations when I bought the truck brand new. I then told him the two stations I use are mobil and sunoco. Both of which are on the top tier fuel distributor list. Interesting fact: top tier fuels is a registered trademark of general motors. They failed to mention that when they told me about my "poor fuel" which is apparently a licensed gm product. I was told if this happens again I would have to pay as it would likely be outside the bumper to bumper warranty period (36 mos). Apparently the fuel system is not part of the power train? found nothing with the transmission. Not surprised. Last new Chevrolet I will ever buy.
