I bought the truck around [XXX] from Barkau CDJR, Freeport IL. Two hours away from the dealer the truck went completely dead in traffic. A message appeared on the info screen that said roll down the drivers window and back up to reset the system when the truck finally restarted. Got home with it and called the dealer and let the know. In the next few weeks it happened a couple of more times. It was taken to Tapper Chevrolet in Paw Paw, MI to be serviced. The tech thought it was a problem in the fuse Block and replaced that, after that on the week end the truck was returned the problem happened 3 times. Took it back to Tapper's and they checked it again, had it for 4 days and could not replicate the problem. Kept having issues and took it to 1st Choice Automotive LLC in Dowagiac, MI, he went through the wiring and cleaned some grounds and it seemed to work for a while. Now it is doing the same thing again. It just shuts down randomly for no reason. You lose steering, brakes, you have no control when it happens and no warning when it is going to happen. Have searched You Tube and have seen many other complaints of the same problem with no solution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

With only 32,000 miles the active fuel management system went out. The lifters failed and caused internal engine damage. My vehicle was well maintained using only high quality synthetic motor oil. I am on the hook for over $5000 in engine repairs. This technology was a miserable failure and the consumer should not be held responsible for poor engineering.
