Burned oil from day one.
Never saw more than 22.5mpg out of this, Eco mode or not.
Timing chain replaced at 20,000 miles along with 8 total (half of the valves).
Driver seat lumbar broke not once but twice.
Made a weird pop noise when warming up from exhaust area, alternator seemed too weak for the car, high pressure fuel pump, pistons and rings replaced at 38,200 miles, car sold back to dealer after this replacement at 10 miles later.
Couldn't be happier to be out of that hell hole. Two engine tear downs at less than 4 years of age and 40,000 miles s. wow!
No more Chevy for us!
Stop making cars, request no more bail outs, allow yourself to fail GM.
Please don't put anyone else through this!
