This vehicle has a problem with their lifters in the motor. It breaks down and you cause your engine to start shaking and makes a click sound like if its rubbing to something in the motor to cause a future problem in the motor and Engine light comes on. Many people have experienced this same problem with this make and model. My left lifter when out and they fixed it but what about my right lifter why didn't they replace the right lifter. This is a problem that Chev knows, and they have not recalled the lifters. Chev going after the company that made these lifters, so they know it's a problem why hasn't this been recalled? What if I was on a long road trip when this happens. This could blow out the motor and I could be stranded in the middle of now where if this happens.
