Example complaints
Engine: “Occasionally there is a loud sound in the cabin of water sloshing back and fourth under the dashboard. Some days it will happen when the engine starts. Other times, it is after driving several miles. Sometimes it happens a few days in a row. Other times it will go a week with no noise. The GM mechanic verified that the coolant level is fine. It happens when the car is stationary or moving. I have not heard it at high speeds.”

Several indicators displayed at the time, including: • Service Engine • Service Stabilitrak • Service Antilock Brakes • Service Transmission I managed to pull the car to the side of the road and restart it, but it was stuck in first gear. After several restarts it performed normally. I took the car to Miller & Sons, they told me they could not find a code and the car was performing normally at that point so there was nothing they could do. …”
