NHTSA complaint #11364028, filed 2020-10, 150,000 miles“The engine coolant system clogged up my thermostat and coolant turned to a brown consistency and thickened like mud. Mechanic stated that the coolant, drex, can have no fluids added, and no water unless it is distilled. I did not add any coolant or water and received no coolant low warning.

NHTSA complaint #10573673, filed 2014-03, 80,000 miles“My Grand Prix recently started to display a message stating reduced engine power. It has been happening randomly for the past week. It only happens as I am driving the car. The car slows dramatically, and does not accelerate at all. As I was driving yesterday, I was merging into traffic where the speed limit is 45 MPH, I had more than enough room to merge into traffic, the reduced engine power message displayed and the car would not accelerate. The traffic quickly caught up to me and I was almost hit due to the car not accelerating. …”

This shuts down the power steering, brakes, etc. This has happened about a dozen times over the last year. All but two times when this happened, we were able to put the car in neutral and restart the car. Two of the times, the car did not want to start - car would crank but not start. Eventually we were able to get the car stated. Over the past year this happened when we were driving in a city at approximate 30 MPH, coasting down a hill, or stopped at a stop sign. …”
