NHTSA complaint #8002519, filed 2002-01“The check engine and low coolant lights appear often and the engine idles at an abnormal setting. Which causes the engine to run warmer than it should and causing the brake pads to be replaced long before they should be. As for the low coolant light, there is not a need to add coolant because its just a little less than full. And as for the high idle, the car has accelerated at times by its self to 45 MPH.”
