Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I took my car in for a 60,000 mile check-up and was astounded to learn that the head gasket was leaking at only 57,000. I could not afford the repair at this time and the mechanic said that nothing was leaking that would hurt the engine, but it should be taken care of soon. In all the years I've had a car I've never had a leaking head gasket and at 57,000, too. My last car, also a Plymouth, had over 127,000 miles on it and I never had problems with the engine. I do not misuse my vehicle, I have the oil changed every 3 to 6,000 miles and do everything possible to keep it trouble free.”
NHTSA complaint #10070013, filed 2004-01, 52,000 miles“Head gasket replaced, then it lost all power, and engine service light came on. I took it back, they said it needed spark plugs. I have it back, but it is still missing and I am not convinced that my problems are over.”
NHTSA complaint #760520, filed 2002-04“Oil light came on. Check my oil and it was totally empty. Took it to the dealership because I knew there was a problem since it was not time for oil change. Stated that my head gasket went out.”
