Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Radiator was drained, flushed and refilled with recommended dexcool coolant. Then started to leak about a pint a day. Dealer said that for $700.00 they can replace the plastic intake manifold gaskets (original equipment) with steel ones. On a limited income, I cannot have that done yet. I daily add a pint of coolant to prevent engine overheating. I have to clean my garage floor every morning from the leaking. *”
