: the contact stated while traveling 60 mph on normal road conditions, the vehicle's engine began to misfire. The vehicle was taken to an authorized dealer, who determined that cylinders 1, 3, and 5 were misfiring, and that the spark plugs needed to be replaced. A radiator, coolant, ac blower fan, and spark plugs were replaced, which corrected the problem. A week after the repairs, the ac blower fan stopped functioning, and the vehicle was taken back to the dealer. Upon inspection, it was noticed that coolant was dried on the top of the radiator and cap. The dealer determined that coolant overflowed. The misfiring problem recurred 2 & 1/2 weeks after the first repair, and was taken back to the dealer. It was noticed that coolant was found inside the ports, and the heads on the engine were warped. Also, it was determined that new heads would have to be installed to correct the problem. The paperwork stated exhaust fumes were found inside the cooling system. The contact planned to contact the manufacturer after filing a complaint with the NHTSA.
