1995-1996 Cavalier/Sunfire and the two-wheel-drive models of the 1996 Chevrolet S-10 and GMC Sonoma pickups with 2.2-liter four-cylinder engines.
Problem: Engine headgasket failures that include overheating, loss of coolant, the smell of coolant, coolant leaks around the cylinder head and white smoke from the exhaust. Sometimes the heater won't work or a film (from the coolant) will be deposited on the inside glass surfaces. If the coolant leaks inside the engine it can cause severe engine damage from overheating.
Warranty coverage: The 1995 and 1996 vehicles are now covered for headgasket problems for seven years or 100,000 miles (160,000 km), whichever comes first. Consumers who already paid for repairs at a dealership should contact the dealership to be reimbursed. Consumers who did not have a GM dealership do the work aren't excluded from the refund program and should contact the toll-free customer assistance number in the owner's manual. Future repairs, however, must take place at a GM dealership. The program is not a recall, and owners should take their vehicles to a dealership only if it appears they have a problem.
Remember, if you have an engine headgasket failure on a GM vehicle or engine not included in the above-noted programs, don't despair. Simply use the same benchmarks for your own vehicle and threaten small claims action on those grounds
