What Parts are Covered
The statute requires a dealer "to correct a material defect of the used vehicle." The statute also expressly covers:

The Engine - All internal lubricated parts, timing chains, gears and cover, timing belt, pulleys and cover, oil pump and gears, water pump, valve covers, oil pan, manifolds, flywheel, harmonic balancer, engine mounts, seals and gaskets, and turbo-charger housing. (Housing, engine blocks and cylinder heads are covered only if they are damaged by the failure of an internal lubricated part.)

Transmission Automatic/Transfer Case - All internal lubricated parts, torque converter, vacuum modulator, transmission mounts, seals and gaskets.

Transmission Manual/Transfer Case - All internal lubricated parts, transmission mounts, seals and gaskets, but excluding a manual clutch, pressure plate, throw-out bearings, clutch master or slave cylinders.

Front-Wheel Drive - All internal lubricated parts, axle shafts, constant velocity joints, front hub bearings, seals and gaskets.

Rear-Wheel Drive - All internal lubricated parts, propeller shafts, supports and U-joints, axle shafts and bearings, seals and gaskets.

The statute also says: It shall be an affirmative defense to any claim. . . that the alleged material defect does not substantially impair the use, value or safety of the used motor vehicle.
