Vehicle speed control
Fuel injection system reconfiguration to comply with engine emission standards cause higher engine vibration levels which lead to early wear and complete failure of the secondary throttle return mechanism.
Remedy: A new production secondary throttle return system configuration will be installed.

Linkages (visibility)
A tolerance mismatch in the crank assembly of the bosch windshield wiper motor could cause instantaneous separation of the crank from the linkage assembly in the left hand control arm assembly; this would make the system inoperable.
Remedy: Replace left hand control arm linkage assembly.

Interference between steering gear sector shaft and the frame rail through hole can cause sector shaft wear and can weaken shaft cause it to break.

Is the recall repair free?

What is the difference between a recall and a complaint?
A recall is a safety campaign filed by the manufacturer or ordered by NHTSA, with a defined defect and remedy. A complaint is a report an owner sent to NHTSA; it is not verified, but patterns of complaints are what trigger NHTSA investigations and, eventually, recalls.
