Known issues on the 1990 Comanche. Two recalls are on federal record for this model year: a disc brake rotor whose cast iron wear surface can separate from the hub and reduce braking, and a cruise control fault where high engine idle when the vehicle is first placed in gear can cause unexpected acceleration. There are 15 owner complaints on record, and Jeep has issued 10 technical service bulletins for the year.

From a routine service interval to a brake overhaul or a hard-to-trace electrical fault, it keeps you on the correct factory procedure and specification for your specific 1990 Comanche.
