Known issues on the 1990 Wagoneer. Five recalls are on federal record for this model year: an anti-lock brake fault that can cause loss of the ABS function and reduced power-assist braking, a brake hose detaching from the ABS system and losing the hydraulic brake function, a disc rotor whose cast-iron wear surface can separate from the hub and reduce braking, hydraulic-fluid contamination that can make the anti-lock brake system malfunction, and a high engine idle when first placed in gear from the cruise-control system that can cause unexpected acceleration. Owners have filed 18 complaints and Jeep has issued 10 technical service bulletins for the year.

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