Known issues on the 1988 XJ6. Four recalls are on federal record for this model year. The brake accumulator switch can leak hydraulic fluid near wiring, interrupting electrical power and starving the brake power assist system, which can lead to loss of vehicle control. A separate recall covers the high-pressure fluid supply hose, which can rupture, draining the power assist system and risking an engine compartment fire from the expelled fluid. A brake lamp microswitch fault can knock out the stop lamps while also preventing cruise control from disengaging normally. The fourth recall covers the front suspension's lower spring pan fixings, which can fail from stress corrosion and let that corner of the car settle onto its bump stop. Owners have filed 13 complaints for the year, and the factory diagnostic and repair procedures behind each of those systems are here.

From a brake accumulator inspection to chasing a stop-lamp fault or a front suspension check, it keeps you on the OEM procedure and the correct specification for your specific 1988 XJ6.
