Known issues on the 1986 Seville. Three recalls are on federal record for this model year. The first covers replacement fuel filters that reached vehicles like this Seville: an improperly manufactured connector can keep the O-ring from seating correctly on the fuel line, creating an inadequate seal that can leak fuel and, near an ignition source, start a fire. The second covers the speed control linkage: a misplaced floor mat could keep the throttle from returning to idle, causing loss of accelerator control and a possible crash without warning. The third covers the Twilight Sentinel headlight switch, where a faulty potentiometer contact can create an intermittent circuit and cut the headlights and instrument panel lights out suddenly, reducing driver visibility. Owners have filed 13 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.
From a stuck-open throttle to an intermittent headlight circuit, it keeps you on the OEM procedure and the correct specification for your specific 1986 Seville.
