Known issues on the 1990 Suburban. Four recalls appear on the federal record for this year. Two of them reach the driver during a stop: rotors that can separate where the stamped center and cast outer sections corrode at their joint, and a seat recliner joint whose bolts loosen and fatigue until the backrest can fall rearward. The others cover transmission fluid vented out under heat near an ignition source, and a replacement fuel filter that can leak at its connection. Of 65 complaints, seats draw 17, tires 12 and the service brakes 11, all systems specified here.
