Known issues on the 1991 S15 Jimmy. Five recalls are on the federal record. Fasteners at the lower control arms, rear spring shackle and rear shocks could strip under load and let a control arm pull free; the wrong primer under the windshield and side glass could leave the bonding too weak to hold glass in a crash; and cooling fan blades could fatigue and break apart under an open hood. Two more concern lamps built without the required amber side reflectors. Nine owner complaints are logged, seven of them on the service brakes and two on seat belts, which the brake and suspension sections here address.
