Known issues on the 1989 Cutlass Supreme. Complaints to NHTSA about the 1989 Cutlass Supreme total 30, with hydraulic brakes and structure tied at 8 apiece and steering next at 4. Among them, 1 complaint reported a crash, 2 reported a fire and 1 reported a death. The 1 recall for this year concerned certain cars in heavy road-salt states, where corroded retainers could let the front engine cradle bolts pull free and, with both gone, the steering shaft could part from its gear; new cradle bolts and retainers were the fix. The manual gives procedures, torque values and specifications for the cradle, steering and brakes.
