Known issues on the 1990 300SE. NHTSA filed one recall against the 1990 W126-chassis models. It covered certain cars whose brake strut support bolts fell short of specification and could fracture, degrading steering and braking and risking loss of control; bolts meeting the standard were installed. The 1990 300SE has one owner complaint, which concerns the engine and engine cooling. Suspension and brake strut torque values, as well as cooling system procedures, are included in this manual.
