Summary

Rear Trailing Arm Bolt Grease Certain 2016 model year Chevrolet Malibu model vehicles may have been built with grease applied to the trailing arm to knuckle attachment bolts. Grease added under the shoulder of the bolts could result in the bolts slipping over time. If the bolts loosen there would be an increasing amount of noise from the rear suspension. Left unaddressed, the upper bolts could potentially back out completely. This would result in a noticeable swaying of the vehicles’ rear end from road inputs while driving, and increased noise. The vehicle handling is not affected. Dealers are to replace the four rear control arm to knuckle bolts. It will also be necessary to clean any grease from the bolt mounting surfaces.

Owners of these vehicles have filed 19 complaints in the suspension category.
