Service bulletin A421420 2036991-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Customer hears squeaking, clunking, or rattling noises from the rear of the vehicle when it is driven over bumps. This condition may also be identified at PDI. The rear buffer stop may be out of place or require lubrication. In an effort to gain information regarding this condition, we request that you contact the Technical Assistance Center (TAC) before performing any repairs.
