Service bulletin 122-C8R8N-05

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

Concerns: Tailpipe on exhaust system Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Tailpipe covers, whose durability cannot be guaranteed over the service life of the vehicle, were installed on the affected vehicles. The tailpipe covers can crack on vehicles with high mileage due to vibrations in the engine, particularly at high engine speeds. This can cause noises.
