Service campaign 25PBE

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

Parts and repair procedures are now available. Certain chassis may have a rear suspension tracking rod that interferes with the left rear brake valve components during full suspension travel. This interference could cause a loss of the rear service brake or ABS modulation for one rear axle wheel end, increasing the risk of a crash.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
