Service bulletin 122-M4K7W-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: Front level sensors, left and right Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. It is possible that the sensors for the levelling system on the front axle of the relevant vehicles may be damaged or incorrectly positioned in relation to the control arms. If a sensor is damaged, a fault entry may occur in the PASM control unit over the service life of the vehicle and, as a result, a "Chassis system fault" warning message may appear in the instrument cluster. This fault type may occur after only a short time if a sensor is incorrectly positioned.
