Service bulletin 122-T8T7L-12

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

Subject: Bleeder screw for front axle lift system Situation: There is a possibility that the bleeder screw for the front axle lift system was not tightened to the prescribed tightening torque on the affected vehicles. This can impair the function of the lift system. The error message "Error lift system" can then be displayed in the instrument cluster when the lift function is activated.
