# Service bulletin 25KWA

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

Safety Recall – Interim Notification Certain vehicles may have an oversized magnet carrier in the throttle pedal assembly. The magnet carrier acts as the pivot for the throttle pedal. An oversized magnet carrier may cause the throttle pedal to stick. If the throttle pedal fails to return to idle, or sticks, it may increase the risk of a crash. Drivers may feel sticking or that the pedal doesn’t return to idle once released. Pressing the service brake will overcome a stuck throttle pedal and allow the vehicle to stop. This bulletin will be updated when parts and procedures are available.
