Technical Service Bulletin P9242 2008-10 M — 2010 INFINITI M45

Expiration Notification – Wheel Valve Stem Nut Retailer Announcement ***** Campaign Summary ***** In 2009, INFINITI launched a Voluntary Service Campaign on certain 2008-2010 M35/M45 vehicles registered in states that do not use heavy concentrations of road salt in the winter, to replace the Tire Pressure Monitoring System (TPMS) nut with new, more corrosion resistant ones. INFINITI determined the material used in the nut on the M35/M45 that secures the TPMS sensor to the wheel, was not manufactured to specification and may corrode and potentially crack if driven regularly in areas where a heavy concentration of road salt is used during the winter. If this occurs, the nut may come out of the sensor causing the TPMS lamp to illuminate. If the TPMS lamp is disregarded, and the vehicle continues to be driven in this condition, the tire can quickly lose air pressure resulting in a flat tire. This customer service campaign and customer reimbursement for these repairs are no longer available. The expiration of this Voluntary Service Campaign has no effect on the status of Voluntary Safety Recall R0908. ***** What Retailers Should Do ***** 1. Service Comm will deactivate P9242 on any VINs on May 13, 2021. No further retailer action is required.
