Service bulletin 122-A4M7P-08

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

"OBSERVATIONS HAVE SHOWN THAT THE CHASSIS STILL SHOWS A CERTAIN AMOUNT OF SETTLING BEHAVIOR WITHIN THE FIRST 3,700 MILES (6,000 KM). DURING PERFORMANCE-ORIENTED DRIVING ON A RACE TRACK – PARTICULARLY IF THE VEHICLE IS FREQUENTLY DRIVEN AT ITS PERFORMANCE LIMITS – COMBINED WITH CHASSIS SETUP TOLERANCES, THIS CAN QUICKLY CAUSE THE WHEELS TO COME INTO CONTACT WITH PERIPHERAL COMPONENTS."
