Defect

06V395000LightingOctober 13, 2006 · 1,863 units

Defect

CERTAIN VEHICLES FAIL TO COMPLY WITH THE STOP LAMP AND REFLEX REFLECTOR REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, 'LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT."

Consequence

THIS STANDARD IS TO REDUCE CRASHES, INJURIES AND DEATHS BY PROVIDING ADEQUATE ILLUMINATION OF THE ROADWAY, AND BY ENHANCING THE CONSPICUITY OF MOTOR VEHICLES ON THE PUBLIC ROADS SO THAT THEIR PRESENCE IS PERCEIVED AND THEIR SIGNALS UNDERSTOOD, BOTH IN DAYLIGHT AND IN DARKNESS OR OTHER CONDITIONS OF REDUCED VISIBILITY.

Remedy

DEALERS WILL REPLACE THE REAR COMBINATION LAMP ASSEMBLIES FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN ON OR ABOUT APRIL 16, 2007. OWNERS MAY CONTACT INFINITI AT 1-800-662-6200.

Defect

THE LOWER ANCHORAGE BRACKETS IN THE REAR SEATS DO NOT MEET THE LOCATION REQUIREMENT IN THIS STANDARD. THIS MAY CAUSE DIFFICULTY IN ATTACHING SOME CHILD SEATS TO THESE BRACKETS.

Consequence

IF A CHILD SEAT IS NOT SECURED, THERE IS AN INCREASED RISK OF INJURY IN A CRASH.

Remedy

DEALERS WILL REPLACE THE LOWER ANCHORAGE BRACKETS WITH MODIFIED ONES TO ENSURE THAT THE STANDARD IS MET. THE RECALL BEGAN ON OCTOBER 17, 2005. OWNERS MAY CONTACT INFINITI AT 1-800-662-6200.
