EXTERIOR LIGHTING
REAR TAIL LIGHT ASSEMBLY (BOTH) CONNECTION TABS WHICH HOLD ASSEMBLY IN PLACE FAIL FOR NO REASON ALLOWING LIGHT ASSEMBLE TO FALL OUT. HAVE REPLACED THE REAR TAIL LIGHT ASSEMBLIES THREE TIMES. FIRST LIGHT ASSEMBLY FELL OUT AT 8 MONTHS AGE (APPROX 20,000 MILES), RETURNED TO DEALER THEY ADVISED ASSEMBLY MUST HAVE BEEN DAMAGED NO WARRANTY REPAIR. REPLACED BOTH WITH AFTER-MARKET ASSEMBLIES, 18 MONTHS LATER REAR LIGHT ASSEMBLY CONNECTION TABS FAILED. REPLACED WITH DEALER SUPPLIED PARTS (APPROX 75,000 MILES). NOW ABOUT 18 MONTHS LATER REAR LIGHT ASSEMBLY IS FAILING AGAIN (109,000 MILES). POSSIBLE CAUSE IS THAT PLASTIC TABS DO NOT SECURE LIGHT ASSEMBLE IN PLACE, ALLOWING NORMAL USE AND VIBRATION TO CAUSE CONNECTION TAB TO FAIL. *TR
