CAR RUNS GREAT UNTIL CHECK ENGINE LIGHT COMES ON FOLLOWED BY VSC AND THEN BRAKE LIGHT. WHEN THOSE LIGHTS COME ON IT RUNS ROUGH AND BRAKES MAKE GEAR NOISE UNDER DRIVER'S SIDE HOOD AREA. BRAKE IS VERY SLUGGISH AND ALMOST NON EXISTENT WHEN IT FAILS. LET IT SET, CLEAR FAULT AND RUNS FINE UNTIL WARM AGAIN. HAVE HAD ALL BRAKES CHECKED AND IN GOOD CONDITION BY MECHANIC TODAY AND PROBLEM PERSISTS. APPEARS TO BE AN ECU OR OTHER ELECTRICAL AND NOT MECHANICAL PROBLEM. IS EXTREMELY DANGEROUS AND SHOULD BE ADDRESSED BY MANUFACTURER.

THE PASSENGER SIDE AIRBAG WARNING LIGHT ON MY VEHICLE TURNED ON. WHEN I TOOK MY VEHICLE TO LEXUS FOR A RECALL I HAD THEM CHECK WHY THE LIGHT WAS ON. THEY TOLD ME THE AIR BAG WIRING HARNESS NEEDS TO BE REPLACED AT A COST OF $2546. THEY ALSO SAID THIS IS A COMMON ISSUE THAT LEXUS IS WELL AWARE OF AND ISSUED A TSB FOR IT IN 2008 BUT WOULD ONLY COVER THE REPAIR UNDER THE INITIAL WARRANTY PERIOD BECAUSE THEY HAD NOT RECEIVED ENOUGH COMPLAINTS TO MAKE A RECALL. WELL NOW 6 YEARS AFTER THEY ISSUED THE TSB I'M SURE THERE HAS TO BE ENOUGH COMPLAINTS …

THE AIRBAG LIGHT IS NOW CONSTANTLY DISPLAYING RED ON MY DASHBOARD. NALLEY LEXUS OF SMYRNA GA STATED THAT THERE IS A SHORT IN THE WIRE HARNESS AND IT NEEDS TO BE REPAIRED AT A COST OF $3300 OR THE AIRBAGS WILL NOT WORK IN THE EVENT OF A CRASH. FROM READING ONLINE IN THE LEXUS OWNERS BLOGS, THIS IS VERY COMMON AND I HAVE READ IN THE FORUMS THAT LEXUS, IN 2006, 2007, INSTALLED A WIRING HARNESS THAT WAS TOO SHORT. THE HARNESS PLUGS BECOME LOOSE AND IN SOME CASES THE WIRE INSULATION BECOMES CHAFED AND SHORTS OUT THE AIRBAG SYSTEM. I AM NOT AWARE W…
