I WAS IN A SEMI V CAR ACCIDENT WEDNESDAY NOVEMBER 19TH, ON A 4 LANE MAJOR HIGHWAY (I-294). I WAS DRIVING A 2004 CHEVY AVEO. I WAS CUT OFF BY THE SEMI AND MY CAR WAS HIT, SPUN OUT OF CONTROL THROUGH 3 LANES OF TRAFFIC AND HIT THE CENTER MEDIAN OF THE HIGHWAY. THE CAR IS TOTALED. THE ENTIRE ENGINE BLOCK WAS SMASHEDINWARD. MY AIRBAG DIDN'T DEPLOY. I'M ANGRY. THIS CAR HAS HAD NOTHING BUT DEFECT AFTER DEFECT, BUT I PAID FOR A SAFETY FEATURE THAT WAS FAULTY. I WALKED AWAY FROM THIS ACCIDENT, BY THE GRACE OF GOD, AND NOW AM SUFFERING HORRIFIC PAIN THAT IS DIRECTLY INFLUENCED BY MY AIRBAG NOT DEPLOYING. I HAVE NO RECOURSE TO TAKE AGAINST CHEVY. I WANT DOCUMENTATION OF THIS MAJOR FAILURE. I'M LUCKY I DIDN'T DIE. THE SEMI WAS TICKETED IN THE ACCIDENT. *TR

WHILE STOPPED AT RED LIGHT, OUR 2004 CHEVY AVEO WAS STRUCK FROM BEHIND BY A VEHICLE TRAVELING ABOUT 25-45 MPH, WHICH PROPELLED THE AVEO INTO THE CAR IN FRONT OF IT. DURING THE CRASH, THE DRIVER'S SEAT MOVED BACKWARD INTO ABOUT A 45 DEGREE ANGLE AND LOCKED IN THAT POSITION AND PROVIDING MY DAUGHTER NO PROTECTION AGAINST WHIPLASH. SHE RECEIVED INJURIES TO HER NECK AND ABDOMEN, WHICH WOULD HAVE BEEN MUCH WORSE IF SHE HAD NOT BEEN HOLDING ON TIGHTLY TO THE STEERING WHEEL. SHE WAS WEARING HER SEAT BELT AT THE TIME OF THE CRASH, AND THE AVEO AIRBAGS DID NOT DEPLOY. *JB

ACCORDING TO MAINTENANCE SCHEDULE AT 45000 KM SERVICE SHOP HAD TO INSPECT EVAP CONDENSER FROM THE CONDITIONING SYSTEM AND THE PIPELINES. AC PERIODICAL MAINTENANCE NEVER HAD BEEN PERFORMED TO THE VEHICLE AS IT WAS STATED IN THE TECHNICAL SPECIFICATIONS. 5.ENGINE OIL WAS NOT THE RESPECTING API SPECIFICATIONS SO INSTEAD 5W 30 SYNTHETIC OIL WAS USED 10W 40 MINERAL OIL. IT TOOK ALMOST 18 MONTHS AND 40603 KM TO CONVINCE THEM TO USE THE PROPER OIL FOR THE ENGINE. THIS THING AFFECTED ENGINE LIFE. *JB UPDATED 07/17/2012 *JS
