2008 Chevrolet Trailblazer Airbags Problems

Both side curtain airbags deployed while driving down the street. The driver's seatbelt tightened then locked up. There was no obvious reason for the airbags to deploy. the vehicle was taken to a Chevy dealer to see if it was on recall list but they said it was not. Vehicle was referred to a body shop for estimate for repairs...$6,435.00....if you can find the parts. driver was shaken up by the deployment but not injured.

MY AIRBAG LIGHT CAME ON. CALLED THE DEALER. BROUGHT IN THE NEXT COUPLE OF DAYS. THEY SCANNNED CODES (OUR TPS) LIGHT HAD BEEN ON. FAULTY PPS AIR BAG MODULE $1150.00 TO FIX IT. TOLD THEM GO AHEAD. WHAT COULD I DO, THIS IS THURSDAY. THERE WAS NO SENSOR TO BE FOUND, THEY SAID GM HAD A BACK ORDER OF THIS PART, WENT HOME (SLOWLY) THE DEALER SAID THEY WOULD CALL ME ON FRIDAY. CALLED THE DEALER SAID THEY LOCATED ONE IN KENTUCKY. I ASKED IF THEY COULD GET IT OVERNIGHT, TO WHICH THEY SAID NO. MY CONCERN IS IF AIRBAGS ARE SO IMPORTANT FOR 'SAFETY" PARTS READILY AVAILABLE PARTS SHOULD BE WITHIN A 24HR RANGE. SAFTETY IS MY CONCERN. TOLD THE DEALSHIP THAT WE WERE VERY SCARED AND UNHAAPPY. MAYBE ITS TIME TO LOOK AT OTHER CARS THE GMC IS NOT WHAT THEY USED TO BE. THEY SHOULD BE HELD ACCOUNTABLE. I HOPE NO ONE GETS HURT WITHOUT AN AIRBAG.

ENGINE DIES WHILE DRIVING (LOSING PROPULSION, STEERING, BRAKES, ETC.) AND THE KEY WILL NOT RESTART WHEN TURNED FORWARD (IN NEUTRAL), WHILE COASTING, BUT WILL RESTART WHEN THE KEY IS TURNED BACK AND THEN FORWARD AGAIN. IN THIS CASE, COASTING DOWN AND BRAKING AND TURNING RIGHT, POSSIBLY WITH RIGHT TURN SIGNAL ON. DIED RIGHT BEFORE STARTING TO TURN THE STEERING WHEEL AT ABOUT 15-20 MPH. IT WAS A CLEAR DRY 100 DEGREE AFTERNOON, ON SMOOTH PAVEMENT. WE LIVE ON A BUMPY DIRT ROAD THAT IS JUST OVER A QUARTER OF A MILE LONG TO REACH OUR HOUSE. SIMILAR TO OTHER GM IGNITION KEY / NO AIR BAG RECALL PROGRAMS FOR SIMILAR MODEL YEAR VEHICLES, SUCH AS THE HHR. THERE IS NO RECALL, BUT HOW MANY PEOPLE DOES THIS HAPPEN TO? ANY DEATHS, YET? I DON'T BELIEVE THE AIR BAGS MAY HAVE WORKED, SHOULD WE HAVE BEEN INVOLVED IN AN ACCIDENT. THERE WAS NO INFORMATION SHOWN IN THE DIVER INFORMATION CENTER DISPLAY (DIC) AND THERE WERE WARNING LIGHTS ON IN THE DASHBOARD, TO INDICATE THAT THE POWER WAS ON TO THE INSTRUMENT CLUSTER (IC), BUT THAT THE MOTOR WAS OFF. I COULD NOT SELECT BRAKES AND STEERING AS BEING AFFECTED, BUT WITH NO MOTOR, THERE IS NO VACUUM BRAKE BOOSTING GOING ON, AND NO POWER STEERING EITHER.

DURING A LEFT HAND TURN, THE SIDE AIRBAGS AND FRONT SEATBELT DEPLOYED FOR NO REASON. AFTER A COMPLETE DIAGNOSTIC BY GM THEY CONCLUDED THE COMPUTER SENSED A ROLLOVER AND THE AIR BAGS WERE DEPLOYED ON COMMAND. PROBLEM IS THAT THE TILT OF THE VEHICLE DID NOT REACH OR EXCEED 20 DEGREES (ONLY 2 DEGREES) AND THEREFORE THE SYSTEM SHOULD NOT HAVE DEPLOYED. THIS WAS VERIFIED BY GM'S OWN REPORT YET THEY DENIED ANYTHING WAS WRONG. *TR

WHILE I WAS DRIVING DOWN THE ROAD, BOTH CURTAIN SIDE AIR BAGS DEPLOYED AT SAME TIME. THERE WERE NO OTHER CARS ON THE ROAD, SO I WAS ABLE TO STOP THE VEHICLE WITHOUT CAUSING AN ACCIDENT. THE AIRBAG ON THE DRIVER SIDE PUSHED ME OVER SO HARD THAT IT BROKE MY CENTER CONSOLE. MY LOWER BACK STILL HURTS, BUT I AM HOPING THE PAIN WILL GO AWAY. MY LEFT EAR IS STILL RINGING AND HAS NOT RETURNED TO NORMAL HEARING YET CAUSED FROM THE EXPLODING NOISE FROM THE AIRBAG DEPLOYMENT. BOTH OF THE FRONT SEAT BELTS WILL NOT WORK AND THE DASHBOARD HAS SO MANY LIGHTS GOING OFF, I DON'T KNOW IF THERE ARE ANY OTHER PROBLEMS. THE DEALERSHIP THAT I PURCHASED THE VEHICLE FROM SAID THE DAMAGES COULD RUN AS MUCH AS $4000.00 WHICH I DO NOT HAVE AND MY INSURANCE DOESN'T COVER THIS SINCE THERE WAS NO ACCIDENT THAT CAUSED THIS. THE DEALERSHIP SERVICE DEPT. ALSO SAID THEY HAVE NEVER HEARD OF ANY VEHICLES DOING THIS. AFTER RESEARCH, I SEE THAT THIS HAS HAPPENED ALOT. *TR

MY DAUGHTER TRAVELING AT APPROXIMATELY 55 MPH, SAW CAR IN FRONT OF HER STOPPED AT A STOP LIGHT. SHE ATTEMPTED TO SLAM ON THE BRAKES, IT FELT AS IF SHE WAS NOT STOPPING AT ALL. SHE HIT THE STOPPED CAR, PUSHED BOTH OF OUR CARS THROUGH THE INTERSECTION TO THE OTHER SIDE. HER AIRBAG DID NOT DEPLOY, ONSTAR DID NOT CONTACT HER. THE REASON I BOUGHT THIS SPECIFIC CAR WAS FOR THE ONSTAR IN CASE OF A COLLISION OR EMERGENCY. WHEN I CONTACTED ONSTAR LATER, THEY REPORTED THEY DID NOT RECEIVE NOTIFICATION THAT A COLLISION HAD OCCURRED. I CONTACTED GM TO HAVE BRAKE, AIRBAG, AND ONSTAR FAILURE INVESTIGATED. RECEIVED REPORT FROM GM INVESTIGATOR STATING NO FAILURE IN AIRBAG SYSTEM, THAT THE CRASH WAS NOT SIGNIFICANT ENOUGH TO CAUSE AIRBAG DEPLOYMENT AND ONSTAR NOTIFICATION. SHE WAS TRAVELING 45 MPH UPON IMPACT (PER CDR). THE CAR WAS TOTALED - OVER $13,000 DAMAGE. IF A CRASH AT 45 MPH, REAR-ENDING, CAR TOTALED DOES NOT DEPLOY AIRBAGS IT SEEMS AS THOUGH SOMETHING IS WRONG. *TR

WHILE DRIVING ON A STRAIGHT SECTION OF A CITY STREET AT ONLY 30 MPH BOTH SIDE CURTAIN AIRBAGS DEPLOYED. I WAS STARTLED BUT QUICKLY LOOKED AROUND TO SEE IF I HAD HIT ANYTHING OR HAD BEEN HIT BY ANOTHER CAR. I WAS STILL MOVING FORWARD AND AS SOON AS SAFELY POSSIBLE PULLED THE CAR OVER AND GOT OUT TO INSPECT WHAT HAD HAPPENED. THERE WAS NO COLLISION WITH ANY OTHER OBJECT OR CAR AND THE AIRBAGS HAD DEPLOYED WITHOUT WARNING. THE AIRBAG LIGHT HAD NOT BEEN ON AND THE CAR WAS DRIVING NORMALLY. I CALLED MY INSURANCE COMPANY AND REPORTED THE INCIDENT AND REQUESTED A TOW. THE INSURANCE ADJUSTER HAS SINCE DETERMINED THAT SINCE THERE HAS BEEN NO COLLISION THAT THE CAUSE MUST BE FROM A MANUFACTURER'S DEFECT. THE BODY SHOP HAS RUN THE CODES FROM THE ON BOARD COMPUTER AND THEY ARE B0051,B0058,B0062,B0065,B0070, AND U7300. EXCEPT FOR THE U7300 THE REST ARE STATING THE OBVIOUS THAT THE AIRBAGS AND SEAT BELT TENSIONERS HAVE DEPLOYED. THIS IS A VERY SERIOUS SAFETY CONCERN BECAUSE IF I HAD BEEN DRIVING AT HIGHWAY SPEEDS ON A SECTION OF ROAD THAT WAS CURVED I DO NOT THINK THAT I COULD HAVE MAINTAINED CONTROL OF THE VEHICLE. *TR

DRIVING AT 45MPH AND HIT A POTHOLE, BOTH SIDE CURTAIN AIR BAGS DEPLOYED. TOOK TO DEALER AND THE TECH SAID THERE IS NO DAMAGE TO TIRES, WHEELS OR SUSPENSION SO THAT JUST DOESN'T HAPPEN. IT WILL HAVE TO BE AN INSURANCE CLAIM BECAUSE YOU WERE DRIVING AT THE TIME. TALKED TO THE SERVICE MANAGER AND HE SAID THERE ARE SCUFFS ON THE TIRES AND RIMS AND IT WAS ENOUGH JOLT TO SET OFF THE AIRBAGS SO THEY WERE WORKING AS DESIGNED. IT WILL HAVE TO BE AN INSURANCE CLAIM. *TR

THE INCIDENT HAPPENED EARLY IN THE MORNING ON THE WAY TO WORK. AS I WAS DRIVING, I CAME TO A RED LIGHT AND MADE MY RIGHT HAND TURN LIKE I ALWAYS DO. I STARTED DRIVING DOWN THE ROAD, AND MY SIDE AIRBAGS DEPLOYED ON BOTH SIDES. IT SCARED ME & MY DAUGHTER SO BAD, AND IT CAUSED ME TO SWERVE AND HIT THE CURB ON THE LEFT SIDE. LUCKILY THERE WERE NO CARS AROUND ME. I DON'T KNOW WHY THEY DEPLOYED LIKE THEY DID. THIS IS VERY DANGEROUS!! IT NEEDS TO BE LOOKED INTO BY THE FACTORY!!!!! *TR
