TAKATA RECALL ? AIR RIDE SUSPENSION FAILURE, OVER INFLATION RESULTING IN A EXCESSIVE BOUNCING RIDE AND LOSS OF TRACTION ON OTHER SITES I SEE THAT THIS WAS A 92% COMPLAIN RATE
INFLATOR STOPPED WORKING, AIR BAG BLEW OUT WHILE ON FREEWAY!
THE REAR END BEGAN DEFLATING AFTER SITTING OVERNIGHT. AT FIRST IT WOULD AIR BACK UP WHEN STARTED IMMEDIATELY. THEN IT BEGAN TO TAKE A LONG TIME TO AIR BACK UP. IT RECENTLY BEGAN DEFLATING ALL OF THE TIME, EVEN WHEN DRIVING. NOW IT WILL NOT AIR UP AT ALL. THE MOTOR RUNS BUT NOTHING HAPPENS. THE VEHICLE HAS BEEN SERVICED BY THE DEALERSHIP TO NO AVAIL. EACH TIME, THERE IS SOME NEW REPLACEMENT PART THAT MUST BE PURCHASED. THIS IS A SAFETY HAZARD AND THE MANUFACTURER SHOULD RECALL THIS VEHICLE. *TR
TL* THE CONTACT OWNS A 2006 GMC ENVOY DENALI. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 25 MPH, THE REAR END OF THE VEHICLE DROPPED DOWN TO THE AXLE. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS. THE MECHANIC STATED THAT THE REAR END AND THE AIR SUSPENSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 143,612.
1. STARTED WITH HORN HONKING ON ITS OWN, RADIO TURNING ON AND OFF AND HEATING AND COOLING TURNING ON AND OFF AND BATTERY BEING DRAINED. DEALER REPLACED 2 BATTERIES. 2. STABILITRAK WARNING LIGHT WOULD INTERMITTENTLY COME ON AND SAY IT NEEDED SERVICED. 3. GAS GAUGE STARTED MALFUNCTIONING AFTER A FILL UP. NEEDLE WOULD FLUCTUATE AND EVENTUALLY REMAIN ON E. WAS TOLD BY DEALER IT WAS EITHER THE FUEL LEVEL SENSOR OR INSTRUMENT PANEL. 4. VEHICLE STARTED TO JERK FORWARD WHEN SITTING AT STOP LIGHT. JERKS ARE STRONG ENOUGH THAT YOU FEEL LIKE YOU WERE REAR ENDED. THEN STARTED NOTICING THE JERKS WHILE DRIVING AT HIGHWAY SPEED. 5. OIL GAUGE BEGAN FLUCTUATING FROM HIGH TO LOW. WAS AGAIN TOLD IT WAS A BAD INSTRUMENT PANEL .6. REAR AIR SUSPENSION BEGAN DEFLATING WHEN VEHICLE WOULD SIT FOR LONG PERIODS OF TIME. LOW ENOUGH THAT TIRES ALMOST TOUCH TOP OF WHEEL WELL. COMPRESSOR WOULD COME ON AND REAR END WOULD COME BACK UP TO NORMAL. NOW IT DEFLATES OVER SHORT PERIODS OF TIME AND TAKES A CONSIDERABLY LONGER AMOUNT OF TIME TO REINFLATE. I AM NOW NOTICING THAT IT IS DEFLATING SOME WHILE DRIVING. IF YOU HIT A BUMP YOU CAN FEEL THE TIRE HIT THE TOP OF WHEEL WELL. DEALER COULD NOT EXPLAIN THE JERKING. WAS TOLD THERE WAS PROBABLY AN ELECTRICAL PROBLEM CAUSING THINGS TO COME ON AND OFF. FUEL GAUGE IS BEING REPLACED FREE AS A DEFECTIVE PART. WAS TOLD REAR SUSPENSION WAS MOST LIKELY A DEAD COMPRESSOR AND TIRES COULD POSSIBLY RUB OR BLOW OUT IF SUSPENSION DEFLATES WHILE DRIVING. *TR
I HAVE LOOKED INTO THIS ISSUE AND THERE ARE 1,000'S OF PEOPLE WITH THE SAME ISSUE I HAVE. MY AIRBAGS GO LOW OVER NIGHT AND UNDER 32 DEGREES DON'T PUMP UP AT ALL. I WORK 26 MILES AWAY AND TRAVEL TO WORK RIDING ON MY FRAME. MY BODY IS JARRED AND MY TRUCK IS GETTING BEATEN BECAUSE THE AIR RIDE SYSTEM IS NOT WORKING PROPERLY. YOU CAN HEAR THE PUMP WORKING AND I'VE BEEN TOLD THAT IT'S A VALVE NEEDED TO BE REPLACED. THIS ISSUE IS NOT FROM AGE. OTHERS HAVE HAD THIS PROBLEM AS EARLY AS 40K. *TR
I PURCHASED MY 2006 ENVOY BRAND NEW IN 2006 FROM WYATT JOHNSON IN CLARKSVILLE TN . THE REAR AIR SUSPENSION BAGS GAVE OUT IN 2010, THE VEHICLE WAS STILL UNDER WARRANTY SO I TOOK MY SUV TO GET REPAIRED AT WYATT JOHNSON, I ONLY PAID THE DEDUCTIBLE OF $150. IN JAN OF 2012 I NOTICED THAT THE REAR END OF THE VEHICLE WAS TAKING A LONG TIME TO AIR UP AND I ASSUMED THE SAME PROBLEM THAT OCCURRED IN 2010 WAS OCCURRING AGAIN. ON OCT 2012 I TOOK MY SUV TO GREINER BUICK GMC DEALERSHIP IN VICTORVILLE, CA AND WAS TOLD THE REAR AIR SHOCK HAD WENT OUT AGAIN AND THE REPAIRS WOULD COST ABOUT 1600, THE DEALERSHIP IS WILLING TO PAY THE COST AND I WILL HAVE TO COME OUT OF POCKET $785. I CALLED GM MOTORS BECAUSE THE MECHANIC TOLD ME THAT EVEN AFTER I GET IT REPAIR THIS IS AN ITEM THAT I WILL HAVE TO KEEP AN EYE ON AS LONG AS I HAVE THE SUV. WHEN I WAS SOLD THE VEHICLE THE SALES MAN SPOKE VERY HIGHLY OF THE AIR LIFT AND I WAS NEVER AWARE OF THE PROBLEMS AND HEAD ACHE THAT COULD OCCUR FROM HAVING A VEHICLE WITH THIS FEATURE. I FEEL IT'S A SAFETY HAZARD AND I FEEL AS THOUGH PAYING FOR IT TO GET REPAIRED IS NOT THE ANSWER I NEED TO BE ABLE TO EXCHANGE THIS VEHICLE FOR ONE THAT WILL NOT HAVE THE SAME RECURRING PROBLEM AGAIN. *TR
TL* THE CONTACT OWNS A 2006 GMC ENVOY DENALI. THE CONTACT STATED THAT THE VEHICLE WAS EQUIPPED WITH AN AIR SHOCK SYSTEM. WHILE DRIVING AT ANY SPEED, ALL OF THE AIR WOULD ESCAPE FROM THE SHOCK SYSTEM AND THE VEHICLE WOULD DROP DOWNWARD. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THE CONTACT WAS INFORMED THAT THERE WAS A LEAK WITHIN THE AIR SHOCK SYSTEM. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 64,000.
2006 ENVOY DENALI. CONSUMER WRITES STATES GAS NEEDLE STOPPED FUNCTIONING *TGW THE CONSUMER STATED THE GAS NEEDLE BEGAN TO FLUCTUATE IN THE BEGINNING AND SINCE THAT TIME, THE NEEDLE HAS BEEN STUCK ON EMPTY, AND THE ENGINE LIGHT ILLUMINATED AS A RESULT. IN MARCH OF 2009, WHEN THE CONSUMER STARED THE VEHICLE, IT SOUNDED AS IF THERE WAS SOMETHING METAL TUMBLING AROUND UNDER THE HOOD. UPON INSPECTION OF THE VEHICLE, IT WAS DETERMINED THE ENGINE NEEDED TO BE REPLACED. ON JUNE 10, 2010, THE VEHICLE WOULD NOT START AND HAD TO BE TOWED TO THE DEALER. AN INSPECTION REVEALED A STARTER WAS NEEDED. ALSO, AN ALIGNMENT WAS DONE AND THE REAR BRAKE LIGHT WAS REPLACED. ON JUNE 12, 2010, THE VEHICLE WOULD NOT COME OUT OF PARK. AFTER 25 MINUTES AND OVER 50 ATTEMPTS, IT FINALLY CAME OUT OF PARK. THE CONSUMER DROVE TO THE DEALER, BUT THEY WERE UNABLE TO FIND A PROBLEM. SEPTEMBER 2010, THE CONSUMER NOTICED THE REAR OF THE TRUCK WAS SITTING VERY LOW. THE REAR END AIR SUSPENSION NEEDED TO BE REPLACED. THE AIR CONDITION RANDOMLY WORKED. THERE WERE TIMES WHERE THE AIR WOULD JUST START BLOWING AND NO BUTTONS WERE PUSHED. ALSO, THE DEFROSTER STOPPED WORKING. THE CONSUMER CONTINUED TO EXPERIENCE PROBLEMS WITH THE VEHICLE NOT COMING OUT OF PARK. *JB
REAR AIR SHOCKS THAT BLED DOWN AFTER SITTING FOR EXTENDED PERIODS OF TIME. TOOK TO DEALER FOR EVALUATION AND WAS INFORMED THAT THE AIR SHOCKS NEEDED REPLACEMENT. WAS ALSO INFORMED THAT NORMALLY THE AIR COMPRESSOR IS REPLACED ALSO BECAUSE IT IS THE CAUSE OF THE LEAKING. I DECIDED COST WAS TOO GREAT SO I CHOSE TO ADD SPRINGS IN PLACE OF REAR AIR SHOCKS AND WAS INFORMED THAT THE AIR COMPRESSOR WOULD CONTINUE TO FUNCTION. NOW THE AIR COMPRESSOR DOES NOT WORK, TOOK BACK TO DEALER TO FIND OUT WHAT THE PROBLEM IS AND WAS INFORMED THAT ONCE THE REAR AIR SHOCKS ARE REMOVED THE AIR COMPRESSOR IS DISABLED. *KB
