NHTSA Complaint #10548180 — 2006 GMC ENVOY DENALI

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
