WHILE DRIVING ON A CITY STREET AT APPROXIMATELY 40 MPH THE VEHICLE STARTED MAKING A LOUD NOISE (SIMILAR TO THE SOUND A DIRT BIKE ENGINE MAKES). THE SOUND BECAME LOLUDER WHEN I PRESSED THE BRAKES. I TOOK THE VEHICLE TO THE REPAIR SHOP AND WAS NOTIFIED THAT THE HYDROBOOSTER FAILED RESULTING IN A STEERING FLUID LEAKAGE.

THEY DID A SMOKE TEST AND FOUND OUT THE FUEL PUMP UNIT WAS ALL RUSTED OUT AND ALSO THE STRAPS HOLDING THE FUEL TANK IN WAS ALL RUSTED OUT.

Owner report 10482642 · 2012-10-30 (October 30, 2012)
AT FIRST THE WASHERS JUST KEPT SPRAYING AND WOULDN'T STOP. I HAD TO TAKE OUT THE FUSE TO GET IT TO STOP. I RECENTLY PUT THE FUSE BACK IN AND NOW IT WON'T WORK. THE WASHERS WILL JUST START SPRAYING OUT OF THE BLUE AND THIS IS VERY DANGEROUS IF YOU ARE DRIVING DOWN THE ROAD AND YOU CAN'T GET IT TO STOP. IT DECREASES YOUR VISIBILITY. I HAVE READ THAT THEY HAVE HAD RECALLS ON THIS ISSUE. IT SOUNDS LIKE THEY HAVE ALOT OF ELECTRICAL ISSUES. ALSO THE HEATING UNIT ON MY DRIVER SEAT RANDOMLY COMES ON BY ITSELF AND WON'T SHUT OFF. I BOUGHT THIS HUMMER US…
