2004 GMC Yukon

TL* THE CONTACT OWNS A 2004 GMC YUKON. WHILE MOVING FROM THE PARK POSITION, THE BRAKE SYSTEM DISABLE WARNING INDICATOR ILLUMINATED. THE BRAKE PEDAL WAS DEPRESSED, BUT FAILED TO OPERATE. THE EMERGENCY BRAKES ALSO FAILED TO OPERATE. THE CONTACT STATED THAT THERE WAS BRAKE FLUID EVIDENT UNDER THE FRONT OF THE VEHICLE. THE CONTACT ALSO STATED THAT THE BRAKE LINE WAS EXTREMELY CORRODED. THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 04V045000 (SERVICE BRAKES, HYDRAULIC). THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 152,000.

TL* THE CONTACT OWNS A 2004 GMC YUKON. WHILE THE VEHICLE WAS STATIONARY, WATER ENTERED THE HVAC SYSTEM AND CAUSED THE BLOWER RESISTER MODULE TO CORRODE. AS A RESULT, THE WIRING HARNESS HEATED UP, WHICH COULD HAVE POTENTIALLY CAUSED A FIRE IN THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS 145,000.

WHILE DRIVING DOWN ROAD AT APPROXIMATELY 45 MPH, HIT THE BRAKES WHEN A COUPLE OF DEER JUMPED ONTO ROAD AND THE PEDAL WENT TO FLOOR WITH NO BRAKING ACTION AT ALL. HAD ENOUGH TIME TO REALIZE WHAT HAD HAPPENED AND HIT THE PARKING BRAKE IN TIME BEFORE REACHING INTERSECTION TO BUSY HIGHWAY. INSPECTION AFTERWARD SHOWED BRAKE FLUID ON THE FRAME NEAR THE DRIVER SIDE DOOR WHERE THE PROPORTIONING VALVE IS LOCATED. THERE WAS NO WARNING OF THE FAILURE AND HAD BEEN DRIVING THE VEHICLE AROUND TOWN MOST OF THE DAY. HAVE EXPERIENCED BRAKE FAILURES ON VEHICLES BEFORE AND ALWAYS HAD HALF THE SYSTEM REMAIN OPERATIONAL ENOUGH TO STOP WITHOUT PROBLEM. THIS APPEARS TO HAVE BEEN A SINGLE FAILURE MODE THAT CAUSED THE LOSS OF BRAKING OR A SIMULTANEOUS FAILURE OF MULTIPLE SYSTEMS WHICH SHOULD BE UNLIKELY BUT SEEMS TO HAPPEN WITH IMPROBABLE REGULARITY BASED ON COMPLAINTS POSTED.

ENGINE LOSING COOLANT, WITH NO APPARENT SIGNS OF LEAKAGE. COOLANT APPEARS TO BE LEAKING INTO THE ENGINE OIL, CAUSING IT TO SLUDGE, THEREBY CAUSING ENGINE FAILURE. GM IS AWARE OF AN ISSUE AND ISSUED TSB 06-06-01-019B FOR DEFECTIVE CYLINDER HEAD CASTING. I BOUGHT THIS CAR USED LAST YEAR AND NOW OWE 10000 FOR A CAR THAT NEEDS A 6000 ENGINE REPLACEMENT. GM SHOULD BE MADE ACCOUNTABLE FOR THIS SINCE THEY ARE WELL AWARE OF THE ISSUE, PER THEIR OWN DIRECTIVE.

SURGE HAPPENS WHILE DRIVING, THEN ENGINE LIGHT COMES ON, DECREASED ENGINE POWER OCCURS, TRACKTION STABILITY INDICTORS COMES ON. CAR LOOSES POWER. I HAVE TO PULL OVER OFF THE ROAD, PUT INTO PARK,CUT IGNITTION OFF, WAIT A FEW MINUTES AND THEN RESTART THE CAR. THIS COULD HAPPEN SEVERAL TIMES WHILE DRIVING.THE VEHICLE IS IN MOTION AND THIS IS A DRIVING HAZARD AND BIG SAFETY ISSUE, IT HAS HAPPENED ON CITY STREET AND ON A HIGHWAY. IT HAPPENS DAILY.

WHILE DRIVING DOWN AN ON RAMP I BEGAN TO APPLY THE BRAKES TO SLOW DOWN, THE BRAKE PEDAL SUNK TO THE FLOOR AND I HAD NO BRAKING CAPABILITY AND THE BRAKE WARNING APPEARED ON THE DASH. I PUMPED THE BRAKE AGAIN AND STILL HAD NO BRAKING CAPABILITY, I WAS ABLE TO COAST TO A STOP ALONG THE SIDE OF THE ROAD. UPON INSPECTION OF THE BRAKE LINES, THERE WAS A MAJOR LEAK ON THE REAR DRIVER SIDE, AND A SMALLER LEAK FROM ON THE FRONT PASSENGER SIDE.

THE GAUGES IN THE INSTRUMENT CLUSTER STOP WORKING. FIRST THE SPEEDOMETER THEN THE TACHOMETER, AND NOW THE AMP METER. ON GOING PROBLEM. DEFINATELY A SAFETY CONCERN BUT NO ONE WANTS TO ADDRESS THE ISSUE. THE DEALER WANTS 600.00 DOLLARS TO REPAIR IR BUT DOES NOT GUARANTEE IT WILL BE THE FIX. OTHER VEHICALS OF THIS YEAR AND MODEL HAVE THE SAME ISSUE.
