2009 GMC Yukon Hybrid

WHILE DRIVING ON THE HIGHWAY BETWEEN 65-70 MILES AN HOUR MY VEHICLES CHECK ENGINE LIGHT CAME ON AND LA MESSAGE OF ENGINE POWER REDUCED APPEARED. THE VEHICLE LOSS POWER BUT I WAS ABLE TO MAKE IT TO THE SHOULDER SAFELY. THE CAR WOULD NOT TURN ON AND I HAD TO CAL AAA TO TAKE MY CARE TO THE DEALER. THE DEALER SAID THAT THE VALVE BODY INTERNALLY SHORTED THE MEMORY CIRCUIT AND THE CRANKSHAFT SENSOR SHORTED. THE DEALER SAID THAT THEY FOUND THE HARNESS FOR THE CRANKSHAFT HAD MELTED AND SHORTED OUT THE SENSORS. THEY REPAIRED THE HARNESS, REPLACED THE SHORTED OUT SENSOR AND REPLACED THE VALVEBODY/TCM. DO NOT KNOW WHAT CAUSED THE VALVE BODY TO SHORT AND CAUSE THE CRANKSHAFT SENSOR TO MELT. *TR

IN LATE MAY 2014 I STARTED GETTING A BRAKE ERROR MESSAGE & MY BRAKES WOULD NOT WORK PROPERLY. I WOULD PUSH DOWN ON THE BRAKES & IT WOULD BE HARD TO BRAKE. I WAS BARELY ABLE TO PULL OVER, HOWEVER I MADE IT TO THE SIDE OF THE HIGHWAY & TURNED OFF MY VEHICLE, WHEN I TURNED IT ON THE BRAKE ERROR WAS GONE & MY BRAKES SEEMED TO WORK. I TOOK MY CAR TO THE DEALER ON MAY 29, 2014 THEY SAID IT WAS THE MASTER BRAKE CYLINDER SENSOR, BUT I HAD TO WAIT BECAUSE GM HAD THE ITEM ON BACK ORDER. I GOT THE CAR REPAIRED BUT THE DAY AFTER I PICKED IT UP THE SAME THING HAPPENED BUT THIS TIME MY BRAKES FAILED COMPLETELY & WE HAD TO USE THE EMERGENCY BRAKES AND ALMOST GOT INTO AN ACCIDENT DUE TO THE FAILURE. I TOOK THE CAR IN AGAIN & THEY SAID THEY NEEDED TO REPAIR THE ABS BRAKE ASSEMBLY, SO WE PROCEEDED TO APPROVE THE REPAIR & GET THAT FIXED. I PICKED UP THE CAR AFTER THIS 2ND REPAIR FOR THE SAME ISSUE,BUT WHEN I WAS DRIVING OFF THE LOT I AGAIN GOT THE SAME BRAKE ERROR MESSAGE & MY BRAKES AGAIN WERE FAILING. I DID A U TURN BACK INTO THE DEALER. MY CAR HAS BEEN THEE EVER SINCE. THIS TIME AROUND THEY SAID I NEEDED A COUPLE MORE PARTS ONE BEING AN ADAPTER GM # 25862232. HOWEVER, THIS ADAPTER IS NOT AVAILABLE ANYWHERE IN THE USA OR ABROAD. I CONTACTED GM & THEY SAID THEY KNOW MY CARS REPAIR ISSUES BUT DO NOT HAVE THE PART AND DON'T KNOW WHEN THEY WILL HAVE IT. *TR
