2006 GMC Yukon Speed Control & Cruise Problems

MY VEHICLE WAS IN MOTION DRIVING ON THE FREEWAY AT 70 MPH WHEN ALL OF THE SUDDEN MY CAR LOST POWER TO 30 MPH ALL THE WAY DOWN TO 5 MPH.I PRESSED ON THE ACCELERATOR TRYING TO GAIN SPEED WITHOUT SUCCESS THE CAR DID NOT ACCELERATE MORE THAN 30 MPH, NO MATTER HOW MUCH I PRESSED ON THE ACCELERATOR. WHEN I LOOKED DOWN AT THE DASHBOARD I SAW TWO WARNING LIGHTS GO OFF "STABILITY SYS DISABLED" FOLLOWED BY "REDUCED ENGINE POWER" LUCKILY I WAS ABLE TO MOVE TO SAFETY. THE ROAD WAS DRY AND NO BUMPS TO DISABLE STABILITY. THE TRACTION CONTROL IN THIS VEHICLE IS LOCATED FAR FROM MY STEERING WHEEL SO I KNOW I DID NOT ACCIDENTLY HIT THE TRACTION CONTROL BY ACCIDENT. AFTER I WAS ABLE TO PULL OVER I WAS ADVISED TO HIT THE TRACTION CONTROL BUTTON TO SEE IF THAT WOULD FIX THE ERROR IN THE DASH. THAT DID NOT WORK. I IMMEDIATELY TOOK IT TO THE DEALER CONCERN FOR MY SAFETY AND THAT OF MY FAMILY. THE DEALER HAS HAD MY FOR SEVERAL DAYS RETURNED MY CAR BACK ONCE STATING THAT IT WAS DUE TO MASTER AIR FLOW SENSOR ALONG WITH THE AIR FILTER ONCE THOSE PARTS WERE REPLACED I PICKED UP MY CAR AS SOON AS I PICKED UP THE CAR AND DROVE IT AROUND THE CORNER I EXPERIENCED THE SAME ISSUE. I DROVE IT BACK TO THE DEALER AT 5 MPH AS I WAS NOT ABLE TO GO ANY FASTER NO MATER HOW MUCH I PRESSED ON THE ACCELERATOR. 2ND TIME THE CAR WAS RETURNED TO ME I WAS TOLD IT WAS JUST THE BUTTERFLY IN THE THROTTLE BODY AND THAT IT WAS REPLACED FOR A NEW ONE. I WAS DRIVING AWAY AND GOT JUST A LITTLE FARTHER THAN THE FIRST TIME WHEN I GOT THE SAME ERROR MESSAGE AGAIN I DROVE IT BACK TO THE DEALER AND THEY TOLD ME IT WAS A FAULTY THROTTLE BODY THEY REPLACED THAT BUT ITS STILL HAVING ISSUES. I BELIEVE THIS TO BE A SAFETY HAZARD WHILE DRIVING I WANT THIS NOTED IN CASE THERE IS A MAJOR ACCIDENT WITH FATALITIES.

WHILE DRIVING MY SUV ON THE FREEWAY, THE ABS ,TRACTION CONTROLL,BRAKE LITE ON THE INSTRUMENT CLUSTER STARTED FLASHING AND CHIMING. SERVICE STABILITY WAS FLASHING ON THE DIC. THE DEALER SAID THE ABS MODULE NEEDS TO BE REPLACED. THERE IS A LOSS OF HVAC CONTROLL ,NO AC AND VENTILLATION OR HEATING,LOSS OF CRUISE CONTROL. PLEASE ADVICE.

INTERMITTENTLY, WHEN MY 2006 GMC YUKON DENALI XL IS AT A STOP LIGHT OR SIGN AND I AM DRIVING LESS THAN 10MPH AND I GO TO ACCELERATE (NOT SPINNING THE TIRES AND NOT ON WET OR SLIPPERY SURFACES) THE "TRACTION ACTIVE" MESSAGE DISPLAYS AND I LOSE ALL POWER FOR A COUPLE OF SECONDS. THIS MANY TIMES HAS LEFT ME IN THE MIDDLE OF AN INTERSECTION WITH ON-COMING TRAFFIC. I HAVE GOOGLED THIS TRACTION ACTIVE AND THERE ARE MANY ARTICLES FROM OTHER YUKON OWNERS STATING THEY HAVE THE EXACT SAME ISSUE THAT I AM HAVING. I PRINTED OFF 9 PAGES AND TOOK TO MY DEALER/SERVICE DEPARTMENT (SIMMONS ROCKWELL IN BATH, NY) AND AFTER LOOKING AT THE VEHICLE, THEY SAID THERE WAS NOTHING WRONG WITH IT. I EVEN SUPPLIED THEM WITH AN ABS RECALL DOCUMENT ID # 1819672 OF WHICH THE SUBJECT IS 'PRODUCT SAFETY ' FRONT WHEEL SPEED SENSOR CORROSION #05068B. THESE VEHICLES MAY HAVE A CONDITION PERMITTING CORROSION TO OCCUR BETWEEN THE FRONT HUB/BEARING ASSEMBLY AND THE WHEEL SPEED SENSOR. IF THE BRAKES ARE APPLIED WHILE THE VEHICLE IS TRAVELING AT A SPEED OF GREATER THAN 3.7 MPH BUT LESS THAN 10 MPH, THE CORROSION MAY CAUSE AN UNWANTED ANTI-LOCK BRAKE SYSTEM ACTIVATION. IF THIS CONDITION OCCURRED WHERE STOPPING DISTANCE IS LIMITED, A CRASH COULD OCCUR.' MY DEALER SAID THE COMPUTER DIDN'T SHOW ANY ISSUES, BUT AS SOON AS I DROVE HOME IT HAPPENED AGAIN. I DON'T THINK MY DEALER EVEN LOOKED AT THE DOCUMENTS I PROVIDED TO THEM TO HELP THEM DIAGNOSE THE ISSUE. THIS IS A MAJOR SAFETY CONCERN AND I WONDER HOW MANY OTHER PEOPLE WITH GMC YUKONS ARE HAVING THE SAME ISSUE AND HAVE JUST NOT DONE ANYTHING ABOUT IT. *TR

PERIODIC "TRACTION ACTIVE" INDICATOR LIGHT ALONG WITH GAS PEDAL INOPERABLE. BECAME MORE FREQUENT AND DURING LONG ROAD TRIP FOR WORK, ALMOST GOT INTO 3 ACCIDENTS. ONLY OCCURS WHEN STARTING OUT OR DURING ACCELERATION WHILE GOING SLOW. TWICE AT STOP SIGN WHILE CROSSING BUSY INTERSECTIONS, VEHICLE DIED IN MIDDLE OF INTERSECTION WHEN PULLING OUT FOR SEVERAL SECONDS. CAUSED TRAFFIC TO STOP AND ALMOST HAD COLLISION. ONCE HAPPENED WHILE MAKING LEFT TURN AT INTERSECTION. SAME RESULTS. SAW MANY SIMILAR COMPLAINTS ON FORUMS ABOUT GMC YUKON. USUALLY HAPPENS AFTER 40K (WARRANTY EXPIRED) I JUST WENT OVER 40K LAST WEEK. SEEMS LIKE PROBLEM STARTED BACK IN 2003 VERSION, FROM ALL OTHER COMPLAINTS I READ ABOUT. REPAIR: DEALER FOUND INCORRECT READINGS FROM RIGHT FRONT WHEEL SPEED SENSOR, SENSOR ONLY AVAILABLE AS PART OF RF HUB ASSY. PN 015233113 $377.36 ($600+ INSTALLED) I EXPLAINED ALL OTHER COMPLAINING ABOUT SAME PROBLEM AND HOW THIS IS A VERY BIG SAFETY ISSUE. DEALER SAID THEY CAN DO NOTHING. *TR

WHILE ACCELERATING FROM A COMPLETE STOP THE VEHICLE GOES INTO TRACTION CONTROL FOR NO REASON STALLING IN THE MIDDLE OF THE INTERSECTION. THE DISPLAY FLASHES TRACTION ACTIVE EVEN THOUGH THE PAVEMENT IS DRY AND FREE OF LOOSE DEBRIS. YOU HAVE TO LET THE ACCELERATOR GO AND RE-ACCELERATE TO DEACTIVATE THE TRACTION CONTROL, LEAVING YOU STALLED IN THE MIDDLE OF THE INTERSECTION. GM HAD A RECALL FOR LARGE SUVS AND PICK-UPS WITH A VERY SIMILAR PROBLEM, THE ONLY DIFFERENCE WAS THE DISPLAY FLASHED AN ABS FAULT BUT THE REPAIR FOR THAT RECALL WAS EXACTLY THE SAME AS FOR THE TRACTION ACTIVE FAULT. ABS IS PART OF THE TRACTION CONTROL SYSTEM, SO JUST BECAUSE GM FOUND A WAY TO THROW A DIFFERENT CODE FOR THE EXACT SAME PROBLEM THEY'RE NOT OBLIGATED TO TAKE CARE OF THIS POTENTIALLY VERY DANGEROUS PROBLEM THAT LEAVES YOU IN NO CONTROL OF YOUR VEHICLE IN THE MIDDLE OF AN INTERSECTION WHILE MOVING FROM A STOP LIGHT OR STOP SIGN. PLEASE LOOK INTO THIS BEFORE SOMEBODY GETS HURT OR DEAD FROM GETTING T-BONED BECAUSE THEY CAN'T GET OUT THE WAY. *TR
