ELECTRICAL SYSTEM
VEHICLE RANDOMLY GOES INTO REDUCE ENGINE POWER MODE AND STALLS WHILE DRIVING. THIS HAS HAPPENED MULTIPLE TIMES WHILE DRIVING ON A HIGHWAY AND GOING UP A HILL WHERE IT NEARLY CAUSED A THREE CATASTROPHIC ACCIDENTS. BASIC RESEARCH SHOWS THAT GM HAS KNOWN ABOUT THIS ISSUE SINCE THE VEHICLES WERE A FEW YEARS OLD AND IT AFFECTS MANY YEARS OF GM VEHICLES. THERE IS A PROBLEM WITH BAD GROUNDING CONNECTORS RELATED TO THE THROTTLE BODY SENSOR AND AND WIRING HARNESS.

ELECTRICAL SYSTEM
INSTRUMENT CLUSTER. GAUGES RANDOMLY STICK OR FALSELY READ TO INCLUDE SPEEDOMETER. SOMETIMES IT WILL STICK AT A RANDOM SPEED. OTHER TIMES IT WILL PEG AT ITS MAX. UNKNOWN IF ODOMETER IS INVOLVED. SOMETIMES THEY RESET AFTER REPEATED START/OFF CYCLES. WAS COVERED UNDER A GM RECALL BULLETIN NO: 07187B, PAGE 8. CURRENT ODOMETER IS 145,369. SHOULD GM NOT REPAIR THIS AFTER THE WARRANTED PERIOD? THIS IS JUST AS DANGEROUS NOW THAN IT WAS AT 70,000 MILES. OIL PRESSURE GAUGE VERY RARELY READS CORRECTLY. I TRAILER TOW OFTEN AND CORRECT OIL PRESSURE IS IMPERATIVE AS IS A CORRECT SPEEDOMETER READING. ON THE TOP OF THE PAGE I DOWNLOADED FROM NHTSA IS THE NUMBER CSC-10026542-8984. PLEASE NOTE THAT THIS BEGAN TWO YEARS AGO WITH A FAULTY AMP GAUGE BUT WITHIN THE LAST SEVERAL MONTHS IT HAS NOW AFFECTED ALL GAUGES BUT THE FUEL GAUGE, WATER TEMP AND TRANSMISSION TEMP. POSSIBLY RELATED IS THE HEATED SEAT ON THE DRIVERS SIDE. THE HEAT IS ON ALL THE TIME (ON HI) AND CAN ONLY BE SHUT OFF BY UNPLUGGING THE SEAT WHICH DEACTIVATES THE AIR BAG SENSOR, POWER SEAT CONTROL AND THE LIKE. I HAVE NOT CONTACTED GM AT THIS TIME. PLEASE ADVISE ME AS TO MY COURSE OF ACTION.

SERVICE BRAKES
THE BRAKES FAILED WHILE DRIVING ON A CITY STREET CAUSING MY VEHICLE TO NEARLY STRIKE A NUMBER OF CHILDREN AT A CROSSWALK. AFTER EXAMINATION BY A MECHANIC, IT WAS DETERMINED THAT THE BRAKE LINE HAD CORRODED AND BURST UNDER PRESSURE. I HAVE RECEIVED NO NOTICE OF THIS POTENTIAL FAILURE FROM GMC EVEN THOUGH IT HAS BEEN INVESTIGATED BY THE NHTSA. SHOULDN'T THE MANUFACTURER HAVE AN OBLIGATION TO REPAIR THIS POTENTIALLY LETHAL PROBLEM? AT A MINIMUM I FEEL THAT GMC AND/OR THE NHTSA HAVE A MORAL OBLIGATION TO NOTIFY OWNERS OF AFFECTED VEHICLES THAT THEY ARE DRIVING A POTENTIALLY DEADLY VEHICLE.

SERVICE BRAKES, STEERING, ELECTRICAL SYSTEM
WHILE TRAVELING TO WORK MY VEHICLES CHECK ENGINE LIGHT CAME ON AND THE REDUCED POWER WARNING CAME ON AT WHICH TIME I HAD COMPLETE LOSS OF ACCELERATION, COMPLETE LOSS OF BRAKING, AND COMPLETE LOSS OF STEERING POWER. I THEN HAD TO COAST TO A STOP AND ATTEMPTED TO RESTART THE VEHICLE 6 TIMES BEFORE I WAS ABLE TO GET THE REDUCED POWER WARNING TO GO OFF AND WAS ABLE TO DRIVE ALTHOUGH THE CHECK ENGINE LIGHT STAYED ON. THIS IS THE 2ND TIME THIS HAS HAPPENED TO ME IN 2 DAYS WITH THE LOSS OF POWER. I HAVE HAD THE REDUCED POWER WARNING ON NUMEROUS OCCASIONS YEARS PAST BUT NEVER HAVE I LOST TOTAL / ABSOLUTE POWER TO CONTROL THE VEHICLE, THIS IS A TOTAL DEATH TRAP FOR ANYONE WHO HAS HAD THIS EXPERIENCE, ESPECIALLY ON THE FREEWAY OR HIGHWAYS AT HIGH SPEEDS. I HAVE READ NUMEROUS ACCOUNTS OF THIS SAME ISSUE AFFECTING OTHER GMC OWNERS AND HAVE SEEN NO RESOLUTIONS OR ANY RECALLS FROM GMC. I HAVE ALREADY REPLACED THE THROTTLE HOUSING AND HARNESS COMPONENTS, ACCELERATION PEDAL SENSOR AND YET THE ISSUE CONTINUES, SOMEONE IS GOING TO ( DIE ) BECAUSE OF GMC'S LACK OF CONCERN AND RESPONSIBILITY TO OWNERS OF THEIR PRODUCTS. I WILL NEVER EVER OWN ANOTHER GMC ASSOCIATED PRODUCT.

VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM, POWER TRAIN
THERE IS AN ERROR MESSAGE THAT DISPLAYS ON THE DASH FOR MYSELF AND THOUSANDS OF OTHERS WHO OWN GMC/CHEVY TRUCKS WITH THESE MOTORS. THEY HAVE A DEFECTIVE THROTTLE POSITION SENSOR WITH THE TRUCK WHERE IT SAYS "REDUCED ENGINE POWER". I'VE FOUND 2 TECHNICAL SERVICE BULLETINS THAT SOMEWHAT ADDRESS THE ISSUE, BUT MANY PEOPLE TAKE THEIR TRUCKS TO MECHANICS AND DEALERSHIPS TO GET THE ISSUE FIXED AND SPEND THOUSANDS OF DOLLARS IN REPAIRS AND TROUBLESHOOTING TO GET THE ISSUE RESOLVED, TO NO AVAIL. THE 2 TECHNICAL SERVICE BULLETINS THAT I FOUND WERE #PIP3089B (DATED 10/31/2006) AND #PIP3042A (DATED 8/30/2004). I'VE SEEN ON MANY MANY FORUM POSTS ABOUT THIS ISSUE AND POSSIBLE FIXES, WHICH WHEN I READ DEEPER INTO THEM, SEEM TO NOT BE TRUE FIXES.

ENGINE, VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
I KEEP HAVING THE DISPLAY SAY "REDUCED ENGINE POWER". I'LL BE DRIVING ON THE HIGHWAY, DOING 65 IN RUSH HOUR TRAFFIC, WHEN ALL OF THE SUDDEN THE ACCELERATOR NO LONGER ACCELERATES AND IT DISPLAYS "REDUCED ENGINE POWER" ON THE GAUGE CLUSTER DISPLAY. FROM WHAT I'VE SEEN ONLINE IT APPEARS TO BE AN ISSUE WITH THE THROTTLE POSITION SENSOR ON THOUSANDS OF OTHER SIMILAR VEHICLES WITH THE SAME ENGINE, CHEVY SUBURBAN'S, SILVERADO'S, TAHOE'S, ETC. I REPLACED THE THROTTLE POSITION SENSOR AND THE HARNESS (BECAUSE I HEARD THE HARNESS MIGHT ALSO BE AN ISSUE) AND I AM STILL HAVING THE SAME PROBLEM WITH MY TRUCK. IT HAS DONE IT OVER A DOZEN TIMES ON ONE TRIP BACK FROM WORK (80 MILES FOR ME). I HAVE TO PULL OVER TO THE SIDE OF THE ROAD (IF POSSIBLE) AND TURN OFF THE TRUCK, THEN WAIT A SHORT PERIOD OF TIME, THEN TURN THE TRUCK BACK ON. THIS USUALLY FIXES THE ISSUE, BUT IT DID NOT HELP ME WHEN IT HAPPENED TO ME IN THE TUNNEL AND I WAS GOING 5 MPH (TOP SPEED DURING THE "REDUCED ENGINE POWER" MODE, ONCE YOUR DRIFTING STOPS (BECAUSE YOU DRIFT, IT DOESN'T ENGAGE THE BRAKES). I WAS EXTREMELY WORRIED THAT I WOULDN'T MAKE IT OUT OF THE TUNNEL WITHOUT GET REAR ENDED, AND ONCE I MADE IT OUT, I WAS JUST OUTSIDE OF THE TUNNEL AWAITING ROADSIDE ASSISTANCE, IT WAS VERY FRIGHTENING, WITH MY DAUGHTER IN THE CAR.

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
WHILE SITTING IDLE MY VEHICLE SUDDENLY WENT INTO REDUCED ENGINE POWER MODE. I WAS ABLE TO GET OVER AND PULL OFF THE ROAD AND SHUT OFF THE CAR. 5 MINUTES LATER THE CAR STARTED LIKE THERE WAS NO PROBLEM. OVER THE NEXT FEW DAYS THE REP WARNING WOULD SHOW UP AND MY CAR WOULD SUDDENLY LOSE POWER. I WAS CROSSING THE ROAD DURING ONE INCIDENT. HOWEVER, WHEN I WOULD SHUT OFF THE CAR AND RESTART THE CHECK ENGINE LIGHT WOULD GO AWAY AS WOULD THE REP WARNING. AFTER A QUICK REVIEW ONLINE IT IS EASY TO FIND HUNDREDS OF PEOPLE WHO HAVE A SIMILAR ISSUE. GM WILL ONLY DIAGNOSE AND IF THE LIGHT IS OFF WHEN YOU GET THERE THERE IS NOTHING FOR THEM TO DO EXCEPT TAKE YOUR MONEY AND SAY GOOD LUCK.
