STABILITRAK OFF/REDUCED ENGINE POWER CAME ON AGAIN AFTER 3 UNSUCCESSFUL 'FIXES' AT GMC DEALER. I WAS DRIVING 30MPH OVER A HILL WHEN MY ENGINE COMPLETELY STOPPED RESPONDING. COULDN'T ACCELERATE AND THE STEERING WHEEL LOCKED. WENT INTO ONCOMING LANE BUT FORTUNATELY I WASN'T HIT. I WAS ABLE TO PULL TRUCK TO SHOULDER AND WAIT A FEW MINUTES BEFORE BEING ABLE TO TURN ON AGAIN AND GET IT HOME. I HAVE TAKEN THE TRUCK TO MY LOCAL DEALER EVERY TIME THIS HAS HAPPENED AND THEY ONLY REPLACE THE THROTTLE BODY SENSOR. IT'S THE SECOND TIME THE TRUCK HAS STOPPED RESPONDING WHILE DRIVING. THE FIRST TIME WAS ON A HIGHWAY 99 WHEN ALL LIGHTS CAME ON AND TRUCK STARTED SLOWING DOWN DUE TO LACK OF ENGINE POWER. I WAS LEFT STRANDED ONCE AND HAD TO GET TRUCK TOWED FOR A TOTAL OF $430. I'M FEELING UNSAFE IN MY VEHICLE AND GM HAS IGNORED MY CONCERNS ABOUT THIS ISSUE.

ISSUE #1-WHILE DRIVING THE VEHICLE STABLITRAK WARNING LIGHT, TRACTION CONTROL, ENGINE POWER REDUCED, AND BRAKE LIGHT ALL CAME ON. VEHICLES ENGINE POWER WAS SUDDENLY REDUCED TO ABOUT 10 MPH WHILE DRIVING ON THE INTERSTATE IN WHICH I FOUND TO BE VERY DANGEROUS! HAD TO PULL OVER, TURNED OFF VEHICLE, LIGHTS WENT OFF, STARTED DRIVING AGAIN, VEHICLE DID THE SAME THING. HAD TO TAKE IN FOR MECHANICAL REPAIRS. ISSUE #2- KEY IGNITION SWITCH JUST STARTED LOCKING UP ON THE VEHICLE, WOULD NOT TURN BACK TO NORMAL TO POSITION, HAD TO REPEATEDLY KEEP JIGGLING FOR OVER 30 MINUTES OR SO TO GET THE VEHICLE STARTED BACK UP?? HAD TO TAKE VEHICLE TO DEALER FOR REPAIRS ALSO. THESE ARE VERY UNSAFE AND COSTLY ISSUES THAT GMC SHOULD BE MANDATORILY REQUIRED TO HAVE RECALLED AND IMMEDIATELY ADDRESSED FOR THE SAFETY OF THE GENERAL PUBLIC!!

WHILE DRIVING ON HIGHWAY CHECK ENGINE LIGHT CAME ON AND LOST POWER. ALSO STARTED TO HEAR TAPPING COMING FROM ENGINE. HAD IT CHECKED BY MECHANIC. FOUND CODE P0306 CYLINDER 6 MISFIRE. CHECKED GM TRUCK WEB SITE AND NOTED SERVICE BULLETIN NOTING VALVE LIFTER FAILURE, BUT NO RECALL. BULLETIN STATES THAT LIFTER CAN FAIL CAUSING MISFIRE AND TAPING IN MOTOR. ALSO STATES DURING REPAIR TO CHECK CAM SHAFT FOR SCORING & DAMAGE. ALSO CHECKED SEVERAL GM & CHEVY CAR FORM WEBSITES, AND NOTED MULTIPLE COMPLAINTS ABOUT SAME ISSUES AS WELL AS SEVERAL NEAR ACCIDENTS BECAUSE OF LOSS OF POWER WHILE DRIVING. THERE ARE ALSO SEVERAL YOUTUBE VIDEOS OF ISSUES WITH THIS MOTOR AND VALVE LIFTER FAILURE. THIS HAPPENS BECAUSE CYLINDERS SHUT DOWN DURING CRUISING. LIFTERS THAT FAIL HAVE A SPRING ATTACHED THAT FAILS CAUSING THE MISFIRE AND SCORING TO CAM SHAFT. GM IS AWARE OF ISSUE BUT FAILS TO ISSUES A RECALL FOR REPAIRS TO THIS MOTOR. THIS IS A HAZARD AND COULD CAUSE AN ACCIDENT. REPAIRS SHOULD ALSO BE COVERED BY GM AS THIS IS A COMMON PROBLEM WITH THIS MOTOR AND THEY ARE AWARE OF IT WITH THEIR IN HOUSE SERVICE BULLETIN TO SERVICE MANAGERS. THIS ISSUES CAN HAPPEN AND BE COVERED BY SERVICE WARRANTY, BUT NOT COVERED WHEN OUT OF WARRANTY. BULLETIN ALSO GOES ON TO STATE HOW TO WRITE IT UP IF COVERED BY POWERTRAIN WARRANTY.

SOMETHING IS WRONG WITH THE ELECTRICAL SYSTEM. ALL MY DOOR LOCKS REPEATEDLY LOCK AND UNLOCK, ALL MY EMERGENCY CHECKS AND SERVICE LIGHT GO ON AND OFF, MY GAUGES ALL DROP TO ZERO, AND MOST RECENTLY MY VEHICLE HAS SHUT DOWN WHILE I'M DRIVING IT. BUT IT HAPPENS RANDOMLY. SOMETIMES IT'S WORSE THAN OTHERS. I RECENTLY HAD TO STEER UP ONTO A CURB BECAUSE I WAS DRIVING AND MY GAUGES DROPPED TO ZERO AND MY ENGINE COMPLETELY CUT OUT. AND THAT WAS AFTER MY AIRBAGS SHUT OFF AND MY LIGHTS AND DOOR LOCKS FLICKERED REPEATEDLY. MAYBE THERE'S A SHORT IN A CIRCUIT OR WIRE OR MAYBE IT'S MY ALTERNATOR BUT SERVICES AT A DEALERSHIP ARE HAVING A DIFFICULT TIME FINDING IT. AND AL THESE THINGS HAPPEN WHETHER I'M DRIVING OR STATIONARY. RAIN OR DRY. DOESN'T MATTER. BUT IT'S CLEARLY UNSAFE. AND I HAVE NO CHOICE BUT TO DRIVE IT BECAUSE IT'S MY ONLY MEANS FOR TRANSPORTATION.
