VEHICLE SPEED CONTROL
TRAVELING I-81 S IN MARYLAND, APPROXIMATELY MILE 290, ACCELERATOR STUCK IN FULL THROTTLE. I HAD ACCELERATED TO PASS A CAR, BUT THE ACCELERATOR WENT TO FULL THROTTLE, AND STUCK ON FULL ACCELERATION. I STAYED IN THE LEFT LANE, APPLIED BRAKES SPORADICALLY TO LIMIT THE INCREASED SPEED, AND QUICKLY HIT THE ACCELERATOR PEDAL WITH MY FOOT AND IMMEDIATELY RELEASED SEVERAL TIMES TO TRY TO "BREAK" THE ACCELERATOR FREE. I DID THIS MULTIPLE TIMES WITH NO RESULTS UNTIL FINALLY, WHEN WE WERE AT 94 MPH, THE ACCELERATOR BROKE FREE, AND DISENGAGED. THE BRAKES SMELLED STRONGLY FROM THE EFFORTS TO RETAIN THE ACCELERATION. THE TRUCK HAD APPROXIMATELY 2,300 MILES ON IT WHEN THIS OCCURRED. I HAD PLANNED TO PUT THE TRUCK IN NEUTRAL AND MOVE OFF THE ROAD BEFORE WE HIT 100 MPH. IF MY HUSBAND HAD BEEN DRIVING, HE MIGHT HAVE TURNED OFF THE CAR AND LOST CONTROL (DUE TO LOSS OF POWER). THIS WAS EXTREMELY TROUBLING, AND EXTREMELY DANGEROUS. THANKFULLY, TRAFFIC WAS LIMITED ENOUGH NOT TO CAUSE A WORSE OUTCOME. I CONTACTED MY DEALER AND THE DEALER WHERE I WAS TRAVELING TO.

EXTERIOR LIGHTING
THE HEADLIGHTS ON MY NEW GMC SIERRA 2500HD DENALI ARE HORRIBLE AND UNSAFE FOR DRIVING AT NIGHT. THE 25 WATT RATING AND 2,000 LUMENS ON THE OEM HID BULBS DO NOT PROVIDE ADEQUATE, SAFE LIGHTING FOR OPERATING MY VEHICLE. I ALREADY HIT A DEER WITH MY BRAND NEW TRUCK BECAUSE I COULDN'T SEE IT WELL ENOUGH IN ADVANCE OF THE COLLISION. GMC SHOULD BE HELD ACCOUNTABLE FOR PUTTING SUCH A LOW POWER, POOR QUALITY AND UNSAFE HEADLIGHT IN THEIR $70,000 VEHICLES. I'M RENTING A HYUNDAI WHILE MY TRUCK IS BEING REPAIRED AND THE HEADLIGHTS ON THIS $30,000 FOREIGN CAR ARE 10XS BETTER THAN THE ONES ON MY TRUCK. WHY?

STRUCTURE:BODY
THE PASSENGER SIDE DOOR STRIKERS (BOTH FRONT AND REAR) WERE NOT TORQUED PROPERLY. THE BOLTS SEEM TO HAVE BEEN HAND TIGHTENED ONLY, AND APPEAR TO BE SLOWLY BACKING OUT FURTHER. IF LEFT AS IS, I BELIEVE THE STRIKER WOULD EVENTUALLY BECOME SEPARATED FROM THE VEHICLE BODY, ALLOWING THE DOORS TO OPEN UNEXPECTEDLY. THE ONLY SYMPTOMS OF THE ISSUE WERE: A SLIGHTLY LOUDER RELEASE/CLICK FROM THE DOOR WHEN OPENING (WHEN COMPARED TO DRIVERS SIDE DOORS THAT APPEAR TO BE TORQUED CORRECTLY), DOORS SEEMED TO BE HARDER TO LATCH WHEN CLOSING (HAD TO PULL A LITTLE HARDER THAN DRIVERS DOORS), AND OCCASIONAL COMPLAINTS OF ROAD NOISE FROM PASSENGERS.

POWER TRAIN
UNINTENDED ACCELERATION WHEN SLOWING DOWN TO COME TO A STOP THE VEHICLE WILL OCCASIONALLY ENGAGE A LOWER GEAR VERY SUDDENLY AND LURCH FORWARD. THE RESULTING FORCE IS ENOUGH TO OVERPOWER THE BRAKING EFFORT BEING PROVIDED BY THE DRIVER AND THE VEHICLE WILL MOVE FORWARD SEVERAL FEET BEFORE THE DRIVER CAN REACT AND APPLY MORE BRAKING FORCE TO STOP THE VEHICLE. THE ISSUE OCCURS RANDOMLY AND INFREQUENTLY AT VERY SLOW SPEEDS (5-10MPH). THERE HAVE BEEN SEVERAL OCCASIONS WHERE IVE BEEN BRAKING TO STOP AT A STOP LIGHT AND BEEN FORCED INTO THE MIDDLE OF AN INTERSECTION. IM CONCERNED THE ISSUE COULD CAUSE THE VEHICLE TO STRIKE THE CAR IN FRONT OF IT OR A PEDESTRIAN CROSSING IN FRONT OF THE VEHICLE AS IT STOPS FOR A CROSSWALK. MULTIPLE UNSUCCESSFUL REPAIR ATTEMPTS HAVE BEEN MADE BY THE DEALER. I ATTEMPTED TO FORCE THE MANUFACTURER TO BUY THE VEHICLE BACK FROM ME THROUGH THE MASSACHUSETTS LEMON LAW AND SINCE THAT TIME THEY HAVE DENIED THE EXISTENCE OF A PROBLEM. I HAVE SEEN SEVERAL INSTANCES ONLINE WHERE CONSUMERS WITH THE IDENTICAL VEHICLE (ALL WITH THE 8 SPEED TRANSMISSION) COMPLAINED OF THE SAME PROBLEM.

ENGINE
NOTICED VIVID AND PERSISTENT ENGINE VIBRATION SHORTLY AFTER PURCHASE - WITH NO ASSOCIATED CHECK ENGINE CODE. VIBRATION HAPPENS AT ALL ENGINE AND AMBIENT TEMPERATURES (ESPECIALLY BELOW 50 DEGREES FAHRENHEIT), AT ALL ALTITUDES, REGARDLESS IF IN PARK, NEUTRAL, OR DRIVE. VIBRATION IS SO NOTICEABLE, YOU CAN WATCH THE WAVES VIBRATE THROUGH A CLASS OF WATER WHEN PLACED ON THE DASHBOARD. TAKEN TO TWO DIFFERENT DEALERSHIPS AND BOTH HAVE STATED THE VIBRATION EXPERIENCED IS PER NORMAL DESIGN FOR 6.2L ENGINE. HARD TO BELIEVE GM WOULD DESIGN A $65K+ VEHICLE THAT PURPOSELY VIBRATES/SHAKES. ESCALATED THROUGH GM CORPORATE (SR# 8-3108393XXX), TO WHICH THEY CONFIRMED TRUCK IS RUNNING AS DESIGNED. SINCE THE ENGINE WAS NOT THROWING A CODE, NO FURTHER INVESTMENT/RESOLUTION WAS NEEDED ON THEIR END. THEIR SOLUTION TO ME...SELL THE TRUCK IF NOT HAPPY. OF COURSE THEY DID NOT SAY THAT, BUT THAT'S THE WAY I INTERPRETED THEIR RESPONSE TO MEAN. BUYER BEWARE.

SERVICE BRAKES, SUSPENSION, WHEELS
TOOK TRUCK IN FOR FIRST OIL CHANGE.I HAD SEVERAL PROBLEMS INCLUDING THE BACK TIRES BEING OVER 50% WORN OUT. ALIGNMENT WAS OFF AND DEALER REPAIRED THAT AND ROTATED THE TIRES. NOW WHEN I STOP AT ABOUT 5 MPH THE TRUCK JUMPS. I REMOVED THE ABS FUSE AND PROBLEM GOES AWAY. DEALER STATES THERE IS NO WARRANTY ON TIRES EVEN IF THEY WEAR OUT IN 6000 MILES AND THE PROBLEM WAS THE VEHICLE WASN'T PUT TOGETHER PROPERLY THE FIRST TIME.IF THE ROADS WERE COVERED WITH SNOW I WOULD BE IN REAL TROUBLE.NORMAL HIGHWAY TRAVEL AROUND TOWN

SERVICE BRAKES
WAS STOPPED AT STOP LIGHT,WITH FOOT ON THE BRAKE. STARTED ROLLING FORWARD AND HAD TO PRESS HARDER ON THE BRAKE. WHEN HOLDING FOOT ON BRAKE PEDAL AND IN GEAR PEDAL SLOWLY MOVES DOWN TO THE FLOOR. TOOK VEHICLE TO DEALER WHO WAS LUCKILY CLOSE BY. THEY TESTED TRUCK BRAKE'S AND FOUND THE SAME THING. THEY KEPT TRUCK, AND REPAIRED THE NEXT DAY. MASTER CYLINDER WAS BAD. THEY BELIEVE THAT A SEAL MAY HAVE A CRACK,OR A NICK IN IT, ALLOWING PRESSURE TO RELEASE. THE DEALER SAID MORE THAN LIKELY GM WILL ASK FOR PART TO EXAMINE IT, SO THEY CAN'T TAKE IT APART. TRUCK HAD 3173 MILE'S ON IT.

POWER TRAIN
TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. WHILE DRIVING 30 MPH, THE TRANSMISSION FAILED AFTER A COMPLETE STOP. WHEN THE ACCELERATOR PEDAL WAS DEPRESSED, THE RPMS INCREASED. WHEN SHIFTING FROM SECOND TO FIRST GEAR, THE TRANSMISSION SHIFTED INTO FIRST GEAR WITH EXTREME FORCE AND CAUSED THE VEHICLE TO ABRUPTLY ACCELERATE. THE CONTACT HAD TO ENGAGE THE BRAKE PEDAL WITH FORCE TO AVOID A CRASH. THE FAILURE WAS EXPERIENCED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO WALSH CHEVY BUICK GMC (2330 NORTH BLOOMINGTON STREET, STREATOR, IL, 61364 815-673-4333) WHERE THE TRANSMISSION SYSTEM WAS REPROGRAMMED TWICE AND THE ELECTRONIC CONTROL MODULE WAS REPLACED. HOWEVER, THE FAILURE WAS NOT CORRECTED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 112. UPDATED 08/30/17*LJ *CN

STRUCTURE:BODY, STEERING, SUSPENSION
MY NEW 2017 GMC SIERRA VIBRATES BADLY AT ALL SPEEDS ABOVE 40 MPH. THE SHAKE IN THE STEERING WHEEL CAUSES MY HANDS TO GO NUMB AND IS A SAFETY ISSUE. I HAVE INFORMED GM OF THIS AND HAD IT REPAIRED 3 TIMES. THIS DIDN'T CORRECT THE ISSUE AND GM IS STATING THE VEHICLE IS "OPERATING AS DESIGNED" AND WILL NOT DO ANY FURTHER REPAIRS. IT IS HARD TO BELIEVE THAT IN THIS DAY AND AGE A VEHICLE IS DESIGNED TO HAVE A CONSTANT VIBRATION. THIS ISSUE HAS BEEN GOING ON SINCE MODEL YEAR 2014 AND GM WILL NOT ACKNOWLEDGE OR CORRECT THE ISSUE. IT IS GOING TO TAKE SOMEONE'S SERIOUS BODILY INJURY OR DEATH FOR THEM TO LOOK INTO THE PROBLEM. PLEASE OPEN AN INVESTIGATION INTO ALL GM HALF TON TRUCKS FROM MODEL YEAR 2014 THROUGH 2017.

EXTERIOR LIGHTING
NATURE OF CONCERN: WHEN THE VEHICLE IS PUT INTO REVERSE, THE REAR BACK-UP CAMERA COMES ON. THE DISPLAY OF THE CAMERA IS EXTREMELY TOO BRIGHT, AND MAKES IT DIFFICULT TO BACK UP PROPERLY WITH A GLARING LIGHT IN YOUR FACE. THERE IS CURRENTLY NOT AN OPTION TO DECREASE THE BRIGHTNESS OF THE CAMERA.

SERVICE BRAKES, ENGINE, VEHICLE SPEED CONTROL
MY 2017 GMC 2500 SIERRA DENALI DURAMAX HAS HAD THIS THROTTLE ISSUE, IT SEEMS TO ONLY DO IT WHEN THE EXHAUST STINKS, AND AT SPEEDS BETWEEN 5 - 55 MPH. IF I TAKE MY FOOT OFF THE ACCELERATOR THE TRUCK MAINTAINS RPM (1200 - 1400) OR EVEN HAS INCREASED SOME AND HAS LASTED 2 - 5 SECONDS (ESTIMATED AND GREATLY REDUCES THE EFFECTIVENESS OF THE BRAKING CAPACITY AND RESPONSIVENESS/STOPPING DISTANCE). WORST WAS WITH A HUGE TRAILER BEHIND AND I GOT UP TO SPEED 55 ON COUNTY HWY 8, AND I LET OFF THE ACCELERATOR AND IT KEPT GOING HARD AND I GOT ON THE BRAKES AND I COULDN'T SLOW IT DOWN UNTIL THE TRUCK DECIDED TO RELEASE OFF THE THROTTLE.(TWO WITNESSES IN THE VEHICLE, ONE A GM TECH, STATING YOUR VEHICLE IS NOT SAFE AND NEEDS TO BE LOOKED AT) IT'S HAPPENED ABOUT 25 TIMES IN 5700 MILES IN VARIOUS SETTINGS & SPEEDS AND HAS OCCURRED FREQUENTLY IN TOWN AT SPEEDS OF 25 - 35 MPH. THERE MAYBE SEVERAL HUNDRED MILES IN BETWEEN EPISODES IF YOU WILL, AS THEY OCCUR IN CLUSTERS WHEN EXHAUST STINKS AND GONE WHEN EXHAUST DOES NOT STINK. TRUCK ALSO HAD TORQUE CONVERTER NOT UNLOCK AND [XXX] NEAR CHOKED THE ENGINE OFF AT STOP SIGN RIGHT AFTER A THROTTLE STUCK CONDITION. GOT HOME THE OTHER NIGHT AND FUEL GAUGE STOPPED WORKING! BACK UP CAMERA IS DAYLIGHT BRIGHT AT NIGHT, LOW COOLANT ISSUES, MAP SENSOR ISSUE, ENGINE SURGED THE OTHER DAY, WHAT NEXT? IT'S CONSTANTLY BEEN AT DEALERSHIPS WITH NO ANSWERS. MY WIFE WON'T DRIVE IT ANYMORE AND WISHES I WOULDN'T EITHER FEARING IT WILL CAUSE AN ACCIDENT AND SHE'S PROBABLY RIGHT. GM HAS STATED THEY ARE AWARE OF THE PROBLEM BUT WILL NOT PROVIDE ANY TRADE IN ASSISTANCE DOLLARS TO GET IT OFF THE ROAD AND THERE IS NO FIX. $70,000+ TRUCK, LIVES AT RISK AND NO SERIOUS RESPONSE FROM GM?

ENGINE
THE VEHICLE WHICH HAS UNDER SEVEN HUNDRED MILES ON IT DOES THE FOLLOWING: WHEN I TRY TO ACCELERATE THE VEHICLE STARTS TO MISFIRE, STARTS TO CHUG AND JERK, IT STARTS TO HESITATE AND BECOMES ROUGH. WHEN I CALLED GMC SERVICE DEPARTMENT I WAS TOLD THERE WAS A CODE FOR THIS PROBLEM #PIP5457B BUT THAT CURRENTLY THERE IS NO KNOWN REASON AND NO KNOWN REPAIR AND NO KNOWN COMPUTER CODE TO REPAIR THE PROBLEM. I TRIED TO MERGE ONTO THE INTERSTATE HIGHWAY AND NEEDED TO SPEED UP BUT THE TRUCK STARTED TO LURCH; I NEARLY GOT REAR ENDED. I CAN'T DRIVE UP A HILL IN THE CITY OR ON THE INTERSTATE AND KEEP UP WITH THE FLOW OF TRAFFIC BECAUSE THE TRANSMISSION STARTS TO SPUTTER. MY WIFE AND I ARE AFRAID TO DRIVE THIS VEHICLE. WE JUST PAID NEARLY $49,000 FOR THIS GMC SIERRA 2017 AND ONLY OWNED IT FOR ONE WEEK WHEN THIS STARTED TO HAPPEN. IT DOES THIS ALL THE TIME. VERY DANGEROUS!
