2015 GMC Sierra 3500 Problems

HEADLIGHTS NOT BRIGHT ENOUGH TO SEE IN THE NIGHT

HEADLIGHTS ON THIS TRUCK HAVE ALWAYS BEEN WEAK, DISTANCE IS NOT LIT UP AND IN RAINY WEATHER ON THE HIGHWAY IS VERY POOR EVEN WITH FOG LIGHTS ON. THE HELP FROM THE FOG LIGHTS IS MINIMAL. THIS IS A KNOWN PROBLEM BY THE MANUFACTURER AND IS REPEATED MANY MANY TIMES ON VARIOUS GM RELATED OWNER FORUMS. THIS IS A SAFETY ISSUE AND NEEDS TO BE ADDRESSED AND CORRECTED BY THE MANUFACTURER.

The contact owns a 2015 GMC Sierra 3500. The contact stated while driving approximately 70 MPH, the vehicle abruptly lost motive power and decelerated to 25 MPH. The contact stated that the message “Engine Power Reduced” was displayed. The contact stated that the failure was intermittent, but always occurred while driving at high speeds. The contact had taken the vehicle to a local dealer however, the failure could not be duplicated. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was 48,815,

Vehicle has a cp4 fuel pump. This pump has a high failure rate. Upon failure the vehicle shuts down and cannot be restarted. This can happen at any time and anywhere. Can happen while on a highway or freeway. This vehicle is used to haul heave loads. This failure can ending up to $10,000 or more to repair. This failure has not happened on this vehicle yet. Am very concerned about me safety and the safety of others because of the high failure rate.

The service trailer brake icon keeps appearing on my screen I’m afraid it’s going to not work properly when towing trailers it’s constantly going on and off I believe it’s the brake control module switch but also could be in the harness just want Gm to be aware of the many blogs that I have read about with this problem The problem first appeared about two months ago

The contact owns a 2015 GMC Sierra 3500. The contact stated while driving 55 MPH, another vehicle merged into the lane that the contact was driving in and the contact pressed on the horn pad however, there was no sound coming from the horn. The vehicle was taken to an independent mechanic and the horn was replaced. The contact stated the failure had occurred several times and the horn was replaced each time. The manufacturer was contacted and stated there was no recall related to the failure and offered no additional assistance. The failure mileage was 120,000.

4 weeks ago, constant repeated loud chime and visual warning stating " service trailer brake system". This is constantly alarming and unable to be cancelled or acknowledged throughout the drive. This results in distracted driving. Furthermore, it occurs both when towing a trailer or not towing. I have noticed decreased braking of the trailer as well. Have not gone to dealer yet.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 3500. THE CONTACT STATED HER HUSBAND WAS DRIVING AT 20-30 MPH AND HAULING A TRAILER, THE DRIVER ENTERED THE HIGHWAY, MADE A RIGHT TURN AND THE VEHICLE LOSS OF POWER STEERING ASSIST AND BECAME DIFFICULT TO STEER. THE VEHICLE WAS TOWED TO CAVENDER BUICK GMC WEST (7400 TX-1604 LOOP, SAN ANTONIO, TX 78254) TO BE DIAGNOSED. THE DRIVER WAS INFORMED THAT THE POWER STEERING NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE CONTACT REFERENCED THE FAILURE TO (NHTSA CAMPAIGN NUMBER: 14V719000 (STEERING) HOWEVER THE VIN WAS NOT INCLUDED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 33,000.

I WAS TRAVELING ON A BUSY ROADWAY AT 40 MPH WHEN FUEL FILTER WARNING LIGHT CAME ON SUDDENLY AND VEHICLE LOST ALL POWER - INCLUDING THE LOSS OF POWER STEERING AND POWER BRAKING. THANKFULLY I HAD NOT YET ENTERED THE HIGHWAY AND WAS ABLE TO SLOW VEHICLE DOWN BUT WITH GREAT DIFFICULTY AND NOT INJURE ANYONE AROUND AND THAT DAY WAS NOT TOWING A LOAD. VEHICLE WOULD NOT RESTART. I HAD IT TOWED TO NEAREST DEALERSHIP WHO THEN INFORMED ME THAT THE "BOSCH CP4 FUEL PUMP" HAD EXPLODED SENDING METAL SHRAPNEL THROUGHOUT THE ENTIRE ENGINES FUEL SYSTEM. THE ONLY FIX WAS THE ENTIRE REPLACEMENT OF THE FUEL SYSTEM AT A COST OF OVER $11K. I HAD JUST PURCHASED THE TRUCK 3 MONTHS PRIOR. UPON HEARING THIS, I SEE THIS HAS BEEN A FREQUENT SAFETY PROBLEM AFFECTING A WHOLE LINE OF 2011 - CURRENT GM, FORD, DODGE, AND JEEP DIESEL VEHICLES EQUIPPED WITH THE CP4 PUMPS. THERE ARE NUMEROUS LAWSUITS UNDERWAY FOR THIS FAILURE INCLUDING ONE OF A MAJOR ACCIDENT WHILE TOWING (WHAT THESE TRUCKS ARE MADE FOR) BECAUSE OF LOSS OF POWER STEERING AND BRAKING UPON ENGINE STALL AFTER FUEL PUMP EXPLOSION. THE GM TECHNICAL SERVICE BULLETIN FOR REFERENCE IS #16-NA-102. IN ADDITION, THE NHTSA HAS RECEIVED TWO MANUFACTURER TECHNICAL SERVICE BULLETINS ON THIS VERY SAFETY ISSUE. THIS IS VERY MUCH A RECALL WORTHY SAFETY ISSUE. LOSING ENGINE POWER AND LOSS TO ALL POWER STEERING AND POWER BRAKING IN THESE VEHICLES IS BEYOND DANGEROUS. IN ADDITION, WHEN IT IS HAPPENING TO VEHICLES DESIGNED TO TOW WEIGHTS IN EXCESS OF 30K POUNDS TRAILER LOAD BEHIND THE AFFECTED VEHICLE THE DANGER IS AMPLIFIED THAT MUCH GREATER. PLEASE ISSUE A RECALL IMMEDIATELY. PEOPLE'S LIVES ARE VERY MUCH AT STAKE FOR GM'S FAILURE TO REMEDY A KNOWN SAFETY ISSUE. GM LISTS IT AS ONLY A "HARD START OR NO START". THEY DO NOT RECOGNIZE IN WRITING THE DANGER OF FULL POWER LOSS AT HIGHWAY SPEEDS WHICH IS MOST OFTEN HOW IT PRESENTS ITSELF.

SITTING IN A PARKING LOT ALLOWING THE PICKUP TO WARM UP, THE REAR DEFROSTER WAS ON AND STARTED HAVING A CRACKLING SOUND AND SMOKING. THE NOISE AND SMOKE STOPPED WHEN THE REAR DEFROSTER WAS TURNED OFF, HOWEVER APPROXIMATELY A MINUTE LATER THE WINDOW SHATTERED AND SPRAYED GLASS SHARDS INTO THE CAB AND ON THE BACK SEAT. THE PICKUP WAS STATIONARY AND THERE WAS NO POSSIBILITY THAT THIS WAS CAUSED BY AN IMPACT. BASED ON THE PATTERN OF BROKEN GLASS IT COULD BE SEEN COMING FROM THE CORNER OF THE WINDOW WHERE THE HEATING ELEMENT IS. I CALLED GM AND THEY INDICATED THEY WOULD NOT LOOK AT THE VEHICLE FOR AT LEAST 30 DAYS TO EVEN DETERMINE THE ISSUE.

THE NEW TOW MIRRORS ON THIS TRUCK HAVE LED BLINKERS THAT ARE SO BRIGHT YOU CAN'T TELL IF SOMEONE IS COMING TOWARDS YOU WHEN YOU HAVE THE BLINKER ON. IT'S FLASHING RIGHT IN YOUR FACE. *TR

THIS VEHICLE HAS HAD NUMEROUS ELECTRICAL ISSUE FROM THE FIRST FEW MONTHS OF OWNERSHIP. THE TRAILER BRAKE SYSTEM FAILED AND WAS REPLACED ON OCTOBER 2014. THE VEHICLE HAS HAD MANY RECALLS THAT HAVE BEEN CORRECTED BY OWNER AND SERVICE PROVIDER. THE SECOND SUMMER OF OWNERSHIP THE VEHICLE HAD RADIATOR ISSUES, AND MOST RECENTLY ELECTRICAL ISSUES AGAIN AND TRANSMISSION ISSUES. WHILE DRIVING THE VEHICLE ELECTRICAL DASHBOARD GOES INTO A FLICKER AND SHUTS DOWN. GMC WAS ABLE TO FIX THIS ISSUE AT THE OWNERS COST WITH THE VEHICLE BEING OUT OF SERVICE FOR 3 WEEKS. GMC WAS TO REIMBURSE THE OWNER FOR COSTS OF A GM DEALER THAT WAS NOT ABLE TO FIX THE ISSUE (PAINTER AUTOMOTIVE)(FEBRUARY 9, 2017) OF $300, THIS HAS NOT BEEN REIMBURSED. THE VEHICLE IS NOW AT THE SERVICE STATION AS IT DOES NOT START WITH NO CODES. IT HAS BEEN OUT OF SERVICE FOR 2 WEEKS AND COUNTING, THIS VEHICLE IS NO LONGER RELIABLE OR SAFE FOR US TO DRIVE. WE HAVE DOCUMENTATION OF ALL THE ISSUES AND VIDEO OF THE DASHBOARD FLICKER.

THIS HAS BEEN GOING ON FOR OVER SIX MONTHS NOW, EVERY DAY! ALL DAY LONG!! HAVE CONTACTED GMC OVER AND OVER, HAVE BEEN TO THEIR SHOPS OVER AND OVER! , THEY LAUGH AT ME , AND TELL ME NOTHING IS WRONG EVERY TIME. FCC, ONSTAR, S. XM RADIO, ALL REFUSE TO HELP ME WITH THIS PROBLEM, OVER AND OVER , MY VEHICLE STARTS TO SMOKE WHEN THEY ARE DOING THIS, THEY ARE BESIDE ME LAUGHING WITH THEIR CELL PHONES IN HAND. I AM GOING TO RECORD THIS AND THEN FILE SUIT AGAINST EVERY ONE OF THEM!!!!

I SEE THERE WAS A RECALL FROM GM #17399 FOR THE 2015 DUAL FUEL TANK SENDING UNIT PROBLEM. THIS IS ONLY FOR THE 6.0 L GAS ENGINE. I HAVE THE DURAMAX 6.6L ENGINE IN MINE. I HAD THE SAME PROBLEM WITH MINE. THE SENDING UNIT DID NOT TURN OFF THE TRANSFER PUMP AND OVERFILLED THE FRONT TANK CAUSING FUEL TO POUR OUT ALL OVER THE ROAD. I CAUGHT IT BEFORE THE DRIVE LINE CAUSED ANY DAMAGE. I HAD IT TOWED TO THE DEALER AND WHILE WE MOVED IT TO PULL IT UP ON THE TOW TRUCK IT WAS PUSHING FUEL OUT OF THE FILLER NECK OF THE FRONT TANK. THE DEALER SHIP REFUSED TO COVER THE COST SAYING ITS NOT PART OF THE RECALL. THEY SAID IT WASN'T THE SAME PROBLEM. IT SURE WAS. I HAVE ATTACHED THE REPAIR ORDER AND THE RECALL NOTIFICATION BELOW. I AM WONDERING IF IT IS PART OF THE RECALL AND THEY ARE JUST NOT DOING THEIR JOB AND HONERING IT.

VEHICLE WAS DELIVERED TO ME WITH PHYSICAL DAMAGE THE ONE OF THE SHOCKS. PART OF THE SHOCK TUBE IS CRUSHED IN, UP HIGH AWAY FROM THE ROADWAY. MOST LIKELY CAUSE IS DAMAGE DURING VEHICLE TRANSPORTATION FROM FACTORY. TWO DEALERSHIPS HAVE CONFIRMED THIS IS THE MOST LIKELY AND POSSIBLE CAUSE. I HAVE BROUGHT THE VEHICLE IN AT LEAST 3 TIMES TO A DEALER, AND HAVE BEEN TOLD THAT ONLY THE DEALERSHIP I PURCHASED THE VEHICLE FROM CAN PERFORM THE WARRANTY WORK FOR THIS REPAIR. I HAVE ALSO CALLED GMC CUSTOMER SERVICE NUMBER IN THE OWNERS MANUAL AND MADE A COMPLAINT THERE AS WELL. I WAS TOLD THE SAME THING BY THE PERSON HANDLING THE COMPLAINT, THAT I WOULD HAVE TO TAKE THE VEHICLE TO THE DEALERSHIP THAT I PURCHASED IT FROM. THE PERSON SAID THEY WOULD LOOK INTO IT FURTHER, BUT NEVER CALLED ME BACK. THE DEALERSHIP I PURCHASED THE VEHICLE FROM IS LOCATED IN ANOTHER STATE, HUNDREDS OF MILES AWAY. IT IS NOT PRACTICAL TO DRIVE HUNDREDS OF MILES AWAY WHEN A LOCAL DEALERSHIP CAN PERFORM WARRANTY WORK.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 3500. THE CONTACT STATED THAT TWO OF THE FIVE SEAT BELTS IN THE VEHICLE FAILED TO PROPERLY RETRACT AND SECURE.

BEAMAN BUICK GMC (1531 BROADWAY, NASHVILLE, TN 37203, (615) 251-8400) INDICATED THAT THEY WOULD ORDER THE SEAT BELT KIT, BUT DID NOT CONFIRM THE QUANTITY. THE DEALER DID NOT STATE WHETHER THE PART WAS AVAILABLE. THE CONTACT WAS CONCERNED THAT THE SEAT BELTS COULD FAIL IN THE EVENT OF A CRASH. A LOANER VEHICLE WAS NOT OFFERED WHILE WAITING TO RECEIVE THE PART. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND ISSUED NHTSA CAMPAIGN NUMBERS: 17V437000 (AIR BAGS, SEAT BELTS), 16V651000 (AIR BAGS, SEAT BELTS), AND 14V301000 (ELECTRICAL SYSTEM, SEAT BELTS).
