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.

  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.

  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.

• 03/31/2016· SERVICE BRAKES

  I HAVE BEEN HAVING A PROBLEM WITH THE TRAILER BRAKE CONTROLLER ON MY K3500 TRUCK. RECENTLY THE MESSAGE "CHECK TRAILER WIRING" HAS BEEN COMING ON FREQUENTLY. AT THE SAME TIME, THE BRAKING CONTROLLER SHUTS OFF POWER TO THE TRAILER BRAKES. THIS HAS RESULTED IN A VERY UNSAFE CONDITION, ESPECIALLY WITH A TRAILER THAT WEIGHS OVER 14,000 POUNDS. THIS HAS BEEN GOING ON FOR 6 MONTHS NOW. REPEATED ATTEMPTS BY BOTH THE GMC DEALER AND THE TRAILER DEALER HAVE FAILED TO RESOLVE THE PROBLEM. I HAVE BEEN TOLD, BY THE DEALER, THAT THE PROBLEM STARTED APPROXIMATELY WITH THE 2014 MODELS. THE BRAKE CONTROLLER HAS BEEN UPGRADED, AND MADE MUCH MORE SENSITIVE TO SLIGHT DEVIATIONS IN THE TRAILER SYSTEM, CAUSING THE CONTROLLER TO "SHUT OFF" SO TO SPEAK. WHILE THIS WOULDN'T BE A BIG ISSUE NORMALLY, WHEN IT SHUTS OFF, YOU LOSE ALL BRAKING ABILITY TO THE TRAILER RESULTING IN AN UNSAFE CONDITION. THERE IS NO WAY TO OVERRIDE THIS AND ACTIVATE THE BRAKES. WHAT SEEMS TO BE HAPPENING IS A VERY SLIGHT DEVIATION IN THE RESISTANCE IN THE TRAILER BRAKE SYSTEM (BY 1 OHM OR LESS) AND THAT CAUSES THE "SHUTDOWN" IN THE CONTROLLER. TRAILER BRAKES WOULD WORK, IF THEY COULD GET POWER. BUT, THE CONTROLLER HAS SHUT DOWN, SO NO POWER. MYSELF (AND THE TRAILER SHOP) HAVE BEEN CHECKING THE INTERNET AND FINDING THAT THIS IS NOT AN ISOLATED INCIDENT. IT APPEARS TO BE HAPPENING WITH ALL THE BIG THREE MANUFACTURER TRUCKS, SINCE ABOUT 2014. PEOPLE HAVE BEEN COMING UP WITH SOME RATHER "CREATIVE" WAYS AROUND THIS, IN SOME CASES ELIMINATING THE ORIGINAL SYSTEM ENTIRELY. THIS IS JUST NOT ACCEPTABLE. AGAIN, THIS "NEW SYSTEM THE BIG THREE ARE PUTTING IN IS FAR WORSE THAT THE OLD, SIMPLY BECAUSE IT HAS NO ROOM FOR FORGIVENESS IN A TRAILER SYSTEM THAT MIGHT WORK OTHERWISE, BUT HAS A SLIGHT DEVIATION IN WHAT IS CONSIDERED "ACCEPTABLE" TO THE CONTROLLER. AT THE VERY LEAST, THERE SHOULD BE A FAIL SAFE METHOD.

  TL* THE CONTACT OWNS A 2015 GMC SIERRA. THE CONTACT STATED THAT THE HEADLIGHTS LOW BEAM FAILED TO PROVIDE ADEQUATE LIGHT COVERAGE MAKING IT VERY DIFFICULT TO DRIVE AT NIGHT AND THE HIGH BEAM ALSO FAILED TO PROVIDE SUFFICIENT LIGHT COVERAGE. THE DEALER ADVISED THAT THE HEADLIGHTS WERE OPERATING AS DESIGNED. THE HEADLIGHTS WERE NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 731.

  HEADLIGHTS HAVE BEEN ADJUSTED BY THE DEALER TWICE. THE HEADLIGHTS ARE A SINGLE BULB DESIGN (LOW AND HIGH BEAMS FROM ONE BULB). IF LOW BEAMS ARE ADJUSTED TO ADEQUATELY SEE THE ROAD DURING NIGHT DRIVING THE HIGH BEAMS POINT INTO THE AIR (APPROX. 10 FEET IN THE AIR AT 100 FEET FROM THE VEHICLE). IF THE BEAMS ARE ADJUSTED TO ALLOW THE HIGH BEAMS TO ILLUMINATE THE ROAD PROPERLY; WHEN SWITCHED TO THE LOW BEAMS THERE IS INSUFFICIENT LIGHT ON ROAD TO DRIVE SAFELY AT 55 MPH. *TR

  The contact owns a 2015 GMC Sierra.

The vehicle returned to normal functionality, but the failure became a regular occurrence. The power steering warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 18V586000 (Steering), but the VIN was not included. The manufacturer was notified of the failure but did not assist. The failure mileage was 90,000.

  VEHICLE LOW BEAM HEAD LIGHTS HAVE VERY POOR COVERAGE AND BRIGHTNESS. WHEN DRIVING AT NIGHT. THEY BARELY LIGHT THE ROAD IN FRONT OF THE VEHICLE AND COVERAGE SIDE TO SIDE IS VERY WEAK. ADDITIONALLY WHEN IT IS RAINING OUT, IT IS LIKE DRIVING WITH NO HEADLIGHTS ON AT ALL. TO HAVE BETTER HEAD LIGHTS I WOULD HAVE HAD TO BUY SPECIAL LIGHTING OPTION AVAILABLE ONLY ON A HIGHER-UP MODEL OF GMC SIERRA TRUCK. ALL MODELS OF GMC SIERRA 2015 TRUCKS SHOULD HAVE ADEQUATE HEADLIGHTS WITHOUT HAVING TO BUY THE TOP/ MORE EXPENSIVE MODEL TO GET THEM. GMC SHOULD BE REQUIRED TO RECALL ALL GMC SIERRA 2015 TRUCKS AND REFIT THEM WITH ADEQUATE LIGHTING BEFORE BAD ACCIDENTS OCCUR AS A RESULT OF THIS DEFICIENCY. I HAVE NEVER EXPERIENCED SUCH POOR LIGHTING WITH A VEHICLE DRIVING AT NIGHT OR IN RAIN. IT IS UNACCEPTABLE ON A NEW GMC TRUCK. *TR
