POWER TRAIN
Previous years of my truck with the Allison “branded” transmission have been reported to lock up while driving. From what I can gather there was a recall. Instead of fixing the issues with the transmission a program was installed to put the transmission in limp mode during the failure. My model, a 2023 apparently came with the limp mode feature already installed. When my transmission failed it took the truck out of gear and locked up for a moment before I could safely pull over.

ENGINE, POWER TRAIN, SUSPENSION
I'VE HAD SEVERAL PROBLEMS WITH THE TRUCK SINCE I BOUGHT IT 3 MONTHS AGO. I'VE FIXED ALMOST ALL OF THEM-ABS WAS ACTIVATING WHICH WAS PUSHING ME INTO TRAFFIC NEARLY CAUSING A WRECK SO I CHANGED THE ABS SPEED SENSOR AND HUB ASSEMBLY. FRONT SUSPENSION WAS GONE SO I REPLACED THAT; AS WELL AS STEERING PARTS, BRAKES, THE PARKING BRAKE DOESN'T WORK, FIXING IT NEXT. OIL SENDING UNIT, A/C BELT AND REFRIGERANT REPLACED. THE PROBLEMS LEFT ARE EVAP EMISSION VENT VALVE SOLENOID, THROTTLE PEDAL POSITION SENSOR, AND RANDOM/ MULTIPLE CYLINDER MISFIRE SOMETIMES AND CYLINDER 4 MISFIRE OTHER TIMES. IN 4X4 WHEN IT GETS UNDER A LOAD SOMETHING SOUNDS LIKE IT'S BINDING UP AND IT POPS BUT IT STILL WORKS. WHEN I SHIFT INTO DRIVE OR REVERSE OR ACCELERATE FROM A STOP IT HAS A SHIFT FEELING IN THE REAR WITH A THUMP SOUND. SOMETIMES I CAN PUSH THE GAS AND IT WON'T DOWNSHIFT TO SPEED UP WHEN I'M ON THE HWY BUT THAT'S PROBABLY THE TPPS. I JUST WANT MY 4X4 WORKING AND MY SHIFT THUMP FROM A STOP TO GO AWAY. HELP. IN 4X4 THE NOISE HAPPENS IN FWD REVERSE AND WHEN TURNING AND WORSE IN 4LO BUT HAPPENS IN 4HI AND AUTO BUT NOT IN 2HI. *TR

AIR BAGS
I BOUGHT THIS TRUCK FROM A USED CAR DEALERSHIP IN BLAIR, NE WASHINGTON COUNTY. THE DEALERSHIP SOLD THIS TRUCK TO ME WITH REPLACED AIRBAGS THAT DIDN'T WORK. THEY REPLACED THE ORIGINAL FACTORY AIR BAGS WITH WHAT NOW ARE MARKED CHEVROLET AND NOT GMC ACCORDING TO MECHANICAL SHOP. SAME MECHANIC EXPRESSED TO ME THAT THIS TRUCK WAS IN ACCIDENT THAT NOT ONLY BENT THE FRAME BUT ALSO CAUSED THE ORIGINAL AIR BAGS TO DEPLOY. WHEN I PICKED UP TRUCK AFTER SALE I ASKED THE DEALERSHIP OWNER WHY THE LIGHT WAS ON, HE SAID HIS MECHANIC COULD FIX IT. HIS MECHANIC COULD ONLY WORK MONDAY THRU THURSDAY WHICH MADE MAKING ANY APPOINTMENT IMPOSSIBLE FOR ME, SO I TOOK IT TO AN AUTHORIZED DEALER TO LOOK AT IT AND THAT IS WHEN I FOUND THE AIRBAGS HAD BEEN REPLACED IMPROPERLY. I FILED A COMPLAINT WITH THE NE DEPARTMENT OF VEHICLES AND WAS TOLD TO FILE A FEDERAL COMPLAINT ABOUT THE AIRBAGS. THANK YOU FOR YOUR TIME

SERVICE BRAKES, ELECTRICAL SYSTEM
TL* THE CONTACT OWNS A 2000 GMC SIERRA 1500. THE CONTACT STATED THAT THE VEHICLE WAS REPAIRED PER NHTSA CAMPAIGN NUMBER: 05V379000 (SERVICE BRAKES, HYDRAULIC) BY WEHR FORD (11311 US-60 BUS, MOUNTAIN GROVE, MO 65711, (417) 926-3192). THE CONTACT STATED THAT THE DEALER ONLY CLEANED THE ABS SENSOR FOR CORROSION. YEARS LATER, THE BRAKE PEDAL FAILED TO RESPOND DUE TO INTERNAL CORROSION REGARDING THE SENSOR. ALSO, THE ABS KEPT INTERMITTENTLY ACTIVATING AND CAUSED EXTREME DIFFICULTY WHEN BRAKING. THE BRAKE PEDAL FAILED TO STOP THE VEHICLE AND CAUSED THE DRIVER TO HAVE TO REVERSE MORE THAN TWICE TO PREVENT A CRASH. THE DEALER WAS NOTIFIED OF THE FAILURES AND INDICATED THAT THE ABS SENSOR MAY NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS NOT AVAILABLE.

SERVICE BRAKES
WENT TO STOP AND THE BRAKE PEDAL PUSHED AGAINST MY FOOT INSTEAD OF GOING DOWN. WAS MOVING SLOWLY AND THE BRAKE PEDAL INSTEAD OF STOPPING THE CAR PUSHED MY FOOT UP FROM THE BRAKE PEDAL AND I WENT OVER A PARKING BRAKE. MECHANIC VERIFIED THAT WHEN WHEEL SENSOR GOES BAD THE VEHICLE THINKS THE BRAKES ARE LOCKING UP AND THE ABS SYSTEM GOES ON PUMPING BRAKE PEDAL. HAPPENED MULTIPLE TIMES AS APPROACHED STOP LIGHTS PUSHING ME INTO INTERSECTION INSTEAD OF STOPPING.. I BELIEVE WHEN THE WHEEL SENSOR IS BAD IT SHOULD NOT PUT ME OR OTHERS IN A DANGEROUS SITUATION.

SERVICE BRAKES
DURING A NORMAL STOP AT A STOP SIGN ON A RURAL ROAD, A STEEL BRAKE LINE RUPTURED DUE TO EXCESS CORROSION. THIS ONE LINE BETWEEN THE MASTER CYLINDER AND ABS MODULE IS THE ONLY LINE THAT PROVIDES PRESSURE TO THE FRONT BRAKES, WHICH SUPPLY ROUGHLY 75% OF THE VEHICLE'S BRAKING POWER. THE RUPTURE RESULTED IN RAPID FLUID LOSS AND THEREFORE A LACK OF PRESSURE IN THE HYDRAULIC SYSTEM TO ALLOW FOR ADEQUATE BRAKING. NEEDED TO SWERVE INTO A DITCH TO AVOID A CRASH WITH CROSS TRAFFIC.VISUAL INSPECTION INDICATES MOST BRAKE LINES ARE EXTREMELY CORRODED, AND WERE OBVIOUSLY MADE WITH SUBSTANDARD MATERIALS AS COMPARED TO OTHER MANUFACTURERS. I DO RECOGNIZE THAT THIS IS AN OLD VEHICLE, HOWEVER OTHER VEHICLES OF SIMILAR AGE AND DRIVEN IN SIMILAR ENVIRONMENTS DO NOT HAVE THIS ISSUE. ONLINE RESEARCH, MOST NOTABLY THE COMPLAINTS FILED TO NHTSA, INDICATE THIS IS A COMMON PROBLEM WITH CHEVY/GMC TRUCKS OF THIS ERA. ALTHOUGH OTHER OEM'S (SUBARU) HAVE ISSUED RECALLS IN SIMILAR SITUATIONS, IT APPEARS THAT THE GM THAT THE PUBLIC BAILED OUT JUST A FEW YEARS AGO HAS DECIDED TO DENY THAT THIS IS A PROBLEM, GAMBLING THAT THE THE COST OF LAWSUITS ASSOCIATED WITH DEATHS DO NOT EXCEED THE COST OF A RECALL.

FAULTY INSIDE DOOR HANDLES AND MECHANICISMS.THE DOOR HANDLE ITSELF WILL BREAK OR THE CONNECTING MECHANISM WILL BREAK NOT ALLOWING THE OCCUPANTS ANY ABILITY TO LEAVE FROM THE VEHICLE IN CASE OF AN EMERGENCY OR OTHERWISE CAUSING THEM TO BE TRAPPED INSIDE. THIS IS PARTICULARLY DANGEROUS IN A FIRE, SUBMERGED IN WATER OR WINDOWS FREEZING SHUT FROM ICE OR SNOW.

SERVICE BRAKES, ELECTRICAL SYSTEM
WHILE DRIVING THE BRAKE AND ABS LIGHTS ON THE INSTRUMENT PANEL LIGHT UP. THIS HAS OCCURRED WHILE DRIVING OF THE FREEWAY AND ON CITY STREETS. SOMETIMES THESE LIGHTS GO OFF AND SOMETIMES THEY REMAIN LIGHTED. WHEN THIS HAPPENS I FEAR THAT THERE IS A PROBLEM WITH THE BRAKES AND HAVE TAKEN THIS MATTER TO A MECHANIC. THE BRAKES WERE EXAMINED AND HE FOUND NOTHING WRONG. THIS IS VERY STARTLING TO THE DRIVER AND OF GREAT CONCERN. THIS APPEARS ON INTERNET SEARCHES AND IT APPEARS THAT 100,000 PLUS INDIVIDUALS HAVE THIS PROBLEM. I HAVE CONTACTED THE DEALER AND OBVIOUSLY THIS MATTER HAS BEEN BROUGHT TO THERE ATTENTION. YET THEY CLAIM THEY ARE UNFAMILIAR AND WANT TO CHARGE $600 TO DIAGNOSE AND THEN LIKELY MORE TO FIX. THIS IS OBVIOUSLY A LIE AS THERE IS NO WAY THAT ONE COULD BE READING SO MUCH ABOUT THIS ON THE INTERNET IF IT WAS NOT A PROBLEM IN THE GMC SIERRA TRUCKS. SOME CLAIM IT IS A FAULTY CIRCUIT BOARD WHILE OTHERS HAVE LOST THE USE OF THEIR BRAKES. THIS IS OF GREAT CONCERN. THIS OCCURS WHILE DRIVING AND THE VEHICLE IS IN MOTION AND SOMETIMES AT HIGH SPEEDS ON A FREEWAY.

SERVICE BRAKES
BRAKE FAILURE FOR THE SECOND TIME ON THE VEHICLE. ORIGINAL BRAKE LINES WERE REPLACED 7 OR 8 YEARS AGO DUE TO FAILURE AT MY OWN COST (RUSTED LINES, LEADING THEM TO FAIL AS THE BRAKES WERE APPLIED), ALL LINES WERE REPLACE WITH GM REPLACEMENT LINES BY A QUALIFIED TECHNICIAN. ORIGINAL FAILURE RENDERED THE BRAKES 0% OPERATIONAL, GRAVITY (UPHILL) WAS THE ONLY THING THAT STOPPED THE VEHICLE. THE MOST RECENT FAILURE (ON JULY 29, 2017) AFFECTED THE BRAKE LINE RUNNING TO THE FRONT-RIGHT CALIPER, LINE FAILED WHERE IT CROSSED OVER THE SKID PLATE NEAR THE CENTER-LINE OF THE VEHICLE UP FRONT BY THE LOWER RADIATOR SUPPORT. LINE FAILED DUE TO CORROSION. REAR BRAKES APPEAR TO BE WORKING BUT ARE NOT SUFFICIENT TO STOP THE VEHICLE IN A SAFE MANNER. NO ACCIDENT OCCURRED, LINE FAILED AS APPROACHING A LIGHT TURNING RED WHILE GOING UPHILL, ROLLED THROUGH THE INTERSECTION PRIOR TO THE LIGHT TURNING GREEN FOR CROSSING TRAFFIC AND WAS ABLE TO STOP THE VEHICLE AS IT DRIFTED TO A STOP UPHILL. THE QUALITY OF THE GM BRAKE LINES ARE VERY SUSPECT TO SAY THE LEAST. THE BRAKE LINES ARE DANGEROUS AND SEEM TO BE MORE SUSCEPTIBLE TO CORROSION THAN ANY OTHER BRAKE LINE ON ANY OTHER VEHICLE I'VE EVER OWNED, OR ANY OF MY FRIENDS OR FAMILY HAVE EVER OWNED. I CAN ONLY IMAGINE IF THE LINES FAILED UNDER DIFFERENT CIRCUMSTANCES (WHILE TOWING THOUGH MOUNTAINS WHILE GOING DOWNHILL FOR EXAMPLE, THIS WOULD BE A LIFE-THREATENING SITUATION). PLEASE DETERMINE IF THESE LINES ARE FAULTY FOR THE SAKE OF OTHERS WITH THESE VEHICLES, AND THE SAKE OF OTHER MOTORISTS THAT COULD BE IMPACTED WHEN THE BRAKES ON THIS LARGER VEHICLE FAIL. IF THEY ARE FOUND TO BE FAULTY OWNERS SHOULD BE NOTIFIED THAT THESE BRAKE LINES ARE SUBPAR, AND THAT THE MANUFACTURER'S REPLACEMENT LINES ARE ALSO SUBPAR.
