2000 GMC SIERRA 1500 Power Train Problems

THE NP246 TRANSFER CASE OIL PUMP PLATE WEARS A HOLE INTO THE CASE, CAUSING IT TO LEAK. THERE IS A SAVER PLATE THAT CAN BE INSTALLED THAT PREVENTS THIS PROBLEM.

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...

TL* THE CONTACT OWNS A 2000 GMC SIERRA 1500. WHILE DRIVING 50 MPH, THE VEHICLE HAD A SUDDEN LOSS OF POWER STEERING AND THE BRAKES FAILED TO ENGAGE WITHOUT WARNING. THE CONTACT MENTIONED THAT THE VEHICLE WOULD VEER TO THE RIGHT INDEPENDENTLY. AS A RESULT, THE VEHICLE CRASHED INTO A CONCRETE BARRIER AND SPUN AROUND FROM THE FRONT AND CRASHED IN THE REAR. THE DRIVERS SIDE AND FRONT PASSENGER SIDE AIR BAGS DEPLOYED. THE CONTACT SUSTAINED A DISLOCATED LEFT SHOULDER AND A FRACTURED RIGHT FOOT. THE CONTACT ALSO SUSTAINED WHIPLASH, NECK PAINS WHICH REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE CONTACT WAS NOT INCLUDED IN NHTSA CAMPAIGN ID NUMBER: 05V005000 (POWER TRAIN) AND NHTSA ACTION NUMBER: EA04012 (SERVICE BRAKES, HYDRAULIC, STEERING). THE VEHICLE WAS TOWED TO THE CONTACTS RESIDENCE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 183,500.

WHILE TRYING TO SELL MY VEHICLE, AN AUTO SERVICE FACILITY DISCOVERED SERIOUS FRAME CORROSION WHICH COULD PROVE TO BE A SAFETY ISSUE. THE CORROSION SEEMS EXCESSIVE AND SUGGESTS DESIGN AND/OR MATERIAL DEFICIENCIES. I HAVE HAD TO REPLACE ALL BRAKE LINES AND HAVE HAD TRANSMISSION SHIFT LINKAGE FAILURE, ALL DUE TO RUST. ALSO, EXCESSIVE BODY RUST IN THE LOWER ROCKER PANELS HAS OCCURRED, MORE OF A COSMETIC PROBLEM, BUT INDICATIVE OF THE PERVASIVE RUST PROBLEM THAT EXISTS. *TR

ON FEBRUARY 15, 2012 AT APPROXIMATELY 11:00AM, DRIVING DOWN A TWO LANE PAVED HIGHWAY, THE CROSS PIN IN THE REAR DIFFERENTIAL GEAR HOUSING FAILED AND PARTS OF IT FELL INTO THE GEARS CAUSING THE REAR TIRES TO LOCK UP AND THE VEHICLE TO SKID OUT OF CONTROL INTO THE ONCOMING TRAFFIC LANE. LUCKILY, ONCOMING TRAFFIC WAS ABLE TO STOP IN TIME AVOIDING AN ACCIDENT. THIS WAS VERIFIED BY AMERICAN COLLISION IN RUTLAND, VT AS THE CAUSE OF THE FAILURE.
