2017 Chevrolet Silverado 2500

When transiting between airport and home in very remote area in subzero temps the DEF warning system suddenly came on limiting vehicle speed progressively. No services were available both at this time of day and in this very remote area. There needs to be some way to override this system in the case of potential life and death. There were no warnings that this system was going to activate, it simply came on. The system had plenty of fluid but it appears the DEF heater failed. A vehicle should have an override for life and safety matters. Vehicle is going to a diesel mechanic for service now.

At about 62,000 miles the vehicle check engine light came on with codes P0700 and P0741, the RPMs go up as you accelerate but will not shift unless you let off the gas pedal. Reaching 5-6000 RPMs. Had mechanic drop transmission pan no metal found. Reading several TSBs on this issue the transmission should be recalled. Also when towing camper there was some electrical issues when the trailer was contacted the truck would not recognize trailer connected, had to shut the truck off for few minutes and restart to recognize the connection. Truck also lost power when trailer was connected and ran very sluggish, also experienced the shifting issues.

I WAS STOPPED AT A STOPLIGHT, WHEN THE LIGHT TURNED GREEN, I LET OFF THE BRAKE AND THE TRUCK TOOK OFF AT FULL THROTTLE. I NEVER EVEN HAD TIME TO TOUCH THE GAS PEDAL, IT WENT FROM 0 TO 60 IN LESS THAN 1/2 A BLOCK. I THOUGHT IT MAY HAVE BEEN A CRUISE CONTROL ISSUE AND TRIED SEVERAL TIMES TO TURN IT OFF, BUT DIDN'T SLOW DOWN ONE BIT. WHEN WE GOT OUT OF TOWN, I LET OFF THE BRAKES AND IT CONTINUED TO GAIN SPEED UNTIL WE HIT 75 MPH. I AGAIN ENGAGED THE BRAKES, TURNED A CORNER TO GET OFF THE ROAD, AND WHEN I TURNED, THE TRUCK WENT BACK TO NORMAL. IT WAS LIKE A SWITCH WAS TURNED OFF. THE ENTIRE INCIDENT LASTED ABOUT 5 MINUTES, BUT IF WE HAD SNOW OR ICE ON THE ROAD AS IS USUAL THIS TIME OF YEAR, IT SURELY WOULD HAVE RESULTED IN A SERIOUS ACCIDENT.

II TOOK MY 2017 1500 SILVERADO I PURCHASED 11/2020 THAT HAD ABOUT 9500 MILES TO THE CHEVY SERVICE CENTER AND STATED WHILE DRIVING MY VEHICLE WHEN COMING TO A STOP DURING THE 2-1 DOWNSHIFTING OF THE TRANSMISSION A VERY LOUD CLUNKING NOISE AND AT THE SAME TIME IT FEELS LIKE SOMETHING HIT THE REAR OF THE VEHICLE. UPON STARTING FROM A STOP SIGN OR STOP LIGHT THE 1-2 SHIFTING OF THE TRANSMISSION MAKES THE SAME LOUD CLUCKING NOISE AND IT FEELS LIKE SOMETHING HIT THE VEHICLE WAS IN THE REAR AGAIN. THE CHEVY SERVICE PERSON STATED THAT IN THE VEHICLES HISTORY, THE PRIOR OWNER HAD THE FACTORY UPDATE AND REPROGRAM THE TRANSMISSION TO TRY TO CORRECT MY CURRENT ISSUES. I THEN LEFT THE DEALERSHIP WITH THE SAME ISSUES PRIOR TO MY VISIT. ON 7/21/2020 I WAS HAVING MY VEHICLE SERVICED FOR A FACTORY RECALL FOR THE REAR WIDOW DEFROST. I STATED AGAIN TO THE CHEVY SERVICE ABOUT MY CONTINUED TRANSMISSION DRIVELINE CLUNKING ISSUES. ACCORDING TO MY SERVICE PAPERWORK THE SEVICE TECH STATED THE TRANSMISSION IS OPERATING AS NORMAL, BUT ATTACHED TO MY SERVICE PAPERWORK STATING BULLETIN #PIT5161G NORMAL CHARACTERISTIC-BUMP FEEL OR CLUNK NOISE AFTER A STOP {AFFECTING GMC CHEVY YEARS 2007-2020 AND ALSO UP DATED # BULLETIN #99-04-002K INFORMATION ON DRIVELINE CLUNK {OCT 29 2019}. TO DATE 9/17/2020 I AM STILL HAVING THE SAME DRIVING ISSUES.

RIGHT REAR WHEEL HUB NUT BACKED OFF DAMAGING HOUSING SPINDLE THREADS AND SLIGHTLY BENDING THE HOUSING. GM WILL NOT REPLACE HOUSING EVEN THOUGH IT APPEARS THAT A CRACK IS FORMING WHERE IT WAS STRESSED.THERE IS A RECALL FOR THIS PROBLEM BUT MY TRUCK IS NOT INVOLVED. GM WILL NOT CHECK THE LEFT SIDE LIKE THE RECALL SAYS SHOULD BE DONE ALSO.I BELIEVE THAT THERE IS A CRACK STARTING TO FORM AND COULD BE A PROBLEM WHILE DRIVING IN THE FUTURE.

TRANSMISSION SHIFTS EXTREMELY HARD CAUSING A LOUD CLUNK AND THE VEHICLE TO LUNGE FORWARD. THIS IS EXPERIENCED A LOT DURING SLOWING DOWN AT YIELD SIGNS OR WHEN STARTING OUT IN TRAFFIC. THE TRUCK EXPERIENCE A SPLIT SECOND DELAY IN ACCELERATION AND THEN SUDDENLY SHIFTS VERY HARD LUNGING FORWARD. GM MOTORS DEALERSHIP ACKNOWLEDGES THERE IS AN ISSUE, BUT THEY DON'T HAVE A SOLUTION AND GM ENGINEERS ARE HAVING THEM TELL THE CONSUMERS THE TRANSMISSION IS OPERATING AS DESIGNED DESPITE THEIR OWN SERVICE TECHS AND SERVICE MANAGERS AND DISTRICT MANAGERS STATING THERE IS A PROBLEM. AFTER 3 DIFFERENT ATTEMPTS TO GET THIS RESOLVED I FILED A COMPLIANT WITH GM CASE # 8-3228178744 THAT REMAINS UNRESOLVED AS OF TODAY. THERE ARE THOUSANDS OF GM 8-SPEED TRANSMISSION OWNERS HIGHLY UPSET OVER THIS AS MANY IF NOT ALL ESCALADE, CORVETTE AND TRUCK OWNERS HAVE THIS ISSUE. A MANDATORY RECALL IS IN ORDER. IN MY OPINION THIS IS CLEARLY A SAFETY ISSUE THAT SHOULD BE ADDRESSED BEFORE SOMEONE IS SERIOUSLY INJURED.
