In December 2024, I brought my vehicle in for the rear end lock up recall.  The recall reprogrammed the transmission control module.  As admitted, by yourself and GM this doesn't fix the problem.

Also, it is replacing it with the same valve body, i.e. you will have the same problem in the future.  Nextgen Drivetrain has a valve body for around $1000 that fixes the problem.  [XXX]  .

While traveling 60 mph pulling a fifth wheel in South Texas on a clear and dry day, the rear passenger tire unexpectedly lost its tread.  As we slowed down, it completely lost tire pressure and we ran on the rim until coming to a complete stop.  Immediately prior to the incident, the TPMS and other safety systems in the truck read normal.  There were no system warnings and no objects in the road.    It put us in a dangerous situation as we were stopped on the shoulder of the highway right before a bridge and had our 3 children in the backseat.  We called the police, but they never sent anyone to help with traffic.  The rear fender and the wheel well of the truck were badly damaged.  We have the faulty tire and it is available for inspection.","products":[{"type":"Vehicle","productYear":"2020","productMake":"GMC","productModel":"SIERRA 3500","manufacturer":"General Motors, LLC"},{"type":"Tire","productYear":"9999","productMake":"GOODYEAR","productModel":"WRANGLER TRAIL RUNNER","size":"LT275/65 R20","manufacturer":"Goodyear Tire & Rubber Company"}]},{"odiNumber":11493546,"manufacturer":"General Motors, LLC","crash":false,"fire":true,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"11/13/2022","dateComplaintFiled":"11/14/2022","vin":"1GT49WEY8LF","components":"ELECTRICAL SYSTEM,STRUCTURE,ENGINE","summary":"Plugged in engine block heater and the car erupted in flames.

Our safety was compromised when the design of the HVAC system and the battery location allowed the hydrogen sulfide gas into the passenger compartment of the vehicle.  The issue has not been confirmed by a deal or independent service center.  The battery(s) and vehicle are available for inspection to confirm the issue.  I have uploaded pictures of the battery and one can visually see the swollen battery with liquid leaking out of it.  There were no warning messages or other symptoms prior to the failure.  The rotten egg smell started shortly after the truck was started and my three young children were in the truck for about 10-15 minutes while I was loading items in the bed of the truck.  When I entered the vehicle, the smell was extremely strong and my eyes started burning.  I opened all the windows to air out the passenger compartment and thought it was possible off gassing from the nearby septic field.  Once driving with the windows now closed, the smell came back instantly and very strong.  My children started complaining of headache and nausea.  For the next part of the trip, we drove with the windows down.  When we arrived at our destination, I was able to determine the smell was coming out of the HVAC system while in normal \"Auto\" mode.  Opening the hood, I went to smell around the engine compartment and when I got over the passenger side main battery, the rotten egg smell was so strong that my nose and eyes instantly started burning.  We then drove the truck home with the windows closed and the HVAC system in recirculate but the smell still entered the passenger compartment.  All four of us had symptoms of hydrogen sulfide poisoning with my son being the worse with multiple vomiting episodes immediately upon exiting the vehicle.  Poison Control was notified and all four of us were evaluated in our local Emergency Department for Inhalation Toxin.  The truck is all OEM.","products":[{"type":"Vehicle","productYear":"2020","productMake":"GMC","productModel":"SIERRA 3500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11456331,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"03/04/2022","dateComplaintFiled":"03/11/2022","vin":"1GT49UEYXLF","components":"UNKNOWN OR OTHER","summary":"In short, the Diesel Exhaust Fluid (DEF) reductant heater failed which requires the entire DEF tank assembly (part 85138746) to be replaced on my 2020 GMC Sierra 3500.  This cause the truck to go into \"limp\" mode where it will not travel above 65 mph, and after another period, the speed continues to be reduced down to 25 mph.  Prior to the speed being reduced, there is a warning message that appears stating \"Service DEF System See Owner's Manual\" and a warning light illuminates in the gauge cluster.  Any severe reduction in speed that can cause the truck to go \"limp\" is a safety concern.  In addition to being a safety concern, some quick internet research reveals that this has been a known problem with GM's DEF system since at least 2019.  The electrical connections are too small for the current which supplied the DEF tank heater, causing the system to short and trigger the truck into limp mode which renders it useless.  The replacement part is on national backorder, and it has been on backorder for years.  My truck is completely useless until this part (or a better-engineered replacement) arrives at the dealer, and there are hundreds if not thousands of people waiting on this same, defective part to get their trucks back on the road.  People are losing their livelihood and the means by which they support their families.  GM has known about this defective part for years and has done nothing- neither engineered a better part nor issued a recall with some kind of workaround.  They haven't even been able to stock the defective part, and this is not just a supply chain issue as new trucks are still being built.  This problem was not inspected by any police or insurance agency as it did not cause an accident or injury in this case.","products":[{"type":"Vehicle","productYear":"2020","productMake":"GMC","productModel":"SIERRA 3500","manufacturer":"General Motors, LLC"}]},{"odiNumber":11440826,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"11/03/2021","dateComplaintFiled":"11/17/2021","vin":"1GT49WEY7LF","components":"ELECTRICAL SYSTEM","summary":"Infotainment system AND center instrument cluster went completely black - six times over the course of one month.
