The current recall for the defective transmission valve does not address the safety issue with the vehicle. This a known issue with the truck and the transmission valve should be replaced rather than simply monitoring it. My safety and the vehicles I share the road may be at risk if the software upgrade limits the drivability while pulling a trailer on interstate highways. The life span of this vehicle is well beyond the allotted 150,000 miles of coverage and to not extend this "special coverage" beyond the original owner makes this a safety hazard to future owners of the vehicle as wellupgrade .GM is calling the software a "service correction" when in reality they are making no correction, just monitoring the problem.

In certain GMC and Chevrolet Models 2019 to 2025 it is common knowledge and easily found on the web that there is a manufacturer defect that does not allow the vehicle to be placed in “park” properly due to defective parts in the steering column that do not allow the vehicle to safely turn off fully. The module does not seat and the vehicle will remain on in auxiliary. https://m.youtube.com/watch?v=RTcX-j3R5OQ . Again the link is an example but this defect is rampant.

Originally Chevrolet offered a 2 phase approach for this recall. First phase was to install monitoring software in the ECU and TCU to monitor for early transmission control valve premature wear. Second phase was to actually replace the suspect valve. I've just received a second correspondence from Chevrolet for this recall, now only offering Phase 1, TCU and ECU monitoring software installation. So if the monitoring software detects premature valve failure, the vehicle will be limited to 5th gear. I don't think limiting a vehicle to 5 our of 10 gears is a safe solution. If I'm on the freeway, towing 10,000 lbs, and my vehicle is limited to 5th gear, I may have to travel a very long time at way below posted speed limits before I can get to a dealer for repair. As we all know, travelling on the freeway at lower than posted speed limits can be just as dangerous as travelling above posted speed limits. And in fact, here in Idaho, if you're travelling below posted speed limits you can be fined just as if you were exceeding speed limits. I feel Chevrolet's original solution is the best. Replace the suspect valve proactively instead of actually waiting for it to fail which can possibly cause an unsafe condition.

Engine Code P10D9. Electrical harness to the DEF tank melted. My truck was not part of the GM recall but clearly effects more vehicles than they believe. See NHTSA report N212342980. Spoke with Chevy customer service today and they stated the wiring harness melting is not covered under warranty. This is a fire hazard that GM should remedy. The recall is clearly larger than 38,000 vehicles. Are we supposed to drive the vehicles and not know if they will catch fire or not? I spoke with a technician at Milnes Chevy in Imlay city today and he stated that he sees so many of these trucks that were not under the recall having the same issue with melted wiring harness.

The DEF heater short circuit and derates the truck. If the government says we have to have this they should cover the cost to fix it.
