2020 3.0 diesel duramax sucked in the antifreeze and caused a hydrolock. The dealer says that it is not covered under warranty since the engine was over 100k miles. They did offer a new engine for $30K which I declined. The truck was always well taken care of and only received the best in all products

ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM02/12/2026
On approximately January 24, 2026 my 2020 Chevrolet Silverado 2500HD equipped with the 6.6 Duramax Diesel displayed an error code (P20B9). This error code was found to be related to the diesel exhaust fluid system specifically relating to "Reductant Heater A Control Circuit/Open." On January 27, 2026, the vehicle was diagnosed at Chevrolet dealership and the following was reported "Diesel Emissions Fluid Tank Remove and Replace - P20B9 SET FOR REDUCTANT HEATER CIRCUIT...COMMANDED ON AND ZERO AMPS..CIRCUITFAILURE... DISCONNECT PUMP MODULE AND BURNED/OVERHEATED TERMINALS..PUMP MODULE AND HARNESS PART OF TANK ASSEMBLY... LABOR TIME ADDED TO PERFORM MALFUNCTION/TAMPER TEST TO CLEAR EMISSIONS MESSAGE...." I found the "burned/overheated terminals" comment to be alarming. I looked into this matter further and found a GM Service Bulletin (21-NA-006) from October 2022. This bulletin identified this issue which contained an image showing burned/overheated terminals. The identified cause within the bulletin states "This condition may be caused by a poor connection at the Emission Reduction Fluid Tank electrical connector." I believe this should upgraded to a safety recall due the the potential of this terminal connection catching fire which could be detrimental for the operator, passengers, property, and the public.

10L1000 transmission, began having problems with delays and harsh gear engagement. Flare shifting and shuddering. Finally starting having transmission overheating issues while towing. I had to make several unsafe stops with a trailer to wait for the transmission to cool down again before continuing to get it home. Saw trans temps up to 240°F on flat land with 40° outside temps. I could smell the hot transmission fluid inside the truck. When I went to check the fluid level of the transmission, the fluid was full but had a large amount of glitter like metallic flakes. The fluid was very dark brown in color and smelled terribly burnt. The last recall I took in to the dealer for was about the transmissions possibility of failing, locking up, along with the rear wheels at any speed. I have young children that ride in this truck, that in it self was unsettling and unsafe. But then to have issues with absolutely no warning light was concerning. Ive since ordered an aftermarket built transmission to avoid repeating the same issues with a factory GM replacement. My factory warranty had also ended a few months prior to having these problems with it. Leaving me to completely foot the bill for it to be replaced. I had to pull money from my retirement early to cover costs, in fact costing me much more than just the sticker price.
