2020 Chevrolet Silverado 2500 problems

“While driving on the highway our transmission cooling line completely separated at rubber hose to metal line crimp. This cause transmission fluid to burst out all over the vehicle including the windshield and trailer. Vehicle immediately stopped pulling and we barely were able to get to the side of the road. This also caused a catastrophic transmission failure costing approximately 10,000 to repair. GM covered some of the transmission cost but still left us with 5000 bill for a transmission line defect on a vehicle under 100,000 miles. This created a unsafe condition with the trans fluid on the windshield and immediate loss of drive. All maintenance was performed per manufacturers specifications and no warning signs/lights/leaks provided prior to the failure. I do have pictures of the failed transmission cooling line.”

“Trailer brakes keep disconnecting and connecting . Warning pops up on dash to check trailer connections. I may not happen for a hundred miles or does it 10 or 12 times in just a few miles.I've seen several complaints from on line reports but no solutions from GM yet. Very frustrating when trying to pull a trailer.”

“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”
