20240610POWER TRAIN

Less than 33,000 miles the transmission thermostat cause the transmission to overheat. The dealership replaced thermostat and fluids. Then less than 100,000 miles same scenario and transmission goes out. Before it went out it had hard shifting and the obvious shutter at low speeds. Into my second transmission and same thing again!

20231002ENGINE

Since I purchase my 18 Silverado the transmission has ALWAYS had a shift lag. On interstate especially it has become dangerous. I’ve almost been rear ended a few times bc it won’t shift properly. Even with the proper lane change habits the lag and uneven shifting has almost got me killed. Early on when I got my truck (est 2019) a dealer replaced some of the lifters in my engine. I spent over $40k and have even had to replace stereo because it died. I’m disabled I can’t afford to have major repairs while still making payments. Someone needs to hold Chevrolet responsible. I’ve read enough comments from people who have one and their complaints are the same. Is anyone looking into this?

20231002ELECTRICAL SYSTEM

Since purchasing the vehicle in April of 2021, there have been significant issues with the audio system. This was noticed before the first payment was ever made. We had a “Act of God” claim made on the car for a tree falling on the windshield around this time. It was mentioned to the collision center at the time, but it was dismissed. The display will not work, gps system fails, it continuously changes settings and functions, etc. I can see where you would not consider this a safety issue, but I can argue otherwise and effectively, and would be happy to do so. This is a manufacturer issue. I have been made aware by several aftermarket companies that they have had to replace many of these components for similar issues, the dealership where we bought our vehicle literally told me that if I replaced it factory brand that I would have the same issue later down the road, and many acquaintances that have had to replace their audio systems for once again similar issues. This is just in on
