2015 Chevy Silverado, 62,300 miles. While driving at highway speeds. The air condition compessor locked up. Causing the engine to die and causing the loss of power steering and power brakes.

I have contacted the dealer and they say there is no recall.

- Mabelvale, Ar, AR, USA

I am having issues with my transmission. When I first turn on the truck in the morning, put it in gear, and lightly accelerate the truck accelerates way too fast then cuts out the power. It is enough to throw me forward or back in my seat and it honestly is frightening. I am also having problems with the vehicle shifting incorrectly causing me to have no power or a sudden surge of power. This is usually when i have slowed down and them am trying to accelerate again. Also, When I am slowing down to stoplights, the vehicle will occasionally shift down to too low of a gear and act like i am slamming on the brakes. I have had several close calls with this truck due to this issue. Gm knows about the issue and has refused to recall the vehicles that are having these problems. They are recommending changing out the fluid multiple times at the owners costs. This has resulted in several class action lawsuits. They also have gone to the lengths of changing warranty coverage to no longer include abnormal shifting. This is not safe. This is causing accidents and they are actively covering it up. Please help the hundreds of thousands of people that are having issues. We need your help, I need your help and gm is no longer standing behind their vehicles.

steering and braking stops working during low speed. AC stops working and several components flash a warning message Trailer hitch and stabilizer and engine light appears sporadically. It shows that I do not have recalls but I believe the repairs in the past were not done correctly. old software or a electrical short from an faulty part!!!!!

- Chandler , AZ, USA

Currently, the AC is no functioning properly. Mechanic states that the hose leading to the compressor that's mounted towards the radiator is cracked and he can see oil from the AC system that has leaked out over time. Parts are being ordered to replace and repair so that the AC system will work properly. Improper AC function is not acceptable during the spring/summer months, and AC is needed to be able to cool the vehicle down There were no warning lamps or messages. We determined the system was low on coolant because it was not cooling properly.
