It could be, you can get clear answer after full computer diagnostic from Chevrolet OBD tool. Check engine light is serious and dont ignore, better get diagnose first than driving.

Idlling low is clear issue of tuning messed up, you need to re tune your car and also check spark plugs. AC not working, seems separate issue altogether. Better show to some AC technician who can check the compressor power is on or off.

Sound like one or more spark plug is faulty for sure.

Brake pads last as per how hard or gently you use them. In my car it hasnt change since last 3 year. It can last from 10k km - 50k km depending on driver foot and braking style. OEM company makes are the best and trust worthy, dont buy any other Tijari non genuine saying performance part and bla bla, after all its BRAKE.

It cud be weak brake booster or rusty or worn out brake pads that are slipping.

If car AC fan isnt working even AC s off, this can happen as AC fan has two functions: Must switch on while AC is on and Second function is it shud switch on while car is overheating. In summer now car is more prone to overheating at idle. If AC fan and engine fan is fine, then do the manual check to see if water temperature sending sensor is fine or not. When car overheat step out and open hood and press both the radiator hoses (thick black ones). If its hot as hell and hard as metal that means car is actually overheating and have enough pressure build up inside to make those hoses so hard. If you can press those hoses by hand atleast 25% or more of their size then for sure its water temperature sensor is faulty and sleepy. If one hose is hot and hard and other one is soft and warm then your thermostat isnt opening in time and you need to change that first..
