I have a 21 Mazda CX-5 Grand Touring Reserve. When I have the A/C on and sitting at a stoplight the engine increases RPM when the compressor engages. If you don’t have your foot on the brake pedal hard enough it will make a slight surge forward when the RPMS increase. My car has the Turbo. I am light on the brake when a stoplights I guess because if you aren’t light on the brake I bet you wouldn’t even notice this.
