Shuddering & fuel guzzling w/ AC on
2012 Chevy Cruze, 1.4L Turbo, 103k miles.
So, recently my car has been shuddering when I accelerate, delayed shifting, like it feels like it is dragging and seems to shift late and all over the place, and I have noticed excessive fuel consumption. Like, I used almost a quarter of a tank going to work and back. 34 mile round trip on a car that averages 35mpg. Now, the kicker, I recently turned the ac on because it is now 90 every day by me. Please, any suggestions? Transmission, compressor and computer modules are under and extended warranty so I’m not terribly worried but it is still annoying af. Thanks.
If the compressor is going out, it will put a heavy load on the engine. You said this happens with the AC on? I would have the compressor checked for proper operation.
