Bought equinox with 9 miles o it on monday 05/27/2019 and on friday 5/31/2019 on the way home from going to dinner, with only 213 miles on the vehicle, the check engine light came on and the engine power is reduced warning light came on. looked up the error code on line, because the owner's manual is not that easy. code displayed could shut engine off at any time to prevent further damage. thank god we were a 2 miles from home.
Car would start bucking, stuttering and jerking. this occurred three times. a/c compressor froze, had to be rebuilt. almost got rear ended twice. the dealer could find no problem on the last two times. this happened on city streets while in motion and from a stop.
Auto stop / start is going to get someone killed. hesitation from brake to gas causes a whiplash effect to everyone in the vehicle. also, pulling out in traffic is a total crap shoot as to weather the vehicle is going to start, hesitate or go at all.
The engine "auto stop" feature can have enough of a delay to allow the accelerator to be pressed as the engine starts causing it to lurch forward rather than accelerate smoothly. it also can cause a delay when pulling out into heavy traffic. there is currently no way to temporarily or permanently defeat the system on this gm model according to gm service department. though i am sure it is operating as designed for certain owner driving styles and traffic conditions this can be a serious hazard. car makers should be required to either disable the feature permanently by owner request or have a method for the owner to bypass the system. with less than 250 miles i have experienced 2 incidents of almost hitting the car in front of me from a stop and 1 of almost being hit pulling into heavy traffic from a stop. i see many other similar complaints and hope this can be addressed before someone is hurt or worse due to it. while stopped at a railroad crossing with auto stop the engine unexpectedly started as a/c compressor turned on causing the car to lurch forward toward the moving train. almost a major near death issue.
