Increased stopping distance during certain brake vacuum loss events. My check engine light goes on and off periodically. When I-??m at a red light my whole car shuts off and goes into a neutral mode then once I press the brake it starts back up.

The check engine light is always on and has not been diagnosed (as of yet) by Circle Buick - Highland, IN. There is an auto-engine-shutoff feature when the vehicle stops at traffic lights, and when you resume driving there can be a lengthy delay and/or an engine & transmission jolt after the brake pedal is released. The vehicle must be retested every two years for emissions compliance for IN, but cannot do so because of the check engine light never going off. This is a safety issue not to get hit from behind in local traffic. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
