So wife's new GMC has the engine stop/start technology that shuts off the engine at stoplights, etc., based on a number of variables that the ECU takes into consideration moment to moment while you're sitting there. On her GMC at least, it figures in brake pedal pressure that you're applying w/ foot. If you apply the lightest of pressure to just stop the car from creeping forward, it will leave the engine running. Just a hair more brake pedal pressure however and it will turn off the engine.
Here's one rather arcane side effect of the engine stop/start thing: When you are parking the car, as you pull up and stop with normal pressure on the brake pedal, it will shut the motor off while still in D (transmission selector), *then* when you shift it into P (park) it will start the engine. So you pull into your garage, brake to stop and off goes the engine, but when you want to place it into park it starts the engine back up, only to have you shut it down again. Seems rather dumb to me.
GMC does not let you disable stop/start feature. It doesn't really bother me, but the part where it stops the engine in D as you go to park the car then restarts it at the instant you engage Park (P), that's kind of stupid I think.
