All of our vehicles have autostopeliminator installed, even the company vehicles. While I understand the premise, stopping the engine while sitting at a stop light is better fuel economy, or at least that is what they say. They didn't figure in short trips around town of just a few miles everyday. Those short trips with auto stop on, you will find yourself with a dead battery after a day or two. My daughter in-law, drives 3 miles each way to work, drops the kids off at school, there is a stoplight, or stop sign at every corner. They bought a new Suburban, after 3 days of just driving to and from work, dropping the kids off and shuttling them around, she gets in and it won't start. Towed to dealership, they test the battery and electrical, all is good. They give it back to her, no problem found, they just charged the battery. 4 days later, dead battery, she calls AAA this time. AAA comes out, tests the battery, jump it, tell her the battery and charging system are ok, must be a drain somewhere when it is off. She takes it back to the dealership, they can't find anything wrong.
This keeps happening every few days, my son is livid they have a new car that keeps needing jump starts. On one of the AAA jump starts, the tow driver tells her to turn off autostop, short trips, stopping the engine and restarting it, the battery is probably not getting charged enough, he sees it all the time. She turns off autostop everytime she gets in. No more jump starts, problem eliminated. He is now a believer in autostopeliminator.
