This problem is with the stop start feature on my car which if I knew about it I would have never bought. My husband has hated this car since day one and only bought it as I have stage 4 cancer and fell in love with the car. He wanted a Subaru which he can get once I leave the earth.I now longer am pleased with this car as it will lead to my death sooner than the cancer. When this car stops to save gas ha ha uses more the motor shuts off so the headlights dim. Then when you hit the gas they brighten. Well drivers around here think we are telling them to go as we blinked the lights at them even if you were first there. My husband always gives everyone the right of way but I am not so kind.if first I go first. The other night I almost got it as a truck pulled out at the same time almost hitting me and calling me a few names but telling me I flicked the lights. Looked in the owners manuel and not a thing about this feature so called the garage.took it right away and after 3 days said this is how it was suppose to act. Well if I get hurt from this I will sue GM as every other car maker put in a device to shut this feature off but not Buick..when this happened I was at a 4 way stop and was there first.truck was to the left of me who pulled out at the same time almost getting me on my drivers side. This is a horrible feature and I can see why other car makers have a switch to shut it off. I have never gotten the milage that we were suppose to get. Garage blames it on winter gas but had it for a year now and only got 24 at the most, in the summer.since the cancer we drive to pittsburgh 120 miles once a month and that trip only gets us 23 in summer.did get it to 24 but still feel this car is my death weapon.I feel its a weak battery or a electrical short. On a downtown kittanning pa street.garage just makes us feel stupid for even complaining.
