At the risk of outing myself as delusional, I just joined the sudden acceleration club. Never quite believed the stories, but I'm not so sure now.
So I had a few incidents recently, nothing major and no accidents, but startling. Had the last one today. What happens is that the car lurches forward as I start to brake after coasting to a light in traffic. Happened in the rain a few times and I thought maybe I hit a slick patch or something, but today it was dry and it happened again. Each time just after coasting right as I ease into the brake. Sped up for just an instant, but I stopped it each time by screaming and braking harder. And I am certain that my foot was on the brake the whole time or I have already lost my marbles and you can stop reading now.
Have an appointment scheduled to give the mechanic a chuckle, but I also have a theory under my tinfoil hat. I think this might be to do with the regerative brake. I suspect that while coasting on regen, once in a blue moon, the brake pedal somehow disengages the regen before the brakes kick in, so after decelerating on regen, the car tries to jump back to that sweet spot where it coasts like an ICE car. It definitely speeds *up* before the scream braking, like its assuming the accelerator must be pressed to have disengaged both brakes.
So I punch the brake harder and it works, I never assume I on the wrong pedal. But I also want to believe that outside of AP, nothing should make it accelerate but the accelerator, so that leaves me with an issue with the regen/brake transition or a very selective kind of psychosis.
Don't know if or how this relates to other reports, but I am hoping to get it settled soon. Can't imagine not driving my car. I am obligated to profess my love for family, but that S is the best thing that isn't married or related to me.
