Car accelerated without pushing gas pedal
While in bumper to bumper traffic on a one lane road, I noticed the car doesn't stop accelerating even when I fully stop and have to press brake pedal so firmly to keep the car from moving. The engine kept making acceleration noise constantly. I first started changing driving mode from Eco to comfort and sport but didn't matter and only made the rev higher with the mode. I put the car in neutral but no help. I then turned off the engine and turned back one still same issue. Problem was I was in a backed up road so couldn't accelerate at all myself as the car already accelerated by itself. Finally after 5mins or so scary situation at a full stop auto on/off turned off the engine and when it came back on it was all good.
I wonder if you guys experienced something similar? Since my software about a month ago (I'm on one of early 7/2019.xx versions) I had noticed on eco mode while its cruising, time to time the car goes by itself but it was scary in bumper to bumper traffic and I had no way of resetting it. I suspect its a bug/hung state in Software related to acceleration so may take it to the dealer for a software upgrade. Its one of those things thats so hard to replicate to show to the dealership. I should add no driver assist mode (cruise etc) was enabled |

In assisted cruise etc, it should accelerate if there's nothing in front, and you are not braking, but braking should cancel the cruise and leave you in control...
ONE thing to watch out for is that assited cruise might try to accelerate in a corner, or a roundabout if there's nobody in front, or it 'loses track' of someone in front (on the other side of a roundabout)...

Is there a phone line or email? I can go to dealer Monday but not sure they'll do much besides software update. BMW NA might be better route if they can analyze data and see what happened at that time.

mattsrs, if this was truly a scary experience that you felt you had zero control over, I would also report it to NHTSA - you can do so here.. .. https://www-odi.nhtsa.dot.gov/VehicleComplaint/

I think you should call the dealer first. Almost for sure, the dealer will need to look at it so see what is going on. My guess is that if you call BMW NA they will ask if you have gone to a dealer to have it looked at.
What do you expect BMW NA to do? They aren't going to fix it. NHSTA isn't going to fix it either. If BMW NA thinks it is a safety issue they are going to tell you to not drive the car and call a dealer or customer support to get it towed to a dealer to be checked. After all, you are talking about unexpected behavior from the car while it is moving. If you really feel that your wife would not handle the acceleration issue properly then, yikes, I would call the car unsafe. |
