Mein Auto: 2007 328i Sports Wagon
Unintended acceleration

Last Saturday, 7 September 2013 I slowly drove up to a parking place at the Sullivan's Island, SC Post Office. Without reason my 328i Sports wagon accelerated at a high rate of speed causing it to go over a 10inch sidewalk and into a low area beside the Post Office. I hit a Post Office sign and brushed against the brick Post Office building. While there was no damage to the building and the sign, there was considerable damage to my vehicle. I had it towed to the Charleston Rick Hendrick dealership where I purchased it new in 2007. The estimate so far is a little over $ 7,300.00,and I am now waiting on the mechanical report.
Until reading about others who have had the same experience I tried to think through what happed and what I may have done wrong, but nothing made sense.
Thank goodness no one was injured and the only damage was to my vehicle. Had I pulled up to the front of the building it could have been a disaster.
I have enjoyed owning and driving my 328i, but I can no longer be assured that this will not happen again without some resolution as to why this occurred.

Before you all jump to Lexus you should do your homework as they have had the same issue with a 1.1 billion dollar payout affecting model years up to 2010. No guaranties on any brand.

And you, pushing on the brake pedal as hard as your adrenelin charged muscles could, were unable to immediatley slow or stop your car?
Simultaneous failure of two totally separate systems. Interesting.

yes, VERY interesting how a strong application of cool brakes was unable to stop the car from running into a wall with such a short distance for it to accelerate.



The DOT hoped to answer this and other questions about these suspect Toyotas. In most cases, the driver reported that the sudden acceleration began immediately after the driver applied the brakes. DOT engineers determined that there was no mechanism by ***8201;which applying the brakes could initiate acceleration. Additionally, they conducted tests to determine that, at low speed using normal pedal effort, the brakes could easily hold a car stationary or bring one to a stop even with the engine racing.

A field examination of 58 vehicles said to be involved in unintended-acceleration crashes revealed no evidence of ***8201;brake failure or throttle malfunction. Moreover, these Toyotas were equipped with simple event data recorders (EDRs, or "black boxes***8221, as about 85 percent of new cars are. Of the 39 vehicles that fit the unintended-acceleration pattern and had usable EDR data, none showed sustained, pre-crash braking taking place and 35 revealed high or increasing accelerator position.
Finally, to evaluate the possibility that some sort of electronic gremlin caused these problems, the DOT engaged the rocket scientists at NASA to probe the Camry's engine-management computer, comb through its thousands of lines of code, and bombard the system with high levels of electromagnetic interference.

NASA scientists evaluated six Camrys (ranging from '02 to '07 models) the DOT had purchased from customers who reported sudden-acceleration problems. The scientists found that the electronic throttle-control (ETC) system had several fail-safe features designed to cut engine power if any ***8201;failure was detected. The agency also found no circumstances under which the ETC could somehow disable the braking system.

To test for electromagnetic interference, NASA subjected the six test cars to very high-powered radiation at a variety of frequencies. The agency also directly ***8201;imposed these electrical signals into the cars' wiring harnesses. In the process, the NASA scientists stalled engines, induced limp-home mode, and even entirely fried one engine-management computer. But they ***8201;were unable to cause a single instance of sudden acceleration.

Based on the DOT report, it seems clear that the Toyota sudden-acceleration scare has little more substance than the one that came before it [see below]. Ultimately, driver error was the culprit.

Good questions since brakes can hold a high HP drag car on the starting line while the tach bumps off the red line.

My $0.02.
I see both points of view being expressed here.

On the one hand, yes the unintended acceleration events (let's call them UAEs) should have and probably were stoppable by some combination of driver emergency maneuvers (parking brakes, mashing the brake pedal, putting the car in N or P, etc.).
On the other hand, this is getting dangerously close to Blaming The Victim.

No no no, DSX - unintended acceleration is a serious issue and has now been documented - BMW operating systems are compromised, possibly w/viral infection. Vehicle electronic communication & tracking as BMW has implemented is vulnerable to cyber warfare and control from religious and rogue states, even our own NSA!

And while I do wonder how a 3 went over, instead of into, a 10" curb, the enormity of the situation cannot be ignored.

Clearly [as you point out], brake assist failed as well. Coincidence? I think not! Classic strategy - a pattern of disablement, overwhelmingly so, instantly creates despair and remorse. It is unfortunate that unassisted braking seemed not to work at all....isn't that what shock and awe is all about?

Masterful! OP was controlled completely, to his cost. If you ask me, smacks of a govt psyop, but hey, who are we?

Has anyone here considered that none of this emergency full braking should have been necessary in the first place?
It's like: "My car caught on fire and all my stuff inside burned up!" "Well, you should have had an emergency fire equipment retrieval plan in place, you retard." Ignoring the fact that the car shouldn't have caught fire in the first place....

Of course I could be way out of line here....

Stuff happens. Had unintended acceleration in a '67 BB Corvette when the throttle return spring broke on the dual 4 barrel carbs at WOT in 3rd gear at Englishtown Raceway Park. No high tech in the car just a hard part failed that should not fail.

Full pressure on the manual brakes, ignition off, engine did not stop right away as it went into diesel mode but the car still came to a stop.

unintended Acceleration

Some of you have implied that I should have been able to stop the vehicle which in fact I did after it jumped the 10 inch high curb and traveled 10 feet past the sidewalk. I was able in those very few seconds to avoid hitting the building or sign head on, and stop. Given that the totally unexpected acceleration happened when coming to a slow stop, and my wife will testify to this , I performed exceedingly well.
This is a serious fault and it was NOT mine.

Sorry if we are skeptical but nearly every issue of unintended acceleration has proven to be operator error. I suppose it could be some software glitch but otherwise the only way more air and fuel can get into an engine to make it accelerate is to push the throttle.

Sorry, after the Toyota and Audi "unintended acceleration" circuses, I don't think anybody will believe you. Did you ask the dealer/BMW to investigate? The car has a black box, after all. These cars all have the same software. How could a couple of cars per year self-accelerate, out of hundreds of thousands made?

you were slowing down... you had your foot on the brake?

next time you are slowly driving, put your left foot on the brake and right foot on the accelerator. press both as hard as you can. wait and see what happens.

I hardly believe my eyes....are you guys serious?

I mean, really....a 10" curb. Half the height of a wheel. Hit a sign and a building, but no damage to either....major damage to the car.

Yo! For those who feel pain, perhaps you'd like to contribute to my fund for the fight against Global Warming? Please PM!!!!!!!!!!!

It is unfortunate these things happen and perhaps it did happen in your case, but I have never heard a concise explanation as to how this could happen - mechanically. Stuck accelerator peddle, maybe an electronic failure for the drive-by-wire systems? When I was younger I remember the Audi sudden acceleration scandal and no one could replicate it when asked. I doesn't mean it can't happen...drivers sometimes get confused and give it gas when they shouldn't.

If you have ever been to racing driving school as a younger person and been at skid pad, braking and turn instruction, instructors sitting beside you sometimes squeeze your leg HARD, when you are accelerating when you should be braking. Every driver swears he was braking but then they end up in the ditch. It happens. Not suggesting it happened to you OP, but i happens. The sudden acceleration phenomenon has made changes to the way cars start, engaging the brake peddle before engaging the starter for instance.

I do think cars can rev highly when started after sitting cold for instance, and some are programmed to do just that of course, and sometimes there are surges - caused by damaged fuel filters and spark plugs. So that does occur. But "sudden acceleration"? Demonic possession? PTRC is right, there are diagnostics that can tell BMW what might have happened. Check it out.

Just to replay it in your mind...you approach a parking spot and then the car accelerates so hard it "jumps" the parking curb (I think) and heads down a hill BEFORE you can hit the brakes? Where was your foot?

The car stops. Before line locks & trans brakes were invented all serious AT drag cars where held on the line under power with their brakes.

No offence intended to the OP because stuff does happen & he was there we weren't. I have some issues with the description but systems can & do fail. Its a good discussion because if it happens to anyone the first action should be to brake hard, steer to avoid & get into neutral. Pretty much all at the same time. Once stopped kill the ignition.

It is a good discussion. Has anyone had a concise explanation of how it could happen? I agree that braking power outperforms engine power all things being equal. So how does a car accelerate so hard from just being nursed along, and in most cases getting ready to stop?
