While we're on this topic, here's a bit of off-topic info regarding the transmission that I've discovered on my own:

To test the vehicle's safety, due to the recent "run-away" Toyotas that refused to turn off, I conducted a test in a parking lot.

I wanted to make sure that if the vehicle accelerated in an uncommanded manner, I'd be able to shut the vehicle off.

In doing so, you can turn the vehicle off at speed by pressing the "start" button. This will shut the vehicle off.

You can also switch the vehicle into neutral, but after a few feet of neutral it will automatically shift into park.

The best bet, if your BMW ever accelerates on its own is to press the start button, slam on the brakes, and disengage the key (if you don't have comfort access) Next, I'd try switching the vehicle into neutral, and lastly I'd try park.

The Toyota issues are due to floormats becoming jammed into accelerator pedals. But, with drive by wire technology, anything is possible.

So, if you have some time, I'd recommend becoming familiar with how to perform an emergency shutdown of your vehicle.

This is my over cautious pilot background coming into play, but nonetheless, I think it's wise to know how to instantly prepare for an eventuality, given the electronic complexity of our vehicles.

One thing I want to caution against in a VERY CLEAR MANNER: if you pull the key out of the ignition and you do not have comfort access, be aware your STEERING COULD LOCK! ONLY pull the key out as a last ditch effort. It's far safer to total your X5 at 50 miles per hours, than it is at 120 miles per hour, under full acceleration. Worse yet, imagine an uncommanded acceleration on a downhill curvy road. You'll have seconds to respond, so please do yourself a favor and experiment on your own to become familiar with shutting down your X5 in the event of a malfunction.

Although it's highly unlikely to occur, it's possible nonetheless.
