New X3? Don't open your door!
I learned something new about my new 2013 X3 today. If you open your door with the car in drive or reverse, it will automatically pop into Park. I've read about half the owner's manual and haven't seen any reference to this. Maybe I'll find this note if I keep reading.
Obviously the concern is that this could cause real damage to a transmission if the car is moving at all.
I had my windows tinted yesterday and am not suppose to open them for three days. So today when I went to work, I remembered I could not lower the window to use my garage access key. I pull up to the card reader and fortunately stopped before opening the door to slide the key out with the door cracked. When I did, and let my foot off the brake, the transmission immediately popped into "Park". So I had to close the door, pull forward until I was in the exact position needed, then open the door.
When I got home, I tested this a couple times and sure enough this "too smart for it's own good" car pops into park if the door is open. I've only tested the drivers side, not the passenger side or any other door. But what immediately came to mind is what if someone is moving when they decide to dump a cup of water out, or what if a passenger does the same thing.
Bottom line is if this happens while the SUV is in motion, you could be looking at real transmission damage. I thought I'd better post this warning. Perhaps some of you can see if your car does the same thing. Obviously try this with the car stopped and slowly let off the brake.
