Are you releasing your brake as your pressing the park button? I know if I let go too fast it moves forward a bit. As long as I have brake pressed throughout, no problem.

I always press the brake then put in park whether it's on a hill or not. I thought it jumped forward cause I was on a decline but it did the same thing when I was on level ground.

Yes, that is normal. The 7 is anxious to do more driving after it is parked

That "jump" is the car locking into the transmission. It should do it on level ground or any decline/incline.

My understanding is the parking brake works on all 4 wheels when the engine is running, and when you shut the ignition off, only the rear brakes are held, so if there is any loading on the suspension, then when the front brakes are released, a small movement may occur.

The car should not be jumping forward in any way whether you are on an incline or flat. At most you should feel some slight movement when the parking brake is applied and you take your foot of the brake as the suspension relaxes.

The fact that you are feeling something different that you didnt experience before means that something is wrong. Does the car jump forward when coming to a stop with the engine on? or does it only happen after you are parked and you turn off the car and release the brake.

Same symptom here. I am thinking maybe it is something with the control arm bushings.

I've never had this issue and mine was a problematic 7. No, it's not normal.

do you always engage your parkinig brake? try stopping, then with foot brake on, but still in drive, engage the parking brake, then put in park, release foot brake, and then stop engine, usually about 2-3 seaconds after engine stops, the car will move, sometimes almost imperceptibly, other times quite obvious. Hoping this is normal, but maybe there is something up.??

That's a weird coincidence because mine does not do this. Maybe both of your cars had the same issue or you are doing something weird when shutting the card down. The car shouldn't be jumping.

This is a "common" problem with BMW, but that doesn't mean it's "normal". Just like many other "common" problems our 7's have that aren't normal.

Anyone who has this issue and thinks it is or was told by dealer it is normal are in denial. A car, especially of this status, should not "jerk" or "move" suddenly forward when turning the car off. That's just ridiulous. If you happen to park close to a wall or a car in front of you then that sudden jerk might just smash your 7's front. Have it looked over by a good Indy or the Sdealer. I remember when my car was having jerking reactions in low gear I was told by Toronto dealer that it was "normal" - what a douche*!

My car does the same exact thing. It moves about 2" after I completely shut down (Put in P, Parking brake on, shut engine down). Slight jerk. Dont know?! Mine has always done that. No other transmission issues to report. Just emissions right now...

If you guys want to convince yourself that this is normal because it is a common problem then by all means go ahead. I didnt know that I had an issue with my logic 7 amp until I heard one that worked right because most of them out there are broken.

Also seems like people are decribing different things. It is normal for the car to move slightly when the suspension relaxes but not lurch forward in any way. Most people out there with older 7 maybe have issues with the driveshaft flex disk or other components with the suspension with worn bushing extra that can cause things like this.

My car doesn't 'lurch' forward, and its probably never more than a 1/2 inch, but it does move. I'll mention it to the stealer next time it is in.

Sorry to bring up an old thread but I was told when you apply the parking brake while the car is ON it applies with brake fluid like normal brakes. When you shut the car off and get that jerk it's because it is engaging the mechanical parking break and releasing the "actual brakes".

Correct. When the engine is running the hydraulic system activates all 4 brakes as if you are sitting with your foot on the brake. When you shut the engine off the hydraulics stop working and the mechanical park brake grips only the rear brakes. You will get a slight 'kick' as the park brake takes over.
