I just bought a 2007 BMW X3. I test drove a different one, then took the one of the showroom floor in the color I wanted. I did not notice hesitation on test drive, but immediately noticed on mine. It is a week old and I hate it. Not to mention the stupid protruding plastic door handle that my knee constantly hits. The hesitation is horrible. It does it from a dead stop, and while driving at slow speeds. It is unacceptable to me-I want to return it. The transmission is so erratic, that passengers complain about the rough and jolty ride-it is embarrasing to tell them I spent so much on a piece of junk. I think I made a mistake. This is going to be my last BMW. I should have bought the Nissan Murano! BMW had better get this thing fixed or they will face a major class action suit. Also, I have the starting problem that I have seen others talk about. My 10 year old Jeep that I traded in on this started every single time! This thing failed to start 8 times in the first week. You need to hold it and crank the engine for 2 or 3 seconds like the cars from the 50's!

I am taking mine to the dealer in a few weeks. I dont know why I have to wait 3 weeks to do it. I am going to call to reschedule it earlier. I think they are stalling for time. The BMW service advisor is aware of the problem, but is not aware of a fix for it yet. They had better get something together because I will give them 3 attempts, until they are taking it back under PA lemon law. I am very serious about this problem! It is so annoying that I will not be able to stand staying in the 36 month lease! Can you believe that I actually liked the my 10 year old jeep better? It was smoother. I never had a shifting problem with that.

This was just posted on bimmerfest.com: I made an appointment to take mine in next wk.
This problem has been addressed by BMW. Tell the dealer to refer to SIB 24-08-07. This includes a reprogram of the DME and the EGS.

I just had the dealer look at it this week. They reprogrammed it with a new software update from BMW. They said to drive 100 miles or so until evaluating it, but I dont see any change so far in 25 miles. It is still hesitating (although it seems very slightly better), but it is still very rough and erratic in upshifting and downshifting. Also in SD mode, when I let my foot off the gas, it decides to rev to 6000 rpm's briefly and intermittently for no apparent reason. Not happy, but I will see what happens.

Thanks for the link. Never knew about this. My station went from Chevron to Shell recently. Both on the approved list.
Good news for my 545i!

Mike-The update or "fix" does NOT work! And yes, I do use 93 octane. The hesitation has nothing to do with loss of engine power, it is in the computer that controls how the transmission shifts.
You press the gas, and nothing...it goes slowly, then jerks forward. Sure, it might go without hesitation if you "floor" it. This transmission controller works like a 16 year old girl learning "stick" for the first time. It is very jerky on upward and downward shifting.
Everyone makes remarks about it when in the car, like, "how much did you pay for this", and "I thought BMW was good".The other day, I was driving 40 miles an hour, then let off the accelerator, then it shot up to 6000 rpm's briefly, then back down. Never had a car do that before. I do not like this-every day it hesitates!! Okay-I concede that it is a little better. I think this is a temporary software "patch", but not the ultimate fix.
My lowest rated consumer reports 10 year old jeep shifted WAY better.
Mine is going back in again for service!

I really think that the software programmers for the ECU need to soften up on the engine compression braking, or eliminate it. Most people do not like it-not only on the BMW-which has VERY strong compression braking, but others like Toyota as well. I feel like I am going to be lunged through the windshield when I lift my foot from the accelerator at 45 mph. And how can this possibly be good for gas mileage, not to mention the REQUIRED 91 minimum octane. hmmmmm. Makes me wonder if the car companies are in the pockets of the gas companies?
Anyway-they better do something soon, because my car sucks! It is a very frustrating and rough ride.
