After purchasing my 2011 528I I noticed the car would not accelerate smoothly from a stop or after slowing down to make a turn, it actually felt like it was applying the breaks until you applied close to half throttle then it would lurch forward. The car was taken to dealer and received a patch and programming which made no change. To top all of this off it picks and chooses when its going to drive "normal" so you don't know what to expect....this is unsafe...... on the freeway it wont downshift to pass unless pressed to the floor, the motor just lugs and wont give you the expected response causing cars and trucks alike to be cut off because you didn't accelerate as expected.... I cant believe BMW is allowing its flagship model the 5 series to have these issues and not address them.... the car pulled to the right as described by many, I took it to the dealer and left at the end of the day with a $300 alignment"???? I'm concerned with getting stuck with a lemon $50,000 car that I wont be able to sell, atleast offer a buy back program??" help!!!!!

From a complete stop, when accelerating, there is a lag or hesitation before the car takes off. When it does take off, there is a hard jerk. It makes it very hard to gauge the distance between you and other cars when it lunges very quickly. If you're pulling into traffic, as in my case, it can be very dangerous. Also if it's wet, and this happens, it could cause you to lose control of your vehicle. This needs to be investigated, as it can be a major safety issue.

When accelerating from a complete stop or driving at higher speeds (50-80mph), the vehicle consistently pulls to the right. I've had alignments performed, but the problem persists. The dealer said it's within specification, and they couldn't do anything else about it. After more persistence, my service adviser came back with: The stock camber settings on BMW's are pretty aggressive, and they can't adjust the camber anymore on my car to resolve the pulling to the right issue. He said there is another BMW suspension part (control arm) they can use that will allow them to adjust the camber more, which will resolve the pull issue. The only problem is that BMW won't cover the cost to have the part replaced, which is just under $1100, and I'll have to pay for it out of pocket. I advised my adviser that was not acceptable, which prompted him to contact the service manager. The service manager said they would cover the cost of the alignment (~$185), but I would have to pay the remaining amount (~$900). After questioning the dealer further, they contacted the regional manager on my behalf. The regional manager said because the mileage on my car was so high (~40K), he would only cover the cost of the part, not labor. While I appreciate the dealer's efforts, I don't feel I should have to pay anything out of pocket to fix my car so it will drive in a straight line without pulling, especially when my car is still within manufacturer's warranty. Bottom line is that BMW now has a fix for a known issue which presents a safety hazard. BMW should fix the problem at no expense to the customer, since this has been a documented issue for several customers starting at 10 miles, after purchasing new.

The car has acceleration issues when not only adding additional speed while driving but when beginning to accelerate from a stop sign or traffic light, as well. The car hesitates when accelerating and there is often a lag in accelerating while the car is stopped or at a low speed, creating a safety concern. Not only is there a safety issue, but it is not how a $51,000 luxury sedan should drive -- it is rather rough and annoying to drive the car. The car also idles at an extremely low speed or no speed when the car is started after sitting for a longer period of time. In this case, I have to apply a decent amount of pressure on the accelerator even to back out of my garage.

Car does not respond to tip-in of accelerator from standstill. As you press harder to get intended acceleration, car lurches forward dramatically and unsafely. Vehicle is extremely difficult to drive smoothly, especially in close, stop-and-go traffic. Contacted local dealership (the BMW store in cincinnati, oh) on 9/5/11 and they are aware of the problem, but BMW is currently only providing a software patch for the 535 model. I was advised to keep driving the vehicle until BMW issues a software patch for the 528, but the dealer was not aware of any upcoming fix. I am concerned that BMW has fixed the problem for the 535, but not the 528, and that a potential fix is uncertain. This is a major driveability and safety issue.

The contact owns a 2011 BMW 528I. While stopped at a stop sign the contact depressed the accelerator, and the vehicle would not accelerate. The contact continued applying pressure to the accelerator pedal until the vehicle accelerated. The vehicle was taken to the dealer for diagnostics. The technician was unable to diagnose the failure. The vehicle had not been repaired. The approximate failure mileage was 50. Dealer rep stated that this is a known issue, but no fix has been published by BMW. Updated 09/29/2011

After purchasing a new 2011 BMW 528I (vehicle) I noticed an acceleration lag starting out from a dead stop. It has become a safety concern, especially when trying to turn onto a street from a stop sign. It crawls into the roadway when moderate pressure is applied to the gas pedal. If oncoming traffic is close this results in having to stomp on the gas pedal causing the car to jerk ahead at an unexpected rate of speed. I have had a few close calls because of this issue. Took car to dealer. They stated they reset the "learning" program that is supposed to adapt to the way one drives. This did nothing to fix the problem. After telling the dealer about this problem again, their response was that the vehicle was "operating as designed" and told me that they "all do it". since there were no trouble codes on the computer of the vehicle they said nothing is wrong with the car. This is unacceptable and I feel this will eventually result in an accident at some point when immediate and linear acceleration is needed at a critical moment.

There are 3 major issues. 1. vehicle tends to veer to the right. Feeling is quite like a vehicle that hasn't been aligned for a while. 2. the most dangerous. Upon acceleration and/or at low speed, the vehicle randomly jerks forward without any notice- making it too late for the driver to slam the brakes. If your vehicle is standing three feet behind another vehicle in stop and go traffic, you can easily crash and rear end into the car in front of you. And of course, you will be sued for not keeping your distance. This can easily cause some serious injuries. 3. vehicle wobbles as if the tires were not balanced. There are clearly unknown defects that can not be located. Took it to the local BMW dealer, they keep ascribing it to "normal" characteristics and they keep informing me that bmws are built that way, they are now sportier. However, to any new owner, it is now deadlier. The local BMW dealer also state unless they vehicle doesn't inform them about the issue they can't do anything. Its more like, until someone doesn't sue them is when they will do something about it. BMW seriously needs to look into this issue immediately before a class action lawsuit begins against them.
