I started my car to drive to an appointment and noticed that the car was jerking/bucking as I pulled out of my driveway onto the main road. I was unable to accelerate appropriately for oncoming traffic behind me because the car was jerking violently and it was a bit scary since this had not happened before. This continued for several days, primarily when I would attempt to drive the car in the morning. On one occasion the drive train malfunction light illuminated as I was making my way to an appointment at the Veterans Administration and I had to gingerly turn the car around and head back home. Someone could have ran into me because the car didn't have much power. What followed next was the inability to get my car to move when it was placed in reverse. I took the car to the dealership and was told that the car's transmission needs to be replaced ($11,000) because the car is trying to drive in reverse and first gear at the same time. What?!! In over 20 years of servicing BMW's, they have never seen a situation like this. I don't believe I should bear the cost for this when I bought a pretty expensive car in good faith, which has only 80,000 miles.

This vehicle when being used has excessive consumption of oil and oil leaks. This problem cause the engine, engine turbos, valve stems and seals and oil pan seals to go bad prior to normal vehicle engine/part life. There is currently a settled class action lawsuit that replaces the engine at a percentage based on miles on car at time of bad engine test. But I believe this is also a possible safety issue and should be treat more like a recall not a suit. You can view more information regarding this suit at https://bangclasssettlement.com

The driver door does not shut intermittently the door release, door unlock/lock, door handle does not release the state. The car won't move because the door is not locked, it can take upwards of a few hours of tinkling to get this going again. The dealer has diligently changed so many parts and its not that they are not trying to remedy the situation. Is anyone else experiencing this out there. My 4 yr warranty will end in June and I am vvery concerned how I am going to resolve this issue.

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.
