Transfer case actuators plastic gear(s) might be worn out due to bad quality of the material used. On some of the BMW X5 models there was a problem with the differentials and a recall was issued to fix those. But some how some cars with particular VINs went missing in that. Codes thrown by my system are : 005219, 005F3A, 006EC4 Code 005F3A signifies that the Transfer case actuator is not engaging properly. This problem put me at risk when taking a U-turn as the gears did not engage properly and my car did not accelerate on time. The on coming traffic came very close and I somehow avoided a T-bone Collison. My cars dashboard produces warning signs occasionally when the actuator does not engage. This is a big problem as the 4x4 system stops working and puts the car in RWD mode. In winters this could be dangerous to people driving as it happens without the driver's attention. I have attached reports from NHTSA for the same issue on other BMW models where a recall was issued. I request NHTSA to issue a recall on 2011 BMW X5 xdrive 35i as the same issue persists.

Driving the X5 on dash display appeared the warning for parking brakes malfunction. 9the vehicle was in motion on city street). From that time the parking brake is not working anymore, the dash message stays on and I have the error on display. This is a manufacturing problem for the electric parking brakes, many people experienced the same problem. This is safety problem for nor=T be able to safe park/stop the car on sloped roads/parkings.

2011 BMW X5 35I xdrive - my drive shaft broke (violent banging noise from the front of the car) while I was going 65 miles per hour on the freeway causing me to swerve to the left lane back over to the right lane. Super lucky that I barely missed hitting the cars next to me! I had hardly any control of the vehicle and the engine was still running while I coasted over to the side of the road / ditch. I lost almost 7 quarts of oil on the side of the road. My engine has a hole in it from the drive shaft. I did not receive a recall notice in the mail. The manufacture will be replacing my engine and some hoses that were destroyed. The dealer said this wasn't a recall, just an extended warranty since we have approx. 70,000 miles on the car. The dealer gave us a loaner car to use until our car is repaired. My concern is that owners should be notified immediately! had I known, I would of had my car inspected... now I'm out $325 dollars for towing expenses, a car that might not ever be quite the same, live 1hr 20 minutes from the dealer, and the memory of the dramatic event.

While driving my engine suddenly shut off along with power steering and power brakes. It started again and I took it to a BMW dealer that said I needed a $325 software update. I asked if that meant my engine would shut off while driving should by software ever go out of date. They said yes, it happens but not on all software updates. They also said software update come out about every 3 to 4 months meaning my engine could be shut off again at any time. I felt I had no choice but to pay the money so my car would run again. I am concerned now about driving at any higher rate of speed considering I could lose my steering and brakes anytime someone decides I need to update software that I was never informed was out of date.
