Engine bulkhead covers are broken due to extreme heat. Per tsb sib-51-34-11 by BMW, this can cause corrosion inside the engine. BMW should cover this repair free of charge.

During normal operation of vehicle at 70 mph vehicle abruptly slows down below 45 mph, in the dash " engine malfunction, engine operating at reduced output. Possible to continue. Drive with caution. Have the system checked by the nearest BMW center" warning comes on the display. Unsafe to drive car on highway because at anytime car can slow down on its own.

I wish this complaint to be made public. This vehicle has had valvetronic motor components replaced three times, 5/2012, 10/2013 and 1/2015. In the first 34 months of ownership, it spent about 60+ days in service under warranty. The vehicle now has less than 29500 miles on it. I requested that BMW take this car back as an early lease return, and allow me to skip the last two months of lease payments. BMW denied my request. The most recent incident happened on 12/23/2014. While driving 65mph in the dark, pouring down rain of rush hour morning commute, the check engine light came on, and said "may be operating under reduced power." The car quickly lost power, and could only do 25 mph as I tried to safely navigate myself off of the highway as I rapidly decelerated. On the service ticket I was given at the dealership on 1/20/2015 when the repair was completed, it says: "faulty vvt motor and eccentric shaft mechanical tolerances. Followed and completed sib 12 14 10. Replaced eccentric shaft with eccentric shaft motor. Cleared faults and completed. During repair crank case vent pipe came apart due to brittle material. Also when refitting upper right micro filter/engine cowl trimming came apart due to brittle material." Unfortunately, this car is a lease, and I am concerned that BMW will sell this car to someone else. It is a safety hazard. I have refused to drive this vehicle off the dealer's lot, and have left it parked there so I may start the lease return asap. I have a moral obligation to keep others safe, and will post updated service record information to the carfax report for this VIN. BMW should be forced to answer to this problem.

After replacement of brakes on my 2012 BMW X5, upon return, I started to feel a vibration while turning in the parking lot. After two visits to the dealership, I was informed that the transfer case box (associated with the transmission) has failed. This occurs 5000miles after the warranty on the transmission and engine expire. I have done a google search on this part on X5 models, and others have reported similar experiences. This includes reports of faulty parts installed at the manufacture. BMW has agreed to cover 60% of the repair bill. This sends a red flag that perhaps the manufacture is aware of the problem and should be repairing at the problem at no cost to the client.

While driving at around 35 mph, engine started to stutter, shake violently, then completely shut off, leaving no power assist to steering or brakes. Vehicle remained dead in the middle of a heavily traveled two lane road. After attempting to restart several dozen times, vehicle finally stayed on enough to pull to side of road, then shut down again. Again after numerous attempts to restart, vehicle was able to turm the corner onto a residential street where it proceeded to shut down once again. Engine failure message appeared on vehicle information display as well as engine warning lights on dashboard. While waiting for tow truck, the vehicle sat for 15 minutes before I attempted to restart. After about a dozen attempts, vehicle restarted, but this time with no error messages or dashboard warning lights. After several additional stalls, vehicle restarted but this time with the vehicle information display indicating "engine malfunction" and additional wording stating "reduced power available" (limp home mode) and "safe to drive". based on the message and the fact the car restarted, I attempted to drive home. On the highway (long island expressway) while approaching highway speeds (45 mph) the engine again shook violently, stumbled, and shut off leaving no power steering or power brakes. Unfortunately, a tractor trailor was bearing down on my position from the rear and nearly struck my vehicle, due to the sudden power loss and catastrophic engine failure. Beyond the failure of the high pressure fuel pump (per BMW dealership), the vehicle information system is flawed as it did not remember the first catastrophic engine failure and instead reset itself. It advised although there was an engine malfunction, it was safe to drive with reduced power available. A catastrophic engine event like that should result in a warning and advisement not to drive the vehicle.

Shortly after starting the car it went into safe mode when I was on a busy road with a 55 mph speed limit which was under construction and reduced to one lane with no shoulder or place to safely pull over. Thus, I was in a dangerous situation and also obstructing traffic and putting other drivers at risk as well.

- Conroe, TX, USA

Same thing as last time. Started up the car, got it out of the driveway and the engine failed. Tried to start it again, the engine kept turning over and finally started up enough to go into the tow truck. At the BMW dealership again.

While driving at about 45 mph the engine sputtered with a message displaying "engine malfunction" and the vehicle lost power and stalled all happening within about 5 seconds. The vehicle was then towed to the BMW dealership. We were advised by their master technician that the fuel pressure rail sensor was defective and needed to be replaced (diag code: D1350_00000000_04_02 and fault 48A9 & 3F31). We asked him if this could somehow be prevented and he replied "no" and went on to say that he has never heard of this happening before. His comment was troubling to us, since we just got done driving about six hours on the freeway when this incident happened near our home. What if this happened on the freeway? I probably would not be here filing this complaint! please investigate so that this can be prevented from others experiencing this trauma.

Engine stalled. I was at a stop sign. The engine was running, when green signal came on, started to move the car, but instead of gaining speed with acceleration, the engine stalled with warning sign stating "engine malfunction, functioning with reduced power". the vehicle was not accelerating, instead was stalling and moving very slowly at less than 10 miles per hour speed and did not gain any momentum even after full throttle applied. Being a low traffic road, I was able to pull over to the right most lane; but it was a terrifying experience as the vehicle was stalling at the intersection and was moving inch by inch. I took it to the dealer, who checked everything and said everything was alright. I also questioned him, whether the event was recorded in the vehicle computer info; but he said nothing was recorded. I checked online forums and found so many people have had this problem multiple times and even after multiple services, most of the people continued to have this same problem. This is a major issue, as couple of customers have even said, their vehicles stalled on the freeway. I request your organization to look into this. Thank you.
