The egr cooler was discovered to be leaking harmful exhaust underneath the vehicle. This harmful exhaust could eventually be breathed in while the engine is running and the vehicle remains parked to run the air conditioner. Based on the mileage of my vehicle which is at 75,000 miles, the part is not covered under the emissions warranty. The odd part here is that my vehicle received a full inspection at 60,000 miles and there was no sign of any exhaust leak at this time. All that the vehicle is used for is to get groceries and bring the kids back and forth to school. Right now I am in a bad position where the cost to replace the egr cooler is nearly $2,000. If an inspection was performed just prior to 70,000 miles then this part would have been covered under the emissions warranty because I live in California.

One week ago, cooling fan made high speed noise. It kept went on and off. One week later, "engine hot" sign turned on while I'm driving on highway. I turned off the engine and turned on 20 minutes later. After I turned on, engine oil level shows up empty, 0. we changed engine oil when 45,000 miles and current is 50,000 miles.

Vehicle mileage 56,341mi. Vehicle engine would crank but not start after coming out of business while running errands. Dash warning message "engine malfunction" was present. Codes read via generic obd2 device were P10E4, P10F5, P10E5, B2aaa. These codes are related to the valvetronic system in the engine. Checked related fuses and no problem. Had to get vehicle towed to dealer. Dealer diagnosed that the valvetronic system error. Vehicle was first reprogrammed and issue remained. Valvetronic system was replaced due to dtcs that led them to believe eccentric shaft was stuck. Talking with the technician the eccentric shaft was not stuck and he assumed the actuator\ motor had failed. Per BMW instructions the entire system was replaced though. Technician stated that he has done many replacements of valvetronic systems and the parts were already in stock which raised a flag to me. The engine was reassembled and the engine would still not start. There were faults left in the engine control unit. Apparently the engine control unit was damaged by actuator\ motor that was drawing high current.(confirmed by BMW service engineer) engine control unit was replaced and reprogrammed and engine is now reported to be in operational condition. BMW and dealer has discounted the service and provided a loaner vehicle but based on information from the technician this entire repair could possibly be a recallable item as it can leave the end user stranded and with a healthy repair bill with a vehicle that is not too far out of warranty. Repair bill has been uploaded.

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.

X5 6-cyl

  • 55,000 miles
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.

problem #5

Aug 022014

X5 6-cyl

  • 6,600 miles
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.

X5 6-cyl

  • 56,000 miles
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.

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.
