Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2012 BMW X5 Owner Comments

The fuel pump suddenly failed while driving on the highway at 75 mph (legal speed limit) with no warning and caused a stall condition. I noticed they (BMW) have a new recall for up to the 2011 model year but they need to include the 2012 as well.

We used out 2012 BMW X5 diesel for a round trip of mn to fl. October of 2015. We had the vehicle serviced prior to departure and asked if there was anything we needed to be aware of for the long trip. Upon return trip back to mn we were alerted by the system monitor that the diesel exhaust fluid (def) was low. We were 5 hours into our 18 hour trip from fl to mn. It was Saturday after 1:00 pm and we stopped to add def to the system. The fill port on the X5 would only accept 4 oz of def with repeated attempts to fill the reservoir. We used the internet to search the problem and found that with out the BMW container of def the reservoir would not accept enough def to fill the system. We also discovered that there are two reservoirs. The BMW manual did not state that the BMW bottle was needed nor that there are two reservoirs. We could not purchase the BMW bottle as no BMW dealerships were open, nor would they be the next day. The BMW system also stated that the engine would shut down after the 200 mile limit was reached. We had to stay overnight in our current location and then drive 12 hours the next day, Sunday, with out shutting the engine off as if we did the BMW override would shut the engine down and we verified that fact on the web. We made it home and as soon as we shut the engine down it was disabled. We purchased the BMW def bottle and filled they reservoirs. The system did not rest and the vehicle had to be towed to the dealer. It took them 3 days to reset the system and then discover the O2 sensors were now not functioning and needed to be replaced, due to the def issue. Cost of the O2 sensor replacement is $2000. The system will leave you stranded.BMW's owner manual is incorrect and no one will tell you that you need the BMW engineered def bottle to refill they system. We contacted BMW North America without any results.

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.

I tried to start up the car, it started, I drove a few feet, and then failed. I received a warning message saying that the engine malfunctioned. I was in the middle of the parking lot so I managed to get it to start again, it barely moved, and then failed again. One more time I was able to start it and get it into a parking space. I tried to start it up multiple times again but nothing happened. I called BMW to have it towed.

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.
