Two problems related to engine exhaust system have been reported for the 2012 BMW X5. The most recently reported issues are listed below.
Scr catalytic converter failure and nox sensor failure in diesel exhaust system on a 54,1xx mile vehicle -- much too early for these systems to fail . The system alerted me of a "exhaust fluid incorrect" cel with a 200 mil count down timer. This count down time renders the vehicle immobile if you do not bring it into the BMW dealer within this mileage. This count down timer could have left me literally stranded in the middle of no where if I were to take this vehicle on any road trip or extended travel. I believe it is absolutely criminal that BMW can disable your vehicle on an emission related issue potentially leaving you stranded. Yes, I would have (and have) brought the vehicle in for repair -- immobilizing the vehicle is absolutely ridiculous and should not be allowed and is very unsafe and could have caused me and my family harm. I have a 2 year old and a 3 month old that could have been left stranded. I'm afraid to drive this vehicle with my family now.
