“Oil separator problem with 2006 Bmw X5, caused engine to shut down in the middle of the highway. I'm told that this is a problem when driving in cold weather and there is nothing I can do to fix it. $1500 repair and still no assurance it won't happen again.”

NHTSA complaint #10384723, filed 2011-02, 73,000 miles

“Approximately 1 month after having our Bmw serviced for an oil change at our local dealer, the check engine oil level light illuminated. We immediately called the dealer, and upon them looking at it, it was determined that the crankcase vent valve (oil separator), needs to be replaced, at a cost of $1,300. We have been having this light come on numerous times over the past couple of years, and always call the dealer when it does. Every time we call, they either tell me to top the oil off myself, or we bring it to the dealer for them to top off. …”
