no start 
2007 BMW X5 SUV 4.8i 4dr SUV AWD (4.8L 8cyl 6A)
No start
 Great riding car.  Great design.  Terrible starting problems.  Have had 4 random no start situation.  Two in garage, but two out on roads where tow truck was needed.  Car has been in shop 8 days with this problem and have not been able to find problem to date.  Scary, as you don't know when it will not start.  Am getting rid of car now and will buy a Lexus for dependability.  I have been a BMW owner for last 20 years.  They have over the teched the car.  Was told it has over 50 computers in it.  Problem is, how many work properly.  Do not buy.
