Yes! The problem was the regulator in the alternator. The problem was intermittent so when I had the car checked they said the alternator was fine. The problem kept recurring every few weeks. Finally a new mechanic said it had to be the alternator (which I had replaced less than a year before). I had the company that supplied the alternator test it - they had it on the bench running at max output for almost 2 days before the problem showed up. Since it has been replaced about 8 months ago there has been no recurrence. Hope this helps.

60000 dollar garbage! My first ever X5, V8 still has 12000 MLS on it since purchased in 2008. Why? Because it spends more time at BMW service than I can get my hands on it!!!
Do yourself a favor and research before buying it!!!

I had the trans failsafe message appear before. Shutdown and restart cleared it. That was over a year ago. Recently it started doing it more frequently. I read a thread about the alternator/regulator causing a similar problem so I hooked up a scan guage to the OBD port that displays voltage. It read 10.9-11.4 volts while driving. That seemed low. I hooked a regular volt meter to the battery post under hood, it read 13.5 volts with engine running and 12 with engine off. That seemed right. I rechecked the guage connected to the OBD again and it now read 13.4 volts with engine running. That is a definate inconsistency which needs further investigation. Also, I've had an intermittent problem with trans initiating a shift or a disengage then re-engage( can't determine which because it doesn't complete a shift and it happens very quickly, like a hiccup). This happens around 30-40 mph when the automatic trans is in 5th gear. The last time the trans failsafe message appeared, it would not restart. It acted like a dead battery. A few minutes later it started, but the clock lost its program. The service engine light came on, but the car ran great and no more transmission hiccup. I checked code, it was P1890 trans control. I think the symtoms are related. A year ago, dealer had told me the hiccup problem was the trans valve body. They said $5500. I don't believe them. I will post results after looking into regulator and connections.

Yes - no recurrence in over a year since the alternator was changed
#55 of 61 Terrible Build Quality
Dec 27, 2010 (5:08 pm)
My '07 X5 is my 5th BMW. The other 4, including my current '02 330 CI that I also bought new, were great. This X5 drives wonderfully, but the build quality is lousy. It has 64,000 miles on it, has been maintained by the dealer to schedule, but has cost me $5,600 in "unusal" expenses over the past six months. Now the radio must be replaced ($1,600). Fuel system problems, body hardware breakdowns, windshield wiper motor issues, etc. All problems I've never before had on any car. Has anyone else experienced such concerning build quality issues?

I couldn't agree with you more. BMW used to be a quality vehicle; no more. Quality sucks!
