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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 BMW X5 Owner Comments

problem #1

Apr 222011

X5 3.0L I

  • Manual transmission
  • 98,000 miles


I just got my X5 back from BMW for maintenance on air conditioning problem. Dealer advised me that thermostat is what causing the "engine service soon" light. I drove for a week. I've asked if it's safe to drive back on that weekend and the service manager couldn't give me a definite answer. Well, I was on a bumper-to-bumper traffic for 25-30min (running 10mph) when I noticed that the temp gauge was reaching high. I immediately pulled over and shut the engine down. A minute thereafter was followed by a bang (expansion tank) burst. X5 towed to a safe place. Local mechanic removed and replaced the thermostat, expansion tank and the clutch fan. Flushed the coolant while he replaced the stuck position thermostat.
