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.

During a cold, driving rain storm, with driver & 1 passenger, started to drive. (very 1st drive in this car with cold weather) what a surprise: Windshield immediately fogged up. Turned on defogger, windshield then fogged up 100% as well as all other windows - as visibility disappeared, I stopped the car & opened the windows with the blower on. No heat could be used. This process was repeated over the next 1 to 1-1/2 hours in order to continue driving. Issue was reported to BMW many times over. I had to learn that despite cold ambient temperatures w-w/O rain, snow, etc. - the A/C must be turned on in order to not fog the windows. BMW: There's nothing to fix, that's the way it is. The ambient air is directed through a portion of the engine compartment, this heats up the air. BMW stated that I may void the warranty if I modify the system to correct this problem. This has continued to occur. On a drive on ca's coast highway, with temps in the low 50's - one must still run the A/C & no heat. BMW asked: What do you have against running the A/C all the time? in addition to impaired visibility - this results in constant, very low mpg with the A/C always on. When BMW provided mpg's to fed. Agencies, I believe that BMW's A/C's were not on & these cars demand premium fuel. I spoke with a nationally known, respected tester/advisers of many vehicles - it was confirmed to me that the mpg tests are conducted without the A/C's being turned on.
