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.

I own a suspected Z4 with a NHTSA reported "sticky steering" issue I can tell you a little more about it. The problem has nothing to do with the boost. When the car gets hot (summer hot) the steering gets notchy in that when you put the car in a slight turn, like changing lanes or going around a slight corner, the steering literally sticks in that position causing the driver to apply opposite pressure to "break" the wheel loose from the turn followed by another stick wherever the wheel is brought back to. Problem is that it causes massive over steering issues at high speed unless you are looking for it. Extremely dangerous at highway speeds! BMW knew about it and released multiple pumas (their equivalent of a tsb) and even redesigned the suspect column, but refused to replace the older ones out of warranty. These are $3000 before labor and BMW has flat out told me that they won't cover a single dollar of it. I guess we will see NHTSA forces their hand! I am scared to death to drive the vehicle I had to jerk to out of another lane several times and you must work extremely hard to keep it straight. Please do something before someone gets hurt.
