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.

Okay well I got a mechanic to check my car, there is no fuel leaks or whatsoever, we did find an oxygen sensor malfunction( bank 1) I did fix it and bought a new one but the problem is still reoccurring. The computer to check my car only detected that as a problem, now it shows nothing going wrong and my car takes 46 L per 100km and it's starting to cost me alot. It takes a way larger amount of gas when it's really cold outside. Anyhow it is literally not bearable it cost me 250$ of gas this week and i didn't move alot.
