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.

car shakes in between 45-60 mph

Some time in December while driving down the highway my car felt as if it was suddenly driving over mini speed bumps and continuously pulled to the right. When I let my foot off the gas the bumpy ride will cease and will clear until I put my foot back on the gas. Some days it will act up just as I explained and some days it will drive normal. Here lately it has become a daily problem. Months before this dilemma occurred I received a ball joint replacement and an alignment and everything was fine until about 3 months after. Till this very day it will suddenly start riding rough and my mechanics cannot figure it out.Until then, I guess I'm stuck driving it as is until it becomes impossible to drive and easier to diagnose.
