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.

Recently started hearing a 'humming' noise from engine. The best way to describe the sound is when you hear an off road vehicle driving on a regular road... you know that hummmmm the tires make... that is the noise we are hearing from the engine compartment after 30mph, no sound at idling, no sound under 30. It is def. not the tires making this sound as when you roll the windows down you are not hearing the sound coming from the tires. Plan on taking to shop this week but was searching the net to see if anyone else had this complaint.
