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.

My vehicle will not start followed by a 10 minute lockout period. This happens every few days. Once the vehicle sits for 10 minuted it will start. This happens regardless of wether conditions, will persist intermittently anytime of day; does not have anything to due with key fob or how I enter the vehicle.
