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.

Engine knocks when first starting unless it warms up for a couple minutes. Goes away quickly when driving. No oil loss; no power loss; just embarrassing. Dealer commented common with older GMC trucks and was nothing to worry about. Asked if I used their oil filter. Anyone else hear or have this problem.

Thanks,
