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.

2007 engine tap on 3.3 Hyundai Sonata when starting seems Hyundai used a paper oil filter design rather than a spin off possibly engineers failed to include a oil check valve to stop the oil from draining outof the engine, engine taps for 5-10 seconds until oil gets up to motor.
