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.

thunking noise coming from the passenger-side rear end. going down the road at any speed and turning corners makes it louder. all brakes have been replaced new rotors to the back front are about a year old. calipers are about a year old but were replaced three times because they kept seizing. struts are about a year old but have been replaced three times in the last 2 years. everything seems fine looks fine but is not. this is by far the worst car i have ever had. just to give you an idea i bought it used in 2000. by 2001 i needed a moter, went with no warning, have replaced struts in the back three times front struts upper and lower mounts last year, lower ball joints three times, tie rods three times, all in a year, transmision last may, all but one o2 sensor, ignition control sensor coolant sensor other sensors i can't remember what they were called ive had so much done any suggestions?
