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.

Just had the radiator replaced twice in past 3 months. Now the engine knocks in the morning for a couple minutes. Took it to repair shop and they want to charge $3500. to repair or $5000 to replace the engine. Let's see, we've owned the truck since new in 2004, and have had the the dash torn apart a couple times because of all the electrical problems (ie, airbags (light still on), air conditioning (twice), passenger window electrical replaced twice, driver seat electricals replaced once, the shocks) and this is just what I remember. I'm confident the list continues once I pull out all the repair bills. My husband loves this truck, but I don't think it's worth keeping. grrrr!!! Took six years to finally pay it off and we are still paying for it!

This knock is annoying. I know it's a huge problem and it seems everyone that has this engine has it. They need to do something.
