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.

problem #1

Sep 072005

(reported on)

DeVille DHS

  • 45,000 miles


Engine knocked on cold at first when new, then as time went on, all the time. Oil level was good, as was oil pressure. Dealer first told me these engines (Northstar 4.6) only knocked when cold, and quieted down when warmed up. After about 15k miles, it would knock intermittently at any time. Dealer (and you have to know a GOOD one) indicated that the repair was a replacement of all cylinders (and several other internal engine items), covered under warranty. 3 days later, and now 10k miles later, no knocks!
