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.

It did not start in hot weather. Coolant leak. It must be fixed otherwise the engine will be gone. I have a warranty for a year or 20k.

Venture LT 3.2L V6

  • Automatic transmission
  • 68,000 miles

This has happened twice now. The great redesigned gaskets lasted 50K miles only !!

Have to dump the vehicle which is a shame because otherwise it has been very good.

But now the front wheel bearings are bad, another common problem with these Ventures.

Read about Dex-cool coolant.

Do not buy.

Venture LS 3.4L

  • Automatic transmission
  • 92,000 miles

My Venture heats up when idling or not moving. The problem is the &$*# Dex-cool Coolant!!!! That is the cause of all of the gasket failures, etc. When the engine gets hot (from motoring), the Dex-cool actually erodes away at the gaskets inside the engine. If we would have all known about this when we first bought our Ventures, we would have all left the car dealer's lot, gone straight to a place and had a "flush and fill" done to removed all the Dex-cool coolant and replace it with a universal coolant. Then we wouldn't have these gasket issues!!!! I am SO MAD!!!
