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.

The cooling system and defrost shut down after driving for a while. Turns out the clutch went bad on the compressor. After researching further online, there are many complaints about this failure. Unfortunately, this is a very expensive repair that I cannot afford.

S40 5-cyl

  • 78,000 miles
I own a '07 Volvo S40 with 78,000 miles. It began making a loud whistling noise coming from the oil dipstick. After researching online I found that it was a known problem by Volvo and the defective part is covered under an extended warranty, however this defective part causes excessive damage to the engine that is not covered by Volvo. It is now up to the consumer to pay for the engine damage or it will cause the timing belt to snap and the engine to explode. An unsuspecting consumer can be fatally injured by this problem and something must be done about it!
