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.

First occurrence about 87000 miles was traveling on freeway when car stalled. Started it back up and check engine light came on. Took vehicle to dealer and they installed new spark plug and wires. Stalled again at about 89000 miles and was told to bring back when check engine light came back on. Check engine light came on again and took vehicle in on Saturday but store was remodeling and couldn't get me in. Took car in for 90000 mile service and check engine light was on. Was told that spark plugs were installed. I informed them I had spark plugs and wires installed the last service and that this stalling of my vehicle is dangerous. Was told that after the spark plugs were installed it cleared the check engine light and that I would have to bring the car in again when the check engine light was on. Dealership has been of no help with this issue. Looked online for people with similar problems and it points to recall #08V033000.

The contact owns a 2004 Volvo S40. The contact stated the brake warning light would illuminate while driving at any speed, causing the vehicle to shut down. The vehicle was taken to the dealer three times for the failure and the dealer reprogrammed the computer software each time. On a separate occasion, the failure recurred and the vehicle was towed to the dealer. The dealer advised the computer module would need to be replaced. The manufacturer advised an inspector would assess the failure further. The contact was awaiting results. The failure mileage was 36,000 and the current mileage was 40,000.
