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.

2006 Ford Ranger Owner Comments

problem #6

Fuel inertial cut-off switch activates randomly, usually once or twice a year. Result is sudden unexpected loss of engine power. Can happen while driving in town or on the freeway. Does not matter if the vehicle is moving fast or slow. The device can be reset by pushing a button but the device is not accessible from the drivers side while driving. Dangerous as the loss of power is total, immediate, and without warning. The is currently no recall for this item but I see from your website and other websites that this problem has happened to other people.

Rough idle noticed while stopped at an intersection. Catastrophic misfire upon acceleration through an intersection. Truck was only able to "limp" 5 or less miles per hour. Check engine light had been turning off and on however diagnostics showed misfire for unknown reasons. Spark plugs and wires had been replaced twice within a year as well. Defected head manufactured by Ford.

2006 Ford Ranger. Consumer writes in regards to vehicle defective cylinder heads. The consumer stated according to Ford technical service bulletin 05-26-3 the engines were built at the factory with defective heads. If the check engine light illuminated, the heads needed to be replaced, as it was explained to him by a mechanic at a Ford dealership. The consumer stated it appeared to be defective materials in the heads, which required the heads to be removed and scrapped, along with the head gaskets. The heads appeared to be made of soft iron, where the base metal was perhaps not heat treated. The estimates for the repair of the engine, were between $3,000-$6,000 depending on what was needed to fix the problem.

The contact owns a 2006 Ford Ranger. The contact stated that while driving 45 mph the engine misfired, causing the vehicle to rough idle and stall. The contact took the vehicle to a local mechanic for diagnostic testing. The test results concluded that the vehicle needed a tune-up. The tune-up was performed however, the failure was not corrected. The contact took the vehicle back to the local mechanic where a second diagnostic was performed, concluding that the vehicle was in need of a tune-up. The vehicle was not further serviced. The failure mileage was 160,000.
