| Investigations Summary: |
This investigation was opened on Sep. 10, 2002.
It was closed on Apr. 15, 2004.
Note: this investigation has resulted in
a vehicle safety recall. Ford's and Mazda's letters to NHTSA dated April 5 and April 9, 2004, state that they will recall model year 2001-03 Ford escape and Mazda tribute vehicles with the v6 engine built thru September 11, 2002. Dealers will adjust engine calibration in the programmable control module (pcm), which in its current setting, can cause the engine to shut down if the vehicle is decelerating at speeds below 40 mph. The engine shuts down due to "excessively rich air-fuel mixtures being sent to the engine. "when the engine shuts down, drivers may notice a loss of power assist for their steering and brakes. The majority of the complainants have indicated to the agency that the stall is intermittent and can happen more than once. |
