Some 2010-2012 Ford Escape (and Mariner) vehicles equipped with a 2.5L engine built on or before 9-15-2011 may exhibit an intermittent no-crank, no-start conditions with no DTCs or PATS (passive anti-theft system) indicator flashing.
This may be due to improper bolt clamping of the starter motor.
1. Remove the starter motor.
2. Using a M10 x 1.5-6H tap, clean the threads of both upper and lower starter motor bolt holes in the engine block to remove any excess material. Clean the holes with shop air.
3. Reinstall the starter motor.
