I have a 2006 Ford Escape Hybrid with about 150,000 miles.
It sometimes is lacking normal power - slow to start but fine once to full speed. When it is lacking power I notice that the gas engine is not shutting off when stopped at traffic signal like it normally does with charged batteries. It will be like this or a few days and then suddenly has its normal power and shuts of at traffic signals again.
Seems to be some failure of communication in the hybrid controls with system not telling the electric motor to do its thing. Any guidance out there as to where I should start looking for fix of this intermittent problem?
