I have a 2012 MKZ Hybrid, and starting about 4 or 5 months ago, my MPG started to decrease dramatically. I bought the car 4 years ago, and I've been consistently getting over 33 MPG, it's now down to 26 MPG. The HBV is fully charged, but the electric drive is rarely engaged anymore. As soon as I turn the car on, the engine starts. The car is in great shape, and I don't want to get rid of it. Has anyone experienced this? Has any heard about Lincoln building a time limit on their HVBs? I saw a posting on the Ford Fusion Hybrid forum that indicates that the Hybrid EV drive is limited to 8/9/10 years based on expected HVB lifespan. Has anyone tried the procedure discussed in this post on the Ford Fusion Hybrid forum?
