Looking at a 2012 - any advice?

Recommended Posts

2012 is a good year. There may be a few software updates that you'll have to check with Ford with the VIN to see if they were done. If they haven't been, they should be done. With hot summer temperatures there's a little mpg hit. Park in the shade with moonroof and windows cracked. The AC is strong but power hungry. 40-50 mph is an optimum speed. Max EV speed is 47 so you should avoid that speed as it sometimes shifts back and forth to EV too much.

Some years of the 2010-12s had 30% sold to government or fleets. I don't think it really matters, in fact fleet maintained cars may get better maintenance and there's not really much you can do to hurt those cars except brake harder which just means some brake pad wear. They only need oil and filter and cabin air filter changes and tire maintenance. There's very little maintenance required to 100K miles. After that, spark plugs, coolants and that's about it. No alternators, automatic transmissions, timing belts. They have some expensive parts like the DC to DC converter, the HV electric AC compressor, and the brake simulator. These haven't been failing much so far. The hybrid components have been very reliable.

When driving at ~30 mph with car warmed, it will go about 1/2 mile on the ICE, then 1/2 mile in EV and repeat that cycle. There are many reasons why the 2010-12 ICE will run:

1) Evaporative emissions check on starting for about 1/2- 1 minute after selecting D or R.

2) Catalytic converter warmup for about a mile of driving above 12 mph. Thermometer on temp gauge turns green.

3) Significant power demand- acceleration, climbing a hill

4) Speed above 45 mph

5) HVB SOC low

6) Very high or low outside temperatures ( to provide system cooling/heating)

7) ICE not warm enough to provide cabin heating.

8) HVB re-conditioning event

 

A re-conditioning event causes the ICE to run until the HVB is at ~100% SOC. EV is disabled except for R when the re-conditioning will be cancelled. Re-conditioning balances the 204 cell voltages and chemistry. My 2010 does it about once a year. After one event, I was able to drive 4 miles at 40 mph from the 100% SOC. 1/2 mile is normal from the usual 50% SOC that the system averages.

 

Did you have the drivers seat all the way down and back? It is an easy car to get in and out of.

 

There are 4 dash display modes. The most information is provided in "Empower" which has a function that displays the limit of available EV power compared to the present demand.
