I, too, am at 60,000+ on my 2017, and wondering if things have gotten any better BEFORE I call my local dealer service dept.  These dealer visits are always anxiety-ridden enough as it is, I do not need to also worry now whether or not they know EXACTLY what they're doing.  That is the ONLY reason I would avail a dealer service center in the first place - out of concern (fear) that my regular automotive-service shop (which is one for the absolute best I've ever had) might take a "first time" swing at my Hybrid, and unintentionally screw something up.    Much appreciation in advance for anyone who might have advice or suggestions..   Thx....

I've never heard of a "lifetime" engine air filter before .. apart from the ones K&N makes that are "washable" .. the internal combustion engine in the C-MAX is not "magic"  ..  I remember the dealer shop guy look at me strangely when I questioned him replacing it at 60,000 miles but I think he made the right call.

Heh heh,  yeah good idea to do stretching exercises before doing that one.  😀

Cmax air filters are tedious.  My engine air filter didn't look too different to the 'mouse nest' one above.  I was tempted to 'let it go' for another year, but decided to change it; I similarly sucked up some monster cotton/felt/debris.  Not concerning since the filter caught it, but that was unexpected.  For my cabin air filter, I threw the retaining screw away since the plastic cover snaps into place although the cabin air filter requires some gymnastics.     Greg

Thanks cr08.  I'm trying to update the turn signal light bulbs with LED bulbs.  Some advertise that they come "with Build-in Load Resistor CANBUS Error Free" --Would these eliminate the hyper-flashing?

It's built into the BCM and is not replaceable.

Where is the location of the turn signal/flasher relay in a 2013-16 C-max energi?

He probably knows what a pain it is to change this filter and got advised from the techs to send customers away by telling them "lifetime"😁 I changed mine a few times already and it gets faster once you know how to.

Not sure about a dealer installed. And I think most have taken the '2014-2017/18' years on the original bulletin as a hard limit on which ones they'll upgrade even though personally I think it wasn't intended to be interpreted that way and just what they covered under the free labor provisions.   But I have a 2013 SEL and DIY'd it and it's been running perfectly aside from Ford dropping all the useful features which isn't specific to the '13s and affects everyone.

I tried wading through the 14-17 4g topic. Just wondering if anyone had a dealer upgrade their 13 energi to 4g?
