Thanks. I guess next time it happens, I'll pull out my code reader while the warnings are active and see what I can come up with. A bit frustrating because the problem clears itself after driving a little ways down the road.

Automate, That matches my understanding of freeze frame as well: condition of sensors and other data at the time the DTC or some other interesting event happened. This is exactly what I'm asking about. On my 2010 Toyota Tacoma for example, the onboard ABS computer saves freeze frame data when the ABS activates, in addition to when a DTC is set, for example. I guess would need to purchase the factory service manual to see if the Fusion has anything like this capability available.

Could someone who knows more technical details tell me whether the onboard computers in the Fusion have the ability to save and store (ie, snapshot) intermittent failures like this? There's no DTC being stored, but I know other vehicles can save data about failures beyond simple DTC codes. I'm wondering if the Ford service department response "sorry, no codes, can't help you" is legit. Thanks

Not really curvy. There's two 90 degree corners in the entire length. Appreciate the suggestion, thanks for responding.

Hi all. Looking for some collective wisdom here to help solve an annoying intermittent issue with my 2013 FFH. I searched and found a couple similar looking problems, but not exactly what I have going on. My house sits at the end of a 1000 ft. gravel driveway, all downhill, and approximately 12% slope. Every couple of days, the car will display the "Hill Start Assist not available" and "Service AdvanceTrac" messages on the instrument cluster. The two little yellow car "skid" icons also light up solid, stability control lamp (means: malfunction, according to manual) and stability control off. No adverse effects or driveability is noted. Less than 1/4 mile down the road, the lights just go out by themselves while driving the car and everything is normal again after that. There is no correlation to temperature, wet vs. dry day, or anything else that I can think of. I put it in Engineering Test Mode and no DTCs come up. Dealer supposedly scanned for codes but couldn't find anything wrong? This is super frustrating since it's highly intermittent. Anyone seen something similar and have any resolution? Thanks
