I would start with the basic preventative maintenance items like you said. 
cap, rotor, plugs, plug wires, and fuel filter. 
For the engine temp, make sure the impeller is good. Also, clean the screen on the oil cooler heat exchanger. What was the temperature displayed on the screen? 
 

If the impeller was used for 30 hours and then sat in the garage for 2 years, you may want to remove the cover and inspect for broken / missing vanes.

Considering mouthguard. Efoil accident three days ago. Broke my mandible.

Two days ago had complication from injury and surgery. All airways became blocked. Without swift medical attention while recovering in the hospital, I was at great risk of death.

Researching the idea of a watersports mouth guard and plan on using one. Already use a helmet and life vest (not an impact vest).

Please feel free to post this.

A bit of an update. We headed to the lake last night - same one I had the high temps driving to last time. 
 

Not much wind but air temps were about 10* warmer (low 90*s). Towed the boat with my Grand Cherokee L. It did much better than I anticipated. Road manners weren’t any different than the Ex. I never saw about 187* transmission temp. I was actually impressed with that. 
 

Got a call from the dealer the Ex is at this am. They are working super fast, just buttoning everything up now. 
 

Replaced the cam phasers (said they were shot). I’m amazed the last dealer saw/heard no problems with them. 
 

New timing chains installed as well. New valve covers and water pump. New transmission and new transmission cooler. New front diff. 
 

Around $20k worth of work a month away from end of warranty. 
 

I am super impressed with the new tech and dealership. Disappointed in the last dealership and surprised ford would put out a product like this. 

This post is why I choose to drive 3 1/2 hrs for a Malibu dealer. Even when we have a dealer within 15 minutes of where we boat 98% of the time. 
 

Perfect pass website; manuals, videos, troubleshooting info all available on their site.
