I had 2019 High Lariat 502A FX4 3.5EB Max Tow that I bought new in July of 2019. I traded it in June for a 2022 502A Powerboost FX4 Max Tow. Over the three years I had the 2019, I had the front differential replaced, the transmission main valve control body replaced twice, had the cam phaser replaced, and had the rear differential seal replaced; all under warranty. In Aug. of 2021, at around 50,000 miles the fuel mileage dropped off to 15mpg when it had previously been getting 19-20mpg. I had an extended warranty but the dealer couldn't do anything for me because it was not throwing any codes. I had a service contract with my dealer so all service was done by the dealer who sold it to me and I had their 50 point inspection, oil change and tire rotation every 5000 miles.
