Hi all!
Long time reader, first time poster. I have a 2023 XLT hybrid thats been great for the last few years. 35000 miles so far.
But recently on a road trip I had an issue with the EV battery where a circuit was stuck closed and required the high voltage junction box to be replaced. I was in Canada and the Ford dealership up there was able to do the fix. Drove home (about 600 miles) with no issues.
Two weeks later, and my mpg has absolutely tanked. I usually get about 41-43 mpg per tank, and now I’m down to 29. The problem seems to be when the gas engine comes on. Looking at the instantaneous mpg, it still displays “electric” when driving in the city or coasting on the highway. But when the gas engine kicks in, the mpg drops to 7-10 when city driving, which is well below the 17+ it used to be.
My suspicion is that the electric motor isn’t contributing as much when the hybrid engine comes on, but that’s little more than a guess. No warning lights are on, so I don’t think it’s anything dire, just not running optimally.
Wanted to ask if anyone else has had a similar problem and what the eventual fix was? Planning on taking it to a dealership soon, but have no idea what I’d ask them to check.
