Hello All,
I have a 2023 Maverick Tremor I purchased new in May. I've been very happy with the truck thus far and have a little over 11K on it. However, when the weather turned cold this past week, I got a check engine light and notification that the engine took too long to warm to operating temperature. It was about the mid 30s at the time, so nothing extreme in my opinion. I thought it must have been a fluke and reset the light. It came on again the next day in almost the exact same place on my drive to work. I'm waiting for an appointment for the dealer to take a look, but I've also found at least two others who have posted about this issue on mavericks, and several on other forums for other Fords with Ecoboost engines. In each case that I've found online, no one has stated a solution was found for the issue.
A few things I've noticed since the light came on: my gas mileage has gone from 24 MPG average to 23 MPG average in only a weeks time (obviously running less efficiently due to operating temp); the engine temp bars fluctuate between 2 and 4 bars, in some instances, less than a minute depending on driving conditions. If I"m pulling a hill it will spike to 4 and on the decent go back to two. Although I dont like getting less MPGs, that is less my concern. I've never driven a car that fluctuated in engine temp that dramatically. I have had vehicles in the past with defective thermostats either stuck wide open or failing to close all the way cause similar issues. However, one individual dealing with this issue on his maverick reported that the dealer changed the thermostat and it did not correct this issue. This leads me to believe something else is going on here.
Has anyone driving an ecoboost experienced this? If so, what were the solutions you were offered/worked to actually fix the problem? Its really bothering me that a new truck is having an issue like this. I've always driven beaters and this was supposed to be my "dont need to worry about it" vehicle to get me to and from work everyday for a few years. This is also my first Ford (always driven Toyotas), so I am also having some regret in changing my normal position that Toyotas are king of reliability. If anyone has any input they can share about this issue, I would appreciate it.
