I’ve got a 2024 Maverick Hybrid XLT that’s part of a fleet, and I’m having trouble getting decent cabin heat during the winter. Fuel efficiency isn’t an issue, so I’m looking for ways to maximize heat output. Here’s what I’ve tried so far:
Setting the climate control to max defrost before leaving the vehicle for long periods.
Remote starting the truck and extending the runtime.
Using sport mode while driving to keep the engine running.
Leaving the truck running between service calls.
Keeping the heat on max and adjusting fan settings manually.
Despite all this, the cabin only gets warm, not hot, unless I’m on the highway. For comparison, I came from a 2023 Transit AWD EcoBoost that would have roasted me out after 1.5 hours of running max heat. Why is the Maverick Hybrid’s heating so underwhelming?
I’m wondering if there are any ForScan settings to help—like running the strip heaters more often, increasing idle speeds, or forcing the engine to stay on during remote start.

Turning on defrost automatically runs the A/C. Is there a reason you want to run the compressor constantly? Also, have you set the heat to max?
Most vehicles don’t run the A/C compressor when it’s really cold outside.

I use max defrost to force the engine to stay on and turn off the A/C option when I can. The A/C seems to be fully electric, though, probably powered by the high-voltage battery.

You can’t fully disable A/C in defrost mode—it’ll still cycle. Defrost also doesn’t allow recirculated air, so you’re always pulling in cold outside air. Try switching to recirculate mode with air directed at the feet and forward vents instead. Also, the owner’s manual recommends using auto mode and letting the system manage itself.
@Keegan
Problem is, if I pick recirc, the ICE doesn’t stay on long enough to generate heat. Is there a way in ForScan to adjust idle speed or prevent the hybrid system from taking over during high heat demands? With anything other than max defrost, the engine just doesn’t run long enough to generate decent heat.
I’ve got a 2022 Lariat Hybrid, and I’ve never had heating issues. Remote start for 5 minutes, and it’s toasty. Heated seats and the wheel make a big difference, though. Might be worth getting it checked out.
Sounds like you’re not in auto mode. Auto engages electric heat and manages the airflow better. Defrost mode is constantly pulling in cold outside air, which doesn’t help. Try setting it to auto with recirculate on and let the system handle things.
Hybrids do run cooler below freeway speeds—it’s just how they’re designed. Heated seats and steering wheels (luxury package) are a must for cold climates. If you don’t have those, aftermarket heated seats could be an option.
@Zeke
I’m more concerned with keeping the windshield and windows clear than my own comfort. But heated seats and steering wheels would definitely be nice for future vehicles.
I drive a Lariat Tremor (AWD EcoBoost) and have zero issues with heat. It warms up fast and stays warm. Same with the two XLs in our fleet—both AWD EcoBoosts. They’re also way more fuel-efficient than our old V6 F150s and Transits.

So the takeaway seems to be: stick to vehicles with conventional engines. Thanks for the feedback!
Well, hybrids are much more efficient because they generate less waste heat. If your company allows it, using the block heater might help with quicker warm-ups. Otherwise, you could look into an auxiliary heater like a Propex.
The Atkinson cycle engine in hybrids is highly efficient, so it generates less heat. Try using tow mode instead of sport mode—it keeps the engine running longer. Also, if you need the engine on, pressing the gas pedal in park should start it up. About the 3x fuel consumption comment, were you referring to leaving the engine on all day?
I’ve got an XLT hybrid, and I never notice heating issues because the seat warmers work so well. Maybe try cranking everything up to get the engine to run more.
You don’t need to leave sport mode on. Just press the auto start/stop button (the one with the circular arrow and an ‘A’ in the middle) to keep the engine running. Sport mode is fun, but it’s not necessary for heat.
