Really BAD issue with remote start Fordpass... Hybrid Maverick

[Ohlawddd]

XL Model here with bunch of upgrades.

So this was the first morning I got to test out the remote start with FordPass.(I did try it once before when setting up Fordpass) I have owned the truck since the 23rd of DEC, so.. 5 days, no issues. About 300 miles on it.

I got up to get ready for work, hit the remote start on the Ford Pass, it said the vehicle was started, and I went about getting ready, letting dog out, bathroom etc.

Well all that done I went to go out and head to work, and first thing I noticed was the truck was making a god awful noise like it was constantly starting and stopping every second. And then this smell hit me...

It was an incredibly intense fuel smell. Almost like rotten eggs. Unburnt fuel maybe? It actually made me almost physically ill.

Well I had to get to work, so I got in the truck rolled down the windows, and put the key in an shut the truck OFF. Then I turned it on, it said ready to drive, and I drove to work. No issues, no weird noises, no more weird smell. It was a cold drive to work for sure, but had to air out the original smell.

I mean I actually still feel a bit ill from it.

I guess Im going to test it out tonight after work and just keep an eye on it and watch it remote start. I dont believe in "flukes" when it comes to car reliability, so I still will talk to the dealer.

For context I did technically test the remote start via fordpass when we initially set up Fordpass at the dealer, so THAT time, it appeared to work fine.
It was particularly cold this morning, maybe 40 degrees F.

I have been experiencing a weird odor as well, Anytime I remote start and its 20 degrees or below. The interior smells like burnt soft pretzels. I doesn't make me feel ill but its definitely unpleasant. I know what the catalytic egg smell smells like but this is nothing close. Also the engine is revving from what I would assume idle to 2k RPMS. Which would make sense i guess to help warm it up but that's when the smell usually occurs (hybrid)

"burnt soft pretzels" isn't that an oxymoron?

The debate about whether or not there is an additional electric heating element in the Maverick has gone round and round, but the post below is intriguing. Could the smell be the element operating for the first time?

https://www.mavericktruckclub.com/forum/threads/hybrid-heater-performance.6932/post-165839

From section 412-03, "Supplementary Climate Control", of the 2022 Maverick service manual:

"Electric Booster Heater Operation

The electric booster heater ensures that the passenger compartment can be quickly warmed up when ambient temperatures are low. It is a heater element made up of ceramic resistors that is mounted in the climate control housing. It directly heats the airflow into the passenger compartment rapidly in the case of low ambient temperatures.

The current is switched via three electric booster heater relays located in the BJB/ BCMC. The HVAC module sends a request message over the MS-CAN network to the GWM. The BCMC receives a network message over the HS-CAN1 requesting to apply power and ground to energize the relays. The electric booster heater is supplied voltage from the relays and has a dedicated ground circuit.

The HVAC control module energizes the electric booster heater relays when the operating parameters have been met. The electric booster heater relays are activated or deactivated individually or together by the HVAC control module as needed.

Electric booster heater operating parameters:

-Engine is running
-HVAC controls have been switched to the highest temperature setting
-Engine coolant temperature is below approximately 75°C (167°F)
-Ambient air temperature is below approximately 12°C (53.6°F)
-Sufficient generator capacity is available

The electric booster heater is deactivated when an engine coolant temperature of approximately 85°C (185°F) or an ambient air temperature of approximately 15°C (59°F) is exceeded.

Component Description

The electric booster heater, also known as the PTC heater, is made up of three separate ceramic resistor elements."

Wait is the service manual publicly available? Where can I get it?

haha in a parallel universe that is the smell I'm getting

No, but the person who posted this must have access to it.

I kinda want one

Hey guys, just bought a hybrid xlt and the first 3 days of owning this pickup I've noticed the same thing, burnt smell inside the cabin, engine idling pretty loud, I have lifted the rear seat to smell the battery and it didn't look like that was it, poped the hood and the smell got much stronger. I also noticed something glowing at the bottom of the engine (sorry guys I'm no mechanic so i can't tell what it was). Took it to the dealership they said could be some new car chemicals burning up, but if doesn't go away by the end of the week, bring it back in. Made a couple videos, hopefully this helps

Yeah, that does not look good.

As an update on mine for this morning, it was -10º F out and took 3 tries to remote start. However, I changed the climate settings to auto the night before and did NOT have the same issues with crazy exhaust and horrible smell. The downside is, the interior of the truck was freezing after 10 minutes of running. Gotta find a happy medium. And @MilMaverick that glowing is super strange and something I would definitely look into. Could be the AUX heat some have mentioned?

 

[KeinoDoggy]

Did you show this to your Ford service dept.? No way should you have something glowing cherry red under your engine! That's downright scary. Guys, is there a way for him to get this to Ford Corporate?
