It feels my truck is just falling apart at this point..

Yes I said I have one on back order, but in the midst of having them place one on back order, the engine began misfiring, and is still doing it. They proceeded to tell me to keep driving it until it comes in, and they said March. I’m no vehicle professional, but when a car starts misfiring, why would you keep driving it? Seems odd. And not the PCM isn’t working correctly with body control modules. It’s one issue after the next with this exhuast issue. You tell me what’s the best course of action, because I know you wouldn’t keep driving it correct?

PCM losing communication with BCM is probably a wiring issue. The other thing you posted about the exhaust "Exhaust Heat Exchanger Exhaust Bypass Valve "A" Control Circuit/Open", circuit open could also just be a wiring issue. That's telling you that the PCM cannot see this valve. It could be that the valve has failed electrically or be a broken wire between the two. One would hope that the service department actually verified wire continuity before telling you that you need a part that's on backorder if they are in any way competent, but you never know.

As far as the misfire, not all misfires are equal. If the check engine light starts flashing then don't drive it. If you have a completely dead cylinder that's bad. If it just misses a little when the engine is cold and then it goes away that's a completely different situation. Or if some wiring harness issue causes a random misfire that's yet another situation.

It's possible that all three of these issues are from the same wiring harness issue. To me that sounds more plausible than that you have three different issues at roughly the same time on a newish vehicle.

Glad I got a 2023...

I’ve got a 2023 and I just had all those warnings and my truck was at the dealer for over a week. They replaced the dc to dc converter. So far it’s been ok.

Hello there. I would like to see what I can do to assist with your Maverick's engine warnings. To get started, can you please send over a private message with your VIN and the name/location of your local Ford dealer?

Really? They decided to backorder a whole exhuast for my situation. What is the dc converter?

Sounds about right, I don’t think 3 problems would incur at once. It’s more probable that one issue is causing and leading with a domino effect with other CEL’s. As far as I know the dealer told me to keep driving, I’m assuming they related the other CEL’s to the exhuast valve issue.
It seems this is what went down, exhuast valve stuck, led to random misfiring, and now the PCM isn’t working correctly with the BCM’s. I had the engine surge update already, but that was just the high idle rotten egg smell fix.

I’ve had no CEL blink yet, but if you look at my misfire post, i am not sure whether that is the engine misfiring on startup, or if it’s this “rattle” people are having. But I have had the CEL code for random misfiring.

This is the unit that the charger uses to step down the voltage for the 12v battery. Mine stopped working at 780 miles and the 12v battery stop charging. I hope it was a bad part and nothing caused it to be a bad part. Anyways its charging now.

Too many problems just to save some gas costs.

Sadly, the Hybrid should be the more reliable and less prone to problem drivetrain. Typically, the Hybrid drivetrains have been the more 'bullet proof' models with Ford. My brother, a Ford Mastertech x3 for 30 years, when asked told me go with the Hybrid it will be more reliable, yet you don't see anywhere near as many owners reporting issues with the EB2.0 models.

I am so going to take mine on an extended test drive, with multiple drive cycles, once it shows up in maybe 4-6 weeks, before parting with my 3.6R Outback. (Scheduled for production the week of 3/16). Hopefully, they've addressed most of the issues by then via changes in the supply/production line with 2023 models.

More hybrid issues. I'm just keeping mine just in case there's a class action lawsuit I can get a settlement check!

Taking into account emotional damage! Lol! You come out with our dream truck only to be plague with problems!

I know it has to be low cost to make but I would have preferred a solid hybrid engine over the other useless features like lane keeping assist, auto wipers and headlights, auto hold, etc...

I just want a solid hybrid drivetrain and performance like the Rav4 in a truck form!

just turned 6000 miles on my hybrid no problems at all we love it.

I am trading my hybrid in for eco most likely.

Just wait until all those EB's have 50k+ miles on them and the valves don't seat anymore. I think the consumer is about to have a big wake up call about the current Direct Injection system.

Not all EBs have carbon issues but you're correct that if enough do, it will be a mess for ford. Only around town driving and cheap gas will almost guarantee the issue. I use premium from name brand dealers and try to get it out on the highway every now and then. While not a guarantee, I'm not expecting the issue.

 

[Rockingchair]

7k miles on my hybrid. Only issue that I have is that its never parked at home. Wife keeps using it!

 

[JimParker256]

Sold my Maverick back in May of 2022, bought a first gen tacoma with 200k miles instead.

The Maverick spent 4 out of the 6 months I've owned it either broken down or at the dealer.

The Tacoma spent 0 days broken down or at a mechanic/dealer.

Lesson learned, never buy American vehicles. I'd rather get 20mpg and a Truck that doesn't break down.

And my brother who bought a 2020 Tacoma, only to have it spend 5 months in the shop (various issued) swears he will never buy another Toyota (and neither should you, apparently). He currently has a Honda Ridgeline that spent 3 months of its first year of life in the shop during the pandemic. I suppose you should take Hondas off your list, as well... My best friend from work bought a Nissan, and had two CVTs replaced under warranty, only to have the CVT fail again right after she retired and moved from Texas to Nevada. She will never buy another Nissan (and neither should you).

I could go on, naming every brand in existence, but I suspect you get the point. ALL manufacturers can have "bad models" and ALL vehicles can have "bad examples." Heck, I even know a guy who owns a Rolls Royce that was in the shop more than 1/2 of its first year... If you will only buy a model that's never had an issue in its history, from a manufacturer that's never had an issue in their history, you're gonna be waking, my friend...

Good luck!

Maybe in a year or so...
