Multiple Codes and Dealership Trust...

[K4fxd]

I called a local dealer and asked what the price was to reflash the PCM. Was quoted $100.00

Tony,

Here are some documents from the service manual pertaining to each DTC. I hope this helps you make an educated decision moving forward. I think Cobra Jet nailed it, as much as you can with the limited info available.

The problem is that the pinout tests suggested by each DTC are very complex. If you wish to troubleshoot it yourself, then I suggest you buy a copy of the service manual. IIRC, they are a little over a hundred bucks, but if you are going to keep the car, you really should invest in it. I was going to copy all the pinout tests, but it is too much data and too complex. They are dependent on the results of previous steps (like a decision matrix).

Good luck.

I would let them fix the P2020 under warranty, argue about the PCM programming, and probably tackle the rest of it myself.

Tony, I wish I could add to this but looks like everyone beat me to it, Great advice guys! Dealerships sure are getting creative these days to rip off there customers.
I really hope you get it all covered under the powertrain man, sounds like it should be.

Thank you for replying brother. I appreciate the kind words and support. I'll post an update later in the week to let everyone know how bad I got bamboozled.

Maybe time to call zach@granger and get that extended warranty

I believe you can buy a warranty after the mfg warranty expires, but the car will have to undergo an inspection. I think the cost is more expensive after the fact as well.

I'd be taking it to a different dealer, honestly (if there's one nearby)... even if you just get the warranty stuff fixed, don't let these jerks get paid by ford.

If I do that and walk away, I have to pay them the diagnostic fee. I'll have to talk to them on Monday and see what's what. Thanks for your input. It does get distasteful when a service department pumps up the bill.

I wouldn't pay the diagnostic fee either, call Ford corporate and file a complaint.

Thank you to everyone who contributed to this issue. I ended up asking them to just do the warranty work (intake manifold replacement) and told them I'd pay for the PCM reprogram. Amazingly the Grille Shutters fixed themselves. They also lowered the price of the reprogram. So the bill went from $2,282.00 to $326. I'll take it to have no check engine light, no codes, and a smoothly running car. I might write the service department about that PCM as it's part of the Powetrain but I've got a life to live. Again, thanks everyone for the support. Mustang6g

MG6 - score!
Dealership - doesn't get all the $$$$

Nice! And to think some people would end up forking over nearly $2,300 because they wouldn't have the insight found here.

@Cobra Jet @honeybadger @Tomster @shogun32 @Houston Kid @Ewheels @The Chairman @Bikeman315 @ChitownStang
@rxsamg @Seanuf99 @Epiphany and anyone else that can intelligently chime in, please do...

My 2018 GT car's check engine light went on and my Fordpass logged 5 different "Service Engine Soon" warnings all at the same time:

1: Detected a Misfire and the start stop feature (if equipped) could be disabled when this fault is present

2: Engine Control System Detected one of the temperature sensors are not agreeing with another, could effect start stop feature and be disabled

3: Engine Control System has Detected the Intake Manifold Runner Control Valve not operating as expected

4: Engine Control System has Detected Lower than expected reading from intake Manifold Runner Control Sensor

5: Powetrain control system has Detected that it is unable to fully open the active grille shutters

So I drop it off at the dealership, and they send me this via text:

The intake Manifold is covered under warranty. But the active grille shutters, and the PCM all going together seems like a lot of problems in one fell swoop. The Fordpass app clearly told me the shutters faulted so I don't think the dealership is inventing problems.

My question is, would you guys have them do everything they are suggesting in this estimate and just eat it? I'm inclined to have them do the Manifold warranty work and the PCM only. Then either do the shutters myself, or see if it corrects itself after the Manifold and PCM are fixed. I believe the active grille shutters aren't a huge issue and can even be disabled or removed from what I've read. $1500 seems to be a lot of that issue.

Of course my warranty expired in April and I didn't extend it because I don't abuse the can and maintain it properly. Maybe time to call zach@granger and get that extended warranty.

Looks like a rip to me. PCM and intake is likely the only issue. Get a set of shutters at the junk yard for $30. (I doubt they are broken).

Have them do the reset and intake manifold. I would not pay for those shutters.

I didn't see this before my response.
