2021 MachE 60k miles huge problem: VIN changed

[MacherAWD]

Someone had mentioned that it was only roughly $100 but I can’t confirm it.

I agree with you that there are a lot of things that can go wrong with the car. I don’t have any experience with Ford but I do not have a ton of confidence.

Oh, in that case I will probably just wait until year 3 to buy. I think with any new car with this much tech its worth it. Normally if things start to go after year 5 you just deal with it. But I would hate to loose BC or alerts, and other safety tech because a sensor is out of warranty.

Go on the granger ford site to see if there is much difference after 1 year. I just looked and it seemed almost the same. Of course price might go up later

good luck

also I think if car is sold the warranty is refundable , pro rated of course, dependent on your state

If it is electronic data it can be wiped, corrupted and/or modified. Only need access and rights to make changes or have a good EMP.

Well, yes and no. My suggestion was that the write channel be inaccessible by other than a separate physical interface. This would alleviate the possibility of erasing or modifying the data. Reads can take place over the vehicle buses, but no write access to that small portion of storage. I have worked on a lot of components in the old days that had reserved storage for portions of their firmware. It ads cost, but it’s very simple. ??

Good immunity to outside forces should be a given. Immunity should start with the silicon level and end at the system level. Yeah, most silicon and board guys haven’t got a clue, which is why the mechanicals often need to be overkill. ?‍?

Coming up on 1 year now, do you know the price difference if purchased before end of year one, vs end of year 3? I am thinking I will keep the car 8 or more total years so to have all the cameras, software, sensors, and little gadgets covered seems worth it.

What I understood is it is reassessed each year? How much would depend on year and you would need to ask. Not sure if they even will give 3 years in advance or just the up coming year. I waited until the end of the first year and extended to 8 years at purchase cost. First thing since our first microwave from Futureshop. Do not do it too often (ever) but seeing the state of the tech and all the electronic hardware we decided it could be worth the cost?

At this point in the thread it appears that is not the case. I guess if recalls, ota's and fordpass are not required then they are good to go.

Every module that has the VIN coded in it can be changed by Forscan, with the exception of the PCM. Problem is if the VIN doesn't match the PCM, then you'll get DTCs regarding the VIN mismatch. It would be very easy for a ford glitch to push bad as-built data down to a module OTA. Unfortunately, if the Ford Server now has the wrong VIN, then it'll be hard to fix even with FDRS. The server side would need to be fixed first.

Like @Maquis said, legally doesn't matter. If it was a car that didn't have FordPass or OTA capability, it wouldn't even matter honestly. The DTC doesn't even show up without scan tools. But I would definitely push to have them cover the cost, because in this case, the only way it would change would be a push from Ford servers.

We replaced the body control module that didn't fix it. Now we are waiting on fords approval to change the cluster.

Thank you! I’m going to get all the paperwork form the two dealerships service depts this week. I’ll post them, and keep this thread current with information. The easiest way to explain would be to imagine if someone replaced the SIM card on your phone. Sure my phone is still my phone, but internally it’s another number. No one at the dealership can even begin to offer an explanation. One service rep made a joke and asked if the car was hit by lightning.
I have a first edition 21 Mach E took delivery 25 months ago. This first became a problem in July after fixing a recall. After trying to replace one module. I was told they’re waiting on ford to send another one however it wouldn’t be under warranty. That’s when I came here.

I just googled and NYS lemon law is one of the best in the country for consumers. I would not waste any more time and call Ford and tell them you want a buy back for your piece of }^*% car.

Essentially you have to have the problem occur within 24mo and 18k miles, and then they get 3 attempts to fix it. Or you lose use of car for 30 days. Hopefully you qualify for this.

Even if you don't qualify under NYS lemon law I would call Ford and request a buy back. This is a very unique issue that could only be caused by Ford.

Well, replacing a module requires a PMI, and depending on how they're doing it, they are just pulling the data off the old module and putting it right back on the new module.

If they're doing it the right way, they're loading straight from the ford servers. Though, if there's an issue with the data on Ford's servers, then they could also be loading the wrong data on the module.

The dealer is waiting for the ford technical team to come up with a fix. I have a case open etc. waiting to hear from Ford...

 

[kkriskal]

Wow, i didn't even know something like this could happen in a vehicle

I can tell you with a high degree of certainty that those “three computers” that talk to each other and work with your VIN are the GWM, APIM and TCU.

They likely need to be re-provisioned. FDRS has a tool that your dealership can run to re-provision the modules, starting with TCU I believe. That will program the VIN and re-register the car with Ford’s backend servers. As long as the VIN in FDRS is the correct one, that’s the one it should program. Maybe ask them to give that a go.

Thank you for the information. Right now we are waiting to hear back from fords technical team. I have a case open with ford, and once ford technical advises the dealership I'll know more.
