2021 AWD Rear Drive Motor Failure after 52,000 miles, not covered under warranty (Almost Solved)

[zooka]

I would hope the rear motor is actually part of the eDrive system, which has a better 8-yr, 100k mile warranty. Tesla includes their drive motors in the battery/eDrive system warranty - this seems to be the industry standard (and maybe even a federal requirement under the law that requires 8-yr/100k mile warranties on the battery/high voltage electric systems in EVs - but not certain).

You are correct here the motor is the edrive system, I think there is some misunderstanding in the claim between the dealer and ford.

No idea how ford works but the job could have been submitted wrong, they think there is external damage to the motor causing its failure, ford really did make a mistake, dealer wants to make a buck...hard to know.

2 Weeks ago, our Mach-E went into limp mode and would not move. After towing the car to the dealer and full diagnostics, it was determined that the rear drive motor failed. I later realized I had pink transmission-looking fluid in my garage, which was from the motor.
The motor part number is:
LJ9Z7C629A / LJ9P-7P500-AF

When the service adviser entered the part number in the system, it came back that it was not covered under warranty. I separately called Ford and they confirmed that the rear drive motor is not covered under the 5yr/60k powertrain warranty, nor the 8yr/100k battery/eDrive warranty.

The dealer is baffled as am I. We don't understand why Ford does not consider the rear drive motor part of the powertrain.

The service manager has created an escalation case with Ford to see how they respond.

Has anyone experience anything similar with the drive motor and/or regarding its warranty?

Below is the narrative the tech wrote up in the notes to Ford:

this has to be a miscommunication,, I mean how on earth could a drive motor not be part of the edrive or powertrain.

I found this when searching the ford.com site. I don’t really understand what AI is/does, but seems like it believes the motor is covered.

Tell the Ford dealer to use 7P500 as the causal part base number. LJ9Z-7P500-B is the old number which is covered under the 8yr/100,000 mile warranty. The new number LJ9Z-7C629-A does not show coverage. Their warranty clerk could get it approved with Ford using the 7P500 as the causal part.

This guy is correct. They need to use the generic base part number instead of the VIN specific base part number. 7P500 is the generic base part number which would identify any E Axle for any EV, where as 7C629 is specific to your car (and other similar Mach Es).

If you want the dealer to verify using Ford published documents, tell them to look up the 2024 Parts Coverage Directory on FMCDealer. Pages 33 and 34 have the two relevant part numbers - you mentioned fluid on your garage floor, so they might try and say the axle seal is the causal component. The 7H260 "SEAL ASY-TRANSAXLE DIFFERENTIAL" and the 7P500 "DRV UNT ASY PRIM RR ELE (PDU)" are both covered under the 8 year/100k mile warranty for the Mach E. This is simply a miscommunication between your dealer and the warranty guys.

"Miscommunication" that can be resolved with a few thousand dollars of cash.

Thanks...I will let the dealer know....that makes sense because today the service mgr told me that initially Ford asked them to disassemble the drive motor and provide details on the parts that need to be replaced. He had to tell them that it was an ev motor and ir doesn't have replaceable parts in it like a regular transmission.....

 

[Hubert]

I would call the EV team 1-800-334-4375 and open a case.

I called that EV number. They were useless and even more clueless than the original warranty department, even after I case them the case number submitted.

Sounds like Ford needs to update their covered part list to include the current part numbers. I’ve run into that before. Somebody should go through all the high voltage components on the Mach-E and Lightning and make sure they are entered under the 100k warranty.

Why do you keep going back to the dealer wants to make cash and deny this person's warranty claim because of that? Are you aware that the dealer doesn't just absorb warranty claims at their cost, they charge Ford for the work...

Not 100% sure what you are trying to say, but it is worth noting that dealer service charges much higher labor rates to customers than what Ford reimburses for on warranty claims - as such, non-warranty service is more lucrative, plus they get the markup on the parts.

So what is your recourse?

This is dealership service department 101 for any car brand.
Step 1 "not covered under warranty" but here is the price for us to do it.
Step 2 for the unscrupulous - the slow roll, you can get it fixed right away if you pay us cash, but gee willikers the manufacturer is making us stand on our heads and chug a beer before we can submit this obvious warranty work.
Step 3 "Warranty Work Submitted" please wait a few weeks to months for parts, we swear we're trying as hard as we can.

The op could be living in step 2, I await to see the delay for parts in step 3.

I asked my dealer to deal with the A pillar noise months ago...still waiting for those parts to come in...and that callback....they are sure trying real hard to get them and that's 100% reimbursed by ford.

it's always possible ford is incompetent they might be senile after 100 years as a car company.

The only way I curb my cynicism is if the OP says they have not offered them an invoice to fix it for a cash price, @Hubert
