I have a love hate relationship with my Mach-E. My experience yesterday has been by far the worst of the problems I’ve had.
I drive from the Philly area to the Jersey shore pretty frequently, aside from my blue cruise disappearing and having to switch to the “guest” profile to use it, it was a pretty normal drive home. On my drive back to the shore, a wrench and a car with an exclamation point as well as a warning message to service vehicle soon popped up on my display . The car felt like it was driving rough so I pulled into a rest stop to check my app and saw the high voltage battery and failure warning. I had about 30 mins to go and a restless 5 year old in the car so I drove the rest of the way. When I arrived I called the closest Ford dealer but they were booked for diagnostic appointments 3 weeks out and suggested I call roadside. I went down that route (I’ll cut this part short), after a cancelled tow and another company that arrived 5+!hours after the initial tow request, the car is back in PA at our local dealership. I have to rent a car since I’m now stranded in the jersey shore 🤪. My Ford service center has no loaners available due to customers waiting for their cars and back ordered parts. I feel like this debacle is just beginning….
Has anyone had to deal with this issue lately? How long did the fix take? I saw some posts but they weren’t all that recent.

I got mine done back in January, and there were no supply delays then. Based on that and other's later comments I'd say parts won't be the hold up for you. Slow dealer service, lack of trained techs, inability to keep appointments, etc are more likely to be a headache for you.

The good news is it's a lot easier to harass your service dept than it is to speed up parts production.

Try scheduling with a different dealer.

You're not stranded, the power limit makes the car slower but you can still drive the car until your service appointment. It's like a check engine light.

This /\

If this is actually the HVJB issue the car is still drivable. I drove mine for almost a month (dealer just reset the system the first time) under your current condition.

Unfortunately, no dealers within 30 miles could service the car within a week.

Since it looks like you have recently joined the board and may not be aware of the thread detailing the history, process and repair of the HVBJB, I am attaching it here https://www.macheforum.com/site/thr...ers-biggest-fear-facts-and-info-thread.18143/

While it is important to first have the diagnosis to see what kind of problem the car is currently experiencing (You may find it is something other than a HVBJB), I would start with contacting the BEV team listed in the thread and keep in touch with them as the repair proceeds.

I would also get a case open with Ford’s customer service. I did it by messaging their account on this forum when this happened to me. You will get assigned a service rep who should help expedite parts if needed and be calling and harassing the dealer on your behalf to get the repair done as quick as possible. I know that not everyone on this forum has that good of an experience with their customer service, but I did personally.

They also compensated me a month’s payment on the vehicle at the end of the ordeal. That was back in early 2021 when backordered parts were a huge problem and the car was stuck at the dealer for a month, but it is still worth asking for.

THIS. I got The Warning driving over a high pass in hot weather last weekend and just dropped off the car. It drives ok but has vastly reduced power, like half or less. The throttle seems the same the first 1/3 to 1/2 of travel, then just doesn't deliver any more power the rest of the way down to the floor.

When I dropped it off after making an appointment, the service guy said he's short on staff and it'll be "some days" before they can get to it. I asked if I could schedule for when they can get to it and he said he can't schedule that way.

He also said no loaners available, I said I got one when this happened last year (the first day I had the car), and he said that was sales. He hemmed and hawed and gave non-definitive answers about whether I'd be refunded for a rental if this turned out to be a warranty issue. "Almost always" isn't "yes it will be."

I've had nothing but issues since I purchased my MME GT 2023 12/10/2023.
It's had a dead 12v battery.
It's been in the shop 4 times for a total of 39 business days. 3 of the 4 times was due to Powertrain Malfunction code. The first two times they replaced some wires and parts. I picked the car up last night and they tell me that they cant find anything wrong so they sent me on my way.
I reached out to Ford Corporate last week to start the buy back process. Hoping in the next week I get good news and they will buy the car back. If not I'm going to find a lemon law lawyer.

Certainly the most fun car I've ever owned and driven. Just the most unreliable.

Good luck with your MME!

Welp 12 days in with no resolution, the more research I do the worse this car and the issues look. I think I’m done with my Mach-E, I was such a cheerleader for this car 😞.

Have 1750 miles on my 23 gtpe and the dreaded high voltage warning came up and killed 1/2 the power. Have never fast charged and don’t floor it all the time as I use the car for work. Not very happy that ford hasn’t fixed this issue when the car has been out for 3 years now. Been at the dealer for a few days now

Hi Jim! I can look into your Mach-E's concern on my end. To get started, could you please send a private message over with the name/location of your local Ford dealer and your Mach-E's VIN?
