A software problem is bricking some early Mustang Mach-Es

Charging is a standard concern with electrical automobiles. However some house owners of the brand-new Mustang Mach-E have run right into a peculiar problem: their electrical SUVs received’t begin even when the primary battery pack is full.

That’s as a result of, GadgetClock has realized, there’s a problem with some early Mustang Mach-E SUVs that includes how the a lot smaller 12-volt battery will get charged. It’s the newest in a rising line of small points which have come to mild throughout the rollout of Ford’s first long-range electrical automobile.

As is the case in different electrical vehicles, the Mustang Mach-E retains its 12-volt lead-acid battery topped up by basically sipping energy from the a lot bigger lithium-ion battery pack. Primarily based on house owners’ accounts throughout a number of discussion board threads, together with one who spoke to GadgetClock, the problem is this stops taking place every time the Mustang Mach-E is plugged in to cost up the bigger battery pack.

That is particularly a problem for house owners in areas with chilly climate, as Ford encourages them to depart their Mustang Mach-Es plugged in so the SUVs can use energy from the grid to heat up earlier than driving.

The 12-volt battery powers most of the Mustang Mach-E’s programs (for the reason that bigger battery pack is high-voltage), and so when it dies, the electrical SUV can’t be began. When this occurs, house owners have reported the FordPass app says the automobile is in “deep sleep” mode. Some discussion board members have began referring to it because the “electrical brick” problem.

Ford not too long ago filed a technical service bulletin with the Nationwide Freeway Site visitors Security Administration that confirms the problem has to do with the software on the powertrain management module. Ford wrote that this solely impacts Mustang Mach-E SUVs constructed on or earlier than February third, which means it’s doable that dozens are affected. (Ford would solely say {that a} “small quantity” of the almost 7,000 Mustang Mach-Es delivered within the first three months of the 12 months have the difficulty.)

Proper now, these house owners can’t get the repair through an over-the-air replace. The corporate mentioned in a press release that they’ll must convey their Mustang Mach-Es to a supplier:

We’re conscious {that a} small variety of Mustang Mach-E house owners have had their 12V battery attain a low voltage situation. We proactively labored with early house owners experiencing this subject to establish the foundation trigger and a repair. Within the uncommon cases the place this nonetheless happens, prospects can now contact their native EV-certified Ford supplier to have the matter resolved.

Ford did inform GadgetClock that the problem can be fixable through wi-fi replace “later this 12 months” and that Mustang Mach-Es presently coming off the road shouldn’t be affected.

It is doable to leap the 12-volt battery, simply as you’d jump-start an inner combustion automobile. But it surely’s not almost as easy, particularly as a result of the battery is situated behind the Mustang Mach-E’s entrance trunk, and the hood’s digital latch is powered by the low-voltage battery.

To first open the entrance trunk then, house owners must open a panel within the entrance bumper that comprises two leads, which can be utilized to leap the entrance trunk’s digital hood latch. Then they’ve to drag again a panel beneath the hood to search out the battery — although even at this level, some house owners have had bother accessing the leads on the 12-volt battery and have needed to reduce by the vinyl to jump-start the battery.

Ford provides free roadside help with the Mustang Mach-E, too, so house owners have this as an choice if they should get their electrical SUVs towed to a supplier. The roadside help is additionally supposed to incorporate 12-volt battery leap begins, in keeping with the proprietor handbook.
