A software problem is bricking some early Mustang Mach-Es

Charging is a popular worry with electric powered vehicles. But some proprietors of the model-new Mustang Mach-E have run into a peculiar trouble: their electric SUVs will not begin even when the primary battery pack is total.

That’s because, The Verge has learned, there is a challenge with some early Mustang Mach-E SUVs that involves how the a great deal smaller 12-volt battery receives charged. It’s the most up-to-date in a escalating line of smaller challenges that have occur to mild throughout the rollout of Ford’s initially prolonged-range electric automobile.

As is the case in other electric powered vehicles, the Mustang Mach-E retains its 12-volt direct-acid battery topped up by primarily sipping electricity from the significantly larger sized lithium-ion battery pack. Based on owners’ accounts across numerous forum threads, together with one particular who spoke to The Verge, the problem is this stops taking place when the Mustang Mach-E is plugged in to cost up the more substantial battery pack.

That is particularly an challenge for entrepreneurs in places with cold temperature, as Ford encourages them to leave their Mustang Mach-Es plugged in so the SUVs can use power from the grid to heat up just before driving.

The 12-volt battery powers quite a few of the Mustang Mach-E’s programs (considering that the greater battery pack is large-voltage), and so when it dies, the electrical SUV are unable to be started off. When this occurs, entrepreneurs have documented the FordPass app suggests the motor vehicle is in “deep sleep” manner. Some forum customers have begun referring to it as the “electric brick” trouble.

Ford lately submitted a complex service bulletin with the Nationwide Freeway Visitors Protection Administration that confirms the trouble has to do with the program on the powertrain handle module. Ford wrote that this only impacts Mustang Mach-E SUVs designed on or ahead of February 3rd, which means it’s probable that dozens are influenced. (Ford would only say that a “small number” of the almost 7,000 Mustang Mach-Es delivered in the to start with 3 months of the year have the challenge.)

Suitable now, those people house owners are unable to get the repair via an over-the-air update. The company stated in a statement that they’ll have to deliver their Mustang Mach-Es to a vendor:

We are informed that a smaller number of Mustang Mach-E house owners have experienced their 12V battery get to a lower voltage affliction. We proactively worked with early homeowners suffering from this problem to detect the root bring about and a take care of. In the exceptional cases wherever this however happens, customers can now speak to their nearby EV-qualified Ford supplier to have the subject solved.

Ford did inform The Verge that the issue will be fixable by means of wi-fi update “later this year” and that Mustang Mach-Es now coming off the line must not be influenced.

It is possible to soar the 12-volt battery, just as you would leap-start off an inner combustion vehicle. But it’s not approximately as clear-cut, specially because the battery is situated behind the Mustang Mach-E’s entrance trunk, and the hood’s electronic latch is driven by the very low-voltage battery.

To 1st open the entrance trunk then, homeowners have to open a panel in the front bumper that includes two potential customers, which can be used to jump the front trunk’s electronic hood latch. Then they have to pull back again a panel beneath the hood to obtain the battery — nevertheless even at this stage, some homeowners have had difficulty accessing the qualified prospects on the 12-volt battery and have had to minimize by the vinyl to leap-commence the battery.

Ford offers no cost roadside help with the Mustang Mach-E, far too, so homeowners have this as an selection if they need to have to get their electric SUVs towed to a supplier. The roadside aid is also meant to consist of 12-volt battery soar begins, in accordance to the proprietor guide.
