Bad software is turning some Mustang Mach-Es into ‘electric bricks’

Charging is a common worry with electrical vehicles. But some owners of the model-new Mustang Mach-E have operate into a peculiar problem: their electric SUVs will not begin even when the main battery pack is comprehensive.

That’s simply because, The Verge has realized, there’s a issue with some early Mustang Mach-E SUVs that requires how the a lot smaller 12-volt battery gets billed. It is the hottest in a escalating line of little difficulties that have arrive to light for the duration of the rollout of Ford’s initially prolonged-selection electrical car or truck.

As is the circumstance in other electric powered autos, the Mustang Mach-E retains its 12-volt guide-acid battery topped up by basically sipping energy from the a lot greater lithium-ion battery pack. Dependent on owners’ accounts across several forum threads, like a single who spoke to The Verge, the issue is this stops happening each time the Mustang Mach-E is plugged in to demand up the greater battery pack.

That is especially an difficulty for homeowners in locations with chilly weather, as Ford encourages them to go away their Mustang Mach-Es plugged in so the SUVs can use ability from the grid to warm up prior to driving.

When this transpires, owners have documented the FordPass app says the vehicle is in “deep sleep” method. Some forum members have begun referring to it as the “electric brick” challenge.

Ford lately filed a complex services bulletin with the Countrywide Freeway Website traffic Security Administration that confirms the issue has to do with the software program on the powertrain management module. Ford wrote that this only affects Mustang Mach-E SUVs constructed on or right before February 3rd, indicating it’s possible that dozens are influenced.

We are informed that a tiny amount of Mustang Mach-E entrepreneurs have experienced their 12V battery achieve a lower voltage affliction. We proactively worked with early proprietors suffering from this challenge to recognize the root bring about and a resolve. In the exceptional cases the place this continue to takes place, shoppers can now contact their regional EV-qualified Ford vendor to have the matter settled.

Ford did inform The Verge that the problem will be fixable by way of wi-fi update “later this year” and that Mustang Mach-Es presently coming off the line should not be influenced.

It is feasible to leap the 12-volt battery, just as you would bounce-get started an internal combustion car. But it’s not just about as uncomplicated, particularly simply because the battery is found at the rear of the Mustang Mach-E’s front trunk, and the hood’s digital latch is powered by the reduced-voltage battery.

To first open up the front trunk then, homeowners have to open a panel in the front bumper that contains two potential customers, which can be applied to jump the entrance trunk’s digital hood latch. Then they have to pull back a panel beneath the hood to come across the battery — while even at this issue, some proprietors have experienced hassle accessing the prospects on the 12-volt battery and have minimize by means of the vinyl to additional conveniently leap-commence the battery.

Ford gives free roadside assistance with the Mustang Mach-E, much too, so homeowners have this as an solution if they need to get their electric powered SUVs towed to a dealer. The roadside support is also meant to involve 12-volt battery leap begins, in accordance to the proprietor guide.
