Mustang Mach-E has a battery issue that prevents it from running

Charging is a common concern in electric cars, but some owners of the new SUV Mustang Mach-E have encountered the strange problem of the car not running even when the main battery pack is full.

The reason has to do with a problem with some early Mustang Mach-E cars that involves how to charge the battery at 12 volts.

The problem is the latest in a growing series of small issues that emerged during the introduction of the first long-range electric vehicle of the a company Ford.

And just like in other electric cars, the Mustang Mach-E keeps its 12 volt lead-acid battery full by essentially getting power from a much larger lithium-ion battery pack.

And judging by car owners, the problem is that this stops happening when the Mustang Mach-E is plugged in to charge the larger battery pack.

This problem is specific to vehicle owners in cold weather regions Encourage them Ford is on leaving the Mustang Mach-E plugged in so the car can use power from the grid to warm up before driving.

The 12-volt battery powers many of the Mustang Mach-E systems, given that the larger battery pack has a higher voltage.

This means that when there is a problem with the 12 volt battery, the electric vehicle cannot start, and the owners have reported that the FordPass app says: The car is in deep sleep mode.

And Ford recently introduced Technical Service Bulletin To the National Highway Traffic Safety Administration confirm that the problem is with the software across the powertrain control unit.

Ford writes that this affects Mustang Mach-E cars built on or before February 3rd only, meaning that about 7,000 vehicles delivered in the first three months of the year are likely to be affected.

These owners cannot obtain repair via a remote update at this time, and the company said in a statement: The owner is obliged to bring the car to a dealer.

We are aware that very few Mustang Mach-E owners suffer from this issue, and we have worked proactively with the first owners who encountered this issue to identify the root cause and fix it, and in the rare cases where this continues to happen, customers can contact their local authorized Ford dealer, ”the company added. to solve this problem.
