Concerns about charging are frequent with electric vehicles. However, a strange issue has arisen for certain Mustang Mach-E owners: their electrified SUVs won’t even start regardless of whether the primary battery pack is fully charged. This is because, according to information obtained by The Verge, certain early Mustang Mach-E SUVs have an issue with the way the much lesser 12-volt battery is charged. It is the most recent in a string of minor glitches that have surfaced during the launch of Ford’s first long-range vehicle.
Similar to certain other electric vehicles, the Mustang Mach-E draws electricity from the considerably larger lithium-ion battery pack to maintain its 12-volt lead-acid battery. According to user accounts in numerous forum threads, such as one that talked with The Verge, the issue is that when the Mustang Mach-E is plugged in to recharge the bigger battery pack, this stops occurring.
Ford advises owners to abandon their Mustang Mach-Es hooked in order for the SUVs to draw the grid’s power to heat up prior to driving, but that presents a problem for those who live in cold climates. Because a lot of the Mustang Mach-systems E’s are powered by the 12-volt battery, when it expires, the electric SUV will not start. Multiple systems in Mach-E are powered by a 12-volt battery, and the vehicle cannot be launched if the batteries die. Owners claim that perhaps the FordPass app indicates the car is in a “deep sleep” state when the problem occurs. A tech support bulletin that Ford submitted with the National Highway Traffic Safety Administration confirms the problem, which it claims is caused by software problem bricking some early mustang in the power train central controller.
The problem affects Mach-E SUVs manufactured on or before February 3 of this year, according to the tech support bulletin. Ford has not specified the precise number of its electric vehicles that are impacted, merely noting that a “small fraction” of the nearly 7000 units shipped in the first quarter of 2021 have had the problem.
Some Mustang Mach-Es are being turned into “electric blocks” by defective software.
Ford has informed the National Highway Traffic Safety Administration of a technical support bulletin that verifies the issue is related to the system on the power train central controller. Ford stated that the issue only applies to Mustang Mach-E SUVs manufactured on February 3rd or before, which suggests that many may be impacted. These owners are currently unable to receive the repair via an over-the-air update. Along with software problem bricking some early mustang, they must take their Mustang Mach-Es to a dealer, the manufacturer said in a statement:
“We are informed that a limited number of Mustang Mach-E users have experienced low voltage conditions with their 12V battery. We proactively collaborated with initial owners who were having this problem to determine the source and a solution. Consumers can now get in touch with their neighborhood EV-certified Ford dealer to get the issue fixed in the infrequent cases where this still happens.”
The Mustang Mach-E may be jump-started, but this is not a simple process.
Owners must then unlock a panel in the front bumpers that have two leads that can be utilised to bypass the front trunk’s electrical hood latch in order to first open it. The battery would then be accessible by pulling out a panel behind the hood, although even at this stage, certain owners have already had difficulty getting to the 12-volt battery’s leads and also have cut through vinyl to make it easier to jump-start the batteries. In case customers need to have their electrified SUVs towed to a dealer, Ford also provides free roadside assistance only with Mustang Mach-E. Based on the owner’s manual, the roadside help is also meant to cover 12-volt battery jump starts.
FREQUENTLY ASKED QUESTIONS
Q1) The Mustang Mach-E has how many volts?
Ans: The system has a power of about 450 volts DC.
Q2) What transpires if Mach-E runs out of power?
Ans: Whenever the automobile was rescued from the proving ground circuit, it could no longer participate in the drive and needed to be winched. The Mach E exhibited a number of messages to pause & charge, just like the majority of the other electric vehicles used in the test.
Q3) How much time does an electric Mustang take to recharge?
Ans: Range, Battery Size, and Charging Power. Ford claims that the extended-range packs could charge between 10 to 80 per cent in 45 minutes, compared to the standard-range pack’s charging process of 38 minutes.
