Ford Mustang Mach-E Safety Issue Prompts Stop-Sale Order

Back in May, FoMoCo recalled select 2021 Ford Mustang Mach-E all-wheel drive models over an issue with unintended acceleration, deceleration, and/or a loss of power. In affected vehicles, those problems were caused by the powertrain control module (PCM) functional safety software, which may fail to detect a software error. Now, The Blue Oval has also issued a stop-sale on the Ford Mustang Mach-E due to a potential issue that could cause certain examples to become immobile, according to CNBC.

The issue – which was outlined in a letter sent to dealers this week – affects around 49,000 of roughly 100,000 2021 and 2022 Mach-Es produced thus far, or more specifically, those built between May 27th, 2020 and May 24th, 2022. Ford has reportedly submitted a recall petition to the National Highway Traffic Safety Administration (NHTSA) as well.

The problem related to this stop-sale and pending recall stems from the Mach-E’s high-voltage battery main contractors – a power circuit’s electrically controlled switch – which can overheat, leading to a malfunction that can cause the EV crossover to not start or immediately lose power while the vehicle is moving.

For now, there is no fix for this issue, though one is expected to be in place by the third quarter of 2022. Ford notes that it is preparing a software update for the Mach-E’s Secondary On-Board Diagnostic Control Module and Battery Energy Control Module that can be installed either over-the-air or with a visit to any Ford dealership. Affected Ford Mustang Mach-E owners are expected to be notified when this fix is ready by mail, at which time dealers will have repair instructions and parts ordering information provided to them.

    This Mach E launch just keeps getting worse. This is the 4th recall on the Mach E in less then 2 years. I was just thinking about looking at the Mach E and maybe buying one, because the dealer around the corner has 3 of them sitting on his lot, but cannot now, because of the stop sale, and again it is making me question whether this technology is safe to buy.

      The blind Executive team put a Mach-E GT with 480HP. One of the 2 causes of the SALES STOP ORDER was the battery overheats when people race their cars when every possible.
      So a thinking person might ask What Models of the Mach-E’s experience this issue? If the numbers are slanted to the GT with very few Select, Premium and California being involved; a smart Executive would help their Dealers and Valuable Customers and address the models with the issue.

    Many of the items you listed can also fail on a Mach E. It is a computer on wheels and it will be prone to fail.

    Putin’s fault.

    The Wilderness tire failure is a Good Year issue. Not Ford.

    Ford has a lot to answer for, and then some. But facts are facts.
