Second Ford Mustang Mach-E Lawsuit Filed Over Alleged Battery Defect

Back in June, a recall was issued for the Ford Mustang Mach-E after it was discovered that the EV crossover was experiencing an issue with its battery contractors that could cause certain examples to become immobile. The recall – which also prompted Ford to temporarily halt deliveries – affects 48,924 of roughly 100,000 Mach-Es produced thus far, but the automaker didn’t initially have a fix for the problem. A workaround for the issue recently became available that prevents the EV crossover from “bricking” itself, but a group of owners filed a lawsuit regardless, claiming that Ford knew about this potential design flaw and hasn’t yet figured out how to fix it. Now, a second Ford Mustang Mach-E lawsuit has been filed over this alleged battery defect, too.

This new lawsuit comes from Hagens Berman Sobol Shapiro LLP – the same firm that is also spearheading a lawsuit for 2021 Ford Expedition and Lincoln Navigator owners after a number of those SUVs have caught on fire, prompting a recall but no immediate fix. This new Mach-E class-action lawsuit claims that these vehicles were built with a faulty high voltage main battery contactor “that can reportedly suddenly and unexpectedly cause the vehicle to lose power, disabling the engine and key safety features. The defect presents a high risk of crash, injury, and death.”

The lawsuit – filed in the U.S. District Court for the Eastern District of Michigan – accuses The Blue Oval of “selling Ford Mustang Mach-E vehicles that were dangerously defective and prone to complete and partial shut-down while driving,” as well as knowingly selling the vehicles with this defect and shifting the risk of this problem to owners. The lawsuit is seeking repayment for owners, including out-of-pocket costs and loss of vehicle value.

Ford’s temporary fix for the issue is software only, with no hardware involved, and reportedly ensures that the EV crossover doesn’t brick itself, or stop working altogether. Overheating connectors would instead trigger a service vehicle soon message, protecting them from damage in the process. This means that owners could at least drive their Mach-Es to the dealer for the update in reduced power mode, rather than having to tow the vehicle there. The software update is merely a way to protect the Mach-E’s contactors – not permanently fix the problem.

“At best, Ford’s touted ‘fix’ is seemingly insufficient and ineffective, rendering these cars far from the Mustang name they were given, and at worst, it is only delaying the very likely potential that a sudden shut-off event caused by the Mustang Mach-E defect could cause a fatal crash,” said Steve Berman, Hagens Berman co-founder and managing partner. “Mustang Mach-E owners are reporting terrifying events – complete loss of throttle at full speed on the highway, attempting to pass traffic with sudden total loss of power. We want to see Ford take meaningful action, fast.”

    This is a really bad problem. Coincidentally, after I read about this total EV vehicle shutdown problem on this website, I was passed by a Mach-E on the highway and I was thinking about the article I just read and then BAM! that guy’s Mach-E powered down in the middle of the highway and he limped over to the right side of the road. Lucky for him, there was light weekend traffic. During the weekday, he would have been stuck right in the middle of the highway.

    I had my MME FE brick in the parking lot of a Burger King in March 2021 on Easter Sunday. I won’t go into the hassle this created but Ford did take care of everything and for that, I’m most grateful. I love my car and hope Ford can find a permanent fix for this in the near future before anyone gets hurt.

    Ford desire to remain the recall leader in the auto industry has resulted in more lawsuits and probably lower profits.

      As a lifelong Ford owner (Mustangs, truck), it’s hard to watch how they’re imploding over this unnecessary EV push. 3.3 Million vehicles recalled and counting. Done with Ford due to their new CEO.

    Yep, it’s pretty much over for Ford. Working for a large telco for 50 years, I know a lot about batteries, especially large ones and know well that no battery power connection issue can ever be repaired by software. It was just a LIE that it could.

    Ford’s Net Income is down almost 200% since their pivot to EVs. Toyota refuses to pivot to EVs and they’re down only 34%. America’s are strongly rejecting EVs due to their unreliability, higher repair costs, and the cost to fill them with electricity.
