Modifying a Ford Mustang with a supercharger kit certainly improves acceleration, but according to a new recall, it may lead to acceleration when you don’t want it. A new recall issued by the National Highway Traffic Safety Administration reveals that the Ford Performance M-6066-M8800 Whipple aftermarket supercharger kit for 2024-2025 Mustang GT and Mustang Dark Horse vehicles has a fault that could disable functional safety features, potentially resulting in “unintended acceleration or unintended vehicle movement.” Naturally, the supercharger itself is not at fault; the powertrain control module is to blame with a software error that may disable functional safety features.
At Least The Recall Is Relatively Small
Ford
According to the recall report, 1,048 supercharger upgrade kits are potentially affected by an updated powertrain control module that incorrectly disabled Level 2 functional safety features. More specifically, the software removes the safeguards that should come into effect if there is a throttle actuator fault (such as the throttle getting stuck open), and this could increase the risk of a crash. Although not necessarily the case with all affected vehicles, some owners may notice a Malfunction Indicator Lamp or wrench light in the cluster, providing some warning of the possible issue.

The problem was first noted during sign-off testing on August 20, 2025, and three days later, Ford Performance Parts stopped the sale of these upgrade kits. Fortunately, Ford has not been made aware of any warranty claims, field reports, accidents, injuries, or fires relating to this issue, and there has been no need to recommend that owners stop driving their vehicles. Still, this is quite a worrying issue for a kit that boosts outputs to as high as 810 horsepower and 615 lb-ft of torque, not to mention something that costs $10,500 on the Ford Performance Parts website.
A Fix Is Coming Next Week
Ford
As always with a safety recall, Ford will address the issue at no cost to customers, and dealers have already been notified alongside owners, with a remedy notification expected to go out from October 27-31, roughly a week from now. Frustratingly for the automaker, and although this recall only affects a small number of buyers, this is yet another blemish on Ford’s reliability record after some 625,000 cars were recalled for a fire risk last week and another 1.9 million vehicles were recalled the week before over failing rearview cameras. CEO Jim Farley said earlier this month that Ford’s powertrain durability is now competitive with that of Toyota, but with various problems continuing to result in major recalls across the product lineup, it’s hard to believe that things are improving at the Blue Oval. Maybe 2026 will be a better year for Ford’s reliability reputation.
