ANTIOCH, Tennessee—Max Mobility/Permobil announced a recall of the SpeedControl Dial, a wired control option for the SmartDrive MX2+ Power Assist Device, due to safety and performance concerns. This voluntary action applies to all SpeedControl Dials manufactured and distributed between the dates of April 25, 2022 to July 08, 2025.
According to the Food and Drug Administration (FDA), a Class I recall was originally initiated on Dec. 20, 2024 to address a material change with the printed circuit board assembly (PCBA) in SpeedControl Dials manufactured and distributed between the dates of Aug. 17, 2023 and Nov. 21, 2024. The recall was later expanded on March 28, 2025, and included all units manufactured and distributed from Aug. 17, 2023 up to March 10, 2025. Max Mobility/Permobil reported it received 781 complaints associated with PCBA design. Of these complaints, five were for serious injuries, involving fractured or broken bones and a concussion.
This new expanded recall supersedes the previous recall and applies to all SpeedControl Dials in the market, including replacements received under the previous recall.
Max Mobility/Permobil said it was able to identify a design issue with the SpeedControl Dial that may lead to unexpected behavior of the SmartDrive MX2+ motor. This design issue has been part of the SpeedControl Dial since it was first introduced to the market in April 2022 and impacts all SpeedControl Dials manufactured and distributed, which occurred between April 25, 2022 to July 08, 2025, if there is an intermittent electrical connection between the SpeedControl Dial and SmartDrive MX2+ motor, the following performance issues could occur:
- Continued drive: The SmartDrive MX2+ Power Assist Device fails to fully stop when the SpeedControl Dial is pressed inward.
- Involuntary movement: Unintended activation of the SmartDrive MX2+ motor without intentional user input to the SpeedControl Dial while the dial is at zero position and dial light is flashing in stand-by-mode.
Max Mobility/Permobil has identified 54 complaints that may be associated with this issue. Of these complaints, two involve serious injuries related to bone fractures.
Max Mobility/Permobil has suspended distribution of the SpeedControl Dial, and the SpeedControl Dial is no longer an available control option for the SmartDrive MX2+ Power Assist Device. However, the SmartDrive MX2+ Power Assist Device is not impacted by this recall and can still be used with alternative control options.
Max Mobility/Permobil will replace SpeedControl Dials with an alternate control. The wired SwitchControl can be ordered with a mono jack port to connect with an optional Buddy Button. The Buddy Button is a third-party accessory option, provided by through Permobil, which is a switch that provides further tactile feedback and is larger than our standard SwitchControl. The SmartDrive MX2+ Power Assist Device can also be controlled via an app using a wearable device.
