Max Mobility, LLC is a subsidiary of Permobil, Inc. Max Mobility was acquired by Permobil in 2017. Max Mobility is named in communications about this recall because it is the official establishment name on record with the U.S. FDA and associated with the SmartDrive MX2+ Power Assist medical device.

The SpeedControl Dial is a wired component of the SmartDrive MX2+ Power Assist Device. The SpeedControl Dial connects to the SmartDrive MX2+ motor and is a rotary controller that allows a user to start, stop, and control the speed of the SmartDrive MX2+ Power Assist Device.

Due to safety and performance issues that have been identified in the SpeedControl Dial, Max Mobility/Permobil has decided to remove it completely from the market.

All SpeedControl Dials are impacted by the issues. Specific part numbers associated with SpeedControl Dials are listed below:
• MX2-3DC (SpeedControl Dial shipped as an independent component/spare part)
• MX2-3DCK (SpeedControl Dial shipped in conjunction with a SmartDrive MX2+ Device)
• MX2-3DCMC (SpeedControl Dial shipped after the first market action/recall was initiated)

No. While investigating a new complaint received during the existing/prior recall, Max Mobility/Permobil identified a design issue that can lead to performance issues with the SpeedControl Dial. Since the design issue has been part of the SpeedControl Dial since its introduction to the market in April 2022, Max Mobility/Permobil made the decision to recall all SpeedControl Dials out of an abundance of caution. This is a new recall that applies to all SpeedControl Dials, including those that were shipped as replacements under the existing recall.

Yes. Max Mobility/Permobil strives to ensure the quality of our products and safety of our end users as our top priority. Since the SpeedControl Dial has already been subject to recall and the newly identified design issue impacts all units, Max Mobility/Permobil has voluntarily decided to fully withdraw the SpeedControl Dial from the market out of an abundance of caution.

No. We are voluntarily issuing this recall and the U.S. Food and Drug Administration has been notified of this action.

1. Immediately discontinue use of the SpeedControl Dial to reduce the likelihood of a potentially
hazardous or harmful situation.
2. Use an alternative method to control the SmartDrive MX2+ Power Assist Device. Alternate
controls include:

optional Buddy Button
• Wirelessly through the SmartDrive MX2+ App utilizing an Apple iWatch or Samsung
Galaxy watch

• 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.
