Max Mobility/Permobil expands recall of SpeedControl Dial for SmartDrive MX2+

LEBANON, Tenn. – Max Mobility/Permobil has voluntarily expanded its recall of the SpeedControl Dial, a wired control option for the SmartDrive MX2+ Power Assist Device, due to safety and performance concerns. This expanded recall now includes all SpeedControl Dials manufactured and distributed between April 25, 2022, and July 8, 2025. 

Background and prior recalls 

The original Class I recall (Z-1116-2025, Z-1117-2025, RES #96086) was initiated on Dec. 20, 2024, targeting SpeedControl Dials with a material change in the printed circuit board assembly (PCBA) produced between Aug. 17, 2023, and Nov. 21, 2024. It was expanded on March 28, 2025, to include units manufactured through March 10, 2025. Max Mobility/Permobil received 781 complaints related to the PCBA design, including five reports of serious injuries such as fractures and a concussion. 

This latest recall supersedes all previous actions and includes all SpeedControl Dials in circulation, including replacements issued under earlier recalls. 

Reason for expanded recall 

Ongoing complaint monitoring and investigation revealed a design flaw present since the product’s launch in April 2022. The flaw may cause intermittent electrical connections between the SpeedControl Dial and the SmartDrive MX2+ motor, leading to two key performance issues: 

• Continued drive: The motor may fail to stop when the dial is pressed inward. 

• Involuntary dmMovement: The motor may activate unintentionally while the dial is in the zero position and flashing in standby mode. 

Max Mobility/Permobil has identified 54 complaints potentially linked to this issue, including two serious injuries involving bone fractures. 

Health risks 

Users may experience continued drive or involuntary movement, which can result in minor injuries (cuts, bruises, soreness) or serious injuries (fractures) depending on speed and circumstances. There is also a risk to individuals nearby, as the powered wheelchair could unintentionally bump into or run over another person. 

Affected products 

All SpeedControl Dials are affected by this recall. Specific part numbers are: MX2-3DCK, MX2-3DC and MX2-3DCMC.
