No. While investigating a new complaint received during the existing/prior field action, 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, Permobil made the decision to initiate a field action, removing all SpeedControl Dials from the market out of an abundance of caution. This is an addendum to the field action that applies to all SpeedControl Dials, including those that were shipped as replacements.

Yes. At Permobil we ensure the quality of our products and the safety of our users is our top priority. Since the SpeedControl Dial has already been subject to a field action and the newly identified design issue impacts all units, Permobil has voluntarily decided to fully withdraw the SpeedControl Dial from the market out of an abundance of caution.

No. Permobil are voluntarily issuing this field action and all relevant competent authorities have been notified of this action.
