A software issue poses a safety hazard.

The NHTSA has issued a recall by Harley-Davidson on three models of trikes that could potentially present a software issue that could cause the rear brakes to activate on their own. Here are the details. 

Harley-Davidson Motor Company has issued a recall on over 12,500 trikes in the United States for a potential brake problem due to a faulty software. The company estimates that roughly one percent of the 12,624 recalled units are actually affected by the problem. The models targeted by this recall are:

  • 2019-2020 Harley-Davidson FLHTCUTG (Classic Ultra Tri Glide)
  • 2020 Harley-Davidson FLHTCUTGSE (CVO Tri Glide)
  • 2019-2020 Harley-Davidson FLRT (Freewheeler)

The three models of Harley trike are equipped with an electro-hydraulic control unit (EHCU) that manages the Trike Traction Control System. The company found that the EHCU could present an error and cause the traction control to respond incorrectly to a faulty rear-wheel speed signal. This could lead to one of the rear brakes to engage on its own and cause the trike to suddenly change direction. The loss of control that could result from it could ultimately cause a crash. 

The Harley-Davidson dealers should already be aware of the issue and letters to the owners affected have been sent at the beginning of December. Owners are invited to make an appointment with their Harley-Davidson dealer to have their trike checked. Should the vehicle present the software issue, the system will be updated which should eliminate the error. The service will be provided free of charge.

Should they have any questions or concerns, owners of one of the models involved in the recall are invited to call the Harley-Davidson customer service line at 1-800-258-2464 to have their VIN verified. The company’s internal number for this recall is 0175. Customers are also welcome to address their inquiries to the NHTSA’s hotline service at 1-888-327-4236.
