What is wrong

BMW of North America, LLC (BMW) is recalling certain 2017-2018 C Evolution motorcycles. The front wheel may splash water onto the electrical plug connection of the DC/DC converter's 12V battery ground cable lug, resulting in corrosion of the electrical contacts.

The risk

Corrosion on the electrical contacts may cause overheating, increasing the risk of a fire.

Why electrical defects matter: Electrical faults can cause a loss of power, disable safety features or, where wiring overheats, start a fire.

The remedy

Dealers will replace the cable section with the ground cable lug with a repair cable kit, free of charge. In addition, the 12V plug connector to the DC/DC converter will be checked; if contact corrosion is found to be present, additional sections of the wiring harness will be replaced, free of charge. Owner notification letters were mailed on July 13, 2026. Owners may contact BMW customer service at 1-800-525-7417. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning July 6, 2026.

About the electrical system

Modern vehicles run on dozens of control modules and miles of wiring; an electrical fault can affect lighting, displays, power or safety systems.

What to do

  1. Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
  2. Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-305.
  3. If you notice burning smells, flickering power or warning lamps, have the vehicle checked before continuing to use it.
  4. Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.

Check by VIN

A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.

Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.

Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
