Harley-Davidson has learned that the software in the Onboard Charging (OBC) System of the LiveWire (ELW) model motorcycles built between 3/18/2019 and 8/20/2020 may initiate a shutdown of the electric vehicle powertrain, without providing reasonable indication to the rider that a shutdown sequence has been initiated.

In some cases, the vehicle may not be able to be restarted or, if restarted, may shortly thereafter shut down again. Unexpected loss of propulsion of the vehicle while in motion without the ability to restart or remain restarted may increase the risk of a crash.

In addition, prior to loss of propulsion indicator lamps may illuminate to include: the Traction Control (TC) lamp, the Anti-lock Brake System (ABS) lamp, and the Failure Indicator Lamp (FIL).

Details of the recall are as follows:

NHTSA Campaign Number 20V624000 — Harley-Davidson Motor Company Components ELECTRICAL SYSTEM

Loss of Propulsion: An unexpected loss of propulsion without the ability to restart may increase the risk of a crash.
Potential Number of Units Affected 1012

Summary
Harley-Davidson Motor Company (Harley-Davidson) is recalling certain 2020 LiveWire (ELW) motorcycles. The electric vehicle powertrain may unexpectedly shut down and not restart, due to a software issue in the Onboard Charging (OBC) system.

Remedy
Harley-Davidson will notify owners, and dealers will update the OBC software, free of charge. The recall began October 19, 2020. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Harley-Davidson’s number for this recall is 0176.

The Service Bulletin is: M1519: RECALL 0176 – LIVEWIRE – SOFTWARE UPDATES

Harley-Davidson ($HOG) is recalling certain 2019-2020 Trike motorcycles built between 3/12/18 and 11/5/19 with traction control.  The Trike Traction Control System software may respond incorrectly to a faulty rear WSS (Wheel Speed Sensor) signal by activating one of the rear brakes. Unintended activation of one rear brake could lead to an unexpected change in the vehicle direction which may increase the risk of a crash.

The potential number of units affected is 12,624.  The component manufacture is Robert Bosch LLC.

The remedy is for dealers to update the traction control system software, at no charge to the customer.  The recall began December 2, 2019. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Harley-Davidson’s number for this recall is 0175.  Specifically, the new Electro-hydraulic control unit (EHCU) software download removes or disables the software from recalled component, that causes this unintended activation of a rear brake.

#9 – Traction Control Switch

Affected Vehicles:
FLHTCUTG         ’19-’20
FLHTCUTGSE     ’20
FLRT                 ’19-’20

IMPORTANT: Should riders choose to ride the motorcycle before this safety recall service has been completed, to reduce the risk associated with this condition, the motor company recommends that riders disable traction control on the motorcycle BEFORE each ride per the following procedure:

1. Start motorcycle, but do not begin moving. (Note: The (TC) icon in the tachometer will be flashing.)
2. Press and hold the (TC) button on the left hand control until the (TC) icon remains illuminated (solid) in the tachometer.
3. Do not touch the (TC) button during vehicle operation.

ABS Module (EHCU) (behind right side cover)

Since the system resets with every ignition switch cycle, this procedure needs to be performed at the beginning of every ride until the safety recall service has been completed.

NOTE: While the Traction Control function will be disabled, this does not affect other functions of the Reflex Defensive Rider System (RDRS). Reflex-Linked Brakes with Cornering-Enhanced ABS and Drag Torque Slip Control systems will remain operational.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Nobody ever thinks it will happen to them or their systems.

I’m talking about building a digital defense and cybersecurity vulnerabilities.

Heads up Harley-Davidson!  The more connected motorcycles become, the more likely they are to get hacked.  Each new “connected” motorcycle feature introduces greater complexity, and with complexity inevitably comes vulnerability.

Motorcycle enthusiasts have spoken and Harley-Davidson listened.  Riders want increased connectivity not simply for productivity’s sake, but also for convenience.  It’s easier to, for example,  interact through the head unit and display an interactive map as the motorcyclist drives towards their destination, versus putting the address into the user’s cell phone’s app and trying to watch the map on the phone and drive.  So, riders use apps for Android and iPhone (Apple CarPlay), that leverage the smartphone for the head unit (HU) display.

At what point does the motorcycle become a data center on two-wheels?  Any part of the motorcycle that talks to the outside world is a potential inroad for attackers. And malicious actors have been incredibly productive, creating immense numbers of threats world-wide.

Do you think I’m ‘inflating’ this out of proportion?

Car versus motorcycle hacking makes great headlines and let’s take a look at a few recent vehicle examples: a moving Tesla Model S is hacked and the hacker remotely controls the brakes (Tesla was forced to develop and distribute a software update to resolve); a Jeep Cherokee was remotely accessed via the UConnect entertainment center from a laptop miles away and disabled it’s transmission (Fiat Chrysler, was forced to recall 1.4M vehicles); a 100M Volkswagen vehicles can be unlocked by hacking the signals from their keyless entry fobs; and then there was Hyundai’s Blue Link, a cell phone application for users to interact with their vehicle.  Users are able to lock, unlock, start and stop the air conditioning or heat, and start the vehicle from a remote location. In addition, the app allows for stolen vehicle recovery and vehicle health reports to be emailed to the user and other parties for scheduling service etc.

SOUND FAMILIAR?

Consider that earlier this year the Harley‑Davidson™ App and the H-D™ Connect service launched which allows owners to connect remotely to select 2020 Touring and LiveWire motorcycles.  The H-D Connect service provides cellular connectivity that can link a Touring and LiveWire owners with their motorcycle through their smartphone using the Harley-Davidson App. H-D Connect allows owners to connect remotely to their motorcycles and allows for viewing of key vehicle health information as well as stolen vehicle recovery and other parties for scheduling service etc.

A computerized motorcycle’s main defense against hacking used to be the fact that all of its systems were separated from any network. But with the rise of telematics systems, connected apps, and onboard WiFi, that’s no longer the case. Harley-Davidson owners now face similar security issues to computers or smartphones and, like those devices, “ironclad” software is the main line of defense and will be as susceptible to attack, just as the user’s home and office PC are.

I’ve previously posted about the larger Internet of Things (IoT). Basically, this means everything in your home that connects to the world wide web. Smart TVs, digital assistants, smart watches, fitness trackers, home security devices, thermostats, refrigerators, and even light bulbs are all on the connected list. Add to that all of the fun stuff: remote-controlled robots; games and gaming systems; interactive dolls; and talking stuffed animals … the list is endless.

And now we have connected Harley-Davidson motorcycles.  What do all of these have in common?   They send and receive data.  The essence of the Harley-Davidson digital transformation is interconnectivity. Interconnectivity is about more than the connections between devices — it is about the connections between customers, partners, and suppliers.  But, do you know how that data is collected, where it is stored, for how long and where it is going?

It’s not clear how serious Harley-Davidson takes the threat of potential cyberattacks on their motorcycles. Given the concerns of hackers doing a “drive-by” on your digital life and the number of malicious actors I’d like to see more transparency from them in regards to motorcycle digital defense — or we risk ending a road trip before it really begins.
