What is wrong

Piaggio Group Americas, Inc. (Piaggio) is recalling certain 2019-2020 MP3 500 motorcycles. The brake lines may have been improperly galvanized, allowing hydrogen to be released into the brake fluid.

What can happen

Hydrogen in the braking system can reduce the brake lever's ability to activate the brakes, increasing the risk of a crash.

The remedy

Piaggio will notify owners, and dealers will perform a complete brake system flush, free of charge. The recall began September 10, 2020. Owners may contact Piaggio customer service at 1-212-380-4433. Piaggio's number for this recall is PP2ZZQ1904_MP3.

Notes

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 www.safercar.gov.

P_190715_RC_EN	2019-08-03. Service bulletin. Dear Dealer / Service Center, We hereby inform you that, on a specific lot of 2019 MP3 500 LT ABS, it is necessary to perform a technical update by adjusting the brake pedal master cylinder adjuster, in order to restore the correct play between the brake pedal and the master cylinder. Concern: Integral brake pedal master cylinder linkage may have inadequate free play, resulting in residual brake pressure being applied to the rear brake caliper.
