ON CERTAIN MOTORCYCLES, THE THROTTLE LINKAGE CAN FAIL TO RETURN TO A COMPLETELY CLOSED POSITION.
Consequence: SHOULD THIS FAILURE OCCUR, THE MOTORCYCLE COULD FAIL TO DECELERATE WHEN THE RIDER WANTS IT TO, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE THROTTLE RETURN CABLE. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING OCTOBER 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT MOTO GUZZI AT 1-678-238-0902.

Reported: 2019-07-26 (July 26, 2019) · Model years: 2017, 2018
Piaggio Group Americas. Inc. (Piaggio) is recalling certain 2016-2018 Moto Guzzi Audace 1400 and Eldorado 1400, 2017-2018 Moto Guzzi California 1400, 2017 Moto Guzzi MGX 21 Bagger, 2013-2014 Aprilia Mana 850, 2014-2016 Aprilia Dorsoduro 750, 2018-2019 Aprilia Dorsoduro 900, and 2018 Aprilia Shiver 900 motorcycles. Due to a problem with the front brake master cylinder, the front brakes may drag or apply, causing the motorcycle to unexpectedly slow down or stop completely without activating the rear brake light.
Consequence: Unexpectedly slowing down or stopping while driving with no warning to following traffic can increase the risk of a crash.
Remedy: Piaggio will notify owners, and dealers will inspect, and if necessary, replace the front brake master cylinder free of charge. The recall began August 16, 2019. Owners may contact Piaggio customer service at 1-212-380-4433. Piaggio's number for this recall is PA2ZZQ1904.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
