The problem
Maserati North America, Inc. (Maserati) is recalling certain model year 2017 Quattroporte and Ghibli vehicles manufactured July 1, 2016, to October 12, 2016. The rear differential unit pinion nut may not have been properly tightened, allowing the pinion nut to loosen.
The risk
A loose pinion gear may bind, possibly resulting in the rear wheels locking up and increasing the risk of a crash.
The fix
Maserati will notify owners, and dealers will inspect the rear differential unit pinion nut torque, and, as necessary, replace the rear differential unit, free of charge. The recall began on December 30, 2016. Owners may contact Maserati customer service at 1-877-696-2737. Maserati's number for this recall is 328.
