The issue in question is related to the battery positive cable for the alternator and starter motor, the insulating cap of which may not have been installed correctly. The cable may not have been secured properly in the engine bay, too. According to the statement below from the National Highway Traffic Safety Administration, the problem could increase the likelihood of the cable shorting out, causing the wiring harness to overheat and potentially start a fire, or the engine to stall and potentially cause the vehicle to crash.
The expanded recall still only affects certain examples of the 2014 Maserati Quattroporte GTS with the V8 engine – namely those manufactured between October 1 and December 31, 2013. That now includes an estimated 984 vehicles in the United States, the owners of which can expect to hear from their local dealer to have the cable inspected and, if necessary, replaced.

Maserati North America, Inc. (Maserati) is recalling certain model year 2014 Quattroporte GTS V8 vehicles manufactured October 1, 2013, to December 31, 2013. In the affected vehicles, the battery positive cable for the alternator and starter motor may not have its insulating cap installed properly at the starter motor. Additionally, the cable may not be adequately secured in the engine bay. These factors may result in the cable shorting to ground.
If the battery positive cable shorts to ground, the wiring harness may overheat, resulting in a fire. The car also may stall, increasing the risk of a crash.
Maserati will notify owners, and dealers will inspect the vehicle to verify that the starter motor cable has a properly installed protective cap and that the cable is adequately secured. If not, the starter motor cable assembly will be replaced. These repairs will be performed free of charge. The recall is expected to begin November 11, 2015. Owners may contact Maserati customer service at 1-201-816-2600. Maserati's number for this recall is 279.
