2012-2013 Nissan Altima
The Problem: On some Nissan Altima models, a tool used at Nissan’s plant in Canton, Mississippi, to torque certain power steering rack bolts may not have applied the correct amount of torque. Over time, those bolts can come loose and start rattling. If they eventually fall out, the driver may lose the ability to steer the vehicle. Nissan discovered the problem during a routine driving evaluation of a new car.
The Fix: Nissan dealers will check the torque levels of the affected bolts and tighten them if necessary.
Number Of Vehicles Potentially Affected: 8420 2012 Nissan Altima models, and 5499 2013 Nissan Altima sedans.
2012 Mercedes-Benz E350, E550 Coupe
The Problem: The right-side curtain airbag may not have been stitched properly, which could allow it to deflate too quickly after deploying in an accident. That could reduce the amount of protection the airbag offers to occupants during a crash.
The Fix: Starting in November, Mercedes-Benz dealers will begin replacing the right-side curtain airbags.
Number Of Vehicles Potentially Affected: 499 2012 Mercedes-Benz E-Class coupes.
2012 Maserati GranTurismo, Quattroporte
The Problem: A software error may prevent the tire-pressure monitoring system from warning the driver when the tires are underinflated. This could allow the owner to inadvertently drive on underinflated tires, increasing the risk of accident.
The Fix: Maserati plans to reprogram the TPMS computer for free beginning in November.
Number Of Vehicles Potentially Affected: 485 2012 Maserati GranTurismo, GranTurismo Convertible, GranTurismo MC, and Quattroporte models.
