Driveshaft bolt issue
POWER TRAIN:DRIVELINE:DRIVESHAFT
Nissan North America, Inc. (INFINITI) is recalling certain 2011-2013 M56, 2012-2013 M35 Hybrid, 2014-2018 Q50, Q70 Hybrid, 2014-2019 Q70, and 2015-2019 Q70L two-wheel drive vehicles. The driveshaft can fatigue and break.
Consequence
A broken driveshaft can result in a loss of drive power, or a vehicle roll away when the vehicle is in park without the parking brake applied. Both scenarios can increase the risk of a crash.

What the ratings mean
NHTSA published frontal crash and rollover resistance for this vehicle but not side crash and side pole. An untested area is not a poor result — it means no published data exists, and the overall star rating is calculated without it.
NHTSA's dynamic test put this vehicle's rollover probability at 11.3% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

How this compares
At 19 MPG combined, the 2018 Infiniti Q70 ranks 24th of 24 midsize cars EPA rated for 2018 — 7.5 MPG short of the 26.5 MPG median for that group.
That places it among the thirstiest vehicles in its class. If annual mileage is high, the running-cost gap against a class-average rival compounds quickly.
EPA puts annual fuel spend at about $4,000, $1,400 more than the $2,600 typical for the class. Over five years at 15,000 miles a year that is roughly $20,000, a $7,000 difference against a class-median vehicle.
Tailpipe CO₂ is 464 grams per mile — about 7 metric tons over 15,000 miles of driving.
