NHTSA 5-Star Safety Rating
Complaints for the 2015 Infiniti Q70 are thin in number but cluster most around the powertrain. Owners most frequently describe the transmission getting stuck in a low gear, typically first or second, accompanied by a check engine light, with the problem appearing at varying mileages during highway driving. A couple of owners report vehicle speed control failures, with one describing a situation where the accelerator became unresponsive during cruise control use after an "Intelligent Key Not Detected" warning appeared, requiring the car to be coasted off the highway. Engine-related reports include stalling during low-speed maneuvers, such as a left turn, with the vehicle restarting but only limping home at very low speed. One isolated report mentions a steering wheel that continued rotating without resistance during a parking maneuver, though a dealer was unable to reproduce it.
