Infiniti Q70 Maintenance in Phoenix Heat
- Test the Q70 battery before every summer, and replace it proactively around the 3-year mark
- Follow the severe-service schedule for oil and fluids, since Phoenix heat and traffic count as severe use
- Inspect Q70 brakes and tires twice a year; heat and stop-and-go driving wear both quickly
