Searching for Infiniti QX70 repair in Phoenix? EZ Swap LLC is a Phoenix auto shop at 9050 N 9th St that repairs and maintains the Infiniti QX70 for model years 2014 to 2017. We diagnose the problem first, explain it in plain English, and quote the repair before we start.
Phoenix is demanding on a Infiniti QX70. Extreme heat, stop-and-go traffic and long highway miles on the I-17, the 51 and the Loop 101 all show up as wear. Below are the Infiniti QX70 problems owners report most often, what each one looks like from the driver's seat, and how we fix it.
Most Common Infiniti QX70 Problems in Phoenix
Ranked by owner complaints filed with the National Highway Traffic Safety Administration (NHTSA) for the QX70. Counts reflect reports filed, not the share of vehicles affected.
1. Air Bags
4 NHTSA owner complaints for the QX70 mention airbags and seat belts (17% of 23 reviewed).
What it looks like:
- Airbag or SRS warning light
- Seat belt that will not latch or retract
- Open safety recall notices
- Seat or restraint warning messages
What we do: Airbag and restraint issues are often tied to open safety recalls, which are repaired by the manufacturer at no cost to you. Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.
2. Electrical System
4 NHTSA owner complaints for the QX70 mention the electrical system (17% of 23 reviewed).
What it looks like:
- Slow cranking or clicking when starting
- Dim or flickering lights
- Battery or charging warning light
- Random electrical glitches and dead accessories
What we do: Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
3. Service Brakes

What it looks like:

- A soft or sinking brake pedal
- Steering wheel shake or pulling under braking

What we do: Brake complaints turn up on nearly every vehicle, and Phoenix stop-and-go traffic wears brake parts quickly. We measure pads and rotors, check calipers and fluid, and replace only what is worn. See our brake repair page.

Infiniti QX70 Maintenance in Phoenix Heat
- Test the QX70 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 QX70 brakes and tires twice a year; heat and stop-and-go driving wear both quickly
- Check coolant level and condition, and inspect belts and hoses for cracking
- Service the A/C early; a weak system rarely fixes itself
- Replace wiper blades and check lights, since sun destroys rubber and plastics
