Searching for Infiniti QX56 repair in Phoenix? EZ Swap LLC is a Phoenix auto shop at 9050 N 9th St that repairs and maintains the Infiniti QX56 for model years 2005 to 2010, 2012 to 2013. We diagnose the problem first, explain it in plain English, and quote the repair before we start.
Phoenix is demanding on a Infiniti QX56. 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 QX56 problems owners report most often, what each one looks like from the driver's seat, and how we fix it.
Most Common Infiniti QX56 Problems in Phoenix
Ranked by owner complaints filed with the National Highway Traffic Safety Administration (NHTSA) for the QX56. Counts reflect reports filed, not the share of vehicles affected.
1. Service Brakes
104 NHTSA owner complaints for the QX56 mention brakes (29% of 358 reviewed).
What it looks like:
- Squealing, grinding or scraping when you stop
- A soft or sinking brake pedal
- Steering wheel shake or pulling under braking
- Brake warning light
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.
2. Engine
55 NHTSA owner complaints for the QX56 mention the engine and cooling system (15% of 358 reviewed).
What it looks like:
- Check engine light or rough idle
- Overheating or coolant smell
- Loss of power or poor mileage
- Oil leaks or low oil
What we do: Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition. See our check engine light diagnostics and oil change & maintenance pages.
3. Electrical System
46 NHTSA owner complaints for the QX56 mention the electrical system (12% of 358 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.
4. Suspension
31 NHTSA owner complaints for the QX56 mention the suspension (8% of 358 reviewed).
What it looks like:
- Clunks and knocks over bumps
- Bouncy or nose-diving ride
- Uneven tire wear
- Car pulls to one side
What we do: Suspension wear shows up as clunks, pulling and uneven tires. We inspect shocks, struts, bushings and joints and align the car after repairs. See our suspension & alignment page.
5. Fuel/Propulsion System
29 NHTSA owner complaints for the QX56 mention the fuel system (8% of 358 reviewed).
What it looks like:
- Hard starting or stalling
- Engine cranks but will not start
- Hesitation or surging
- Fuel smell
What we do: Fuel system problems can cause stalling, hard starts and poor mileage. We test fuel delivery and related sensors to find the real cause. See our no-start diagnostics and check engine light diagnostics pages.
Infiniti QX56 Check Engine Codes to Know
When a QX56 owner mentions a trouble code in a complaint to NHTSA, these come up most: C1179 (manufacturer-specific chassis code), P0011 (intake camshaft timing over-advanced (bank 1)), P0300 (random or multiple cylinder misfire). We scan and test before replacing parts. See the full QX56 code list and our check engine light diagnostics.
Infiniti QX56 Maintenance in Phoenix Heat
- Test the QX56 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 QX56 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
