Source: NHTSA complaints and recalls databases, read on October 12, 2026. Complaints are reports filed by owners and are not verified by NHTSA. Counts are not adjusted for how many of each model were sold, so best-selling models appear higher.

The QX60 leads with 586 complaints, most of them about powertrain and engine. That does not make it the worst Infiniti. A model that sells in large numbers collects more reports, and these counts are not adjusted for sales.

Use the table to know where to look. If you own or are buying one of these models, ask about the area in the third column first, and price the repair with the repair cost estimator.

02Problem areas

Where Infiniti Problems Concentrate

Recent model years have had less time to gather complaints, so a short bar at the bottom is not yet good news.

A year with many complaints is one to inspect closely, not one to rule out. The fault may have been fixed under recall, and a well-maintained car from a busy year can be a better buy than a neglected one from a quiet year.

Before you buy any used Infiniti, decode the VIN, check it for open recalls and follow the inspection checklist. A complaint count cannot tell you about the one car in front of you.

Check your VIN at NHTSA

A recall is free to have repaired at an Infiniti dealer. The lookup shows only the recalls still open on your vehicle.

05Maintenance schedule

Infiniti Maintenance Schedule

Typical service intervals for a gasoline Infiniti. Your owner’s manual has the exact figures for your engine.

Build a schedule for your mileage

Typical maintenance intervals for an Infiniti
Service	Typical interval	Good to know
Engine oil and filter	5,000 to 10,000 miles	Full synthetic sits at the long end. Short trips and towing shorten it.
Tire rotation	5,000 to 8,000 miles	Easiest to do at every oil change.
Cabin air filter	15,000 to 30,000 miles	Sooner in dusty or high-pollen areas.
Engine air filter	15,000 to 30,000 miles	Inspect at every oil change and replace when dirty.
Brake fluid	Every 2 years or 30,000 miles	It absorbs moisture with age, whatever the mileage.
Transmission fluid	30,000 to 60,000 miles	Varies widely, and some manuals allow longer. Use only the specified fluid.
Engine coolant	30,000 to 60,000 miles	Long-life coolants can go further. Never mix types.
Drive belt inspection	60,000 to 100,000 miles	Replace at the first cracks, fraying or squeal.
Timing belt, if fitted	60,000 to 100,000 miles	Engines with a timing chain do not have this service.
Spark plugs	30,000 to 100,000 miles	Copper plugs wear fastest. Iridium and platinum last longest.

Typical intervals drawn from AAA's maintenance guidance, not Infiniti's own schedule. Follow the schedule in your owner's manual, and use its severe-service intervals if you tow, make short trips or drive in extreme heat or cold.

06Manufacturer OBD2 codes

Infiniti OBD2 Codes

How to read the codes an Infiniti stores, and why some of them mean something different on another make.

A Infiniti stores two kinds of trouble code. Generic codes, which have 0 as their second character, mean the same thing on every make: P0420 is a catalyst efficiency fault on a Infiniti exactly as it is on any other car. Manufacturer-specific codes, which have 1 as their second character, are defined by Infiniti and can mean something different elsewhere.

We do not publish a list of Infiniti’s own P1 codes, because we could not verify one against Infiniti’s service information. For a P1 code, use a scanner that reads Infiniti codes, or ask an Infiniti dealer to look it up.

08Questions

Infiniti: common questions.

What are the most common Infiniti problems?

Among 2010 to 2026 model-year Infiniti vehicles, the areas owners report most often to NHTSA are engine (20% of complaints), powertrain (19% of complaints) and airbags (18% of complaints). A complaint is an owner's report, not a confirmed defect.

Which Infiniti model has the most complaints?

The QX60, with 586 complaints on file for 2010 to 2026 model years. Its 2014 model year has the most, at 199. Popular models attract more complaints simply because more of them are on the road.

How do I check an Infiniti for recalls?

Enter the 17-character VIN in NHTSA's recall lookup at nhtsa.gov/recalls. It shows safety recalls that have not been repaired on that exact vehicle, and recall repairs are carried out by the manufacturer's dealers at no charge.

How often does an Infiniti need servicing?

Most gasoline cars need an oil change and tire rotation every 5,000 to 10,000 miles, filters every 15,000 to 30,000 miles and brake fluid every two years. Your Infiniti owner's manual gives the exact schedule for your engine.
