2013 Infiniti
JX35
3.5L V6
The 2013 Infiniti JX35 was Infiniti's first entry into the three-row luxury crossover segment, built on the Nissan Pathfinder/Murano platform at a U.S. plant in Smyrna, Tennessee. It seats up to seven and pairs a smooth 3.5L V6 with a CVT, aiming at buyers who want near-luxury refinement without the bulk of a full-size SUV. Infiniti renamed it the QX60 for 2014, so the JX35 was a one-year-only nameplate — though mechanically it's essentially the same vehicle. The JX35 hits a sweet spot for family hauling: quiet cabin, generous third-row access via a sliding second row, and a long feature list for the money at its original price point. Fuel economy is middling for the class at 20 mpg combined, and the CVT can feel sluggish under hard acceleration. It's a comfort-first crossover, not a sporty one. Buyers should understand this is a relatively front-wheel-drive-biased platform — the standard FWD configuration is the most common. AWD was a popular option. The VQ35DE engine is a proven, high-mileage unit, but the CVT and VVEL variable valve system demand strict oil-change discipline to avoid expensive repairs.

Known for
- Smooth, quiet V6 powered by the dependable VQ35DE engine
- Practical three-row layout with sliding second-row seats
- Upscale interior finish at a price below European rivals
- One-year-only JX35 nameplate (mechanically identical to 2014+ QX60)
- Front-wheel-drive bias with available AWD
Best for
- Families needing a third row without a full-size SUV
- Highway commuters who prioritize cabin quiet over fuel economy
- Buyers wanting near-luxury features at a used-market value price
- Drivers comfortable with FWD in light winter conditions
Watch for
- CVT longevity — failure is expensive and heavily tied to oil-change history
- VVEL camshaft and VTC actuator issues if oil changes were skipped
- AWD transfer case and rear differential fluid often neglected on used examples
- Infotainment and touchscreen quirks on aging InTouch systems
- Timing chain stretch at higher mileages if oil was not changed frequently

Maintenance schedule
- 1 Every 5,000 miles or 6 months — do not stretch to the 7,500-mile display interval Engine Oil Change
The VQ35DE's VTC actuators and oil passages clog with sludge quickly if oil is not changed frequently. This is the single most important maintenance item on this vehicle. Use the manufacturer-specified viscosity (5W-30 or 0W-20 depending on build spec).
- 2 Every 60,000 miles CVT Fluid Flush
Nissan officially calls CVT fluid 'lifetime,' but this is widely regarded as optimistic. Independent shops and CVT rebuild specialists strongly recommend flushing at 60k mi. Skipping this is the leading cause of premature CVT failure on this platform.
- 3 At 80,000 miles or at first sign of cold-start rattle Timing Chain and VTC Actuator Inspection
Timing chain stretch and VTC actuator wear are oil-maintenance-dependent. If you hear a rattle on cold start that disappears after 60 seconds, have it diagnosed before it becomes a full chain job.
- 4 Every 105,000 miles Spark Plugs (Iridium)
Factory iridium plugs have a long service life, but worn plugs stress the ignition coils. Replacing plugs on schedule avoids coil failure, which is a separate and added expense.
- 5 Every 2 years regardless of mileage Brake Fluid Flush
Brake fluid absorbs moisture over time, lowering its boiling point and corroding ABS components. Wisconsin road salt accelerates corrosion in brake line fittings.
- 6 Every 30,000 miles AWD Transfer Case and Rear Differential Fluid (AWD models)
These are commonly skipped on used crossovers. Old fluid causes premature wear in the rear diff and transfer case. Check service history on any used purchase — this is often never done.
- 7 Every 15,000–20,000 miles or annually Cabin Air Filter
Wisconsin's mix of pollen, road dust, and winter salt debris clogs cabin filters quickly. A restricted filter stresses the HVAC blower motor.
- 8 Every 5 years / 100,000 miles Coolant System Inspection and Flush
The VQ35DE runs warm and degraded coolant accelerates corrosion in aluminum cylinder heads. Flush and refill with Nissan-approved long-life coolant on schedule.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$900 – $1,800
Fuel
At 20 mpg combined and ~15,000 miles/year, expect roughly $1,800–$2,200/year at current Midwest regular unleaded prices. This engine requires regular unleaded (87 octane).
Insurance
Expect $1,200–$1,800/year for a typical driver in the Lake Geneva area. Luxury brand designation adds slightly to comprehensive rates versus a comparable Toyota or Honda.
Routine annual maintenance (oil changes, filters, brakes) runs $900–$1,800 at an independent shop. If the CVT or timing components have been neglected, a single repair event can add $1,500–$6,500 in one visit. Budget for CVT fluid service and oil changes religiously — this vehicle rewards preventive spending and punishes deferred maintenance hard.
Seasonal care
Lake Geneva, WI Winter
- Switch to a full-synthetic 0W-30 or 5W-30 oil before temperatures drop below 0°F — cold-start oil flow directly protects the VTC actuators and timing chain from rattle damage.
- Test the battery every October. The VQ35DE is a large-displacement engine and requires strong cold-cranking amps — a weak battery strains the charging system and leads to no-starts in sub-zero temps.
- Use winter-rated windshield washer fluid rated to at least -20°F. The standard reservoir holds over a gallon; refill before the season.
- Inspect and replace wiper blades with winter-specific blades before first snowfall. The tall windshield means larger blades with more surface area to freeze.
- Flush and top off coolant to the correct 50/50 mix — verify freeze protection to at least -34°F for Wisconsin winters.
- Rinse the undercarriage at a self-serve car wash every 2 weeks during heavy salting seasons. Road salt pools in the subframe and rear suspension mounting points on this platform.
Summer
- Check tire pressure monthly — tires gain approximately 1 PSI for every 10°F increase in ambient temperature, leading to overinflation on hot pavement.
- Inspect the A/C system for refrigerant level and condenser debris before Memorial Day. The JX35's wide front end collects bugs and road debris in the condenser fins, reducing cooling efficiency.
- Check engine coolant level and condition. Heat soak after stop-and-go driving stresses the cooling system — inspect the radiator cap and hoses if the vehicle has over 80k miles.
- Park in shade when possible. The large panoramic roof option (if equipped) significantly increases interior heat buildup, which accelerates dashboard and trim degradation over time.
