2022 INFINITI
QX55SUV
SUV
The 2022 INFINITI QX55 is a sport-focused luxury crossover coupe — essentially a fastback-roofed version of the QX50 — targeting buyers who want style and premium driving feel over maximum cargo room. It's powered by Infiniti's VC-Turbo 2.0L variable-compression four-cylinder paired with a CVT and standard AWD. That powertrain is genuinely clever engineering, continuously varying its compression ratio to balance power and efficiency. The QX55 sits in a small but growing segment of coupe-SUVs. Interior quality and ride comfort are genuine strong suits, with available Bose audio, quilted leather, and a driver-focused cockpit. The trade-off is reduced rear headroom and cargo space compared to its QX50 sibling — the sloping roofline costs you practicality. For Lake Geneva-area drivers, the standard AWD is a real asset on snowy back roads. Just be aware the vehicle requires premium fuel, and CVT service intervals need to be taken seriously on a drivetrain that was already generating mixed long-term reviews across Infiniti's lineup.

Maintenance schedule
- 1 Every 5,000 miles or 6 months, whichever comes first Engine Oil & Filter Change
The VC-Turbo's variable-compression mechanism and turbocharger depend on clean, full-pressure oil. The 0W-20 full synthetic spec is mandatory — don't substitute conventional oil. Use 5.1 qts including filter. This is the single most important service on this vehicle.
- 2 Every 60,000 miles under normal use; every 30,000 miles if you tow or drive aggressively CVT Fluid Change (NS-3)
Infiniti's CVTs are the most failure-prone component in the lineup. Fresh NS-3 fluid is cheap insurance. Only use Infiniti/Nissan NS-3 — off-brand CVT fluids are not compatible and can cause immediate damage.
- 3 Every 7,500 miles Tire Rotation
AWD and performance tire sizing accelerate uneven wear. Consistent rotation extends tire life significantly and keeps AWD wear balanced across all four corners.
- 4 Every spring and fall Sunroof Drain Tube Flush
Especially important in Lake Geneva where leaves, road grit, and freeze-thaw cycles clog drain tubes quickly. A simple flush with compressed air or water takes minutes and prevents hundreds of dollars in interior water damage.
- 5 Every 30,000 miles or 36 months Air Filter Replacement
The turbo pulls a high volume of air; a clogged filter forces the engine to work harder and can affect boost response. Wisconsin gravel and unpaved road driving may shorten this interval — inspect annually.
- 6 Every 15,000 miles or 12 months Cabin Air Filter Replacement
Protects HVAC system and keeps defroster airflow strong — critical for Wisconsin winters. Road salt dust and pollen load these up faster than the schedule suggests; inspect yearly.
- 7 Every 2 years regardless of mileage Brake Fluid Flush (DOT 3)
Brake fluid absorbs moisture over time, lowering its boiling point. In Wisconsin, where brakes work hard on wet/icy roads and during high-speed stops, fresh fluid is a safety item, not optional.
- 8 Every 5 years or 105,000 miles; inspect annually for freeze protection Coolant System Inspection & Flush
Infiniti's blue long-life coolant should be tested for freeze protection every fall before Lake Geneva winters hit. Sub-zero temperatures demand the cooling system be in spec — don't assume it is just because it's new-ish.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$800 – $1,400
Fuel
Premium unleaded required. At current Midwest averages (~$3.80–$4.20/gal for premium) and 25 combined MPG, expect $2,100–$2,600/year at 15,000 miles annually.
Insurance
Expect $1,400–$2,000/year in the Lake Geneva area for a luxury crossover in this price range, depending on driving record and coverage level.
Annual maintenance on an independent-shop basis runs $800–$1,400 in the early years, covering oil changes, rotations, filters, and periodic CVT fluid. That number climbs if the CVT needs fluid service, tires need replacement, or infotainment software work arises outside warranty. Premium fuel is a fixed ongoing cost — budget ~$200+ more per year versus a regular-gas vehicle. Overall cost of ownership is moderate-to-high for the luxury crossover segment, but not exceptional. The biggest financial risk is CVT neglect; stay on the fluid schedule and that risk drops substantially.
Seasonal care
Lake Geneva, WI Winter
- Test battery load every October — cold cranking amps drop sharply in sub-zero temps, and the VC-Turbo's start-stop cycles stress the battery more than a conventional engine. Replace proactively if the battery is over 4 years old.
- Switch to dedicated winter tires if you're on performance summer rubber — all-season tires are the minimum; summers become dangerous below 40°F. The AWD helps traction, but it doesn't help you stop.
- Flush sunroof drains before freeze-up. Water trapped in a blocked drain tube freezes, backs up, and enters the headliner. A five-minute fall flush saves a $400+ interior repair.
- Verify coolant freeze protection to at least -34°F before the first hard freeze. Infiniti blue long-life coolant can be tested with an inexpensive refractometer.
- Use a winter-grade washer fluid rated to -20°F or lower. The QX55's large windshield and raked glass catch a lot of road spray — standard fluid will freeze on contact at Wisconsin temperatures.
- Keep the fuel tank above half when temperatures drop below 0°F to reduce condensation in the fuel system and ensure adequate fuel pump cooling.
Summer
- Check tire pressure every month — heat causes pressure to rise ~1 PSI per 10°F. Over-inflated tires on performance fitment wear the center tread faster and reduce wet grip.
- Run the A/C on MAX cool for a few minutes after starting on hot days to purge heat-soaked air from the cabin before engaging normal recirculation — the QX55's panoramic roof glass increases heat buildup significantly.
- Inspect the A/C system for refrigerant leaks each spring. If cabin cooling seems reduced, address it before summer peaks — recharging is straightforward but finding a leak early is cheaper than compressor damage.
- Check brake pad thickness heading into summer. Aggressive driving on warm roads increases brake fade risk if pads are marginal.
- Clean the undercarriage and wheel wells in April/May to remove accumulated road salt before it continues to corrode brake lines, suspension hardware, and exhaust components through the warm months.
