Infiniti recall campaign PC962 applies to certain 2023 QX55 vehicles with an incorrect passenger-side front door lock. The condition can prevent the right-front door from automatically locking; campaign eligibility is VIN-specific.

Common Symptoms

  • Right-front passenger door does not automatically lock
  • Open PC962 campaign for the VIN

How to Fix

Check the VIN through Infiniti or NHTSA. For an eligible vehicle, Infiniti campaign ITB23-013A directs the retailer to replace the passenger-side front door lock at no charge. The bulletin lists lock assembly 80500-9CM0A and three screws 80599-4AF0A for the campaign procedure.

Owners of the QX55 and platform-mate QX50 report the Forward Emergency Braking / Intelligent Emergency Braking system activating with no obstacle present, including hard braking while passing large trucks, coasting under bridges and overpasses, or on certain road surfaces. FEB can engage even with ProPILOT Assist off. Unexpected automatic braking in traffic is a rear-end-collision hazard. A related TSB notes the AEB warning light can blink in heavy rain/fog or when the windshield lane camera window is contaminated.

Common Symptoms

  • Automatic braking with no obstacle present
  • Hard braking under bridges/overpasses or passing trucks
  • AEB warning light blinking
  • Collision-warning chime for phantom objects
  • ProPILOT/adaptive cruise dropping out

How to Fix

Keep the front camera window (behind the windshield) and front radar/emblem area clean and free of film, mud, snow or aftermarket tint. Have the dealer scan the ADAS modules and apply any camera/radar calibration or software update per TSB. If phantom braking persists, request a diagnosis of the radar/camera alignment; the FEB sensitivity setting can be reviewed but the system should not be defeated permanently.

Nissan issued a large 2026 recall covering VC-Turbo four-cylinder vehicles including the Infiniti QX55, QX50 and Altima. Under certain operating conditions the engine can experience high oil temperatures that degrade lubrication of the crankshaft main bearing and the A-, C- and L-link bearings of the variable-compression mechanism. In the worst case a bearing seizes or a failed bearing breaches the engine block, causing catastrophic engine failure. This is a distinct defect from the previously documented oil-consumption issue. Nissan also announced a VC-Turbo warranty extension. Symptoms often precede failure and out-of-warranty engine replacements have run five figures.

Common Symptoms

  • Engine knocking or ticking noise
  • Metal shavings/debris in engine oil
  • Diesel-like pinging at idle
  • Sudden loss of power / stalling
  • Illuminated check-engine or malfunction light
  • Engine seizure

How to Fix

Have the VIN checked for the recall. The remedy reprograms the ECM, scans for diagnostic codes, and inspects the oil pan for metal debris; if metal is found the engine is replaced free of charge. Owners should keep to strict oil-change intervals, use the correct 0W-20 spec oil, and stop driving immediately if knocking, ticking or metal in the oil is noticed. Because a warranty extension applies, keep all service records to protect coverage.

Like the QX50, the QX55 with the VC-Turbo KR20DDET engine exhibits elevated oil consumption. The variable compression mechanism creates additional oil consumption pathways, and owners report needing top-offs between the 5,000-mile service intervals.

Common Symptoms

  • Low oil warnings between services
  • No visible external leaks
  • Oil level dropping 1+ quart per 3,000 miles

How to Fix

Monitor oil levels bi-weekly and top off with 0W-20 synthetic. Follow the Infiniti oil consumption test procedure if usage exceeds 1 quart per 3,000 miles. Warranty coverage may apply for excessive consumption.

The 2022 QX55 debut year drew numerous complaints of the 12V battery failing to hold a charge or discharging prematurely, leaving the vehicle with a no-crank/no-start condition, key-detection errors and a cascade of dashboard warning messages at startup. In one reported case a battery-related electrical failure led to a sudden loss of power steering assist, a serious safety concern. Parasitic draw from the vehicle's electronics and short-trip driving accelerate the problem.

Common Symptoms

  • No-crank / no-start, clicking on start
  • Multiple dashboard warning messages at startup
  • Key/fob not detected
  • Dim or flickering interior/dash lights
  • Battery repeatedly dead after sitting
  • Reported loss of power steering assist with electrical failure

How to Fix

Load-test the battery and charging system; replace with a correct OEM-spec Group 35/AGM battery if degraded. If the battery drains while parked, perform a parasitic-draw test to isolate a module (infotainment/telematics) staying awake. Reprogram/replace the battery and register it if the system requires. Address any charging (alternator) fault and keep the battery topped up on a maintainer during long storage.

The QX55 infotainment system experiences periodic freezing, slow boot times, and wireless Apple CarPlay disconnections. The system occasionally requires a manual reboot to restore functionality during driving.

Common Symptoms

  • Screen freezing during navigation
  • Wireless CarPlay disconnecting
  • Slow system boot after starting car

How to Fix

Update to the latest infotainment firmware. Perform a factory reset if issues persist. Delete and re-pair all Bluetooth devices. Infiniti has released multiple software updates addressing stability.

The QX55 pairs the torque-rich VC-Turbo engine with a Jatco Xtronic CVT. Owners and technicians report the classic Nissan/Infiniti CVT complaints: a rubber-band or 'revving' feel where engine RPM flares without corresponding acceleration, low-speed judder/shudder while slowing to a stop, hesitation and turbo lag off the line, and overheating under sustained load. CVTs are sensitive to the engine's low-end torque, and heat plus fluid breakdown accelerate internal wear. Judder trouble codes such as P17F0/P17F1 are associated with the family.

Common Symptoms

  • Engine RPM flares without acceleration (rubber-band feel)
  • Shudder/judder when slowing to a stop
  • Hesitation or turbo lag from a stop
  • Whining or droning noise
  • Harsh or delayed engagement
  • Overheating / limp mode under load

How to Fix

Start with a genuine Nissan NS-3 CVT fluid exchange and check for leaks or low fluid; heat is the primary enemy. A dealer scan for judder codes can call for a valve-body/pressure recalibration or valve-body replacement. Severe cases require a CVT rebuild or replacement. Frequent fluid checks and an auxiliary cooler help; avoid heavy towing.

Infiniti bulletin ITB22-025A applies to 2022 QX55 vehicles built on or before February 15, 2022. It covers a roaring noise caused by the engine cooling fan running on high without cycling when the air conditioning is also not cooling.

Common Symptoms

  • Roaring noise from the engine cooling fan assembly
  • Cooling fan runs on high without cycling
  • Air conditioning is not cooling

How to Fix

A qualified Infiniti technician should confirm both conditions and inspect the Denso part number on the cooling-fan assembly. ITB22-025A directs replacement of the engine cooling fan assembly when the installed part is outside the listed replacement set, and replacement plus configuration of the IPDM E/R when applicable.
