On the 2022-2024 Infiniti QX55 2.0L VC-Turbo I4 (KR20DDET), 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.
On the 2022-2026 Infiniti QX55, 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.

On the 2022-2024 Infiniti QX55 2.0L VC-Turbo I4 (KR20DDET), 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.

On the 2022-2024 Infiniti QX55 2.0L VC-Turbo I4 (KR20DDET), 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.
On the 2022-2026 Infiniti QX55, 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.
