Independent model research guide
Build the INFINITI QX55 repair record before drawing conclusions.
Use this page as a document-building path for the exact vehicle—not as a substitute for its warranty, VIN record, final repair orders, or legal advice based on the facts.
Badges and model names do not always identify the complete drivetrain or warranty package. Confirm the build data and coverage before comparing another vehicle’s history.
Model-aware documentation
Issue categories to document for a INFINITI QX55.
These are investigation prompts, not statements that the model has each problem. Select only the categories that match the actual vehicle and repair orders.
Climate control and thermal performance
Track weak cooling or heating, odors, intermittent operation, ambient conditions, and parts or refrigerant work performed.
Water intrusion, seals, noise, or vibration
Photograph the location and resulting damage, note weather conditions, and preserve any leak testing or body-repair findings.
Engine, power delivery, or stalling
Record the operating conditions, warning messages, speed, temperature, and whether the concern returned after repair.
Transmission, shifting, or drivability
Note hesitation, harsh engagement, slipping, vibration, or loss of response and the exact conditions in which it occurs.
Electrical power and recurring warnings
Save photographs of warning lights, no-start events, battery replacements, diagnostic codes, and modules tested or replaced.

Infiniti QX55: NHTSA records by model year
Find your model year, distinguish a safety recall from a service bulletin or owner report, and compare the records with your vehicle’s VIN, equipment, and repair history.

Model year 2022
2022 Infiniti QX55
The 2022 QX55 index includes 1 distinct safety campaign, covering engine and cooling. Owner-report entries are most numerous in engine and cooling (5) and airbags, belts, and seating (1). 72 manufacturer communications are organized separately below so workshop instructions are not mistaken for confirmed owner failures. Start with any applicable safety instructions, then match the service documents and reported conditions to the actual repair orders.

Complete loss of motive power due to engine failure
The 2022 QX55 is listed in this investigation record. An investigation concerns an agency inquiry; its opening is not a final defect determination, and closure alone is not a finding that every vehicle is safe or repaired.
Agency summary excerpt: “On December 13, 2023, the Office of Defects Investigation (ODI) opened PE23-023 to investigate allegations of engine failures leading to loss of motive power in model year (MY) 2021-2023 Nissan Rogue; MY 2019-2021 Nissan Altima; and MY 2019-2021 Infiniti QX50 …”
Agency disposition and source
In addition, Nissan will extend the vehicle warranty to 10 years and 120,000 miles for the recall subject vehicle population after the dealer performs the inspection. In view of the recall action (25V437) taken by Nissan, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.

NHTSA investigation activity
Agency record · Closed
Complete loss of motive power due to engine failure
The 2024 QX55 is listed in this investigation record. An investigation concerns an agency inquiry; its opening is not a final defect determination, and closure alone is not a finding that every vehicle is safe or repaired.
Agency summary excerpt: “On December 13, 2023, the Office of Defects Investigation (ODI) opened PE23-023 to investigate allegations of engine failures leading to loss of motive power in model year (MY) 2021-2023 Nissan Rogue; MY 2019-2021 Nissan Altima; and MY 2019-2021 Infiniti QX50 …”
Agency disposition and source
In addition, Nissan will extend the vehicle warranty to 10 years and 120,000 miles for the recall subject vehicle population after the dealer performs the inspection. In view of the recall action (25V437) taken by Nissan, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.

No safety-recall campaign was supplied for this model year in the indexed search. That is not a current VIN clearance. 2 manufacturer communications are organized separately below so workshop instructions are not mistaken for confirmed owner failures. Start with any applicable safety instructions, then match the service documents and reported conditions to the actual repair orders.

Repair chronology
Turn every QX55 visit into a usable timeline.
Place the final repair orders in date and mileage order. Compare the customer complaint, technician findings, correction, and post-repair result instead of relying only on a dealer summary or online discussion.
Do not combine multiple visits into one estimate. Open and close dates, mileage, parts delays, diagnostic time, and the date the vehicle was actually available can answer different questions.

2Complaint in the driver’s words
3Diagnosis and testing performed
4Parts, software, or correction
5Days unavailable and post-repair result
California legal framework
The statute applies to the evidence—not the badge.
California Civil Code section 1793.2 addresses warranty repair obligations and, in specified circumstances, replacement or restitution after a reasonable number of repair attempts. Section 1793.22 defines the Tanner presumption and “nonconformity.” Those provisions require a fact-specific analysis.
Applicable warranty
Identify the written coverage in effect when the concern was presented.
Repair opportunity
Show when and how the manufacturer or authorized facility received the vehicle.
Substantial impairment
Document the effect on use, value, or safety rather than relying on labels.
Remedy analysis
Compare restitution, replacement, negotiated resolutions, offsets, and supporting damages.
Warranty and escalation record
Separate the INFINITI QX55 warranty from other contracts.
A manufacturer warranty, certified coverage, dealer promise, and separately purchased service contract may have different obligors and terms. Preserve each document instead of calling all coverage an “extended warranty.”
Save every INFINITI dealer message, repair authorization, parts-delay explanation, manufacturer case number, and written response. A phone call may matter, but a dated email, text, or letter usually makes the sequence easier to prove.
Primary and practical sources
Verify the law, vehicle, and warranty separately.

Clear answers
INFINITI QX55 lemon law questions
Can a INFINITI QX55 qualify under California lemon law?
It may, but the model name alone does not decide eligibility. A review should match the exact vehicle to an applicable written warranty and examine the repair opportunities, recurring nonconformity, mileage, downtime, and effect on use, value, or safety.
How many QX55 repair attempts are required?
There is no universal count that decides every case. California’s Tanner presumption describes specific circumstances, but claims can require a broader analysis of whether the manufacturer had a reasonable opportunity to repair the warranty problem.
Does a recall or service campaign prove that my QX55 is a lemon?
No. Recall, campaign, complaint, or bulletin information may provide context, but it does not prove the condition exists in this vehicle or establish a lemon law claim. Use VIN-specific information and the actual repair record.
What INFINITI QX55 records should I save?
Keep the purchase or lease agreement, warranty booklet, every final repair order, current registration and payoff information, photographs or videos, towing and rental records, and dealer or manufacturer messages and case numbers.
Can a used or leased QX55 qualify?
Possibly. The answer depends on the transaction, vehicle history, warranty that applied, timing of the repair visits, and other facts. A used or leased vehicle should be evaluated from its own documents.
What remedies may be available for a qualifying INFINITI QX55?
Depending on the facts and current law, possible outcomes can include restitution or repurchase, replacement, a negotiated cash resolution, warranty relief, incidental damages, or other remedies. No particular outcome is guaranteed.
