For a used Japanese luxury car in 2026, start with the Lexus IS, UX and GX, the Acura RDX and TLX, and the Infiniti QX50: CARFAX’s 2026 analysis found these 2019–2023 models had lower average unexpected-repair likelihood than its 9.0% luxury-car segment average. The shortlist below adds four category leaders from iSeeCars to cover more body styles and powertrains. It is a practical cross-section, not a definitive ranking: the sources measure different things, and no model-line statistic can guarantee the condition of a particular car.
How to read this used-car shortlist
CARFAX’s August 17, 2026 ranking estimates the likelihood of unexpected repairs over five years for 2019–2023 vehicles, using its maintenance-record analysis. Its reported 9.0% luxury-car segment average is a useful reference for the six models below with CARFAX estimates. A lower percentage is not a promise that an individual car will be trouble-free.
iSeeCars’ scores are not repair probabilities: they combine reliability, resale value and safety. Those scores should not be directly compared with CARFAX percentages. The candidates also differ in size, powertrain and intended use, so choose by fit and condition rather than treating the list as a precise order.
CARFAX also reports the share of each model line still on the road, but the start year differs by model. Those figures describe different spans and are not apples-to-apples durability rankings.

Six models with CARFAX repair-likelihood estimates
| Model | Type | CARFAX average unexpected-repair likelihood | CARFAX model-line share still on road | What to know |
|---|---|---|---|---|
| Acura RDX | Luxury SUV | 2.5% for 2019–2023 models; CARFAX, 2026 | 92.9% since 2007 | CARFAX says reliability improved by the end of the second generation in 2018 and the RDX has since been among its most reliable luxury SUVs. |
| Lexus IS | Luxury sedan | 2.8% for 2019–2023 models; CARFAX, 2026 | 69.4% since 2006 | CARFAX describes reliability as consistent. |
| Lexus UX | Small luxury SUV | 2.8% for 2019–2023 models; CARFAX, 2026 | 90.4% since 2019 | CARFAX notes a reliability dip in 2023 after the introduction of a new infotainment system. |
| Lexus GX | Luxury SUV | 3.0% for 2019–2023 models; CARFAX, 2026 | 87.8% since 2006 | CARFAX reports improvement in 2020 after a significant refresh, followed by a dip in 2023, the generation’s final year. |
| Acura TLX | Luxury sedan | 4.3% for 2019–2023 models; CARFAX, 2026 | 93.8% since 2015 | CARFAX describes above-average reliability throughout its run. |
| Infiniti QX50 | Luxury SUV | 4.7% for 2019–2023 models; CARFAX, 2026 | 94.1% since 2014 | CARFAX describes its repair statistics as consistently strong. |
The “still on the road” figures come from CARFAX, but their different starting years mean they should not be read as a direct comparison of survival over an equal ownership period.
Four more Japanese luxury options by category
iSeeCars’ comparison ranks these models within Japanese luxury categories and gives an overall quality score that incorporates reliability, resale value and safety. It does not provide the same model-year-specific repair-likelihood estimate CARFAX reports for the six vehicles above.
Rank #2
- Used Book in Good Condition
| Model | Category | iSeeCars quality score |
|---|---|---|
| Lexus RC 350 | Small/compact Japanese luxury car | 8.7/10; first in category |
| Lexus ES 350 | Midsize Japanese luxury car | 7.8/10; first in category |
| Lexus ES 300h | Japanese luxury hybrid | 7.9/10; first in category |
| Acura ILX | Small Japanese luxury car | 8.1/10 |
The Acura ILX is included as a compact-car alternative in the iSeeCars comparison; the captured comparison also lists Infiniti Q50 at 7.3/10. These category scores provide context, not a forecast for a specific model year or used example.
What the broader dependability data can—and cannot—tell you
JD Power’s 2026 U.S. Vehicle Dependability Study reports 204 problems per 100 vehicles overall and 217 per 100 in the premium segment. Lexus recorded 151 problems per 100 vehicles, the lowest figure among premium brands. Lower PP100 means fewer owner-reported problems. The study drew on responses from 33,268 original owners of 2023 model-year vehicles after three years of ownership.

- Used Book in Good Condition
That study is a useful reminder that newer luxury vehicles can still develop problems, but it is not a long-term used-car repair forecast and does not establish that every Lexus, Acura or Infiniti model is equally dependable. Its cohort, time horizon and measure differ from CARFAX’s repair-likelihood estimates and iSeeCars’ composite scores. JD Power director of auto benchmarking Jason Norton said in the 2026 release, “As owners hold onto their vehicles longer, the long-term ownership experience matters more than ever.”
Choose by vehicle needs, generation and ownership costs
Use the shortlist to narrow candidates, then compare examples in the same class and model-year range. A compact UX, midsize ES, sport sedan IS and larger GX solve different problems; an attractive reliability statistic does not make them interchangeable.
- Match space to use: Compare passenger room, cargo capacity and the type of driving you do before choosing between a sedan and SUV.
- Choose the powertrain deliberately: The ES 300h is the hybrid option on this list; compare its condition and service history with the conventional ES 350 rather than assuming their ownership profiles are identical.
- Pay attention to model-year changes: CARFAX specifically flags the 2023 UX infotainment update and the 2023 GX generation-end dip. Look closely at the exact year and equipment of any car you consider.
- Compare local asking prices: No current price comparison is established here. Check listings in your area and weigh price against mileage, maintenance documentation, condition and the specific year.
- Check safety by model year: A current-model safety award does not automatically apply to an older used example. IIHS’s 2026 Top Safety Picks include models such as the Lexus NX and Infiniti QX60, but that is current-year crashworthiness and crash-avoidance recognition—not a reliability rating or a rating for every earlier year.
Inspect the individual car before buying
A model’s average is only a starting point. Maintenance, prior damage, use and the specific vehicle’s present condition determine whether a particular used car is a sensible buy.
- Review the maintenance and ownership records. Look for evidence of routine service and investigate gaps or inconsistencies. A vehicle-history report can add context, but it cannot substitute for inspection.
- Check open recalls by VIN. Confirm the status for the exact vehicle rather than relying on a general model-year search.
- Arrange an independent pre-purchase inspection. Ask a qualified mechanic to assess mechanical condition and scan for diagnostic trouble codes. A scan is a screening aid: it cannot reveal every hidden defect or certify future reliability.
- Compare the inspection findings with the asking price. Use any needed repairs, missing records and condition concerns to decide whether to proceed, negotiate or walk away.
An optional OBD-II scanner can help a buyer read diagnostic codes, but it cannot establish reliability, expose every hidden issue or replace a qualified mechanic’s inspection.
