|---|---|---|---|---|
| UX 250h, UX 250h AWD | 7 / 10 | California LEV-III SULEV30 / Federal Tier 3 Bin 30 | All 50 states (federal, all altitudes); California and states following California standards | SmartWay |
| UX 200 | 6 / 10 | California LEV-III ULEV50 / Federal Tier 3 Bin 50 | All 50 states (federal, all altitudes); California and states following California standards | SmartWay |
Certified for all fifty states, so it can be registered new anywhere in the U.S.
The smog rating scores tailpipe pollutants other than greenhouse gases, 1 (worst) to 10 (best), and is comparable only within a model year. The standard is the federal bin or California tier the configuration was certified to. Both come from the EPA certificate behind the window sticker.

Filed by the manufacturer with NHTSA under the federal vehicle-identification rule and decoded from the VIN pattern — not a manufacturer press kit, so it describes the configurations we could identify rather than every trim (seen: 200 Base, 250h Base, 250h F Sport Premium, 250h Luxury). Figures for the trim you are looking at may differ.

Where a range is shown, those versions differ. Width is the body without mirrors, which is why it can read narrower than a brochure figure. Before we used it we checked it against the US manufacturer press kits we hold (27 Sep 2026): wheelbase agreed within 1% on every vehicle we could compare, length on 98%, and the curb weight fell inside the manufacturer's range on 96%.

NHTSA defect investigations
Electrical System:Propulsion System — Pedestrian alert sounds closed
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021. On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject mat

225/50/18 Tires have less that 2000 miles on them and they are pealing at the treads. Literally whole chunks are falling off the tires…looks like someone has been picking and pulling off pieces of my tires
I am filing an urgent safety complaint regarding a defective Bridgestone tire on my 2021 Lexus UX250h, purchased new in 2021. At 32,000 miles, the [front left] tire shows abnormal tread tearing and separation, while the other tires show normal wear.
The contact owns a 2021 Lexus UX250. The contact stated that while driving at 40 MPH, he T-boned another vehicle. The air bags failed to deploy. The air bag malfunction warning light was illuminated. The contact did not sustain any injuries. The vehicle was towed to a tow yard. A police report was filed.
Rear glass window is much to dark in standard oem built in tint into window. Can only see out clearly in broad day light otherwise much too dark. We have been involved in several near back up collisions even though we have a back up camera, we are used to looking back through the rear window and outside rear view mirrors.
The contact owned a 2021 Lexus UX 250 Hybrid. The contact stated that while their father was driving approximately at 65 mph when the warning for tire low pressure had illuminated. The driver pulled over to check the tires to the side of the road.
Tires came new with car in 2021. The two front tires are chunking. Back tires appear to be fine. Car is not out of alignment, has never been in an accident, no off roading or parking on gravel surfaces. Took it to a Lexus dealer and service rep. says he's never seen a car like this.
Complaint counts are raw owner reports to NHTSA, not verified defects, and scale with how many were sold. Use them to spot patterns, not to rank.
Reported by Lexus itself: 14 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 18 injured, as claimed, not verified — about 86 per 100,000 built.

A service bulletin is the manufacturer telling its dealers how to diagnose or repair a known condition. It is not a recall, not a finding that the vehicle is defective, and the work is not automatically free — though a bulletin is often what a dealer works from when you describe a symptom, so quoting the document number can save a diagnosis. The count is every communication filed; the list shows the most recent, one entry per campaign, because a single campaign is usually filed as several documents on the same day. The summaries are NHTSA's; the full documents come from the manufacturer.
Diagnostic trouble codes on file
Source: NHTSA manufacturer communications and complaintsCodes documented against this model year in the federal record. A code appearing here does not mean this vehicle will set it — it means the code is part of this nameplate-year's documented history.
| Code | What it means | Most often filed under | Where it appears |

| B15FE B15FE on Lexus → | Manufacturer-defined — the meaning is set by the automaker, not the standard. | Equipment | 2 bulletins |
Generic codes (the second character is 0 or 2) mean the same thing on every vehicle sold in the United States. Manufacturer-specific codes (1 or 3) mean whatever the automaker assigned, and no honest source can define them for you — which is why the ones here carry the evidence instead of a definition. A code is a link when enough separate federal documents name it across the catalogue to be worth a page of its own; the rest are listed here, where the vehicle is the context that makes them mean something.

At the New York inspection station
Source: New York State DMVIn New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Lexus UX failed the emissions check on 1.1% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 1.3% (every 2021 vehicle: 1.5%).

New York’s emissions test on these model years is an on-board diagnostics check: it fails a car whose check-engine light is on or whose self-tests have not finished. First inspections only, so a car that failed and came back is counted once; private and special plates, not taxis, livery or commercial plates. A rate appears only where at least 200 inspections stand behind it. “Every 2021 vehicle” is every 2021 model-year car, SUV and pickup inspected in the same window, all makes. This is the state’s record of test results, not a reliability score by itself. Source: New York State Department of Motor Vehicles, Vehicle Inspections (data.ny.gov, Open NY terms).

Source: EPA, NHTSA and manufacturer press kitsDoes the 2021 Lexus UX have any recalls?
No NHTSA recall campaigns are on file for the 2021 Lexus UX. New campaigns appear here within a week of NHTSA posting them, and a clean sheet on a recent model year often just means the vehicle is new.
How safe is the 2021 Lexus UX?
NHTSA gave the 2021 Lexus UX 5 stars overall in its New Car Assessment Program tests — 4-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it A (100/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2021 Lexus UX?
Across the 3 EPA-rated configurations of the 2021 Lexus UX, the best EPA combined figure is 42 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2021 Lexus UX?
Transport Canada measured it at 177.2 in long, 72.4 in wide (body, without mirrors), 60.6 in tall, on a 103.9 in wheelbase. Curb weight: 3,307–3,605 lb depending on configuration. Those are its measurements of the North American versions; every figure is in the table above.
What do owners complain about on the 2021 Lexus UX?
Owners have filed 8 complaints with NHTSA about the 2021 Lexus UX, most often about tires, unspecified, engine. Of those, 1 involved a crash, 1 a fire. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2021 Lexus UX?
The EPA smog rating for the 2021 Lexus UX runs 6 to 7 out of 10 across its configurations. That score covers tailpipe pollutants other than greenhouse gases, and it only compares vehicles within the same model year. It is certified for all fifty states, so it can be registered new anywhere in the U.S. Its configurations were certified to different standards — California LEV-III SULEV30, California LEV-III ULEV50, Federal Tier 3 Bin 30, Federal Tier 3 Bin 50 — which the table above lists per configuration.
Are there service bulletins for the 2021 Lexus UX?
The manufacturer has filed 212 service bulletins and related communications with NHTSA for the 2021 Lexus UX, most often covering equipment, electrical system, structure. The most recent is dated 2026-09-22. A bulletin is not a recall: it is the repair procedure a manufacturer sends its dealers for a condition it knows about, and the work is not automatically paid for. It is still worth knowing — if the symptom matches, quoting the bulletin number at the service desk can save a diagnosis. The document numbers and summaries are listed above.
How does the 2021 Lexus UX do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Lexus UX failed the emissions check on 1.1% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 1.3% (every 2021 vehicle: 1.5%). The figures are New York State DMV’s own inspection records, first inspections only, and the table above sets each one against every vehicle of the same model year.
Is the 2021 Lexus UX better than the 2021 Mazda CX-3?
The Lexus UX edges it, 97.1 to 91.7, on fuel & range. The Mazda CX-3 is ahead on safety and performance. We publish a full side-by-side of the 2021 Lexus UX against the 2021 Mazda CX-3 — specifications by family, equipment feature by feature, safety record and ownership costs. You can re-weight what matters to you and the verdict recalculates.

Sources & method
Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). The most serious recall counts in full and each further one counts 85% of the one before, because a vehicle sold in millions is recalled more often than a rare one without being more dangerous — and because a flat subtraction bottomed the scale out, scoring a vehicle with 22 recalls within a point of one with six. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Read it as what it counts: recall campaigns on the federal record, weighted by severity. The damping reduces the sales bias by roughly 40% but does not remove it: like our complaint counts, this is not normalized by how many were sold, so a best-seller still scores somewhat worse than an obscure model with the same real risk. NHTSA crash ratings, do-not-drive and park-outside advisories, and the crash, fire, injury and death counts in owner complaints are reported separately on every page and never blended into the letter — a vehicle can hold five stars and a poor letter at once, and where that happens we say so rather than leave you to notice. Because the scale subtracts from a clean sheet, a model year too new to have been recalled, complained about or bulletined scores full marks on an empty record; we label those grades provisional rather than present them as earned.
EPA figures come from fueleconomy.gov vehicle records. Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed nightly.
