| Avalon | 3 / 10 | Federal Tier 3 Bin 125 / California LEV-II ULEV | All 50 states (federal, all altitudes); California and states following California standards | — |
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.

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

Air Bags: Air Bag/Restraint Control Module — Electrical overstress closed
The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW. The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with ma

Whether any of this applies to one specific Avalon
A campaign covers a build range, not a model year, so two identical-looking cars from 2018 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Toyota publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.
Hear about a recall before the letter does
The manufacturer’s letter is the last step of a recall: it has up to 60 days after filing to mail owners, at the address on the registration. We email you the day NHTSA posts a recall on the 2018 Toyota Avalon, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

In owners' own words
Filed with NHTSA by the people who own these cars, one per problem area. Quoted as written, with anything identifying removed.
The contact owns a 2018 Toyota Avalon Hybrid. The contact stated that the navigation system, the radio, and the upper third brake light was not functioning properly. The contact took the vehicle to the local dealer, where it was diagnosed with needing the EMU in the computer on the air bag that was malfunctioning to be replaced.
Involved in a 2 vehicle accident on October 26th. My car is totaled and so is the other car. No airbags deployed and my drivers side seat belt failed to lock in the accident. I was injured and taken by ambulance to hospital
Date of safety issue: July 12, 2023 Location: Piper Glen Shopping Center, Rea Road, Charlotte NC (destination was Run For Your Life at 6416 Rea Road - within the shopping center). Time: Approximately sometime between 1:30 and 2:00 ET Police Report Complaint # - On July 12, 2023 I entered a parking lot at a busy retail establishment.
Hello, My name is . I bought my car from Longo Toyota in El Monte about 15 months ago. The car was certified preowned and had a Carfax report with no accident reported history. That is exactly why I bought the car, because this was going to be my family car.
Intermittently, unpredictably, for several seconds at a time, the engine almost quits, especially when accelerating So far, it has not happened in heavy traffic, but if it did, it would create a possibly major safety hazard. I have not taken it to a dealer yet.
At approximately 42000 miles with no significant issues and no front end damages, the steering failed as I was driving at highway speed (70 mph) on a 2 lane road approaching a 90 degree curve.
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 Toyota itself: 17 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 25 injured, as claimed, not verified — about 62 per 100,000 built.

When owners reported it
miles, typically
Half the 14 owner reports with an odometer reading on file fall between 4,000 and 35,000 miles. That is when problems get reported, which is not the same as when they start — and not a failure rate, because nobody knows how many of these cars never had a problem at all.
Odometer readings as filed by owners with NHTSA. Readings under 100 or over 400,000 miles are dropped as data entry rather than history, and a component needs at least 12 readings before a median is shown for it.

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

| P0A7F P0A7F on Toyota → | Manufacturer-defined — the meaning is set by the automaker, not the standard. | Engine | 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.

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 2018 vehicle” is every 2018 model-year car, SUV and pickup inspected in the same window, all makes.

Avalon by model year
all years, side by side →Common questions about the 2018 Avalon
Source: EPA, NHTSA and manufacturer press kitsDoes the 2018 Toyota Avalon have any recalls?
NHTSA has posted 2 recall campaigns for the 2018 Toyota Avalon. The most serious on file is 20V024000, covering Air Bags. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2018 Toyota Avalon?
NHTSA gave the 2018 Toyota Avalon 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 B (85/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2018 Toyota Avalon?
Across the 2 EPA-rated configurations of the 2018 Toyota Avalon, the best EPA combined figure is 40 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2018 Toyota Avalon?
Transport Canada measured it at 195.3 in long, 72.4 in wide (body, without mirrors), 57.5 in tall, on a 111.0 in wheelbase. Curb weight: 3,549 lb. Those are its measurements of the North American versions; every figure is in the table above.
What do owners complain about on the 2018 Toyota Avalon?
Owners have filed 25 complaints with NHTSA about the 2018 Toyota Avalon, most often about air bags, unspecified, steering. Of those, 7 involved a crash, 4 reported injuries. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2018 Toyota Avalon?
The EPA smog rating for the 2018 Toyota Avalon runs 3 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-II ULEV, California LEV-III SULEV30, Federal Tier 3 Bin 125, Federal Tier 3 Bin 30 — which the table above lists per configuration.
Are there service bulletins for the 2018 Toyota Avalon?
The manufacturer has filed 259 service bulletins and related communications with NHTSA for the 2018 Toyota Avalon, most often covering equipment, structure, electrical system. The most recent is dated 2026-02-13. 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 2018 Toyota Avalon do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2018 Toyota Avalon failed the emissions check on 0.90% of first inspections — lower than the 3.0% for every 2018 model-year vehicle inspected; and the safety inspection on 0.90% (every 2018 vehicle: 1.9%). 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.

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.
