NHTSA defect investigations

Engine — Engine failure open

The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline.  The subject engine failures were analyzed as part of a Recall Query (RQ24013).  It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751.  Based on analysis of data from RQ24013,

Engine And Engine Cooling:Engine — No Restart After Auto Start/Stop Engages open

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020

Engine — Engine failure closed

On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of

Whether any of this applies to one specific TLX

A campaign covers a build range, not a model year, so two identical-looking cars from 2020 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Acura 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 2020 Acura TLX, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

Reported by Acura itself: 19 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 21 injured, as claimed, not verified — about 66 per 100,000 built.

When owners reported it

Reported at 62k

miles, typically

Half the 14 owner reports with an odometer reading on file fall between 45,000 and 90,000 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.

Too few readings for a curve — the 14 on file: 1 under 10k, 1 20k–30k, 3 40k–50k, 2 60k–70k, 3 70k–80k, 2 90k–100k, 2 100k–150k.

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 report under the General Order is a notice the manufacturer or operator must file within days of hearing of a crash in which a Level 2 driver-assist or automated-driving system was engaged within 30 seconds of impact. It is filed before anything is verified, and entities with telematics hear of far more crashes than entities that rely on complaints, so counts say as much about the reporting as about the car and are not comparable across makes.

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.

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 2020 vehicle” is every 2020 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).

Common questions about the 2020 TLX

Source: EPA, NHTSA and manufacturer press kits

Does the 2020 Acura TLX have any recalls?

NHTSA has posted 5 recall campaigns for the 2020 Acura TLX. The most serious on file is 26V332000, covering Air Bags. 1 campaign is phased, so the repair reached some model years before others. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2020 Acura TLX?

NHTSA gave the 2020 Acura TLX 5 stars overall in its New Car Assessment Program tests — 5-star frontal crash, 5-star side crash, 5-star rollover. WhichTrim also grades it C (70/100) on its recall record, which is a different question from crash protection.

What is the fuel economy of the 2020 Acura TLX?

Across the 6 EPA-rated configurations of the 2020 Acura TLX, the best EPA combined figure is 27 mpg. Figures are the EPA's own, per configuration, and every one is listed above.

What are the dimensions of the 2020 Acura TLX?

Transport Canada measured it at 190.6 in long, 72.8 in wide (body, without mirrors), 57.1 in tall, on a 109.4 in wheelbase. Curb weight: 3,565–3,818 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 2020 Acura TLX?

Owners have filed 63 complaints with NHTSA about the 2020 Acura TLX, most often about engine, fuel/propulsion system, electrical system. Of those, 4 involved a crash, 1 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 2020 Acura TLX?

The EPA smog rating for the 2020 Acura TLX is 3 out of 10. 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 ULEV125, Federal Tier 3 Bin 125 — which the table above lists per configuration.

Are there service bulletins for the 2020 Acura TLX?

The manufacturer has filed 50 service bulletins and related communications with NHTSA for the 2020 Acura TLX, most often covering engine, fuel/propulsion system, electrical system. The most recent is dated 2026-09-25. 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 2020 Acura TLX do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2020 Acura TLX failed the emissions check on 9.2% of first inspections — higher than the 2.2% for every 2020 model-year vehicle inspected; and the safety inspection on 1.2% (every 2020 vehicle: 1.6%). 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.

What we hold, and what an empty row means

Paid vehicle-history reports will not tell you the difference between “nothing happened to this car” and “we never received that record” — both of the big two say as much in their own help pages. Most of what is on this page comes from complete federal registers, so we can tell you which is which, row by row.

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.
