Whether any of this applies to one specific QX50
A campaign covers a build range, not a model year, so two identical-looking cars from 2019 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Infiniti 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 2019 Infiniti QX50, 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 2019 Infiniti QX50. The contact stated while driving 60 MPH, the vehicle started to decelerate independently. The contact stated no warning light was illuminated. The contact was able to park on the side of the road and called the dealer to make them aware of the failure.
After multiple related incidents, I am compelled to make a report. My car just displayed red and white flashing indicators on the dash and automatically screeched to a halt, completely out of my control, in the middle of a busy intersection. Because the road was damp from rain, my car actually skidded.
On may 4, 2019, I tool delivery of a new infinity, Qx50 and after 2.5 months of ownership (july 26, 2019 to present), i'm having ongoing / unresolved problems / failures with; audio, lane departure, collision warning w/ sudden stopping, heated / cool seats, infotainment, audio, tailgate, remote door locks, both screens going blank, phone…
The contact owns a 2019 Infiniti Qx50. The contact stated while driving at 65 MPH, there was a loud, abnormal popping sound coming from the vehicle. Soon after the popping sound was heard, a bright flashed from the instrument panel. The instrument panel went blank had gone blank with a blue streak across the screen.
Car would not drive upon pressure of the gas pedal placing driver in immediate danger. Driver pulled over multiple times, shifted car into park and turned car off, proceeded to attempt to drive again. After fourth time, the transmission/engine responded.
My 2019 Infiniti Qx50 FWD has been wasting a lot of fuel compared to what is/was advertised on the window sticker. I leased the vehicle expecting the gas mileage to be somewhere between 24 and 31 mpg's, but in reality I have been experiencing 17 - 20 MPG.
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 Infiniti itself: 5 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 5 injured, as claimed, not verified — about 13 per 100,000 built. Every QX50 model year, by year and system → Dated and by system, they are exhibit F of the defect dossier.
When owners reported it
miles, typically
Half the 51 owner reports with an odometer reading on file fall between 7,000 and 94,000 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.
Median mileage by component
| Component | Reports | Median miles | Vs same age |
|---|---|---|---|
| Engine | 28 | 82,000 | 1.95× |
Vs same age is this model year’s median for the system divided by the median of every 2019-model-year complaint about the same system, all makes: under 1× means owners of this car reported it at lower mileage. Here, owners reported later: engine (1.95×). Which systems go early across the whole fleet: the component study.
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.

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 2019 Infiniti QX50 failed the emissions check on 3.1% of first inspections — close to the 2.7% for every 2019 model-year vehicle inspected; and the safety inspection on 1.6% (every 2019 vehicle: 1.7%).

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 2019 vehicle” is every 2019 model-year car, SUV and pickup inspected in the same window, all makes.

QX50 by model year
all years, side by side →Common questions about the 2019 QX50
Source: EPA, NHTSA and manufacturer press kitsDoes the 2019 Infiniti QX50 have any recalls?
NHTSA has posted 3 recall campaigns for the 2019 Infiniti QX50, 1 of them rated critical. The most serious on file is 25V437000, covering Engine And Engine Cooling. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2019 Infiniti QX50?
NHTSA gave the 2019 Infiniti QX50 5 stars overall in its New Car Assessment Program tests — 5-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it C (76/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2019 Infiniti QX50?
Across the 2 EPA-rated configurations of the 2019 Infiniti QX50, 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 2019 Infiniti QX50?
Transport Canada measured it at 185.0 in long, 75.2 in wide (body, without mirrors), 66.1 in tall, on a 110.2 in wheelbase. Curb weight: 4,173 lb. Those are its measurements of the North American versions; every figure is in the table above.
What do owners complain about on the 2019 Infiniti QX50?
Owners have filed 145 complaints with NHTSA about the 2019 Infiniti QX50, most often about engine, forward collision avoidance, unspecified. Of those, 5 involved a crash, 1 a fire, 3 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 2019 Infiniti QX50?
The EPA smog rating for the 2019 Infiniti QX50 is 5 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 ULEV70, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2019 Infiniti QX50?
The manufacturer has filed 172 service bulletins and related communications with NHTSA for the 2019 Infiniti QX50, most often covering equipment, electrical system, engine. The most recent is dated 2026-08-26. 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 2019 Infiniti QX50 do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2019 Infiniti QX50 failed the emissions check on 3.1% of first inspections — close to the 2.7% for every 2019 model-year vehicle inspected; and the safety inspection on 1.6% (every 2019 vehicle: 1.7%). 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.
