What the record shows

Written from this model’s own complaint and recall history.

Three QX50 model years have completed the 60-month window, and all three are small files: 60, 19 and 26 complaints. Read the grades with that in mind — at these counts a dozen reports is the difference between a B and an F, and the 2019 car’s F rests on 60 reports rather than on a large body of evidence.

What the record does show is consistent. Driver assistance leads the 2019 car at 15 reports and the 2020 car at 9, and the accounts describe automatic emergency braking applying itself with nothing ahead — several owners report it happening more than once, on open road. Braking sits second on the 2019 car with more of the same accounts filed under a different heading, so the group is larger than either category alone.

2019 opens the second generation of this model. Its median odometer reading at complaint is 7,400 miles, and the 2020 car’s is 2,000, so these arrive early rather than through wear.

The direction afterwards is good. The 2020 car sits at 0.71 times the model’s own median with no crash or fire allegations, and the 2021 car records 26 complaints with engine leading rather than driver assistance.

Seven recall campaigns across the model, and the QX50 carries an overall B.

P — provisional. These years have not completed 60 months on the road, so their totals are incomplete and they are excluded from the verdict.

Recall work is free at any franchised dealer, whoever owns the car and however old it is. Check a specific car’s VIN on NHTSA’s register before you buy — an unrepaired campaign is among the most commonly missed items on a used vehicle.

How long do they last?

Complaint records show when problems get reported, not how long a car survives. Where owners gave an odometer reading, faults on the 2019 were reported at a median of 7,400 miles. Treat that as the point problems start being noticed, not a lifespan.

Common questions

What is the best year for the Infiniti QX50?

How many recalls does the Infiniti QX50 have?

How this was calculated

Every model year is scored over an identical window: complaints filed with NHTSA during the first 60 months after that model year went on sale. Without this, older cars look worse purely because they have had longer to accumulate reports.

Limitations. Complaints are unverified reports submitted voluntarily by owners; they are allegations, not findings, and reporting rates vary between models. Model years with fewer than 60 months on the road are marked provisional and excluded from verdicts. Cross-model comparison is withheld pending production-volume data.
