2020 Infiniti QX50

No clear pattern

0% of complaints about the 2020 Infiniti QX50 arrived in its first year of service. That is an unusual figure for a 2020 vehicle, but with only 47 complaints on record the sample is too small to call it a pattern — the margin of error covers the range where ordinary vehicles sit. The figures below are reported without a verdict. The most-reported system is engine (17 complaints), typically at 6.2 yr or about 108,000 miles.

Complaints: 47
Median age at failure: 4.5 yr
Median mileage: 5,300 n=9
Crash / fire / tow: 2.1% of reports
Safety recalls: 2

Engine and engine cooling:engine:hard parts internal/mechanical

Nissan North America, Inc. (Nissan) is recalling certain 2021-2024 Rogue, 2019-2020 Altima, 2019-2022 Infiniti QX50, and 2022 Infiniti QX55 vehicles equipped with 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines. The engine bearings may have manufacturing defects that can lead to engine failure.

Engine failure increases the risk of a crash. A bearing failure may cause a breach in the engine block, allowing hot oil to be discharged, increasing the risk of an engine fire.

Tires

Nissan North America, Inc. (INFINITI) is recalling certain 2020 INFINITI QX50 vehicles. The text of the Tire and Loading Information placard, including the tire size and loading capacity, may be illegible. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."

Illegible tire size or loading capacity information can lead to the incorrect sized tire being installed or its overloading, increasing the risk of a crash.

Engine mileage not reported 5.7 yr in service

Pulled out into an intersection with limited visibility. Once I got into my lane I observed a car behind me that I had not seen. I tried to accelerate to avoid being hit. My car began making a knocking sound with loss of power. The other car went around me on the shoulder to avoid a collision. Infiniti of Birmingham (Alabama) says that one of the bearings in the engine spun and there is metal shavings in the oil pan. They say I need a new engine with only 68,000 miles. They are âunsureâ if Infiniti will warranty the cost of repairs. Absolutely ridiculous! Please help!

Engine mileage not reported 1.9 yr in service

The vehicle's engine light turned on. The engine light remains on, and frequently the Malfunction and System fault See Owners Manual will display. When the malfunction message appears all the traction lights are also turned on. The RPM's in the vehicle are very accelerated, and it's difficult to drive the vehicle. The vehicle will also produce a very heavy smog smell. I took the vehicle into the retailer several times and nothing was done. The manufacturer is also not taking responsibility and stated the issue is unrelated to the engine bearing recall.

Engine mileage not reported 6.2 yr in service

Crest Infiniti staff, including Service Rep Trevor and Manager Randy Nadors, misrepresented Recall 25V437 as "not a safety recall" and claimed repairs were stopped until year-end. This contradicts NHTSA"s designation of 25V437 as a serious safety recall and Infiniti Corporate's confirmation. Their false statements indicate a failure to disclose material safety information and unsatisfactory service, thereby putting consumers at risk.

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
