Suspension issue
SUSPENSION:REAR:AXLE:SPINDLE
Nissan North America, Inc. (Nissan) is recalling certain 2020 Nissan Murano, INFINITI QX60, 2021 Nissan GT-R, INFINITI QX50, and Q50 vehicles. The front steering knuckle or rear axle housing may have insufficient strength due to improper heat-treatment.
Consequence
The steering knuckle or rear axle could deform upon impact, such as from hitting a curb, resulting in a loss of steering control, or possible wheel separation. Both of these conditions can increase the risk of a crash.
Full campaign recordRemedy
Dealers will inspect and replace the front steering knuckle and rear axle housing, as necessary, free of charge. Owner notification letters were mailed July 26, 2021. Nissan owners may contact customer service at 1-800-867-7669. INFINITI owners may contact customer service at 1-800-662-6200.

Engine issue
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.
Consequence
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.
Full campaign recordRemedy
Dealers will reprogram the engine control module (ECM) software, free of charge. Owner letters were mailed April 8, 2026. Owners may contact Nissan's customer service at 800-647-7261 or Infiniti's customer service at 1-800-662-6200. Nissan's numbers for this recall are R25A8/A9 and R25B1/B2.

What the ratings mean
NHTSA gives the 2021 Infiniti QX50 5 out of 5 stars overall, level with the 5-star median for the 7 comparable 2021 vehicles NHTSA rated in this class.
NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.
NHTSA's dynamic test put this vehicle's rollover probability at 14.7% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

How this compares
At 26 MPG combined, the 2021 Infiniti QX50 ranks 3rd of 8 small SUVs (2WD) EPA rated for 2021 — 1 MPG better than the 25 MPG median for that group.
That places it a little above the middle of its class. Fuel cost is close enough to its rivals that other running costs will probably matter more.
EPA puts annual fuel spend at about $2,900, $125 more than the $2,775 typical for the class. Over five years at 15,000 miles a year that is roughly $14,500, a $625 difference against a class-median vehicle.
Tailpipe CO₂ is 349 grams per mile — about 5.2 metric tons over 15,000 miles of driving.
