The 2021 INFINITI Q50 has 4 recalls, the most serious being two structural and mechanical issues: a software fault that can cut engine power and stall the car in traffic, and a steering knuckle or rear axle housing that can deform or allow a wheel to separate after hitting a curb.
The engine control module can misread rapid acceleration and incorrectly cut fuel to the engine, causing it to stall without warning while driving. On the chassis side, the front steering knuckle or rear axle housing may lack sufficient strength, meaning a curb strike or similar impact can deform the part, causing a loss of steering control or, in the more serious outcome, a wheel separating from the vehicle entirely. Both of these issues carry real potential for a crash with little opportunity for the driver to react.
The remaining two recalls both point to the same underlying problem: a software fault can cause the center display screen to go dark when the vehicle starts, taking the rearview camera image with it. When the screen fails to come on, the camera shows nothing when reverse gear is selected, leaving the driver without the rear view the camera is meant to provide. Prior repair attempts did not fully resolve the issue, which is why separate filings exist for this defect. Owners who had the screen software addressed previously may find the problem persists.
