2021 Infiniti Q50 recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
3 safety recalls, most serious first
1. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. The front steering knuckle or rear axle housing may have insufficient strength due to improper heat-treatment.
What could happen: 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.
The fix: 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.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2021 Q50.
- Book a repair at any authorized Infiniti dealer. Quote NHTSA campaign 21V402000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-867-7669.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

2. Backup camera
What's wrong, in plain English: The rear camera may not show an image when reversing. A software error may deactivate the audio/video control unit screen, preventing the rear-view image from displaying. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
What could happen: A rear-view camera that does not display an image reduces the driver's rear view, increasing the risk of a crash.
The fix: Dealers will update the control unit software, free of charge. Owner notification letters were mailed September 14, 2021. Owners may contact Nissan customer service at 1-800-867-7669. Nissan's number for this recall is R21A9.
