Recalls

3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Engine & cooling Vehicle recall #21V234000 · 2021 · 12,943 vehicles

What's wrong: Nissan north america, Inc. (Infiniti) is recalling certain 2021 Infiniti q50 and q60 vehicles. After detecting rapid acceleration, the engine control module (ECM) May incorrectly reduce engine power and reduce fuel supply to the engine.

Why it matters: A lack of fuel May cause an engine stall, increasing the risk of a crash.

The fix: Infiniti will notify owners, and dealers will reprogram the ECM software, free of charge. The recall began on May 25, 2021.

Suspension, Steering Vehicle recall #21V402000 · 2021 · 14,276 vehicles

What's wrong: 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.

Why it matters: 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

What's wrong: Nissan north america, Inc. (Nissan) is recalling certain 2021 infinity q50, q60, and qx80 vehicles. 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."

Why it matters: 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.
