2025 Nissan Sentra Transmission Defect Could Lead to Loss of Drive Power

Owners of certain 2025 Nissan Sentra vehicles should be aware of a newly identified transmission defect that could result in a sudden loss of drive power and an increased risk of a crash. The issue involves the connection between the front left driveshaft and the vehicle's Continuously Variable Transmission (CVT) and, while uncommon, has the potential to create serious safety concerns if left unaddressed.

What Is the Problem?

According to Nissan, certain 2025 Sentra vehicles may have a front left driveshaft that was not fully seated into the CVT assembly during production. This manufacturing error was traced to a supplier tooling problem that affected a limited production run.

If the driveshaft is not fully engaged with the transmission, the connection to the differential gear may eventually fail. Should that happen, the vehicle could suddenly lose the ability to transfer power to the wheels, leaving the driver without propulsion.

Additional Safety Concern

The defect presents another important safety risk. If the left driveshaft becomes disengaged from the CVT while driving, the vehicle may move even after the driver shifts into Park. If the parking brake has not been applied, the vehicle could roll unexpectedly, increasing the risk of property damage, injury, or a collision.

For this reason, drivers should always apply the parking brake whenever parking their vehicle, particularly if they suspect any transmission-related issues.

Possible Warning Signs

Some vehicles may provide warning symptoms before complete failure occurs. Owners should pay attention to:

• Illumination of the Malfunction Indicator Lamp (MIL) or Check Engine Light
• Transmission fluid leaking beneath the vehicle
• Transmission hesitation during acceleration
• Jerking or rough operation while driving
• Reduced transmission fluid pressure

While these symptoms do not necessarily mean the defect is present, they should be inspected promptly by a qualified technician.

What Caused the Problem?

Nissan determined the issue was caused by a supplier production tooling error that prevented the front left driveshaft from being fully installed into the CVT assembly on certain vehicles.

Based on production and supplier records, Nissan states that the defect is limited to specific 2025 Nissan Sentra vehicles built during a defined manufacturing period. No other Nissan or INFINITI models are believed to be affected.

How Will Nissan Fix It?

To correct the problem, Nissan dealers will:

• Inspect the front left driveshaft for proper installation.
• Replace the driveshaft if necessary.
• Replace the CVT assembly when inspection indicates damage or improper engagement.

Owner Notifications

Owner notification letters are expected to begin mailing on August 5, 2026.
