On the 2013-2021 Nissan Sentra, the 2013-2021 Sentra uses the Jatco CVT7 (JF015E) transmission which is prone to premature failure, shuddering, and overheating. Nissan extended the CVT warranty to 10 years/120,000 miles under Customer Service Initiative P8242. The transmission can fail as early as 60,000 miles. Common failure modes include belt slipping, valve body failure, and bearing wear.

This issue also affects: Acura TL, Infiniti QX60, Mitsubishi Outlander

Common Symptoms

Shuddering during acceleration
Transmission slipping or jerking
Delayed engagement from stop
Whining or buzzing noise
CVT overheating warning
Loss of power at highway speeds

How to Fix

Check if covered under Nissan CVT warranty extension (10yr/120k miles). Have CVT fluid changed every 30,000 miles with Nissan NS-3 fluid. If shuddering, valve body replacement may help ($1,500-2,500). Complete CVT replacement costs $3,500-5,000. Avoid aggressive acceleration to prolong CVT life.

On the 2013-2022 Nissan Sentra MR20DD, the B17 and B18 Sentra with the MR20DD engine is prone to premature catalytic converter failure, often before 100,000 miles. The converter substrate breaks down, triggering P0420 efficiency codes. Contributing factors include the direct injection engine's tendency to produce more particulates, short trip driving cycles that prevent the converter from reaching full operating temperature, and catalytic converter theft (the Sentra's low ground clearance makes it an easy target).

This issue also affects: BMW 5 Series, BMW 6 Series, BMW 7 Series

Common Symptoms

Check engine light with P0420
Reduced acceleration
Sulfur smell from exhaust
Failed emissions test
Rattling from under vehicle

How to Fix

Replace the catalytic converter. OEM replacements cost $800-1,400. Aftermarket CARB-compliant converters are available for $250-500. Install a catalytic converter shield/cage ($150-300) to deter theft. Ensure the engine is running properly with no misfires or rich conditions that could damage the new converter.
