All 2 Known Issues
On the 2007-2012 Nissan Sentra QR25DE, the 6th generation Sentra with the 2.5L QR25DE engine is known for excessive oil consumption, often burning 1 quart every 1,000-2,000 miles. The issue is caused by worn piston rings and valve stem seals. The QR25DE engine design has tight piston ring tolerances that contribute to oil passing into the combustion chamber. Nissan performed an oil consumption test for warranty claims but many vehicles were out of warranty when the issue became severe.
Common Symptoms
- Oil level low between changes
- Blue smoke from exhaust on startup
- Oil consumption of 1 quart per 1,000-2,000 miles
- Fouled spark plugs
- Rough idle from oil-fouled plugs
How to Fix
Monitor oil level and top off between changes. For a permanent fix: piston ring replacement ($1,500-2,500) or engine rebuild ($2,500-4,000). Switching to a slightly thicker oil weight (5W-30 vs 5W-20) may reduce consumption slightly. Some owners have had success with high-mileage oil formulations that condition seals. Engine replacement with a used low-mileage unit is sometimes more cost-effective ($1,500-2,500 installed).

On the 2007-2019 Nissan Sentra, the Sentra MAF sensor is prone to contamination and failure, causing driveability issues. Oil from aftermarket air filters (especially oiled cotton filters) or crankcase ventilation can coat the hot wire element, causing incorrect air flow readings. This leads to poor fuel mixture calculations, hesitation, and stalling. Even with stock air filters, the MAF sensor can fail due to age and heat cycling.
Common Symptoms
- Hesitation during acceleration
- Engine stalling at idle
- Poor fuel economy
- Check engine light with P0101 or P0102
- Rough idle
How to Fix
First attempt: Clean the MAF sensor with dedicated MAF sensor cleaner spray ($8-12). Do NOT use carburetor cleaner or brake cleaner as they can damage the sensor. If cleaning does not resolve the issue, replace the MAF sensor ($80-150 for aftermarket, $150-250 OEM). The sensor is located in the intake tube between the air filter and throttle body and takes 10 minutes to replace.
