Common OBD2 Codes
| Code | Frequency | Notes |
|---|---|---|
| P0325 | Very Common | Knock sensor failure, common on VG33E engines due to sensor location and heat exposure |
| P0420 | Common | Catalytic converter efficiency below threshold, often caused by O2 sensor failure or actual cat degradation |
| P0171 | Common | System too lean (Bank 1), typically caused by vacuum leaks or dirty MAF sensor |
| P0138 | Common | O2 sensor circuit high voltage (Bank 1, Sensor 2), common failure on higher mileage vehicles |
| P1320 | Occasional | Nissan-specific code for ignition control signal error, often related to distributor issues on KA24DE |
| P0300 | Occasional | Random/multiple cylinder misfire, can be caused by ignition coils or spark plug issues |
| P0401 | Occasional | EGR flow insufficient, often due to carbon buildup in EGR passages |
Known Problems
The timing chain tensioner on the VG33E engine can wear out, causing a rattling noise on cold starts. If left unaddressed, the chain can skip or break, causing catastrophic engine damage. The tensioner should be replaced along with guides and the chain if excessive wear is present.
Typical mileage: 120,000-180,000 miles
Shop parts for this repairStrawberry Milkshake of Death (SMOD) occurs when the internal transmission cooler in the radiator fails, allowing coolant to mix with transmission fluid. This causes transmission failure if not caught early. Check coolant regularly for pink/red contamination.
Typical mileage: 90,000-150,000 miles
Shop parts for this repairThe knock sensor on VG33E engines is located under the intake manifold and commonly fails due to heat and vibration. Symptoms include poor performance, reduced fuel economy, and difficulty passing emissions. Requires intake manifold removal for replacement.
Typical mileage: 100,000-150,000 miles
Shop parts for this repairCast iron exhaust manifolds on both KA24DE and VG33E engines are prone to cracking, especially at the collector area. This causes exhaust leaks, ticking noises, and can affect O2 sensor readings. Aftermarket headers are a common upgrade/replacement.
Typical mileage: 80,000-120,000 miles
Shop parts for this repairThe fuel level sender in the gas tank commonly fails, causing erratic or inaccurate fuel gauge readings. The gauge may stick, fluctuate wildly, or read empty when there's fuel in the tank. Requires fuel tank removal for replacement.
Typical mileage: 100,000-180,000 miles
Shop parts for this repairThe distributor shaft bearings on the KA24DE engine wear out over time, causing rough idle, misfires, and difficulty starting. The distributor housing can also develop cracks. Rebuilding or replacing the distributor is necessary.
Typical mileage: 150,000-200,000 miles

The fuel gauge may provide inaccurate readings due to a faulty fuel level sensor, potentially causing the vehicle to run out of fuel unexpectedly.
The front seat belt webbing may fray and separate, reducing restraint effectiveness in a crash.

Common OBD2 Codes
| Code | Frequency | Notes |
|---|---|---|
| P0420 | Very Common | Catalytic converter efficiency below threshold, very common on VQ40DE engines after 100k miles |
| P0171 | Common | System too lean (Bank 1), commonly caused by vacuum leaks or MAF sensor contamination |
| P0174 | Common | System too lean (Bank 2), same causes as P0171 on V6 engines |
| P0455 | Common | EVAP system large leak detected, often a loose gas cap or cracked EVAP canister |
| P0340 | Occasional | Camshaft position sensor circuit malfunction, can be caused by sensor failure or wiring issues |
| P0101 | Occasional | Mass airflow sensor circuit range/performance, usually requires MAF cleaning or replacement |
Known Problems
Similar to first generation, the 2005-2010 Frontiers are notorious for internal transmission cooler failure in the radiator. This allows coolant and ATF to mix, destroying the transmission. Nissan extended warranty coverage on some VINs. Installing an external transmission cooler and bypassing the internal one is highly recommended.
Typical mileage: 90,000-130,000 miles
Shop parts for this repairThe VQ40DE engine is known for timing chain stretch, especially on 2005-2010 models. Symptoms include a rattling noise on cold starts that disappears when warm. Severe cases can cause timing issues and engine damage. The chain, tensioners, guides, and VVT gears should all be replaced together.
Typical mileage: 80,000-150,000 miles
Shop parts for this repairThe charcoal EVAP canister can crack or develop leaks, especially in areas with temperature extremes. This triggers P0455 and P0456 codes and can cause fuel odors. The canister is located behind the rear bumper and is relatively expensive to replace.
Typical mileage: 100,000-160,000 miles
Shop parts for this repairThe rear differential pinion seal and axle seals commonly leak differential fluid, especially on 4WD models. This can contaminate brake components and lead to differential damage if fluid levels get too low. Regular inspection and timely replacement is important.
Typical mileage: 60,000-120,000 miles
Shop parts for this repairOn 4WD models, the front differential oil cooler lines can crack or corrode, causing differential fluid leaks. These lines run along the frame and are exposed to road debris and salt. Leaks can lead to differential failure if not addressed.
Typical mileage: 80,000-140,000 miles
Shop parts for this repairThe steel transmission cooler lines that run to the radiator can corrode and develop leaks, especially in salt-belt states. This causes transmission fluid loss and potential transmission damage. Replacing with stainless or coated lines is recommended.
Typical mileage: 100,000-180,000 miles
Shop parts for this repairSimilar to the first generation, the fuel level sender can fail causing erratic gauge readings. The fuel gauge may stick at full, empty, or fluctuate randomly. This is a common issue across all D40 years.
Typical mileage: 90,000-150,000 miles
Shop parts for this repairThe camshaft position sensors on the VQ40DE can fail, causing rough running, stalling, or no-start conditions. The sensors are relatively inexpensive but can be difficult to access on some model years.
Typical mileage: 100,000-180,000 miles

The secondary hood latch release may not function properly, allowing the hood to open while driving if the primary latch is not engaged.
The fuel pressure sensor O-ring may leak, potentially causing fuel odor or fuel leakage, increasing fire risk.
The backup camera image may not display properly when the vehicle is shifted into reverse, reducing rear visibility.

Common OBD2 Codes
| Code | Frequency | Notes |
|---|---|---|
| P0420 | Occasional | Catalytic converter efficiency below threshold, less common on newer vehicles but can occur |
| P0300 | Occasional | Random misfire detected, rare but has been reported on some early 2022 models |
| P0456 | Occasional | EVAP system small leak detected, sometimes caused by loose gas cap on newer models |
| P0171 | Occasional | System too lean (Bank 1), uncommon but can be caused by MAF sensor issues |
Known Problems
Some 2022-2023 models have experienced intermittent infotainment system freezing, slow response, or failure to connect with smartphones. Software updates from Nissan have addressed many of these issues. The system may require a hard reset or dealer software update.
Typical mileage: 0-30,000 miles
Shop parts for this repairEarly 2022 models with the 9-speed automatic transmission have reported occasional harsh shifts or delayed engagement. Nissan has released transmission software updates to improve shift quality and logic.
Typical mileage: 0-20,000 miles
Shop parts for this repairSome owners have reported that the backup camera image quality is poor in low-light conditions, making it difficult to see clearly at night. This appears to be a limitation of the camera hardware rather than a defect.
Typical mileage: 0-50,000 miles
Shop parts for this repairSome owners have reported excessive paint chipping on the hood and front bumper, particularly on Pro-4X models used off-road. This may be related to paint thickness or adhesion. Clear protective film installation is recommended.
