What this means for owners
- The single documented complaint centers on a P0401 fault (EGR flow insufficient) with accompanying poor acceleration. While this points toward the exhaust gas recirculation (EGR) system in that case, the data does not establish a widespread pattern for the entire model year range. No official recalls are listed here, so there isn’t a nationwide safety recall currently tied to these exact reports in the provided record.
- Given the limited dataset, many other common Altima issues known anecdotally by owners or discussed in broader automotive literature are not represented here. The practical guide below combines what’s suggested by the provided data with broad, generally accepted knowledge about 2013–2018 Altimas.
Common problems by system (practical overview)
Emissions and EGR/engine performance (P0401-type issues)
What tends to happen
- P0401 and related EGR concerns typically involve reduced EGR flow, which can cause rough idle, reduced power, and poorer acceleration.
- In many cases, carbon buildup in the EGR passages or a faulty EGR valve/solenoid is involved. A clogged EGR circuit can trigger the check engine light and degrade engine performance.
Likely causes (common scenarios)
- Carbon buildup or slag in EGR passages (most frequent)
- Faulty EGR valve or faulty EGR solenoid or vacuum lines
- Vacuum leaks or related sensor faults that affect EGR operation
- MAF/MAP sensor interaction issues can sometimes amplify symptoms
Typical symptoms you might notice
- Check Engine light on or blinking
- Noticeable drop in acceleration or responsiveness
- Slightly lower fuel economy
- Idle irregularities or roughness
Typical repairs (vary by exact cause)
- Cleaning or replacing the EGR valve
- Cleaning EGR passages and intake routes
- Replacing vacuum lines or the EGR solenoid if defective
- In some cases, replacing the EGR gasket or related components
Estimated costs for 2025 (rough ranges; varies by engine option and labor)
- EGR valve cleaning or minor repair: $100–$300

Transmission and drivetrain (notably CVT reliability)
What tends to happen
- The Altima uses a continuously variable transmission (CVT) on most 2.5L models. CVT-related issues commonly include slipping, shuddering, jerking, delayed or harsh engagement, overheating, and unusual noises.
- Over time, CVTs can wear belts/pulleys or exhibit fluid-related issues that degrade performance.
Likely causes
- Worn CVT belt/chain or internal components
- Low or degraded CVT fluid (level, contamination, or incorrect spec)
- Overheating or prolonged heavy use (city driving, towing, or high ambient temperatures)
- Valve body or transmission control module problems in some cases
Typical symptoms you might notice
- Slipping or delayed acceleration
- Surging or surges in power delivery
- Harsh or abrupt upshifts/downshifts
- Unusual whining or grinding noises from the transmission
- Transmission warning light or check engine light in some cases
Typical repairs
- CVT fluid change or flush with correct Nissan spec fluid
- Fluid pan gasket replacement if leaking
- CVT valve body or other internal component repair/replacement
- In severe cases, CVT replacement or rebuild
Estimated costs for 2025
- CVT fluid change (service): $150–$300
- CVT fluid flush: $250–$450
- CVT repair (valve body, seals, worn components): $1,000–$3,500
- CVT replacement (new or rebuilt unit, installed): $3,000–$5,000+, depending on engine, labor rates, and parts
- Note: If CVT failure is extensive, some owners opt for a used/renovated unit; costs vary widely.
Engine performance and fuel economy (misfires, general efficiency)
What tends to happen
- Misfires or rough running can occur due to ignition or fuel delivery issues, particularly in the 2.5L four-cylinder engines common in this generation.
- Spark plugs, ignition coils, fuel injectors, and vacuum leaks can contribute to poor performance and reduced efficiency.
Likely causes
- Worn or fouled spark plugs and/or ignition coils
- Faulty or dirty fuel injectors
- Vacuum leaks affecting air-fuel ratio
- Mass air flow (MAF) sensor or oxygen sensor faults
Typical symptoms
- Rough idle or engine vibration
- Loss of power or hesitation during acceleration
- Poor fuel economy
- Check Engine light with misfire-related codes (P030x family, P0171/P0174, etc.)
Estimated costs for 2025
- Spark plug replacement (4-cylinder): $150–$350 (labor plus parts)
- Ignition coil replacement (per coil): $60–$180 (parts) plus labor
- Fuel injector cleaning or replacement: $120–$400
- Oxygen sensor replacement: $120–$250
- MAF sensor replacement: $150–$300
- Vacuum leak diagnosis/repair: $100–$300 (varies with extent of leaks)
Electrical and charging/electronics
What tends to happen
- General electrical gremlins can show up as battery charging issues, dead battery symptoms, faulty sensors, or infotainment/controls glitches.

- Wiring/ground repairs (diagnostic plus repair): $100–$500 depending on severity
- BCM/ECU-related diagnostics: $100–$200 (diagnostic fees; replacement varies widely)
Brakes, steering, and suspension
What tends to happen
- Normal wear will affect pads, rotors, and other brake components. Some drivers report ABS-related or wheel-speed sensor-related issues, or roughness in steering and handling with age.
- Steering assistance systems (electric power steering) can display intermittent issues in many modern cars as components age, though not every Altima exhibits this.
Likely causes
- Worn brake pads/rotors
- Worn wheel bearings or hubs
- ABS wheel-speed sensor faults

Typical costs for 2025
- Blower motor replacement: $300–$600
- Climate control module/diagnostics: $100–$250 for diagnostics; parts may vary
Maintenance tips and prevention (practical steps)
- Address check engine lights promptly: When dashboard lights appear, run a diagnostic scan to identify codes (OBD-II). This helps isolate issues like P0401 or misfire codes before they worsen.
- Follow a preventive maintenance schedule: Regular oil changes, air filter changes, and spark plug/coil inspections per owner’s manual. For the CVT, adhere to Nissan’s recommended service intervals for fluid checks and changes (use the specific CVT fluid type Nissan calls for in your engine code).
- Keep the CVT fluid fresh: If your vehicle has signs of CVT strain (slipping, shuddering, or high heat), have the transmission fluid checked and changed by a shop familiar with Nissan CVTs. Avoid aggressive towing or heavy lugging that overheats the CVT.
- Treat the EGR system: If you notice reduced power or rough idle, consider inspecting the EGR valve and passages for carbon buildup and address it before it leads to more complex issues.
- Maintain ignition system: For 2.5L engines, keep spark plugs and ignition coils in good condition to minimize misfires and improve fuel economy.
- Battery and charging care: Test the battery and alternator periodically and replace aging components to prevent electrical bugs.
- Brake and tire care: Inspect and replace pads, rotors, and tires as needed. Listen for abnormal brake noises and address ABS/traction-control warnings promptly.
- Use quality fluids: Do not mix CVT fluids. Use the factory-recommended fluids and follow service intervals.
Data limitations and how to use this guide
