Keeping Your 2018 Nissan Altima Running Smoothly
The 2018 Nissan Altima, part of the vehicle's fifth generation (L33, 2013-2018), is a popular choice for its balance of fuel efficiency, comfortable ride, and reliable performance. To ensure your Altima continues to deliver on these promises for years to come, adhering to a consistent and comprehensive maintenance schedule is crucial. This guide, written by an ASE-certified master technician, will outline the factory-recommended service intervals, discuss common issues specific to this generation, detail severe-duty adjustments, provide typical service costs, and highlight important recall information.
Factory Service Intervals: Staying on Schedule
Nissan's maintenance schedule is designed to optimize the longevity and performance of your 2018 Altima. The intervals provided below are for normal driving conditions. Always refer to your owner's manual for the most precise details and specific recommendations for your vehicle's trim and engine configuration (primarily the 2.5L 4-cylinder or the 3.5L V6).
| Service Item | Interval (Miles) | Interval (Months) | Notes |
|---|---|---|---|
| Engine Oil & Filter | 5,000 | 6 | Use Nissan Genuine Ester Oil or equivalent API certified 5W-30 (2.5L) or 0W-20 (3.5L) synthetic blend or full synthetic. This is a critical service for engine health. |
| Tire Rotation | 5,000 | 6 | Essential for even tire wear and extending tire life. Check tire pressure at this time. |
| Inspect Brakes | 5,000 | 6 | Check brake pads, rotors, calipers, and fluid level. |
| Inspect Fluids | 5,000 | 6 | Check all fluid levels (coolant, power steering if applicable, brake, washer) and condition. |
| Multi-Point Inspection | 5,000 | 6 | Comprehensive check of belts, hoses, steering, suspension, exhaust, lights, etc. |
| Cabin Air Filter | 10,000 | 12 | Replace more frequently in dusty or polluted environments. |
| Engine Air Filter | 15,000 | 18 | Critical for engine performance and fuel economy. Replace more often if driving in dusty conditions. |
| Brake Fluid | 20,000 | 24 | Replace with DOT 3 brake fluid. Important for braking system integrity and preventing corrosion. |
| Spark Plugs | 105,000 (2.5L) | 105 | Replace with genuine Nissan or equivalent iridium-tipped spark plugs. Less frequent for 3.5L V6 (typically a bit longer, but consult specific manual). This is a significant factor in engine performance and fuel economy. |
| Coolant | 105,000 | 105 | Initial replacement at 105,000 miles or 105 months, then every 75,000 miles or 75 months. Use Nissan Long Life Antifreeze/Coolant (blue). Critical for engine cooling and preventing corrosion. |
| CVT Fluid | 60,000 | 60 | Critical for the Altima's Continuously Variable Transmission (CVT). Use Nissan NS-3 CVT Fluid. This is a highly recommended service, especially given common CVT concerns. More frequent replacement (30,000 miles) is advised for severe duty. |
| Accessory Drive Belt | 60,000 – 100,000 | 60 – 100 | Inspect at every service, replace if cracked, frayed, or glazed. There is no timing belt in the 2018 Altima; it uses a timing chain designed for the life of the engine, but it should be inspected if noise or performance issues arise. |
| Fuel Filter | Lifetime | Lifetime | The fuel filter is typically integrated into the fuel pump module and designed for the life of the vehicle. Replacement is generally only necessary if a fuel delivery issue is diagnosed. |
Known Issues and Common Problems for the 2018 Nissan Altima (Fifth Generation L33)
While the 2018 Altima is generally considered reliable, like any vehicle, specific issues can arise. Awareness of these can help you identify potential problems early and address them proactively.
- Continuously Variable Transmission (CVT) Issues: This is perhaps the most widely discussed concern across several Nissan models, including the Altima. Symptoms can include shuddering, jerking, hesitation, loss of power, or complete transmission failure. While Nissan has made improvements to their CVTs, regular fluid changes (especially under severe driving conditions) are paramount to its longevity. Ignoring early signs can lead to costly repairs or replacement.
- Rear Suspension Noise: Owners have reported clunking or thumping noises from the rear suspension, often attributed to worn sway bar bushings or end links. This is typically a relatively inexpensive fix.
- HVAC Blower Motor Failure: Some owners have experienced issues with the blower motor, leading to reduced or no airflow from the heating and air conditioning system. This usually manifests as a noisy blower or no air at all on certain settings.
- Infotainment System Glitches: Occasional freezing, unresponsiveness, or connectivity issues with the infotainment system (Bluetooth, USB) have been reported. Often, a simple system reset (refer to owner's manual) or software update can resolve these.
- Battery Drain Issues: While less common, some owners have reported unexplained battery drain, which can be challenging to diagnose without professional help. It could stem from a variety of sources, including faulty electrical components or parasitic draws.
