The complete Hyundai Tucson maintenance schedule for the NX4 4th generation — all three powertrains covered, confirmed OEM part numbers, severe-condition adjustments, and what every Hybrid and PHEV owner needs to know about their unique service items.
The Hyundai Tucson maintenance schedule for the NX4 4th generation covers one of the most popular compact SUVs in America — and one of the most misunderstood when it comes to DIY maintenance. The 4th gen Tucson launched for 2022 with three distinct powertrains, each requiring different OEM parts. Getting the wrong oil filter for your Hybrid is a surprisingly common mistake that forums are full of.
This guide covers every powertrain, every interval, and every confirmed OEM part number — so you can maintain your Tucson correctly whether you own the base 2.5L, the fuel-efficient Hybrid, or the Plug-in Hybrid with its EV range and additional battery system service requirements.
NX4 is Hyundai's internal chassis code for the 4th generation Tucson covering 2022–2025 in North America. It helps confirm you have the right OEM parts — the 3rd gen TL (2016–2021) uses different oil filters, air filters, and spark plugs. If you see NX4 in your VIN documentation or on forums, you're in the right place.
Hyundai Tucson Maintenance Schedule 2022–2025 at a Glance
Factory-recommended service intervals for all 2022–2025 Tucson NX4 models under normal driving conditions. Hyundai's recommended oil change interval is every 7,500 miles or 12 months. Under severe conditions — short trips, extreme temperatures, dusty environments — shorten to 5,000 miles. See the severe conditions section for the full breakdown.

Tucson NX4 Oil Change Guide by Powertrain
The most important thing to know before your first DIY oil change on the NX4 Tucson: the gas and hybrid/PHEV models use different oil filters. The 2.5L GDI and the 1.6T HEV/PHEV use completely different filter housings. Using the wrong filter is one of the most common mistakes on Tucson forums — and in some cases dealers make the same error. Confirm your powertrain first.
Plug-in Hybrid Tucson owners who drive primarily on electric power may be tempted to skip oil changes since the engine runs less. Do not extend oil change intervals regardless of electric mileage. The 1.6T engine in the PHEV still accumulates moisture and combustion byproducts in the oil even during short gas engine cycles. Change oil every 7,500 miles or 12 months — whichever comes first — and use a calendar reminder if your electric mileage is high.
Spark Plugs: Interval & OEM Part Numbers
The 2022–2025 Tucson uses iridium spark plugs across all gasoline-powered variants with a 60,000-mile replacement interval. The 2.5L GDI and 1.6T turbo engines use different plugs — confirm your engine before ordering. Iridium plugs are pre-gapped from the factory; do not attempt to adjust the gap.
| Engine | Models | OEM Part # | NGK Cross | Interval | Qty |
|---|---|---|---|---|---|
| 2.5L GDI (Gas) | SE · SEL · XRT · N Line · Limited | 1887508085 | NGK SILZKR8J | 60,000 mi | 4 |
| 1.6T HEV (Hybrid) | Blue · SEL Conv. · N Line · Limited HEV | Confirm by VIN | Confirm by VIN | 60,000 mi | 4 |
| 1.6T PHEV | SEL PHEV · Limited PHEV | Confirm by VIN | Confirm by VIN | 60,000 mi | 4 |
The 1.6T turbo hybrid engines use a different spark plug from the 2.5L GDI. The OEM part number for the Hybrid/PHEV variants is best confirmed directly via your VIN at a Hyundai parts counter or at hyundaiusa.com parts lookup — the 1.6T turbo plug spec has had some part number updates across model years. The 2.5L GDI part 1887508085 (NGK SILZKR8J) is confirmed across 2022–2025 for the gas-only Tucson.

Engine Air Filter & Cabin Air Filter
Engine Air Filter — 28113-P0400
Replace every 30,000 miles under normal conditions. If you drive on dusty roads, near construction, or in high-pollen areas, inspect at 15,000 miles and replace sooner as needed. Hyundai's official recommendation from the NX4 owner's manual is to replace more frequently under severe conditions — a clogged filter noticeably impacts both performance and fuel economy on the turbocharged 1.6T models.
OEM part 28113-P0400 fits all 2022–2025 Tucson NX4 models — 2.5L GDI, 1.6T HEV, and 1.6T PHEV. One part number for all three powertrains makes this the easiest filter to order.
Cabin Air Filter — 97133-N9100
Replace every 15,000 miles or annually, whichever comes first. Located behind the glove box and installs without tools in about 5 minutes. Signs it's overdue: reduced airflow from vents, musty odor with the AC running, or visible gray/brown discoloration when removed.
OEM part 97133-N9100 fits all 2022–2025 Tucson NX4 models regardless of powertrain. If you spend time in heavy traffic, near wildfires, or in highly polluted urban environments, consider replacing annually regardless of mileage.
Tucson Plug-in Hybrid (PHEV) Maintenance
The Tucson PHEV adds a larger 13.8 kWh battery pack to the 1.6T hybrid system, enabling approximately 33 miles of all-electric range (EPA estimated). This makes it the most environmentally flexible Tucson — but it also adds the most service complexity, particularly around the high-voltage battery system and charge port.
Beyond the Standard Hybrid Schedule
These items apply to the PHEV only, on top of the Hybrid additional services above.
One important reminder for PHEV owners with high electric mileage: your engine oil still degrades on a calendar basis even if the combustion engine rarely runs. Oil absorbs moisture and oxidizes over time regardless of mileage. Never skip an oil change simply because you've driven mostly on electric power — follow the 12-month calendar interval as a minimum, even if mileage is low.
Hyundai Tucson NX4 OEM Part Numbers 2022–2025
All confirmed OEM part numbers for the 4th gen Tucson. Using genuine Hyundai parts ensures proper fit, maintains your warranty, and avoids compatibility issues — especially important on the hybrid and PHEV models where incorrect parts can affect battery management calibration.

Tucson Severe Condition Maintenance Schedule
Hyundai defines severe driving conditions as any combination of: frequent short trips under 5 miles, extreme hot or cold climates, dusty or off-road environments, stop-and-go city traffic, or towing. If your daily driving falls into these categories, the standard 7,500-mile schedule is not sufficient.
| Service Item | Normal Interval | Severe Interval |
|---|---|---|
| Engine Oil & Filter | 7,500 mi / 12 mo | 5,000 mi / 6 mo |
| Engine Air Filter | 30,000 mi | 15,000 mi or per inspection |
| Cabin Air Filter | 15,000 mi / 1 yr | 12,000 mi or per inspection |
| Brake Fluid | Every 3 years | Every 2 years |
| Transmission Fluid | Inspect only | Replace at 60,000 mi |
| AWD Rear Differential | Inspect at 30,000 mi | Replace at 30,000 mi |
| Tire Rotation | 7,500 mi | 6,000 mi |
Short stop-and-go trips in cold, wet weather are especially hard on engine oil — moisture from combustion doesn't fully evaporate. If your daily drive is under 10 minutes each way, consider the 5,000-mile severe interval regardless of season. Your oil will thank you.
Tucson Hybrid Maintenance
The Tucson Hybrid pairs a 1.6L turbocharged engine with a 44.2 kW electric motor and a 1.49 kWh lithium-ion polymer battery. The core maintenance schedule mirrors the gas model, but the hybrid system adds several service items that are easy to overlook — and expensive to fix if neglected.
Beyond the Standard Tucson Schedule
These items apply to the 1.6T HEV only and are in addition to standard oil, filter, and tire service.
Tucson Hybrid brake pads typically last significantly longer than gas model pads due to regenerative braking handling most light deceleration. Many owners report 80,000+ miles from the front pads. That said, because friction brakes engage less frequently, rotor surface rust can develop faster — inspect rotors for deep pitting or grooves at each service, even if pads are still thick.
The Hybrid Starter Generator belt on the 1.6T HEV is a unique service item that doesn't exist on the gas model. It drives the HSG unit that integrates the electric motor with the combustion engine. A failed HSG belt can leave you stranded and is not covered under basic service plans. Inspect every 30,000 miles and replace at the first sign of cracking or glazing.
