How many air filters does a Lexus RX 350 have?
The Lexus RX 350 typically has two air filters: a cabin air filter and an engine air filter. These filters play a crucial role in maintaining the air quality and performance of the vehicle.
Cabin Air Filter
The cabin air filter is responsible for cleaning the air that enters the vehicle's interior through the heating, ventilation, and air conditioning (HVAC) system. This filter traps dust, pollen, and other airborne particles, ensuring that the air circulating inside the cabin is clean and fresh. The cabin air filter is usually located behind the glove box or in the HVAC system, and it should be replaced periodically, typically every 12-15,000 miles or as recommended by the manufacturer.
Engine Air Filter
The engine air filter is responsible for cleaning the air that enters the engine. This filter helps to protect the engine from dirt, debris, and other contaminants that could potentially cause damage or reduce the engine's efficiency. The engine air filter is typically located in the engine compartment, and it should be inspected and replaced as recommended by the manufacturer, usually every 30,000 to 45,000 miles.
Importance of Replacing Air Filters
Regularly replacing the air filters in a Lexus RX 350 is essential for maintaining the vehicle's performance and longevity. Clogged or dirty air filters can reduce airflow, leading to decreased fuel efficiency, reduced engine power, and increased emissions. By replacing the air filters as recommended, you can help ensure that your Lexus RX 350 continues to run smoothly and efficiently.
Conclusion
In summary, the Lexus RX 350 typically has two air filters: a cabin air filter and an engine air filter. These filters play a crucial role in maintaining the air quality and performance of the vehicle, and they should be replaced periodically as recommended by the manufacturer.
What is the most common problem with Lexus RX 350?
The most common problem with the Lexus RX 350 is a massive oil leak, specifically from the VVT-i oil line, which can lead to rapid oil loss and potential engine failure, especially in older models like the 2010. Other frequent issues include faulty rain sensors, especially in newer models, resulting in wipers that malfunction randomly. Older model years (2007 and 2010) also show a tendency for airbag warning lights and transmission problems, while some 2016 models experienced rough shifting and transmission issues.

Engine and oil leaks
- VVT-i oil line leak: This is a recurring issue, particularly in older models like the 2010, where the oil line can burst, causing significant oil loss and potential engine damage if not addressed immediately.
- Check Engine light: This can be triggered by various engine issues, including problems with the variable valve timing system.
Electrical and sensor problems
- Rain sensor malfunction: Both older and newer models have reported issues with the rain-sensing wipers not functioning correctly or stopping randomly.
- Airbag warning light: This has been reported across several model years, often linked to codes B0111 and B0116 due to issues like faulty sensors or a depleted airbag backup battery.
- Infotainment system issues: Problems like malfunctioning touchscreens, unresponsive climate controls, and other glitches have been reported, particularly in recent years.
Transmission and drivetrain issues
- Rough shifting: Some models, such as the 2016, have been reported to have delayed gear shifts and a lack of smoothness.
- Transmission failure: In the 2016 model year, transmission problems were significant enough to cause concerns about long-term reliability.
Other potential problems
- Spontaneously shattering sunroofs: Though rare, this has been reported in some model years and is a significant safety concern.
- Body integrity issues: Some older models, such as the 2010, have experienced body-related issues like rattling doors.
- Steering mechanism leaks: These can be costly to repair.

How often should I change my Lexus RX350 engine air filter?
Normal Driving Conditions: If you typically drive on paved roads and highways, changing the air filter every 30,000 miles is usually sufficient. Harsh Driving Conditions: If you frequently drive in dusty or polluted areas, or often take short trips, you might need to replace the air filter every 15,000 miles.
Are engine air filters and cabin air filters the same?
No, a cabin air filter and an engine air filter are not the same; they are two separate filters with different functions. The cabin air filter cleans the air that you breathe inside the car's interior, while the engine air filter cleans the air that goes into the engine to keep it running efficiently.

| Feature | Engine Air Filter | Cabin Air Filter |
|---|---|---|
| Purpose | Keeps dirt, dust, and debris out of the engine to ensure optimal performance and fuel efficiency. | Cleans the air for the heating, ventilation, and air conditioning (HVAC) system to provide clean air for the occupants. |
| Location | Under the hood, in the engine bay. | Often located behind the glove compartment, though location can vary. |
| Signs of a clogged filter | Reduced engine performance, decreased fuel efficiency, and poor acceleration. | Reduced airflow from the vents, unpleasant odors inside the car, and increased dust. |
| Maintenance | Often easily accessible for cleaning or replacement. | Can be harder to access, sometimes requiring professional help. |
