To reset the Lexus RX 350 climate control, you can either reboot the infotainment system by holding the radio/multimedia knob for several seconds while the car is in park and started, or disconnect the negative battery terminal for 10-15 minutes and then reconnect it. If these steps don't work, a more complex issue like a faulty blend door actuator, control module, or sensor may be the cause and requires further diagnosis, such as a self-diagnosis test by holding the AUTO button and Recirculation button for 5 seconds while the ignition is on. 
Method 1: Reboot the multimedia system 

1. Ensure the vehicle is in park and started. 
2. Press and hold the knob for the radio/multimedia system for several seconds until the infotainment screen reboots.

Method 2: Disconnect the battery 

1. Disconnect the negative terminal of the car battery.
2. Wait for about 10-15 minutes to allow the system to fully discharge.
3. Reconnect the battery terminal.
4. Start the car and check if the climate control is reset. 

Method 3: Perform a self-diagnosis (if the problem persists) 

1. Press and hold the AUTO button and the Recirculation button at the same time. 
2. Turn the ignition to the "ON" position (without starting the engine) and then release the buttons. 
3. Observe the display for flashing numbers, which are error codes. 
4. Use these codes to identify the issue, which may require professional attention for components like the blend door actuator, control module, or sensors. 

What is the most common problem with Lexus RX350?

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.
