Does the Lexus RX have adaptive cruise control?
Yes, the Lexus RX does come equipped with adaptive cruise control as a standard feature. Adaptive cruise control is an advanced driver assistance system that automatically adjusts the vehicle's speed to maintain a safe following distance from the car in front of it.
What is Adaptive Cruise Control?
Adaptive cruise control (ACC) is an automotive technology that automatically adjusts a vehicle's speed to maintain a safe following distance from the car in front of it. Unlike traditional cruise control, which maintains a constant speed set by the driver, ACC uses sensors to detect the distance and relative speed of the vehicle ahead and adjusts the throttle and brakes accordingly to maintain the desired following distance.
How Does Adaptive Cruise Control Work in the Lexus RX?
The Lexus RX's adaptive cruise control system uses a radar sensor mounted on the front of the vehicle to detect the distance and speed of the car ahead. When the system detects a vehicle in front, it will automatically adjust the RX's speed to maintain a safe following distance set by the driver. The system can bring the vehicle to a complete stop if necessary and will resume driving once traffic starts moving again.
Key Features of Lexus RX Adaptive Cruise Control
- Radar-Based Sensing: The RX's ACC system uses a front-facing radar sensor to detect the distance and speed of the vehicle ahead.
- Adjustable Following Distance: Drivers can set the desired following distance from the car in front, choosing from multiple distance settings.
- Automatic Braking and Acceleration: The system will automatically apply the brakes or adjust the throttle to maintain the set following distance.
- Stop-and-Go Capability: The ACC system can bring the RX to a complete stop in traffic and resume driving once traffic starts moving again.
The Lexus RX's adaptive cruise control system is designed to provide a more relaxed and safer driving experience, especially on long highway trips or in stop-and-go traffic conditions.
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.

How do I know if I have adaptive cruise control?
You can tell if you have adaptive cruise control by checking for a specific icon on your dashboard, looking for dedicated buttons on your steering wheel (like an "ADAPTIVE" button or a distance control button), or by inspecting the front of your car for a radar sensor behind the grille. If your car can automatically adjust its speed to match the vehicle in front of it, it has adaptive cruise control.

Check your dashboard
- Look for a specific icon when you turn your car on. It might look like a speedometer with a car in front of it or a car with lines trailing behind it.
- When you activate the system, the icon may change color. For example, in some vehicles, a white icon means it's on but not active, while a green icon means the system is actively following a vehicle.
Examine your steering wheel
- Look for a set of buttons on your steering wheel. Adaptive cruise control systems often have a button to turn the system on or off, and a way to set your desired following distance, according to Reddit and Ranger5G.com users.
- Some vehicles may have a separate "cancel" button or may require you to press and hold the cruise button to switch between adaptive and regular cruise control, notes GMC and Reddit users.
- In some newer cars, the cruise control system may automatically engage and you don't need a separate "on" button.

Look for a sensor on your car
- Check the front of your car, usually behind the grille or bumper. Adaptive cruise control systems use a radar sensor to detect other vehicles, so you may see a small square panel located behind the license plate or grille, says Bimmerpost.

Test the feature
- The most definitive way to know is to test the feature. If you are driving on the highway and engage your cruise control, it will slow down to match the speed of the vehicle in front of you. You can then deactivate it by pressing the "cancel" button or tapping the brake.
