The most common reasons a 2016 Acura RDX cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.

Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
Control Module: A faulty control module can result in erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent acceleration and poor engine response.

How much does it cost to fix a 2016 Acura RDX cruise control isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.

What are the steps to diagnose the cruise control issue in a 2016 Acura RDX?

To effectively diagnose a cruise control issue in your 2016 Acura RDX, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the control module, sensor, and throttle actuation, as these are common culprits for cruise control malfunctions. Next, check for any blown fuses in the fuse box, particularly those related to the cruise control system, since a blown fuse can disrupt power to critical components. After ensuring the fuses are intact, assess the signals entering the controller to confirm they are functioning correctly. Additionally, inspect the actuator to verify its operational status. If these steps do not resolve the issue, consider replacing the controller as a last resort. By following this structured diagnostic approach, you can efficiently identify and address the root cause of the cruise control problem in your Acura RDX.

How urgent is it to address the malfunctioning cruise control in my 2016 Acura RDX?

When it comes to your 2016 Acura RDX, addressing a malfunctioning cruise control system should not be overlooked, even if it may not seem as urgent as other mechanical issues. While the immediate safety risks may not be as pronounced as those associated with brake or engine failures, a faulty cruise control can still significantly impact your driving experience. It can lead to difficulties in maintaining a consistent speed, which is particularly frustrating during long highway drives. Moreover, ignoring this issue could exacerbate underlying problems, potentially leading to more extensive and costly repairs in the future. Therefore, it is advisable to prioritize fixing your cruise control system to ensure a smoother, safer, and more enjoyable driving experience. Taking action sooner rather than later can help you avoid unnecessary discomfort and maintain the reliability of your vehicle.

Acura RDX transmission hesitation during shifting after fluid change and software update

Some Acura RDX owners report experiencing transmission hesitation during shifting after a fluid change and software update. This issue may stem from the recent software update, which could have addressed previous shifting problems but may also introduce new ones. Additionally, drivers often face confusion and concern following a transmission fluid change, as symptoms such as leaking fluid, difficulty shifting gears, and harsh shifting may arise. To mitigate these issues, owners are advised to check the transmission fluid level and ensure it is within the recommended range, using only OEM Acura/Honda transmission fluid for optimal performance. Some owners also consider performing a transmission software update to resolve control issues affecting shifting. Furthermore, if the transmission control module detects a fault, the vehicle may enter limp mode, restricting shifting capabilities. Lastly, premature fluid wear may lead to torque converter issues, exacerbating shifting problems. It is crucial for owners to address these factors promptly to maintain their vehicle's performance.

Mitsubishi Diamante cruise control malfunction after drive line obstruction removal

Some Mitsubishi Diamante owners report experiencing cruise control malfunctions after removing a drive line obstruction, often linked to issues with the control module, sensor, or switch. These problems may stem from failed components that prevent the cruise control system from engaging or holding speed, despite power being available to the dash and fuse. Additionally, throttle actuation issues, such as a faulty throttle position sensor, can lead to the engine's computer overcompensating with fuel, which may result in black exhaust from the tailpipe. Owners are advised to thoroughly troubleshoot the cruise control system and inspect key components like the control module, sensor, and throttle to identify any damage or malfunction caused during the obstruction removal process.
