Some Acura TL owners report experiencing difficulties with their cruise control not engaging, even after multiple button presses. This issue may stem from a faulty cruise control switch on the steering wheel, which can malfunction and prevent proper engagement. Additionally, problems with the control module, sensors, or switches are common culprits behind cruise control failures. Throttle sensor failures can also contribute to these malfunctions. Some owners find that a bad clock spring, located behind the steering wheel, affects the functionality of the cruise control buttons. Furthermore, issues related to the cruise system components, such as the brake switch, cruise servo, or wiring, may also be involved. To diagnose the problem, some owners recommend using a scan tool to identify any fault codes that could be disabling the cruise control system. It is also advisable to check for blown fuses related to the cruise control system, as these can disrupt power supply to essential components. If the cruise control remains unresponsive, it is important to have the necessary components checked or replaced to effectively resolve the issue.
