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.
When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.
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.
When faced with a non-functioning cruise control in your 2017 Lexus GS350, it's important to approach the diagnosis methodically, starting with the simplest solutions. Begin by checking the cruise control fuse in the fuse box, as a blown fuse can easily disrupt the system. Next, inspect the cruise control buttons on the steering wheel for any signs of damage or malfunction, as these controls are crucial for operation. It's also essential to verify that the vehicle's speed sensor is functioning properly, since cruise control relies on accurate speed readings to maintain set speeds. Additionally, examine the brake pedal switch, which should disengage the cruise control when pressed; a faulty switch can prevent the system from engaging. Don't overlook the throttle cable, as any damage or sticking can hinder the cruise control's performance. Finally, using a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues. By following these steps, you can effectively troubleshoot and potentially resolve the cruise control problem in your Lexus GS350.
When troubleshooting the cruise control system in a 2017 Lexus GS350, it's essential to be aware of the common problems that may lead to its malfunction. A frequent issue is a faulty speed sensor, which can disrupt the system's ability to accurately gauge the vehicle's speed, preventing it from engaging or maintaining the desired speed. Additionally, problems with the brake light switch can interfere with the cruise control's operation, as this switch is designed to disengage the system when the brakes are applied. Another potential culprit is a malfunctioning throttle actuator, which is responsible for adjusting the engine's throttle in response to cruise control settings; if it fails, the system may struggle to maintain speed. Electrical issues, such as wiring faults or blown fuses, can also cause the cruise control to stop working altogether. Lastly, a failure in the cruise control module itself can prevent the system from functioning properly. For those looking to DIY, it's crucial to systematically check these components to identify and resolve the issue effectively.
When assessing the urgency of repairing the non-functioning cruise control in a 2017 Lexus GS350, it is crucial to recognize the potential safety risks associated with this malfunction. A malfunctioning cruise control system can lead to unpredictable vehicle behavior, particularly during long drives or in heavy traffic, where maintaining a consistent speed is essential for safe driving. Additionally, the absence of this feature can significantly detract from driving comfort, especially on extended journeys where fatigue can set in. Beyond immediate safety and comfort concerns, neglecting to address this issue can also affect the vehicle's resale value. Prospective buyers often view unresolved mechanical problems as red flags, which can lead to lower offers or deter them altogether. Therefore, while the urgency may vary based on individual driving habits, it is advisable to prioritize the repair of the cruise control system to ensure a safe, comfortable, and valuable driving experience.
