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.
Addressing the non-functioning cruise control in a 2018 Lexus GX460 is more urgent than it may initially seem. A malfunctioning cruise control system can pose significant safety hazards, as it may fail to disengage when needed, potentially leading to loss of vehicle control in critical situations. This risk is compounded during long drives, where the convenience of cruise control greatly enhances comfort and reduces fatigue. Ignoring this issue not only compromises your driving experience but could also lead to more severe mechanical problems down the line, such as damage to the throttle control system or other related components. Common culprits behind cruise control failures include blown fuses and defective brake pedal switches, which are relatively easy to diagnose and fix. Therefore, it is advisable to promptly investigate any cruise control issues to ensure both your safety and the optimal performance of your vehicle. Taking action sooner rather than later can prevent minor inconveniences from escalating into major repairs, making it a wise decision for any DIY enthusiast.
