A common issue causing the failure of the start-stop system in a 2017 Toyota Highlander is insufficient voltage in the vehicle. When the car detects a problem with either the alternator or the battery, it will disable the start-stop feature to prevent potential startup issues if the car is turned off. The purpose of the start-stop system is to save fuel in your SUV by shutting off the engine automatically when you stop in traffic to avoid unnecessary fuel consumption. However, if you remain stationary for an extended period, the system will restart the vehicle to prevent excessive battery drain from electrical accessories.
