The 2018 Chevrolet Silverado boasts an impressive array of features that make it one of the most popular trucks on the market. Among these is the convenience of remote start, designed to allow you to start your vehicle from a distance, preconditioning the cabin for comfort regardless of the weather. However, like any technical system, there may be times when your Silverado’s remote start function doesn’t work as intended. This comprehensive guide aims to dive into the common issues with remote start systems, how to troubleshoot them, and potential solutions to get your vehicle back up and running.
Understanding the Remote Start System
The remote start feature in your 2018 Silverado is part of the vehicle’s keyless entry system, providing users with the ability to start the engine from a distance. To understand why this feature may fail, it is helpful to know how it works:
- Key Fob Activation: The remote start process begins when you press the ‘start’ button on your key fob twice within a few seconds.
