Identify the Problem

• Start by determining the specific driver assistance feature that is malfunctioning. Common features in the 2018 Chevrolet Bolt EV include lane keep assist, forward collision alert, and automatic emergency braking.
• Note any error messages or warning lights on your dashboard that might provide clues about the issue.
• Keep a record of when the issues occur, as this can help in diagnosing intermittent problems.

Check System Settings

• Verify that the driver assistance features are enabled in the vehicle’s settings. This can usually be done via the infotainment system menu.
• Ensure that you adjust the settings to your preference, as some features offer sensitivity adjustments, like the distance for forward collision alerts.

Inspect Sensors and Cameras

• Clean all sensors and cameras located on the front and rear of the vehicle. Dust, dirt, or debris can obstruct their view, leading to malfunction.
• Ensure that no modifications, such as bumper stickers or aftermarket accessories, are obstructing any sensors or cameras.

Update Software

• Check if there are any software updates available for your vehicle. This may require visiting a Chevrolet dealership, as updates for driver assistance systems may need to be installed by professionals.
• Consult the owner’s manual or Chevrolet’s official website to determine how to check for software updates specific to the Bolt EV model.

Review the Owner's Manual

• Consult the Chevrolet Bolt EV owner’s manual for detailed information about your car's driver assistance features.
• The manual can provide troubleshooting tips and may offer insight into specific error codes displayed on the dashboard.

Perform a System Reset

• Try resetting the infotainment and driver assistance systems. This can often be done by disconnecting the battery temporarily or using any available reset option in the settings menu.
• Keep in mind that a system reset might require you to re-enter certain settings or preferences after the process.

Professional Inspection

• If the above steps do not resolve the issue, it's recommended to take your vehicle to a certified Chevrolet dealer or a trusted mechanic who is familiar with the Bolt EV.
• Issues with the driver assistance systems can be complex, and a professional inspection might be necessary to address technical malfunctions or hardware failures.
