The appearance of the check engine light in your 2018 Chevy Silverado truck can indicate a variety of potential problems. Some issues are more common than others, so it's important to address them. One common cause is deteriorating spark plugs, which should be replaced regularly according to your maintenance schedule. Additionally, low oil levels could trigger the check engine light, so it's essential to monitor both the oil life light and the engine light for any indications of low oil affecting your engine.

I drive a 2018 Silverado 1500 pickup truck. Unlike other years, this one doesn't use a traditional gas cap; it has a sealing flap instead. If dirt accumulates around the flap, it can cause air to get in, messing up the sensor and triggering the check engine light. To fix this, clean the flap and the area around the opening so the flap seals correctly. After that, have your mechanic reset the code, and you shouldn't encounter any more problems if you keep the flap clean on a regular basis.

If the "check engine light" turns on in your 2018 Chevy Silverado, it could mean that either your gas cap is loose or there may be a more significant problem such as a malfunctioning o2 sensor, a bigger emissions leak, or issues with the catalytic converter in your vehicle.

I have a question about my husband's 2018 Chevy Silverado, as the engine light is on. When we took it to the dealership, they were unable to determine the issue. They attempted to open a front flap related to airflow regulation in the engine, but we're not certain about the technical term used. Also, whenever we drive at speeds between 50km to 60km, the vehicle shakes and vibrates excessively. Despite the dealership's efforts to experience the problem firsthand, they still haven't identified the root cause. Does anyone have suggestions on what steps we can take regarding our vehicle? The situation is unsettling every time we drive. Thank you for any advice.
