Ignoring the check engine light is considered neglect, and it can void your vehicle's warranty. This is because the check engine light is a warning that there is a problem with your vehicle that needs to be addressed. By ignoring the light, you are putting your vehicle at risk of further damage, which may not be covered by your warranty.

For example, if your check engine light is on and you continue to drive your vehicle, you may damage the catalytic converter. The catalytic converter is a vital part of the emissions system, and it can be very expensive to replace. If the catalytic converter is damaged due to neglect, your warranty may not cover the cost of replacement.

Ignoring the check engine light can have serious consequences, including voiding your vehicle's warranty. By understanding the connection between the check engine light and your warranty, you can make informed decisions about the maintenance and repair of your vehicle.

Cost

This is because the check engine light is a warning that there is a problem with your vehicle that needs to be addressed. By ignoring the light, you are putting your vehicle at risk of further damage, which can be more costly to repair.

Delayed repairs: One of the most common consequences of ignoring the check engine light is delayed repairs. This can happen for a variety of reasons. For example, you may not have the time or money to get the repairs done right away. Or, you may simply not realize that the check engine light is on, or what it means.
