A loud rumble from your car isn’t always something to ignore. While some vehicles are built to have a more aggressive growl, an unexpected change in how your car sounds could be a red flag, especially if it gets louder over time. Many drivers notice their car becoming more vocal and assume it’s just age or road wear, but these sounds can point to issues in your exhaust system. Ignoring the noise might not only lead to further damage but also pose safety risks, decrease fuel efficiency, and even land you with a failed emissions test.
