You might have exhaust coming in if:
• Your exhaust system sounds strange or different.
• Your vehicle gets rusty underneath.
• Your vehicle was damaged in a collision.
• Your vehicle was damaged when driving over high points on the road or over road debris.
• Repairs were not done correctly.
• Your vehicle or exhaust system has been modified improperly.
If you ever suspect exhaust is coming into your vehicle:
• Drive it only with all the windows down to blow out any CO; and
• Have your vehicle fixed immediately.
