1. Dashboard Warning Lights You Should Never Ignore
Your car has a way to tell you something is wrong. That is with the dashboard warning lights. These lights on your dashboard are like a message from your car; they tell you when something is not working right. Your car uses these dashboard warning lights to alert you to problems. Some of these dashboard warning lights are for issues but some dashboard warning lights mean you need to do something about it right now.

2. Unusual Engine Noises That Signal Serious Problems
When you are driving a car the car will make some noise. This is totally normal. Sometimes a car will make a strange sound. This sound is not normal for the car. If you hear this sound it probably means that something is wrong with the car. If you do not do anything about the sound you might have to pay a lot of money to fix the car. The car will need repairs that can be expensive.
Some common noises and their possible causes include:
- Knocking sounds: May indicate engine wear or low engine oil.
