Why does my car make a rattling noise when I accelerate?

Worried because your car makes a rattling noise when accelerating? Here are some common causes for that
1. Broken Heat Shield on your exhaust
Heat shields are metal guards that surround parts of the exhaust system, keeping your car safe from the heat it puts out.
2. Worn or damaged motor mounts
The average car engine weighs about 300 lbs and the engine mounts are what hold it securely in place. They’re made of rubber and metal and if they’re damaged, there’s nothing to stop it from moving around.
3. Valve issues with your motor
Intake and exhaust valves could be are stuck or worn
4. Transmission
There is a lot happening in your transmission, old, worn or low fluid can damage your transmission and make a weird noise when driving
