It can always be a little worrisome when your car starts making strange noises. There might be several causes for the rattling noises you’re hearing, so the best way to try and pinpoint the problem is to listen to where the noise is coming from.
Here are some common culprits of rattling noises and where the sound should be coming from:
  • Loose exhaust system: you’ll hear rattling noises toward the back of your vehicle
  • Failing catalytic converter: rattling will come from under the car
  • Defective heat shield: noises will be coming from under the car
  • Loose brake components: depending on which components are loose, you might hear noises toward the front or rear of the vehicle
  • Low oil pressure: rattling will come from the engine
Rattling noises almost always signify an underlying problem, so it’s best to take your vehicle to a mechanic and have it looked over.
