I have a 2013 Toyota Hybrid [Prius](/topics-prius/). When i accelerate I hear rattling loud noise and it sometimes does it when I start the car too. Its louder when I start the car Mechanic's Assistant: Where exactly do you think the noise is coming from? And how long has this been going on? I believe on the right front passenger side underneath For about 2 months Mechanic's Assistant: Are you fixing your Prius yourself? What have you tried so far? No not yet Nothing Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? No other than i am aware that the coolant level seems to be low

There are a few more things that can give you also a noise but with a running rough situation ,don't know if your engine runs good when the noise is present . If it does not run good ,maybe its a good time to replace the [spark plugs](/topics-spark-plug-toyota/) and also check the EGR performance ,to do the EGR ,you will need a Toyota capable scanner. Let me know if you need any further questions when your husband get there. Thank you.

Its runs good.. might be alittle sluggish..I will mention to my husband, thanks
