When I started the engine this morning my Toyota Prius plus

Customer Question

Hi, when I started the engine this morning my Toyota Prius plus excel made a roaring noise, I don't know what the issue is. When I went out and looked around and under I saw something suspicious, there is a 5cm long spring and bolt on the floor and something like a cover is hanging and there looks like a rubber tube hanging there as well
JA: Have you checked the battery, particularly the terminal connections? Are they corroded?
Customer: It is a relatively new car a Toyota Prius plus excel of 69 registration with just 15000 miles, I bought it only last week
JA: What year is your Prius?
Customer: 2019, I'm here in London, UK
JA: Are you fixing your Prius yourself? What have you tried so far?
Customer: No I called the dealer where I bought it from they told me to call Toyota because it is still in warranty
JA: Anything else you want the Mechanic to know before I connect you?

If your catalytic converter has been will know straight away as you will obviously hear the engine running alot louder then it normally a large open hole in your exhaust for example... but you will also be able to know too if you see bits of metal of bolts laying around under neath..although because those theives use Reciprocating usually a clean cut at either side of the converter..unless you can get it jacked up to have look underneath or know of local garage you can take it too and get it ona ramp.then you know either way whats happened..
