Default Noisy startup 2011 Prius

Hello,

We just purchased a 2011 Prius this past July and we love it. However, this past weekend we were visiting relatives about 150 miles from home and when I went to start it the next morning (temperature approx 35 degrees if that has any bearing) it made such a "clanking" noise it could be heard inside the house by our daughter. I would have to describe the noise as similar to a regular 6 cylinder engine with 2 spark plug wires detached. The noise was "acute" to say the least so I turned it off then re-started it and the same thing happened for about 5 seconds then it went to the normal quiet start-up and all has been fine ever since.

When we got back home, I took it into our Toyota dealer who performed every test they knew including "internal code diagnostics" to see if there was any clues but they found nothing that would tell them what this could have been.

So now I have this inner-feeling of disaster awaiting and we're about to take a long trip some of which is in desolate Nevada country. So, if anyone out there has experienced anything similar to this description, I would certainly appreciate a reply to what their experience may have been and what they did to correct it.

Thank you,

jnulr

Hi, jnuir,

You're not alone in hearing a very noisy start-up of the Gen3 Prius (2010 & 2011), especially with a "cold" start. Do a search & you may find some of the threads. There was even some scuttle-butt about Toyota being close to issuing a TSB to fix the problem & some months ago a Toyota service technician (that is a member here) shared what he thought the problem could be because another Toyota engine in another model car was exhibiting the same noisy start-ups. I don't have the time right now to point you towards one of them with a link, but somebody else here may be able to provide you with a link right away. I still may be able to as well, but later.

Thank you Ken. I appreciate your response. At least now I've found someone who's experienced the same problem. I'll try the search.

Thanks again,

Hey, jnuir,

Did you have any luck with your searches yet? You may want to do some searches over at PriusChat. That may be where some more threads are. If you find a thread there, look at the similar threads they list after the last post & you may find what you're looking for. I know somebody recorded the sound & put it on YouTube too. As you will see by the time of my post, it's very late again, so I still don't have the time to point you to specific links. By the way, I don't have a 3G Prius, so I myself haven't experienced the noisy start-up. I was just saying by the number of complaints I've read about, that you're not the only one to experience the loud rattling start-up.

I have a 2011 and just yesterday experienced the same thing. I backed the car out of the garage and turned off the engine. On restarting everything was normal. Please post any explanations/resolutions. CCCollins

Something like that. Maybe more of clank or knock. It was cold, high 20's-low 30's, but the car was garaged.

Thanks very much for all your responses. I think "firepa63" might have the avenue to a warranty solution for this problem. I'll let you know how my dealer responds after I get back home (where I bought it) in May. I printed this out and will give it to them.

Thanks again for all your input everyone.

This is a great website for Prius owners that's for sure.
