Toyota Avalon 2004 groaning on acceleration Sign In

108,000 miles. 2004 Toyota Avalon XL V6.

This started out of nowhere.

Note: you can hear it best on the 2nd/3rd acceleration attempt.

This sounds bad to me Unimpressed

Any ideas what this could be? thank you.

Sorry, that video is worthless to me. Trying to diagnose a noise over the Internet is near impossible, especially when the recording is made from inside the car.

You can check fluid level if not on the spot find out why.

Noises are tough now a 19ish year old car I suggest paying a pro for minimal time and test drive. If a real trans issue or worn that's it's own trade usually (for me) takes up too much time and valuable space + special tools if a rebuild is in order - unknown right now,

Toyota's are pretty notorious for burning out a small pieces of flex pipe in the exhaust under the engine.

That would sound like the more hopeful better situation, correct? What would you suggest if that be the case.

Fluid levels correct aside from the coolant which I topped off. It was a little low.

Re: Toyota Avalon 2004 groaning on acceleration Sign In

It's probably a side topic but cars don't use up coolant. So why was that low? OR if really cold where you are it just looks lower on a see thru reservoir, all are TMK lots older than this,

(PS!) The quickie oil change places that top off fluids are NOT doing you a favor - WHY IS A FLUID LOW -ANY OF THEM? Not telling you are NOT aware it was a warning of a disaster you could avoid potentially?

Not sure what you meant by the cold but it has been through 2-3 winters where it was as low as 7 F and it did at one point sit without being started for a whole year (i know how stupid that was).

Just to clarify, I did have it inspected for leaks of all kinds. The coolant being a bit low? I have no idea how that would happen.

Every fluid but the coolant was at the correct level. We are not talking about anything significant and I doubt the amount there would have any real affect so I doubt it has to do with that.

Any idea why it was lower than full? i have no idea myself.

This car recovered from a misfire code so at this point im just thinking maybe the damage from that is starting to show or quicken the wear?

I really hope it will just be a muffler problem but... well if its transmission im certainly not rebuilding it.

Ah, they noted this on the oil change and they corrected it by adding fluid. It was almost 50f when this was done so sounds like no.

I wonder how than ?

?? Lower than full?? It's a fluid depends on temperature as it just expands and contracts like all so there's a range.

When off what is expected (anything) the question is why? Find out why if coolant is mixing with ATF for example you are in real trouble.

Don't take me wrong I like you just a warning sign happens out there folks ruin cars over not understanding it,

On record, Marlborough, MA it gets either hot or cold here too, horrid humidity we send hurricanes off shore (luck) none since 1938 where I am.........

And those quickie oil places are not so quickie "8 minute oil change" took exactly 40 minutes Laugh

They cleaned my windows too but they also got oil on my steering wheel, the door, and even on my hood.... smh

Simply have the car looked at to see if the exhaust is leaking. If the flex pipe is indeed rotted out then an exhaust specialty shop can weld in a new one.
