Flex Pipe Failure

[SonicBoy24]

Recently had to replace the exhaust flex pipe on my 1.8 due to it rusting and separating itself.
(didn't put this in 1.8 specific because 1.4 could have this issue too I suppose)

Pictures show the new on the left, old on the right obviously
(edit: SOF flipped the pictures, new on bottom now).
You should be able to spot the issue.

Haven't seen or heard of anyone else having this issue, but it happened with approximately 33k miles


The exhaust sounded, in my opinion, great with the leak, although it was hurting gas mileage as it was before the o2 sensor.

Also took a video of the car with no exhaust past the stock manifolds.

Didn't rev it!

Any warranty coverage on that part???

 

[SonicBoy24]

I wanted to rev it, but it was running extremely rich with no 02 sensor so even with just that short runtime the garage was smelling terrible

No warranty because I bought my car on halloween of 2011, so the 3 years as been up for a while

 

[Natesriv]

yeah, guess that doesn't fall under powertrain

But it should fall under emission components. I'm really surprised that's not covered.

I didn't even bother to ask the dealership to be honest

Emission Equipment is like 8 years isn't it?

Is the corrosion/rust likely due to road salt. If so, there is likely to be a lot of these failures in the snow belt regions.

That leak is well after the primary O2 sensor, but before the catalyst monitor sensor.

the cat should be covered ... but I don't see the rest of the exhaust system being covered ... but should be worth looking into

Not covered, replaced the same components personally on my Father In Law's HHR as well as my sister's HHR, rusted in the same exact place. Neither was covered under warranty on those reguardless of mileage or age.

Just had this happen to me. 96k miles. Off to the muffler shop i go :-(

I had this happen to me this past weekend. Have the new pipe coming. But it doesn't come with the needed gaskets and hardware. I have the gaskets but I can't find the hardware anywhere. Does anyone know what size bolt and nut these take?

This happened also last year on daughters 2014 Sonic LT w/1.8L engine.

About 82,000 miles at the time. We had a flex pipe repair section welded into place for about $92.
