2017 Chevrolet Traverse - Cat issues

just sent my 2017 traverse to the shop to replace the catalytic converter. it only has 37,000 miles on it. they also said the power steering hose is leaking and causing my o2 sensor to go out and will ruin catalytic converter if not fixed. My traverse also has the traction control issue as the person above mentioned.

So? It’s being done under the warranty.
But how does power steering fluid get into the exhaust system to affect the catalytic converter?

I don’t think this car has a power steering hose. It has electric assist steering.

That cat is still under warranty.

The catalytic converter(s) in your vehicle are warranted for 8 years/80,000 miles.
