Rear subframe rusted and broke

I have a 2006 Sanota. The subfram in the back of the car broke wile the car was being driven. It was scarry car was hard to steer and wanted to go all over road lucky there was no accident we managed to pull car to side of road and call AAA have always replaced parts ruteeenly and took my car to the garages. I don't understand how this could happen. car has never been in an accident or anything.

 

That's really interesting

 

I'm sorry to hear about your experience with your 2006 Sonata. The rear subframe failure is indeed a serious issue, and it’s good that you managed to handle the situation without any accidents. There are a few potential reasons for this problem, even if the car has been well-maintained and has not been in an accident.
I recommend having a thorough inspection done by a certified mechanic to understand the exact cause of the failure.
