Oil pan plug threads apparently stripped

[RMcG]

I almost always get my oil changed at walmart. I went yesterday and had the oil changed and the manager told me when they tried to tighten the drain plug it just spins. They said they checked it and it is not leaking, even when the oil system is pressurized. They recommend "Panthread service before next oil change." I am personally worried it's going to leak long before the next oil change or even just let go and essentially run out.

We looked back at the previous oil change (done by Walmart 5K miles ago). There were no comments about the drain plug being faulty. In fact the comments appear to say they torqued the plug to 28 foot pounds, which I think is what they say they usually do.

QUESTIONS: Do you guys recommend putting new threads in by tapping the plug hole?

Or should I have a new pan installed?

How much will these kind of jobs cost?

Do you think I have any hope of getting Walmart to cover the cost of these jobs?

Thanks,

R.
