This is why you can't trust anyone to work on your car.

As they say, the first thing to wear out on a new car is the drain plug.

This is why.

I have a 2012 Cruze and the dealer did a warranty repair on my car for an oil leak (valve cover)...well they nearly rounded off the drain plug in ONE oil change, where I had done it at least 10 times before. Thankfully it still came out. Just had to buy a new drain plug.
