Drain Plug/ Oil Pan Burrs After 1st Oil Change

Hey guys its my first post on here although I've been reading some of the posts on here. I just took the truck for its 2nd oil change at 9000 miles. The first oil change was free at the dealer 5 months ago and they reported no problems. Today i took it to Car-X a local lube shop and he pulled it in right next to the window. As soon as he got the drian plug off he came in and showed it to me, it was all chewed up near the end. He also said the drain pan had burrs in it also. He grinded the burrs off the drain plug but it still would not go in. He ended up using a 12 mm plug but he suggested that the pan and proper plug be replaced by the dealer. This either happened at the dealer during the first oil change or it was messed up from the factory and the tech never said anything. I called the dealer and he said he would "investigate". I dont know how he is investigating with the truck sitting in my driveway. Should the pan and plug be covered under warranty? Anyone else have similar problems?

I wonder if you have damaged threads in the oil pan oil drain hole, which were caused by a damaged drain plug. The pan is aluminum and the plug is steel, so the pan threads are softer and will get damaged first. The drain plug on my truck was somehow damaged from the factory too, but only a few threads were messed up and it screwed into the pan drain hole just fine. I bought a new magnetic plug from NAPA, as GM no longer sells the plugs with magnets in them. They simply cannot afford such expensive plugs despite at least 5% annual price increase on their trucks.

Well just got back from the dealer and gave them the damaged plug. As far as he could tell it was either from a hyundai or a honda, nothing close to the OEM drain plug. He showed me the differnce and the OEM was atleast an inch longer. No wonder the quick lube guy couldn't thread it in! The dealer then changed the oil and gave me the correct drain plug for free. Dealer has my business from here on out
