On June 15th 2017 I took my 2005 Dakota in to have the oil changed With a 16-point inspection Which would be An oil change Lube filter and inspection.Noticed the next week which would be the 22nd of June Thursday There was a fluid leak under my truck Try to take it in Thursday With no luck no one could look at it.I dropped it off At noon Friday the 23rdTo find out what the fluid leaking was.Found out Friday at 3 p.m. the leaking fluid was oil From the drain plug in oil pan.Straight up! somebody didn't tighten the drain plugAnd that cost me $61.59 More than the oil change itself .I would like someone to explain to me how an oil drain plug can malfunction.I am hoping to meet with the service manager This week coming Maybe He or she can Help me out with this. Thanks
