Well, I'm about to roll 30k on my '14 LTZ and I'm finally having my first issues. First, a little back story. My '14 came with the 2 years free oil changes/tire rotations. I had them done every 5k. I should also say I've had bad luck with my local dealership, so much so that I didn't buy the car from them. When I owned my previous car (02 Intrigue), I developed a relationship with the local Buick/GMC/Cadillac dealer. I had my first 2 oil changes done there. When I went in for my 3rd oil change, I had received the airbag recall letter. When I took it in, I quickly got a call that they were unable to perform the work because GM wouldn't authorize the recall work and I had to take it to a chevy dealer. So, I made an appointment reluctantly with my local dealer. Much to my surprise, I had zero issues. For my 4th oil change, I took it back there again.
At 25k, I went to do my first oil change. Then I discovered why I won't do business with my local dealer. The oil drain plug (which clearly says 14 Nm right on it!!!!) was torqued so friggin tight I rounded it off trying to get it off. Ended up having to run to the hardware store to get a bolt extractor set and to the dealer to buy a new drain plug. I wanted to complain, but decided it was easier to just let it go. I also noticed there was oil all over the pan. I was hopeful it was due to them over-tightening the drain plug and wiped everything down.
Last week, I put my snow tires on and there is even more oil on the pan as well oil all over the other side (under the driver). Finally today, I noticed I'm low on coolant. Barely any in the tank.
Since I'm not quite to 30k yet, I've still got bumper to bumper left. My dilemma is whether to go back to my local dealer and complain about the drain plug and try to blame anything on that, or just to cut my losses and choose a new dealer closer to work. There are 2 within a reasonable distance..... I'm thinking I'll find a better dealer.
Any ideas where my oil leak is most likely coming from? I don't see/feel any oil on the top side of the engine (throttle body, etc). I did feel around a bit. Also, what's the most likely cause of low coolant? I should also note that I don't smell antifreeze or see any smoke in the exhaust. Also, I'm not noticeably losing oil on the dipstick. Could they be related?
