Ok, I got the car back from the dealership 5 days ago for being serviced for a leaking radiator and oil leak behind the intake manifold. It sat outside for over a week while there so the battery drained. They supercharged it while it was there and they didn't have problems after. 3 days ago it died (all because of this cold weather in PA), and it wouldn't start after attempting to jump it with 2 separate cars.. so I called AAA. The tow truck showed up, hooked it up and it jumped fine (I guess because the truck had 2 cells hooked to 1 cable). It was hesitant to start the 2 days afterwards so I got a new battery yesterday, everything was fine until tonight. I got in it about an hour ago, and it hesitated to start. It seemed to be idling low/rough and there was a slight hesitation from a stop. 5 minutes later the low coolant light comes on. I'm sitting in a parking garage letting it run and I notice the exhaust smells abnormal, I don't know what it was. So then I leave to drop it off back at the dealership and its not running right.. still hesitating and at this point it feels/sounds weird at low RPMs. By then, I was just hoping to get it to the dealership. What is your take on this?

PS - the only reason I have it serviced at a dealership is because of my warranty.

 

TTT

 

sounds to me like they didn't do their job right ... the abnormal smell could be a bunch of things.. just guessing.. some possibilities of antifreeze leaking on the exaust manifolds/headers.. or any hot part on the motor.. did you see any leaks "still" .. or does everything look clean and sealed up? If it's losing coolant or the coolant is going where it dont belong its definately going to run as you describe after awhile of it being on like that.. especially if its leaking into the wrong places.. ive never had problems or really delt with coolant mixing with anything else in the motor.. only regular leaks out of the motor :/ .. but i know someone else will post and give ya some good answers about it, good luck, and i would definately take it back to them and say WTF ...

try not to run it till you find out exactly what this problem is..

 

I've looked around and I haven't noticed any leaks.. but as of now the car is at the dealership and hopefully they'll have some answers for me tomorrow, because I'm becoming tired of this bs. Hopefully it is just a coolant related problem and nothing more complicated or serious.
