Hello, i just purchases a mcs 2008, i test drove it for a while and everything seemed fine. I drove it back home for an hour and when i got off the expressway, it started making a grinding sound from engine compartment driver side and it also smelled like coolant. I was able to get home, but now i just bought a car that is parked in front of my house because i dont want to break it more. Any ideas? I also have a video of the sound. Like i said, its coming from the driver side engine. also, the cluster didnt give any alerts for overheating.
