I bought this car with about 28,000kms, and noticed shortly after buying it that it often idled kind of rough. It's not always this way, but it happens often enough that it's annoying. Sometimes when I'm stopped at a light, I can physically feel a vibration throughout the vehicle, and it's so bad that looking in the rear-view mirror, everything is unclear because it's a heaping vibrating mess. It's almost as though the car were a giant cat that was purring, except it's not cute, and you're in it's belly, and it's really annoying. I mentioned it at the dealership a few times over the years but they've never done anything about it, and I'm not sure what I can do to fix it. Possibly a timing belt issue or engine mounts? The thing is, sometimes it's smooth, but other times it's not...even in the warm months.
