Hello everybody, I mostly lurk around here but now have a question.

A little over a week ago, I took my '05 Kia Optima in for 60k miles service. Lots of things were done to it including changing the timing belt and a tuneup. Immediately after I got it back I noticed abnormal vibration esp in the 3k rpm range. I did some research on this and found that this car is normally "buzzy" esp in the 3k rpm range so I ignored it for a week. Then I started noticing yet _more_ vibration accompanied by new and exciting rattles and buzzes. I dropped it off at the shop to have it looked at and I got a call later in the day to learn that it was either the timing belt off by a tooth or a balance shaft issue.

Now, I'm no automotive savant - I just know the fundamentals, but it seems awfully suspicious that after a tuneup and new timing belt the engine runs like an adult battery operated toy. The mirrors are blurry, that's how much it vibrates. What recourse do I have if I want to, say, dispute the charges. They've had it for 2 days now so I can only imagine the lovely bill I'm going to get. It seems very much like they either screwed something up or just plain sabotaged it and I don't feel like paying for their mistake.

So what would you do? I've searched to see what other people do if their car is messed up straight out of the shop but found nothing. Please let me hear any advice you have.

Many thanks,
Rob
