So my car is shuddering at lower speeds, and only every now and then. It took me a while to really even acknowledge it because it was rare and I kept just saying it was the road, but the other day it happened and I couldn't just brush it off again. It happens at lower speeds, around 30mph, and when I'm not using much power. Since then I've had it happen twice more, with the most recent one being really dramatic and lasting for a lot longer than before. I went to the service center and drove around with a technician but I couldn't get it to happen again. He said he's never heard of anyone having a problem like this. I was wondering if anyone else seems to have had this happen?
