Good morning all,
I've a 2006 CTS with 37k on it. While sitting in park, or while at red lights, I am noticing a shudder every 15-20 seconds. Some strong enough that makes me look at dash readouts to ensure the car did not die. I have noticed that it does not seem to have as much power as I expected, especially from the line. However, being that I've only had the car for 3 months and my previous vehicle was a V8 Tundra, I just assumed that it was because of the smaller engine. I still think it should have more power, though. :-/
On top of that...I have to have about $1000 in work done today due to a locked up caliper on the passenger side causing a shimmy. Ah, FML!
