Harmonic Balancer replaced twice in a year. Worry? I have a 2007 Cadillac CTS-V (LS2) that I've almost had for a year now
Bought from a Chevy dealer and did pay for a third party warranty because it's my only car and did not know a whole lot about wrenching at the time. Early on I experienced a squeaking noise on cold starts because I bought in the winter it was pronounced. Would go away after 5 minutes of driving and would have to be dead cold to start again. The Dealership said it was the harmonic balancer so my warranty paid for the repair but I had to pay for the new belts in May. Now that winter came along the squeak was back! And seemed worse than before. I turned it in and they said it was the balancer again. The positive thing was the part had a GM warranty so it was $0 cost this time. However they took 2 days to work on it and said GM's part warranty doesn't provide a loaner car which was extremely inconvenient, but it did solve the issue and it's dead silent on 30 degree mornings. Anyway my main concern was if there might be something more concerning possibly going on? What would happen if I just let this inconvenient squeak continue?

Piggy backing off of what farmington said I found out about balancer issues on Vettes from that time frame when I was researching balancers myself for my truck but I'm sure the issues were happening to CTS-V's as well;
Like farmington said a few switched to a ATI or IW balancer to "solve" the problem.

I wouldn't hesitate to put a Fluidampr on my car. I just happened to catch a deal on a blem ATI on Ebay for $250. For some reason I don't think the LS6 variants had the issue. Mine had 170k on it when replaced and it wasn't bad. I was just chasing vibration issues which it didn't solve.
