Trailblazer Manifold

Hey guys, do any of you technicians, service advisors or Trailblazer owners know of any sort of history with the exhaust manifolds ( straight 6 ) cracking on this vehicle? It does not matter on the year, just have you seen this being a problem?

Thanks in advance.

I have a 05 with the 6 cylinder, with 55,000 miles on it and haven’t had any problems with the exhaust manifold.

I checked for recalls and TSBs and there aren’t any for a cracked manifold.

thank you…anybody else?
