Has anyone heard anything about the 3.6tl in the 08 GXP i have had my motor lock up twice now an both times i was told it was a GM mistake. First time my #2 rod an crank broke now it has happened again. But this time GM was so nice to send me a new motor!
No, I haven't. I've had no problems with mine and here's hoping I don't.

Yeah maby i was one on the lucky ones who ended up with a messed up motor some guy wason the job
My 07 has been fine. I know Albert, steelgtp has had so many problems with his, that he had to sue GM to get it fixed. He has now spun a rod bearing so he's have the shop fix it and trading it in for something else.

My first motor rebuild cost 8k with labor an parts. and this one is around the same. So im gonna try to get the lemon law because its three issues for the same thing or over 15k. which i will be over!
Albert, that's the spirit. Go after them. Nate, I just caught up with Steel's tragic tale.

I know, sad indeed. I'm hoping to nab his ported manifolds, depending on how much money it costs.Originally Posted by standfast

I just got a call from GM because my car is over 40k miles they want to give me a 75% refund on my car. Because Pontiac will be hard to find parts for in the future. It helps When your dad work for GM. NEW CAR! im thinking Subaru STI!
For the most part the 3.6L is a good GM engine. My GF even has it in her Torrent GXP and puts 12K a year on it. Engine if anything the 3.9L/3900 is an issue, that engine a few members including myself has had head gasket leaks and theres a GM bulliton on that engine.
