Looks like GM wants to save a few pennies and shaft the customer.

The part I cannot understand is the fact that the L36 has been in production for almost 10 years now, the upper intake manifold is VERY evident and very little has been done about it.

Baffling.

I always figured when you have a problem you do your best to fix it. Maybe I missed that memo

it happens out of warranty, so they would only lose money by recalling. I thought the L32 fixes it?

Remember the Upper intake was changed in 99 production, so all 00+ engines should be fine INTAKE wise. The gaskets may have other problems, that only show up since they aren't being replaced every 80k miles.

When I had my upper intake replaced, they tried telling me the same thing, replace the gasket only. I told them to take a closer look at the intake, then they saw what I was talking about.

Is there anybody with a 2000 or above bonneville that has had their intake fail on them? I'm hoping not, since my brother just bought a 2000 SLE.
