"sorry if I'm not using this complaint system correctly" lower intake manifold gaskets need replacement on 2003 Pontiac Grand Prix with only 33.4K miles on it. Bought car new. $1100+ to have fixed. Seems to be a big problem all over America and with Canadian lawsuit. Dealership did not offer to fix.
