And the 2.7% of gen 3 engines effected by severe piston slap was quoted from the herald sun some time ago, there was a section on it with the title reading 'Heart Problems' or something from memory.

Whilst it is tempting to marginalise the problem by looking at relative figures and percentages, GM in the US alone is talking about 800,000 cars, trucks and SUVs.

No wonder they didnt want to fix the things.

yes i have heard that their toronto factory is to blame for a lot of the problems...not sure on the validity of this rumour, i dunno if there is even a toronto factory!
