The exhaust manifolds bolts are snapping off which is causing leaking and noises (ticking sounds near drivers side) which can be smelled in the cabin and heard in the cabin of vehicle. I been told by other mechanics that this is a severe problem with 5.3 liter and 6.0 liter engines made by GM.. this repair will be in the thousands to fix.

The exhaust manifolds fastners are snapping off which is causing carbon monoxide to fill the cabin area of the vehicle. This hazard jepordizes the health of every person driving or riding as a passenger in the V8 powered vehicles. This is happening to newer models as well. GM is wanting to charge the consumer $1,500-$3,000 to due repairs for defective parts.
