Engine failed on highway in a different state, was able to drive home but barely made it. 2 newborns, 2 toddlers, and 2 adults were all in the vehicle at the time the engine started squealing. No warning signs. Dealer dropped oil filter and it was full of metal. Official diagnosis was main crank thrust bearing failure. Rebuilt engine was installed under powertrain warranty (37500 miles). GM did not put us in a comparable rental vehicle, so I had to pay out of pocket expenses outside of their rental allowance for a compact car. Dealer charged for an oil change. Dealer changed the rebuilt engine warranty terms upon pickup from 3yr/100,000miles to 12mo/12,000 miles or the current terms of power train warranty, whichever was longer. GM is well aware of this issue and is keeping it quiet. Rebuilt engines are on back order for months because its that common of a failure.
