The head gasket blew at ~91,000 miles. It had a dragging/sputtering sensation in idle and then began making a loud noise as I was driving. Dealer replaced the short block and said they rebuilt the rest of the engine because the long block (they admitted that the entire engine needed replacing) was on back order for 2 months. It was covered by the 100,000 warranty. As it stood, the short block took a month to get in. Four months and ~8,000 miles later, the car again had issues. Initially it was thought to be in the engine, and I was told I needed a new engine again. Then they said it was the cooling gasket. Finally they said the coolant system (which connects to the engine) was warped and also needed replacing. They claimed it was no longer under warranty but replaced it anyway in good will. I maintained it was connected to the earlier repair caused by the engine malfunction. On my receipt at pick-up, it said the cooling hoses were soft and would need replacing ASAP, but no one mentioned it to me nor offered to fix it (me paying or not). I read it several hours later after I'd left. I'm over 100,000 miles now and hearing new noises. I'm holding my breath until I can take it in to be checked.
