What owners wrote
The engine caught fire while sitting in my garage. I had driven it for a few hours doing deliveries for a store and parked it in my garage around 2:30pm. About 1.5 hours later, my wife was coming home and opened the garage door and saw smoke above the hood of my car and then a few seconds later it burst into flames. I believe that it was smouldering for a while and the gust of wind when the big garage door opened gave it the extra push to ignite.
Head gasket 77,000 miles with the head gasket issue the car engine was shaking when it's warming up. The car log showed misfires in 1st and 4th cylinders.
