On two occasions brand new (3000 mile)
Santa Fe hybrid lost power and shook significantly on a trip in Wyoming on steep incline. C2 Car transported back to dealer. Computer registers 2 cylinder misfires. But car now operates normally. Has anyone else had this problem?

I found this on the Hyundai Santa Fe forums that may explain your problem - Dangerous loss of power uphill
