A week after I spent $1000 on maintenance, the drivetrain malfunction light came on while I was driving to work. I made it safely off the highway and to the dealership (Bill Jacobs, Naperville, IL). They hooked it up to the computer and it showed a fault code and they indicated that the code pointed to a fuel system failure but they would let me know for sure. They gave me a loaner and sent me on my way. Later in the day I was called and it was confirmed that the fuel pump failed. They replaced it under an extended warranty.
