I've had my 2005 HAH in the shop three times about the check engine
light coming on at full throttle. They retrained the high speed
crankshaft position sensor but it still happens. Car gets only 32 MPG
on highway driving (~60 MPH) and 19 MPG in mixed freeway/city driving.
It stumbles at idle too but it generates no computer error codes so it
must be working perfectly.

The 2005 HAH is a dud.
