Door ajar warning always when you open the driver's door, and it can stay on for hours even when the door is definitely closed.
This is a very fuel efficient and fun to drive little truck. However, I really wish that it wasn't so gutless from 3 gear and up. When you mash the throttle to the floor in 5th gear, the speedo barely moves at all.
When I put a Flowmaster and K&N cold air intake in it, it definitely helped, but it doesn't do much on the top end when you are getting up to highway speeds.
That said, it is a great daily driver, it handles well on all surfaces and nothing has gone wrong. Its great to travel in besides for the lack of cruise control, and it is really solid with no squeaks and rattles.
The only thing that drives me nuts is how the door beeper can stay on for so long and not go off. I hope to have it taken out though. Also the windshield wipers in my truck seem to have a mind of their own.
Those gutless 4th and 5th gears are what give you good fuel economy.
