Are you sure you really want the cons and not the pros? Anyway, I'm also driving this van so shoot me, hehehe.
- Hyundai AT still needs more refinement, unacceptable shift lag.
- Spare tire mount needs more security locks.
- Door handles need to be reinforced with metal brackets, the plastics easily break off if pulled in a jerky manner.
- Single rear passenger door is too heavy to close for female or juvenile passengers.
- Grab bars should be placed for easy ingress.
- Stiffer suspension for more controlled response.
- Employ LSD as a standard equipt not only in high end models.
- 5 year anti-rust warranty would also be useful.
- More detailed cluster dials; voltmeter and oil pressure gauge could be useful.
Edit: (I forgot to add)
- Built in turbo timer could be useful too and help prolong the engine life.
