As long as MAN builds machines, they will never be perfect.
Whether it's Infiniti or any other car company, there are always problems, especially if you are dealing with a vehicle in it's first year on the road just like the '04 GTO. That's why people say never to buy the first year model of a car...all the kinks are not worked out.
My brother has a new BMW and it's been to the dealship several times already for repairs. I know someone who worked for BMW and they've had so many recalls on the cars with problems but alot of the problems were caught just after the ship dropped them off here. Some problems, depending on the model were faulty cooling fans not cooling the engine causing overheating and fires under the hood, another problem was faulty navigation equipment, another problem was faulty traction stabilizors that caused the SUV to lose control and/or tip over.
And that's just BMW...all that money and there are still problems. So like I said, so long as MAN builds machines, there will always be error.
