Manufacturers search forums and blogs.
In today's National Post, Driving section, there is an article about Toyota issuing a "fix" order on Camrys after they noticed lots of discussion about a certain defect plaguing the car.
A spoke’s person for Toyota said that manufacturers who don’t pay attention to websites, chat rooms and blogs “is either clueless or doesn’t care”
Keep on posting those problems and defects here. Lets hope DCX is not among the clueless.
I don't own a Nitro yet. Although I love the look of the vehicle, I am waiting to see how the model measures up in the first year of driving.
