As long as the OP has contacted his dealer, the forum is the perfect place to show frustration. He took the proper steps to get it corrected. Its the second time its happened. Anyone would be frustrated. Now its up to customer service to step in. If the job is done well, and he is satisfied, than he should return back to this thread and update.
Its not that Vexus doesnt make an excellent product, as there are plenty satisfied customers. Every new company has its growing pains, and Vexus has done well.
If the cracks continue, than it may just need some design attention.
Ranting or venting is not just specific to the Vexus forum. It happens on all of them.
