Hoping your New Year is less troublesome also.
Having recently purchased a 16 MKC and being an infrequent visitor to the forum one cannot miss the multitude of problems you have incurred.
Have you investigated your states Lemon Law process? Thk you live in NJ and a quick Google chk indicates you have what appears to be a robust program that does not require a lawyer.
I've had two friends here in CA use our program successfully without legal assistance and they were quite happy with a sad problem.
You deserve better than what you have experienced!
