2018 Volkswagen Tiguan body & structure problems

The drivers side b pillar consistantly makes agressive and loud cracking noises when driving the vehicle. I have initiated a lemon law suit with volkswagen. The vehicle has been to the dealer three times and the concern has not yet been rectified. Additionally the drivers side b piller flexes and cracks when the rear drivers side door is opened (the door is attached to this pillar). The second dealership was able to replicate the noise was was very concerned.

Vehicle was making a small annoying rattling sound, emanating from the driver side b-pillar, next to driver's head. Rattle had been intermittent initially but by 8,000 miles on the vehicle the rattle was almost constant at any speed whilst being driven over any surface smooth or otherwise. We took the vehicle to our local volkswagen dealership and it has now been there for 32 days. A repair was done, but the result was satisfactory, so they are trying to repair it again.
