Wondering if anyone else has experienced this or found solution? Practically straight out of the dealership, the driver side high performance seat makes unacceptable and annoying creaking noises over any road imperfections which torque or twist the main car body. I THINK if have it narrowed down to somewhere around/in all the plastic backing on the seat shell. Moving my body around vigorously doesn’t really evoke the sound. It is mostly linked to the bumps and body twisting on the road. **** ANNOYING for a brand new car let alone one in this price bracket. Traded a Porsche for it which had very high build quality. Driving a base model Audi A3 Sportback while waiting for the delivery and it has 5000 km on it and no rattles or creaks at all. From what I can read on this forum it seems the build quality of the A45/A45S/A35 seems to be hit or miss which really surprises me and wasn’t something I even considered before purchasing the car! Anyone found any solutions or ideas? I will of course have the dealer try to resolve it...but I can just picture 5+ visits with no solution or resolution for such types of niggling annoyances.
