As I mentioned, I drive my Panny 90% on weekends only, but when I do drive it certain driving tactics scare me because I just know that the noise will be there. Right now, if I make a sharp turn with the front wheels turn at full angle, the suspension sounds like it's about to just fall out. It's even worse when on slick surface, like now when we are getting a few drops of rain here in Cali. You all may just want to try this and see if you get the same results. You can even back out of a driveway and turn the wheel sharp right or left, or try making a very sharp U-turn and see what you hear. I thought maybe this may be because my tread is low (have about 4K left), but I know it can't be just the tires. Now, as for the other noises, I really have not heard much else, except for the rear hatch on occasion but I can for sure live with that. But I do a lot of highway driving when I do drive, and my music is blasting so maybe I'm drowning out all the other noises
So, as for now I guess I'm OK with driving my Panny, but I honestly can say that I would probably not purchase another one unless I drove it for a while to confirm these "normal" noises are no longer present. I know for sure the front end noise is no way normal. I have Hondas, Acuras, and even a Jeep Wrangler and have never been to the dealer for more issues combined than I have with my Panny! I love the Panny, but honestly $100K plus on a car should not warrant such issues and concerns.

I met with the factory rep last Friday. Nice guy. After a brief drive together, I return next Monday as he had dealer order a complete strut assembly and lower control arm for driver front. This is in attempt to fix the clunk noise from a stop. The clunking/linkage noises heard coming to a stop he said was the PDK downshifting. Could be, but I don't hear this in other Panamera's I've driven nor has anyone responded yes to my thread asking if this was noticeable in other forums members cars. There is also substantial pinging in the engine. He ordered a decarbonization of the engine, whatever that means. I have two pings. One is a more constant pinging and the other is a much louder short term ping at certain times. While we didn't get to address some of the other issues like the rear crunching, he told me these noises are normal, for the most part. Im still working on a more satisfactory resolution encompassing most or all of the issues. Regarding interior noises, he wants them to be more consistent before he tackles them. Despite my having audio recordings illustrating them, I guess if I only have it occur 1/2 the time, that's acceptable in their eyes. Lol. In all fairness, the dash would have to be removed and replaced to attempt to fix these. I'm not find of that idea, nor was he. Dilemma.

On a side note, the Michelin PSS I inquired about came in to tire dealer. Asked me if I still wanted them. Told him yes, depending on outcome of my next service.

You wouldn't happen to have a wiggly tach needle would you (thinking this is going to be a sensor/coil issue).

As far as decarbonization - we used to do that on our 2 stroke boat engines. I would NOT expect to have to do it to a modern engine - but then again, as much Mobil 1 as these engines drink, I guess it's no surprise.

As for interior noises - I haven't even gone down the path. At least those I can drown out with the burmester.

I've pretty much made up my mind, I'm done with the car. Obviously it's the best driving car I've personally owned, but I'm not willing to deal with this for a daily driver.

However, now with a creaking noise when turning wheel and going up/over an incline; such as entering a driveway. Different from front end noise that i had before - ugh - back to dealer? Not sure what it is now.....

Are you sure you're not hearing tire skip? Mine did that when backing out of my driveway in the morning (cold air, cold tires). Everyone says it is normal for Porsche and maybe because of AWS (had a 4S). Interestingly, my BMW 550 with x drive does not skip the front tires having driven it even in single digit temps and the BMW has almost as much tire on the road as the Porsche.

His response? Yep. Invoice I saw for control arms alone was 1500 each! This was one of the reasons I decided to get out of the car.
