I have been dealing with a modern softer suspension, VIN ~9000, but it makes a noise on speed bumps. Only the front driver's side. I took it in and they replaced the parts but the symptom did not go away. They told me they had used the part version D and would have to wait for a new revision to try again. I just was at the opening of the new Fremont service facility and they said the version E is out and ordered it for me.
It's an odd issue, really ONLY hear it on speed bumps, but it's a new car, I spent all my savings on, I'll be happy to have it perfect. The rear passenger door handle sticks open too, hopefully, it will all be perfect soon. They did replace the missing bolt on the bottom of the car, I wouldn't have discovered if I hadn't taken off the rear bumper to put on the trailer hitch. OK, that's all the issues the car came with.
