My car (2012 S85 VIN 2204 CPO) has been in Fremont service for 3 times now for the same problem and still is not completely fixed, so I am hoping to get some suggestions from people here. The problem was that I was hearing creaking/groaning/rattling noises from the front left suspension area whenever I was driving at low speeds around 10-15 mph and was doing light acceleration/deceleration. Basically it felt like when stress was being placed on the suspension it was making the noise. Visit 1: I did a road test with a tech and thought they understood what I was talking about, but unfortunately they thought I was referring to a different sound and ended up fixing that instead. So obviously my problem was not resolved, so I had to bring the car back. Visit 2: I did a road test again, and this time they understood my problem. At this point the sound was still easy to reproduce, so the tech worked on it, found free play in the upper control arm, replaced it, and said problem went away. I thought so too based on forum searches here of similar symptoms. I drove it home and found the noise was still there, although harder to reproduce now. Comes and goes depending on mood of the car. I found a service bulletin relating to control arm washer replacement (SB-10057891-9353 Front Lower Control Arm Washer Installation), thought maybe that was the problem. They checked and said bulletin was already performed in 2015. Visit 3: At this point I'm running out of ideas, so I sent the car back. This time the tech claims the noise is caused by items in the frunk, and that after he emptied the frunk, the noise went away. I told them this was an incorrect assessment because even with the frunk empty I had heard the noise before. So they call me down for a road test yet again but unfortunately the car was moody and wouldn't make the sound except once or twice but not as loud as normally. I asked if they can look at the suspension again since we heard the noise again. Tech says they already checked everything and found no issues, and that since the problem is so intermittent, unless I can find a way to reliability reproduce the noise, they don't know what else to fix. Of course a few days after getting the car back the noise is back loud and clear, so obviously issue has not been fully resolved. So now I don't know what to do. The suspension problem still exists because I can hear it every other day or so, but they claim the car is fine unless I can prove to them there is a problem that can be consistently reproduced. Any suggestions?
