For some context you can read my previous thread: How to get service to fix problem that is hard to reproduce? Basically I started hearing weird groaning/creaking/rattling noises from my front left suspension recently, but only when driving local streets under certain conditions and only intermittently. I have brought it into the Fremont Service center total of 4 times now. So far they have replaced the upper control arm, the sway bar, and cleaned, re-torqued, and lubricated all the suspension parts. They claim they do not see anything else wrong with the suspension (ie sway bar end links, mounts, bushings...) For the most recent visit I even left the car with them for 1.5 weeks so the tech could reproduce the problem driving to and from work. He reproduced it and swears that by replacing the sway bar the noise has gone away. Unfortunately a few days later I started hearing the same noises again. The people at Fremont Service have been very patient and nice about everything, but they just can't seem to fix the problem. Every time I go back in, they just keep asking me to go on road tests with the techs, which I am getting sick of and doesn't really help since the problem comes and goes and is hard to reproduce. At this point I am not sure what to do. Part of me wants to just say screw it and just drive the damn thing, and maybe turn up the music to cover up any noises. But the other part of me says something is definitely still wrong and should be fixed, which involves wasting more time running in circles at the service center. Any advice for situations like this?
