New TSB for 3.5 GDI Sartup Rattle 15-0131

they do have a top notch body shop so I'm not worried about the paint work. I guess they screwed up the terminal trying to get the cable off to make the repair. I had it on pretty tight so I guess it bit into the terminal, of course no one else takes care of our cars like we do. I would have spent all day trying to remove the cable before screwing up my battery. Yeah he used a little pulley puller jaws of like this to push the terminal out of the cable connector. Dumb.
 
So i still have this Flex and drive it everyday, it now has 125,000 miles on it and i have been dealing with the startup noise for 120,000 miles and endless trips to the dealer and they couldn't figure it out. I bet they just believe it was a stretched timing chain. Well last weekend i finally took the valve cover off on the front to confirm if i had the old chain set up or the newer one. Luckily i have the newer chain and its never came in contact with anything, not a mark on it. So i was boggled and just changed the VVT solenoid out of pure curiosity and low and behold the start up rattle went away for the first time in many many years. its very frustrating to say the least. I have had to deal with this super loud rattle for 120,000 miles and all the dealer had to do is diagnose the car correctly and fix it, but that never happened.

That is good news.  How permanent it is remains to be seen, but fingers crossed! :)

Well probably shouldn’t have spoke so soon, it’s only been 3 days. I just left work and it did make a slight rattle on cold start up. The crazy thing is that it has to be something to do with the right side VVT solenoid because all I did was change it and the rattle went away for days. Now that I think about it when I took my car under warranty many many times to the dealer for this rattle when I picked it up most times the rattle was gone for a few days after, I use to think because it wasn’t being driven for a few days but now maybe it’s because they  reflash the computer and reset the solenoid. Please if anyone can offer anything on this please help
