EDIT: Okay so the Subaru TSB is finally out, and it DOES specifically state the cause of the chirp and the required new pump and parts, but the COUNTERMEASURE is stated to be a specific corrective method of REASSEMBLY of the whole system to control orientation of the plunger stopper in the HPFP. The Scion TSB did not elaborate on this when I read it!
It makes sense now why the part #'s are kept the same! The incorrect orientation of the hpfp plunger stopper is the root cause of the chirp, can we all agree on this as factual info now?
Those FRS owners who've had the chirps come back likely didn't have the plunger stopper in the HPFP oriented correctly during reassembly.
The Scion TSB should be updated with the crucial info from the Subaru TSB to avoid any misunderstandings about the root cause and the countermeasure! |
I always drive spiritedly....chirp always there....But...I filled up with chevron twice and the chirp went away. It got quieter after first fill up and went away after second chevron fill up. I then filled up with the usual QuickTrip I use and the chirp immediately came back! QuickTrip says others fuels are fruit punch! Then QuickTrip is tap water!
Anyway I had the fuel pump RnR the other day. Chirp is not back, but I have Chevron in the tank right now, gonna use QT just to test it out. However, the new fuel pump is making a noisy clanking/ticking sound
Is this normal? My old pump only had the chirp not the clap I mean clank! This is driving me nuts, Im very ocd and makes me not like the car.
Im also having horrible rattling from door panels when stereo is on. I pin pointed it to the window control switches, brought it to the dealer and they said they didnt notice anything!
Im going back and showing them the rattles and make them fix it. I cant even listen to my stereo in a brand new car with out crappy rattle sounds.
Very unhappy right now with my FR-S
