You can see a listing of Technical Service Bulletins issued by Subaru for the BRZ by clicking on "Online Reference" and selecting BRZ. NOTE: Because Subaru charges you or me for access time for unlimited online viewing of any/all TSBs---via either a 72 hr subscription ($35), 30 day subscription ($300), or annual subscription ($2500)---seeing anything more than just the title of the TSB will cost you, but at least you can see what "official" TSBs exist for the BRZ, and some of them, at least by their TSB titles, seem very intriguing.
With all of the anecdotal "Do YOU have this issue/problem/experience...?" going around in dozens of Forum discussions, this might be a very useful site to check periodically! Or check with your local Subaru dealer, of course.
On 10/3, Subaru release a TSB for "high-pitched chirp, squeaks, or cricket sounds." I was alerted by one of our customers (also forum member) over the weekend and just confirmed it with my chief technician this morning. There is a note on the TSB that not all pumps may exhibit this sound (seems like they're going to address it on a case-to-case basis). The noise is attributed to a "plunger stopper position" that causes this sound at idle due to aeration of the fuel within the body of the pump. The TSB also note that any "clack" or mechincal "ticking" might also be heard, but that's a normal characteristic from the high-pressure fuel pump used in this car (probably from the Toyota's D4S fuel injection system). This TSB is in affect for VIN numbers D*603383 or engine# 844658 (my assumption is this is for cars with this VIN or earlier or production date of 7/27/2012 or earlier).
From the TSB note, it looks like they're replacing the fuel pump assembly and related gaskets and seals. Any cars built with later VIN is apparently already had new pump assembly installed to avoid future noise issues.
The noise is usually heard once the vehicle is warmed up to normal operating temperature (after 10 min or so road test).
Personal note: how the hell do you classify a "chirp" or "cricket" vs. a "tick" ? Also, don't think this is the same as CEL and idle dip issues reported by others. If anyone has any info on those items, please do share.
Just had someone ask in the other thread about the TSB regarding engine repprogamming for idle issue: that's only for Legacy and outback. I had one of the service guys verified as I was thinking it was for the BRZ.
Just left dealer they ordered parts to fix tsb for hp fuel pump holding off on replacing small front windows because I will have 2 pay to have it retinted hope they come out with a better design!cricket noise is NOT NORMAL!
There is now a new Product/Campaign Bulletin on the Subaru's TSB in regards to ECM reprogramming. It was made available on 10/26. I believe this is the fix for idle dip. Will try to provide more info later on today.
The crazy part is they released the VIN range for cars that would be affected by this reflash campaign, but no actual reflash software. Threw us for a loop. I even had a customer come in thinking that we were good to go only to find out when he's here that we didn't have the necessary software to reflash his BRZ. We have every software packet for this campaign except for the BRZ. Go figure...
