check with the Ascent forum's parts guy (I do not recall his name or contact, but it is here). Maybe someone will chime in with his name and contact info.I believe it was on a Facebook group however I've been unable to find it again. I searched the part number and it comes up with limited information. I just want to make sure I get the most up to date parts.
Sherlock would be proud.Hmm...it is in the electronic parts information on the website, and has a price...but it looks like there's not any vehicle application information yet. The "C" pads are still listed for the Ascent if you look up by vehicle. If you change the parts suffix to "E", then it says the part number is not found...so the "D" part number does appear to be legitimate.
I am curious as to what has changed in the design for each revision. I recall one revision included removing some pad area (cutout). I do not know what the other revisions included, nor what this one might include. As a novice mechanic at best I can not figure out why the design is so difficult to get right. Brake pad design has been around for a long time. Why in the world would this original design have to be so different to require four revisions? In my mind this points to poor design processes such that the design did not go through proper testing prior to release. I hope and suspect they are not only getting the design right on this 4th revision but also reworked the design process. I am sure most of us do not appreciate a Microsoft software release approach.The part number would leave me to believe, as you all also speculated, that this may be another version for the Ascent. If so, once the parts database is updated to reflect supersessions, the info pages will show the proper info. That can sometimes take a little longer.
Other than the chamfer on one of the revisions, what else was changed?Hmmm... I've seen arbitrary pricing on things not yet in the parts channel before. At CompUSA, our system would "penny price" things that weren't yet assigned details. Employees would know that, and try to pre-purchase things on the night inventory came in, before the selling date the next day. I've seen other companies that price at the other extreme, with ridiculously high prices, like "$99,999.99" for a ten dollar part.
I suspect we will know soon. Please share anything you learn in the next couple of weeks.
Or, it's the path of cheapest resolution for a different root cause. Maybe the rotor metallurgy, design or manufacturing is wrong. Maybe the caliper slides don't properly align the pads. Maybe the caliper pistons are introducing a non-parallel force to the pads.Brake pad design has been around for a long time.

the bad news is that for many the issue persists (I have not had any brake problems for my 2019). The good news is that clearly Subaru is working the problem and takes it seriously. They have a built in incentive to find a fix, as it cost them more to fumble around with revisions that do not work. It is frustrating for owners interacting with dealerships who are as stumped as anyone. they do not control the brake products and can only go by what the Subaru engineers suggest as solution pathways. The dealerships would prefer to fix it the first time. If I had this problem, I would demand that Subaru extend the brake warranty with a focus on both pads and rotors (but not limited to these) including the option of using aftermarket products.Or, it's the path of cheapest resolution for a different root cause.

The inconsistency of the issue would point to a variable that the pad replacements aren't addressing. The recurrence of the issue after updated pads are installed points to that variable not being addressed ie, elsewhere in the brake system or even the environment or driving conditions.
Is what I was alluding to when I wroteI am very sure the inconsistency is human.
Trying to avoid owners taking umbrage assuming that their driving behavior could cause a mechanical issue....even the environment or driving conditions
Never underestimate the power of the accountants in this equation. Forty years at the three largest technology manufacturers in the world, I can tell you that engineering frequently lost battles to accounting. Even when the fix was readily implementable and inexpensive. Accountants never have to wear the egg on their faces.They have a built in incentive to find a fix, as it cost them more to fumble around with revisions
