This is precisely the reason I chose not to modify my STi with a Cobb Accessport. Both flashed and stock cars were grenading their engines but modifying the ECU would totally give Subaru grounds for denying any warranty claim. At this point, I'd just go MPP. Pay to play the mod game.

Tesla denied warranty for Upper control arms because of Aftermarket Suspension
- Thread starter WhiteM3P-
- Start date
When I had my car in for service last, I saw they added the ball joint goop process to my list.
Except I have MPP FUCAs.
So I threw the stock arms in the frunk with a note that said the stock arms were no longer on the car, don't bother taking the frunk liner out. Figured this would allow them to fix my stock arms and get the VIN out of the system.
Nope, they just refused to touch them because "aftermarket arms on the car prevented repair", but they had no issues with any other part of my warranty claims.

Did your MPP FUCA make any difference on how the car drives? I'm scheduled for MPP FUCA install tomorrow.
I think you are missing something here. You might want to consult an attorney, but under the federal Magnusson Moss Warranty Act, Tesla has to prove that your mod caused the issue. You do not have to prove that it didn't. This law was put in place in the 60's and 70's when people were hot rodding their cars. If anything failed, the manufacturer said it was because of the mod and voided the full car warranty. The federal government stepped in and put this law in place with a lot of emphasis on auto manufacturers.
The only point of the MPP FUCA is to run more camber in order to get more grip and/or reduce tire wear on the track.
I don't notice any difference in daily driving with it, but I no longer tear the shoulders off my car on the track, and I do get a bit more grip as expected.
All matters what alignment you run. Not much point in the FUCA if you're staying with stock camber.
Yes, but in the case where you changed your spring rate and height, and now your ball joint which controls the motion of that very suspension system is failing, that's going to be a hard one to prove or disprove. Given the cost here of ~$750 there is no way involving an attorney makes sense (even cheaper if you do the install yourself with used parts)
Nothing like saying when you seat heater fails it's the fault of the spring.
Gonna run stock camber and alignment. Guess the only thing I'll gain is better quality part.
You can try to fight it, but sometimes - you have to pick your battles in what's worth the $$ or even more so - your time.
Eibachs and Swaybars shouldn't cause any issues - they're very minor compared to other suspension options. Feel free to drop by and we can take a look and offer a 2nd opinion. We carry MPP and at least you'll drive off knowing the work is done correctly.

A control arm on Ebay is about $75. Do those and move on.
Spend the $1000 difference on something you'll notice like MPP lower control arm bushings.

Heck, a brand new control arm from Tesla (latest Revision) is under $100
Good meeting you this morning, we'll take a closer look later today and get to the bottom of what's going on.
That's a nice price decrease. When I had the job done back in 2020, the part was $165 and labor was $243.75.

My service center says 100 for the part, and 500 for the install labor. It's two hours of labor per side - and Tesla charges $250/hr for labor.
Apparently some people get reduced rates for labor on the FUCA though.
Great meeting you as well Tom. I wanted to thank you and give everyone an update. So the car no longer creaks and the issue was resolved. As it turns out, it was the bushings on the lower suspension links connected to the subframe. Glad I stopped by. Saved me $1200. Thanks again!
Side note - Don't trust Tesla service center diagnosis. Some of those Tesla
couldn't tell you the difference between a Tesla and a Toyota.
Makes sense to me...I own 2 jeeps and never did anything that would be used against my warranty until it was out of warranty. They will all use it against you.

My local SC techs used to tell me things like: Nobody will care that you have coilovers here, everyone is very chill.
I understand the intentions are good, but no way in hell I'd ever settle for believing that. People change, precedents change, standards & procedures change, **** that. You gotta be ready to bite the bullet if you're going to play this game.

On 4/5/22 I had Tesla replace upper control arms under warranty and I have a MPP suspension. I've had 5 part replacements in 4 years. My request for an extension on my warranty was declined. No surprise. So I've decided to "go public" with all my DEFECTIVE part replacement issues.
Over the years I've owned 2 Honda Civic DXs, 1 Subaru BRZ and 2 Hyundai Tiburons and NEVER had any parts replaced under or at 35K mi. Indeed, I've also owned a 1970 Dodge Dart (RIP!) with over 90K mi and never had repair issues due to defective parts.
Don't even get me started on the numerous recalls.... Got my first recall letter last month.....

If you're out of warranty you're out of warranty - don't quite understand. How many years? How many miles are you at?
Is MPP after market? No idea what that is...but many auto manufactures immediately void warranty (rightly or wrongly) for non OEM parts. I own two jeeps and I don't blame Chrysler for my choices.
Also by numerous recalls and "recall letters" do you mean things like an "over the air" update to disable your boombox
???
