2025 LR upper control arm replacement

Had a really annoying squeak for a while. Turned out there were two causes. First the drivers seat squeaks - this goes away when you move it and is best diagnosed by shifting your weight around in the seat when stationary. There is a fix for this but I moved it to a different spot and it completely stopped. Having fixed that I still had small squeak that worsened when the weather warmed up. Only noticeable at low speed, worse on flatter roads weirdly. But progressed to a squeak when turning the wheel when stationary again. Took it in - they replaced the front upper control arms, bushings under warranty. They were very worn and split. Cars done 12k miles so hope these work better. Just a PSA to anyone else with a squeaky Highland.

Yeah, cranking the wheel at a dead stop will put additional unNEEDED strain on steering components. Can you do it? Sure. Will it decrease service life of the components? Absolutely.

It’s a way of diagnosing it not a recommendation lol

Picked up a brand new 2026 model 3. The first time we went over a speed bump the car creaked and groaned. Its a known issue and was replaced under warranty https://preview.redd.it/e42lsjd80oog1.jpeg?width=1230&format=pjpg&auto=webp&s=fe7b376cdcc6fce73d415d6e34d33d5c9f0e7700

How are these still an issue? I had mine replaced under warranty due to early failure as well. 2019 model 3

I don’t know - I’d heard of it with the pre-highland model. But the suspension for Highland is ‘improved’ so…

Yea had mine replaced on my 2018 at 60,000 miles. Not under warranty $256.00

Thats not too bad consider their repair prices. I was expecting 1k.

I also warranty swapped mine at 12k. Im at 19k and i can hear it slightly again. Sounds like its coming from the right so Ill wait until its even and annoying. Did they charge you for an alignment?

No it was all under warranty

One reason the first non cosmetic mods to my car will be the mountain pass front upper arms and solid lower arm bushings. Probably also get the front stock size brake and pad upgrade. And master cylinder stiffening bracket. I do intend to track and autocross the car. Will worry about the rear only if my alignment is out its going in next week for an alignment as I just put a new set of all weather's on it and will be buying track rims/tires in coming months. It does pull slightly to the right I'm hoping that's just front toe.

Did you need to pay the diagnosis fee? They are wanting $188 to “find the problem and sounds,” when I know it’s the upper control arms that are failing on mine. I even asked if it would be under warranty and they said they would have to diagnose and that would cost to see if it’s failing and would be covered under warranty.

There was no charge although you have to agree to the inspection fee
