Another front suspension control arm failure
- Thread starter RDoc
- Start date
To me it looks like a design fault. That little bit of metal might be enough if it's made of titanium, but aluminium alloys, I think not.
We have some rough roads and while I take them at low speed I don't like the look of it.
Hi there,
I just had the same control arm break free issue and here is my link:
Model X arm control disconnects from wheel at low speed
So what did the dealer do with your car in the end? Are you happy with their arrangement?
Thank you
Eric
Sitting on street as this just happened to me. Driver side control arm snapped while exiting a parking lot on left turn.
What's interesting is there was early sign for me. I was scheduled to have a rattling noise look at tomorrow for the front left suspension and this happened. The rattling sound is a low speed rattle sound that others have been reporting but inclusive in resolution.
Will post pics later. This is a 2016 75D facelift with 55k km.

This is not the only design flaw. Some of the ball joints made in Canada fail and sheer off causing the wheel to go back into the wheel well. I have seen this on two cars and IMO it needs a recall. Tesla won't admit the failure as it is a liability but the steel appears to have defective casting and is too brittle causing it to shatter after a pothole or low impact. The set up a TSB only on one year car and only if it is in for alignment.
Just another reason to have service coverage out of warranty. X-Care covers suspension issues state in this thread.

Extended Warranty News Flash !!
Not needed if this happens at speed. My friend was doing 30 and hit the curb as you loose all steering. His wife's failed 6 months later, luckily no one was hurt.
Originally, they just replaced the part that failed, but in my comments, I said we weren't happy that they just replaced one side. Months later when I had the car in for another(!) problem, they replaced the other side gratis without my asking. I was, and am, very thankful they did.
Eventually, with some prodding, they also replaced the fender liner that the wheel rubbed against. They didn't have the part earlier but had noted it on the service report.

I didn't lose steering, in fact I drove about 4 miles or so to get home although it was pretty noisy with the tire rubbing on the fender liner. Tesla flatbedded it from there.
Interesting. For me it was both *rear* suspension control arms failing without any road impact (one at a time). Yeah, I do think they have a systemic problem. In areas with consistently bad roads, maybe the original version of these parts just aren't strong enough.
Ah, good to know. A systemic problem which is already addressed is the best sort.
Even better. That's what I suspected with my failiures: a bad batch of parts.
That's what happened to me. Lost both of the rears in about three months. Tesla replaced under extended warranty.

My right side failed. There was a low speed rattle on that side only that Tesla checked and said was normal. It’s all being reconstructed now but should I worry about the other side? 2.5 months without a car sucks royally.
What do you mean reconstructed? How much damage was there and what speed were you going?

I was moving at highway speed. The front bumper, headlight, quarter panel and a long list of expensive stuff was damaged by the failure. It’s very difficult to know what (if anything) I could have hit. It was dark and raining but lots of other Cars were transmitting the same area without incident. Total repair greater than 20k.

Absolutely you should worry about the other side! See my previous post below:
Nine months ago, my 2015 P90D's right Forelink cracked and Tesla replaced it.
After reading of other Forelink failures, I suspected a bad batch, so I asked them to replace my other one. They said there was no need to replace it and there was no recall, so I shouldn't worry.
Seven months later that other Forelink cracked exactly the same way. When they replaced it, they also replaced the steering knuckle, which they said was damaged. See the TMC thread entitled "Cracked Forelink?" for my photos and more info.
The second time, the service writer said they see many cracked Forelinks but they all seem to crack backing out of driveways and not on the highway. My thought was that he doesn't see the ones that fail on the highway because those cars are towed to the salvage yard instead of the service center
