I just had my 2016 Model X (Rear, Driver-side) control arm failure as I was about to get onto the highway. I made a left-hand turn and heard a clunk (thought it was a rock or gravel) and then noticed car pulling to the left. I tried to pull over to inspect just before getting onto the highway (~10 meters) and the wheel completely falls into the tire-well (and is no longer drivable).

Out of warranty, so close to $6000 (Canadian) in repairs. They claim it's normal wear and tear. Some disagree. Do these need to get inspected/replaced every 6 years to ensure this doesn't happen?

I'm just thankful it didn't fail a short time later while I was driving 100km/h on the highway.
 
Hopefully it was a defective part and not just one of many parts the road salt has eaten.
How many kms on the odometer?
Odometer has 122,621 km (76,193 miles). I do try to keep the car well maintained. It's parked in a garage every night and it regularly gets washed (more frequently in winter). When I switch over tires (winter / summer), I service the brakes. I'm certain it's not road salt. It's either a under-designed/defective part or it was not installed correctly. Control arms are designed to be properly tightened, if loose, they will catastrophically fail. I've seen it happen on our University Solar Powered Race car back in the 90's.

But I'm not the first to report this issue. This appears to be a common complaint and there is an existing Class Action lawsuit. Might need to investigate better-designed after-market parts.

They have a new part number if you were on the original. It was a poorly manufactured part, not wear and to tear. File a report with your equivalent of the NTHSA and raise a stink.
