Front Suspension Control Arm problems of the 2018 Tesla Model 3

During low speed, bolts became loose and completely dropped out of lower control arm causing one wheel to veer to the right. Very concerning that critical steering components do not have a castle nut and cotter pin, if this would have been high-speed there could have been loss of life. Tesla is failing to address concerns of safety, there are numerous other reports of these bolts coming loose. Consumer concerned about the noise and vibration while driving and brought the car in for inspection on 9/1/20 to a Tesla dealer. Dealer stated rim was bent which caused the vibration and the bolts became loose after an impact with a speed bump. Consumer having a hard time understanding how low speed impact could cause a grade 8 bolt to become loose.

The car was pulling very hard to the left. Took it to Tesla service center. They gave me an estimate of nearly $6000 to replace control arms and bushings and steering rack etc. They said the parts were damaged from "outside influence". Whatever that means. The car is 18 months old and has 29,000 miles. No accidents or damage ever. This is a major manufacturing defect that could have had disastrous outcomes if I did not pick up on the symptoms first. This is in absolutely no way related to any "outside influence". This is a defect plain and simple, and a major public safety issue, to say the least. Tesla refused to cover the repairs under warranty, and I am trying to work though the California arbitration process now. I will have to rent a vehicle for weeks out of pocket while this process is pending.

While in motion, the vehicle creaks and squeaks from the suspension area. Control arms go bad prematurely and could cause a crash and or damage to the vehicle.

The control arms and links for the car keeps failing. I have taken it into Tesla on 3 times now to have these repairs made and the car is only 2 years old with 40k miles.

Control arm squeaking and both replaced one under warranty and one out of pocket , Tesla recalled cars in china also for this https://. . Read more...

Control arm, upper rh damaged or broken. Loud squealing noise when driving at lower speeds 0-30 mph. Has gotten increasingly worse the past day or so. Tesla technician set an appointment to replace and said it was a known defective part from the manufacturing process. I am seriously concerned about the lh control arm part and if that needs to be inspected and potentially replaced.

I am having issues twice in 2 years my upper control arm is making very bad noise while driving then get it replaced then from right side failed again and keep making noise while driving then I got this replaced. I never had this type of issues before in last 30 years for new cars. Once it happened at 15,000 miles then again around 35,000 miles. Now may be soon again. Thanks anil.

Over 5000 miles of driving, there is a significant amount of vibration and buffeting in car at any speed over 45mph. Tesla service has had eight opportunities to resolve this, to no avail. The tires have been replaced to eliminate this as a possibility, and the wheels checked for runout - all measure very good. Suspension components or control arms are the likely culprits. In addition to the suspension components failing after less than 5000 miles, the drivers seats on most all Model 3 are loose and rock back and forth, with Tesla saying it is 'within specifications'. This could be another serious safety concern in the event of a crash, as it is unclear why the seat disturbing becomes loose with normal use. After discussing with other Model 3 owners with identical issues, it is clear that this is a inherent vehicle / parts problem, and Tesla is doing the least possible to address these concerns.

Ball joint failure leading to need to replace upper control arm on drivers side. 2nd instance in less than a year. 2018 Model 3 with less than 40,000 miles.
