There are 2 owner-reported powertrain & transmission complaints for the 2021 Tesla Model Sin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
7/30/2025 The vehicle experienced a confirmed TOTAL loss of function to include steering, restraint, and braking functionality at approximately 60 to 65 miles per hour. This catastrophic failure placed myself and and others at severe risk. Although Tesla’s service notes confirm the event occurred, no corrective repair was performed. The vehicle was completely inoperative with a matter of seconds with no prior warning. At this point in time the car has continued to not operate the same steering and noises has been in the shop 5 times still no answer or repairs in regard to it shutting down or any other issues that continue to return. The last visit I was asked to purchase new tires because maybe that’s why, I did. I continue to be told nothing is wrong with the vehicle making me feel extremely defeated when I know the vehicle is not the same as it was.
Front axle half shafts have failed two times requiring replacement (on 3rd set now). During acceleration the steering wheel vibrates violently. Tesla service center diagnosed both times that front half shafts needed to be replaced. There seems to be some design or manufacturing problem - these items keep failing. The cost to fix is ~$1,650 so I delayed as long as possible until vibration became unbarable. First replacement was done under warranty, second replacement was required ~16,000 later and I was forced to pay for it. There is a Tesla service bulletin about this which I saw online.
