The steering system failed. I'm not sure about the availability for inspection. My safety was put at risk when my car collided with another car. I had just pulled out of my driveway and turned to go down the street a short distance from a stop sign where I would turn left. From a video taken by one of the car's cameras, the car went to the left side of the street and started toward the intersection where the car hit another vehicle. I have driven to the intersection numerous times. There is no way that I would have pulled toward the left side of the street. I believe that something in the steering system malfunctioned. This put me and other drivers on the road at risk. I don't know if the the problem has reproduced. There was a policeman at the site, but he would not inspect the vehicle for a malfunction. …
The contact owns a 2018 Tesla Model 3. The contact stated while driving at approximately 35 MPH, the Front Passenger Safety Restraint System (FPSRS) fault warning illuminated.

This car was hit in a T bone on March 15th 2022 by a Toyota RAV4 on the driver side , the driver side was completely smashed and the car spun 2 times and came in the middle ramp. In spite of this heavy impact there were no airbags deployed , after several follow ups with Tesla I have no answer so far. The car was deemed total loss last month and even after consistent follow ups I have no answer from. Tesla. The impact was very heavy that my wife had whiplash and she went through chiropractic treatment for 2 months .. I'm very worried as the impact was so bad that this is a fatal flaw in Tesla and they do not have the airbag curtain deploy to protect the driver side at all - my wife was lucky and she is alive but this could happen to anyone .. …

My car left the road traveling at 60mph, and after leaving the road it was quickly approaching a metal pole. At this time it seemed that the breaks were not able to stop the vehicle. After totaling the car, and what I thought would be the loss of my life, my airbags did not deploy. To further explain the extent of the accident: the front bumper is destroyed, the hood is destroyed, the windshield is destroyed and caved in onto me, the roof was destroyed, the back glass was also destroyed, along with much more extensive damage to the build of the car. The pole involved in the accident came out of the ground and through the car. It is unfathomable how I am still alive with manageable injuries. Yet- no airbags. This could have ended much differently.
The contact owns a 2018 Tesla Model 3. The contact stated while driving at an undisclosed speed, a message was displayed alerting the driver to a passenger safety restraint fault. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular failure. The air bag warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to the NHTSA Campaign Number: 21V389000 (Seat Belts) but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 60,000.
I was involved in a rear-end collision where I was completely stopped at a green light due to traffic congestion and the person driving behind me hit my car from behind that caused me to hit the car in front of me. The impact was hard that the Tesla model 3 immediately turned on the hazard lights and called 911. The screen of my Tesla model 3 stated "airbag deployed;" however, no airbags deployed. The Tesla immediately became inoperable and did not let me drive the car to the side of the road out of traffic. Also, the Tesla did not let me change to towing mode (since the screen eventually went black); which made it more difficult to tow the vehicle out of the way of traffic.

The contact stated that the front driver's side wiring harness was defective. The wiring harness was replaced and the vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 58,000.
