1 Automatic Emergency Braking problem

Failure Date: 04/20/2024

8:40am Saturday Apr 20 I was driving southbound on hwy 121 in dallas, TX (near spring creek exit) in Tesla modelx, with 2 kids in the back seat. It is raining. My speed is around 60-65mph and I am in the rightmost lane. Suddenly the vehicle skids a little, and my steering wheel and brakes are not working anymore. It seemed that the car took complete control and does a full 360 rotation, crossing 4 lanes on the highway. I recall the 10 seconds when I am facing the incoming cars and the only thought I had "this is the end". For whatever reason, the incoming cars slowdown and my Tesla makes a full circle, crosses 4 lanes again and gets positioned correctly in the flow of the traffic and in the rightmost lane. My speed now is around 20-30 mph and I suddenly regain control of the brakes and the steering wheel. My kids are crying in the backseat. I still am trying to figure out how and what happened, I cant believe I am alive and I did cry thinking that anything could have happened to my kids. We could have all died on the spot given the rain and how fast the highway traffic goes. I am 47 and have been driving for about 30 years. I know how to control minor skidding in rain. I go skiing frequently and can drive on ice (but this was no ice, just water). The only explanation is the malfunction of the Tesla mirrors/cameras (perhaps due to rain water), and taking the wrong decision to swerve the car completely across 4 lanes back and forth. I wish nobody has to go through such life-altering experiences due to a car malfunction, I will never forgive Tesla for the nightmares I still get and the trauma I and my kids had to go through due to the error of a machine. There were no issues before or after with the car, no damage, our tires were relatively new, no police was called. Tesla of course must record incidences like this and they did call me and escalated this to their highest level.

2 Automatic Emergency Braking problem

Failure Date: 10/16/2021

On 10-16-21 Saturday around 7:40 pm, I was going to my brother-in-law's house which is on the left side of the road I was driving. It is a single lane road in a busy residential area. I wanted to park outside of the house by the road. I took a left turn towards the gate, then slight reverse and put in drive to pull to park parallel to the road. My Tesla model-x went into 'sudden unintended acceleration' mode, went left to right to left in a violent way, picking up speed like a rocket. I applied the breaks repeatedly, but the car did not stop and continued to race on the road for about 0. 3 mile where the road takes slight left turn. It went and crashed into a 40 ft tall big pine tree at probably more than 150 mph. It knocked off part of the compound wall of the owner, and passenger front tire blew away and landed in their front yard. I had the seat belt on. No other vehicle involved. I was the only occupant in the vehicle. No fire. I called 911 from my cell phone. I opened the driver side door manually and got out. Police took the report from me and took pictures. The report will be in another 3 days. Ambulance took me to hospital. Broke rt ulna, lumbar 2 vertebra, pneumothorax lt lung with collapse of left lung, s/p chest tube. Also cervical muscle strain/ rupture. Discharge after 3 days. Still lot of back pain. Unable to go to work. Car is total loss. I have Tesla insurance. Reported the accident to insurance. Adjuster still working on the claim. Requested to 'preserve the car' for further investigation. 7-14-when I stop at a light, the front end of car goes up by about 4 inches. Took to Tesla service center and I was told it is adaptive suspension and it is normal. 8-10-21. When I apply break to stop at a red light, and when I turn on left turn signal, power shuts off completely, everything blank in the middle of busy traffic, had to reset power. Very scary. Happened twice. Complained. Tesla remotely updated sd card. Happened again on 10-15-21.
