During rush hour traffic on Highway 101 Southbound near Redwood City, I experienced an incident while utilizing AutoPilot and AutoSteer. Despite being in stop-and-go traffic, the vehicle did not respond to the car in front which suddenly came to a complete stop. Neither the Automatic Emergency Braking system nor warning sounds, which has been known to activate erroneously, were triggered. As a result, I was forced to manually brake at the last moment, but there was not enough time for manual intervention and the vehicle collided with the car in front. It is worth noting that every other instance in which I have utilized AutoPilot and AutoSteer, which occurs on nearly every trip I take, the vehicle has been able to respond and brake, albeit with slow reaction times and close distances.
I was at a stoplight behind a Toyota Tacoma. I must have stopped around 8 feet behind it. I was not using FSD and I was not one-pedal driving. My foot was on the brake. I must have been at a complete stop for approximately 10 seconds when my Model 3 suddenly accelerated full throttle on its own and rear ended the Tacoma, directly hitting its trailer hitch, causing my car's driver-side airbags to deploy. When it happened, the light was still red and my foot was still on the brake. I never touched the accelerator. Luckily I was driving alone. After the inital contact, my car sort of bounced off of his hitch then slowly lurched forward before it stopped. After that, it was immobile, leaving me stuck in traffic until it was towed away.
Car was stop at left turn lane waiting for light to change to green arrow. Car just accelerated on its own . Car crashes into to car in front of me and pushes us onto center island and continues to accelerate sending us on to crossing traffic, endangering others and my family life . Tesla never investigated or tried to respond. Insurance company couldn't or never did any investigation and made me at fault for the accident. Tesla certified body shop told me they can't pre scan Tesla and print out reports like any other vehicle. Cars driver front camera was coming on and off prior to acceleration for no apparent reason . Camera is part of ADAS system.
The enhanced autopilot failed to recognize a divider/Jersey barrier or alert the driver of the obstacle, as the software is advertised and was relied on to do, at an exit ramp and ran into the barrier without any type of maneuver or breaking to avoid the collision causing substantial injury to the driver. This exit is a very busy exit on I-95 with many commuters going to work at this time. It was by sheer luck that no other vehicles were involved. The driver endured an immediate stop from above 50mph to 0 in about a second. As far as I know, no inspection was performed. There were no warning messages, symptoms or problems related prior to the incident.
While attempting to park the car in a parking lot, the car did not respond to the release of the accelerator or the press of the brake but just continued. Car continued to jump the curb and run into a concrete wall without slowing or stopping. No auto functions were enabled on the car. Car was attempting to park in the spot on the right side of the photo but just continued on and ran into the stone wall.
I was exiting the highway onto a Blvd and I slowed down. The car all of a sudden accelerated by itself, went over the exit curb and hit the central median of the blvd. Fortunately, no vehicles on the blvd wer crossing when this happened. I was fortunately not physically hurt in the incident but it could have been afr worse if I had a vehicle in my front or on the lvd when the incident happened.
VIN: [redacted] I had an accident driving my Tesla model 3 on July 16th. Here is what happened: Driving autopilot at highway speed at ~65 mph Stray wheel/tire came and hit the front center hood/bumper of the car headon The hood flipped open tearing the hinges/struts on both sides of hood; hood lay flat on the front windshield With hood laying flat covering the whole windshield, front visibility became ZERO, also covering front windshield cameras Airbags popped on driver side (steering and below steering), and DEFLATED right away Autopilot did NOT disengage even after airbags deflated; car continued to drive ~65 mph on autopilot Not been able to see anything in the front, with both airbags deflated, and car still on autopilot at ~65mph, I found myself in a very life-threatening situation Eventually pulled the car to the shoulder on the left after changing one lane (still not been able to …
The car brakes by it and accelerates by it. Some time it says I am not holding the steering wheel and it cancels the autopilot in the middle of the long distance driving. The defective cabin camera does not see the hand position at all and randomly keeps on distracting from the front road view to the screen which is not in the same line as the road. Too many errors of auto pilot are very frustrating and distracting. The Tesla's team tries to repair something and keeps on blaming their own departments not to fix things correctly. I have tried many times to make an appointment thru their app which is very buggy and it's like one way communication. I have multiple recalls on my car but they don't have time or parts to fix it. They will not allow making any weekend or within 20 mile radius service center. …
NHTSA investigations
Sudden Unintended Acceleration
The Office of Defects Investigation (ODI) received a petition requesting that ODI reevaluate its decision to deny DP20-001 on the basis that intermittent high electrical current demands on the vehicles' 12VDC systems may have caused some or all of the incidents examined by ODI in DP20-001. The petitioner bases this information on a review of open-source research and the DP20-001 denial.
