Mar 31, 2026AirbagsDriver assistanceCrash

The components involved are the automatic emergency braking (AEB) system and the airbag system. During the collision, the AEB system did not activate, and the airbags did not deploy. The vehicle is available for inspection upon request. I was driving on a main roadway with no stop signs or traffic controls in my direction when another driver entered from a side street with a stop sign and pulled directly in front of me. I was unable to avoid the collision, and my vehicle was struck the other vehicle. The failure of the AEB system to engage and the airbags not deploying increased the risk of injury to myself and could have posed a risk to others involved. The issue has not been reproduced, and it has not yet been confirmed by a dealer or independent service center. The vehicle has been inspected by police and insurance representatives. The other driver was determined to be at fault. I am in the process of addressing the incident with the manufacturer. There were no warning lights, messages, or prior symptoms indicating any issue with the braking or airbag systems before the collision.

I drove into my neighbor’s driveway to drop her off. As I slowed down and applied the brakes to stop, the car failed to respond. It continued forward, running over the flower and plant pots at the edge of the driveway, crossing the backyard, and finally colliding with the trees and bushes at the rear of the property. All airbags deployed, and the vehicle was damaged beyond repair.

Component/System involved: Advanced Driver Assistance Systems — FSD (Supervised)/Autosteer (Lane Keeping Assistance) and Adaptive Cruise Control. Possible failure to warn/stop (FCW/AEB). Vehicle and data are available for inspection upon request. I preserved dashcam files and requested Tesla to preserve engineering logs and EDR. What happened & safety risk: On [XXX] at ~[XXX] PDT on [XXX] near East Palo Alto, CA, with FSD (Supervised) engaged, the system appeared to misinterpret an exit ramp/gore area as a continuing lane at a highway fork and maintained ~60 mph (posted ~70). As soon as I saw the trajectory was unsafe, I braked and began manual steering takeover, but the vehicle contacted a roadside sign near the gore/shoulder before I could complete the maneuver. I then stopped safely. No other vehicles were struck. Airbags did not deploy. This posed a serious collision risk to me, my passenger, and nearby traffic. Reproduction/confirmation: NOT REPRODUCED. I have not attempted to reproduce the event. UNKNOWN whether the issue has been reproduced by Tesla or a service center yet. Inspection to date: Police responded (report pending). My insurer has opened a claim. I opened a Tesla Service request asking to PRESERVE Autopilot/FSD engineering logs for the incident window and to coordinate EDR extraction; engineering review pending. Vehicle remains drivable. Warnings or symptoms before failure: No audible/visual forward-collision warning was perceived by me and I did not observe automatic emergency braking. No prior warning lamps/messages were noticed before the departure toward the gore. UNKNOWN whether any internal/partial interventions were recorded in logs. Evidence available: Four-camera Tesla dashcam footage saved and backed up (see [XXX] ); precise time window ~[XXX] PDT on [XXX]. I can provide files and cooperate with data retrieval/inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [Wednesday, 07/09/2025], I was driving my Tesla Model 3 in rainy conditions when the vehicle suddenly swerved and crashed into a sidewall. The road was wet but not flooded, and I was traveling at a moderate speed. As I lifted my foot off the accelerator to slow down, the car's regenerative braking system engaged abruptly, which I believe shifted weight forward and caused the rear tires to lose traction. This led to hydroplaning and complete loss of control. There were no warning lights or alerts prior to the incident. The road surface did not have visible hazards or standing water that would typically explain a spinout. The tires were moderately worn but within usable limits. As a result of the crash, the car was declared a total loss. The insurance company now has possession of the vehicle. Thankfully, no one was injured, but the crash was severe. After the incident, I researched similar cases and found multiple reports and articles (e.g., AutoEvolution) linking Tesla’s regenerative braking to increased risk of hydroplaning or loss of control in wet or slippery conditions. The regen system eliminates coasting and applies braking force immediately upon throttle lift-off, which appears to be a safety risk in reduced-traction environments like rain, snow, or ice. I believe this issue deserves investigation, as it may affect the safety of other Tesla drivers in similar weather conditions.

Trip from Piedmont, California to Salt Lake City, Utah, I experienced three (x3) phantom breaking incidents at over 80 mph on interstate 1-80. The car without warning dramatically de-accelerated from approximately 85mph to 65mph or 60mph without warning and suddenly. Dog was riding in back and thrown into front dashboard on one occasion. Visited Tesla dealership on State St in Salt Lake City Utah upon destination arrival and manager/head at front desk laughed indicents off saying, "we've heard of such incidents just wait for the software update." Horrible. Beyond dangerous. I can report that in all three incidents there were no cars in front or behind me and the phenonenon occurred totally unexpectedly. Reported it also to Tesla repair shop in Berkeley, California, and intake group had zero sympathy and said, "it's a known software glitch."

I was driving SB on N Gate Rd in Vacaville, approaching the gate for Travis AFB. There was traffic backed up at the gate and I put the car into Autopilot to negotiate the stop and go traffic. I had been in Autopilot for maybe 50 yards when the car suddenly accelerated on it's own and veered to the right. The brakes would not work to stop the car and the steering wheel would physically turn but it wasn't changing the direction of the car. The car veered off the road to the right and into a utility pole.

The car was on FSD jerked right toward a semi truck then jerked left toward the posts in the median as it was accelerating and FSD would not turn off. Was trying to control the car but it kept pushing and accelerating causing us to crash in to the median posts. Normally FSD would turn off if it was unsure but this day it would not. Plus other times it would phantom brake if we were on 2 lane road and met on oncoming large truck. We also had other times of phantom braking going over a hill. We have reported this to Tesla but no response yet. We owned this car 11 days when our wreck happened.

Forward Collision Warning and Automatic Emergency Braking system failed/malfunctioned. The car is in a Tesla authorized body shop for inspection. The airbag deployed and prevented any injury but the accident did put my life and others at risk. The car was inspected by Tesla's authorized body shop. There was no warning lamps, messages, or other symptoms of the problem prior to the failure. The car was brand new, and I believe a possible explanation is Tesla taking out the radar and replacing it with Tesla vision. I tried to contact Tesla for an investigation but no response. I received a 30k bill to fix the car, and Tesla did not take any responsibility. Here is the footage: https://www.dropbox.com/s/sat1w5i0gl6bwsr/2021-12-20_10-56-45-front.mp4?dl=0

Phantom braking for no apparent reason. Worst occurrence was this morning driving home from work on cruise control, max speed cruise 73mph, suddenly my car braked on its own down to 59mph in 2 seconds. Very scary. My wrist hurts from that incident & my forehead almost hit the steering. Nothing in front & thank God no tailgating car behind me. This is not safe. It happens to me all the time but this was the scariest of all.

Hello, Driving on a snowy road around 20 MPH. Attempted to slow down in a straight line, used the brakes to try and slow vehicle to go into a driveway. Vehicle would not respond to any inputs. The brake pedal seemed frozen, coming off and back on the brake pedal did not change anything. There sounded like an ABS pulsing but it was not working. Post accident pictures showed it looked like the car was dragging one axle like it was locked in the snow. Car ending up grazing a mailbox post and afterword said 'take control'. I believe the car tried to do an automated braking maneuver which did not work. The road was covered in 1-2" of snow and the mailbox would have been a reference point in the distance. When turning the steering wheel away from the object that was hit, the car continued to go straight like the wheels were not attached. The car never veered left or right during this whole event even though i tried to turn.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Tesla Model 3 Bev verdict →
