Tesla Model Y phantom braking problems

Filed Oct 23, 2026 · Driver assistance, Steering · TX · crash

On [XXX], between approximately [XXX] and [XXX] AM, I was driving my 2021 Tesla Model Y Long Range (VIN: [XXX]) with Full Self-Driving (Supervised) engaged, software version v14.3 Lite, on the southbound [XXX] frontage road at [XXX]. The road has five lanes in my direction, and only the leftmost lane is a left-turn lane. I was in the third lane from the left, and the navigation route required a left turn onto [XXX] at the upcoming intersection. FSD waited until the last moment to change lanes. The light turned red before it could complete the lane change, and the vehicle stopped straddling two lanes, still not in the left-turn lane. I expected FSD to continue straight and reroute. Instead, when the light turned green, the vehicle cut across the leftmost lane and drove up onto the median, apparently attempting to cross over it to complete the left turn. The other side of the median is oncoming traffic. There were two poles with city signs on the median, and the vehicle struck them. I took over immediately, but the collision had already occurred. No other vehicles or people were involved, and no one was injured. My vehicle sustained severe front-end damage, including a detached front bumper, a deformed left fender, and a shattered windshield. FSD/Autopilot features are no longer functioning. The vehicle did not automatically contact emergency services; I called the police myself. The incident was reported to the police (report #[XXX]) and to my insurance company, Progressive (claim #[XXX]). Tesla has contacted me to investigate. I have preserved the dashcam footage. Prior to this incident, I had also experienced repeated FSD issues after a software update in July 2026, including phantom braking and the vehicle suddenly stopping and freezing at intersections, requiring manual takeover.

The Autopilot/Active Safety sensor system and automated emergency braking (AEB) component failed. The vehicle experienced an uncommanded, severe "phantom braking" event and simultaneous steering lock. The vehicle is currently [State if it is at a tow yard, repair shop, or totaled, e.g., at an insurance-designated salvage yard] and is available for inspection upon request.

In the 5 years we have had this vehicle there have been multiple issues with the Self Driving feature including: 1)Phantom braking on busy freeways in [XXX] 2)Swerving randomly into the other late on a curve on 4 lane hwy at 65 mph ([XXX] near [XXX]) 3)Attempting to switch lanes into fast traffic when we were at a standstill in rush hour traffic ([XXX]) 4)Slamming brakes on on a 2 lane road on a curve because there was a semi in the other lane (that had not crossed the line) [XXX] 5)Being a short way from exiting the freeway and having the car jump back into traffic ([XXX] at [XXX]) 6) Slammed on brakes when the car in front of us was exiting [XXX] normally on an offramp going northbourd around the city of [XXX]. These are some of the most egregious errors the car has made, but there are more not listed. I try it on occasion when there is a software update. It is not safe though- almost without fail I need to take over each time I try it. As [XXX] said on XXX "Hardware 3 simply does not have the capability to achieve unsupervised FSD due to physical computing and memory limitations." The full self driving is dangerous, yet each time I get in the car the computer encourages its use. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2023 Tesla Model Y (VIN: [XXX]) equipped with Full Self-Driving and Hardware 3 (HW3) computer. Over the last couple of years, while using Autopilot/FSD, my vehicle has repeatedly exhibited phantom braking, including sometimes coming to a complete stop for no reason. My vehicle has also swerved into the lane of oncoming traffic on many occasions. On one occasion, this happened three separate times in one day, and the following day the vehicle swerved off the side of the road while FSD was engaged. I have reported these incidents to Tesla Service repeatedly for years, including photos of related screen malfunctions and "What Happened" incident data, documented in the Tesla app as well as in-person at service center visits. August 2026 was the first time Tesla told my husband and me that this was a known hardware/software (Hardware 3) issue, despite years of prior reports. Tesla has given conflicting information about whether a hardware upgrade is possible: I was told the HW3 computer cannot be upgraded and was encouraged to purchase a new vehicle instead, while a service representative separately mentioned a $3,000 upgrade option that "probably wouldn't fix the issue anyway." I am concerned this vehicle poses an ongoing risk of a head-on collision or road departure to myself and other drivers.

My chat constantly phantom brakes. This is a constant issue, I ve had the car since it was new and almost everytime im in adaptive cruise control it randomly brakes. Today with nothing in front of my on 3 separate occasions it applies the brakes and forces me to accelerate to maintain speed.

Phantom braking while using the TACC on the tesla

Filed Aug 17, 2026 · Driver assistance, Electrical · GA

On XXX, while driving southbound on XXX from [XXX] toward [XXX], my vehicle’s center display (MCU) crashed and rebooted at highway speed, leaving me with no screen for approximately 5–10 minutes. Sequence of events: 1.Earlier in the drive, while using Full Self-Driving (Supervised) v14 Lite, the vehicle exhibited phantom braking and speed oscillation (repeatedly cycling between approximately 73, 70, and 72 mph without cause). I disengaged FSD and switched to standard Autopilot. 2.During this portion of the drive, three alert codes appeared: UI_a111, APP_w207, and DI_a175 (the latter twice). 3.I stopped to Supercharge in [XXX] at 1:17 PM (33-minute session ending approximately 1:50 PM), then resumed driving on XXX [XXX]. 4.Shortly after resuming the drive, at approximately 1:53 PM, I tapped on one of the displayed alerts on the touchscreen to view details. The screen opened an in-car help/browser page, then the entire MCU crashed and went dark. 5.The display remained black for approximately 5–10 minutes while I was traveling at highway speed. During this time I had NO speedometer, NO navigation/GPS, NO touch controls, and NO visibility into vehicle alerts or state. In a Tesla Model Y, the center display is the ONLY instrument display — there is no separate gauge cluster. 6.The MCU eventually rebooted on its own and the display returned. The incident time is corroborated by a text message my wife sent me from inside the vehicle at 1:53 PM at my request, specifically to create a contemporaneous timestamped record. Safety concern: A driver-initiated tap on a safety alert — an action the interface invites — triggered a total display failure at highway speed. Loss of the sole speedometer and all vehicle status information while traveling at approximately 70+ mph is an unreasonable safety risk. This occurred on the same drive as continued phantom braking and speed oscillation events previously reported in ODI #XXX, o INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2026 Tesla Model Y. The contact stated that while driving at an undisclosed speed with the Full Self Driving Mode activated, the vehicle struck the garage wall, damaging the rear passenger’s side door. No injuries were sustained. The contact stated that the dealer had previously provided mobile service to replace the camera and that a second dealer, Tesla White Plains (250 Tarrytown Rd, White Plains, NY 10607), had performed a hard reset on the vehicle due to phantom braking; however, the failure persisted. The dealer was made aware of the failure but canceled an upcoming appointment and informed the contact that there was no failure found. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 13,001.

Our car phantom brakes when traveling through shadows frequently and occasionally at random. This occurs at high speed as well as low speed.

Separately, the system could not hold a consistent speed on open highway with no vehicle ahead. It would surge from a set 70 mph to roughly 72-73 mph and then drop back, repeatedly, producing a pulsing acceleration and deceleration. The system also hesitated frequently and issued repeated audible alerts without an identifiable hazard present. I previously filed a complaint regarding phantom braking on this same vehicle (ODI number 11450326, filed February 4, 2022), which described nearly identical behavior triggered by trucks on the same Georgia-to-New Jersey route. That complaint concerned FSD/Autopilot software from 2022. The behavior described here occurs on Tesla’s current v14 Lite software released to Hardware 3 vehicles in July 2026. The defect has persisted across more than four years and multiple software generations. Unexpected hard braking at highway speed with no hazard present creates a rear-end collision risk to my vehicle and to following traffic.
