Recalls and investigations

One recall on collision avoidance covers the 2022 model year. A recall on the same system isn't always the same failure, so read the defect text.

Forward Collision Avoidance: Warnings:External/Pedestrian Alert

Tesla, Inc. (Tesla) is recalling certain 2013, 2018-2021 Model S, 2020-2021 Model X, 2018-2022 Model 3, and 2020-2022 Model Y vehicles. A factory reset muted the Pedestrian Warning System (PWS) sounds. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 141, "Minimum Sound Requirements for Hybrid and Electric Vehicles."

Risk and remedy
Risk: Pedestrians may be unaware of an approaching vehicle if the PWS sounds are muted, increasing the risk of a crash.
Remedy: Tesla released an over-the-air (OTA) software update, release 2023.44.30.14, free of charge. Owner notification letters were mailed April 27, 2024. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-24-00-006.

NHTSA investigations into collision avoidance on the Model 3

DP23-002opened Jun 29, 2023
Speed control · model years 2017 to 2023

Sudden unintended acceleration. Open.

NHTSA summary
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. The petition and related materials can be reviewed at NHTSA.gov under the following ODI number: 11528471.
PE22-002opened Feb 16, 2022
Collision avoidance · model years 2018 to 2024

Unexpected brake activation. Closed jun 29, 2026.

NHTSA summary
On February 16, 2022, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE22002) to investigate reports of unexpected deceleration while driving with the adaptive cruise control system engaged in Model Year (MY) 2021 – 2022 Model 3 and Model Y vehicles manufactured by Tesla. The subject systems include Autopilot (all versions), Full Self-Driving (FSD) and Traffic Aware Cruise Control (TACC). These complaints have been colloquially referred to as “phantom braking”. ODI opened PE22002 to determine the scope and severity of the potential problem and to assess any resulting safety issues in the subject vehicles. The alleged defect is an unexpected and unrequested vehicle deceleration triggered by the subject system during subject system engagement. The alleged defect does not occur when the subject system is not in use and is separate and distinct from Automated Emergency Braking (AEB). During vehicle operation, AEB is actively monitoring in the subject vehicles regardless of subject system and its intervention is accompanied by audible and visual collision warnings. A Vehicle Owners Questionnaire (VOQ) trend originating in November 2021 prompted ODI to open PE22002. VOQ narratives reported unexpected brake activation while using TACC, Autopilot or FSD. The trend grew from 99 by the end of 2021 to 314 by February 16, 2022, when PE22002 was opened. ODI sent Information Request (IR) Letters to Tesla on May 4, 2022, and July 11, 2024, to request salien

What owners wrote

“Experiencing phantom braking at high speeds when there is nothing there. This has happen 5-6 times during a recent road trip of 1000 miles”

“I was driving on a two lane road using auto pilot. I was going 55mph when all of a sudden my car slammed on the brakes down to 32mph as a school bus approached us. There was no reason to brake. The school bus never entered my lane. If a car had been following me closely I would have been rear ended for a system malfunction. Very scary.”

“Vehicle frequently brakes hard to prevent a collision with an object that does not exist. Also known as phantom breaking that is a commonly known issues with Teslas autopilot.”

Filed Feb 3, 2022

“Phantom braking is real. The car slams on brakes randomly while in cruise control. So much so that I will not use cruise control when another car is behind me.”

Should you keep driving it?

This page can't tell you that. 4 of 341 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
