NHTSA lists 22 safety recalls and 674 owner complaints for the 2021 Tesla Model 3. Most complaints involve forward collision avoidance (411) and service brakes (126). The EPA rates it 113–142 mpg combined, and NHTSA gives it 5 stars overall.
Tesla, Inc. (Tesla) is recalling certain 2017-2023 Model 3 and 2020-2023 Model Y vehicles. The headlight low beams may be too bright and exceed the maximum light output. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Tesla, Inc. (Tesla) is recalling certain 2017, 2021-2023 Model 3, 2020-2023 Model Y, 2021-2023 Model S, and Model X vehicles operating software version 2026.8.6. The rearview camera image may be delayed when the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
Tesla, Inc. (Tesla) is recalling certain 2024 Cybertruck, 2017-2025 Model 3, and 2020-2025 Model Y vehicles. The tire pressure monitoring system (TPMS) warning light may not remain illuminated between drive cycles, failing to warn the driver of low tire pressure. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 138, "Tire Pressure Monitoring Systems."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Immediately following the installation of over-the-air software version 2026.32.3, the vehicle's center touchscreen lost all driving visualization capabilities. The backup camera now displays a black/non-responsive screen, removing federally mandated back-over protection. Additionally, the vehicle no longer provides active safety alerts, such as forward collision warnings or blind-spot obstructions, and driver-assist technologies (Autopilot) are entirely unavailable. Official Manufacturer Diagnosis: A physical diagnostic review of the vehicle's alert and signal history by Tesla Service confirmed an internal hardware communication failure directly induced by the software rollout. The official service logs state that the secondary Autopilot processor, designated as "Processor Turbo-B," has suffered a fatal fault and is failing to communicate. Tesla documentation acknowledges that this software-induced hardware lockup prevents the car from completing future software updates and has permanently disabled the safety vision suites. Current Vehicle Status: A subsequent physical replacement of the 12V low-voltage battery failed to resolve or clear the faults, confirming…”
“Urgent Safety Concern — Uncommanded Braking During Manual Driving. On October 2, 2026, while driving my 2021 Tesla Model 3 Standard Range manually at approximately 45 mph and slowing to make a turn at an intersection, my vehicle unexpectedly applied very strong braking for approximately 1–2 seconds before releasing. Neither Autopilot, FSD, nor Traffic-Aware Cruise Control was engaged. I am concerned about a possible unintended Automatic Emergency Braking activation or braking-system malfunction. This creates a serious safety concern for my family, including our newborn child. I request that this be urgently reviewed and determine what triggered the braking, including whether AEB, ABS, or another braking-control system intervened in suck similar cases, so many were reported online. Please also provide the diagnostic findings and a written assessment of whether the vehicle is safe to operate.”
“The forward-facing camera and Autopilot computer system on my 2021 Tesla Model 3 has failed. The dashboard first showed intermittent warnings that "Automatic Emergency Braking is currently unavailable" and "Adaptive headlight features are unavailable." Over several weeks the problem worsened from intermittent to constant, and the vehicle progressively lost its forward road visualization and all active safety features. Using the vehicle's Service Mode diagnostics, the Autopilot computer's Primary (A) processing node reports a "CRITICAL" status. The fault log records repeated alerts including dasMIA (driver-assistance system not responding), aebFault (automatic emergency braking fault), and fisheyeCamInitFault and fisheyeCameraStreamExit (forward camera initialization and stream failures). The cameras themselves are physically clean and unobstructed. Safety risk: the failure disables Automatic Emergency Braking and forward collision avoidance, lane-keeping/driver assistance, and the adaptive auto high-beam headlights. AEB is a critical crash-avoidance system; losing it leaves the vehicle unable to brake automatically for an imminent collision, and the loss of…”
