2023 Tesla Model 3 Problems: 11 Known Issues

On the 2019-2024 Tesla Model 3 all, model 3 and Y on Autopilot or TACC report unexpected hard braking events — "phantom braking" — most often at highway speed in response to non-existent obstacles, shadows, overpasses, or oncoming traffic in opposite lanes. NHTSA investigation PE22-002 opened in February 2022 covering an estimated 416,000 2021-2022 Model 3 and Model Y vehicles after 354 complaints; NHTSA identified no collisions or injuries. Tesla's shift from radar to "Tesla Vision" (vision-only) intensified reports.

On the 2023 Tesla Model 3, on certain 2023 Model 3/Y cars, the electronic power-assisted steering (EPAS) printed circuit board can become overstressed during low-speed maneuvering, causing loss of power steering assist when the car stops and accelerates again. Drivers must apply much greater steering effort, raising crash risk. Tesla recalled ~376,000-380,000 vehicles.

On the 2017-2024 Tesla Model 3, model 3 owners widely report tires wearing out on the inner edge well before expected mileage. Causes are factory negative camber (for handling), toe misalignment, high instant torque, and overinflation; only toe is adjustable from the factory (camber is fixed unless aftermarket arms are added). Some Service Centers call it 'normal Tesla wear,' frustrating owners since a basic alignment often doesn't fully cure it.

On the 2017-2023 Tesla Model 3, a very common Model 3 (and Model Y) complaint is a squeaking or dry-hinge/creaking noise from the front suspension at low speed and over bumps, traced to the front upper control arm (FUCA) ball joint. Water bypasses the ball-joint seal, washing out the grease and allowing metal-on-metal corrosion. The noise is often reproducible by opening the frunk and pushing down on the front of the car. Tesla frequently replaces the arms under warranty and has covered labor as 'goodwill' even on some out-of-warranty cars.

On the 2017-2024 Tesla Model 3, around 40,000-70,000 miles many Model 3/Y owners report a clunk, pop or knock from the front end over bumps, under braking or acceleration. The cause is torn rubber bushings in the front lower lateral link (front lower control arm) and compliance/fore-aft link. When the bushing rubber tears, the arm develops play on its bolt and metal parts contact, producing the clunk. A clunk combined with steering wander is a safety concern.

On the 2017-2024 Tesla Model 3, the backup camera image can fail to display when shifting to reverse. Two documented root causes: (1) on certain Model 3 cars built Jan 15 - Dec 12, 2024 with specific car computers, a software power-up sequence could short the computer's power components, especially in cold weather, addressed by NHTSA recall 25V-002, and (2) mechanical wear of the coaxial camera cable routed through the trunk-lid harness, which frays after repeated trunk opening/closing and cuts the video feed. Loss of the reversing image is a safety/visibility concern.

On the 2017-2024 Tesla Model 3, early Model 3 and Model Y (built before the late-2021 switch) used a small lead-acid AGM 12V auxiliary battery that often fails in 12-24 months — well below typical 12V lifespan. Tesla switched to a lithium-ion 12V starting 2021-2022 (varies by build date) which lasts much longer but can also fail with "Power Off" warnings or refusing to wake. Symptoms: "12V Battery Needs Service" alert, car refusing to wake from sleep, sentry mode glitches.

On the 2017-2024 Tesla Model 3, the high-voltage battery slowly loses charge while parked because background systems stay awake. Normal drain is under ~1%/day, but owners report much higher losses (several percent per day) when Sentry Mode, Cabin Overheat Protection, Summon Standby, Dog/Camp mode, or third-party apps repeatedly wake the car and prevent it from sleeping.

On the 2017-2023 Tesla Model 3, in snow/ice, moisture inside the flush pivoting door handle freezes and the handle will not depress/deploy, locking owners out. Tesla's own owner's manual acknowledges ice buildup can prevent the handle from opening. Forcing a frozen handle can damage the internal mechanism, and handle replacement runs $300-600+.

On the 2017-2024 Tesla Model 3 all, tesla paint has been measured thinner than typical — a 2019 Finnish inspection of one Model 3 found a 106-micron average (low-70s on the lower doors) vs the 110-150 microns cited as standard, with softer-than-usual clearcoat. Rocker panels, rear quarter panels, and front bumper edges chip easily from road debris. White paints are particularly prone to surface marring. Multiple paint-quality NHTSA complaints (no recall) and class-action discussions.

On the 2017-2024 Tesla Model 3, in cold, humid conditions the windshield and side glass can fog rapidly (sometimes within ~30 seconds) when recirculation is on, because humid cabin air is retained instead of exhausted. Some owners feel the heat-pump-equipped cars dehumidify less aggressively than the older resistive A/C setup. It is largely an HVAC-mode/behavior issue rather than a defect, but it is a frequent and safety-relevant complaint.
