Recalls for the 2021 Tesla Model Y: 23
The headlight low beams may be too bright and exceed the maximum light output. Headlight low beams that are too bright can reduce visibility for oncoming drivers, increasing the risk of a crash.
The rearview camera image may be delayed when the vehicle is placed in reverse. A delayed rearview image reduces the driver's view behind the vehicle, increasing the risk of a crash.
The tire pressure monitoring system (TPMS) warning light may not remain illuminated between drive cycles, failing to warn the driver of low tire pressure. Driving with improperly inflated tires increases the risk of a crash.
The hood latch assembly may fail to detect an unlatched hood condition after the hood has been opened. An unlatched hood can fully open, obstructing the driver's view and increasing the risk of a crash.
In the event of an unbelted driver, the seat belt warning light and audible chime may not activate as intended. A seat belt warning system that fails to alert occupants of an unbelted seat belt can increase the risk of injury during a crash.
A factory reset muted the Pedestrian Warning System (PWS) sounds. Pedestrians may be unaware of an approaching vehicle if the PWS sounds are muted, increasing the risk of a crash.
An incorrect font size is displayed on the instrument panel for the Brake, Park, and Antilock Brake System (ABS) warning lights. Warning lights with a smaller font size can make critical safety information on the instrument panel difficult to read, increasing the risk of a crash.
In certain circumstances when Autosteer is engaged, the prominence and scope of the feature's controls may not be sufficient to prevent driver misuse of the SAE Level 2 advanced driver-assistance feature. In certain circumstances when Autosteer is engaged, and the driver does not maintain responsibility for vehicle operation and is unprepared to intervene as necessary or fails to recognize when Autosteer is canceled or not engaged…
The FSD Beta system may allow the vehicle to act unsafe around intersections, such as traveling straight through an intersection while in a turn-only lane, entering a stop sign-controlled intersection without coming to a complete stop… FSD Beta software that allows a vehicle to exceed speed limits or travel through intersections in an unlawful or unpredictable manner increases the risk of a crash.
One or both taillights may intermittently fail to illuminate. A taillight that fails to illuminate may reduce the visibility of the vehicle, increasing the risk of a crash.
The window automatic reversal system may not react correctly after detecting an obstruction. A closing window may exert excessive force by pinching a driver or passenger before retracting, increasing the risk of injury.
The fisheye and narrow camera cable terminals were incorrectly installed in the cable harness connector, resulting in swapped camera views. Swapped camera views can prevent the vehicle's cameras from detecting crossing objects and high-curvature lane lines, impairing the Autosteer and Automatic Emergency Braking (AEB) performance, and increasing the risk of a crash.
The Boombox function allows sounds to be played through an external speaker while the vehicle is in motion, which may obscure the Pedestrian Warning System (PWS) sounds. Pedestrians may be unaware of an approaching vehicle if the PWS sounds are obscured, increasing the risk of a crash.
The Boombox function allows sounds to be played through an external speaker while the vehicle is in motion, which may obscure the Pedestrian Warning System (PWS) sounds. Pedestrians may be unaware of an approaching vehicle if the PWS sounds are obscured, increasing the risk of a crash.
A software error may cause a valve in the heat pump to open unintentionally and trap the refrigerant inside the evaporator, resulting in decreased defrosting performance. Decreased defrosting performance may reduce the driver's visibility, increasing the risk of a crash.
The audible chime may not activate when the vehicle starts and the driver has not buckled their seat belt. The driver may be unaware that their seat belt is not fastened, increasing the risk of injury during a crash.
The "rolling stop" functionality available as part of the Full Self-Driving (Beta) software may allow the vehicle to travel through an all-way stop intersection without first coming to a stop. Failing to stop at a stop sign can increase the risk of a crash.
The front and rear suspension knuckles may fracture, causing the suspension links to separate. Suspension links that separate can reduce vehicle stability and control, increasing the risk of a crash.
A communication error may cause false forward-collision warning (FCW) or unexpected activation of the automatic emergency brake (AEB) system. Unexpected activation of the AEB system may cause the car to stop suddenly, increasing the risk of a crash.
The front suspension lateral link fasteners may loosen, allowing the lateral link to separate from the sub-frame. A lateral link separation could shift the wheel alignment, causing instability and increasing the risk of a crash.
One or both fasteners that secure the front seat shoulder belt to the b-pillar may not be properly attached. An improperly attached fastener may prevent the seat belt system from performing as designed, increasing the risk of injury.
One or both fasteners that secure the left and right second row seat belt retractors may not be properly attached. Improperly attached fasteners may prevent the seat belt retention system from performing as designed, increasing the risk of injury.
The brake caliper bolts may be loose, allowing the brake caliper to separate and contact the wheel rim. Contact with the rim may cause a loss of tire pressure, increasing the risk of a crash.

Method: counts of unverified owner complaints filed with NHTSA, compared only with other years of the same model (sales volumes are unknown, so no failure rate is computed). A system stands out at 40+ complaints and at least twice the model's quiet (lower-quartile) year, or twice the share across every vehicle of that model year. The mileage range is the 25th to 75th percentile of the mileages owners reported. Data received by NHTSA through November 5, 2026. Repair prices are typical US ranges from named sources, not quotes.
