2021 Tesla Model S Reliability Report

Owners report frequent issues with the electrical system in the 2021 Tesla Model S, particularly involving the instrument panel and computer system failures. Complaints frequently mention the screen going blank, which can disable essential functions such as speed display, turn signals, and driver assistance features. These issues often occur randomly but have been noted from as early as a few days after delivery and can persist despite software updates. Safety implications are significant, with multiple reports of crashes, one involving a fire, and several incidents where occupants were trapped due to door malfunctions. Mileage at the time of failure varies widely, but some owners experience problems by approximately 9,400 miles. This information is crucial for potential buyers to consider when evaluating the reliability and safety of this vehicle model.

Owners report several steering-related issues with the 2021 Tesla Model S, including steering lock-ups, heavy steering, and loss of steering assist, often accompanied by warning messages such as "steering assist reduced." Complaints frequently mention these problems occurring around 25,000 to 55,000 miles. Some owners describe situations where the steering becomes unresponsive or locks while driving, leading to loss of control, with 12 incidents resulting in crashes and six injuries reported. Additionally, issues with the steering yoke, such as peeling and horn button placement, are noted as potential safety concerns. These patterns suggest prospective buyers should be aware of potential steering system repairs and associated costs.

Owners report that the 2021 Tesla Model S frequently experiences "phantom braking" incidents, where the vehicle unexpectedly applies the brakes without any apparent obstacles, often during highway driving with adaptive cruise control or autopilot engaged. Typical symptoms include sudden deceleration from speeds of 65-80 mph to significantly lower speeds, sometimes as low as 35 mph, which can pose a risk of rear-end collisions. Although the mileage at which these incidents occur is not consistently reported, some owners note that the issue persists even after software updates. Among the 105 complaints, 7 involve crashes, and 1 injury is reported, highlighting potential safety implications. Prospective buyers should be aware of these braking anomalies and the potential for unexpected vehicle behavior.

Owners report frequent issues with the suspension system of the 2021 Tesla Model S, particularly involving the control arms and suspension links. Symptoms commonly described include premature tire wear, creaking or squeaking noises during low-speed maneuvers, and components separating or failing, often without warning lights. Complaints suggest these issues can manifest as early as 10,000 miles and continue to occur around 50,000 miles. Some reports involve crashes and one injury, indicating potential safety implications such as loss of steering control. Buyers should be aware of these recurring suspension problems and the associated repair costs, as they may not be covered under warranty.

Owners of the 2021 Tesla Model S frequently report issues related to the power train, including sudden loss of power and regenerative braking malfunctions. Symptoms often described include abrupt deceleration, unexpected propulsion, and intermittent drive disconnections, sometimes without warning lights or alerts. These issues have been reported to occur at various mileages, with some incidents leading to crashes and fires, highlighting potential safety risks. Additionally, multiple complaints mention problems with the vehicle's front half shafts and drive unit failures, often requiring repeated service visits without a definitive resolution. These patterns suggest potential reliability concerns for prospective buyers considering a used 2021 Tesla Model S.

Owners report two primary issues with the 2021 Tesla Model S airbag system: intermittent airbag deactivation for front seat passengers and recurring safety restraint system faults. Complaints frequently mention the passenger airbag failing to activate, especially for lighter passengers around 100-123 lbs, with status changes occurring during drives. Multiple owners describe persistent alerts for safety restraint system faults, often linked to occupant and impact sensors, which sometimes return even after service visits. Approximately five incidents involved crashes where airbags did not deploy, with some vehicles having mileage as low as 1,000 miles. These issues, particularly the lack of airbag deployment in crashes, suggest potential safety concerns for prospective buyers.

Owners of the 2021 Tesla Model S report issues primarily related to motor malfunctions. Complaints frequently mention sudden vehicle stalling or complete shutdowns, often accompanied by loud noises or thuds from the rear of the vehicle. One report involves a fire following a rear motor malfunction, where the vehicle initially indicated it was safe to drive before the incident occurred. These issues are noted to occur without prior warning, posing potential safety risks such as loss of control or inability to move the vehicle. The complaints do not specify exact mileage ranges, but the incidents are described as unexpected and potentially hazardous, particularly if they occur in traffic or at higher speeds.
