2020 Tesla Model S Reliability Report

Owners of the 2020 Tesla Model S frequently report issues with the steering system, often describing a loss of power steering and associated electronic features like cruise control and lane departure warnings. Common symptoms include error messages indicating reduced steering assistance, loud squeaking or knocking noises, and instances where the steering wheel locks or becomes immobile. Problems often arise around 40,000 to 62,000 miles, with several reports involving crashes and three injuries. Additionally, multiple complaints highlight recurring issues with the suspension and steering components, such as ball joint failures and excessive vibration during acceleration, affecting vehicle control. These patterns suggest potential safety risks that used car buyers should consider.

Owners report several issues with the 2020 Tesla Model S electrical system, with frequent complaints about software and infotainment failures. Common symptoms include screens freezing or going dark, resulting in loss of speedometer and control over essential functions like blinkers and door locks. These issues often occur while driving, with some complaints noting occurrences around 50,000 to 77,000 miles. Safety implications are significant, as seven complaints involve crashes, and three report injuries. Additionally, reports of unintended acceleration and failure of self-driving features highlight potential risks, especially during high-speed travel. This information is crucial for prospective buyers to consider when evaluating the reliability and safety of this model.

Owners report several recurring issues with the 2020 Tesla Model S related to vehicle speed control. A common problem involves sudden unintended acceleration, with multiple reports of the vehicle accelerating on its own, often leading to crashes. Another frequently mentioned issue is phantom braking, where the vehicle abruptly decelerates without any apparent cause, sometimes nearly causing rear-end collisions. These problems are noted across various mileage ranges and often occur during routine driving or when using cruise control features. Safety implications are significant, as 17 complaints involve crashes and 10 injuries are reported. This information is critical for potential buyers considering the vehicle's history of speed control issues.

Owners report frequent issues with phantom braking in the 2020 Tesla Model-S, particularly when using cruise control or autopilot features. Complaints describe sudden, unexpected braking without any apparent obstacles, often at highway speeds, leading to potential safety hazards due to abrupt deceleration. Several incidents involve phantom braking occurring multiple times during a single trip, with some reports mentioning software updates as a factor influencing the frequency of these events. Additionally, there are instances of brake component wear, such as leaking brake hoses and missing caliper nuts, though these are less commonly reported than phantom braking. Safety implications include at least one crash and four injuries, highlighting the potential risks associated with these issues.

Owners of the 2020 Tesla Model S frequently report issues with door mechanisms, particularly the rear passenger doors lacking easily accessible emergency release handles, which could lead to entrapment if power is lost. Complaints also describe problems with the front hood unexpectedly opening while driving, obstructing vision and potentially leading to accidents. Several reports involve sudden unintended acceleration, resulting in crashes at low mileage. Safety implications are significant, with five crashes and one injury mentioned among the complaints. Buyers should be aware of these structural issues, especially concerning door accessibility and hood latching mechanisms, when considering this model.

Owners report recurring issues with the airbag system in the 2020 Tesla Model S, particularly involving the front passenger safety restraint system fault. Complaints frequently mention error messages like "RCM2_a626" and "RCM2_a636," which often lead to the airbag warning light illuminating and the system being disabled. Multiple owners describe airbag non-deployment during crashes, with several noting injuries as a result. These issues appear at varying mileages, with some reports starting as early as 14,000 miles. Safety implications are significant, with 10 crashes and 9 injuries reported, highlighting concerns about airbag reliability and potential malfunctions during accidents.

Owners of the 2020 Tesla Model S frequently report issues related to unintended acceleration and power train malfunctions. Common symptoms include unexpected surges when attempting to park, as well as vehicles going into neutral or reverse unexpectedly at highway speeds, with some incidents leading to crashes. Complaints also mention persistent vibrations and shuddering due to CV axle failures, often recurring after repairs. These issues are noted at various mileage ranges, with some occurring as early as 1,300 miles. Safety implications are significant, with multiple reports of crashes and loss of control, particularly during parking maneuvers or when disengaging cruise control.
