2020 Tesla Model X Reliability Report

Owners of the 2020 Tesla Model X frequently report issues with sudden unintended acceleration and abrupt deceleration, often while using the vehicle's Autopilot or adaptive cruise control features. Complaints commonly describe the vehicle accelerating independently, even from a complete stop, leading to several crashes, including incidents where the vehicle hit other cars or stationary objects. Abrupt deceleration, often referred to as "phantom braking," is also noted, occurring at various speeds and sometimes causing near-miss rear-end collisions. These issues are reported across a range of mileages, with some incidents occurring in vehicles with less than 10,000 miles. Safety implications are significant, with seven reported crashes and two injuries, highlighting potential risks for used car buyers considering this model.

Owners of the 2020 Tesla Model X frequently report issues related to software and display systems. Multiple complaints describe problems with the instrument cluster and center screen, including instances where the display shows incorrect speed or goes completely black, particularly when using Full Self-Driving (FSD) features. Some owners note that these issues began following specific software updates. Additionally, there are reports of the vehicle abruptly braking without cause when on autopilot, and instances of unintended acceleration leading to crashes, one of which resulted in injury. The mileage at which these issues occur is not consistently reported, but some complaints arise shortly after software updates. These problems present significant safety implications, including loss of visual feedback and control, which may concern potential buyers.

Owners of the 2020 Tesla Model X frequently report issues with phantom braking when using autopilot, adaptive cruise control, or other driver assistance features. Typical symptoms include sudden, aggressive braking for no apparent reason, often reducing speed by 10-15 mph, especially on open highways or when approaching rises in the road. Complaints often mention this occurring at varying mileages, with some reports from as early as 10,000 miles and others around 50,000 miles. One report involved a crash due to sudden acceleration, while others describe near-miss situations where unexpected braking nearly caused accidents. Used car buyers should be aware of these potential safety implications, particularly if the vehicle has a history of using these driver assistance systems frequently.

Owners of the 2020 Tesla Model X report issues with unexpected acceleration, abnormal noises, and accelerator pedal failure. One incident involves the vehicle unexpectedly accelerating while parking, resulting in a crash into a retaining wall. Another owner describes a continuous grinding and whining noise while driving, attributed to a faulty front-end half-shaft at approximately 46,000 miles. Additionally, an owner reports the accelerator pedal breaking off while driving uphill, rendering the vehicle undrivable and necessitating towing. These complaints highlight potential safety concerns, including the risk of crashes and loss of vehicle control.

Owners report that the 2020 Tesla Model X experiences unexpected aggressive braking when cruise control is engaged. This issue occurs without any apparent obstacles or vehicles in proximity, primarily at highway speeds around 70-75 MPH. Complaints frequently mention that these braking incidents have happened multiple times over several months, with some owners noting similar issues in other Tesla models. While no crashes or loss of control are reported, the sudden braking is described as a potential safety concern due to the risk of rear-end collisions. Prospective buyers should be aware of these repeated braking complaints, particularly when considering long highway drives.

Owners of the 2020 Tesla Model X report issues with rear tire wear, specifically noting extreme inner rim wear that exposes the steel belt. Complaints frequently mention uneven tread wear, with the inner part of the rear tires wearing significantly faster than the outer part. These issues are observed at relatively low mileages, around 6,300 miles. Symptoms include flat tires and metal-sounding noises, particularly noticeable when driving over road markers. Safety implications are highlighted as owners express concern over the potential risk of tire failure, especially at highway speeds.

Owners report issues with the back over prevention systems in the 2020 Tesla Model-X, including sudden unintended acceleration and malfunctioning rear view cameras. One complaint describes the vehicle accelerating unexpectedly while idling, resulting in a crash and injury, with the emergency braking system failing to engage. Another complaint highlights the rear view camera freezing, which can lead to near misses, particularly in low visibility areas. These issues present safety implications, such as loss of control and potential collisions, which are critical for prospective buyers to consider.
