2019 Tesla Model 3 Reliability Score & Common Problems

Owners of the 2019 Tesla Model 3 frequently report issues with the suspension, particularly involving the failure of control arms and lateral links. Symptoms commonly described include abnormal noises such as squeaking or clunking, instability in handling, and in some cases, the complete separation of suspension components. These issues often arise between 30,000 to 50,000 miles, with some owners noting failures even earlier. Safety implications are significant, with several reports of crashes and loss of vehicle control due to suspension failures. Prospective buyers should be aware of these recurring issues and the potential for costly repairs, as some vehicles are not covered by existing recalls despite experiencing similar failures.

Owners report frequent issues with the 2019 Tesla Model 3's airbag and safety restraint systems, particularly involving error codes like RCM_a056 and RCM_a021. Complaints frequently mention faults with the front passenger safety restraint system, often linked to wiring problems under the seats or malfunctioning sensors, which may disable airbag deployment. These issues typically appear around 35,000 to 50,000 miles, with some owners noting repeated occurrences even after repairs. Safety implications are significant, with reports of eight crashes and five injuries potentially related to these faults. Used car buyers should be aware that repairs can be costly, with estimates ranging from $300 to over $2,000, and that these faults may recur.

Owners of the 2019 Tesla Model 3 frequently report issues with the steering system, particularly involving water ingress leading to corrosion in the steering rack and wiring harness. Symptoms commonly described include error messages indicating "Steering assist reduced" and complete power steering failure, often requiring significant effort to steer, especially at low speeds or during turns. Many complaints mention these problems occurring around 29,000 to 93,000 miles. Safety implications are evident, with reports of steering lock-up while driving, leading to five crashes and four injuries. Additionally, some owners experience issues with the front suspension, including torn control arm bushings and lateral link failures, contributing to instability and increased risk of losing control. This data suggests potential concerns for used car buyers regarding steering reliability and associated safety risks.

Owners of the 2019 Tesla Model 3 frequently report issues with the Full Self Driving (FSD) system, including phantom braking, unexpected lane changes, and failure to recognize traffic control devices. Complaints often describe sudden and dangerous braking, unintended acceleration, and the vehicle's inability to navigate intersections safely. These issues are reported across various mileage ranges, with some owners experiencing problems shortly after software updates. Safety implications are significant, as reports include crashes, one fire, and an injury, highlighting potential risks of loss of control. Additionally, owners mention software-related concerns such as display malfunctions and climate control interface issues, which may affect vehicle usability.

Owners of the 2019 Tesla Model 3 frequently report issues with "phantom braking," where the vehicle unexpectedly brakes or decelerates, especially when using cruise control or autopilot. This occurs at highway speeds and can happen multiple times during a single trip, often without any apparent reason or nearby obstacles. Complaints also highlight instances of brake failure, including rust or corrosion of brake lines, leading to fluid leaks and potential loss of braking capability. Some reports involve crashes, with instances of the brakes failing to engage or the car accelerating instead of stopping. These issues are noted across various mileages, and the safety implications include potential rear-end collisions and loss of vehicle control, which are significant considerations for prospective buyers.

Owners of the 2019 Tesla Model 3 frequently report issues with the Full Self-Driving (FSD) system's lane departure functionality. Common symptoms include the vehicle veering into adjacent lanes or bike lanes, failing to correctly interpret road markings, and making incorrect lane changes, often requiring driver intervention to prevent potential collisions. A specific incident involved a crash during inclement weather, resulting in an injury when the lane departure feature malfunctioned. These issues are often reported at varying speeds and under different driving conditions, with some complaints noting problems at around 66,000 miles. Safety concerns are highlighted by the risk of collisions with other vehicles or cyclists, particularly in scenarios where FSD misjudges lane boundaries.

Owners report several issues with the 2019 Tesla Model 3's power train, with frequent mentions of sudden loss of motive power while driving, sometimes accompanied by messages like "Vehicle Hold Disabled" or "Power Reduced". These incidents typically occur around 34,000 miles and can lead to situations where the vehicle needs to be towed. Another common problem involves the car unexpectedly accelerating or not shifting correctly between drive and reverse, with one instance resulting in a crash during parking. Additionally, complaints highlight potential design flaws in the battery pack coolant connector, leading to coolant leaks and reduced power without adequate warning. Safety concerns arise from these issues, including loss of control and inability to safely move the vehicle, which prospective buyers should consider.
