2024 Tesla Model 3 Reliability Score & Common Problems

Owners of the 2024 Tesla Model 3 frequently report issues with the vehicle's forward collision avoidance systems, particularly involving phantom braking and improper operation of Full Self-Driving (FSD) features. Complaints commonly describe unexpected and abrupt braking, often without any apparent obstacles, and instances where the vehicle fails to recognize speed limits or traffic conditions, leading to unsafe accelerations or missed exits. Some owners mention problems with fogging of the forward-facing camera, affecting the functionality of safety systems like automatic emergency braking and lane keeping. One reported crash involved Autopilot making an unauthorized turn, resulting in injuries. These issues are noted across various driving conditions and do not appear to be limited to specific mileage ranges, suggesting potential concerns for safety and reliability for prospective buyers.

Owners report frequent issues with the 2024 Tesla Model 3's turn signal buttons, which are integrated into the steering wheel. Many describe these buttons as unreliable, often failing to activate, sticking, or not providing haptic feedback, particularly during maneuvers like lane changes or roundabouts. Some mention that the signals can activate the opposite direction or require excessive pressure. One incident involved a crash due to a complete exterior light failure while using full self-driving mode. These issues typically arise shortly after purchase, with some vehicles having as little as 1,800 miles. Additionally, a few owners experience water ingress in the rear tail light, affecting brake light functionality. These problems present potential safety risks, especially in situations requiring clear signaling to other drivers.

Owners report several recurring issues with the 2024 Tesla Model 3's vehicle speed control systems. A significant number of complaints describe the Full Self-Driving (FSD) software version 14.x removing driver control over maximum speed settings, leading to the vehicle exceeding speed limits by 5-20 mph without the ability to adjust, even in sensitive areas like school zones. Additionally, multiple owners mention sudden, unexpected deceleration events, often referred to as "phantom braking," where the vehicle rapidly slows down without clear cause, sometimes from speeds as high as 75 mph to as low as 40 mph. These issues are reported across various mileage ranges and are noted to pose safety risks, potentially leading to collisions or road rage incidents due to abrupt speed changes. Buyers should be aware of these software-related speed control issues when considering a purchase.

Owners report issues with the airbag systems of the 2024 Tesla Model 3, including disabled airbags due to damaged wiring in the passenger occupant sensing system and uncalibrated restraint control modules. Complaints frequently mention safety warnings about the restraint system, with some owners noting these warnings have become more frequent over time. One owner describes a crash where airbags did not deploy, with the vehicle having approximately 19,571 miles. Patterns suggest that some vehicles may have been sold with concealed damage or unaddressed safety faults, potentially affecting airbag deployment. Buyers should be aware of these potential safety implications when considering this model.

Owners report issues with the 2024 Tesla Model 3's lane departure and related systems, with some describing failures in the Full Self-Driving (FSD) feature. Complaints frequently mention the FSD's incorrect lane selection at specific intersections, leading to unexpected maneuvers such as moving into a left-turn lane when not intended or failing to merge as expected. One complaint involves a crash due to a backup camera's failure to provide audible alerts, resulting in significant damage. Another owner describes needing to swerve to stop an alarm. These issues are reported within the first year of ownership, and safety implications include potential crashes or incorrect lane positioning, which may be of concern to prospective buyers.

Owners of the 2024 Tesla Model 3 report issues with the back over prevention systems, specifically noting the lack of audible warnings or automatic braking when reversing. Complaints frequently mention that the vehicle fails to provide collision alerts or apply braking interventions, even in situations where obstacles are present, leading to at least one minor crash. One owner also reports a complete loss of camera functionality, diagnosed as an AP4 computer issue, though this was not covered by an existing recall. These problems are noted at various points in the vehicle's use, with no specific mileage range consistently mentioned. Safety implications include the potential for collisions due to insufficient warning or braking responses.

Owners report two main issues with the 2024 Tesla Model 3 power train. The first involves possible unintended acceleration, with two incidents leading to crashes; one while approaching a driveway and another in a fast food drive-thru, resulting in four injuries. The second issue involves the rear motor becoming disabled, as one owner describes the motor locking up at low speed, triggering alerts and causing the vehicle to stop suddenly. These issues highlight potential safety implications, including loss of control and the risk of collisions, which prospective buyers should consider.
