2026 TESLA MODEL 3 Complaints

When using Tesla's Full Self Driving (supervised) speed control is erratic and not subject to the driver's control, such as it would be when using adaptive cruise control. As a result, the available speed modes (sloth, chill, standard, hurry and Mad Max) can cause the vehicle to dangerously exceed speed limits and at times to drive well below the posted speed limit, causing confusion and frustration to following drivers. There is no reason why the software cannot be changed to a safer method that would permit the driver to select the speed at which the car will travel, i.e. the speed limit, similar to adaptive cruise control found in most modern vehicles. When the operator of a vehicle is not in charge of the vehicle's speed, this is inherently dangerous.

My Tesla was operating under FSD at 9pm on a dark country road. I was traveling at 45mph and vehicle randomly applied hard emergency braking and I had to take over. It appeared that the vehicle may have been responding to a dark oil stain or possibly a mailbox. Had another vehicle been closely behind me, there would’ve been a collision.

On August 26, 2026, at approximately 8:56 AM, I entered a public parking garage in Washington, DC. Full Self-Driving (Supervised) was engaged and controlling the vehicle during a reversing maneuver. I remained attentive to the vehicle's surroundings, including pedestrians and surrounding traffic. While reversing under FSD (Supervised), the vehicle's right rear corner collided with the corner of a stationary structural pillar in the parking garage. I did not command the vehicle to steer into the pillar. Upon becoming aware of the impact, I immediately applied the brake. There were no injuries. The collision resulted in damage to the right rear area of the vehicle. After the incident, I photographed and recorded the scene and vehicle damage and saved the available Tesla Dashcam footage. I also requested the vehicle data from Tesla. I am reporting this incident because the vehicle collided with a stationary structure while FSD (Supervised) was engaged and controlling the reversing maneuver. I do not know the specific technical cause of the incident. The vehicle and available recorded data can be made available for inspection upon request.

“The affected system was Tesla Full Self-Driving (FSD) (Supervised). FSD correctly selected the northbound left-turn lane but, while executing the left turn to westbound Pecan Street, intermittently directed the vehicle into the eastbound lanes carrying opposing traffic.”

Driving on a 2 lane road going 65 with Traffic-Aware Cruise Control enabled at 65 MPH with a car behind and no car in front of us. the car phantom braked for no reason going from 65 to 40 mph in a matter of seconds. Luckily we were able to accelerate to avoid being rear ended

The vehicle is experiencing severe, unpredictable software and hardware regressions related to the Full Self-Driving (Supervised) system (v14.3.7, Software build 2026.21.5) that create an immediate, active traffic hazard and a high risk of rear-end collisions. Primary Safety Issues: 1. TRAFFIC STALLS UPON DISENGAGEMENT: When Full Self-Driving (FSD) is engaged, auxiliary sensors malfunction, causing the headlights to cycle on/off and windshield wipers to run at full speed in clear, dry, midday daylight. When attempting to manually disengage FSD to correct these malfunctioning systems, the vehicle fails to smoothly transition control. Instead, it triggers critical red flashing alert lights, sounds severe warning chimes, and initiates an immediate, aggressive brake application—stopping the vehicle dead in active, live traffic. 2. PHANTOM BRAKING: The vehicle routinely experiences sudden, severe, and unprovoked phantom braking events while driving at speed, without any forward obstacles or environmental hazards present. 3. STEERING INSTABILITY: When navigating parking lot entrances, the vehicle exhibits extreme "indecisive behavior," resulting in violent, rapid shaking of the steering wheel before completing the maneuver. Tesla customer service was formally notified of these dangerous system behaviors on August 14, 2026. A formal remote engineering log review has been requested from the manufacturer, as these sudden braking actions in active traffic pose an immediate threat to public safety.

I purchased my car on 3/23/26. Since delivery I have noticed that the car bounces at low speeds 20-30mph and the steering wheel vibrates at highway speeds 65 - 80mph. I have had the car to tesla service center 6 times since march. They have replaced all 4 tires, found and replaced a bent wheel (rim) on the passenger side. Then this last visit they replaced the passenger right wheel hub. They claim that when comparing it to the 1 other car available to road test my car was the same even though it still has the wheel vibration at highway speeds. they claim it falls within specs and is safe. I do not feel this is acceptable because they dont know what else to do. Now if I want them to check the car they say I must pay for any diagnosis and repairs if needed because they say they fixed the car. I do not feel safe driving at highway speeds as I am not sure what may happen which could endanger myself or passengers

The horn system on the new Tesla are not effective. Other drivers cannot hear The unit is facing the ground, and a high speed. Other drivers. Can I hear it specially when it’s raining. The use of the original point was effective and never had a problem on my previous last Tesla, or any other car for that matter. Please help before a serious. Ask her that happens.

After a recent Tesla software update, a mandatory Full Self-Driving disengagement feedback window appears every time I disengage FSD while the vehicle is still moving. The feedback window covers a large portion of the display with a black overlay, noticeable enough something popped up. There is no setting to disable it, dismiss it immediately, or postpone the response until the vehicle is stopped. I am required to select a disengagement reason before I can access the controls and information behind the overlay. While this window is displayed, I cannot properly view or control functions such as music and other touchscreen features behind the area. This is especially dangerous because it appears immediately after I take manual control from FSD—a moment when my full attention should be on the road and the vehicle. The system effectively requires me to look away from the road and interact with the touchscreen before I can make another needed adjustment. This occurs every time I disengage FSD and is consistently reproducible. This behavior began after software version FSD v14.3.3. My vehicle is a 2026 Model 3. The problem occurred everytime while traveling at any speed. I believe this mandatory, non-dismissible overlay creates a serious driver-distraction hazard by obstructing the center display and requiring touchscreen interaction while the vehicle is in motion. Tesla should allow the feedback request to be dismissed, delayed until the vehicle is parked, or disabled entirely.

Air Suspension Failure - Damping Control Disabled (Code TAS_a313)" Description: "Vehicle is 2 days old. Suspension control module lost communication with CAN bus. Vehicle is in 'fail-safe' mode. Tesla Service Center has refused to assist. Safety risk due to loss of adaptive ride control." Manufacturer Response: "No response / Ignored."
