2020 Tesla Model 3 problems

“VEHICLE INFORMATION Make/Model/Year: Tesla Model 3 (2020) Component: Steering / Autonomous Control (ADAS) INCIDENT SUMMARY While driving on Autopilot/FSD southbound from [XXX], the vehicle experienced a sudden, uncommanded lateral steering excursion (phantom steering actuation) pulling abruptly toward the roadside shoulder. The driver had to immediately apply manual counter-steering torque to override the system and prevent a major collision. This unprompted steering correction caused the passenger side mirror structure to strike a roadside utility pole. KEY SAFETY FACTORS Sudden loss of directional control caused by computer-generated steering inputs rather than driver command or road obstruction. Quick driver intervention prevented a severe collision, but resulted in structural impact to the entire passenger mirror assembly. An official service ticket has been filed with the manufacturer requesting an immediate engineering telematics log pull (Steering Angle Sensor inputs vs. manual override torque, FSD state logs, and camera arrays) for the specific timestamp.”

“I own a 2020 Tesla Model 3 purchased in 2023 with Full Self-Driving (FSD) included for the lifetime of the car. I used FSD satisfactorily for years, but Tesla recently removed the maximum-speed control I previously used while FSD was engaged. I have personally experienced this change. FSD selects speed, but I can no longer impose the maximum I previously could set. I consider this a safety issue: unwanted speed requires the driver to detect it and intervene, potentially exposing occupants and other road users to excessive speed. The human driver remains responsible for safe, lawful operation and faces possible speeding tickets. I have read reports describing maximum-speed control as an "anti-pattern." I do not consider that an adequate safety justification for removing a preventive control. Learning a driver's preferences should operate within an explicit speed ceiling. I believe Tesla has the engineering capability to develop and validate a solution that preserves both FSD functionality and effective driver control. I request NHTSA investigate and require a remedy if a safety defect is established. My position is that affected FSD systems should not operate on…”

“I am reporting a premature and severe multi-component front suspension failure on my 2020 Tesla Model 3 that poses a serious steering and control safety hazard. While driving and turning at low speeds (such as parking), the front end began emitting a loud mechanical clicking and popping sound. A certified technician diagnosed the vehicle and found that multiple critical suspension components had failed or worn prematurely at just 55,089 miles. The failures include the front lower lateral links, front lower compliance links, front upper control arms, stabilizer bar and front end hubs failing completely and simultaneously. This is a well-documented issue among 2018–2020 Model 3 vehicles and is currently the subject of an active NHTSA Preliminary Evaluation investigation regarding front lower lateral link detachment. Premature failure of these load-bearing suspension components compromises the vehicle’s structural integrity, accelerates extreme tire wear, and presents an immediate risk of component separation or sudden loss of steering control at high speeds. Tesla should issue a safety recall for these defective suspension components and compensate owners for out-of-pocket repairs.”

“Lower Lateral Link Fronts and front lower compliance link assembly for both right and left. There have apparently been on going issues for the Tesla Model 3 suspension links. I first started hearing noises from the suspension last month, I was booked for a weekend service and then rescheduled for today. I stopped by for a formal comprehensive inspection and was informed that there is tearing in the suspension. I already had this vehicle brought in for warranty earlier this year, how was this not brought up to me during that time frame? Did the suspension suddenly start tearing after 6 months?”

“On July 11 at approximately 6:47 a.m., I was operating my Tesla Model 3 on Interstate 65 in Hart County, Kentucky, with Full Self-Driving (FSD) engaged during normal highway travel. Approximately one hour earlier, I had departed a highway rest area after sleeping from the previous day’s travel. Rain developed during the trip, but I observed adequate visibility, apparent roadway traction, and I was not impaired. I was traveling in the far-right lane of a three-lane interstate. The posted speed limit was approximately 70 mph; however, FSD limited the vehicle to approximately 65 mph and displayed warnings indicating that the higher speed was unavailable. While FSD remained engaged, the system initiated a lane change from the far-right lane into the center lane. After entering the center lane, the vehicle began displaying repeated warning messages and FSD disengaged multiple times. I attempted to locate settings related to the warnings on the touchscreen but could not identify an available adjustment. During the third disengagement, I perceived that the vehicle continued braking without releasing while steering resistance increased significantly. The steering wheel…”

“The contact owns a 2020 Tesla Model 3. The contact stated that while driving at an undisclosed speed, the safety features independently deactivated. The contact purchased and replaced the battery. The vehicle was taken to the dealer, where it was diagnosed with ECU failure. The contact was informed that the ECU needed to be replaced. The vehicle was not repaired. The contact stated that an unknown software update was completed in June 2026. In addition, the contact stated that the unknown software update caused the ECU to fail. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that the failure was a known failure with similar vehicles. The failure mileage was approximately 80,000.”
