2020 Tesla Model 3 forward collision avoidance 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.”

“All Teslas vehicles running HW3 / AI3 Autopilot self driving computers have been known for years to have a defective design problem with the cooling system without its own dedicated cooling and which puts the self driving computer last in the cooling looping at the top of the cooling stack. When the computer fails and they will Tesla requires the owner to replace the computer. This does not result in a redesigned improvement to the computer or cooling system that reduces the thermal stress being applied to the new computer. Tesla is now pushing a new version of the self driving FSD software with the “v14 Lite” release over the last two weeks. This software release uses large complex software models which Tesla design to use every part of the HW4 / AI3 compute power which stressed the computer by pushing it to it compute limiting. All this compute is causing the computer to overheat and fail. Tesla then require owners who are all out of warranty now to pay thousands to replace the computer. This replacemen uses the same flawed cooling system and the same computer incapable of dealing passive compute requests on it by the latest v14 Lite software to eventually…”

“Car was sitting at a red light while in Full Self Driving (supervised). The screen showed at least four red lights. Suddenly the car started to move forward while the lights were still red. I was able to stop it from going further. This has happened before and I reported it then. If I had not had my foot near the brake pedal the car might have just run through the light.”

“Tesla was on Full Self Driving following a curve in the road were traffic lights. Lights were red Car should have stopped but did not. Ran red light with no attempt to stop or slow down.”

“Driving S/B on Ann Arbor Saline Road. Had FSD on the Tesla engaged. Needed to make left turn onto Maple. Left arrow light to Maple was red. Traffic light to continue straight on Ann Arbor-Saline was green. Despite left arrow being red, Tesla did not slow and ran red light to make left turn onto Maple.”

“When adaptive cruise control is enabled (Autopilot, not equipped with Full Self Driving) car will sometimes brake hard as if there is an obstacle ahead, with the words "Curve Assist Active" flashing on the screen. Seems to happen most often on state highways, vs interstate. In one case last night car slowed from 65mph to 30mph, on a straight road, with no object ahead. Thankfully no cars were immediately behind or I would have been rear-ended. Happened 4 times in 500 miles of highway travel.”
