Tesla FSD v14.3.6 Swerves Toward Ditch at 110 km/h on Quebec Highway

At 110 km/h on Quebec’s Autoroute 55, Tesla’s FSD v14.3.6 signaled for exit 217 after the ramp had already split off and steered toward the shoulder until the driver grabbed the wheel.
Dashcam footage showed dry pavement, clear lane markings, reflective signs and no traffic—conditions the driver described as close to ideal for Tesla’s supervised system, making the late exit attempt more alarming.
The intervention came as the speed readout fell from 110 to 102 km/h, with “Self-Driving” still displayed until takeover; the driver said the maneuver was a committed exit attempt, not a brief lane wobble.
Tesla’s release notes for v14.3.6 cite reinforcement-learning upgrades and a 20% faster AI compiler, but the report argues stronger performance can also breed driver complacency when failures remain rare and abrupt.
The incident adds to scrutiny of Tesla’s driver-assist safety claims as the company reported 207 Autopilot and FSD crashes to NHTSA in a single month and Elon Musk still predicts widespread unsupervised FSD by year-end.
