2021 Tesla Model 3 — Common Problems Owners Report

The dominant pattern in owner complaints centers on the forward collision avoidance system, where owners report the vehicle failing to slow down when expected and also applying sudden, hard braking on the highway with no warning and no visible obstacle. Secondary clusters cover the braking and speed control systems — specifically the removal of a low regenerative braking option that owners expected from their test drives — and electrical system faults that cause climate control heating to stop working.

Most reported areas

Forward Collision Avoidance safety 63%

Owners report the system failing to reduce speed when approaching a hazard, and also triggering sudden, unexplained hard braking on the highway with no warning and no obstacle present. · 1 fire · 10 crash · 8 injured

Service Brakes safety 19%

Owners report that a low regenerative braking setting available during test drives was not present at delivery, removing the expected coasting behavior when lifting off the accelerator. · 1 fire · 11 crash · 5 injured

Vehicle Speed Control safety 19%

Owners report that the low regenerative braking mode experienced during test drives was unavailable after delivery, altering how the vehicle decelerates when the accelerator is released. · 11 crash · 6 injured

Electrical System safety 11%

Owners report that cabin heating stops functioning, with the fault apparently tied to humidity and temperature sensors that must operate correctly for the heating system to work. · 1 fire · 7 crash · 4 injured

Lane Departure safety 4%

28 reports (4%) · 5 crash · 1 injured
