2019 Tesla Model 3 Reliability Report

Front upper control arm ball joints wear early. The first sign is a squeak over bumps or while turning, which grows into a clunk under acceleration. Repairs often include the upper arms plus the lower lateral and compliance links. Many owners hit the problem just past the 50,000-mile warranty and pay themselves. A service bulletin exists, but service centers now replace the arms instead of resealing them. Rarer reports describe a control arm separating while driving and leaving the car undrivable. Several crash reports come from third parties citing salvage-yard cars.

A front passenger safety restraint system fault warning is the most common issue, often tied to the passenger seat occupancy sensor. It brings a recurring beep, and owners worry the airbag may not deploy. Repair quotes run from over $750 to $1300. A service bulletin calls for retrofitting the passenger seat sensor, and rodent-chewed seat wiring caused one fault. Separately, crash reports describe airbags not deploying in side impacts and frontal hits. One report describes the airbags firing with no collision.

A creak or rusty-hinge noise when turning the wheel usually traces to worn front upper control arms, sometimes with a loose inner tie rod. One owner heard it at about 44,360 miles, just out of warranty. More serious reports describe power steering assist dropping out with a steering assist reduced message, leaving the wheel heavy or locked. A restart clears it temporarily, but it comes back. One water-damaged steering rack cost over $5,000 to repair. Crash reports include a fatal lane-keeping failure claim and third-party salvage-yard filings.

This catch-all category mixes several problems. Sudden braking on Autopilot or Full Self-Driving with no obstacle shows up repeatedly, and once it caused a crash behind the car. Others describe unintended acceleration while parking, a car lurching backward at a red light, and the self-driving system missing a vehicle stopped on the shoulder. Cabin heat can quit in subzero weather, and range drops sharply in the cold. Software updates that hid the defrost, wiper, and seat heater controls draw safety complaints. Five reports involve crashes.

Phantom braking at freeway speeds dominates. The car brakes hard or gives a false collision warning on an empty road, sometimes at the same spot every trip, and one report describes all four wheels locking. A separate mechanical problem is brake lines that rupture or rust through in the front wheel well. They leak fluid and set off a low brake fluid alert, and owners say warranty claims were denied. A few crash reports claim the brake pedal failed to stop the car while it accelerated.

Most excerpts are one series of video reports on a single Full Self-Driving Beta version. They show the car drifting into bike lanes, closed lanes, or oncoming traffic, and passing too close to parked vehicles. Outside that series, Autopilot drifts across lanes. Condensation inside the B-pillar cameras makes them cut out at highway speed. At night, turn signal glare washes out the blind spot camera view. One crash involved hydroplaning into a median at about 66,000 miles.

The underbody aero shield soaks up water in heavy rain, then tears loose and drags, sometimes throwing sparks. A service bulletin called for a replacement shield, but owners say the new part fails the same way, and repairs outside warranty are billed. Glass roofs and rear windows crack from small falling nuts or with no clear cause, and one replacement cost over $2000. Other complaints cover frozen door handles, a door handle that tore a fingernail, and a fragile frunk bracket that often breaks during factory installation.
