Kestrel Take
The Model 3 is genuinely excellent as an EV and has improved substantially in build quality. Battery degradation and Autopilot recall status are the two things to check. Get the battery health report before anything else.
What we checked
Reconciled against public records, 2026-09-25
NHTSA holds 449 owner complaints for the 2020 Tesla Model 3, and 21 recall campaigns.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 35% of them are about one thing — the driver-assist and automatic braking systems. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.
21 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Source: not yet checked against public records.
The forward-collision system can misread a shadow, an overpass, or a car in the next lane as a collision threat and slam the brakes for a fraction of a second, even on a clear highway. It's a software behavior rather than a broken part, but it's the subject of a NHTSA investigation covering hundreds of thousands of Tesla vehicles including this one, and it's a genuine rear-end-collision risk for whoever is behind you. Ask whether the car is on a recent software version; there's no dealer part to fix, only updates.
Repair cost: Not yet priced — a safety matter first, a repair bill second
Source: NHTSA complaints filed under throttle and cruise control (69).
