Kestrel Take

The pre-refresh Model S at its cheapest, and the record is about the software and the front end rather than the drivetrain. Twenty-nine percent of the 80 complaints are forward collision avoidance — phantom braking, the car hitting the brakes hard on an empty interstate — and suspension and steering account for another 30% between them: cracked front knuckles, control arms loose by 33k miles, half shafts replaced twice. NHTSA lists no recall campaign against this model year, which is a fact about the record and not a promise about the car. Take it on a long highway drive with Autopilot engaged, drive it over something rough at 20 mph, and find out how much battery and drive unit warranty is left before you talk price.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 80 owner complaints for the 2020 Tesla Model S, and 11 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. The largest single group is the driver-assist and automatic braking systems at 29%. That is notable without being overwhelming — worth checking, not worth panicking about.

11 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.

Known Issues for the 2020 Tesla Model S

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Phantom braking — the car brakes hard for nothing at highway speedHigh — wallet impact

Twenty-three complaints, 29% of the record and the biggest cluster by a distance. Owners set cruise or Autopilot at 55–85 mph and the car suddenly sheds 20 mph or stops dead with clear road ahead. The triggers owners name are overpass shadows, oncoming high beams at night, and cars passing on the right. Two of these reports involve a crash. There is no part to replace — this is how the system behaves — so the only honest test is a long highway drive with Autopilot engaged before you buy.

Repair cost: Not yet priced — a safety matter first, a repair bill second

Front suspension: cracked steering knuckles and control arms going looseHigh — wallet impact

Fourteen complaints, 18% of the record. Two are salvage-yard reports of a front steering knuckle snapped clean in half; another describes front-end components loose at 33,000 miles until the tire rubbed the fender liner, and one owner blames a highway tire blowout at 10,000 miles on the way this car wears its front tires. It is a 4,900 lb sedan on air springs and it is hard on front components. Pay a shop to put it on a lift and check knuckles, upper and lower control arms and ball joints for play before you hand over money.

Repair cost (estimate): $700–$2,600 per corner at an independent EV shop, more at a Tesla service centre

Half shafts shudder under power, and power steering assist can drop outHigh — wallet impact

The ten steering complaints split two ways. Several are front half shafts replaced and then replaced again inside two years, with vibration and a popping noise under hard acceleration — one owner was told by a Tesla service adviser that they fail often at that mileage. The rest are a 'steering may require extra force' message followed by the loss of power assist, cruise control and collision warning all at once, which owners trace to corroded ground connections. On the test drive, accelerate hard from 20 mph and feel for shudder coming up through the floor.

Repair cost (estimate): $700–$1,800 per half shaft; $1,500–$2,600 for a steering rack

The 12-volt battery strands the car when it finally goesLow

This is the pre-refresh car, so the 12V is an ordinary lead-acid battery, and it runs the door handles, the screens and the contactors that let the main pack do anything. When it dies the car will not open or move even with a full traction battery, and the warning is often a single screen message a day or two beforehand. They last roughly three to four years, so a 2020 is on its second or third. Ask for a dated replacement receipt and budget for the next one.

Repair cost (estimate): $150–$400

Walk-Away Red Flags

✗A clunk or pop from the front end going slowly over a speed bump
✗Shudder through the floor when you accelerate hard from about 20 mph
✗Any 'steering assist reduced' or 'power steering may require extra force' message on the screen
✗Autopilot braking for an overpass shadow or an oncoming high beam during the test drive
✗A rated range at full charge far below the roughly 370–400 miles this car left the factory with

Good Signs

✓Service records showing front upper control arms or half shafts already replaced under warranty
✓A dated receipt for the 12V battery within the last two years
✓A quiet, settled front end over a rough road at 20–30 mph
✓Rated range at 100% within about 10% of the original EPA figure
✓Battery and drive unit warranty still running — 8 years and unlimited miles from this car's in-service date, which Tesla will confirm from the VIN
