2012 Tesla Model S
Common problems & what to know before you buy
Before you message the seller, know the documented failure patterns, repair cost exposure, and risk level for the 2012 Tesla Model S.
What to watch for on the 2012 Tesla Model S
Drive Unit Failure
Early drive units developed a milling or whining noise and were replaced under warranty in very large numbers. Out of warranty this is the single most expensive routine failure on the car. Ask how many replacements the car has had and when.
MCU1 eMMC Flash Failure
The original media control unit uses flash memory that wears out from constant logging, eventually causing a black screen and loss of climate, charging, and reversing camera control. Tesla extended warranty coverage on it. The fix is an eMMC replacement or an MCU2 upgrade.

2012 Tesla Model S price ranges
Prices vary enormously with service history rather than mileage. A car with a documented recent drive unit and MCU replacement is worth several thousand more than a cheaper one without, because those are exactly the repairs the next owner would otherwise face. Free unlimited Supercharging, where it transfers, adds real value on a high-mileage car.

Tesla Model S (2012-2015) Buyer's Guide
Drive Units, MCU, and Free Supercharging
The pre-facelift Model S is the cheapest way into a genuinely fast luxury EV, and the riskiest. These cars are now over a decade old, and the failure modes are well documented rather than mysterious: drive units, the media control unit, door handles, and the air suspension. A well-sorted example with documented repairs is a rewarding car. A cheap one with no history is a money pit, and the gap between the two is often only a few thousand dollars at purchase.
Trims: the naming describes battery and motor layout. RWD cars are 40, 60, 85 and the performance P85. All-wheel drive arrived with the dual-motor D cars in late 2014: 70D, 85D, 90D and the performance P85D and P90D. The 40 was a software-limited 60 and is rare.
The one thing that can make an old Model S worth it: many cars from this era carry free unlimited Supercharging tied to the vehicle rather than the owner, and on a great many of them it transfers on resale. On a high-mileage car that perk is worth real money. Verify it in the car's own charging menu, not from the seller's description.
What to look for: Ask directly whether the drive unit has been replaced and how many times, since early units were replaced under warranty extremely often. Check whether the MCU is the original MCU1 with its failing flash memory or has been upgraded. Work all four door handles repeatedly. Cycle the air suspension through every height. Check the rated range at a high state of charge against the original figure for that battery.
About the 1st Gen
The pre-facelift Tesla Model S, built from 2012 to 2015 and recognisable by its black nose cone, was the car that proved a long-range electric sedan could work. Trim names describe the battery and motor layout rather than equipment: rear-drive 40, 60, 85 and the performance P85, joined from late 2014 by the dual-motor all-wheel-drive D cars including 70D, 85D, 90D, P85D and P90D. The 40 was a software-limited 60 and is rare. These are now cars well over a decade old, and they are the cheapest route into genuinely fast, spacious electric motoring.
They are also the riskiest Tesla to buy, though the failure modes are thoroughly documented rather than mysterious. Early drive units developed a milling or whining noise and were replaced under warranty in very large numbers. The original MCU1 media control unit uses flash memory that wears out, eventually taking the touchscreen, climate and charging controls with it. Auto-presenting door handles fail routinely, the Smart Air Suspension fails with age, and packs of this era have typically lost 10 to 20 percent of their capacity. The result is that service history matters far more than odometer reading: a car with documented drive unit and MCU work already done is worth several thousand more than a cheaper one without. Many cars from this era also carry free unlimited Supercharging that transfers with the vehicle, which is worth real money and should be verified in the car's own charging menu.

Frequently asked questions
Is a 2012-2015 Model S too risky to buy?
Not inherently, but it demands a different approach than a normal used car. The major failure modes are known and documented, so a car with records showing the drive unit, MCU, and door handles already addressed is a far safer purchase than a cheaper one with no history. Budget a repair fund either way.
How do I check if free Supercharging transfers?
Look in the car's own charging menu on the touchscreen, which shows whether free unlimited Supercharging is attached to the vehicle. Do not take the seller's word for it, and do not rely on the listing. Many but not all cars from this era carry it, and it is worth real money.
What does a battery replacement actually cost?
Typically $12,000 to $20,000 through Tesla for a pack of this era, which frequently exceeds the value of the car. Third-party rebuilders and refurbished packs are cheaper. This is why documented battery health matters more than odometer reading on these cars.
MCU1 or MCU2, and does it matter?
It matters. MCU1 uses flash memory that wears out and eventually fails, taking climate and charging controls with it. An MCU2 upgrade fixes it permanently and brings a much faster interface. A car already upgraded has removed one of the two biggest cost risks.
Which is better, air suspension or coil springs?
For a used buyer of this age, coil springs. They cannot fail the way an air system can, and air suspension repair is one of the more common four-figure bills on these cars. Air rides better when working, which is the trade-off.
