What is the 2012-2020 Tesla Model S Model S / X Drive Unit "Milling" Noise / Failure?
Early Model S (and X) drive units develop a "milling" noise — a metallic whine that gradually grows louder, ultimately requiring drive-unit replacement. Tesla has replaced many DUs under warranty (often multiple times per car). Issue stems from gear-mesh quality and bearing toler… Repairs typically run $0-$6,500. Severity: high.
What is the 2012-2019 Tesla Model S Drive Unit / Battery Coolant Leak (LDU Rotor Seal & Cooling Lines)?
Early Model S large drive units (LDU) have a known internal coolant leak where the rotor shaft seal fails and coolant migrates into the drive unit, and separately the battery/drive-unit cooling lines and fittings crack or seep with age. Leaks rarely show as a puddle; instead owne… Repairs typically run $300-$4,500. Severity: high.
What is the 2012-2021 Tesla Model S 12V Auxiliary Battery / DC-DC Converter Failure Cascade?
The low-voltage 12V lead-acid battery on early-to-mid Model S (concentrated in 2015-2018 build years) fails prematurely due to a poor original vendor cell plus constant vampire-load strain from always-on electronics. Roughly a third of Tesla NHTSA low-voltage complaints trace her… Repairs typically run $220-$1,800. Severity: high.
What is the 2012-2021 Tesla Model S Charge Port Door / Latch Actuator Failure?
The charge port door fails to open on command, or the internal latch fails to lock/release the charge cable. The actuator motor stops engaging the latch mechanism, or the electrical command isn't fulfilled, so the door won't 'push-to-open,' won't close, or the connector locks/unl… Repairs typically run $150-$700. Severity: medium.
What is the 2012-2020 Tesla Model S Retractable Door Handle Failure (Paddle Gear / Actuator Wear)?
The Model S's flush, auto-presenting exterior door handles are the single most-complained-about item on the car (the #1 issue in Consumer Reports' survey of ~1,300 owners). The small plastic 'paddle gear' inside the handle that transfers the pull to the latch cracks under materia… Repairs typically run $120-$600. Severity: medium.
What is the 2013-2021 Tesla Model S Electronic Parking Brake Caliper Seizure (EPB Motor Failure)?
The rear integrated electronic parking brake (EPB) calipers seize or the caliper actuator motor fails, throwing 'EPB_w053 - Parking brake did not release' or 'EPB_w052 - Parking brake functions degraded.' The caliper shaft can seize (often from moisture/corrosion in cars driven l… Repairs typically run $350-$1,600. Severity: medium.
What is the 2012-2020 Tesla Model S Model S / X Air Suspension Leveling / Nose-Droop?
Model S and X with air suspension develop leveling-pump and air-strut failures — typically presenting as a nose-droop overnight (car settles unevenly) or "Air Suspension Needs Service" warning. Pump diaphragm wear is the most common single cause; corner air struts also leak. Comm… Repairs typically run $500-$4,000. Severity: medium.
What is the 2012-2020 Tesla Model S Frunk (Front Trunk) Hood Latch Actuator / Cable Failure?
The front trunk ('frunk') fails to open on command because the electric hood latch actuator fails or the release cables corrode/seize or the latch goes misaligned. Owners hear the actuator working but the hood won't pop, or the dash reports 'front trunk / hood latch position unkn… Repairs typically run $0-$400. Severity: low.
What is the 2012-2020 Tesla Model S Power Window Regulator Failure (Plastic Ferrule Design Flaw)?
The window regulator on Model S doors fails because of a weak plastic ferrule in the regulator assembly that cracks, letting the glass come off its track or float free in the door. Owners report grinding/crunching or cracking noises raising and lowering the glass, glass that stic… Repairs typically run $20-$450. Severity: low.
