2016 TESLA MODEL S

Typical onset: 60,000-100,000 mi

Symptoms: whining, humming, or clunking from rear axle, drivetrain vibration at highway speed, milling noise on acceleration, occasional total loss of propulsion

Fix: Drive unit replacement or rebuild. Tesla warranty covered many, but out-of-warranty units run 8-12 hours labor plus remanufactured drive unit. Independent shops can swap units but sourcing and programming requires Tesla cooperation or third-party workarounds.

Estimated cost: $5,000-9,000

Typical onset: 80,000-120,000 mi

Symptoms: rapid range loss beyond normal degradation (>20% capacity drop), brick warnings or BMS faults, car won't charge past certain percentage, reduced power output and limp mode

Fix: Full pack replacement is $12k-22k depending on capacity. Some shops can replace individual modules (16-module packs) for $2k-4k if only one or two are bad, but diagnostics require Tesla scan tools or third-party equivalents. Labor is 10-14 hours for full pack, 6-8 for module replacement.

Estimated cost: $3,000-22,000

Symptoms: car won't wake up or start, clicking from under rear seat area, error messages about contactor open/close failure, total loss of drive with dash warnings

Fix: Contactor replacement inside HV battery assembly. Requires disconnecting HV system, removing pack access covers. 4-6 hours labor. Parts are $800-1,500 depending on whether you get OEM or aftermarket.

Estimated cost: $1,500-3,000

Symptoms: handles don't extend when approaching car, handles stuck retracted or partially extended, grinding noise from door when unlocking, intermittent function in cold weather

Fix: Door handle actuator replacement. Each handle is 1.5-2 hours labor (door panel removal, careful cable routing). Revised Gen 2 handles are more reliable. Most owners end up replacing multiple handles over ownership.

Estimated cost: $500-800 per handle

Typical onset: 70,000-100,000 mi

Symptoms: yellow border around touchscreen, extremely slow screen response or black screen, navigation and backup camera not working, continuous reboot loops

Fix: MCU board repair (eMMC chip replacement) or full MCU upgrade to newer hardware. Board-level repair by specialists runs $500-700. Tesla's MCU2 upgrade is $1,500-2,500 installed and solves the issue permanently. DIY chip replacement possible but requires microsoldering skills. 2-3 hours labor for swap.

Estimated cost: $500-2,500

Symptoms: car completely dead, won't unlock or respond, repeated warnings about 12V battery needing service, random module faults and warning lights, frunk won't open electrically

Fix: Replace 12V lead-acid battery. Unlike traditional cars, the DC-DC converter charges this from HV pack, but early Model S units had weak charging logic. Battery is in frunk area, 0.5-1 hour labor. Tesla-specific battery preferred but standard group-size AGM works. Some owners proactively replace every 3-4 years.

Estimated cost: $200-400

Typical onset: 60,000-90,000 mi

Symptoms: suspension compressor running constantly, car sagging overnight or sitting lower on one corner, suspension fault warnings, rough ride or inability to raise suspension

Fix: Compressor or valve block replacement, sometimes air spring replacement if leak is at bag. Compressor is 2-3 hours, valve block is 3-4 hours. Air springs are $400-600 each plus 2 hours labor per corner. Diagnosis requires leak detection (soapy water method or ultrasonic).

Estimated cost: $1,200-3,500
