Common Problems & Known Issues

The 2019 Model S is a well-sorted generation with fewer teething issues than earlier cars, but it still suffers from Tesla's trademark drive unit problems, screen failures, and suspension wear that can get expensive fast without warranty coverage.

Rear Drive Unit Failure (Milling/Whining Noise)

Occasional · high severity
Typical onset: 60,000-100,000 mi
Symptoms: High-pitched whine or milling sound from rear axle on acceleration, Clunking on light throttle transitions, Drivetrain fault message with reduced power
Fix: Tesla replaces entire drive unit assembly—not a rebuild. Independent shops can do R&R in 6-8 hours but you're sourcing a reman unit or salvage. Tesla warranty extension covered many, but out-of-pocket it's brutal.
Estimated cost: $5,000-8,500

MCU2 Screen Slowdown/Yellow Border Failure

Common · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Center touchscreen becomes sluggish or unresponsive, Yellow banding around screen edges, Backup camera delayed or frozen, Bluetooth/navigation crashing frequently
Fix: MCU (Media Control Unit) replacement required—Tesla charges flat rate, takes 3-4 hours. Some third-party shops offer MCU2 upgrades for older cars; verify yours has MCU2 already. This is the eMMC memory chip wearing out.
Estimated cost: $1,500-2,500

Upper Control Arm Bushing Failure

Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: Clunking over bumps from front suspension, Steering feels vague or pulls to one side, Premature inner tire wear, Visible cracks in rubber bushings on inspection
Fix: Front upper control arms with integrated ball joints need replacement. 2-3 hours per side with alignment after. OE Tesla parts only—no quality aftermarket yet. Heavy car eats bushings faster than comparable sedans.
Estimated cost: $1,200-2,000

12V Battery Premature Failure

Common · high severity
Symptoms: Car won't wake from sleep—doors won't unlock, Repeated warnings about 12V system needing service, Frunk won't open electronically, Complete loss of all functions despite full HV battery
Fix: The HV battery keeps the 12V charged, but the small lead-acid 12V runs all computers and door locks. Tesla's factory batteries fail in 2-4 years. Replacement is simple—1 hour max—but car is dead-dead when it goes. Keep a jump box handy.
Estimated cost: $200-400

Door Handle Mechanism Failure

Occasional · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Door handle won't present when approaching car, Handle extends but door won't unlatch, Grinding or clicking noise from door when unlocking, One handle works intermittently in cold weather
Fix: Motorized door handles have fragile plastic gears and microswitches. Each handle assembly is separate; 1.5 hours labor per door with trim removal. Front handles fail more often. Tesla redesigned these multiple times but even late 2019s aren't immune.
Estimated cost: $400-700

A/C Evaporator Coil Leaks

Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: A/C blows warm despite compressor running, Loss of refrigerant with no visible external leaks, Musty smell from vents (sometimes), HVAC fault codes pointing to low pressure
Fix: Evaporator is buried behind the dash—this is a 10-14 hour nightmare job. Dash removal, full evacuation and recharge of R-1234yf system. Independent shops can do it but it's tedious. Earlier Model S/X had worse problems; 2019s see it less but still happens.
Estimated cost: $2,500-4,000

Air Suspension Compressor/Strut Failures

Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Suspension fault message with car sagging on one corner, Compressor runs constantly or won't raise car, Rough ride—feels like riding on bumpstops, Visible fluid leak from air strut
Fix: Air suspension cars (not all 2019s have it) can fail at compressor or individual struts. Compressor replacement is 3-4 hours; struts are 2-3 hours each. Aftermarket coilover conversions exist for $3k-4k if you're done with air. Check build sheet—some have coil springs from factory.
Estimated cost: $1,800-3,500
Owner tips
  • Change drive unit fluid every 50k miles even though Tesla says lifetime—it's cheap insurance against $7k drive unit replacement
  • Keep the car plugged in daily to maintain 12V battery health—long sits without charging kill the 12V fast
  • Budget $150-200/year for annual brake fluid flush—regen braking means calipers don't get exercised and pistons seize
  • Check suspension bushings and ball joints at every tire rotation—this car is heavy and eats front-end parts
  • If buying used, verify MCU2 is installed and ask for screen responsiveness test—MCU1 cars are ticking time bombs
Solid platform if you find one with fresh drive units and MCU2, but factor $2k-3k/year for out-of-warranty surprises—battery and motors are robust, everything else is typical luxury-car money.
