What changed for 2022

  • •Lithium 12V battery standard
  • •Ryden MCU3 processor — 5× faster than MCU2
  • •Heated wipers standard
  • •Improved build quality on Chinese-built models
  • •Best efficiency of the Classic generation

Common MOT watch-outs

  • !Upper control arm squeak at 15,000–40,000 miles
  • !Rear light condensation
  • !Paint durability remains a concern on sills

All Known Issues

Heat Pump / Sensor Failure (SB-22-18-002)

SeriousCooling System

2021 and early 2022 "refresh" models with heat pumps can experience a loss of heating in winter. This is often caused by faulty refrigerant pressure sensors (Recall SB-22-18-002) which can fail and prevent the compressor from operating correctly.

Est. Repair Cost: £0–£1,500 (often warranty)
Warning Signs:

No cabin heat in cold weather, Defrost function fails, Loud grinding noise from the front

What to Inspect:
  • Verify the heater works on max setting in cold conditions
  • Check for climate-related alerts in the service menu
  • Confirm if Service Bulletin SB-22-18-002 has been addressed

Upper Control Arm Failure

ModerateSuspension & Chassis

The front upper control arms frequently develop a loud squeaking or "old bed spring" creaking noise due to water ingress into the ball joint. This is very common in the UK due to wet weather and road salt.

Est. Repair Cost: £300–£600
Warning Signs:

Loud squeaking when turning or over bumps, Knocking noise, Steering feel changes

What to Inspect:
  • Listen for creaking while stationary by turning the wheel
  • Check if the arms have been replaced with the updated part (plastic vs metal housing)

Rear Light Condensation

MinorElectrics & Electronics

Water ingress into the rear light clusters is common, often leading to visible condensation and eventual failure of the LED units.

Est. Repair Cost: £200–£400 (per unit)
Warning Signs:

Visible water droplets inside lights, Flickering LEDs, MOT failure for light function

What to Inspect:
  • Inspect lights after rain or a car wash
  • Look for green algae growth inside lens
  • Verify all LED segments work

Paint Durability & Stone Chips

MinorBodywork & Rust

The paint on Model 3 is known to be relatively soft, making it highly susceptible to stone chips and "sandblasting" on the rocker panels and sills.

Est. Repair Cost: £200–£1,000 (PPF/Respray)
Warning Signs:

Visible chips on bonnet and sills, Paint flaking near wheel arches, Dull finish on lower panels

What to Inspect:
  • Inspect the lower sills and rear wheel arches
  • Look for "sandblasting" effect behind wheels
  • Check if mud flaps or PPF are installed
