All Known Issues

Rear Arch, Sill and Floor Corrosion

SeriousBodywork & Rust

Rust around the rear arches, sill ends and floor edges is the defining UK problem on surviving Mk6 Accords, and welding costs can quickly exceed the value of average cars.

Est. Repair Cost: £400–£1,800
Warning Signs:

Bubbling paint on rear arches, Crusty sill seams, Historic MOT corrosion advisories

What to Inspect:
  • Inspect the jacking points and inner sills
  • Look inside the rear wheel arches for fresh underseal hiding repairs
  • Read the MOT history for structural corrosion notes

Front Suspension Bush and Ball Joint Wear

ModerateSuspension & Chassis

The Accord’s front suspension usually stays quiet for years, but ageing bushes and lower ball joints eventually cause knocks, vague steering and uneven tyre wear.

Est. Repair Cost: £200–£600
Warning Signs:

Clonk over potholes, Vague steering, Inner-edge front tyre wear

What to Inspect:
  • Drive on broken surfaces with the radio off
  • Check for split bushes and joint play during the underside inspection
  • Look for uneven wear across the front tyres

Air-Conditioning Condenser or Compressor Failure

ModerateCooling System

Older Accords often lose air-conditioning performance because the front condenser corrodes or the compressor clutch wears out.

Est. Repair Cost: £250–£700
Warning Signs:

Air conditioning blows warm, Compressor clicks but no cold air, System loses gas after a regas

What to Inspect:
  • Run the climate control until the cabin should be fully cold
  • Inspect the condenser for oily staining or heavy corrosion
  • Listen for noisy compressor operation at idle

Buying Tips for 2003 Honda Accord Mk6

  • Inspect the rear arches, sills and floor edges thoroughly because corrosion is what usually kills a Mk6 Accord.
  • Listen for front suspension knocks over rough roads and budget for bushes or ball joints on original cars.
  • Test the air conditioning properly; condenser and compressor issues are common enough on older examples.
