Most Common Honda Accord Mk6 Faults & Repair Costs

High Risk

Rear Arch, Sill and Floor Corrosion

Est. Cost£400–£1,800

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.

Warning Signs:

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

What to Check Before Buying:
  • 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

Moderate Risk

Front Suspension Bush and Ball Joint Wear

Est. Cost£200–£600

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.

Warning Signs:

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

What to Check Before Buying:
  • 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

Moderate Risk

Air-Conditioning Condenser or Compressor Failure

Est. Cost£250–£700

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

Warning Signs:

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

What to Check Before Buying:
  • 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

Essential Pre-Purchase Step

Buying a used Honda Accord Mk6? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Honda Accord Mk6 Buyers

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.
