All Known Issues

Cooling-system leaks and overheating

SeriousCooling System

Radiators, hoses and thermostat housings can age badly, and a PT Cruiser that has overheated even once is a much riskier proposition than the price suggests.

Est. Repair Cost: £150–£900
Warning Signs:

Coolant smell, Temperature rises in traffic, Low coolant level, Heater performance fluctuates

What to Inspect:
  • Inspect radiator and hose joints
  • Let it idle until fully warm
  • Avoid any car with unexplained coolant top-ups

Front suspension bush and ball-joint wear

ModerateSuspension & Chassis

The PT Cruiser is heavy for its size and wears front suspension parts regularly, which creates knocks, vague steering and repeat MOT advisories.

Est. Repair Cost: £180–£500
Warning Signs:

Clonks over bumps, Loose steering feel, Uneven front tyre wear

What to Inspect:
  • Drive it on rough roads
  • Inspect tyres and MOT history
  • Check for recent lower-arm or ball-joint invoices

Est. Repair Cost: £80–£500
Warning Signs:

Cranks but will not start, Random warning lights, Windows or central locking fail intermittently

What to Inspect:

Buying Tips for 2003 Chrysler PT Cruiser

  • ✓Check the front suspension for knocking; the lower control arm bushes are a notoriously weak point and require frequent replacement.
  • ✓Verify the timing belt and water pump have been changed; the engine bay is cramped, making this a labor-intensive and costly job.
  • ✓Inspect the interior plastics and seats for heavy wear, as the cabin materials are fairly cheap and prone to cracking.
  • ✓Test the air conditioning, as the system is known for leaks and compressor failures.
  • ✓Look for rust around the door bottoms, tailgate, and particularly the front subframe, which can lead to MOT failure.
  • ✓On convertible models, check the operation of the roof and inspect the rear glass window seal for leaks.
