  • •Electronic Throttle Control (ETC) light
  • •Engine management light

What to inspect before you buy

  • ✓Check for oil residue around the turbo inlet
  • ✓Ask if a "resistor mod" or swirl motor bypass has been fitted

Suspension Bush & Ball Joint Wear

ModerateSuspension & Chassis

Most affected: All models

Estimated cost: £300–£800Affects: 2005–2015

Typical symptoms

  • •Knocking over speed bumps
  • •Vague steering
  • •Uneven tyre wear

What to inspect before you buy

  • ✓Service history for suspension work
  • ✓Listen for knocks during test drive
  • ✓Inspect front tyres for inner edge wear

Alternator Failure

ModerateElectrics & Electronics

The alternator is prone to premature failure, often caused by diesel fuel dripping onto it from cracking rubber fuel hoses. The earth cable can also corrode, leaving the car unable to start.

Most affected: 3.0 CRD Diesel

Estimated cost: £300–£700Affects: 2005–2015Often appears around: 50,000–100,000 miles

Typical symptoms

  • •Battery warning light
  • •Car failing to start
  • •Dimming lights
  • •Electrical glitches

What to inspect before you buy

  • ✓Check the alternator output voltage
  • ✓Inspect fuel hoses near the alternator for leaks
  • ✓Check the earth cable for corrosion

Buying Tips for the 2008 Chrysler 300C

  • ✓Listen for "knocking" from the front suspension over bumps; it usually means worn control arms or ARB bushes.
  • ✓On diesel models, check for the "red lightning bolt" warning light, which can indicate swirl motor or electronic throttle issues.
  • ✓Verify that the alternator is charging correctly, as failures are common and can leave you stranded.
  • ✓The facelift models (late 2008 onwards) have a much-improved interior and slightly better electrical reliability.
  • ✓Touring (Estate) versions are highly practical but check for sagging rear self-levelling suspension.
