The second-generation 300C launched in the UK in 2012 on a Fiat/Lancia platform with a 3.0-litre V6 diesel. It was a far more reliable proposition than the first generation, with tried-and-tested Fiat mechanicals replacing the older Mercedes underpinnings.

What changed for 2012

  • •New Fiat/Lancia-derived platform
  • •Updated 3.0 CRD diesel with better emissions
  • •Improved interior quality and refinement
  • •Initially paired with older 5-speed auto (8-speed came later)

Common MOT watch-outs

  • !Suspension component wear remains common
  • !Electrical gremlins less frequent but still possible
  • !Check for proper service history on early 2012 models with 5-speed gearbox

All Known Issues

Suspension Bush & Ball Joint Wear

ModerateSuspension & Chassis

The 300C is a very heavy car, and its suspension components (derived from the Mercedes W211) take a beating on UK roads. Ball joints and control arm bushes often last less than 40,000 miles.

Est. Repair Cost: £300–£800
Warning Signs:

Knocking over speed bumps, Vague steering, Uneven tyre wear

What to Inspect:
  • 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.

Est. Repair Cost: £300–£700
Warning Signs:

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

What to Inspect:
  • Check the alternator output voltage
  • Inspect fuel hoses near the alternator for leaks
  • Check the earth cable for corrosion
