Common Problems with the
2017 Lotus Elise S3

Major mid-cycle refresh introduces aggressive open-mesh front bumpers, exposed aluminium gear linkage, 10kg weight reduction, and iconic Sport 220, sub-800kg Sprint, and Cup 250 variants.

What changed for 2017

  • •Exposed open-gate aluminium gear linkage mechanism improving shift precision
  • •Restyled front bumper with enlarged radiator air intakes and single round taillight units
  • •Weight-saving program shedding 10kg, including optional lithium-ion battery and carbon seats
  • •Sprint edition launched reaching 798kg dry weight, alongside revised Cup 250 track edition

Common MOT watch-outs

  • !Tyre tread depth below legal limits across aggressive track-biased Yokohama rubber
  • !Headlamp aim misalignment and insecure low-mounted aerodynamic carbon splitters
  • !Suspension rose-joint play and anti-roll bar link wear on Cup variants

All Known Issues

Front Radiator & Condenser Corrosion

ModerateCooling System

Being mounted low and exposed, the cooling pack corrodes over time, especially on cars driven in winter.

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

Loss of A/C performance, Slow coolant drop, Visible debris in radiator fins

What to Inspect:
  • Inspect the cooling pack through the front grilles with a torch.

Gearbox Synchro Wear (2nd & 3rd)

ModerateGearbox & Transmission

The supercharged 1.8 S3 models are particularly prone to synchro wear on 2nd and 3rd gears, often flagged by crunching on the 2-3 change. Cars used on track are most at risk.

Est. Repair Cost: £800–£1,500
Warning Signs:

Crunching on 2-3 gear change, Difficulty engaging gears when cold, Gearbox whine under load

What to Inspect:
  • Test gear changes through all ratios when cold.
  • Check for oil leaks from output shaft seals.

Immobiliser & Central Locking Failure

ModerateElectrics & Electronics

The immobiliser and central locking system can fail after prolonged shutdowns or when battery voltage is low. Moisture ingress into wiring under the dashboard accelerates connector corrosion.

Est. Repair Cost: £200–£500
Warning Signs:

Car won't start, Key fob not recognised, Central locking failure

What to Inspect:
  • Test key fob and immobiliser before purchase.
  • Check battery voltage and earth connections.
  • Leave car on trickle charger if stored for periods.

Alarm Sensor Failure (Cobra)

MinorElectrics & Electronics

The interior microwave sensors often fail or are over-sensitive, leading to the alarm going off randomly.

Est. Repair Cost: £200–£400
Warning Signs:

Alarm triggers randomly, Difficult to arm the car, LED diagnostic codes on dash

What to Inspect:
  • Test the alarm and check the diagnostic blink codes.
  • Ask if the interior sensors have been disabled or replaced.

Buying Tips for 2017 Lotus Elise S3

  • Inspect exposed manual gear linkage for dirt ingress or dried grease affecting shift feel
  • Verify supercharger belt tension and listen for blower bearing noise under light revs
  • On Sprint and Cup models, check exposed carbon fibre components for lacquer peeling or impact cracks
