All Known Issues

1.4 MultiAir Actuator Failure

SeriousEngine

The "MultiAir" brick can fail if oil changes are missed or the wrong viscosity is used. This is a common and expensive failure.

Est. Repair Cost: £800–£1,500

Parts availability and escalating costs

ModerateBodywork & Rust

With production ceased and the Mazda-Fiat partnership ended, 124 Spider-specific parts are becoming scarce and expensive. Body panels (especially aluminium items), windscreens, key fobs and even the bonnet pedestrian-safety actuators can be on backorder for months. Some cars have been written off due to parts being unavailable for minor accident repairs.

Est. Repair Cost: £200–£10,000+

MultiAir oil drain-back when sitting unused

ModerateEngine

If the 1.4 MultiAir engine sits unused for several months, oil can drain from the hydraulic MultiAir unit ("the brick"), affecting the valve train and preventing the engine from starting due to lack of compression. The fix is usually to crank it until the unit re-primes, but repeated occurrences can damage the unit.

Est. Repair Cost: £0–£500

Buying Tips for 2016 Fiat 124 Spider

  • The MultiAir engine is extremely sensitive to oil quality; a full, on-time service history is non-negotiable.
  • Check the convertible roof operation; it should be swift and lock securely without any excessive wind noise.
