Why some Fiat engines score below 68/100
Fiat's engine history is a European small-car story: brilliant packaging with sometimes questionable durability. The 0.9 TwinAir and certain diesel applications represent the bulk of the reliability complaints.
The pattern
Fiat's problems centre on the 0.9 TwinAir — oil consumption and its MultiAir valve actuator — and on some older JTD/MultiJet diesels. The 1.4 MultiAir turbo is better than its early reputation, and the naturally aspirated FIRE engines and the FireFly 1.0 mild hybrid are significantly more reliable.

What to buy instead
Not all Fiat engines are problematic. These score well:
- 1.6 E.torQ — 89/100 (BEST)
- FIRE 1.2 8V/16V — 88/100 (BEST)
- 3.0 JTD/MJT — 83/100 (BUY)
