Top issues to watch for

The most serious Fiat Coupe problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Structural corrosion around suspension mounting points
1751993–200140k–150k miles
MOT data shows this model fails at 131.8 times the fleet average for load-bearing structure failure within 30cm of suspension mounting points. The unibody construction uses relatively thin steel that corrodes from the inside out, particularly around the rear suspension pickup points and front subframe mounts. This is a structural safety issue that can lead to suspension detachment.
What happens if ignoredStructural failure around suspension mounts can cause wheel detachment or complete suspension collapse. Repair requires welding in new metal sections and is often uneconomical on cars of this age. The vehicle is unsafe to drive once structural integrity is compromised.

Dangerous
Brake system deterioration
1751993–200160k–120k miles
The brake calipers seize due to corrosion in the piston bores and guide pins, causing uneven braking force distribution. Combined with aging brake lines and deteriorated brake fluid, this creates a dangerous braking system degradation pattern.
What happens if ignoredSeized brake calipers can cause brake fade, uneven braking forces, or complete brake failure. The car may pull violently under braking or fail to stop within safe distances. Complete brake system overhaul typically required including calipers, discs, pads, and fluid system.

Major
Emissions system failure
1751993–2001100k–150k miles
The catalytic converters deteriorate due to age and contamination from oil consumption common on these engines. Lambda sensors also fail, causing incorrect air-fuel mixture and further catalyst damage.
What happens if ignoredFailed emissions systems cause MOT failure and potential engine damage from exhaust backpressure. Catalyst replacement is expensive and may reveal underlying engine wear issues causing the original failure. The car cannot be legally driven without valid MOT.

Major
General body corrosion
1751993–200160k–150k miles
0 times average for general structural corrosion. The steel bodywork corrodes extensively, particularly around door frames, sills, and rear wheel arches. This is typical of 1990s Italian construction with limited rustproofing.
What happens if ignoredExtensive body corrosion leads to structural weakness, water ingress, and ultimately renders the vehicle unsafe and uneconomical to repair. Many examples have been scrapped due to corrosion rather than mechanical failure.
