Top issues to watch for

The most serious Alfa Romeo Gt problems ranked by severity. We track 6 known issues — here are the ones you need to know about first.

Dangerous
Structural corrosion around suspension mounting points
2003–201060k–200k miles
The GT suffers from severe structural corrosion around suspension mounting points and subframe attachment areas, particularly affecting the rear suspension mounting points and front subframe mounting areas. MOT data shows this model fails structural integrity tests at 842.4x the fleet average, with the problem worsening significantly after 60,000 miles. This is a known weakness shared with the 147/156 platform, where inadequate protection of structural steel leads to corrosion that compromises the mounting point integrity.
What happens if ignoredStructural failure around suspension mounting points creates an immediate safety risk and MOT failure. Repair requires cutting out corroded sections and welding in new metal, typically costing £800-£2,000 depending on extent. In severe cases the car may be beyond economical repair.

Major
DPF blockage and emissions failure (1.9 JTD)
1.9 JTD2003–201080k–150k miles
The 1.9 JTD diesel engine suffers from diesel particulate filter (DPF) blockage, with MOT data showing smoke opacity failures at The DPF system requires regular high-speed driving to burn off accumulated soot. Cars used for short journeys or urban driving experience chronic blockage, leading to limp mode, warning lights, and eventual emissions test failure.
What happens if ignoredComplete DPF blockage triggers limp mode and MOT failure. Professional DPF cleaning costs £200-£400. DPF replacement costs £800-£1,500. The car may be undriveable until repaired and will not pass MOT emissions tests.

Suspension component corrosion
2003–201040k–200k miles
GT models suffer from accelerated corrosion of suspension components, with MOT data showing failures at 842.4x the fleet average. Lower wishbones, anti-roll bar links, and suspension arms are particularly affected. The Italian origin and inadequate corrosion protection leads to premature failure of steel suspension components, especially in UK salt-road conditions.
What happens if ignoredCorroded suspension components affect handling safety and cause MOT failure. Individual component replacement typically costs £100-£300 per side. Multiple components may need replacement simultaneously, with total costs reaching £800-£1,200 for comprehensive suspension refresh.

General body corrosion
2003–201060k–200k miles
The GT suffers from widespread body corrosion issues typical of Italian cars from this era. Poor factory corrosion protection and thin steel panels make this model particularly susceptible to UK road salt and coastal conditions.
What happens if ignoredExtensive body corrosion leads to MOT failure and structural weakness. Cosmetic rust repair costs £300-£800 per panel. Structural repairs involving cutting and welding cost £800-£2,000 depending on extent. Advanced corrosion may render the car beyond economical repair.
