Italy's most thrilling answer to the 3 Series
The Giulia is Alfa Romeo's compact luxury sport sedan, competing with the BMW 3 Series, Audi A4, and Mercedes C-Class. It appeals to enthusiasts who prioritise driving engagement and Italian flair over outright practicality. Heavy depreciation makes it a compelling used buy for those willing to accept the reliability gamble.
We track 9 known issues across the Alfa Romeo Giulia range, with 3 classified as significant. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.
Found a Alfa Romeo Giulia? Enter the reg to see which of our 9 known issues apply to that exact car, plus full MOT history and mileage checks.
952 (2016–2022) — Petrol options included the 2.0 Turbo, with 2.2 MultiJet on the diesel side. We track 8 known issues on this generation, with 3 classified as significant. The most significant concern is Suspension component premature wear (£300–£600 to address).
Quadrifoglio (2016–2022) — Engine options included the 2.9 V6 Twin Turbo. We track 3 known issues on this generation, with 1 classified as significant. The most significant concern is Fuel pump failures (£400–£700 to address).
Suspension pins, bushes and joints on 952 Giulias show accelerated wear patterns compared to equivalent BMW or Audi models. The issue is most pronounced on 2.0 petrol variants and appears to be design-related rather than manufacturing defect. Later production cars from 2020 onwards show marginal improvement but the fundamental issue persists.
Worn suspension components compromise handling, braking stability and tyre life. Failed bushes can allow suspension geometry to change unpredictably under braking or cornering loads. Repair typically involves replacing multiple components due to the interconnected nature of suspension wear on this platform.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The 2.2 MultiJet diesel engine experiences DPF blockage and regeneration failures, particularly on cars used for short journeys or urban driving. The DPF warning light illuminates frequently and the system requires manual regeneration cycles. Complete DPF replacement is expensive and some owners resort to illegal DPF removal which fails MOT emissions testing.
Failed DPF systems require expensive replacement or professional cleaning. Blocked DPF filters can damage turbochargers due to increased exhaust backpressure. Cars with removed DPF systems will fail MOT emissions testing and cannot be legally driven on UK roads.
Ask about the car's typical usage — short urban journeys prevent DPF regeneration. Check for DPF warning lights and ask about any previous regeneration issues. A forced regeneration at a garage costs far less than a DPF replacement.
NHTSA complaints document in-tank fuel pump failures causing sudden power loss and stalling. The issue affects both petrol variants and appears related to fuel pump module design rather than contamination. Failed pumps can cause dangerous stalling in traffic with limited warning signs before complete failure.
Complete fuel pump failure causes immediate engine shutdown and can occur without warning during driving. This creates significant safety risks in traffic situations. Replacement requires tank removal and is labour-intensive. Some failures may be covered under extended warranties or recalls in certain markets.
Check for fuel smells around the engine bay and underneath the car. Look for staining or wetness around fuel lines and connections. Injector issues may cause rough running or misfires that are most noticeable at idle.
Common triggers include lambda sensor faults, EGR valve carbon buildup on diesels, and software glitches in the engine control module. While often not immediately serious, the underlying faults can develop into more expensive repairs if ignored.
Most MIL triggers on this model are emissions-related sensor faults rather than serious engine damage. However, driving with active faults can damage catalytic converters or DPF systems on diesels. Diagnostic investigation typically reveals lambda sensors, EGR valves, or software updates required.
Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.
The issue affects both front and rear brakes and appears related to brake compound specification rather than driver abuse. Some early production cars show disc scoring and pad degradation at under 20,000 miles.
Premature brake wear increases running costs and may compromise braking performance if not addressed promptly. Scored discs typically require replacement rather than skimming due to the depth of surface damage. Budget for more frequent brake component replacement than typical for this vehicle class.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.

Based on 30k real DVSA MOT tests, the Alfa Romeo Giulia fails more often than average on several items. The biggest outlier is headlight fault at 28x the fleet average, followed by tyre cords visible or damaged (10x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Alfa Romeo Giulia MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.
The bigger-ticket items to budget for include automatic transmission fluid (£200–£300).

The Alfa Romeo Giulia is a solid choice on the used market, though not without its quirks. The issues we track are well-understood and largely avoidable if you know what to look for. A thorough inspection and complete service history go a long way. 2021 onwards are the most reliable, with recalls tailing off and build quality much improved. The 2023-2025 models benefit from years of refinement and are the safest used buys. Avoid 2017-2018 first-year production cars.
