2007 Alfa Romeo 159 2.4L Diesel · RB03 RON

Structural integrity concerns regarding the rear sills and subframe represent the most significant mechanical risk identified in this vehicle's history. While the 2021-11-03 test resulted in a pass with no defects recorded, the 2020-10-21 failure highlighted major corrosion issues on both the nearside and offside rear suspension component mountings within the outer sill areas. This failure was accompanied by advisories regarding corrosion on the rear subframe and rear suspension arms. Although the record shows a return to a clean status in the most recent tests, the previous presence of significant structural corrosion in the sills and subframe suggests a history of degradation in the chassis components that warrants close inspection. The vehicle has covered 137,523 miles over its nineteen-year lifespan, which equates to an average annual accumulation of approximately 7,238 miles. This usage pattern is consistent with typical age-related mileage for a vehicle of this type. Such moderate, steady usage suggests that while the drivetrain and major mechanical components have been subjected to regular operation, they have not been subjected to the high-frequency wear associated with heavy long-distance commuting. However, the consistent mileage profile does not mitigate the risks posed by the previously recorded structural corrosion, which is often a function of environmental exposure rather than mileage alone. A prospective buyer should pay particular attention to the rear of the vehicle during a test drive, specifically focusing on the condition of the chassis and suspension. Given the 2020 failures for excessive corrosion on the outer sill suspension mountings, it is essential to inspect the underside for any signs of active, spreading rust or recent remedial welding. During the drive, listen for any knocking, clunking, or irregular thudding sounds coming from the rear suspension, which could indicate issues with the suspension arms or bushes that were previously flagged for corrosion. Any unevenness in the ride quality or a tendency for the rear of the car to feel unsettled over bumps could be symptomatic of compromised mounting points or worn suspension components. Further scrutiny should be applied to the braking system and tyres, following the history of broken coil springs, thin brake pads, and tyre failures. While these specific items were addressed to pass subsequent tests, the 2016 failures for a broken nearside rear coil spring and insufficient brake pad thickness indicate that consumable and suspension components have reached their service limits in the past. On a test drive, check for any pedal judder or pulling to one side under braking, which may indicate binding calipers or uneven disc wear. Additionally, ensure the tyres show even wear across the tread, as previous advisories for inner tyre wear suggest potential issues with wheel alignment or suspension geometry.
