2010 Citroen DS3 1.6L Diesel · PF60 PXT

The vehicle presents a concerning history of structural degradation that has only recently been addressed. In the December 2025 test at 68,513 miles, the car failed due to significant structural weaknesses in the outer sills, which compromised the strength of the seat belt anchorages. While the vehicle passed just three days later at 68,516 miles, the record notes the full underbody was corroded and required both sills to be undersealed. This indicates a reactive repair approach to advanced rust rather than preventative maintenance, suggesting the structural integrity of the chassis has been under constant threat. At 16 years old with 68,516 miles, this DS3 has covered an average of approximately 4,282 miles per year. This low usage often correlates with the accelerated corrosion issues seen in the record, as vehicles that sit stationary are more prone to moisture-related rust. The 2024 test at 64,216 miles revealed a major exhaust leak and binding rear service brakes, while the 2023 test at 60,399 miles flagged a corroded rear coil spring and a front subframe. The recurring nature of brake-related failures, including binding and fluctuating performance, suggests inconsistent braking system maintenance despite the low mileage. A buyer must scrutinize the quality of the recent undersealing to ensure the sill repairs are structurally sound rather than merely cosmetic. Given the heavy corrosion noted on the subframes and suspension components across multiple years tests, the risk of future mechanical failure remains high. The transition from a minor exhaust leak in 2023 to a major structural failure in 2025 shows a vehicle reaching a point where age-related decay is outpacing its low mileage.
