2013 Hyundai I40 1.7L Diesel · P31 GAG

The vehicle is currently roadworthy but the maintenance trend shows a clear shift toward deferred attention on aging components. While the most recent test in August 2025 at 100,516 miles was a pass, it revealed a significant accumulation of defects that were not present in previous years. The transition from a clean record in 2023 to multiple failures in 2024 indicates that the vehicle is now entering a phase where reactive repairs replace proactive maintenance. At 100,516 miles over 13 years, the Hyundai I40 averages approximately 7,700 miles per year, which is consistent with typical low-use patterns. The data shows consistent usage between 2022 and 2025, with a notable gap of 1,109 miles between the May 2024 and August 2025 tests. This relatively low annual mileage suggests that the mechanical issues observed are likely due to age-related degradation of rubber components and metal oxidation rather than high-frequency wear. A buyer must conduct a focused inspection of the rear suspension and braking system. The record consistently flags corrosion on the rear suspension arms and fractured coil springs, specifically the offside front spring which failed in May 2024. Although these were noted as not seriously weakened, the persistence of corrosion suggests the structural integrity of the lower subframe is deteriorating. The braking system also shows a history of pitted discs and a binding rear caliper, which implies the hydraulic components may be beginning to seize due to disuse. The condition of the tyres is another concern, as the tester noted cracking and perishing across all four corners in 2025. This indicates the vehicle has sat for long periods, causing the rubber to lose elasticity. Any purchaser should verify if all four tyres have been replaced since the last MOT, as perished rubber poses a safety risk regardless of the remaining tread depth.
