2016 Hyundai I40 1.7L Diesel · RO16 WJK

The vehicle is currently roadworthy, but the maintenance history reveals a worsening trend regarding steering and suspension components. While the most recent test in March 2026 at 38,414 miles passed, the tester identified a front oil leak and play in both front inner track rod end ball joints. This indicates that the steering geometry is beginning to degrade, following previous failures related to the steering rack inner joints which were flagged in both 2022 and 2023. At 38,414 miles over ten years, this I40 has been significantly below average mileage, averaging approximately 3,800 miles per annum. This low usage often leads to the degradation of rubber components rather than mechanical wear from distance. The data shows a notable gap between July 2022 and July 2023, where the vehicle covered only 4,321 miles. The 2023 failure highlights a period of neglected basic upkeep, with tyres failing for insufficient tread and perishing rubber, suggesting the car may have sat stationary for long periods during these intervals. A buyer must prioritise inspecting the steering rack and front suspension assembly. The recurring nature of play found in the inner joints and track rod ends since 2022 suggests the steering system is nearing a comprehensive overhaul. The front oil leak noted in the 2026 test requires a physical inspection to determine if it is a minor seep or a sign of imminent seal failure due to age-related dry rot. Additionally, given the history of perished tyre cracking in 2023, a thorough check of the sidewalls on all tyres is essential to ensure they have not dried out despite the low mileage.
