2018 Hyundai Tucson 1.7L Diesel · ML18 AEE

Recent electrical instability within the braking system defines the current mechanical state of this vehicle, specifically regarding a failure on 15 April 2026 involving the anti-lock braking system and electronic stability control. While the vehicle achieved a clean pass on 16 April 2026, the preceding failure was caused by excessively damaged wiring to the nearside rear ABS sensor. This indicates a specific vulnerability in the rear wheel arch wiring looms that required rectification to ensure the safety systems are fully operational. An accumulation of 74,451 miles over approximately eight years represents a typical usage profile of roughly 9,306 miles per year. This consistent mileage indicates the vehicle has been used regularly rather than sitting idle, meaning the drivetrain and engine components have likely remained in a steady state of operation. However, this level of use places the vehicle at a stage where wear-and-tear items, particularly suspension bushings and braking consumables, are reaching the end of their primary service life. Attention must be paid to the rear axle components, as previous records from March 2024 highlighted minor cracking in the nearside rear trailing arm bush. During a test drive, listen for knocks or thumps when traversing uneven road surfaces or speed bumps, as worn suspension bushes can lead to instability and accelerated tyre wear. The history of inner edge wear and stepping on the offside rear tyres suggests a potential misalignment or worn suspension geometry that should be verified through a physical inspection of the current tyre treads. Given the recent major failures related to the ABS and ESC systems, verify that no warning lamps illuminate on the instrument cluster upon ignition or during cornering. Ensure the brake pedal feel is consistent and that there is no unusual pulsation, which could indicate lingering issues with the ABS modulation or the quality of the wiring repair. A thorough check of the nearside rear wheel area is advised to ensure the repaired wiring is securely clipped and protected from road debris to prevent a recurrence of the previous failure.
