2021 Isuzu D-MAX DL20 1.9L Diesel · WA21 OSO

The vehicle is currently roadworthy, but the maintenance trend shows a recent shift toward developing mechanical defects. The most recent test on 22 July 2025 at 39,527 miles resulted in a failure due to an ineffective front windscreen wiper, a damaged side repeater, and an oil leak. While the vehicle passed after immediate repairs, the appearance of an axle seal leak indicates the start of component degradation that requires close monitoring. The mileage pattern remains consistent with a five-year-old vehicle, averaging approximately 7,900 miles per year. There is a 3,636-mile gap between the February 2024 test at 30,908 miles and the July 2024 test at 34,544 miles, followed by another 4,983-mile interval before the next inspection. This suggests low annual usage, which generally limits wear on the drivetrain and suspension components compared to high-mileage commercial use. A buyer must prioritise a physical inspection of the nearside front area regarding the oil leak. Although the tester noted the leak was not excessive in July 2025, axle seals can deteriorate rapidly if left unattended, potentially leading to significant fluid loss or gearbox damage. You should also verify the rear tyres, as the February 2024 record flagged both rear tyres as worn on the edge and near the legal limit, which often indicates an alignment issue or worn suspension bushes that may not been addressed.
