ISUZU D-MAX DL40 AUTO2023 · 1.9L DIESEL

The 2023 Isuzu D-Max DL40 Auto is currently roadworthy following its most recent MOT on 2026-03-30, but the maintenance trend shows a concerning pattern of recurring issues. Despite passing the test, the same fault—worn front brake discs—was flagged in both the March 2023 and March 2024 tests, indicating either persistent brake wear or a failure to address the problem promptly. The suspension issue with the offside rear lower shock absorber bush also reappeared, suggesting ongoing mechanical degradation. While the vehicle passed, the repetition of these faults implies that underlying wear may be accelerating rather than stabilising. The recorded mileage of 48,143 miles at the time of the March 2026 test suggests an average annual usage of approximately 16,000 miles over three years. This is notably high for a vehicle of this age, indicating frequent use or long-term commercial operation. The absence of MOT records prior to March 2023 makes it difficult to assess long-term maintenance consistency, but the high mileage combined with repeated component failures raises questions about the vehicle’s overall upkeep. If the previous owner neglected routine servicing, it could explain the accelerated wear seen in the brakes and suspension. Buyers should conduct a thorough in-person inspection focusing on the front brake system, including calipers and pads, as the repeated disc wear may point to underlying issues such as binding calipers or poor brake fluid maintenance. The suspension faults, particularly the worn shock absorber bush, warrant close examination of the rear suspension geometry and ride quality. Additionally, check for signs of corrosion on the chassis and wheel arches, as high mileage often correlates with increased exposure to road salt and moisture. Given the vehicle’s age and usage, a pre-purchase inspection by a specialist familiar with Isuzu models is strongly advised to assess the condition of the drivetrain and structural integrity.
