2016 Toyota Hilux 2.4L Diesel · AE66 NPP

The most recent MOT on 16 January 2026 was a pass, albeit with a minor fault for excessively rapid flashing of the direction indicators and advisories that both front tyres are worn close to the legal limit. Earlier in the series there have been two major failures – a deep cut on the off‑side front tyre and a nail in the near‑side rear tyre in September 2023, and a serious brake‑lever travel deficiency together with a parking‑brake efficiency below 50 % in September 2022. Although the vehicle has cleared its last two tests, the pattern shows intermittent serious defects rather than a consistently improving maintenance record, suggesting that recent attention has remedied the most critical faults but that tyre wear remains a pressing issue. At ten years old the Hilux has logged 82 157 mi, which works out to roughly 8 200 mi per annum – a usage rate that sits squarely within the normal band for a light‑commercial vehicle of this age. There are no obvious mileage gaps that would indicate long periods of storage, nor any spikes that would point to unusually heavy duty use. Consequently the wear on consumables such as tyres, brakes and suspension components should be proportional to the mileage rather than to any extreme duty cycle. The tyre situation demands immediate scrutiny. Both front tyres are flagged as close to the legal tread limit and the off‑side front tyre previously suffered a cut that reached the ply, while the near‑side rear tyre carried an unrepaired nail in the shoulder. On a test drive the driver should feel any vibration, pulsation or side‑to‑side wobble that can arise from uneven tread or a compromised sidewall, and should listen for thumping that may indicate a bulge or internal damage. Replacement of the front set is advisable before the tread drops below 1.6 mm, and the rear tyre should be examined for structural integrity; if the nail‑induced damage cannot be safely repaired, a new rear tyre will be required. The earlier brake‑lever travel fault and the parking‑brake efficiency failure mean the braking system should be inspected thoroughly – check the condition of the master cylinder, hand‑brake cable, and the wear of pads and discs for uneven scoring or rust‑induced glazing. Any soft or spongy pedal feel, excessive pedal travel, or a parking brake that fails to hold the vehicle on a gradient are red flags that further remedial work may be needed. Beyond the tyre and brake concerns, the Hilux’s age calls for a series of calendar‑based checks. Verify that the battery terminals are clean and that the charge holds, as a ten‑year‑old 12 V unit can suffer from sulphation even with modest use. Inspect the suspension bushes, ball joints and coil springs for cracking, corrosion or excessive play, which can manifest as clunking noises over bumps. Examine all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – for proper levels and signs of contamination; fluids older than two years should be replaced regardless of mileage. Finally, confirm that service stamps in the logbook correspond with the MOT dates and that any recommended time‑based services, such as timing‑belt or chain inspection, have been performed, as these are critical to the long‑term reliability of a vehicle that has seen a decade of service.
