Toyota Hilux (AN120) Problems by Year

The Toyota Hilux AN120, launched in 2016, cemented its reputation as the benchmark for utility pickup trucks in the UK, engineered specifically to handle the most arduous tasks demanded by the agricultural, construction, and commercial sectors. Built on a vastly improved, high-strength chassis, it provides superior toughness compared to its predecessors while incorporating more modern comfort features to suit its role as both a site-workhorse and a day-to-day transport solution for UK tradespeople. For the used buyer, it represents a highly specialized asset that requires a clear distinction between "lifestyle" trucks and those that have been used for genuine, heavy-duty commercial service. Reliability is deeply rooted in the Hilux DNA, yet the introduction of advanced emissions-control systems has made proper maintenance more critical than ever. The 2.4-litre and 2.8-litre D-4D engines are powerful and efficient, but their Diesel Particulate Filter (DPF) and "5th injector" regeneration systems are highly sensitive to the driving environment. These trucks are designed for work; they thrive on regular, longer-distance journeys that allow these systems to regenerate properly. Conversely, using a Hilux solely for short, stop-start trips can lead to significant DPF fouling, potentially resulting in power loss, warning lights, and the need for costly dealer intervention. When buying a used AN120 Hilux in the UK, prioritize a truck that has been serviced exclusively within the Toyota network, as this ensures all recall work—particularly regarding DPF software—has been completed. Prospective buyers should be wary of any vehicle that shows signs of heavy commercial use, such as distorted load beds, severe chassis corrosion from coastal or agricultural use, or evidence of repeated, heavy towing. A well-maintained Hilux AN120, free from the ravages of commercial neglect, remains perhaps the most dependable, capable, and enduring pickup truck available in the UK, provided it receives the professional, regular maintenance that its rugged design demands.
