Isuzu D-Max (Mk3) Common Problems & Reliability
The third-generation Isuzu D-Max (2021-onwards) represents a massive leap forward for the brand, transforming from a pure agricultural workhorse into a highly refined, tech-laden pickup capable of challenging the Ford Ranger. It boasts a completely redesigned cabin, significantly improved ride quality, and a maximum five-star Euro NCAP safety rating, a rarity in the pickup class. In the UK, it retains its legendary 3.5-tonne towing capacity and 1-tonne payload, making it a favorite among farmers and tradespeople, while the luxurious V-Cross models appeal to lifestyle buyers. Reliability remains its trump card, powered by a heavily revised, unburstable 1.9-litre diesel engine. It is the perfect choice for buyers needing a tough, dependable commercial vehicle that doesn't sacrifice modern comforts.
