Isuzu has been a brand that has become renowned for its strong build quality since its introduction in the UK 30 years ago. While the Isuzu D-Max isn’t without its technical issues, it won our very first Pickup Reliability Survey in 2017.
Isuzu reliability history
The first Isuzu to be imported to the UK was the first-generation Isuzu Trooper in February 1987. The original model, which had already been on sale for six years elsewhere around the world, came with a 2.3-litre petrol engine which was slow, noisy and not the most reliable – the poor coolant flow would often lead to burned valves.
A year later, the popular 2.8-litre V6 diesel was introduced. Although the six-cylinder unit was even noisier, it proved to be much more reliable with more torque and horsepower (106hp).
However, it wasn’t until the second-generation Trooper was launched in 1991, did Isuzus become a much more common sight on UK roads. The new 3.1-litre diesel engine was introduced, which had few issues, although this was replaced by the 3.0TD in 1998. The later diesel was very prone to failing injector seals, injectors and turbo seals.
The Isuzu Trooper was taken off-sale in 2003 but, by this time, Isuzu had already commenced sales of the Rodeo pickup. While the Rodeo 3.0TD suffered from the same problems as the Trooper 3.0TD, the smaller 2.5TD was far more reliable and powered Isuzus for the next 13 years.
Isuzu D-Max reliability
In late 2017, we carried out our first Pickup Reliability Survey. Isuzu came out on top of the survey, with less than 0.17 Faults per Year, marginally ahead of the Toyota Hilux. A common problem, however, was the EGR valves – although most of these issues were covered by the warranty. Other common faults include the fuel filter and glow plugs.
