Toyota Hilux Mk7 / Mk8 (2005-2023) problems
Bodywork/ChassisHigh severity💬 Owner reports
The box-section chassis corrodes from the inside out: moisture sits trapped inside the enclosed sections and the factory coating is not up to UK salted roads, so perforation appears with little external warning. UK owners document MOT failures for chassis perforation near suspension points on trucks as young as seven years old, crossmember and fuel-tank-area corrosion on 2011-2012 trucks, and Toyota declining warranty on the grounds that it only covers painted body sections. Condition varies truck to truck, so each one must be judged on its own chassis.

Toyota Hilux service intervals: cambelt, chain and gearbox oil
An overdue cambelt is the most expensive thing a seller can fail to mention on a used Hilux. These are the figures UK specialists work to.
Timing belt (cambelt)Belt
3.0 D-4D, 3.0 D4D, 1KD-FTV
93,000 miles or 7 years, whichever comes first
Sources give 150,000 km (about 93,000 miles) for the 1KD-FTV, with the time element quoted as anything from 5-7 years to 10 years; the shorter 7-year figure is recorded. Many owners halve the mileage if the truck is used for heavy off-roading or towing. The dash usually displays a T-BELT warning light at the required mileage.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
Repair costs are typical UK ranges, not quotes. Actual cost depends on condition and garage.Data last verified: August 2026
Where this Toyota Hilux fault data comes from
If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Toyota Hilux owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Toyota Hilux goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
