Toyota agrees to $750 million settlement over diesel filters
The deal would end two class actions over faulty diesel particulate filters in about 264,000 HiLux, Prado and Fortuner vehicles. The Federal Court still has to approve it.
Toyota Australia has agreed to pay $750 million to settle two class actions over faulty diesel particulate filters (DPFs) in HiLux, Prado and Fortuner vehicles. The settlement still needs the approval of the Federal Court before any money is paid.
What the case was about
A DPF traps soot from a diesel engine's exhaust and burns it off from time to time. Owners of affected Toyotas complained of filters that clogged, white smoke from the exhaust, warning lights and repeated trips to the dealer.
In 2022 the Federal Court found that 264,170 HiLux, Prado and Fortuner vehicles with the 2.8-litre 1GD-FTV or 2.4-litre 2GD-FTV diesel engines, supplied between 1 October 2015 and 23 April 2020, were not of acceptable quality because of their DPF systems. Toyota appealed. The appeal court upheld the finding but cut the loss in value it had assessed per vehicle.
A second class action, filed in 2025, covered people who bought affected vehicles privately from their original owners between 24 April 2020 and 31 July 2025 and still own them. The settlement resolves both cases.
What owners get
The amount each owner receives has not been set. Legal costs and the litigation funder's share come out of the $750 million first, and the rest is to be divided among eligible group members. Owners who did not register with the class action can no longer join it. Anyone who thinks they are covered should contact the lawyers running the case.
What the affected years cost used
The affected vehicles were built from late 2015 to early 2020. They are still common on the used market. These are the median asking prices of diesel and petrol cars of those build years combined, for sale in the second week of November 2026, rounded to the nearest $500.
| Built | HiLux | Prado |
|---|---|---|
| 2016 | $30,000 | $37,000 |
| 2017 | $34,000 | $40,000 |
| 2018 | $37,000 | $46,000 |
| 2019 | $38,000 | $49,000 |
| 2020 | $41,000 | $51,500 |
Toyota has fixed the DPF problem on affected vehicles through a customer service program. If you are buying one, ask whether that work has been done and check the service history for repeated DPF repairs.
