Toyota HiLux Years to Avoid Australia: The Used Buyer’s Guide

The Toyota HiLux has earned an almost mythical reputation in Australia. We see them on construction sites, farms, highways, beaches and remote tracks where lesser vehicles might think twice before venturing. Yet being a HiLux does not automatically make every model year bulletproof.

If we're shopping second-hand, knowing the Toyota HiLux years to avoid in Australia can save us from expensive repairs, frustrating warning lights and potentially thousands of dollars in unexpected maintenance.

The biggest period to approach carefully is the 2015–2019 diesel HiLux range, particularly early N80 models equipped with Toyota's 2.4-litre 2GD-FTV or 2.8-litre 1GD-FTV engines. Certain vehicles acquired as late as 23 April 2020 were also included in the Australian DPF class-action period.

That doesn't mean every HiLux from these years is bad. Far from it. Many have travelled hundreds of thousands of kilometres without major trouble. But when we're buying used, these years deserve considerably more investigation than a HiLux with a spotless history from a less troublesome production period.

Let's break it all down.

Toyota HiLux Years to Avoid Australia: Quick Answer

If we want the short answer, these are the periods we'd inspect most carefully:

The most important distinction is that the well-documented Australian DPF issue doesn't line up perfectly with model years.

The Federal Court notice relating to Toyota's DPF class action states that relevant HiLux, Prado and Fortuner vehicles fitted with 1GD-FTV or 2GD-FTV diesel engines and acquired between 1 October 2015 and 23 April 2020 were affected by a defective DPF system.

So rather than blindly rejecting every 2015–2020 HiLux, we should identify the engine, production date, service history and whether the required DPF repair or updates have been completed.

Why Some Toyota HiLux Years Are More Problematic Than Others

The HiLux itself isn't fundamentally unreliable.

The problem is that different generations introduced different engines, emissions equipment, electronics and drivetrain components.

A 2008 HiLux and a 2018 HiLux might wear the same badge, but mechanically they're very different animals.

The areas that matter most include:

• diesel particulate filter design;
• injector condition;
• fuel-system reliability;
• air filtration;
• previous off-road use;
• towing history;
• servicing;
• completed recalls;
• modifications;
• kilometres travelled.

That's why we wouldn't buy a HiLux simply because someone tells us, "Mate, they're indestructible."

Even a hammer eventually breaks if someone spends twenty years hitting rocks with it.

2015–2018 Toyota HiLux: The Years We'd Inspect Most Carefully

Why Early N80 HiLux Models Matter

Toyota introduced the N80-generation HiLux in Australia during 2015.

Among other changes, the new-generation diesel models brought the 2.4-litre 2GD-FTV and 2.8-litre 1GD-FTV engines.

Unfortunately, the early diesel particulate filter system became one of the most widely discussed problems associated with this generation.

Used-car guidance from Carsales specifically highlights DPF problems affecting 2.8-litre diesel HiLux models built from roughly 2015–2018, particularly vehicles subjected to frequent short journeys where the exhaust doesn't get sufficiently hot for successful filter regeneration.

The Infamous HiLux DPF Problem

A diesel particulate filter traps soot from the exhaust.

Once the filter reaches a certain soot load, the vehicle performs a regeneration cycle, raising exhaust temperatures sufficiently to burn accumulated particles.

At least, that's how it's supposed to work.

Some early N80 HiLux vehicles struggled with this process.

Possible symptoms included:

• excessive white smoke;
• DPF warning lights;
• repeated regeneration cycles;
• increased fuel consumption;
• reduced performance;
• limp-home mode;
• clogged particulate filters.

Toyota introduced an ECU reprogramming campaign for certain early HiLux models and subsequently introduced a manual DPF regeneration switch. Australian Car.Reviews reports that the switch appeared in August 2018, with Toyota later offering retrofits to earlier vehicles.

Why Short Trips Can Make DPF Problems Worse

DPFs generally prefer sustained operating temperatures.

If a diesel ute spends most of its life doing five-minute school runs, crawling through city traffic or repeatedly stopping and starting, regeneration conditions may be harder to achieve.

That's why an 80,000km city-driven HiLux isn't automatically a safer purchase than a 160,000km vehicle that spent its life travelling long highway distances.

Driving history matters almost as much as kilometres.

What the Australian Toyota DPF Class Action Tells Us

This is where speculation ends and documented history begins.

Toyota Australia's Federal Court notice states that relevant Toyota HiLux, Prado and Fortuner vehicles equipped with 1GD-FTV or 2GD-FTV diesel engines acquired between 1 October 2015 and 23 April 2020 were not of acceptable quality when initially supplied because of their defective DPF systems.

The litigation reached the High Court of Australia, which dealt with how damages relating to the reduction in vehicle value should be calculated.

For us as used buyers, however, the practical takeaway is simpler:

A 2015–2019 diesel HiLux deserves careful DPF investigation before purchase.

An early-2020 vehicle may also warrant the same investigation depending on its engine, supply date and history.

That is far stronger evidence than simply saying a certain model year received bad online reviews.

Is the 2015 Toyota HiLux a Year to Avoid?

We'd place a 2015 diesel N80 HiLux near the top of the caution list.

Being the introduction year of a new generation means we're dealing with an early version of the new drivetrain and emissions system.

That doesn't mean we should immediately walk away.

A 2015 HiLux with:

• complete Toyota or specialist service records;
• evidence of DPF updates;
• no warning lights;
• healthy regeneration behaviour;
• clean diagnostics;
• no suspicious exhaust smoke;
• excellent cold-start behaviour;

could still be a perfectly sensible ute.

But we'd never buy one without a comprehensive pre-purchase inspection.

Is the 2016 Toyota HiLux a Bad Year?

The 2016 HiLux falls squarely inside the early N80 period we'd scrutinise.

DPF condition remains the biggest concern on diesel examples.

Some early N80 vehicles have also been associated with tailshaft clunk complaints and sensitivity to dust contamination around the mass-airflow sensing system. Australian Car.Reviews documents both concerns among early eighth-generation HiLux vehicles.

For anyone intending to use the ute heavily in dusty regional Australia, examining the air intake and filtration system becomes particularly important.

What We'd Check on a 2016 HiLux

Before purchasing one, we'd inspect:

1. DPF regeneration history.
2. Stored ECU fault codes.
3. Injector behaviour.
4. Air-filter housing.
5. MAF sensor condition.
6. Tailshaft movement or clunks.
7. Four-wheel-drive operation.
8. Service records.
9. Underbody damage.
10. Evidence of heavy towing.

A well-maintained 2016 isn't automatically problematic.

An unknown-history 2016 diesel, however, isn't something we'd buy purely because the odometer looks attractive.

2017 Toyota HiLux Problems to Watch

A 2017 HiLux deserves similar caution.

Apart from DPF considerations, certain HiLux vehicles were subject to specific recall campaigns.

For example, Toyota recalled certain 2015–2017 HiLux 4x4 and Hi-Rider vehicles fitted with a Toyota genuine auxiliary battery kit because vibration on rough roads could damage mounting points and potentially affect nearby wiring.

This doesn't mean all 2017 HiLux models were unsafe.

It illustrates something far more useful for used buyers:

Don't judge recalls by year alone. Check the VIN.

Toyota Australia provides an online VIN recall checker, and outstanding recall repairs are performed free of charge.

Should We Avoid the 2018 Toyota HiLux?

The 2018 HiLux sits at an interesting turning point.

Toyota HiLux Models by Year Australia: Complete Generation Guide

Early vehicles remain part of the problematic DPF period, but Toyota progressively introduced improvements.

A manual DPF regeneration switch was introduced during 2018, helping drivers initiate regeneration when required.

For that reason, we'd generally prefer a later-production 2018 vehicle with documented updates over an untouched early-production example.

But condition still wins.

A neglected late-2018 HiLux can be far worse than a meticulously maintained 2016.

Is the 2019 Toyota HiLux Safe to Buy?

The 2019 model year is where the picture starts improving, but we wouldn't completely drop our guard.

Vehicles acquired during 2019 still fall inside the DPF class-action period if fitted with the relevant engines.

There was also a separate fuel-pump recall affecting certain petrol HiLux models.

Toyota Australia's recall information lists TGN121 HiLux vehicles produced between September 2017 and February 2019, among other production ranges, where the low-pressure fuel pump could potentially stop operating and cause rough running, failure to start or engine stalling.

Again, that's a VIN-specific issue rather than a reason to blacklist every 2019 HiLux.

2019 HiLux Buying Strategy

We'd happily consider one if:

• the VIN shows recall work is complete;
• DPF behaviour is normal;
• service history is comprehensive;
• diagnostics show no worrying codes;
• the engine starts cleanly;
• there is no suspicious smoke;
• the previous owner can explain how the vehicle was used.

What About the 2020 Toyota HiLux?

For many second-hand buyers, 2020 represents an important dividing line.

Toyota launched a substantially upgraded HiLux in August 2020.

The revised 2.8-litre 1GD-FTV turbo-diesel received numerous mechanical changes, with output increasing to 150kW and as much as 500Nm on automatic models. Toyota also introduced revisions to the common-rail injection system, turbocharger and other components.

This makes the later 2020-onward HiLux particularly interesting on the second-hand market.

However, we need to distinguish an early 2020 vehicle from the upgraded version introduced later that year.

Why Build Date Matters

Two vehicles advertised as "2020 Toyota HiLux" might not be identical mechanically.

One may have been built before the major update.

The other may be the later upgraded vehicle.

So check the compliance plate, build date and specifications rather than relying purely on the year shown in the advertisement.

2018–2020 Brake Booster Recall

Certain Toyota HiLux and Fortuner vehicles from 2018–2020 were recalled in Australia because the brake booster could have been manufactured incorrectly.

According to the Australian government's Vehicle Recalls database, the issue could lead to a loss of braking assistance under repeated brake operation, potentially increasing stopping distance. The campaign affected 23,957 HiLux and Fortuner vehicles combined.

Does that mean we should avoid every 2018–2020 HiLux?

No.

It means we should verify whether the specific VIN was affected and, if so, whether the recall repair was completed.

2015–2021 Rear Licence Plate Bracket Recall

Another example of why "recall" doesn't necessarily equal "bad model year" is a campaign covering a large number of HiLux vehicles from 2015–2021.

The Australian recall database lists 156,838 vehicles in a campaign concerning the rear licence-plate bracket, which could crack after vibration on rough roads.

That's obviously something owners should rectify.

But it isn't comparable to a major powertrain reliability problem.

This distinction is important when researching Toyota HiLux years to avoid in Australia.

Should We Avoid the Older N70 HiLux?

The N70 generation, sold broadly between 2005 and 2015, remains immensely popular.

Its simplicity is part of the attraction.

But these vehicles are getting old.

Even an excellent 2010 HiLux is now old enough that maintenance history becomes far more important than the reputation Toyota built around it.

3.0-Litre 1KD-FTV Diesel Considerations

Older 3.0-litre turbo-diesel models deserve careful inspection of the fuel and injection system.

Used-vehicle guidance commonly identifies injector condition and injector sealing as areas to investigate on ageing diesel HiLux models.

Rather than calling one specific N70 year "bad," we'd treat the entire older diesel population as condition-sensitive.

Age Changes the Reliability Equation

At 15 or 20 years old, failures can result from:

• worn suspension;
• deteriorated bushes;
• leaking seals;
• old cooling-system components;
• tired injectors;
• neglected transmission fluid;
• corrosion;
• hard off-road use;
• repeated heavy towing.

When we're buying an N70, the previous owner is often more important than the badge on the grille.

The Hidden Problem: Abused Toyota HiLux Models

Here's something model-year guides sometimes miss.

A technically reliable HiLux can still be a horrible purchase.

Why?

Because these vehicles often work for a living.

A HiLux may have spent ten years:

• carrying tools;
• pulling trailers;
• crossing construction sites;
• towing caravans;
• driving through water;
• travelling corrugated roads;
• working on mines;
• running along beaches.

The odometer only tells us distance.

It doesn't tell us how difficult those kilometres were.

How to Spot a Hard-Worked HiLux

Inspect the Underbody

Look underneath.

Fresh black paint can sometimes hide a hard life rather than reveal careful ownership.

We'd look for:

• dented bash plates;
• bent crossmembers;
• crushed exhaust components;
• leaking differentials;
• damaged CV boots;
• rust;
• chassis damage;
• excessive mud packed into cavities.

Look at the Towbar

Heavy wear around the towbar can hint at regular towing.

That's not automatically bad—HiLux models are designed to work—but heavy towing makes proper servicing more important.

Examine the Tray

A badly dented tray tells a story.

So does a pristine liner covering scratched or corroded metal underneath.

How to Check a Used HiLux DPF Before Buying

If we're considering a 2015–2020 diesel, this is one area we'd never ignore.

Ask the seller:

• Has the DPF ever been replaced?
• Has it needed forced regeneration?
• Was Toyota's repair performed?
• Have DPF warning lights appeared?
• Was the vehicle mostly driven in town or on highways?
• Has the ECU been modified?
• Has the DPF been deleted?

Then have a qualified mechanic perform an electronic scan.

The scan may reveal information that a polished dashboard and freshly detailed engine bay can't hide.

Are Toyota Hilux Reliable? Reliability, Problems and Lifespan Explained

Never Assume Low Kilometres Means Better

A low-kilometre diesel HiLux looks irresistible on paper.

But consider two hypothetical vehicles.

HiLux A

90,000km.

Mostly driven five kilometres each way through suburban traffic.

HiLux B

170,000km.

Mostly highway commuting with documented servicing.

Which is better?

We can't determine that from kilometres alone.

For a diesel relying on successful DPF regeneration, operating conditions matter considerably.

That's why we're interested in how the kilometres accumulated, not just how many appear on the odometer.

Are 2020–2024 Toyota HiLux Models Better?

For buyers wanting an N80 without concentrating on the earliest DPF-era vehicles, the later models can be particularly appealing.

The substantial late-2020 update increased power from the 2.8-litre engine to 150kW and automatic torque to 500Nm while introducing multiple engine changes.

That doesn't make 2020–2024 vehicles immune to every problem.

No vehicle is.

It simply places them outside the earliest and most controversial portion of the N80 diesel story.

We'd still check:

• VIN recalls;
• service intervals;
• DPF condition;
• towing history;
• modifications;
• underbody condition;
• injector data;
• transmission operation.

What About 2025 and 2026 HiLux Models?

They're too new for us to make a meaningful long-term reliability judgement.

Toyota has introduced the latest HiLux generation in Australia, retaining the 2.8-litre turbo-diesel across core grades while also expanding electrified technology.

There has already been a specific Australian recall involving certain 2025–2026 HiLux vehicles equipped with Toyota Genuine bull bars or nudge bars with light bars.

The recall concerns installation of an electrical connection associated with the electric power steering system. Approximately 13,390 vehicles were listed in the Australian campaign.

We wouldn't interpret that as evidence that the entire 2025 or 2026 HiLux range should be avoided.

It's a specific recall affecting particular vehicles and equipment combinations.

Which Toyota HiLux Years Would We Be Most Cautious About?

If our goal is minimising risk while buying a used diesel HiLux in Australia, we'd put the strongest inspection emphasis on:

2015, 2016, 2017 and early 2018 N80 diesels.

We'd also carefully investigate:

late 2018, 2019 and early-2020 diesel examples.

Why?

Because that period overlaps heavily with Toyota's documented Australian DPF history.

But we'd never reject an otherwise excellent vehicle solely because of the number printed on its compliance plate.

A Good 2017 Can Beat a Bad 2022

This might be the most important point in our guide.

Suppose we find a 2017 HiLux with:

• one owner;
• every service receipt;
• completed Toyota campaigns;
• corrected DPF system;
• highway-heavy use;
• no modifications;
• perfect diagnostics.

Beside it sits a 2022 HiLux that has:

• missing service records;
• a questionable ECU tune;
• beach-driving corrosion;
• suspension modifications;
• evidence of hard towing.

Which one should we prefer?

The newer vehicle isn't automatically better.

Year helps us identify risk.

Condition tells us what we're actually buying.

Pre-Purchase Checklist for an Australian Toyota HiLux

Before handing over our money, we'd complete this checklist:

1. Verify the VIN.
2. Check Toyota's recall database.
3. Run a PPSR check.
4. Confirm engine type.
5. Check build and compliance dates.
6. Review complete service records.
7. Perform a cold start.
8. Scan the ECU.
9. Check DPF data on diesel models.
10. Listen for injector abnormalities.
11. Test the automatic or manual transmission.
12. Engage four-wheel drive.
13. Test low range.
14. Check the rear differential lock where fitted.
15. Inspect chassis and underbody.
16. Look for beach-use corrosion.
17. Inspect suspension modifications.
18. Examine the towbar.
19. Check tyres for uneven wear.
20. Pay for an independent mechanical inspection.

A few hundred dollars spent before purchase can potentially prevent a repair bill measured in thousands.

Should You Buy a Toyota HiLux With 200,000km?

Potentially, yes.

A well-maintained HiLux can travel very high kilometres.

The number itself wouldn't scare us nearly as much as poor maintenance.

We'd rather buy a properly serviced 200,000km vehicle than a neglected 100,000km example with no records.

High kilometres become far less concerning when accompanied by:

• documented servicing;
• highway use;
• good compression;
• clean diagnostics;
• healthy injectors;
• proper transmission maintenance;
• no major chassis damage.

Toyota HiLux Years to Avoid Australia: Final Thoughts

Calling any Toyota HiLux year completely "bad" oversimplifies the story.

The clearest Australian trouble period involves early N80 diesel HiLux models introduced from 2015, particularly vehicles built and sold through the latter half of the 2010s.

Toyota's Australian DPF litigation provides particularly strong evidence for caution around relevant 1GD-FTV and 2GD-FTV diesel vehicles acquired between 1 October 2015 and 23 April 2020.

If we're trying to reduce risk, the 2015–2018 diesel HiLux deserves our closest inspection, while 2019 and early-2020 vehicles still warrant careful verification.

Later N80 models—particularly following Toyota's significant late-2020 mechanical update—can make attractive alternatives when their service history and condition are good.

But remember the golden rule of buying a used HiLux:

We're buying the previous owner's maintenance history as much as we're buying a Toyota.

A carefully maintained HiLux from a supposedly troublesome year can provide years of dependable service. A neglected example from a supposedly excellent year can become a financial black hole.

Check the VIN. Read the service book. Scan the electronics. Inspect underneath.

And never let Toyota's legendary reliability reputation replace a proper pre-purchase inspection.

FAQs About Toyota HiLux Years to Avoid in Australia

1. What Toyota HiLux years should I avoid in Australia?

We'd exercise the most caution with 2015–2018 N80 diesel models, followed by 2019 and some early-2020 examples. Relevant 1GD-FTV and 2GD-FTV vehicles acquired between October 2015 and April 2020 were involved in Australia's documented DPF class-action period. A good service history and evidence of completed repairs can significantly change the picture.

2. Which Toyota HiLux years had DPF problems?

The issue is most strongly associated with early N80 diesel vehicles introduced from 2015. The Australian DPF class action covers relevant HiLux, Prado and Fortuner diesels acquired between 1 October 2015 and 23 April 2020. Early 2015–2018 HiLux diesels are therefore especially worth checking carefully.

3. Is a 2018 Toyota HiLux worth buying?

Yes, potentially. A properly maintained 2018 HiLux with completed DPF-related updates can still be a good vehicle. Later 2018 production is particularly interesting because Toyota introduced a manual DPF regeneration switch during that year. Always verify the individual vehicle rather than relying solely on its model year.

4. What is the better used HiLux year after the DPF problems?

Later N80 vehicles from the late-2020 update onward are attractive options because Toyota substantially revised the 2.8-litre turbo-diesel, increasing output to 150kW and up to 500Nm while making various mechanical changes. Condition, kilometres and service history still matter.

5. Is an old Toyota HiLux more reliable than a new one?

Not automatically. Older HiLux models can be mechanically simpler, but age introduces its own problems, including worn suspension, ageing injectors, seals, cooling-system components and accumulated abuse. Newer vehicles contain more emissions equipment and electronics but benefit from years of engineering development. The best choice is usually the HiLux with the strongest maintenance history, appropriate usage and clean pre-purchase inspection.
