Mitsubishi Triton Problems: Used Buyer's Guide for MQ, MR and MV Utes

The Mitsubishi Triton is the value ute, and a decent one. Its 2.4 MIVEC diesel is reported to suffer EGR and inlet carbon build-up on city-driven utes, which can mean limp mode. Manuals can jump out of third, rear springs sag under constant loads, and a towbar wiring harness recall covers more than 100,000 MQ and MR utes. Check the history and recalls, then get it inspected.

Which Mitsubishi Triton generation are you looking at?

MQ (mid-2015 to 2018). The MQ arrived in mid-2015 in two or four-wheel drive and three trim levels, all with the 2.4-litre MIVEC turbo-diesel (133kW/430Nm) and a six-speed manual or five-speed auto. It scored five ANCAP stars, with a 16/16 side-impact result (carsales, buying used MQ 2015–2018). carsales also notes litigation over the MQ's advertised fuel consumption figures.

MR (2019–2023). A facelift with the same 2.4 engine (133kW at 3,500rpm, 430Nm at 2,500rpm) and a six-speed manual or six-speed auto. WhichCar notes the five-star rating dates from 2015 and that utes built from January 2023 are classified unrated. The MR carries Mitsubishi's 10-year/200,000km warranty and 10-year capped-price servicing, with 12-month/15,000km intervals and the first service priced at $399 (WhichCar, 2023 Triton MR review). Mitsubishi's long warranty has conditions, so check what applies to the ute you're buying.

MV (2024 on). The current Triton uses a 2.4-litre twin-turbo diesel making 150kW/470Nm (CarsGuide, Triton overview).

What are the most common Mitsubishi Triton problems?

These are reported by Australian motoring experts and owners. They're not failure rates.

EGR and inlet carbon, limp mode

carsales says diesels that blow black smoke or won't rev should be avoided: carbon sticks to the manifold and blocks the EGR valve, hurting performance and costing "sizeable amounts" to fix. It warns that EGR bypass kits breach emissions rules and can damage the engine (carsales). Drive reports Tritons suddenly losing power into limp mode, traced to soot and carbon in the inlet manifold and turbo boost pipe, most common on utes used only around town. It also says owners complain of surging or hunting on light throttle, with software and sensor updates not always fixing it (Drive, Triton used car review).

Manuals jumping out of gear

carsales says manual Tritons can jump out of gear, usually third. Its test: tap the lever gently while accelerating. Mitsubishi service departments offered a retro-fit that also protected against accidentally selecting reverse (carsales). CarsGuide's Q&A adds that a reverse gear that only baulks with the engine running is a classic dying clutch (CarsGuide, Triton problems).

Diesel clatter and valve clearances

carsales says excessive clatter at start-up or under load can mean the valve clearances urgently need adjusting (carsales). This is an engine that needs its maintenance.

Sagging rear springs and tray rust

Rear springs under constant heavy loads sag, giving a rough unladen ride and risking bottoming out. carsales suggests looking for around 100mm between tyre and wheel arch on 4WDs and checking the ute sits square. It also says to lift the bed liner and check the tray floor for dents promoting rust (carsales).

Hard-worked and modified utes

Drive's advice is to be wary of a lifted ute with mud tyres and a winch, or a monster tow hitch, as signs of a hard life, and to check the underbody for scrapes and dents. It also notes lift kits can create insurance and registration hassles (Drive). CarsGuide's Morley says he'd take a 150,000km ute with full history over a 60,000km one with none (CarsGuide).

What Mitsubishi Triton recalls should I check?

We confirmed these on the federal register at vehiclerecalls.gov.au. Check by VIN with a Mitsubishi dealer or Mitsubishi Customer Care. Older MN Tritons may also be in the Takata airbag recall; see our Takata guide.

What this means for you: on any MQ or MR with a towbar, confirm the harness recall is done. On a coastal ute, check the side steps. Mitsubishi fixes recalls free.

What our inspectors check on a Mitsubishi Triton

This is what we look at, and which package includes it. It's a list of checks, not a claim that the ute has these faults. Ute, Van & Light Truck includes everything listed for Comprehensive.

1. 1.OBD-II scan of stored, pending and live codes, including boost, EGR and airflow codes that point to carbon build-up, and a look for recently cleared codes. (All packages)
2. 2.Engine bay and leak check, plus battery, starter and alternator tests. We note diesel clatter and smoke colour. (All packages)
3. 3.Brake pads and tyre tread measured. (All packages)
4. 4.Full mechanical inspection. Engine, cooling, intercooler hoses and pipes, gearbox, mounts, exhaust, driveline and steering. (Comprehensive, Ute, Van & Light Truck and Elite)
5. 5.Transmission checks. Gear retention under load on manuals, clutch engagement, auto shift quality, 4WD engagement. (Comprehensive, Ute, Van & Light Truck and Elite)
6. 6.Suspension bushes and mounts, leaf spring sag, ride height and whether the ute sits square. (Comprehensive, Ute, Van & Light Truck and Elite)
7. 7.Undertray removed where fitted, safe and permitted, with underbody photos. (Comprehensive, Ute, Van & Light Truck and Elite)
8. 8.Full electrical test and interior electronics, including the towbar wiring where fitted. (Comprehensive, Ute, Van & Light Truck and Elite)
9. 9.Exterior paint and body repair indicators, tray floor under the liner, side steps, plus an odometer rollback check. (Comprehensive, Ute, Van & Light Truck and Elite.) Elite adds a paint thickness gauge on every panel.
10. 10.PPSR check. (Comprehensive, Ute, Van & Light Truck and Elite. Essential doesn't include one)
11. 11.Cold-start assessment by a senior inspector, when the seller leaves the engine cold. (Elite only)
12. 12.History deep-dive (odometer, owners, stolen or written-off status and recalls) and a valuation. (Elite only)

Road tests are 3–5km on Essential, 6–10km on Comprehensive and Ute, Van & Light Truck, and 10–12km on Elite.

How should you test-drive a used Triton?

• Ask for the engine cold. Listen for excessive clatter and watch for black smoke.
• Accelerate hard once on an on-ramp. It should rev cleanly with no black smoke or sudden power loss.
• Hold a light, steady throttle at 60–80km/h and feel for surging or hunting.
• On a manual, accelerate in third and tap the lever gently. It must stay in gear. Try reverse with the engine off, then running.
• Drive unladen over a rough patch. A harsh, crashy ride can mean sagged springs.
• Try 4WD and low range in a safe spot.
• After the drive, check under the ute for drips and look at the tray floor.

What paperwork and PPSR checks do you need?

• A PPSR check. Work utes are often financed. It's in Comprehensive, Ute, Van & Light Truck and Elite. See PPSR check NSW.
• The service book at 15,000km intervals, with invoices. Any EGR or inlet cleaning should be recorded.
• Recall completion by VIN, using the table above, especially the towbar harness.
• Warranty status. Mitsubishi's long warranty has servicing conditions. Ask the dealer what remains on this VIN.
• Usage history. Trade, farm, council or mine use. Drive's advice: buy a standard, unthrashed ute and add accessories yourself.
• Modifications. Lift kits, winches and big hitches. Check they're legal and insurable.

How do you negotiate on a used Triton?

• Black smoke, limp-mode codes or a hunting throttle are real costs. Get the EGR and inlet cleaning quoted.
• A manual that jumps out of third is a gearbox job. Big discount or walk.
• Sagged springs mean new springs. Price them in.
• Torn trim and cracked plastics won't affect the drive, but carsales says they justify shaving the price.
• Open recalls must be done before you pay.

Our Elite inspector can negotiate on the spot, using the findings.

Is a used Mitsubishi Triton a good buy? Our verdict

Yes, for the money, if it's been serviced and driven on the open road sometimes.

• MQ auto: the five-speed is smooth and quiet. Check the EGR and the towbar harness recall.
• MQ manual: cheaper, but test third gear and the clutch carefully.
• MR: six-speed auto, longer warranty if the conditions were met. Confirm what's left on the VIN.
• MV: more power, newer tech. Still check it like any diesel ute.

Mitsubishi Triton FAQs

What are the most common Mitsubishi Triton problems?

Australian experts report EGR and inlet carbon build-up causing poor performance and limp mode on city-driven utes, throttle surging, manuals jumping out of third gear, sagging rear springs under constant loads, and excessive diesel clatter from valve clearances. A towbar harness fire recall covers 2015–2019 utes. These are reported issues, not failure rates.

Why does my Triton go into limp mode?

Drive says it's usually soot and carbon in the inlet manifold or turbo boost pipe, most common on utes used only around town, and that a good highway run can burn it off. The EGR valve also clogs with soot and oil. Scan the ute for codes, check for black smoke, and ask for records of any EGR or inlet cleaning.

Is the Mitsubishi Triton reliable?

Generally, with maintenance. CarsGuide's expert says modern turbo-diesels are highly strung and need injectors, filters and pumps as they age, and that he'd rather a 150,000km ute with full history than a 60,000km one without. The Triton's main issues are carbon-related and preventable with highway running and regular servicing.

What is the Triton towbar recall?

REC-005048 covers 102,616 MQ and MR Tritons from 2015–2019 fitted with the genuine accessory towbar wiring harness. Incorrect installation can let liquid into the circuits, with a risk of overheating or fire. Only utes with the accessory harness are affected. Mitsubishi reinstalls the harness free. Check the VIN with a dealer.

Does the Mitsubishi 10-year warranty transfer to a used Triton?

WhichCar lists the MR Triton with a 10-year/200,000km warranty and 10-year capped-price servicing. Mitsubishi's long warranty has conditions, typically around servicing, so ask a dealer what remains on the specific VIN before you rely on it. A full dealer service history is what keeps it alive.

How much can a Mitsubishi Triton tow?

Towing capacity varies by generation, body and drivetrain, so check the compliance plate and the owner's handbook for the exact ute. Drive warns that a monster tow hitch suggests the ute has hauled serious loads and may have worn faster, and carsales notes a caravan drains the tank much faster than the advertised figures suggest.

Which Triton gearbox is better, manual or auto?

carsales says the MQ's five-speed auto works fine off-road and is smooth and quiet for commuting, and recommends it unless you're a die-hard. Manuals can jump out of third, so test them carefully. The MR moved to a six-speed auto, which WhichCar says rarely hunts for gears.
