I have a 2017 dmax auto 6 speed the first with the dpf and would like to compare the service costs and faults with other brands up to 110 000 km. The only mod on engine is a secondary filter and have had oil change every 10 000 km which have been performed only by Isuzu dealers.Izuzu services are every 10 000 km or 6 months and the total cost to me has been 5500 . The faults that have occurred along the way are 4x4 low range actuator faulty from new ,20000 km going into limp mode towing up a long steep hill also happened at 80000 km Isuzu still dont know why this happens,100 000 km turbo failure with faulty bearing,101 000 dpf sensor failure causing a tow to Isuzu dealer just now a possible evaporator problem with climate control which I have heard is a issue with this model. Although all of these problems have been fixed under warranty it seems I may have got the vehicle that was built on a Friday or am I expecting to much as I bought Isuzu and was hoping to get at least five years of no hassles and after spending over 25000 on extras should I update or stick with this car and hope as I only have 18000 km of warranty left
cheers

Personally use bt50 and haven't bothered to work out service costs ( it costs what it costs end of story ) only problem since 2016 was a rear main seal discovered leaking during a service and replaced under warranty the next day as we were leaving for townsville the day after . extremely happy with the bt50 But the new model is yet to be proven . As for your dmax going into limp model after a long steep hill , i would suggest its almost certainly the transmission getting hot , do you have an transmission cooler fitted and also a scan guage to monitor transmission temp ?

No I dont have a cooler or scan tool but temp warning light did not come on in the limp mode but has come on when towing manually and has not gone into limp mode but izuzju did a software update to automatically change gears when towing in manual to prevent overheating of transmission
cheers

A Scan gauge, I consider an essential tool, Driving technique can control the transmission temperature, when you can see what is happening. I also tow with a BT50, apart from the rear engine c/s seal initially. haven't had a problem, now at 100,000 K.
No worries , my first thought would still be to fit a scanguage and monitor trans temps , just because the light didnt come on is not a good enough reason to discount trans temp causing the limp mode in that scenario unless there is a log of trans temp in the ecu and isuzu can 100% tell you that the transmission didnt get hot .
Travelyounger Just had a look at your profile and looking at that rig and I would DEFINATELY say it requires a trans cooler and i would 99 % guarantee your limp mode issue is trans overheating related , that's the area you should be investigating .

Hi you just reminded me of a leaking rear seal on gearbox was another issue and your right I should have a trans oil cooler and a catch can I better be nice to Santa

After you fit the transmission temp monitoring device, you will be surprised to see how quickly the temperature can raise when behind a slow truck up steep inclines, or driving in slow stop-start traffic in the city. Speed also has a big effect, and by lowering your speed, the temperature can be kept within the limits. Your rig, its a must.
My car in Europe has one radiator fan, in Australia they added a second fan.
Years ago with our previous car going up Thunderbolts Way, mostly second gear, not towing, the car didn't overheat, but is was extremely hot & I was quite glad to give it a rest for 30 minutes at the lookout.
My car has never gone into limp mode, but with all the sensors on cars these days it is a issue that comes up often on forums. The car is working very hard towing & hills, & it will need some help.

My old man had a DMAX, 1 year earlier than yours, his was back into the dealer at 5,000km with a leaking rear main seal. There was also an assembly error on the gearbox which meant a new housing had to be installed on transfer case i believe.
It was all covered under warranty but took a month.
He had no real issues mechanically after this but the door trim came off on drivers side
I have just bought a current model MUX. Would be the same as your 2016 dmax. Fixed price servicing should be around $3000 for 6 years.
I hope these problems aren't too common.
I only tow 1500 kg.

My limp mode problems with my Pathfinder 08-9 mod., was caused by the following: Mafs sensor - replaced no more problems for 3 months; Suction Control Valve - replaced no more problems for 5 months; EGR - replaced, no more problems for 6months; and finally Turbo Solenoid - replaced no more limp mode problems for 2 years. I had other problems with the bucket of s..t , though so got rid of it recently. It was my first and last foray into ever owning a diesel ever again, except a Perkins powered non electric systems, non turbo Ford D series truck back in the 70's, I think that truck is still running today. I would think if you have 18000km left on a warranty, I would sell, whilst you have a chance at getting a better deal, and buy hopefully something cheaper and reliable. I went back to petrol, but my new car is a slightly smaller motor, AWD, and is very cheap to run and service, but even if you bought a petrol, I would think it would be cheaper to run then a diesel today, due to service and repair costs of a diesel.

I have not owned a DMax but some mates have, and all swear by them and have had a trouble free run with them.
All makes have the odd lemon. It happens no matter what you buy. I have owned a string of Fords since the late 80's and had a really good run with all bar one that was an absolute lemon. Had it been my first Ford I wouldn't have bought another.
So I think unfortunately you may have just got that unfortunate lemon.
Hi John, we have a 2017 model Dmax and have had a few problems. I will list a few here. At the 20K service, an O ring was left off the fuel filter and had to be fixed in Central Queensland by a Diesel mechanic (non-Isuzu dealership). At the 30K service (24K on the clock), they forgot to tell me at the time of pick-up that the vehicle had to have the rear main seal replaced. I should have read the service document but only did so after I had gone home. The vehicle was put in for the rear main seal replacement the following week after I had told them that I was not prepared to drive the vehicle for another 16K with a leaking main seal!!!! They had noted on the service paperwork that the seal would need to be done at the 40K service. When I put the vehicle in the following week, they replaced the main seal and rung me to tell me that they had found a "hairline crack" in the torgue converter and a crack in the bell housing and that both components had to be replaced. This was then done???????????????
When we bought the vehicle new, it had numerous visits back to the dealership with error codes, limp mode etc.
I have a Scan Gauge permanently plugged in to the OBD port so that I can monitor the vehicle myself. Isuzu tell you to leave the vehicle in "Drive" when towing. I can tell you that if I do that with our van in tow, the temperature will climb from approx 82 degrees to over 100 degrees very quickly. The highest I let it get was 110 degrees before slowing down. I locked it in fourth and set cruise control and watched the temp drop back to 82 degrees and that was not in the hot months. When I leave our Dmax in "drive" the temp can climb very quickly to nearly 30 degrees higher which is something that I consider is toooooooooo high!!! I have been told by the dealership that this is normal???? By the way, our van has an ATM of 2.4T and is under that weight when in use. Our towing speed is 90Km/hr.
Isuzu also say that the tow ball weight of 350Kg is ok and that they do not recommend or endorse the use of WDH. In order for us to go along with that proposition, we spent $1K to have an extra rear leaf added to the suspension on the rear so that we could see over the dash board. (The ball weight of our van is 265Kg.)
We previously had a BT50 which had an electronic control module fail on the Gearbox at 59K and Mazda would not grant a Warranty claim. That is why we bought our current vehicle!
So, if you are thinking of asking me which vehicle I would buy to tow our van tomorrow, the answer is "I don't know". I do know that I could fix the temperature problem with an external transmission oil cooler but the vehicle is still under warranty and I do not want to run the risk. Auto transmission specialists tell me that this is a common issue.
We look after our vehicles and do not "bush bash" with them. One mechanic told me that we should drive our current vehicle like we stole it cause they love it. I am starting to think that it is worth a try!

I have a 2016 D-maxine extra cab 5 speed manual, l just can't do autos. So far no problems. I did put a catch can on at 3000km and 600kg constant suspension.
I tow my 2750kg van in fourth gear and no issues with the vehicle to date.

Hi Tones
i
I have had many conversations to the so called experts about oil coolers and oil changes from Isuzu dealers about not needing them done
Every mechanics that I talk to and I know myself as always servicing my own vehicles when not under warranty that auto trans oil should be changed every 50000 and engine diesel every 10000 or less especially towing but those overtrained know it alls at Isuzu must no better yeh right thats when your transmission blows up just out of warranty i would not listen to them and just do it

Looks to be same as my old man had, except his was an earlier year meaning they didnt fix the problem!
What catch can have you guys been fitting to the isuzu. My MUX only has 1000k on it.
I have been looking at the Mann+ Hummel provent. It is just under $400 for a complete kit.
Cheers Pete

Pete I had a chat with 2 guys at Iluka CP, both with D-Max's, both had installed Western Filters Provent and were happy with its performance....so I did the same. Yours may be different for the later MUX.
