TOO SOFT!!!
I was so eager to see how well the dmax towed our van I hooked it on with only a few klm on the clock. Less than 1klm a slight dip in the road tripped the stability control . That's what I would call TOO SOFT. Fitted the Outback and more than happy with now 28k on the clock.
Last car was a 150 Prado. Had similar problems once I fitted upgrade suspension. Checked all abs cables for breaks and finely plugged in Techstream and found the steering angle needed re setting. $70 to Mr Toyota problem solved.
Good luck with Isuzu. Toyota are too easy to pass the buck that why I changed Glad I did so far.

Thanks for the feedback, I think I might go get an independent suspension report done and send that and the Isuzu one into head office and try to get something done. I have lost confidence in the vehicle and wouldn't want the ABS to engage suddenly while I am doing 110km down the highway with a 3t boat behind me.

If you had problems with a Prado after the suspension fitment it possibly because the Super Suspension Fitter Drongo only adjusted one side of the tie rod ends and made the stering centre point reference out of whack. After resetting steering angle sensor it was OK. Should be too.
The centre of the rack position would be still out of centre althoughthe senor has been recalibrated.

All this is far too much for a suspension place to handle.

I suspect the same may be happening to HCH too, because as soon as you lift an Isuzu you have to adjust the tie rod ends to corrct the toe out increase, ie, much toe out. If not done equally, side to side the rack is then not oerating in the centre and the sensor will know because you are steering with rack side shifted slightly to maintain a straight line and sensor sees that as incorrect.
These days, suspension and alignment people need to know a bit more than how to just turn a spanner.

Not wrong first time it happened was north of Cairns towing 2.5t of van a slight dip in the road and the car pulled right I thought I had a blow out so stayed off the brakes then it pulled left. After that I disabled the traction and stability when towing until I found out the problem.

Not wrong only used them once. It took them 5 hours just to fit the front. After that I became the Drongo. Got it down to under 2 hours.
Hard to find good help.

Mydmax- I think they had adjusted them as I asked that question and quite rightly they said yes and that had they not adjusted/inserted spacer, then I would have had issues soon after figment, not suddenly now after 3000km. I figure that's a reasonable explanation. Hence going to an independent suspension centre and getting an independent report that it has been fitted correctly, just so I have closed that door on Isuzu. Speaking of which, if by chance you can recommend a north Brisbane suspension specialist that does know what they are doing please let me know. I was thinking of Fulcrum suspension at Brendale, but they don't look like they use OA so wondering if I should take it to an OA place?

They would have to adjust the tie rod ends but. There are no spacers in that mechanism or spacers to be fitted either. Can’t imagine what they mean by spacers.perhaps the dealer man is shooting the breeze with comments which mean very little. They do that with aplomb and surety in their voice to make you think they know what they are doing.

Certainly the steering sensor alignment does require checking to make sure it is correct.
What is the towball weight of that trailer? If going through a dip and the vehicle wallows or pitches nose upward at some point the front wheel/s May momentarily leave the ground and the ESC might detect a correction of one brake is required because of the possible steering sensor issue/check.

The front and rear shocks may not be able to control the mass of the vehicle AND the trailer and increased sudden towball weight/mass in a dip situation. That will send the systems into overdrive of some sort as they are trying to compensate for POOR shock absorber action.
Most modern vehicle have shocks able to do the job, just, but add trailers and weight it is a different story. A suspension specialist advice in your area will be a sound thing to investigate.

I changed all my shocks 2011 model, at 5,000km. The OE ones did not control well, too much bouncing of wheels. If wheels are not controlled to be on the road most of the time the ABS&ESC systems are near useless.
No one seems to do tests on vehicles a short time after they are sold and so cheap shocks create problems. Manufacturers don’t worry about shocks after the sale, they become your responsibility.

Best not to find your shocks are useless by “accident”.

Dmax- the shockies are outback armour and I wasn't towing when the problem occurred. I was simply slowing down for the traffic lights on a dead straight road doing 40kmphr.

I've had outback armour on my 2016 dmax now for approximately 20000 klms. No problems with the suspension or the vehicle systems. Mines the heavy duty expedition. I tow a 2.5 tonne van and have towed it on some pretty crappy tracks and its been fine. My set up was fiited by ABS at slacks creek who are now an opposite lock dealer. Good bunch of blokes, may be worth a phone call to them.
