Is it the DiD? Early NMs had the 2.8 carried over from the Gen 2 - but I'll give you the benefit of the doubt on this. :lol:
  • Some DiDs appear to have a trouble with coolant solidifying and creating trouble. There is supposed to be a fix for this.
    Some autos struggle with their lockup converter - I don't know if there's a fix for this.
    Gen 3s have a dust sealing problem, which Mitsubishi will fix free of charge - but it takes about 3 days to install.
    Early models were too noisy for the market, which sent a lot of people to the Prado. Later models have extra sound insulation, but I don't know if there's a retrofit option.
Cheers,

Scott

i c not alot of positives in there.

You didn't ask for positives - you asked for problems.
  • Excellent power, torque and fuel economy for a non-common rail engine. Petrol-like to drive, relatively simple mechanically, electronic controlled injection pump allows "chipping."
    Same block as the old 2.8, which is a pretty robust motor.
    The five speed auto with sequential shift is one of the best on the market - except for the lockup issue A FEW have experienced.
    Noise is a subjective thing - suck it and see.
Is that better?

The 4M41 is basically the same motor as the older 4M40 (2.8) except for the 16 valve DOHC head and larger capacity (3.2) plus the EFI set up.
The old 2.8's were good for 500,000K's if looked after properly and I see no reason why a DiD couldn't last as long.
I would suspect that the electronics would start to pack it in along with the fuel pump well before any serious mechanical issues arose.
The motor is still too new to accurately assess longevity but so far there haven't been any major inherent problems like the early 3.0 GU's or 3.0 Jackeroo's.
The issues Scott mentioned are nothing to do with the motor except for the noise issue which was improved on the NP model.

ah thankyou so it would be better to look for a np over a nm?
but the np dosn't have a lsd dose it.

I believe all NM/NP have either LSD or traction control - not both from the factory.

There's no reason (that I'm aware of :oops: ) you can't install LSD into a traction controlled vehicle - other than cost. :cry:
