The 2400rpm hesitation was fixed using:

TNS63/11 Hesitation on downshift under acceleration.

It was issued on 26/08/11

This is the thread http://www.pradopoint.com/showthread...round-2400-RPM a word of warning on this fix it WILL make your truck use more fuel around town, typically up to 14 - 15ltr/100km (worse case)

The surging problem is fixed under TNF52/12

So my 2013 should already have all this do you think?

I believe that there was an update in March 2012 & 1 after that. See my previous posts. The march 12 update altered the gear changes and fixed the drone. I'm getting 10.3 litres/100km around Adelaide, City driving only. Not sure if your build has the latest updates. See my previous posts for more info.

Mine is a late 2012 build , its was a bit harsh at first but it is gradually getting better

Mine is pretty smooth these days, for a diesel, probably combination of my vibration fixes, ecu updates and age. I certainly don't notice it anymore.

Interesting that the new model appears to be running a different ECU setup

I have the new facelift model Prado (GXL, Auto, diesel, Jan 2014 compliance) and experienced the 1500 RPM drone up until the 1,000km mark. After the 1,000km its completely gone and doesn't exhibit the drone any more!

I have a face lift GXL plated dec 2013 bought new feb 2014. Had a noticeable drone at 1500rpm, not horrible but annoying. Fitted safari snorkel yesterday, amazing difference! Quiet as a mouse now.

Thats good to know. I've been toying with fitting a snorkel for a while now but didn't want to introduce anything that might give the dealer cause to wipe their hands of it. Given they have been absolutely useless so far (north point at hilcrest) I think I have no choice but to get one fitted. Disappointing really on Toyota's part.

I have a Feb 14 build GXL Manual, and for the first 1000km, I drove it on the freeway from Bris to Sydney, didn't really notice any drone. Since doing another 500km around Sydney in slow traffic, frequent gear changes etc I think I have the dreaded drone at 1500RPM.

At first I thought I was just driving it in too low a gear when at 1500rpm (despite the engine feeling willing and not struggling), so have been dropping back a gear and increasing rpm to above 1700-1800 it goes away. Problem is that in traffic, 2nd gear and 1500rpm is exactly where you need to so often be driving it, and it's driving me nuts.

I will be booking into the dealer ASAP, because it has really made my owning a brand new car a disappointment.

Yep. Car much quieter since fitting an Airtec. Car is a 2014 TD auto.

Just had a Safari snorkel fitted to my April '14 GXL yesterday. Big rattle when idling and the AC cuts in. Even feel it back up through the brake pedal. BUGGER!!!!
