Re: Automatic issues

No sorry was referring to the hesitation you get when exiting a corner and you accelerate before the car has straigtened up. Its like traction control being over cautious but it does not appear to be the TC causing the hesitation

I still have this problem and it is really starting to piss me off now, it is a real niggle more than anything as it only does it infrequently. It is only noticeable when exiting roundabouts as you accelerate out and start putting your foot down. I mentioned it at the first 1,000km checkup, they reset the computer and the problem still occurred. I asked again at the 10,000km service and was told that the 'techs' did notice it when taking the car for a drive, they then returned to the workshop removed the floor mat (Sangrabber) and the problem went away.

I couldn't believe this was what they were saying was the cause when I picked it up from it's service and they even had a notice dangling from the rear view mirror stating they had removed the incorrectly secured mat due to safety concerns! needless to stay I discussed at length with the service department as to how they thought this was possible and that if it was the floor mat it would do it all the time not just on roundabouts. They asked me to see how I went with it and come back and take one of the techs out for a drive myself if the problem still occurs. Well one week post service, with no Sandgrabber mat and only the toyota genuine mat and surprise, surprise the problem is still occurring. I will be taking it back when I get chance to take that 'tech' out for a drive..... :evil:

Re: Automatic issues

Wow, they thought a mat was causing the hesitation in acceleration? Interesting technical solution.......lol

Hi Mate

The 150 has AI Artificial Inteligence. Not its best feature.
Drive in "S" you will overcome the problem. Down change at the drivers discression, the way it shoiuld be!!!!!.

Agreed, it's a work around for sure but why as owners of $60k+ vehicle should we have to? Toyota need to fix this obvious software glich as well as the other "known" problems. I am really tired of hearing the service guys say they have never seen or heard of these problems before.

Guys, see my post under the 2400RPM flat spot thread.

They reprogrammed the ECU at my last service and the problem is gone. It no longer overheats and the hesitation when rounding courners has gone (it use dt happen every time I made a left turn from Webster Road into Gympie ROad - outbound) but it does not do this any more.

At the next service ask them to reprogram the transmission ECU.

Nity...

Re: Automatic issues

There are odd issues with the auto trans. The down change appears to be activated by the brake light circuit. If you touch the brake pedal the transmission will down shift.

Yes it is normal to have the transmission hold the lower gear for a while. Normal but not logical.

Little about the Prado 150 is logical. For example the manual up and down shift is the wrong way round.

To get around this use S mode and select fifth. However, you then need to go back to D when needed.

The S mode is not a sportier mode it is a manual mode where the transmission computer will override your selection if you exceed certain parameters. For example if you leave it in fifth and stop the car the transmission will select first gear.

The other problem is gear selection when accelerating from an intersection. The transmission’s initial reaction when the accelerator pedal is pressed is to change up and so the car goes no where. Then the transmission will down shift and you will then accelerate.
