Guys an important task for all Isuzu Vcross owners to do, as most are aware clutch failures have embarrassed Isuzu enough - luckily for me at 35k i have had no failures or even symptoms!
Isuzu has already issued a recall since some time and has been emailing customers in a batch mode.

I went ahead and got mine done (though i didn't get any email) but since i was planning a trip didn't want to drive in the fear of the clutch pedal going dead in a remote place.

Isuzu have been replacing master cylinder left right and center for many customers but most cases the problem appear to reappear - this was frustrating for most customers and embarrassing for both Isuzu Japan and India.
The core of the issue actually has been the rubber pipe that goes to the master cylinder eventually(heating up and) ended up producing small rubber particles that contaminated the master cylinder and had it fail. So essentially it isnt exactly the master cylinder which was originally thought to be the culprit.

The solution to this problem is to fit a new improved pipe(hopefully) and a new master cylinder and do a full oil replacement and bleeding. Pics as below :-
This time also experienced the new Bavaria dealer in Pune and was very pleasantly surprised with both their customer engagement and their technical expertise(apart from the facilities).
This was done as part of warranty and i wasn't charged anything, the whole process was done in an hr or so.

It is never easy to diagnose consequential damage and Isuzu did a good job at it. Good that a recall has been issued.

It is a really helpful detailed build, Iron Rock.
Many thanks for sharing your experience.

Some experiments dont exactly go to plan! The upper arms experiment is a failure!
I had put in custom upper arms from overland plateau an year back or so - while it took care of reducing the stress on steering - it didn't really help as i underestimated the physics side of it.
The upper ball joint was too close to the tires and i didn't have any negative offset alloys or didn't want to put in spacers.

I have gone back to the original arms - will need to keep an eye if it puts any unnecessary stress on the steering. It was never bad, but sometimes we tend to overdo it in enthusiasm! We fail, we learn!

Have you considered installing ball joint spacers instead?

Hi Faisal nice to have you on the forum, yes i did consider, but generally avoiding spacers, to be honest my lift wasn't big enough to warrant an upper arm upgrade - i am back to normal upper arms and those are working fine.
On your email, apologies i dont have the circuit diagram, it was more a trial and error method as i didn't have it - also i didn't do any ecm changes, its a piggyback cruise control which only picks the vehicle speed from the ECU speed sensor line, rest of the it is direct control through pedal signals.
