Hence IMO, it is ABS malfunction. Engine vacuum has no roll in this catastrophic brake failure.
For an experiment sake, BHPian interc00led and I took my Creta to a road with 'NO traffic' and then removed the ABS-related fuse (40A) from the fuse box in the engine compartment. Drove the car at various speeds like 10kmph, 30 kmph, 50kmph and tested the braking performance at each of these speeds. The car did manage to stop but experienced wheel locking on gravel road since ABS was not functioning but on smooth tarmac, it was stopping normally with no pedal feel. Also no hard pedal feel issue was experienced during the tests at all.

I still have a hunch that is it the Brake booster that is to be blamed here. Mando is the manufacturer of the part of the ABS unit.

With the fuse removed all you have done is disabled the ABS. The brake booster is still working normal. So the car would feel completely normal and brake completely normal. Only the ABS would not kick in when braking hard.

Put the fuse back and disconnect the vacuum line to the booster. Try again. I suspect the brake will feel very hard, but if pressed hard enough, everything will still work, including ABS.

Shall try this too and see how the braking is and 'pedal feel' too without vacuum.

I had disabled the ABS since I wanted to be sure that it was not the ABS system that was causing the 'hard pedal feel'.

Slightly off topic, Tigor that I had bought 2 years ago still had plenty of niggles and horrendous A.S.S experience. You can even check Harrier thread with issues reported even by version 2.0 owners. Yes Hyundai/Kia needs to take this issues seriously, but this doesn't mean our Desi companies are innocent.

Yes, issues will be there in any car. And every manufacturer/dealer/service will have their shortcomings. But could these issues and shortcomings give you a heart-attack or in worst case kill you, despite you taking good care of it and driving sanely.

I had pretty much decided Seltos to be my next car, to get in the next year or 2. But now, I have to sadly look at something else till there is a concrete solution to this issue.

Although it is obvious for one to wonder if the driver actually did not press hard "enough" and it was just the hardening of brake rather than a complete brake-failure, but IMHO during such conditions where the driver wants to brake in order to avoid hitting another vehicle in the front(or even a bad-patch of road), the instinct of the driver WILL be to press harder as his vehicle comes closer to the object(that he is trying to avoid hitting), and so it will be human instinct to press the brakes as hard as possible. In so many situations I have had to brake very hard to avoid hitting 2-wheelers(parked 2W trying come on to the main road) or even pedestrians/kids(playing on a street that sneak up on you when you least expect) and ended up braking so hard that my car almost skidded for a meter or so. So I find it very hard(pun intended ) to believe that a driver would not brake hard enough under such emergency situations just because he/she is not used to such level of sensitivity of brakes.

As a Seltos owner it now makes sense what seems to be the issue. It's definently a manufacturing fault in the first lot. When my vehicle had drowned during the Amphan cyclone. The car was in the workshop for over a month and while I was supposed to recieve the car in a coming few days- I got a call came from the service station stating that the break vaccum has been spoilt after several test run observations and requires a replacement to which we said yes.
Definently the mechanics must have encountered the same issue while testing my car after fixing it and noticed the failure. Hense forth they replaced that part from my car to avoid any major chaos. No wonder my vehicle took around 2 months to return back home.

Don't we also do the same while reviewing a TATA car ? A standard statement in CONS

" - After sales service a hit or miss "

Where as this happens with almost every manufacturer now a days.

I had lend my a new Kia Seltos from my family friend for the last two days and braking was the first thing I noticed to be bad. I did have a couple of heart in the mouth moments where I pushed my pedal to metal but the car wasn't stopping at all. I did inform the owner about this and asked him to get it fixed asap.

ABS can increase distance in some cases like gravel and ice but in these conditions it provides greater control of the steering keeping the car on line. However, when ABS is used on surfaces like normal macadam roads or concrete roads ABS will reduce distance as the wheels will not lock or skidding. Skidding increases distance of stopping on such roads besides one losing control of the car.

I don't know if something similar has been posted before but this is what a user in the Seltos Owner's group on facebook posted.

Brake failure issues in the Kia Seltos-screenshot-20201020-14.07.03.png

Hope this helps resolve the issue and concerns raised on the thread to some extent.
