Completely agree with you, just finished reading through this thread and amid all the technical stuff and considerations for the manufacturer the bottom-line is that
when a driver presses the brake pedal the vehicle should stop and we cannot have brakes not working in 2020 regardless of the manufacturer. Like chiefpk rightly said this is not done Kia.

We must raise our voice against such issues to a bigger level until there is a proper solution, and we here at Team-BHP are very well capable of doing that. |
Sad but true, no response from the manufacturer is troubling. If the issue was acknowledged, thoroughly investigated and updated to the customer at least, imagine the brand loyalty it would have created(we are very good at that, look at Maruti and even Hyundai). I am guessing that this has been hushed up to keep the sales flowing but the damage it has done done to the brand's image is deep. Might not be a lot in numbers but these things do add up in the long run.
Just to compare VW had to shell out close to 12billion USD in fines and damages along with stock prices crashing and most importantly erosion of trust with the customer. All this for essentially lying about emissions, imagine this issue happening in the US.
While the issue still remains unsolved just some concrete and positive communication from Kia would've done wonders to at least their paying customers if not potential ones. Hope it gets solved soon.

They should create a complete syllabus (classroom + CBT + theory exam + full motion simulator) covering all their unique scenarios so that owners can learn how to drive their vehicles safely. Only Hyundai/Kia type rated individuals should be allowed to sit behind the wheel & operate the vehicles. |
Thanks ChoosetoCruze in an otherwise dark thread that was witty and hilarious. Imagine the number of "non-normal checklists" they'll have and the size of their QRH

Would love to see their "test drivers" respond to such situations in real world times, can't help but get reminded of the investigation about response times in the movie Sully.

I can think of some scenario where this could happen due to some very rare failures of other components perhaps? It will be interesting to see if the manufacturer/dealer comes with any sort of response. |
I am not that well versed with mechanicals and might be wrong here but came across some info which
could be related and explain this issue. I stumbled upon some links(If it was in this thread, I apologize for not quoting the member, please let me know) which led me to this
https://www.motorsafety.org/hyundai-...oster-issue-2/.
Its not the same vehicle or the same car manufacturer(technically) but the similarities to this issue can't be ignored.
It involves a manufacturing defect in Mando America's brake booster fitted in Hyundai Elantras (33803 in number), manufactured in the years 2016-17 and the defect is stated as :
"
Brake boosters in these affected vehicles are possibly subject to a manufacturing error, leaving them prone to failure. The Part 573 Safety Recall Report said that the boosters could lose power after the diaphragm within them comes loose."
An excerpt from the related NHTSA report : "
An investigation was initiated and four claims were identified with customer statements of high brake pedal effort."
Do read the report for details, the notes are eerily similar to the ones being discussed here :
https://static.nhtsa.gov/odi/rcl/201...7V063-8851.PDF
Also worth noting is that
four claims led to this issue being identified and issue a recall of 33803 vehicles. I really look forward to the day when we have such customer protections in India.

Completely agree, I was surprised by the force it took to stop a Wagon R 2017(non ABS) from rolling back in the garage with the engine switched off(was stupid enough to test brake lights without the parking brake). Just for the purpose of learning here is a video of a power steering failure during a moose test. For now, let's keep aside the fact that the car happens to be a Hyundai i30, the video is in Swedish but the footage, reactions and expressions are important :
The points to be noted are :
1. How the car behaves when the power steering fails (the initial clip where it just continues straight instead of turning)
2. The surprise or rather shock experienced by the driver when it happens(in cabin footage along with the part where the driver is explaining the incident).
3. The effort required by the driver to turn the steering wheel at 0:29 in the video.
This happened to a seasoned team when they were doing the moose test, on purpose and are accustomed to a vehicle not performing as expected. Even then this came as a shock as a power steering failure isn't a normal/expected issue and the force required after that was overwhelming(in that short time span) to make the turn.
Imagining a similar situation in real world with an average driver, related to critical systems(brakes/steering/engine). It sends chills down the spine and this has actually happened to some of us is frightening.
Kia(any manufacturer) should pull up its socks and not just fix it but also communicate actively about it.
Its not just about staying safe but also feeling safe.
