Thanks. Actually Ive been on a bit of an EV test driving spree this last ten days or so. And have written my small ‘impressions’ on various threads which I felt to be appropriate. As you say, MG ZS came across as a ‘Mature’ product.

Quick update on this:
Thanks to Team-BHP, looks like Tata/Dealer have their eyes on this thread and I got a call 2 weeks back checking to see if I could come over so they can make up for the bad experience - I offerred to visit them anytime they wanted me to and would also share my honest experience here but only if he could check and confirm that their service center had a headlight aiming board/wall that they can use and align my lights, otherwise it would be a waste of time for both of us. He said he will check and get back and its been more than a week and am still waiting on it

Time to put this behind me now and move on - did some diy LED bulb positioning as per Blaupunkt video shared earlier and the throw has gotten better.

Other than this, our NexonEV Max continues to serve us extremely well as a city beater car - daily office commutes, ferrying kids for classes, grocery shopping etc gets done in full guilt free comfort and at dirt cheap running cost

Ending the post with few pictures from weekend diy detailing of the NexonEV Max

I had watched this video of NoiseFaktory that with recent update ev max does not go below 5 percent and Hv critical error would pop up. We need to call the service Center.

I wanted to test this as I do a lot of highway driving.

Took the car to 5 percent near my home and at 5 percent Hv critical error popped up. I could drive till my home and at 4 percent in my parking lot it stopped working. It shifted to neutral and stuck there. I turned it off. Waited for fifteen minutes and turned it on. I could put it back to reverse and park to my parking lot and put it on 3.3 kw charge. It worked without any issues. Zconnect app however is not working since then.

This is true, but is it "HV critical error" or "HV System fault"?

I have started getting HV system fault error recently. This pops up every time SOC go below 7%.

Can you please share your charging pattern from zconnect app? This is seems to be cell calibration issues.

This is not correct. I recently drove my car to 2% battery and there was no such error.

As far as I understand, they have a Nexon EV Prime. So far I have not seen any EV Max with this error. Also has anyone got updates for EV Max? The last I checked with my SA, he said there are no updates to be done and it is the latest version.

I didn't resubscribe for zconnect after its expiry. 90% of my charging is through 7.2 KW AC fast charging.

It is more about charging pattern. Are you charging to 100% every time and are you discharging to below 20% once a month?

You are right. This is HV system fault. I got this at 5 percent and the car was unmovable at 4 percent.

I have driven my car to 2 percent many times. There was no error. This time after service this issue happened. I have driven more than 48000 kms in about one year and one month.

Noise Factory initially had prime then they got EV max I think... this issue was for max.

My drives are mostly on highways, so the car very often goes through the full charge cycle. After 3 DC charge cycle, it generally goes through AC charging 7.2 or 3.3 to 100 percent at hotel overnight. I also have extension cord with earthing, and I prefer to charge it using 15A. So the battery is well maintained. I also regularly take it to below 10 percent and charge all the way back to 100 percent using 3.3 KW charger.

If feasible and no one waiting, for DC also I charge 100 percent while I am, waiting at mall or restaurant.

This is a new issue post update I think. Range update I actually got long back. Max is super aggressive if the SoC is below 10 percent, the limp mode is on and you will easily get 4-5 kms in 1 percent drop if you use city mode and region 0 properly.

Sports mode with region 0 gives a good range. During my recent drive to Mysore, 2 hours 30 mins door to door, I was driving at 100-110 in Sports mode and I covered about 170 kms in 54 percent battery.

Discharging below 20%/month - Yes , but not that consistent on making it to 100% every time.

Is there any update from SC on this?

I also got my car serviced a few months back there was no software update done. I have driven my car for 19600 kms in about 10 months and i have not faced any such issues. Nobody in our EV group has even mentioned about any such update.

Making it to hundred percent every time is crucial for BMS to understand the full capacity. Opportunity charging should be avoided as much as possible.

OK. Got it.
Is the damage reversible now? Would a re-calibration or BMS update fix this?

Yes it is reversible. It is try to charge to 100% on slow charge and discharge to 10% and charge to 100% percent again. Follow this 2-3 cycles and then try to go below 10%. If this doesn't work, then you will have to take the car to service center.

Please note: Charging to 100% means that the car should not be driven in between the charging cycle.

Thanks. Will give it a try!

Anyone facing suspension sounds?

My Nexon EV Max makes clicking sounds on acceleration and deceleration and over bad roads. I have been complaining to the service centre on every service. They do some adjustments and it reappear after a few hundred kms. Even my co-brother faces the same issues. The service advisor said the issue persists with all Max cars and it has no resolution.

Has anyone faced similar issue, please do reply. I am thinking of writing to the company about the issue.
