Thanks a lot, rohit.pahuja19, for sharing this vital information. Very useful for current and potential XeV 9e owners. But as many members here have suggested, if M&M were aware of this issue, they should have proactively done a recall and replaced the LV battery/ updated the software. Initial lot of XeV owners are the Beta testers for the company and utmost care should be taken to address immediately any issues reported by them.

I want to share my personal experience here related to the topic of recalls. 10 years ago, when I purchased my TUV3OO, within one month of the car launch, I knew I was going to be one of the Beta testers. But I took the risk knowing that M&M has a very responsive after sales service & God forbid if I encounter any issues, those will be addressed immediately.

When I went for the first scheduled service of my car (3K km), the Service Advisor checked in their DMS system and informed me that my car is from the batch wherein two parts have to be replaced (recall).

• Vacuum Modulator and
• Fuel Delivery Module (FDM)

When I met the Service Head at the MASS, the first question I threw at him was why Mahindra is not doing a voluntary recall to replace these faulty parts and waiting for customers to come there for their first scheduled service to get these replaced, I got some interesting piece of info from him. He said that there are three types of recall:

• Red recall
• Blue recall and
• Green recall.

Red Recall is for serious issues/parts which would jeopardize the safety of occupants. The example he gave was that of the XUV's power steering hose failure. This would result in leakage of PS fluid, jamming the steering and ultimately loss of control. Hence there was a mandatory recall for XUV's PS hose replacement.

Green Recall is for those items, which don't jeopardize safety but result in below par performance of the car. These parts are replaced during the regular scheduled services; there is no need for a separate recall. The above mentioned 2 TUV parts being replaced are a part of such green recall.

Blue Recall is for parts, which don't jeopardize safety or performance, but have to be replaced nevertheless as they are faulty. However, these are replaced only upon failure.

Not sure if this recall system is still being followed at M&M, but if it still is, then the LV battery failure would come under the Blue recall as it is neither jeopardizing the safety nor affecting the car's performance. However, the electric twins being a marquee product for M&M, they should not wait for customers to report the LV battery failure and pro-actively replace it & correct the software. This can go a long way in instilling the confidence in the product and after sales service. At the end of the day satisfied customers are the best marketing tool and their "word of mouth" publicity can ensure ever increasing demand for this car.

Thanks for sharing this knowledge and experience. I want to throw my perspective. A car is not a product like LED TV in your home. You trust your car, and take it to places. In fact, on many occasions, YOUR CAR IS YOUR SAFETY.

Imagine a scenario, where a young lady took this car out to an unfamiliar place and got locked out of the car with mobile inside it. (Due to LV battery issue).

So, I do not agree with all this funda. Totally irresponsible on the part of MM, to not replace these by doing a mandatory recall!!

Completely agree with you. LV Battery controls the start/stop and many functions and is a important for safety. They should do a voluntary recall of effected vehicles.
Mahindra has global ambition and also the ability to sell these cars globally. They should catch up with global best practices of voluntary recall by manufacturers.

They are regular lead acid batteries. Yes OEMs could opt for AGM or preferably LFP for enhanced reliability. I hope they do at the earliest.

I called the service center immediately and told them about the same. They informed it could be a battery issue and would require the car to be inspected at the service station.
Luckily i was at home, and after waiting for 2 hours they arrived at my place to inspect the car. They got the battery along with them. When they inspected the battery was completely drained it showed giving 0V output. They replaced the battery and asked me to drop the car to the service station.
Today they informed me that this happended due to issue with exide battery and also the software installed is outdated. They would replace the battery with new Amaron battery and have updated the software.
They even told that it's been an issue with many xev owners. Now they will keep the car for another day and check with the new battery and if everything works fine, only then they will handover the car to me.
Now am little concerned that if this issue is known to Mahindra then why all the cars aren't being called back for software update battery repacement.
My only motive to post here is to inform everyone to check with their respective service stations about the softwate update or battery and get it sorted.

So exactly the same thing has happened with my XEV. I took delivery on 25th March - odometer is only at 650km. I charged it a few days ago and drove it last night - battery was at 70% roughly. Tonight i go to the car and its not responding at all - not unlocking with the key or physically and also the app is not working. I am assuming it is the same battery drain issue with my car - i am running one of the early release versions of the software - it has not been updated yet and i have noticed my regular battery draining also 1-2% a day while parked in idle position. Hopefully a software update and change in lead acid battery will fix it but still very disappointing that this happened. Thankfully it was parked at home - if it happened while i was travelling it would have been infuriating after paying 33 lacks for a car. So please everyone who took early deliveries - get your lead acid batteries checked and software updated. This issue seems to happen after a month or so of delivery.
How did the service center people get into the car to open the bonnet to replace battery? Since the car is not responding to the key at all? Is there a way i can manually open the bonnet to jump start the battery?

Open the driver's door using the manual key (slice open the key fob to find it). Once inside the car, open the frunk.

After this, you would have to unscrew the whole frunk (it's a lot of screws, either call service centre folks or RSA). Once the frunk is opened, they would perform the jumpstart and voila, the car comes back to life.

I feel if a car was genuinely worth booking multiple times, maybe it was also worth waiting a little longer—especially when it was never going to be an indefinite wait. A little push here and there on social media and you would be sorted.

What’s puzzling is going from an XEV - tech-forward, future-proof EV to an Isuzu that’s well, dependable but hardly innovative and almost obsolete in most areas compared to new age vehicles. When you look even at the design of both vehicles - the later looks an eyesore (compared to XEV atleast) and that feels less like a practical pivot and more like a pride-fueled detour. Almost like saying, “If I’m not getting exactly what I want now, I’m walking”—and then settling for something just to prove a point.To me, it looks less like a win and more like a consolation trophy for impatience.

I frankly totally dis Reasons..

1) Multiple bookings: Booked one in White and one in Red, as that is the only way to book for colour options if you are not sure at that point in time. Frankly eventually liked Green the most, though was OK with Red. Cancelled White within a week as soon as I was clearer on the colour.

2) Thar ROXX was a booking from October launch day while XEV were booked much later and could have taken 1 of each if I hadn't been so disappointed with Mahindra.The issue wasn't wait times but others whom I knew in my locality getting vehicles out of turn. Infact for the ROXX the dealer too did an additional booking on my behalf which was at a later time point that mine so I initiated a refund immediately and cancelled that.

3) I was offered an out of turn Green XEV 9e by the dealer with whom I had cancelled the white with the condition that I do insurance with them. Both counts didn't go with my conscience so declined. (Have recorded whatsapp chat with the SA). I also escalated this malpractice to Mahindra which did nothing about it.

Isuzu replaces my Thar RoXX booking.

The BMW X6 was to be replaced by XEV 9e but I do 24 hrs drives of 1600kms one was two three times a year. Most of the drive is during night hours. But XEV is counterintuitive as in one needs to drive slow to tap into the 500km range else it is 350-400 kms in high speed 100kmph drives. Meaning one goes into a minimum of 1 hr charge cycle in the middle of nowhere every 300 km at the most. One needs to compromise on where one has our food and bio breaks rather than outlets of one's choice.

As you would notice, fuel costs were the least of my concerns here. Some safety features like drowsiness detection, Lane departure warnings on the XEV did attract, but the buggy software reports kept a balance of the pros and cons.

Everyone has a different point of view and different approach. Yes the Dealer didn't handle my booking properly and that is logically enough reason to cancel the booking and look elsewhere, why would one compromise on one's dignity just because a car is overbooked.

By the way got the XEV refund for both bookings fast AFTER escalation. 1 ROXX booking refund is still pending. Two refunds till date took more than a Month and 1 happened in a week.

Thanks for sharing your experience! I learned a lot from your post.

It’s disappointing to hear how your booking was handled, especially when you followed all the steps properly. I agree that no one should have to deal with out-of-turn deliveries or be forced to buy insurance just to get a car. You made the right decision by standing up for what’s right.

I also understand now how difficult long-distance EV trips can be. On paper, the XEV 9e looks great, but stopping for an hour to charge every 300 km — especially during night drives — sounds tough. Your post helped me see the practical side of EV travel better. Though it really depends on how you drive, since you cruise at speeds like 100 km/h, it’s hard to get the full 500 km range, especially on hilly roads.

If anyone else is waiting for XEV 9e delivery, here are a few tips I’ve picked up:

1.Stay in touch with the dealer — call every 3–4 days for updates.
2.Ask if any test drive vehicles is coming soon. Sometimes your booking can
be aligned with that for quicker delivery.
3.Check which colour options are available sooner — usually, white or black
shades get allocated faster.

Wishing you all the best with your new Isuzu! And thank you again — your post really helped me understand more about both the car and the booking experience. I’m also planning to buy an XEV 9e, but I’m waiting for Pack 2 (79 kWh). Even though I only do about 3–4 long trips per year (around 590 km one-way), we usually stop for lunch. There are two Junior Kuppanna restaurants along the way. While going, we use one depending on the time we leave, but while returning, we pass them at 11:00 and 12:00. So, on the way back, we’d have to find some other place with charging. That’s something we’ll need to plan around before deciding.. I think it's worth upgrading from my Renault Duster. Since at Munnar I found it hard to find a petroleum but saw more charging stations

Regards,
Mahindra Boi

Got frustrated with them not being able to get a vehicle across to me inspite of 2 of the bookings being in the 1st minute and third one in the 3rd minute.

Further gave them 3 colour options too as a last resort.

Frankly it's fishy.

But it all happens for a good cause.

Picked up a 9 month old 2024, 5000km run ISUZU VCross. 4x4 AT Z Prestige with lots of loadings in the suspension etc. Had an eye on this for long. Got it from the Authorized dealer. 2+ years warranty remains.

Congrats on your purchase. From the pictures, I assume you bought your car from JMD Khar. I've been following this dealer for quite some time now as he has an attractive inventory.
Would you please share your experience with them? I might make a purchase anytime soon if they have the right car avaliable.

From the TBHP Review

As we know, these battery packs from BYD have high packing efficiency. Conventionally, the batteries have battery cells packed into modules first and then each module is packed into battery packs. However, the BYD battery has a cell-to-pack structure and there is no module. This helps to pack more cells in the given space. The LFP battery has an energy density of 141.5 Wh/kg.

I am not sure where to post this but the energy density got me thinking: 141.5Wh/kg is what M&M achieved with BYD cells, then how did Tata achieve volumetric density of 186 Wh/L or may be these numbers are not related? someone please help me understand

Sorry that I am not answering your question. But, I would not even compare MM Twins with Tata.

They marketed their cars as born EV, and till now delivering EV cars with rear seat bumps
Curvv charging DC charging speed is 70 kw, compared with 175 KW of MM.

In spite of having 5 yrs of lead time, and govt literally reserving the entire huge market for them, they have under delivered. They seem to have an idea of "this is enough for now", when delivering their cars.

I get it, I was not comparing the cars but the battery tech only. Both Born EV and make shift EVs still use a battery and motor. Born EVs show their strength in areas beyond battery and motor, and I am aware and hence not comparing.

The sensors are not so accurate, so the algorithm always will assume a safe clearance so as not to bump or scratch the car. Your car will refuse to move is my strong guess. All the best. Try it and let us know

Agree, also not happy with current pack2 not having the 360 camera, which is essential, while I have booked for pack 2 looking for new variant that can support 79kw and few essentail features like 360 camera and ventilated seats
