Excellent video. I sat through the entire 1 hour. The kind of engineering that goes into a Tesla engine and it's components is mind boggling. Interesting to note that it has the ability to draw heat from so many points including the Motor, Hot coolant and the AC compressor!

Heating in an EV is a big challenge and having a good solution for managing heat is a must. Forget about cold countries like US/Canada even in a tropical climate like Kerala having a good heating story is important as the following post indicate.

Tesla's heating system is impressive but its design requires solid engineering and lots of training data to workout the control of various valves and heat exchanges. I cannot see many auto-companies, particularly in India, being about to match this and even if they designed, it would be a challenge to maintain it.

Here is the latest Update on my car. The car has been lying in the workshop for a month now and I was informed by Mahindra that it would take more time as they were waiting for an update from their overseas parts vendor. I felt it is pointless to wait indefinitely without a solution in sight.

After some discussions over the past month with Mahindra customer care, it was agreed that a refund would be issued. The ownership of the car has now been transferred back to the dealer for a refund.

What % of car cost they are going to give? also I am wondering, is the car beyond repair that Mahindra gonna bare the cost?

Damn! That bad, eh?
They didn't offer to replace with additional warranty?

XUV400 uses LGChem and Farasis as supplier, the latter of which was also the supplier for the battery for the Incheon EQS fire.

Considering the recent developments, Mahindra maybe taking the conservative but safe route here.

Yes, 100% of the cost of the vehicle.

There was an option to replace this for a new car but it didn't seem like a safe bet.

Yes, this particular car had the battery by Farasis as confirmed by Mahindra. We need a rule where in Auto Manufacturers have to declare the battery pack make.

[KeepItSimple]

Mahindra provides the battery information during the PDI.

I have the LG chem battery pack.

Very interesting read. I was considering a 400 EL pro with the 3L discounts doing the rounds. Waiting and watching.

Us Indian customers are in a tough spot - between a rock and a hard place - 400 v/s the nexon. Well, the nexon has LFP batteries which inspire confidence but then that's the only part that does. If I were to be picky, I feel MnM with teething troubles is FINE as long as we're talking about ICE vehicles. This over reliance on third party vendors especially for imported parts like battery packs (and the clear delay in the case of the OP's 400) worries me in terms of two things -
1. In house know how seems limited. I have had my stereo and AC changed in my Thar as well. At least both suppliers were based in Noida so things moved fast. Days, not months.
2. Speculatively, supply chain issues say 5 years down the line. Seeing as how, often, harnesses (poor example, but hear me out) change, I don't know if we'll be able to get battery and related swaps later. Early adopters get bashed the most from what I've seen. For instance, I cannot just the Dimming IRVM for the Scorpio N on a 3 month old car cause they've changed the harnesses. How will this translate to low-volume cars like the 400?

One argument to continue point #2 above is that I am comparing
i. a harness change for a new feature
ii. with legacy part availability.

I sustain that revised parts often go with different harnesses. 5 years down the line it will be exceedingly difficult to get an older harness. Perhaps a module is updated that only works on a new harness. Some quality of life improvements can often be interpreted as 'new features' which could bring along better reliability as well. I often see some features not being made available for initial lot buyers in software and/or hardware.

The final nail is that often the parts management system in the MnM parts shop is outdated. I tried, with accurate part numbers, to order 2024 Scorpio N parts for retrofit to a 2023 model. We copied exact model numbers and I check with two parts shops - neither of them had half the SKUs listed, as parts that could be ordered, let alone, in stock. Three simple things that are available in tens of thousands of cars already on the roads - dimming IRVM, air cooled wireless charger and some console parts. I digress, but I hope the hesitation is conveyed. There is, further, no scope to go to local FNG for an EV.

[Mortis]

It might not be applicable in this case but all EV owners and those using the car should make them selves familiar with the location of the battery safety cut off as well as how to access and activate it.

Glad that the OP got his money back. Is XUV 400 worth considering?

Thanks for this info. What's the average range you are getting on your car? I am wondering if the LG pack has any advantages in this regard.

Considering the offers, it's a great buy. It is bigger and feels better put together than a Nexon. Over long distances, it is so much for stress free than an ICE in my experience. Power on tap being the best highlight.

[deep_bang]

The fact that Mahindra is refunding the cost goes a long way in inspiring confidence about buying a Mahindra EV. Granted the fire/smoke episode is dangerous - but this could easily have escalated into an unnecessary support nightmare - but in the end, reasonably fair considering Mahindra had their own challenges dealing with other companies.

The average that I get is 157 watt hour per kilometer which translates to a range of about 250 km. My usage is 100 per cent city with always on ac use, temperature set for 22 degrees with blower speed of 2 or 3.

The car is great, spacious with a great electric drive train. It's 'business class' according to my wife who drives the comet ev.

We use home charging for both cars.

On the LG battery pack I would refer you to the following.

Are China-made batteries being fairly criticized for EV fires?

https://m.koreaherald.com/view.php?ud=20240814050564

With about 40 per cent of the EV going to the battery pack, the EV buyer should do due diligence on the battery supplier even for a higher end vehicle like Mercedes!

Comfort level for the buyer is higher with a top rated battery supplier like CATL or LG chem.

Going forward Mahindra needs to shed the NMC battery for LFP just like the case of the MG ZS ev.

Happy driving!

Very impressed with how Mahindra was quick to resolve this and refund the money. A stark contrast from some of the horror stories I've read here and it certainly makes me open to buying a Mahindra in the future.
