It seems Tata has changed instruments cluster. Ziptron badging has been done away with it.
Does it mean 2024 Tiago EV is using a new Battery powertrain architecture like new gen Tata EV?

I will report back once the car is back in 3 days.

But one thing my driver told me is that apparently many Tiago's are coming back with the same issue here.

A quick update here. Both the front tyres got replaced, the dealership offered some discount but Apollo just refused saying it is normal wear and tear. The tyres had worn out in less than a year and around 9k kms. It is absolutely appalling. Moreover the Apollo guys got the wrong tyres installed "by mistake", they fitted someone's wagon r tyres in mine and delivered the car. This of course got corrected the next day. The steering assembly has been replaced along with both front shock absorbers now. The QC in these vehicles is absolutely appalling. Tata needs to stop pushing prototype vehicles to us. I extended the warranty for 4 more years after this.

Yeah I have same question, or is this new change just a part of software update ?

He called his engineer who apparently asked for some data. The mechanic says that he requires 2 days to collect this data. This data will be forwarded to the engineer who will decide the next course of action.

I faced the exact same issue in my Tiago EV after 22K on Odo. A faint humming/ "drrrrrrr" sound was coming for last few days. Range was also reduced & I was worried about battery degradation also.

During the 4th paid service, I pointed out this noise & it was identified as abnormal sound from motor/ drive. Videos & data was collected & sent to the Tata engineer. I was asked to come after 2 days & get the e-drive replaced. I went back after a week & motor was replaced within 4-5 hours. Car is back to being silent & with the new motor, range is also improved. SOH is 99% after 23K kms in 1.5 years.

In EVs, motor number is captured in Engine Number field & it has to be correctly updated in the RTO & insurance records. My service advisor has no idea & he mentioned that they have never updated the motor number in past. How did you manage to update the new motor number in the RTO & insurance records? Any info on this would be really helpful.

Tiago EV LR XZ+ Tech Plus bought in March 2023. It was one of the 1st cars manufactured as the vin shows December 2022.

After close to 14,000 kms I have encountered the dreaded HV Critical Error but not just that...

Any help or advice would be greatly appreciated. Thanks.

Update:-

So i got the car charged to 100% and tried using it again. Everything worked fine initially.
However this time when the car hit 46% SOC the limp home mode began flashing followed by the HV error. I was on the W.E. highway on my way to Oberoi Mall so I carried on in the hopes that I can charge there.
Just as I entered the basement parking the car cut out. After cycling the iginition on and off it finally started long enough for me to park at the charger. Charging was done till 82% SOC and then i left for home.

The following day I immediately scheduled an appointment to bring her in to the ASC at Worli.
Shockingly the appointment date I receieved was for the 9th of September, almost a month away. The reason, huge load of EVs at the service centre. This was also true of the other ASC's i enquired with.

Sadly it seems that while TATA is selling EVs like hot cakes they are struggling to service and maintain them.

Finally the appointment date arrived and having charged the car to 100% SOC the previous night I set out for the Worli ASC which is about 40kms from my residence. Luckily dropped off the car with no issues apart from the usual long wait to meet the service advisor. They said that they will check the battery condition etc. and get back to me.

Just got a call a few minutes back saying that the entire HV battery pack is going to be replaced. Timeline approx is 10 days.

The battery pack will be a refurbushed unit according to them and the original battery warranty will remain the same as before. They have asked me to pick up the car and use it but the SOC should not go below 50%. Once they receive the replacement battery pack they will ask me to come in again.

Is this ok? Should i be asking them for anything else specifically?
I have asked them to send me the same in writing via email.

So my Tiago EV had a smashed windshield due to a big stone impact. My insurance is with New India and the service centers closeby do not have a cashless tieup. Since Tata appears to very sensitive with EV warranty and also that my windshield has the sensors for wiper/headlight, i did not want to go with 3rd party centers. This is the first time i will be filing a non cashless claim. Let's see how it goes.

My other immediate concern right now is if my insurance is adequate and covers the main battery. I opted for Zero Dep and RTI but i find no mention of the main battery being covered. The only reason for me to go with New India is the very low price and I'm worried battery claims might end up in denial. With the way HV Critical alerts are popping up, I've started to think that HV critical alerts are now a question of when and not if. Also another thread indicates that Tata has started denying warranty for even minor cosmetic damage to the battery container and asked the customer to claim warranty.

I have searched online for battery protect covers but could only find a battery protect cover being provided by Iffco Tokio but that cover is only for the first 3 years of the vehicle

Can anyone help with which companies are known to provide comprehensive insurance for the high voltage battery of an EV? The recent BYD Seal fiasco with battery claim being denied on another threadindicates that EV insurance might be something that a lot of EV owners might have not thought through. I plan to switch to an alternate provider which provides a through battery protect rider.

My Tiago's software was updated couple of months back (during service), and since then I noticed that the car would start to regen pretty quickly (98% SoC). Previously, I think it was from 95%. Also the mode selector lets me switch to Neutral and back to Drive while the car is moving. Previously, I think I had to get the car to stop before switching from Neutral to Drive.

Wish the service advisor knew about the changes being made and informed the customer before delivering the car back.

So my windshield was replaced in about 4 days. This is despite the service center having the windshield in stock. The price came to approx 10k which i will have to claim from New India.

Next would be the reapplication of 70%VLT Garware Icecool films on the windhshield. Having driven two summers with this film, i simply cannot go back to a windshield without a film. Prime benefits - Heat rejection, glare reduction from oncoming high beams, sunglasses no longer required while driving.

Post the windshield film would be to reattach my 70mai 810. Will keep putting updates. Any queries do let me know.

I still am worried on the battery coverage on my insurance. Anyone who has got written coverage for battery? Will be helpful to have details.

So i got my Tiago.ev serviced and while being services, I enquired about my HV battery health and how I feel, its not giving me enough backup. My battery SOH was found to be around 94% after running 52k kms in 18months. Is it normal?

My tires got changed at around 45k mark. My LV battery has given up and is not functioning properly. What is the warranty on these ?


TIA for your replies.

6% degradation is a bit higher for 52k if you are doing mostly slow charge. Does this mean tata feels 16% degradation or 84% SOH for 1.6L km is normal ?

I too think this is not normal, but i have never got the HV critical alert. So I am vary of getting the battery changed. The SA did tell me that this degradation is normal, but he might be trying to avoid my questions further.
Any advice on whether I should go and get it checked again and raise this issue, or is it within permissible limits and i should not worry much?

As advised, this degradation looks higher than normal, but then your usage also appears to be quite high ? What percentage of your charging has been on DC ? Mine was 99% at 22k kms in approx 15 months.

Mine has been charged 99% of the times on slow charging. very rarely have i fast charged it, that too, i don't remember ever in succession.
But my car is put on charging every night. Most mornings we have 100%, and use the car around 50-150km.

Regards

Maybe that's causing the degradation. LFP has the most deg when regularly charging from 80% or so to full charge, from what I remember reading/learning about this

No sir that is NMC which needs to be within 20-80 for optimal Performance. LFP on the other hand needs to always be charged to 100% for cell balancing.
