Why a disappointed Tiago EV owner has put his Altroz booking on hold

It’s quite disappointing to note the quality of Tata Motors products, as well as the service that leaves a lot to be desired.

BHPian krishnadevjs recently shared this with other enthusiasts.

Today morning I got the HV Critical Alert on my Tiago EV XT. The car's done just about 2000km and has always been charged on a slow charger. The car drives around fine, and all regen modes also work, but the HV alert light is still on.

I've called Tata's service center, Trident Motors in Kurla, and they've promptly arranged a driver to pickup the car. Hopefully, this is not the start of a long ordeal with Tata Motors.

Here's what BHPian payeng had to say on the matter:

If the car is has been running Ok, I guess its not too much to be bothered about.

Anyway do keep us updated on the developments.

Here's what BHPian ferrarirules had to say on the matter:

If the car is driving fine, i think it should be ok. Can you please share your charging graph/soc history from zconnect app?

BHPian krishnadevjs replied:

This is the SOC from the app, for the last 4 months.

Final update:

Update on my HV Critical Alert.

After 3 days of silence, after I followed up, the Service team at Trident has replied that it is an issue with the AC compressor, for which they’ve escalated to Tata Motors and are awaiting a response.

This seems highly unlikely as the AC works on the 12V battery system whereas the HV Critical Alert should refer to an issue in the EV battery - wiring - MCU circuit. Despite me telling the SA this, he is insisting that it’s a compressor issue.

I’ve written to Tata Motors customer care highlighting the issue and my concerns on the diagnosis. Nevertheless, it’s quite disappointing to note the quality of Tata Motors products, as well as the service that leaves a lot to be desired.

My father just booked an Altroz DCA, which is to be delivered next week. My father in law was planning to buy a Tiago EV. Both are now waiting to see how this pans out before taking the plunge.
