Tata Tiago EV: Tata Dealer refuses to install electrical accessories

I'm specifically looking to get the rear parking sensors installed as the XZ+ Tech does not come with Reverse Park Assist

BHPian Mile10 recently shared this with other enthusiasts.

Just checked with my dealer, apparently you can't install any electrical accessories on the EV Car as it will impact warranty. I'm specifically looking to get the rear parking sensors installed as the XZ+ Tech does not come with Reverse Park Assist Audible Sensors; it comes installed only with the Camera. Surprised that Tata decided to offer only the camera on the top end variants.

Here's what BHPian coldice4u had to say on the matter:

I believe this is understandable. Considering most of the issues reported for Nexon and Tigor have been electrical in nature, i would be very wary of any kind of accessories. I myself wanted to get a dashcam and HIDs for the car, but i guess I'll hold off.

Also has anyone here got a car delivered?

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

Dealers will always say that, they just want that you buy the accessories from them at FAT margins.

The 12v electrical system that runs the lights, indicators, reversing camera etc is the same as the regular petrol Tiago, or any other car. You can install any accessory like reversing camera or dashcam safety as long as proper connectors are used and wiring is not cut.

Here's what BHPian guptad42 had to say on the matter:

This looks like fake fear mongering to me. Yes, I understand we are (and should be) vary of tinkering with the LFP EV battery electrical system.

But, like most EVs, tiago.ev also has an additional, ordinary 12V Lead acid battery for accessories and headlamps etc. So, it should be possible to install the usual electrical accessories without touching the main EV battery and motor driving electrical systems at all.
