Range is not giving on drive mode.

I am owning Tiago EV Long range XT. Range claims are defined to 315 kms. In every charge it shows me 130 kms to 170 kms maximum range in last 50 days. Actual range running is around 150 kms average with AC on and regen 3 with city driving. Depreciation is more than 50%. Talking about quality. While driving on first day.. the driver breakpad catches smokes.. which can be visible on wheel cover. Indicator was not turning off after taking back steering back to normal. The two problems were fixed, by replacement of both the parts. Now my vehicle is in service center from past 7 days for motor replacement.
