Bad Owning experience

I bought Tata nexon xza+ dual tone. Here is my feedback on service and product. Regarding product one can find enough information as to what is good. I will talk about problems I started facing from one month of purchase and service response: 1. Hot air coming from engine compartment to inside car through AC vent. This issue I realized around 20 days after purchasing the car. Have raised complaints on this and my car has gone 3 times to service center without any resolution. As per Tata service partner, we should always keep air circulating mode Off. So you can not have Windows closed and put blower on in morning drives to get fresh air in. 2. Heating of leg space region on driver side. Service visits twice. This is little more serious from safety point of driver. Tata service partner acknowledges the issue and I was told that they have reported this issue to technical team of Tata motors but still issue no feedback. 3. Average in city around 11.5. Since 2 days I have started seeing spanner symbol on dashboard near average display reading. I will be taking car to service centre tomorrow and this shall be 6th visit apart from 2 maintenance visits in 7 months. Overall I am not much satisfied with experience of owning nexon because it gives you now or then some or other issue. I have hyundai santro also and if I compare the ease of owning it is much better with hyundai. I never had any issue related to functioning for my I-20.
