Hyundai Motor India — Brand new santro cng sportz engine problem

Hello All,

I purchased my new santro cng sportz executive model on 14th feb 2021 with lots of excitment and after 15 to 20 days it start whistling.
When ever i push accelerator it start whistling and pickup is zero, consuming huge amount of petrol and cng.
Went to service centre at shamli (U.P) location from where i purchased the vehicle.
They analyzed it but didnt get the root cause then they send me to new service centre at muzzafarnagar(U.P).
They did the same analyze the vehicle and did not get the root cause after 3 to 4 days they told me that we are looking by changing regulator of cng then we will analyze the engine power again.
Now its a long time there is no regulator get changed not even get any update till now.

One more thing my grandfather purchased maruti suzuki wagonr before 6 months and that vehicle is running super.

Worst customer support, worst vehicle quality.

Now nobody is here to support me, i have spent 6.60 lakh rupees and sitting like a fool.

Thanks,
Ashish Malik
