The Kia Sonet faced strong competition in the small SUV market. Its closest rival was the Hyundai Venue, as both cars used similar engines and parts. Other top competitors included the Maruti Suzuki Brezza and the Tata Nexon, which were very popular with Indian families. The Mahindra XUV300 also fought for the same buyers by offering good cabin space and safety features. Some buyers looked at the Nissan Magnite and Renault Kiger because those cars cost less money. This model competed in a busy space where every brand tried to offer more for less. The Kia Sonet had to match the prices of these other SUVs, which usually ranged from 7 lakh to 15 lakh rupees. Many rivals also offered petrol and diesel engines to attract different types of drivers. This car had to work hard to stay popular in such a crowded market.
