Kia Sonet maintenance costs
The Kia Sonet is affordable to maintain, with the first three services free. Five-year maintenance costs range from ₹20,000 to ₹30,000, with diesel engines costing slightly more for oil. Turbo GDI petrol models require spark plug replacement at 70,000 km, keeping overall costs under ₹0.50 per km.
The following table provides a breakdown of the Kia Sonet maintenance costs:
| Number of Services | Schedule (km/year) | Petrol 1.2 Estimate | Petrol 1.0 GDI | Diesel 1.5 Estimate |
| 1st/2nd (Free) | 1,000/5,000 km | Free | Free | Free |
| 3rd | 10,000 km / 1 year | ₹2,485 | ₹3,150 | ₹3,674 |
| 4th | 20,000 km / 2 years | ₹4,840 | ₹5,505 | ₹5,698 |
| 5th | 30,000 km / 3 years | ₹4,820 | ₹5,485 | ₹5,690 |
| 6th | 40,000 km / 4 years | ₹5,705 | ₹6,554 | ₹6,898 |
| 7th | 50,000 km / 5 years | ₹4,995 | ₹5,670 | ₹5,864 |
Extended warranties to seven years/1.5 lakh km and RSA packages further amortise risks, with lifetime transmission fluids slashing long-term fluid exchanges significantly.
Tips to maintain your Kia Sonet
Keep a check on your Kia Sonet to keep it running smoothly for years to come. Here are some preventative maintenance tips to help you with the same:
Check the engine oil level regularly
Maintaining the correct engine oil level is essential for the turbocharged Kia Sonet engine. Drivers should inspect synthetic 0W-20 ACEA C5 oil every two weeks using the dipstick, ensuring it stays within recommended levels.
Proper lubrication keeps the turbo GDI engine operating efficiently, especially during frequent highway merges or spirited driving, preventing premature wear and supporting optimal power delivery and fuel efficiency.
Inspect brakes and fluid every 10,000 km
Regular brake maintenance is crucial for vehicles equipped with IMT or DCT transmissions. Checking pad thickness and DOT-4 brake fluid every 10,000 kilometres ensures that regenerative braking functions properly.
Maintaining these systems prolongs component life, improves stopping performance, and allows for smooth modulation during daily driving, particularly in stop-and-go traffic or city environments with frequent braking demands.
Maintain battery health with quarterly checks
Battery care is often overlooked but vital for modern vehicles with ADAS features. Visiting a service centre at least four times a year for terminal cleaning and voltage testing helps maintain starter reliability.
This ensures uninterrupted operation of electrically powered systems such as sunroofs, ventilated seats, and other comfort features, reducing the likelihood of unexpected failures while supporting consistent vehicle performance.
Replace air filters at recommended intervals
Replacing the engine air filter every 10,000 km keeps airflow unrestricted, allowing the turbocharger to spool efficiently and the naturally aspirated engine to respond promptly.
Cabin air filters should be changed every 20,000 km to maintain freshness and proper humidity control during hot or humid commutes. Timely air filter care improves performance, preserves engine health, and enhances passenger comfort over the long term.
Routine servicing ensures your Kia Sonet continues to perform at its best. Beyond basic maintenance, scheduled service visits allow OBD diagnostics to detect potential engine or turbo issues early.
Recording this information in a logbook can even support extended warranty claims for qualifying components. Consistent servicing protects engine longevity, prevents costly repairs, and helps maintain peak handling and efficiency.
Align and balance wheels periodically
Wheel alignment and balancing are essential for vehicle stability and tyre longevity. Misalignment can result from rough roads or uneven weight distribution and may negatively impact handling, fuel efficiency, and tyre wear.
Performing alignment checks regularly corrects camber issues, promotes even tyre wear, and ensures smooth, predictable steering, contributing to safer driving and more consistent performance on highways and city streets alike.
Practice smooth driving for better efficiency
Adopting smooth driving habits reduces stress on the DCT and IMT transmission components. Gentle throttle modulation promotes thermal balance in the clutch system, helps maximise fuel economy, up to 18.3 km/l, and minimises premature wear caused by stop-and-go traffic.
Controlled acceleration and braking not only improve efficiency but also enhance overall vehicle longevity and maintain a smoother, more comfortable ride for all passengers.
