Kia Sonet Extended Car Warranty

What Happens After the Kia Sonet’s Factory Warranty Ends

The Kia Sonet sold 10,736 units in 2025, ranking twelfth among South Africa’s best-selling models (The Citizen). The compact crossover launched here in 2021, gained a 1.0 turbo in 2022 and was facelifted in 2024, so the earliest cars are now around five years old.

This page sets out the factory cover, how the 1.5 and 1.0 turbo versions and the 2024 facelift differ, the weak points reported so far, and how an extended motor warranty fits in.

Kia Sonet Factory Warranty and Service Plan — What You Started With

Per cars.co.za, the service plan was cut with the facelift, and its sources disagree on the exact distance, so check the terms in your booklet. Whatever the exact figure, the service plan ends well before the warranty does, so servicing becomes an owner cost during the warranty period.

Kia Sonet: 1.5 vs 1.0 Turbo vs 2024 Facelift

The Sonet launched with a naturally aspirated 1.5-litre. A 1.0-litre turbo with a 7-speed dual-clutch gearbox (DCT) was added in July 2022. The 2024 facelift reshuffled the trims and added features.

Known Kia Sonet Problems to Date

We found no South African buyer’s guide with a documented mechanical fault list for the Sonet, and no recall. We quote no repair costs. The weak points reviewers and cars.co.za report are below.

Power loss at altitude (1.5)

cars.co.za says the 1.5-litre loses about 17% of its power at Reef altitude, which matters for Gauteng buyers.

Turbo lag and ride (1.0T)

Top Gear noted slight turbo lag below about 2,500 rpm and a firm suspension that struggles on rough roads. The dual-clutch gearbox is also a more complex unit than the 1.5’s CVT or manual, with no documented SA fault record yet.

Safety specification

Entry-level Sonets have only two airbags, while several rivals have at least four; the EX+ and SX have six. If you are buying used, check which specification the car has.

Recalls

We found no Sonet recall in the sources reviewed. Check any car by VIN with a Kia dealer.

Compiled from price lists, reviews and sales reports up to October 2026. Sources: cars.co.za (Sonet overview); Cape Argus (turbo launch); Top Gear (1.0T review); The Citizen (2025 sales). No documented fault list or recall for the Sonet was found. Details can change — confirm with a Kia dealer.

Why Kia Sonet Owners Choose an Extended Warranty

The Sonet’s 5-year unlimited-km warranty is strong, so extended cover matters most for the 2021–2022 cars now approaching the end of it, and for owners who want to keep the car beyond year five. The shortened service plan also means servicing costs come early. An extended motor warranty keeps repair costs predictable. It is subject to its own terms and exclusions — ask Cheryl what applies to your Sonet.
