Kia Seltos

The Kia Seltos is a very good option, and the good news is that there is a new Kia Seltos version launching in only a few days. It is likely to carry forward the powertrain, and that means the torquey diesel engine will also be available. 

The new model will also get feature additions and a fresh new look, so it's worth waiting for. Also, there is no issue with going for a long drive three times a week in your car. 

In fact, since diesel cars feature a DPF (Diesel Particulate Filter), it is recommended to take them out on long drives and get the engine to burn off the soot collected. Driving long distances often will not cause any issues. 

The Hyundai Creta and Kia Seltos are mechanically identical, so your choice should boil down to which SUV's exterior and interior you prefer and your proximity to the brand's touchpoints. 

It's worth noting, however, that the Seltos gets a heads-up display, which the Creta doesn't, while the Creta gets a 'boss mode' for the front passenger seat, which the Seltos misses out on. 

This isn't a problem with Kia cars alone. All engines equipped with a DPF have to undergo a DPF regeneration cycle regularly. This typically happens automatically when the exhaust temperature is high enough, typically when the car is driven for 20 to 30 minutes at speeds around 60kph and above, typical of a highway drive. 

If this does not happen, the car will alert you via the instrument cluster, and you will have to conduct a complete cycle as instructed. The failure can occur if the warnings are ignored or due to some manufacturing defect. In any case, it is good that the dealer is replacing the DPF under warranty. 

Going forward, if you have frequent short trips, try and include one 30-minute highway drive at least once a week. Also, avoid long idling periods, make sure you pay attention to all alerts - in case you have ignored any - and fill fuel from a reputable pump.
