Is buying the Sonet 1-litre TGDi DCT model a good decision, considering the reports about HPFP issues?

There have been some reports of high-pressure fuel pump (HPFP) issues with the 1-litre turbo-petrol engine on the Kia Sonet and Hyundai Venue. While these pumps are typically replaced under warranty, the process can still cause inconvenience and, in some cases, minor expenses.

If you’re looking for a more reliable alternative, the Kia Sonet 1.5-litre diesel automatic is smoother and more enjoyable to drive than the 1-litre TGDi DCT. The only caveat is that you’ll need to regenerate the diesel particulate filter (DPF) periodically by driving at a steady speed for an extended stretch every few weeks.

Hi, my budget is Rs 15-16 lakh maximum. I drive around 3,000-3,500 km per month, of which roughly 2,000 km is on highways, and the remaining 1,000-1,500 km is in the city. I am looking for a low-cost, high-value-for-money car. I have no issues with diesel. I need comfort, good power, strong torque, and decent ground clearance.

Buy the Mahindra XUV 3XO diesel. With your 2,000 km of highway every month, its strong diesel torque keeps overtaking easy and cruising relaxed, and it’s one of the few that still gives you real value under Rs. 16 lakh.It rides comfortably on broken roads and speed breakers, has proper ground clearance, and feels secure at highway speeds. The diesel’s running costs will stay low at your mileage, and Mahindra’s pricing of the mid trims means you don’t have to stretch for the useful bits like cruise control and six airbags. One thing you will have to live with is that the boot is smaller than most rivals, so fitting two large suitcases can be a squeeze.If you absolutely want an automatic for your 1,000 to 1,500 km of monthly city driving, options like the Kia Sonet, Kia Syros and Hyundai Venue offer smooth torque converter automatics in this price range and are very easy to live with in traffic. However, if fuel efficiency is a priority, we would suggest sticking to a manual, as it will be both more efficient and more affordable.If you’re fine with a manual, the XUV 3XO diesel is the sweet spot for torque, comfort, ground clearance and low running costs.

My dad wants a big SUV feel with status but under 20 lakh. He likes the Scorpio N, but I feel it will get outdated soon. We tried the Tata Sierra and Kia Caren but are still confused. We want good mileage and a full automatic. Our current car is a Kia Sonet, so driving should be on par or better.

The Mahindra Scorpio N is due for a facelift later this year, so if your father likes it and doesn't mind waiting, it could be worthwhile. However, while it has great road presence, it won't meet your other requirement of good mileage. The Scorpio N is a large, heavy, ladder-frame SUV whose focus is on strong performance and responsiveness, rather than mileage, so prepare for much lower figures than what you get in your Kia Sonet. Moreover, owing to its top-heavy ladder-frame layout, it won't drive as well as the Sonet, at least in terms of handling and sharp dynamics. What you get instead is a commanding driving position and a tough, robust feel from the driver's seat. For a good mix of road presence and driving dynamics, check out the Tata Sierra. You'll get a decently feature-packed variant around Rs 20 lakh. Also, it is the most spacious in the class, and the turbo-petrol and diesel engines come with a smooth torque-converter automatic that works well around town and on the highway. Moreover, since it is a monocoque SUV, it has more car-like driving dynamics, easier manoeuvrability, better ride quality and better refinement. For your requirements, the Sierra is the better pick.
