2018 Kia Sorento Pricing and Specs

The Acadia doesn’t boast a diesel engine, so economy could be an issue for your daughter; also it’s only a little longer than the Kia Sorento, so space could be another problem. A better choice would be the Mazda CX-9.

That's not easy to answer without knowing your situation in more detail, but if shopping new, I'd recommend the Sorento. 

It's a fresher overall design with more smart thinking behind it, and a four-year longer factory warranty. 

It offers the option of diesel if you prefer, but I'd be choosing the petrol for overall performance and refinement, with still decent real-world fuel efficiency. The petrol V6 Sorento is only available in two-wheel drive though. 

Good luck, and keep us posted with your journey, 

So many things affect road noise, which makes it difficult to fix. There’s the road surface itself, the tyres, and the noise insulation in the vehicle. The Honda CR-V might well be quieter, but could still be noisy on the roads you drive on. If the road noise is the thing that is making you switch vehicles, then it might be worth talking to a tyre dealer about a tyre that might be quieter than the ones on your Kluger. If you want to go down that road, you could try a Mazda CX-5 or CX-7, a Kia Sorento or Sportage, Toyota RAV4.
