The come-hither 2012 Kia Rio has been bolting off dealer lots for obvious reasons that go beyond its $14,350 price. One of its noteworthy features for the U.S. market, especially for the segment, is stop/start, which Kia calls ISG for Idle, Stop & Go. Media feedback, however, has convinced Kia that ISG is not quite ready for prime time, so it's been sent back to the engineers for tweaks.

The same system is also available on the Kia Soul, and that hatchback will be going without for the moment, as well. Apparently, some reviewers found the system's engagement rough. Kia didn't give details about the move, either what might have caused the perceived roughness or what remedy it will use to fix it. If you're holding out for ISG on your Rio or Soul, which is available by checking the special Eco options package, a Kia executive said it will now be arriving in the second quarter.

      I hope they work out the tweaks.

      It's probably no worse than just about every rough engaging Honda system I've ever tried. They work great new, but later on during the life cycle of the vehicle, the electric motor doesn't seem to be able to smoothly engage and add power. Instead provides a mild but unsettling jolt. The Civic Hybrid and Accord Hybrid more notably. Haven't seen any 50,000+ mile Insights yet, so the verdict is still out on those.

      Good for Kia acknowledged a problem and fixing it before selling it. Just too bad they had to let the media tell them what was wrong.

        Well better the media than their customers. I don't see anything wrong with getting feedback from some people with nothing to lose or gain before letting paying customers get a hold of a product.

      Lol give the new Malibu Eco a try. It feels like a 15 MPH impact when it kicks back on.

      Stop/start is not the answer to oil dependence. Just a temporary solution, like hybrids in general. I don't care how good the starters for these stop/ start systems are supposed to be. It still can't be a good thing for the engine to have to shut off, and then crank up again at least several times throughout someone's commute. On top of that, it's apparently not even that smooth of an event. Personally, I'll never buy a car with this technology on it. Don't trust it.

        The permament solution are electric cars. Lithium ion battery prices just have to come down and longevity to go up a bit and everybody will buy one.

      wonder who the media feedback was from

      The nice thing is that Kia must have used the stop/start system to get their 40 mile per gallon rating from the EPA. We own one of these new and right now,it's only getting 32 mile per gallon highway-25 city. I've just put in Mobil 1 0w20 high fuel efficiency motor oil and I hope that helps or we may get another more fuel efficient vehicle to replace this car and never buy another Korean car again. And the poor mileage is a real shame because the car itself is built great and the six speed transmission is a work of art. Anyway,we will see.
