2011 Kia Sorento – Click above for high-res image gallery

The National Highway Traffic Safety Administration has opened an investigation into the 2011 Kia Sorento for possible driveshaft failure that results in a sudden loss of power. According to NHTSA, there have been four complaints about the intermediate driveshaft and another five alleging that the power loss was due to a transmission failure which may be related to the driveshaft issue. The investigation will look into 50,000 2011 model year Sorento CUVs.

The second, separate investigation concerns possible corroded lower control arms on the 2002-2003 Subaru Impreza. According to The Detroit News, there have been seven complaints alleging that the control arms on the Subaru can break at more than 50 miles per hour, with two claimants saying that the failure sent their car outs of control. The Subaru investigation affects 84,000 Impreza models.

Though no recall has been ordered yet in either case, Kia has reportedly issued a technical service bulletin to address a clunking or squealing noise from the intermediate driveshaft.

      Isn't it amazing how "investigations" on foreign cars have INCREASED since Obama illegally backed GM and Chrysler?

      Those are some pretty serious issues. Hope they get em fixed/resolved soon.

      The 2010 Santa Fe's (which share the drivetrain and chassis with the Sorrento) also have widespread transmission failures. I wonder if that will be looked at as well.

        The high failure rate is probably related to the fact that these vehicles are heavier vehicles using Hyundai's newish in-house six speed. I was wary when I first heard that they were going to switch to their own in-house gearbox because they had originally switched to Aisin transmissions because their own automatics were kabooming and costing them quite a pretty penny on those 10 year/100,000 mile powertrain warranties. Figured it'd probably be a good idea to wait a couple years to see how their attempt at bring it back in-house fares.

        On the bright side it seems like most of the complaints are with the heavier and larger vehicles like the Santa Fe and Sorento. I remember reading that it was a very compact and light unit compared to the previous transmissions they were using, but I'm guessing that whatever they did probably made the transmissions less robust for dragging along the big crossovers, they seem to be holding up better in lighter vehicles like the Sonata but you won't really know how good long term reliability is for another couple of years.

        The good thing though is that Hyundai will have to cover most of these transmissions though, since their powertrain warranty has them on the hook for quite a while.

      Now I've got an excuse to get aluminum control arms.

      Carmakers have been putting drive shafts in cars for a long time. You would think they would have the hang of it by now.

      I am old enough to remember when they just swept this sort of stuff under the rug. Good to know somebody is making them do the right thing, sometimes kicking and screaming all the way. It would be even better if they engineered, tested and built the cars right in the first place.

      I'd be rather interested in hearing what happens with the Subaru investigation.

        I had a 2002 Impreza that lived its whole life in the Northeast, that I sold last July. Maybe I just dodged a bullet?

        Honestly, this doesn't surprise me much. After owning it, I got the impression that they rushed the design work on the 2002's. Lots of crap that got redesigned in the next 1-2 years on that car.

        Given that you have a bugeye in your profile picture, I am sure you are interested.
