Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Sorento 4-cyl

  • 26,982 miles


While driving the vehicle and while pressing the gas pedal the vehicle starts to come to a stop as if the gas pedal is not being applied. I have to release the gas pedal and press it again for the Sorento to respond and continue to accelerate. I took it to the dealer and they have no clue as to what is the problem. They reset the computer and released the vehicle to me but the problem persists.

Driving from palm springs to los angeles on highway 10, a very loud clunk heard beneath the drivers seat and vehicle lost power but continued to rev. Slowly recovered. About 10 minutes later, at speed of 65 in traffic on highway, another loud grinding clunk heard somewhere beneath driver's seat. Vehicle again lost power but continued to rev. Best way to describe is that it felt like the car was suddenly dropping from 5th gear to 1st gear. But the gear shift was not touched. This happened in traffic on a major highway. I see there are dozens of similar complaints registered on this site. Please take action before someone is hurt.

Cruise control broken for 3rd time. Cruise control does not work, has already had cruise control switch replaced once. Taking into dealer for third time and ironically, the day we picked 2011 Kia Sorento up to have the cruise control fixed for the second time, it did not work with dealer stating "could not duplicate customer's concern." What if we all did our job that way" is this site, paid for by us citizens, just for blogging or does the national highway traffic and safety administration have any teeth" its about time for a recall on the 2011 Kia Sorento for transmission, sudden acceleration, cruise control, steering - pulling to the right, and other problems the 2011 Kia Sorento has that are dangers to the public at large.

I was traveling at approximately 70 mph and my tachometer stopped working and I started losing speed. The car would not shift. I was able to move to manual shifting and resume my speed. But the tachometer continued to read "0".

Vehicle pulls to the right and has since day one. Dealer states "we cant duplicate your concern", yet when we picked up the vehicle (from the cruise control breaking, the vehicle again pulled to the right. We did not say much after until reading about dozens of other vehicle owner whom experience the same problem. When will the national highway transportation and safety administration do something about it?

Sorento 4-cyl

  • 16,347 miles
After completeing the second NHTSA complaint #10377110 last evening on our 2011 Kia Sorento, my spouse came home from driving the 2011 Kia Sorento (with two previous transmission complaints) and informed myself the vehicle now accelerates on its own!!! my spouse stated "the engine started reving all by itself" so I hit the brakes. She stated the vehicle's brakes did in fact stop the vehicle and she was able to drive home safely with no further incidence. Please do something about the Kia Sorento before someone is hurt. We will no longer drive the vehicle for any reason.
