Owner reports
Selected complaints filed with NHTSA by 2017 Kia Sorento owners, lightly cleaned up (personal details are redacted by NHTSA).
while traveling about 30 miles per hour a car in front stopped. When I applied the brakes the abs locked up and caused my car to skid in to car in front. I had plenty of room to stop but as the policy report shows there was kid marks and car did not stop .
I own a 2017 Kia Sorento SX 3.3L V6 FWD with 68,000 miles and full documented service history. The HECU (Hydraulic Electronic Control Unit) failed, disabling the ABS and electronic stability control system. This is a known defect covered under Kia's settlement for some Sorento vehicles with identical HECU components. Despite the same defect occurring on my 2017 model, it was excluded from the settlement without justification. I paid out of pocket for the HECU replacement which cost $2645. This is a serious safety defect affecting the braking system. I am requesting NHTSA investigate whether the some additional 2017 Sorento models should be included in the existing settlement or subject to a separate recall given the identical nature of the defect across model years.
After using AutoBrake while driving I turned off the engine without turning off the Autobrake system. The Electronic Parking Braking System {EPB] engaged. When I turned the car on again I could not disengage the EPB. After trying everything recommended in the owners manual I called the Kia dealer and they had no suggestions. I called for a tow to the dealer. After they examined the car they informed me the system (cables & EPB system) needed to be replaced. I was lucky that the. failure accrued after I had parked and not while in motion. I have @41480 miles on the car & had only started using auto brake within the last year so I think there is a connection since the manual advises to turn auto brake off before turning off the car - not an intuitive action.
Within the last 6 months the EPB Electronic Parking Brake system engages and will not disengage leaving me stranded 3 separate occassions having to be towed to the dealership twice. Now, the KIA dealer tells me the system needs to be replaced. The dealer originally acknowledged issues with this system and that there is no fix, or recall, at this time. Such a basic function should work on this vehicle without incident and certainly should not fail under 100,000 miles. It is dangerous and can put families at risk when the vehicle locks up and will not move from its spot. Replacement of this sytem is expensive and unreasonable. There are numerous reports that can be found online.
I was driving on a highway where maximum speed limit was 65miles. Suddenly my car stalled and restarted again and post that i had a warning for Check AEB, auto hold was disabled and Traction control was enabled. For a brief moment, i lost steering which may be a result of the stall but then i regained steering. This has happened 4 times in the last 6 months. I stopped the car by the road, turned off the engine and restarted the car. The dashboard still showed the same warnings. I again turned off the car, opened my drivers side door and closed it and then restarted the car. The warning signs went off and then there were no issues post that.
On March 14, 2024 at approximately 11:40, while driving on a private driveway, which had no other cars or pedestrians on or near it, my vehicle performed its own emergeny braking effort to bring the car to a stop. The standard KIA Emergency Braking warking text displayed on the dashboard declaring the incident. However, no other vehicles or pedestrians were in hundreds of feet of the vehicle or presented a potential obstical that may be crossing in front of the vehcile.The car was traveling approximately 25 MPH and came to a complete stop. It felt as though the engine had frozen and all the wheels locked.
I was driving down a country road, and suddenly the engine stopped working, all systems shut off, and dash started flashing. Luckily, there was no one around me, and I was able to coast to a stop. However, it would have been terrible if this had happened on a busy road. Nothing worked including brakes. Had the car towed to the dealership, since we were just over 100K miles they would do nothing, and said the only thing we could do was put a new engine in for 20K. We're going to have to sell the car for a loss of 5K, as we can not justify putting a new engine in an unreliable car.
The shift release has been replaced for 2017 kia sorento but now it is traffic light switch causing one of my car problems. In gas I spend 40 dollars a day for less than 110 miles of driving even with an full synthetic oil change just done is problem two. The speedometer is off by 3 to 5 I have had bmv and officers do their test on vehicle along with the head and tail lights being replaced every 6 to 8 weeks what am I to so with a vehicle that I am still paying on.
The speed sensor that works with traction control /stability and abs has malfunctioned twice and has had to be replaced and 2 seperate occasions. The first time was when it only had 22,000 miles on it so that leads me to believe it is a malfunctioning part. Our abs and traction control do not operate properly and is ridiculously expensive to fix. Both lights are on.
The car gets stuck and will not shift out of park. I've had to use the manual override. And when the ambulance came to my house, I could not move my car out of the way fast enough and this delayed emergency response team. I thought it was a one time fluke, but it started happening again this week (4/1/26) Every time I use the car. This cannot be safe.
