What 107 owners told NHTSA about the 2023 Kia Sorento Plug-in Hybrid

Vehicle exhibits repeated brake pulsation and vibration under normal braking conditions, affecting braking performance consistency. The issue began at approximately 10,000 miles and has progressively worsened. The vehicle currently has approximately 30,000 miles. The pulsation is felt through the steering wheel and brake pedal during moderate braking from highway speeds and occurs consistently across multiple driving conditions. The condition is significantly more pronounced when using the vehicle’s adaptive cruise control system. During normal operation, the adaptive cruise repeatedly applies the brakes automatically, and this consistently produces increased vibration and uneven braking response. This indicates the issue occurs during normal vehicle operation rather than abnormal use. The repeated pulsation creates inconsistent brake feel and may affect stopping performance, particularly during repeated or sustained braking events. This raises concern regarding braking reliability and stopping consistency, especially in traffic conditions where adaptive cruise control is actively managing following distance. The condition has steadily worsened over time and is present during routine driving. It is not limited to high-speed or heavy braking scenarios. A manufacturer Technical Service Bulletin (TSB CHA126V) exists for this vehicle model addressing front brake disc judder. The symptoms described in the bulletin match the condition experienced in this vehicle. Given the early onset, progressive nature of the issue, and the involvement of system-controlled braking (adaptive cruise), this condition appears to be related to component performance or design rather than normal wear. Kia response .. Dear [XXX] , Thank you for contacting Kia Customer Care. We do not see that bulletin related to this VIN, as such, any repairs recommended would be the responsibility of the vehicle’s owner.

I purchased this car with approximately 22,000 miles on it. I have had to have OEM rotor resurface / replacement at the dealership approximately almost every oil change or about every 6,000 miles for about 30k miles (2 replacements, 3 resurface in an 18 month period). They sent out a Kia engineer last time it happened.

UNKNOWN However multiple times the front end of the vehicle starts shaking when I try to break up especially on the highway. The dealership claimed to have repaired it once and shortly after it happened again. When I took it in they first looked and said the parts was ordered but nothing was done then came back and said oh yes it was done then refused to fix it without a charge so I had to pay to repair it since I feared that the brake would give out if I drive it. The other issue was the check engine light just popped up check engine while driving on the highway, when I take it in they are stating that I may have left the gas tank open which is absolutely false. They cleared it but could not or neglect to explain why it was on. All these incidents occur while on highways never in the general local areas.

The contact owns a 2023 Kia Sorento. The contact stated that while driving 55 MPH or higher, the vehicle was vibrating abnormally. The contact stated that while depressing the brake pedal, the brakes seized with an abnormal sound coming from the brakes. The vehicle was taken to the dealer, and the contact was informed that the vehicle was included in an undisclosed recall related to rotors, and the rotors were replaced under the recall. However, approximately 2 months after the repair, the failure reoccurred. The vehicle was returned to the dealer, and the contact was informed that the rotors had failed again and needed to be resurfaced. The dealer started to resurface the rotors, but the contact decided to stop the process. The contact researched and determined that rotors needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was approximately 12,000.

The car is accelerating without anyone pressing down on the gas, not accelerating when our foot is on the gas, jerking unexplainably and the emergency brake warning is coming on when it has not been employed.

What component or system failed or malfunctioned, and is it available for inspection upon request? I was driving and the car completely shut down- I could not use my brakes or accelerate. I had to pull along the road in ongoing traffic to coast to a stop. I lost all control. How was your safety or the safety of others put at risk? I was in traffic and the cars behind me had to slow down immediately, I could not speed up or even brake to come to a stop. Others around me as well as myself were in danger. Has the problem been reproduced or confirmed by a dealer or independent service center? They reviewed and said they scanned it and did a drive test and could not find the cause. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, It was seen at the Kia dealer I bought it from. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? As soon as the vehicle lost power there was a warning sign on the dash that showed "limit" with a half circle emblem.

CURRENT MILEAGE 6,776 miles -Purchased the vehicle and on two occasions the AEB Emergency brake system came on twice without any cars around- Also, twice the engine shutdown light came on and acceleration has stopped on me and the vehicle stalled, which is dangerous if Im on the parkway or road where I cant pull over like a bridge. NICE LOOKING CAR BUT DONT BE FOOLED- A RECALL NEEDS TO BE SENT TO PROTECT OTHERS FROM A CRASH IMMEDIATELY.

On 3 different occasion when parking in my driveway (on a hill) my car rolled while in park. On the first occasion I almost ran over my wife who was taking our young daughter out of her car seat. Fortunately I was still in the drivers seat and able to press my foot on the brake. On the next two occasions there was nobody around and the car rolled into the street. I have contacted Kia repeatedly to fix this issue and they have done nothing. The dealership says there is nothing wrong and is now refusing to answer calls from myself and Kia. Kia is saying it's up to the dealership to fix. This is incredibly dangerous for people who are not aware there is an issue. The dealer accused me of not activating the parking brake. As I explained to them the car would have rolled me over before I could walk away - so that is impossible. I can't replicate this every time. I have been able to replicate it one other time but did not get it on video. This makes the situation that much more dangerous especially with little kids. I now park every time with my emergency brake engaged.

On [XXX] while driving and in the process of changing lanes, as I accelerated on the brakes, my Vehicle gave a sudden jerk, at first I figured it was due to the road being wet, but on [XXX] while driving to NYC on [XXX] as we all know we all have to keep up the speed, once again during accelerating my vehicle repeated the same sudden jerk and continue for most of my ride, I brought into KIA on [XXX] with the end result being they did not find this issue, as well as my ongoing issue of my engine light that has been coming on and off for about 5 months now. I do believe my vehicle is having some kind of issue with the transmission and gears are not kicking in during the acceleration process may I add this is on the highway. My vehicle is a 2023 which I purchased in Aug of 2023 and have been in the dealership for shaking during braking engine light on and now gear delay with no resolution to all issues, I will be contacting the Manufactured as my next step in the horrible processes.

The contact owns a 2023 Kia Sorento. The contact stated that while driving at an undisclosed speed, the brakes spontaneously engaged. The brake warning light was illuminated. The contact stated there was no other vehicles nearby when the failure occurred on several occasions. Additionally, the sunroof was deactivated due to the software being disconnected spontaneously. The vehicle was taken to the dealer; however, the dealer was unable to duplicate the failure and informed the contact that the manufacturer needed to be contacted to check the logs. The manufacturer was made aware of the failure. The failure mileage was approximately 35,000.
