2022 KIA SORENTO PHEV Complaints

On XXX, during a 13 hour return trip from [XXX], while traveling at speeds of approximately 80 mph on the interstate in mountainous terrain with my family in the vehicle, the instrument cluster displayed a message instructing me to stop driving and take the vehicle to service due to a battery problem. After the message cleared, a warning light remained illuminated until the vehicle was shut off and restarted. This occurred three separate times during that trip, beginning approximately five hours from home. I attempted to reach a Kia dealership in [XXX], and was unable to get anyone on the phone. Having no alternative, I continued driving home. On XXX, during a two and a half hour highway drive on flat terrain, the vehicle displayed "Battery system hot: switching to HEV mode." Separately, and for several months, charging at home on a Level 1 charger repeatedly stops approximately ten minutes into the session. A check engine light appears and clears after two restarts. The vehicle was at an authorized Kia dealership from XXX, for fifteen days. Their scan at 90,776 miles found diagnostic trouble code P1B9700, High Voltage Battery Temperature Deviation, stored in the Battery Management System with freeze frame data captured. The dealership drove the vehicle 387 miles, primarily in EV mode in 40 mile increments, and returned it with the notation "no repairs attempted at this time, unable to duplicate concern at this time." No Kia Techline case was opened and no field technical specialist was involved. The freeze frame data has not been provided to me despite written requests. The dealership described its procedure as clearing the history code before attempting to duplicate the concern. No repair has been performed. The vehicle remains in daily use by my wife. Kia Consumer Affairs case 26352951 is open. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine wiring is covered in soy based products which attract rodents as a source of food. Rodents then chew various wires and damage the electrical system. The check engine light has popped on twice in one year with both times requiring service repair for the chewed wires. There is a potential for electrical fires or other various failures due to rodents chewing through the wires. Kia has known about this problem for over a decade and continues to use soy based coverings in their engine without any mitigation for rodents.

The drive train and motor slow to a near stop in traffic when trying to clear a lane and makes it very dangerouos for other traffic to have to wait for me to clear a lane. There is something wrong and we complained about this before the warranty ran out, but they could not find anything. The car stops in traffic unexpectedly. I am not sure if sensors are causing this or what, but it has put me in danger of collision many times. We have to plan an exceedingly long time to pull into traffic so we don't get run over. Anti slip also doesn't turn off even though it says it is off. The car will slip a little bit and then shut the motor down to a crawl making it very dangerous in traffic. The 4x4 doesn't seem to work as we turn it on to try to eleminate slipping. The slipping mostly occurs because of the motor becoming doggedly slow and then decides to speed up. The 4x4 on and the turning of the anti-slip do not work because it still slips and shuts down. The other tires don't seem to slip or do anything. Please help!!!

My Sorento PHEV popped a P0c4e code and now the car is gutless on electric power. Kia cleared the code in an attempt to fix it but now the code is gone and it’s still weak. When I let off the brake it rolls when it used to have the power to hold it. I used to be able to get on the freeway and now I can’t get up to speed in town (35mph). It’s running in some sort of limp mode and Kia can’t see any codes. It’s loud, too. Each gear whines. It whines when I hit the brake and it regenerates electricity. It regens so little now that it doesn’t hardly slow me down anymore until I stand on them and use the brake pads. Kia said that it might be a sensor in the electric motor but it’s not replaceable and you have to replace the whole motor. Even though it’s under warranty, it’s 15 hours labor to replace it. I have family with the same car and theirs has done the same thing in the past and had to be replaced. My dealer said that they have seen a bunch of these throw that same code and have to have the motor replaced. She said she is expecting Kia to start replacing them for free or possibly recall them because of how many she has seen all doing the same thing.

I have gotten the notice Refill Inverter Coolant and Hybrid System Failure and lost acceleration and the all power. The first time this happened was in Dec 2024 with about 60,000 miles on the car. Dealer flushed system and it worked fine until April 2025 at about 71000 miles Hybrid system failure alert again, barely able to accelerate from stop light, made to a parking space just as I lost power steering. After about 2 hours to cool off car started and could be driven home. Got Refill inverter coolant alert.

The contact owns a 2022 Kia Sorento PHEV. The contact stated that while reversing the vehicle, the rearview camera failed to display a clear image, and the grid lines were not properly aligned. The contact crashed the vehicle into his mailbox. There were no injuries sustained and no police report was filed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA Campaign Number: 23V610000 (Back Over Prevention); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 22,500.

Several times over the past 12 months, the car has applied emergency braking when a car approaches me from behind in the lane to my left. The dealer was not able to replicate the problem but I have captured it twice on my dash cam. I was only able to intentionally replicate the problem once on my own but it has happened 15-20 times. If I do not press the accelerator, the car will come to a stop without me pushing the brake. When the emergency brake is applied, the warning sound is heard in the car and the dash lights up with the emergency braking icon and emphasizes the left rear of the vehicle. I have been to the dealer twice for this issue. The first time they told me it was due to a faulty camera mount under recall. It was replaced but the issue continued. The second time they told me they decreased the sensitivity of some sensor. The issue continued.

While driving down the highway the EV side of my PHEV wouldn't switch to gas. The car wouldn't accelerate past 40-50 mph and drained the remaining battery till my car shut off and forced me to the side of the road. Been to the dealer multiple times (over 4) for the same issue. They claim they recreate it and no resolution has been done.

The contact owns a 2022 Kia Sorento PHEV. The contact stated the upon starting the vehicle, an abnormally loud revving sound was coming from the engine while the vehicle was idling. Additionally, the contact stated that the vehicle hesitated upon the depression of the accelerator pedal while traveling at various speeds. No warning light was illuminated. The vehicle was initially taken to Seelye Kia of Battle Creek (791 W Dickman Rd, Battle Creek, MI 49037) where the contact was informed that the acceleration issue was normal vehicle operation due to the Hybrid feature. The vehicle was then taken to another dealer where the contact was provided the same issue as the dealer. The contact stated that the hesitation had worsened and had become more frequent. The manufacturer was notified of the failure and the contact was provided a case number. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 20,000.
