2022 KIA Sorento Phev problems

ELECTRICAL SYSTEM

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.

POWER TRAIN

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!!!

POWER TRAIN

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.

SERVICE BRAKES

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.

ELECTRICAL SYSTEM

My 2022 KIA Sorrento PHEV periodically gives a "Check Hybrid System, Stop Safely" emergency warning. When this happens the vehicle will not accelerate and can only be limped to a stop. This has occurred 4 times in 18 months. In three instances the vehicle was limped to a safe stop but on the other occasion it left us stranded in an intersection. This problem creates imminent danger and potential peril. KIA maintenance looked at the vehicle after the last two events and reported that they can't do anything because there aren't any recorded fault codes. From a technical perspective, it appears that an electronic problem occurs where the hybrid control either fails to recognize the low battery status or fails to command the engine to run when needed. Once stopped I can see that the hybrid electric battery charge has depleted and the engine failed to start. Cycling power off and on a couple of times appears to reset the circuitry allowing the engine to restart and the hybrid battery to begin recharging. Unfortunately, the KIA OBD is not detecting this particular failure.

Multiple times I have experienced weirdness with the Transmission in my 2022 Sorento PHEV. One specific situation has happened to me multiple times and is a safety risk. Occasionally while stopped at a red light or stop sign with a reasonable incline it seems the electric motor fails to engage and it never switches to the ICE engine either. Step by step 1 - Stopped at Stop Sign or Red light 2- Release Brake an Hit Gas 3- Vehicle does not move forward no matter how hard you hit the gas (Doesnt seem to engage electric or traditional engine) 4 - Instead the vehicle seems like its in neutral and starts rolling backwards 5 - I slam on the brakes, and then try the gas again and everything is fine. I took it to the Anderson, SC kia dealer and they just told me they couldn't replicate it. It has happened to me or my wife probably 4 times over the last year. Just wanted to report it because it feels like a good chance this is eventually going to cause a wreck.
