When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2021 KIA Sorento Hybrid

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Pedestrian alert sounds

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States.

Recalls on the 2021 KIA Sorento Hybrid

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

ELECTRICAL SYSTEM

On [XXX] we were driving the Kia at slow speed due to snow on the road when a warning light came on which we think said hybrid vehicle failure pull over. The car stopped and the traffic lane with the engine off. The car would not start and we were exposed to traffic. Fortunately, we were on a country road at the time about a mile from our house and we were not struck by following vehicle when the car shut off and stopped in the traffic lane. If we had been on a beltway with 60 or 65 mph traffic obviously the result would’ve been quite different. Because I felt the vehicle was not safe to drive. I had it towed to the Kia dealer in Salisbury Pocahontas Kia, who have not been able to duplicate the problem and have also not been able to tell us what was wrong with the Kia to cause this problem in the first place. Unless there is a clear reason why this happened And it can be fixed then we have no reason to believe this would not happen again and endanger our safety.

For a few days ( especially if is a HOT day (over 80F) ) my 2021 Kia Sorento Hybrid with 15,421 miles on it displays a "Refill Inverter Coolant" message. I checked the coolant level and is OK. After my research, it seems that the factory put the wrong Blue inverter coolant instead Red (all other KIA hybrid cars have Red coolant) . I found out that there is a KIA Technical Service Bulletin SA515 that addresses this issue. Called a few dealers in GA and I have been told that they need the cars for 7-10 days for investigation. Why???? when there is a Service Bulletin.. On top of this, I have been told that I need to rent a car at my expense and fight with KIA Corp to be reimbursed. This is Outrageous!!!!!! Other dealers do not have the required Vaccum Pump to flush the system or they can schedule me after 25 days. A safety Recall shall be issued and put pressure on KIA to address this issues before a catastrophic inverter fault occurs

UNKNOWN OR OTHER

My Kia Sorento will shift from drive to first or second gear’s several times. I’ve been told by the dealership that I’m probably touching the shifter accidentally, I disagree. My opinion is that this is a safety concern because it slows the vehicle down. My vehicle also at times does not accelerate. These two issues are intermittent.

Cypress, CA

UNKNOWN OR OTHER

UNKNOWN. The “Replace Inverter Coolant” warning message repeatedly comes on for unknown reasons and may be quickly reset to the “Ready to Drive” status by turning the vehicle off, opening the driver side door, putting my foot on the break pedal, turning the vehicle back on and closing the door before the system readiness cycle is completed. While this is not perhaps an injury issue to anyone, it is a nuisance issue which KIA apparently refuses to issue a recall to fix. The reliability of the Inverter Coolant monitoring system is important to the driving public of KIA vehicles and a system that is unreliable should not be tolerated. This issue is also known to exist on numerous other KIA manufactured and marketed models.

i have 2021 Kia Sorento Hybrid, which a regular message stating that it needs to refill inverter coolant fluid keeps coming up, even though the car coolants level is full. This is not a new problem for the all the Kia users that have this model. Also, Kia and their network of dealerships have known of this problem for over 1 yr and their standard answer is" we know its a software program, and will get back to you once the software code is fixed". Basically, they are dismissing the complaints and issues from the car owners. Also, this is poses a security and safety concern, since the warning light/message takes over the entire center console/display. Other relevant safety and security warnings/functionality is obstructed by it. Please force Kia to make this a mandatory recall for all Hybrid owners. There are thousands of customers impacted.

Refil inverter fluid warning light is on constant, this doesn’t allow the driver to access any digital information while vehicle is on. The vehicle is also having issues with the entertainment consul, Bluetooth connection issues along with the ability to access apple car play. Dealership says it’s Kia and nothing is being done. Various forums with others having similar issues.

Vehicle has a constant, unresolved error reporting that Inverter Coolant level is abnormal. Occurs daily. Dealership is unable to determine whether it is an issue. Has been taken to the dealership 2 times in the last 3 months. The warning also occupies the dashboard screen and cannot be dismissed, preventing me from viewing any vehicle details (engine temperature, tire pressure, digital speedometer)

Inverter fluid light has been coming on and staying on for over a month. It impedes the view of the digital display. The dealership has no fix nor any rental vehicles to bring my vehicle in. I have had this vehicle for 14 months. No one can tell me if this consistent light is harming my vehicle nor is there an urgency to repair. Unacceptable in a 40 grand vehicle

ELECTRICAL SYSTEM

There is a warning message stating "Refill Invertor Coolant" that keeps coming up. The coolant is already full and the car functions normally. However, the warning message can only be cleared for a few seconds before it returns. The message covers up other information on the display such as digital speed and driving warnings such as lane departure. I feel this is an unsafe condition. The dealer I talked to said they are aware of the issue and trying to resolve it on another customer's car. At this time they are unable to resolve the issue.

The inverter coolant refill light will illuminate at all times even with the system serviced. Kia has serviced the system but has no solution on how to stop the light. The light also blocks out any other warning that may happen on the dash. With the light illuminated while driving, it is impossible to determine if the system is empty to cause a fire or just a faulty light. The dealership has confirmed the faulty warning light. There are no computer codes associated with the warning light.
