Recall SA512 was previously completed on my vehicle. The problem is happening again. Since there are no open recalls, I am unable to get it fixed under the recall.

Filed Jan 21, 2025 · Electrical, Engine · MD

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.

There is a malfunction in the vehicles.computer system that gives a warning about low coolant level for the hybrid battery. It's been been seen by the KIA dealer and the issue keeps arriving.

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

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.

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.

My Kia 2021 Hybrid EX has a message warning to "refill inverter coolant". Took it to dealer and they said it's a software issue, but no remedy is available.

Filed Sep 2, 2022 · Engine · CA

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.
