NHTSA Complaint #11560570 — 2022 KIA SORENTO PHEV

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.
