I believe the Hybrid Propulsion System in my kia optima hybrid should have been part of the recall. The vehicle is currently showing signs of the vehicle's Voltage Protection Device activating inadvertently, causing a sudden loss of power. Vehicle is currently with an authorized dealership being tested.

The Hybrid Warning light came on. This was the third time this has happened. The first time Kia said it was the Air Box and I paid $600 to repair. The second time the shop mistakenly cleared the codes before determining the cause. The third time they say it is the Wiring Harness and will cost $4,550 to report if they have the harness. This vehicle has recall for the connecting rod in the engine which I suspect is the real issue due to clicking noise it makes just before the lights come on, but each time I take it in I am told it is something else. Since it is the Wiring Harness this time it could be a fire hazard especiall on a Hybrid with Lithium batteries, I am not going to repair it as…
