NHTSA Complaint #11454853 — 2015 KIA OPTIMA

I was driving my 2015 Kia Optima hybrid with around 77,000 miles on the interstate at 70 mph when the HCS, battery management system and other hybrid battery warnings flashed on the screen. The display said to pullover over immediately and turn off the engine. The hybrid battery charge display went from mid charge to zero charge. The car went into limp mode with very limited power. Fortunately, I was able to get off the highway as there was an exit ramp close by. After turning off the car, it would not start again. I disconnected the 12V battery hoping it would clear it out but that didn't work. Had to get car towed to the Kia dealership. They replaced the hybrid battery's high voltage 125 Amp fuse with a 150 Amp fuse and the problem was fixed (cost of $370). A search on the internet revealed that this is a common occurrence on 2011 to 2016 Kia hybrids and Kia knows about this faulty/inadequate fuse problem but refuses to issue a recall. Kia issued a TSB #PS-515 DTC P1B25/P1B77 – 125 AMP HV FUSE INSPECTION that states to inspect the resistance on the factory 125 A fuse and replace if less than 1 Ohm resistance with new 150 A fuse. This is a relatively simple fix for Kia that could prevent a dangerous situation if the car were to lose power on a crowded interstate.
