NHTSA Complaint #11433935 — 2012 KIA OPTIMA

My wife had been complaining that while driving 2011 optima hybrid at highway speeds the car would suddenly lose power and slow to 30 or 40 mph while the pedal is floored. Took it to the dealer who said we needed a new battery which did not solve the problem. 2nd time came with a warning on the dash to check hybrid system, back at the dealer they said it appears to be some special fuse in the trunk ($300)…problem sill persist however this time the car completely shut down on the road, dash was lit up like a Christmas tree. Had to get it towed. Now dealer says its the HPCU and that’s going to run almost $6000. Dealer was willing to install a used one i got on EBay, they charged $1300 for the install they tell me the problem still exists.
