2013 Kia Optima Hybrid Other or unknown Problems

“The mpg has decreased from 38-40 mpg to 30 mpg since I had the fuel injection service performed. The dealer offers no help. Wish I never had it done.....I get sudden surges of acceleration while driving on the highway. I've had to apply the brakes to slow down. Since this is an intermittent problem the dealer states they cannot help me. The newest issue is when turning the temperature down in the car to low it kicks on the AC. This too is an intermittent problem. …”

“While I was driving my 2013 Kia Optima Hybrid this morning. While driving, I suddenly got a warning message that said hybrid system failure stop safely do not drive . I pulled over and smelled what seemed to be fire, but saw nothing. I called my fianc to let him know what was going on and the cabin started filling with smoke. I jumped out of the car and popped the trunk. There were flames shooting out of the hybrid system. The fire was extinguished, the car is now sitting in a tow yard. I take very good care of my car. There is nothing that I would have done or could have done to cause this.”

“Shortly after purchase took a trip to texas to see my daughter. On three separate occasions on that trip; was going down the interstate with the cruise control set, all of the sudden it started accelerating all on it's own... The 1st time I questioned if I had accidently bumped something, the 2nd also and the 3rd allowed it to act on its own and before I knew it was almost 100mph. Thankfully the brake engages.. When I returned home I immediately took it in for check and was told they could not recreate the problem so nothing could be done.. …”

“From a stop at a light or intersection, over seven (7) times the car has jolted forward and stopped abruptly, losing most power to the motor at that point. Audible alarms ring and the dashboard has read both hybrid system warning! Immediately stop and do not drive and check charging system . This has happened during left turns with oncoming traffic that then has to slow as I slowly creep out of the intersection.”

“Vehicle surged forward while in motion to park in a parking space. Brakes failed to stop vehicle from a very slow speed of 5-10 MPH approximately. Has done this on occasion at highway speed a sudden surge so a braking would relieve problem.”
