2010 Kia Optima Engine Problems

“My Optima has 104,000 miles. Just last week while driving on wet roads, I lost control as the power steering stopped working. The battery light comes on during this period for between 5-30 seconds as you loose almost all control of your vehicle's steering. Just as your vehicle gains power steering again, a screeching sounds comes from the engine compartment (maybe belts re-engaging). It has been raining her the past week and the issue has happened about 8 times. Sometimes directly after driving through puddles, and sometimes just while driving. …”

“While driving home one day in december 2015, each time I approached a stop light, yield sign or slowed to a low speed (less than 15 MPH), my vehicle would shut-off multiple times. My in motion speed was approx 45 MPH when not approaching a stop light or yield sign. It happened both when I was turning and going straight on main roads with 2-4 lanes. The dealership and another asme certified mechanic both state engine failure, which seems to be a widespread problem with 2.4l engines manufactured by Kia and hyundai around this year up to 2015.”

“Engine blew doing 40-45 on a county road 1,000 RPM 5th gear, in automatic. 2nd to 1st, soft to hard kick. Vehicle speed sensor must be faulty I have to pump brake more to slow the engine speed it likes to bog trying to speed up in automatic mode”

“Driving car just shut off in heavy traffic on rd average speed 40 no warning lights came on restarted stalled all the way home and huge knocking sound”

“The engine on my 2010 Kia Optima suddenly seized without warning around 150,000 miles. The vehicle had no knocking sounds or warning signs prior to failure. A mechanic diagnosed the vehicle with a seized engine. This created a sudden loss of vehicle operation. I am concerned this may be related to the known engine failure issues reported in Kia vehicles.”
