My engine failed. Dick Withams here in Waterloo, IA was paid by Kia to replace engine for free due to my warranty. Dick Withams rushed the process and allowed me back on the road with no coolant plug( which was detected immediately) I returned the car and Dick Withams attached a plug so my coolant wouldn't spill over on the ground. Every time I pressed my brakes THERE WAS A HORRIBLE SOUND LIKE MY DRIVE AXIAL WAS NOT PUT TOGETHER WHEN Putting the engine back. Kia is allowing Mechanics to fix these recalls of MAJOR SAFETY ISSUES FOR myself and my family. I then returned vehicle to Cedar Falls, IA Dick Withams to fix issue Friday morning. They have yet to communicate anything with me. Now I'm just without a vehicle even though it's covered under warranty. It should be against the law for the car dealership to return a recalled engine without driving the car to see if they rushed the service and failed to put vehicle back together CORRECTLY.

I was driving on the highway and suddenly lost acceleration, the check engine light began flashing. The car went into limp mode. I got it to an auto parts store and had them put it on the scanner. It is showing code P1326. I have it scheduled to be assessed at Kia. Research on this code with the Kia says, it could need a system update, knock sensor replaced, or the engine replaced. Kia does have a recall out for this issue but my car doesn-??t currently fall under the recall. My car has always been mechanically maintained at appropriate intervals by Kia. This is a problem.

My car lost power going 70mph and the engine light came on. I had it scanned and the code was P1326. Now my car will not move. This was a reported recall on Kia Optima from years 2011-2014. My car is a 2012 Kia Optima. I called dealership and they said my VIN is not under this recall but I am having the same exact problem as the recall reported in 2018.

Driving at 60 mph on the highway engine seized up with no warning what so ever no engine light or oil light. Once vehicle stopped checked oil and it was almost empty. No warning of oil pressure or oil low. Vehicle always inspected an oil change done on time. Can't find recall on my vin but other 2012 models had a recall for this exact reason. I was almost hit by a semi when the vehicle just died with no warning at all and everything locked up. Never had 1 issue with this vehicle until now. And I am worried kia will not fix it when clearly other optimas of the same year had the same issue. I can't understand why when vin search it doesn't show this recall. It's all over the internet.

Oil changed every 3000 miles. Driving to work the other day check engine light came on. Car went into limp mode. Pulled code and it was for rod bearings. Supposedly rod bearings had been repaired by recall before. Car only has 91,000 miles on it. So shouldn't need another set of rod bearings if previously replaced.
