On 9/3/2019 I took my 2012 Kia Optima to gossett Kia South to get it repaired. It didnt get fixed before I left the lot my car was smoking and leaking antifreeze. I was stranded for 4 days after that day. I went to the nearest part store and purchased a bottom radiator hose and antifreeze. I had a mobile mechanic to put the hose on. There after I was stranded again the car wouldn't start. I had it towed to Firestone 10/4/2019. My car stayed the lot for a month and it was then towed to gossett Kia North from there it has been repossessed. I made payment arrangements to get the car back I am determined to get my car repaired. I use the car to make it to appointments. I am disabled and this doesnt seem fair at all im paying notes on a nonworking car. I hope to hear from you soon with further advice

I was traveling down E 470 in Colorado with my grandchildren when my car suddenly ceased up and blew a rod going 70 mph. A car almost hit me from behind and luckily I was able to get over so I didn't cause any more damage to me my family or anyone else. My car had oil and had been change just recently. I am seeing that this is a problem with these cars. Just wanted to report that this has happened to me also.

Kia has now settled their class action suit for all the other vehicles, yet the hybrids are still being left out of any recalls. There is plenty of evidence in the complaints here that something is wrong. I sunk $7000 that I didn't have to spare into getting a new engine put in this car. Only to have the transmission blow right after I got the car back from Kia after waiting 6 months for an engine. The transmission cost another $5000, and it took them three transmissions to install a non-faulty transmission. I almost lost my job because I couldn't reliably get to work on time, if at all. Kia themselves have said that the engines weren't manufactured correctly and that labor being done in Kia dealerships wasn't being done correctly. Hybrid engines should absolutely not be blowing rods at 60000 miles, or 80000 miles, and not even 100000 miles. Kia is knowingly delaying any sort of recall and forcing people to go into further debt or lose jobs.

Failure date: 06/25/2019 my 2012 Kia Optima engine shut off while I was driving and luckily I didnt get into accident and was able pull off the road to wait for a tow truck. This is very scary and dangerous. I had it towed to an auto repair garage they changed out the started and changed out the battery it just made a clicking sound but wouldn't start. I started reading on line that this exact situation has happened to other Kia Optima vehicles. My vehicle has 99189 miles so it falls within the power train warranty of 100,000 miles

During my last visit to the Kia dealer for an oil change and tire rotation, they informed my that I had no oil indicating on the dip stick. No leaks detected so must be burning oil. Every time I drive, I can smell burning oil and tail pipe are completely black.

2012 Kia was taken in for a engine recall in 2017. Kia informed me that it had passed inspection and released the car. 2019 the engine seized without warning, traveling 40mph on a busy road. Luckily, I was able to maneuver to find a somewhat safe location. My engine began to smoke very badly from a possible small fire. After a week without a car, out of pocket tows, diagnostics, rentals, etc. Kia confirmed it was an engine issue related to the recall. My safety was placed at risk after I felt all the recalls had been taken care of. I could of very well been in a serious accident, and luckily I did not have my children that day. Today, my car has had a replacement engine, yet I do not feel comfortable. I am still trying to recover the out of pocket expenses. I have been spoken to very rudely and in a unprofessional manner from Kia. The company is not willing to pay for all of my expenses while the car that I have purchased from them put me in harms way. I will never buy another Kia again and am considering a law suit.

There are two (2) issues that are possibly connected. The first is excessive oil consumption. The Kia dealership confirms that I am using approximately 1 quart per 250 miles, but they state that they cannot do anything for the issue. Additionally, the car has also become sluggish. Acceleration time has been greatly increased and car hesitates when the gas pedal is depressed. Both of these issues have me concerned for my safety in normal driving conditions and also when I need to accelerate quickly.

Car being driven by my daughter suddenly stopped in the middle of traffic with a pull over and safely shut off vehicle warning. She however could not move. The vehicle also showed an error to the vehicle charging system. We towed the immobile vehicle to the local Kia dealership and were told there were no codes and the battery was fine. They requested that I allow them to remove the valve cover to check on belts. I approved. I called the dealership the following day to check in because I have not heard. I was told the hybrid parts were covered under warranty but that the engine was locked up. No reason or explanation, no warning. My child could have died due to her vehicle stopping in the middle of traffic.

I have had multiple issues with my 2012 Kia Optima hybrid for the past 3-4 years. The transmission has been replaced at 74K mi. Numerous occasions car lost power on the highway. Taken car in to Kia dealer each time and they could not duplicate the problem. My car stalled out 1 month ago on the freeway and towed to the dealer. Now at 125K mi dealer is telling me my engine is seized, hybrid battery and regular battery are dead. And also replaced the emc for $2500 prior to figuring out the engine/battery's were dead.

Until now (only 84K miles), my 2012 Kia Optima hybrid has been a great car. When leaving a driveway going about 15mph, a light tapping began when the gas engine started. A sound it was not making when driving under electric power (before the engine started). The sound quickly grew to a loud knocking, accompanied by a noticeable loss of power and throttle response. The check engine light never turned on, even after the engine blew up. All signs are pointing to a manufacturing defect, similar, if not the same as the one regarding metal filings being left on the block. This is the same engine model and year that triggered over.5M cars being recalled. Now the same issues are happening with this model, which for some reason wasn't included. A modern and well-serviced car should last more than 84K miles. This will be a safety hazard until all models containing these engines are repaired.

I have a 2012 Kia Optima hybrid at 80, xxx, and have always kept up with the scheduled services/maintenance. I barely drive my car nowadays, and just ride my bicycle to take public transportation that is 1-mile away. My wife and I were driving on the freeway, going 65mph, 47-miles into our drive, our car started jerking. We have about 3-4 miles left to our destination. When you pressed on the gas, it sounded like it was just accelerating and not shifting to the next gear. There were no warning lights or notification as to why that was happening. We exited from the freeway and stopped at a local plaza to try and reset the car, and gave the car about 20-mins before driving again. When we tried driving about the last 10-mins, even at 20mph, it was still jerking and still sounded like it wasn't shifting to the next gear, and still no warning lights. We ended up towing our car back home because we didn't want to risk getting stuck on the freeway at 1-2am. Unfortunately, I am the 2nd owner, however, I do have extended warranty, so I hope this issue is not that serious. I will definitely contact Kia and raise this concern because it is a safety hazard.

My 2012 Kia Optima on multiple occasions has shut off while the vehicle was in motion. While driving, as I decrease my speed, suddenly the car will experience jerking and then suddenly shut off. This has occur while driving on the freeway and traffic has slowed down to 10 mph or less and while approaching a light or crossing and intersection and traffic is slowing down. While the car is at steady speed, at 20 - 40 mph the car jerks as I'm trying to maintain with the flow of traffic. My car has had routine maintenance and mechanics have been unable to identify or remedy the issue. My last two incidents were 8/21/19 freeway while in the fast lane next to the carpool lane and now 8/29 on city street. I also experienced this on March 3,2019 (had a fuel pump replacement which still did not remedy the issue)
