My active air flapp system is defaulting and transmission going out. Not to mention the hesitation when accelerating

- Owensboro, KY, USA

My 2011 Kia Optima hybrid had an engine failure, car kept stalling so bought a 300 dollar battery. Well the car stalled again while driving, took it to the Kia service center just to tell me the engine was blown. There's been several consumer complaints about engine failure on these vehicles so whats taking long to recall these engine mishaps. Called customer care and was informed with no help whatsoever. Several consumers have come out of pocket for these neglected engine failures and nothing is being done.

Took my car to the dealer in camp springs, Maryland to have an analysis done and to install a new air bag recall from dmv. One of the issues was to check my fluids and to see why my car hesitates and makes a clanking noise after driving a period of time. Now, it didn't happen all the time. Just when it was driven for a few hours straight. One of the dealers service rep reported that the engine was burning oil. After reading the report, I would constantly check the oil. When I first notice the clacking noise, I would check the oil. There was plenty of oil in the car, however, my coolant container was low. Purchased coolant for the vehicle. A month later, the container was almost empty again. Apparently, the coolant was leaking into the engine. Now I have an engine problem.

- Upper Marlboro, MD, USA

ECU malfunction causing misfire in cylinder one resulting in ignition coil melting and and causing electrical fire in engine bay while in motion on local street. Vehicle is now inoperable.

- Palisades Park, NJ, USA

Our car began exhibiting a clacking noise when driving that would worsen with acceleration. Within 1-2 drives, it quickly progressed to be quite loud and constant, so we took it to our local dealership. We were informed that our engine had thrown a rod and would need to be completely replaced. We are just outside the 100,000 mile warranty and bought the car brand new in 2012 (yes, the year after the model date, taking advantage of the price break in buying old stock), so it is still a fairly young engine to be having this problem. It appears other non-hybrid Kia and Hyundai models from the same year are having the same problem and have been recalled, but nothing on the hybrid vehicles, despite that we were also told this has been a common problem.

- Port Deposit, MD, USA

Engine misfire in cylinder # 1. the engine began to smoke, check engine (P0301) illuminated. Ignition coil was melted now car does not start. Engine failure. This happened on a short trip to the store limped the car back home. Kia refuses to recall this optima engine because its a hybrid although it has failed and has been recalled on multiple same year Kia optimas due to metal deposits in the engine from factory.

- Palisades Park, NJ, USA

The engine has experienced what other Kia engines have. Engine oil was either blocked or rapidly burnt up, causing the engine to spin a rod bearing, thus needing a new engine. Luckily I stopped driving immediately, preventing a fire; as has happened in other Kia vehicles. Sadly, Kia is refusing to warranty or recall the hybrid engines, even though many are experiencing the same issues.

- Laveen, AZ, USA

While driving, the engine began making a loud cyclical knocking sound. We had it towed to the local Kia dealer whose reported diagnosis was "characteristic of rod bearing failure" and we were informed that the only remedy was to have the engine replaced. Informed by local dealer that Kia had declined the claim to have it replaced and that the only course of action was to take it up with Kia Consumer Affairs. After multiple conversations with Kia Consumer Affairs (including a 2 week time lapse during which they would take out calls but not notify us of decisions made unless we called them), we were finally informed that even though all other 2011 Kia optimas had been recalled up to 125,000 miles, for "rod bearing failure" and thus had their engines replaced, our 2011 Kia optima was not covered for rod bearing failure because it was a hybrid. They would not assist in any way with replacing the engine even though this is a well documented issue with Kia optimas. The local dealer offered a used engine for the whopping price of $5474.17 with no warranty or to rebuild the engine with parts they would have to order from Korea for a whopping total of $5710.75. The latter option would include a 12,000 mile warranty but would require a lengthy wait on the parts to arrive from Korea. Evidently, Kia does not keep needed parts in the entire United States which sounds sketchy at best. After much deliberation and agony, we will sell the car for scraps. We cannot risk spending almost $6000 on a car and cooperation that we now have very little faith in. We will never own a Kia again.

- Wilson, NC, USA

The contact owns a 2011 Kia Optima hybrid. The contact stated that the engine seized while driving 60 mph. The contact was able to coast the vehicle over to the emergency lane. There were no warning indicators illuminated. The contact was able to drive the vehicle. The contact also stated that the vehicle made a very loud knocking noise and sounded like something was dragging from the bottom of the vehicle. The contact coasted to the side of the road and was unable to restart the vehicle. The vehicle was towed to an unknown Kia dealer in irvine, ca. The contact was informed that the engine needed to be torn down to determine what caused the failure. The technician diagnosed that the failure was due to a rod bearing and there were metal shavings in the oil pan; however, the vehicle was free of sludge. The manufacturer was contacted. Because the contact was the third owner of the vehicle, the vehicle would not be repaired for free. The contact was also informed that the failure was identical to a previous unknown recall. The vehicle had a 100,000 mile warranty, which was no longer valid. The approximate failure mileage was 67,000. The VIN was not available.

My engine did exactly as the recall on the non-hybrid engines. Lost oil pressure, oil indicator came on, check engine light came on as engine seized on highway during driving. Dealership refusing to include my car engine in recall because of hybrid -even though it has a gas engine. Kia corporate contacted and stated they were willing to "work something out" with it if dealership will contact them. I cannot get dealership to do this yet. Likely legal counsel will have to be contacted. Insurance adjuster also commented defective part likely cause. Good thing I did no have cardiac issue -had to wait in heat on highway during summer morning for tow truck after sudden engine failure in traffic while exiting on to the highway. Also fortunate the cars behind me did not hit me causing more damage or personal injury. Still traumatic experience.

- Tulsa, OK, USA

While accelerating from a dead stop, the car hesitated and stopped until it appeared to shift from electric to gas power. I thought at the time that it may have been a freak thing but this hesitation has recurred a few times since then.

When applying gas pedal to pull away from a dead stop--such as a stop sign or red light---car stumbles and hesitates. At times car will not even respond when gas pedal is pushed. Push the gas pedal and nothing happens--then you push pedal a bit more and it jerks and shoots forward. Not a comfortable situation when trying to pull into traffic from a intersection. Happens virtually every time. Cold or warmed up--same problem--except a lot worse at cold start. Once above 30 mpg things smooth out--but the big danger is trying to pull out into traffic. I have been to the dealer several times. They do a re-flash or whatever--then tell me it drives normal. No fault with the dealer at all--they have been excellent really--but--can't fix the hesitation.but driving normal--that's not true. They know they have a problem with this hybrid system--there is a web page that addresses this problem---everyone has the same problem. I can't even allow a friend or one of my kids drive this car.if you don't know how the cars going to react---your open to a serious accident. I have had a Camry hybrid and two prius hybrids--no problems. I know how a hybrid car should drive. This car is unsafe for the driver and other mortorists on the road.
