What owners say

The contact owns a 2011 Kia Optima. The contact stated that while a family member was driving and exiting a parking lot, the vehicle turned off, causing the vehicle to lose power. The contact stated that there was a burning odor inside the cabin of the vehicle with an audible clicking sound coming from the starter motor. The vehicle was towed to a local authorized dealer. The contact referenced the federal safety agency Campaign Number: 17V224000 (Engine and Engine Cooling) and Kia Warranty Bulletin 2017-09.R4 as the possible causes for the failure. The manufacturer was notified of the failure but refused to accept or authorize the recall repair because the vehicle had a salvage title. The authorized dealer also declined to service the vehicle due to the salvage title. The failure mileage was 77,500.

The vehicle's engine had previously been replaced once under Kia's Theta II engine recall/warranty program approximately five years prior to this incident. On the date of failure, the replacement engine catastrophically failed while the vehicle was in operation, resulting in the engine developing a hole in the engine block and becoming inoperable. Prior to the failure, the vehicle exhibited a "check engine" warning and symptoms consistent with connecting rod bearing failure. Diagnostic trouble codes P1326 and P0303 were present upon inspection at an authorized Kia dealership. The failure occurred at approximately 198,000 miles. This is the second engine failure on this vehicle, both consistent with the known Theta II engine defect involving premature bearing wear and connecting rod failure that has been the subject of prior the federal safety agency recalls and a related class action settlement. The failure created a risk of sudden loss of engine power while driving, which can pose a safety hazard in traffic. The vehicle was inspected by the authorized Kia dealership, which confirmed the hole in the engine block and the diagnostic codes noted above. The engine and related repair estimate are available for inspection upon request. A warranty claim for repair coverage was submitted and denied by the manufacturer, citing insufficient maintenance documentation, despite this being the vehicle's second occurrence of the same underlying defect.

I was driving out of town and when I went to accelerate and the engine had seized, the brakes had locked up and I lost power steering which almost resulted in an accident. On the dash was showing the engine, oil, and esc light, which were not on the dash before and there was nothing wrong or weird going on with the car prior to the first incident to even indicate that something was wrong. Had to get the car towed home then realized there had been a recall on the engine. Contacted the kia manufacturer and they had towed it to a kia dealership where they replaced the engine. Waited 2 Months to get my car back, the dealership let me leave with the ABS and Eps light on the dash, and couldn't give me a reason why the lights were still on. I had it for 3 days, it drove okay and now it no longer drives nor does it start. I was stranded because the car wouldnt start again giving the same issues as before the recall repair was done, with only accessories turning on. On the dash it only shows Engine, Oil, Eps and battery light. Found the Serpentine belt already coming apart and misplaced, found strips of the belt laying in the bottom of the hood. Also had found out the entire engine block ROCKS BACK AND FORTH while car is in motion. If I had driven the car any longer the belt would have completely snapped and would most likely result in an injury or worse. With the Engine movement that is also going to cause other damages to the car and more safety hazards. I have not even known about the engine recall on this car until after everything happened and when the car was purchased no one had notified me in anyway about the recall. Now they refuse to cover towing costs back to the dealership because the "5 year warranty had expired" When this in no way is my fault. Second incident was Oct. 17th 2022.

My 2011 Kia Optimas engine light started flashing and the car lost all power and had no RPMS over 1000-2000. I took it to the dealership where I was told it had a code P1326 and they replaced a knock sensor. The same day that I picked my car up from them I was going down the interstate and it shut completely off and wouldn’t crank. I had it towed back to the dealership where they said I would most likely need a new engine. A few days later they call and say the engine won’t be covered under the recall because of some hose they claim was leaking for the cooling system. They said it now had a blown head gasket which I’m not sure how because it never ran hot. This is absolutely ridiculous for customers to deal with so many delays and problems just to get the repairs on their vehicle that Kia has agreed to make. If my vehicle needed a knock sensor then obviously the damage to the motor is because of faulty manufacturing of parts and I shouldn’t have to pay for a new motor!

While operating at 65+ miles per hour on the interstate my kia optima hybrid had a catastrophic engine failure causing my car to have total loss of power. I had to safely pull over to the side of the road due to this. This engine failure occurred at approximately 97300 miles, which would still be under the original warranty, had I been the original owner. A local mechanic told me the engine was seized. After doing research about these specific types of cars I learned that the regular, non-hybrid, kia optima had recalls for engine failures so I called kia corporate to see if I had coverage. Kia corporate initially told me that my car would possibly be covered if a specific part failed (rod bearings). If this was true then I would have gone through a claims process to get warranty coverage for my car. Because of this I decided to have my car towed to a kia dealership. After a few days at a dealership I was again informed that my engine had seized (without determining why/ what part failed), but the story changed. Kia then told me that there was zero chance that my car would be covered even if the specific part had failed ( which we didn't know). I called corporate again upon hearing this news and spoke to someone who looked at the transcript/summary for my initial call and told me that what I was initially told didn't happen. They told me that I was lying to them and that what I was told in my first conversation with corporate didn't happen. Kia quoted me a new engine for 10000+ dollars (thousands more than the car is worth) and billed nearly 200 dollars for a diagnostic that likely took mere minutes. Ultimately I decided to have another mechanic put in a refurbished engine for about half the price. I believe that the deception that kia put me through was wrong and that it is completely unacceptable for a well-cared for car to suddenly die without warning.

My car loses power when I use the horn. It happens while parked with the engine on and in traffic. Initially, I thought it was faulty electrical problem because there were 3 active recalls needing to be fixed. I recently took my vehicle to a certified kia service center to get the recalls taken care of and additonally, had the A/C compressor, struts, and a belt replaced. I also described the issue of engine power loss when I use the horn with service tech and attempted to demonstrate. However, my car didn't duplicate the issue. I'm not sure if the techs tested it thoroughly during the days it was being serviced. The final detailed bill states that the car wouldn't duplicate the issue. I'm currently satisfied with the fixed recalls, A/C, belt, and other minor repairs. I'm highly concerned and frustrated that I'm still experiencing engine, acceleration, RPM, and A/C failure whenever I need to use my horn. A couple of days ago while in traffic, I had to blow the horn because a distracted driver nearly side swiped me. As a result, my car loss power. I couldn't accelerate and the transmission wouldn't shift. I ended up doing around 30mph until I made it to a safe destination. I called for help, but after I turned the car off and back on, it was as if it never happened. I'm furious about it because the distracted driver proceeded to tailgate and intimidate me out of anger. Lastly, it was not professional or caring to be laughed at when I voiced this problem at the service center. I need help and answers before something more terrible happens. The number of engine and electrical complaints are startling. I'm hoping that my issue will be taken seriously and looked into. I'm not comfortable driving my car.

Car driving at highway speed. Sudden loss of power. No crank, no start. Mechanic says the engine has seized.

Driving in heavier than normal traffic about 45 MPH. Stopped at a traffic light and engine cut off. Was able to restart, but was only able to drive less than half a mile before the engine cut off again. I completely lost power, but was able to coast into a parking lot. I waited approximately 10 minutes, attempted to restart the car (successfully!) and drove around the parking lot before traveling the remaining 20 minutes home. Called aaa and had the car towed upon arriving home. The mechanic was not able to replicate the issue and nothing was corrected. Battery and alternator were in perfect condition. Car has occasionally been hesitating while starting or while idling at traffic lights since that event.

As I was driving down the road on my way home my car lost power so I had to pull over to the side of the road after a car almost hit me from not being able to accelerate in the middle of the road. I then turned my car off and it would not turn back on.

The battery indicator light came on then while driving down the road, the battery discharge kept popping up on the display then went out. About 10 minutes further, I lost power steering. I managed to get to base even though I ran a red light and stop sign because the car started spurttering and feeling like it was getting ready to stall. Once I managed to get to a parking lot, my headlights went out but I still had dash lights. All the error lights came across my dashboard. I took the battery to advance, they said it was low. They charged it and said it needed replaced. The battery indicator was still lit so I took it and they checked the alternator and said it was dead. I took it and had it rebuilt. Everything seemed to work ok.

Driving on interstate, out of nowhere engine light started flashing and engine seized, car lost all momentum, had no "get up and go" pushing on the gas pedal did nothing, going up hill was almost impossible. Took car to local auto shop, they could hear some noise but weren't sure what. Per invoice 7/26/19: checked codes: p0011 a camshaft position timing over advanced, p00114 b camshaft position timing over advanced; p1326 engine damage alert for driver. Engine was noisey and ran very rough, oil level was low and black (we saw nowhere that it was leaking oil, no spots anywhere). Changed oil and add lucas engine stabilizer, engine quieted and runs much smoother. Clear codes, test drive, watch scan data. No codes, possible early stages of engine damage if codes return inspect timing chain and control devices. Took car home over the weekend drove less than 50 miles, sunday 7/28/19 again, engine light came on and car had no "get up and go" and a very loud clanking noise could be heard. Took car to shop asap. Per invoice 7/31/19: check cel light and loss of power, check fluids, engine has internal noise/damage; computer datascan, check codes, diag, p1326; engine damage alert for driver, recommend further diag eval, inspect lower end and timing chain. Auto shop contacted local kia dealership, was told they warrant engines with these conditions. They have a number of vehicles waiting to be repaired already, suggested calling a dealer out of town for repairs.
