2016 Kia Optima Engine Problems

Car is not holding oil it acts like it's gonna cut off while driving and it jerking was diagnosed with colitic converter p0604

Engine oil light doesn’t work. Oil light flashed a couple of times in separate instances. Checking oil dip stick which smells like burning oil and dip stick hardly showed any oil left.

engine light start blinking out of no where and speed started to reduce while on the highway. my fix finder gave me code P1326

2016 Kia Optima engine locked up, vehicle stalled on interstate,heard a rod bearing sound, left me in limp mode trying to get out the way of 18 wheelers traveling behind me. Towed into Kia dealership which confirmed the engine locked up which has a recall #PI1802B KSDS, but denied to cover it because I didn't have this recall done. I also called Kia Customer Service, they denied me too and just gave me a case #[XXX]. I explained to them that I never received notice of this recall. So how could I prepare for something like this to happen while traveling from Texas to Louisiana to visit my grand kids. The dealership gave me a Quote of $9735 for parts and labor, which I don't have, I am still making payments on this vehicle. Now I am stuck in Louisiana with my vehicle, also it's going to cost me even more to have it towed back to Texas. Please help me understand why the dealership won't stand behind a safety recall or what one person I spoke with called a campaign recall, which ever! That I never received notice about this recall. I hope the "President" or the "President of the Company" will step up and help, after all we as Citizens don't have a problem spending our hard working money on purchasing these vehicles from the dealerships, to have things like this to happen out of our control. Thanks for at least Listening. GOD BLESS...INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2016 Kia Optima. The contact stated that while driving at an undisclosed speed, the vehicle shuddered. No warning lights were illuminated. The vehicle was taken to a dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and stated that the knock sensor needed to be installed prior to the failure for the engine replacement to be covered under warranty. The failure mileage was approximately 143,000.

The engine stalled without warning while I was pulling out of my driveway into the street, creating an unsafe condition due to sudden loss of power. After waiting briefly, the vehicle restarted and was moved back into the driveway. It was towed the following day due to loss of confidence in safe operation. The vehicle was diagnosed with engine failure consistent with known defects affecting Kia Optima vehicles equipped with Theta II engines. Kia denied coverage under the extended engine warranty / class action settlement solely because the KSDS (PI1802 ECU update) had not been installed prior to the failure. As the second owner, I was never notified of this update before the incident and had no opportunity to complete it. This failure was sudden, unanticipated, and safety-related. I am submitting this complaint to document an engine stall and loss of power condition posing a safety risk.

My vehicle’s engine was previously approved for replacement under the lifetime engine warranty associated with the settlement, confirming that my vehicle falls within the covered class. However, I am now experiencing significant difficulty obtaining assistance regarding secondary damage that directly resulted from the engine failure, specifically the failure of the starter and related operability issues. Despite multiple attempts to resolve this matter through the dealership and warranty channels, I have been repeatedly redirected without meaningful assistance or clear resolution. I have also encountered discrepancies within the online settlement VIN verification tool, which appears inconsistent with Kia’s prior acknowledgment of my vehicle’s settlement-related coverage.

While driving my 2016 Kia Optima, the vehicle experienced a sudden and complete loss of engine power and stalled without warning. At the time, I was Door Dashing for income. The engine seized and the vehicle came to an immediate stop in the middle of 4925 Wolf Creek Dr SW, Atlanta, GA, a narrow two-lane road with limited street lighting. I was forced to remain stopped in the roadway in darkness for over an hour while multiple oncoming vehicles passed by, creating a serious safety risk. The vehicle could not be restarted and had to be left on the roadside overnight. The following day, the vehicle would only start briefly when jump-started, ran for approximately 15 seconds, and shut off again. It could not move and was towed to an authorized Kia dealership. At the dealership, technicians jump-started the vehicle, performed diagnostics, added engine oil, cleared codes, reset adaptive values, and conducted a test drive. During that test drive, the engine seized again, and the vehicle had to be towed back. Kia approved a full engine replacement under its extended engine warranty, acknowledging engine failure consistent with known defects. However, after the engine replacement, the vehicle would not start at all. Kia stated oil intrusion from the failed engine damaged electronic components, leaving the vehicle non-operational. Kia denied coverage for the resulting damage and issued an estimated $6,000 repair bill for engine harness, injector sub-harness, and ECU replacement. The vehicle remains inoperable following an approved warranty repair. This incident involved sudden loss of propulsion while driving, occurred without warning, resulted in repeated engine seizure, and left the vehicle disabled in traffic at night. This appears consistent with known Kia engine defects and presents a serious safety concern that warrants investigation.

The contact owns a 2016 Kia Optima. The contact stated that while driving approximately 40 MPH, a knocking sound coming from the engine compartment was heard, and the check engine warning light illuminated. The contact further stated that while driving at approximately 80 MPH, with the cruise control mode engaged, the vehicle started to stall and failed to exceed 30 MPH. The contact stated that the cruise control became inoperable, and the check engine warning was flashing. The vehicle was restarted; however, the vehicle continued to hesitate and failed to exceed 30 MPH while driving. The dealer was contacted, but the vehicle was not diagnosed or repaired. The contact was referred to the NHTSA hotline for further assistance. The manufacturer was not made aware of the failure. The approximate failure mileage was 70,000.

Car is burning a lot of oil, took to dealer went through several tests and they claim burning 1.5 quarts was within limit for 1000 miles. Then started getting misfire codes and car went into limp mode a couple of times. They said to replace spark plugs because they were fouled and clean injection. Performed those requested actions, then 45k later getting misfire codes again, took to another dealer they said plugs are fould and clean injection again. Asked them to provide a permanent fix for the issue so the car does not keep fouling out the plugs and they said the only way to fix was to replace the motor. I asked, since you have no guaranteed fix why don't you replace the defective motor under warranty. They said because it is not locked up or throwing a specific code detecting a knock in the motor. So I said the motor will have to completely fail before a replacement would be approved they said yes (basically suggesting I somehow blow up the motor). This is wrong, a product under warranty from manufaturer and cannot be fixed without replacing the part should be covered. I do not know what my options are at this point, the milage warranty has run out and they will not do anything to fix it, just bandaids until it dies. the dealers would not put it in writing only verbally telling me.

The engine lost cylinder 3, piston came loose and broke the spark plug. This happened because the rod bearing came loose which has been a known issue with Kia. There’s already been a class action law suit, and recall with warranty. Now the Kia dealership in Lynchburg has refused to honor this warranty. Stating they can’t do the required rod bearing clearance test because the engine doesn’t have compression. The engine has no compression because the rod bearings came loose and shoved the piston into the head.

My engine blew up and started smoking while driving

Car stop accelerating when I went to get my oil change the shop reported my engine eating up my oil found out kia have a recall on engine

The contact owns a 2016 Kia Optima. The contact stated that while driving at various speeds, the vehicle suddenly stalled. After restarting the vehicle, the vehicle operated normally. The contact stated that the failure had occurred on several occasions. The cause of the failure was not yet determined. The local dealer was notified of the failure, but no assistance was provided. The manufacturer was not notified of the failure. The failure mileage was 100,000.

Engine sludge and failure. Engine part failure p0010 began happening within 1 year of Kia engine replacement. It is available for inspection. This creates a problem with acceleration in the vehicle, putting my family's and my safety at risk. This problem has been confirmed by the dealer. The check engine light is one. This part failure and engine sludge (despite consistent maintenance) has caused engine failure again, just 3 years after replacement.

Engine Is knocking that happened when I took my car 3 times to emission test and my car didn't pass after that I took it to my mechanic for the diagnostic and he told me you have to take it to kia dealer but I was shocked the way how they treated me and they completely refuse to replace my engine they came up with too many excuses and I have recall repair active I have right to fix my car but they didn't with bad attitude

The engine is starting to fail causing issues such as being able to accelerate. When driving on the freeway it caused a safety issue it began slowing down on the interstate. The vehicle has been inspected by mechanics. No warnings prior to problem. They appeared day before due for an oil change. The car also burns oil really fast sometimes causing car to smoke. I have a GDI turbo engine and have been told that the engine i have has been recalled a few times on different models cars.

The contact owns a 2016 Kia Optima. The contact stated that while driving at 45 MPH, there was a misfire coming from the engine, and the vehicle was shaking. There was no warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The vehicle was diagnosed with engine failure due to piston rings failure, causing coolant intrusion into the engine. The contact was informed that the engine needed to be replaced. The contact stated that the ignition coil, cylinder #1, and spark plugs were replaced. The dealer was contacted, but had not diagnosed or repaired the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

Engine began jumping during driving and loss power. No dashboard illumination warning lights and the temperature gage showed normal operating temperature. Car was not accelerating properly. Had to maneuver carefully to prevent being ran over. Engine light illuminated showing misfire. Replaced ignition coil pack and spark plugs. Driving again, car stalled. No dashboard warning lights. No high temperature on gauge. Narrowly missed being hit by a semi as there was absolutely no warning and we were on an Interstate bypass ramp with nowhere to pull over!! Towed car to dealership for diagnosis. Results: engine blown, turbos gone, and the catalytic converter is holding oil. Dealer is stating this is not covered under the extended warranty from Kia as its not connector rod bearing issues and that the piston rings failed. However, they stated the turbos got "too hot" and they failed. The gauges have never shown that the car was running hot. I have a sworn statement from my mechanic stating this is absurd and a valiant attempt to not pay for what would be the second warranty replacement of my engine. The piston rings failed as a result of the connector rod bearing failure. The "too hot" temperature that damaged the turbos was likely caused by the same bearing issue. The heat from the bearings unseated the piston rings and allowed the engine to dump its oil causing the engine to fail. I highly recommend that you open an investigation into these issues. The car not accelerating and losing power at interstate speeds is a very serious and dangerous issue.

I’m experiencing severe oil consumption and spark plug fouling, which are known problems with the GDI engine. This is affecting driveability and may indicate piston ring or valve seal failure.
