Engine Failure after KSDS in March 2022 Update Error Code P1326 (2 times in May and June 2022), BSDS Error with HEV Warning Light Shut Off Engine to prevent damage. Engine burned 2.5 quarts of oil in 3 weeks and 1500 miles. Vehicle went into -??limp mode-?? or -??safe mode-?? to prevent further damage. Engine failure at 102k miles. Error is currently being added by KIA North Austin. KIA reproduced the error P1326.
The contact owns a 2017 Kia Optima. The contact stated that while operating the vehicle the low oil level warning light flashed and occasionally the vehicle would not properly respond while depressing the accelerator pedal. The contact checked the engine oil dipstick and discovered that there was very little oil in the engine. The vehicle was taken to the local dealer who performed an oil consumption test and indicated that the vehicle was consuming one quart of oil per one-thousand miles and that the rate of consumption was within a normal range. The vehicle was not repaired. The contact stated that since the oil consumption test was performed the failure had become progressively worse. The manufacturer was notified of the failure. The failure mileage was 50,000.
This has happened 3 times driving car almost comes to a complete stop. Acceleration dropped down to 20 MPH. Was told it was a knock sensor replace in March in May did it again. Replaced it against the very next day it did it again. Went online and said it was a recall but nothing is showing up here. I will contact Kia in the morning we could have been killed this happened in the expressway
I was driving on the highway when my check engine light came on flashing the car jersey almost to a stop and I had to pull over. I cut the car off and sat then turned it back on. The check engine light was still flashing and I put my flashers on and was unable to go over 60 mph. I drove slowly to an autozone and a code was pulled p1326. I looked it up and it undeliverable due to the knock sensor issue.
March 2022, (approximately 72,000 miles)while driving to work my car shut off. I was in drive at a red light. Noticeable decreased acceleration and vibration. Took it to the dealership for routine oil change and mentioned incident. Technician was not able to find cause. Ok so be it. Now May at a little over 73,000 miles multiple lights began to illuminate and flash. Still with decreased acceleration it was noticed on a Friday morning on my way to work: 1. Oil light flashed on and off for approximately 2 minutes. 2. Air bag light stays on 3. Electronic Stability Control light stays on I scheduled an appointment for the next day. Took it into nearest Kia dealership. I was informed that my engine had no oil in it. The electrical board that signals my airbags and power steering is -??malfunctioning-?? and would need to be replaced. I was also told that since I just went for an oil change and was not due for another 3-4,000 miles maybe the -??engine absorbed the oil as there are no visible leaks-?? I am set to return to Kia at the 1,000 mile mark to check oil levels to see if the oil is gone again. On my way to work again, on I-75 I felt extreme unsteadiness and loss of road grip with steering. Like I was loosing co trio of the vehicle while traveling at 55 miles an hour. As the original owner of this vehicle, with regular routine maintenance this is extremely concerning. I worry every day that my car will fail me and injure mine, my kids and others lives. I really hope this is looked into as a safety issue.

EXCESSIVE oil consumption. More than 1 quart every 1,000 miles. I am having to change my spark plugs about every 3 months to keep this car going. I've been to Kia twice and spent thousands of dollars. It has fixed nothing.
Large Oil consumption (1qt a week). No warning lights, experiencing loss of power, hesitation on acceleration, oil covering the motor with no signs of leaks underneath the car on the streets. Oil puddling up on the top of the valve cover near the plugs but unable to locate the source. Gaskets and hoses checked and all are in good condition. 125,000 miles.
Engine is consuming excessive oil. That could cause internal parts of the engine to wear faster because of less lubrication and could lead to an engine failure while driving, which could lead to engine stopping and loss of propulsion which could cause an accident. The car went through a oil consumption test with a Kia dealership and failed by consuming more than 1 qt of oil in a 1000 miles interval. The Kia dealership proceeded to do a combustion chamber cleaning procedure and re-did oil consumption test and it failed again. They also had requested service record which where provided. Even though Kia has a service bulletin on that matter, the service advisor at the Kia dealership said that the manufacturer declined the claim. Right now I-??m constantly refilling oil in the engine which is also an additional expense. The first time I noticed the issue was in February, 2022 when the low oil pressure alert came on.
The Engine burns oil at a rate higher than the recommended oil change interval. I have had the dealer perform multiple consumption tests. The car passed all three even though it burns around a quart every 1000 miles. I had them clean the combustion chamber and paid for the costs myself but that did not resolve the issue. This seems be a known defect in the engine and is causing me a lot of problems monthly. A recall needs to be issued to fix this problem.
We bought the car used in November of 2020 from Conicelli used Toyota dealership. We had the car not even a year when the engine broke and we got it looked at and found it was a rod knock which there is a recall for this vehicle for the same issue we were having. We had the car towed to kia on the boulevard on January 3rd of 2022. It is now March 8th 2022 and they keep telling us different things at first the engine was supposed to be there by the 6th and now i called today and sat on hold to find out that the advisor for the car no longer works there and now the engine still isn't there and they have no idea what's going on and have to look into it. this isnt the first time we were told that the advisor no longer worked there it happened with the first advisor and were now going on our third advisor.
Oil consumption in my vehicle is well above 1 qt per 1000 miles. This is a known problem but Kia engines and Kia doesn't take responsibility for it. The oil light never comes on and the car runs out of oil every 1500 miles. It's not leaking, it's being consumed. Kia does not see it as a problem, even though there are so many reports. Please expand the recall for 2017 Kia's.
I had got on the freeway when I got to my destination I got off the freeway and was waiting for the green light my car started shakeing and shut off. I was able to turn it back
During the week of November 14th, 2021, I noticed my vehicle begin to noticeably vibrate and generate an unfamiliar sound near the engine compartment. The vibration and sound was accompanied by a "check engine" light illuminating. I immediately scheduled an appointment at my local dealership and was provided a date of November 29, 2021. On November 29, 2021, I dropped off my vehicle at the dealership and learned of NHTSA Recall Number "21V844." The service representative and his technician believe the vibration and sound are a result of the recall. To date, my vehicle remains at the dealership and the matter is unresolved. The service representative has advised me that Techline / KIA Corp. is determining whether my vehicle's engine issue is due to the recall or not. It has been two weeks that the vehicle has been at the service center. As per the recall notice I received in the mail, the inspection for the recall should have been completed in a matter of hours. I reasonably believe that Techline / KIA Corp is searching for an excuse to not remedy my vehicle's engine issue, and are jeopardizing the safety of myself and my family. I have a newborn and kindergartener that I have in the car daily and am concern for their safety if the engine issue does not get fixed. I am a military veteran and active police officer. I appreciate any assistance you may provide and thank you in advance.

Unknown -?? Right in the moment I started the car. My car turned on the check engine light and it started a fault as if it wanted to turn off, it shakes and the engine works without power. Since that moment it-??s doing it constantly.
My Kia Optima was burning three (3) quarts of oil for every 1,200 miles driven. I brought the vehicle to Willowbrook Kia and they stated that they would need to do an oil consumption test. After the 1st test, it showed that I burned 3 quarts after 1,200 miles driven. Kia completed an intake carbon test and had me drive it for another 1,000 miles. After the 2nd test, it showed that I burned 1.5 quarts of oil after 1,000 miles. Willowbrook Kia stated that the engine needed to be replaced and it will be under warranty. They rented me a car which they paid for and it took me to call after 1 week in a half and they stated that the vehicle is not covered under warranty as I am the 2nd owner of the vehicle. The gentleman (Vic) at Kia told me the only way to get Kia to replace the engine is to drive it until their is no oil and the engine seizes. I explained to him that I drive on the expressway everyday and that is kind of like an accident waiting to happen. No accident has happened as of yet, but thought I would at least try and send a complaint your way. If there is nothing that can be done, I completely understand, but was trying to avoid a possible accident in the future.

The contact took the vehicle to an independent mechanic and was informed that the engine knock sensor needed to be replaced. The contact called the local dealer and made them aware of the failure. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 18V907000 (Fuel System, Gasoline, Engine) however, the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 68,000.
My 2017 Kia Optima Hybrid began losing oil rapidly (more than 1 quart a week), and then knocking. There was never a warning light or an engine light. The mechanic at Kirby Kia (the dealership) confirmed engine knocking in the lower pistons. Kia will not honor the 100,000 mile drive train warranty because I am the second owner, and there is no recall on the hybrid engine. However, it's irrelevant that they won't cover the cost of the engine since they are not making engines available to anyone outside of the recall, so I cannot fix my car. I'm a little confused on why this engine is withheld for the recall, but mine is not recalled.
Engine has too much oil consumption, went to do my oil change 200 miles before it was due and the automotive place told me there was no oil on my drip stick. Also have a rattling noise in my engine when I accelerate. Noise has been happening for a few months but they can't seem to find a problem.
The wiring harness was replaced in my 2017 Kia Optima in 2019 at approximately 45,000 miles. Kia replaced my engine January 2020 because it was consuming large amounts of oil. I just got my car back in January 28, 2021 with a supposedly new engine. On March 3, 2021, my car caught fire while pulling out of my neighborhood actually driving down the street. Smoke and flames were coming out from underneath the hood the of the car. The entire front end of the car burned. Thankfully, the fire department got the fire out and no one was injured.
