On 16 November 2021, Kia sent a letter for a Product Improvement Campaign to install software called "Knock Sensor Detection System" ("KSDS") on my 2018 Kia Soul Plus. The software update was installed on 4 December 2021. The 16 November letter noted that if KSDS detected a problem, the car would enter a limp home mode that limited engine RPMs to 1800-2000 RPM and the Malfunction Indicator Lamp ("check engine light") would blink continuously. On 17 December 2021, the check engine light started to blink continuously, and the engine RPMs never exceeded 2000 RPM. I took the car to the dealership on 18 December 2021. The car is not safely operable. The dealership told me that they needed technical assistance from the factory, which they have not yet received as of 3 January 2022. I'm reporting the issue because it appears to be related to the known engine manufacturing defects in Theta, Nu, and Gamma lines of engines, and that these issues persist beyond the 2011-2016 model years (for which a recall has already issued) and at least into the 2018 model year. Answers to questions: (1) powertrain/engine failure, possibly other system(s) (2) safety risk is known fire danger in Theta, Nu, and Gamma engines (3) dealer is currently diagnosing/confirming the issue (as of 1/3/22) (4) only dealer has inspected vehicle (as of 1/3/22) (5) no issues prior to 12/17/21, when Malfunction Indicator Lamp ("check engine light") started to blink continuously and engine RPMs were limited to 2000 RPM.

Buyer beware, DO NOT PURCHASE A KIA. Kept up with oil changes on the car. Purchased used in 2019 at 45k miles. While driving from work car just stopped working, and engine and oil light turned on. Electrical was working replaced battery maybe two months earlier. Wasn’t due for an oil change. Took car to a mechanic who said it was low on oil which seemed odd. Also replaced brake pads and rotors. $1000 later the car starts making a horrible rattling sound and the oil light and engine light turn on and car almost immediately dies. Took car to dealership, engine is done. This is happening to ALL of Kias cars that are being put on to the market. These cars are STILL being sold and they are all very much aware that these engines are bad. An entire decade of BAD ENGINES from Kia. And they are doing nothing. NOTHING. No recalls on this car. So now I am f*****. I have had this car for TWO years and it is only THREE years old and the engine is DONE. How is nothing being done about this???? Why are our voices being ignored?? There are complaints on this page with this EXACT issue. Why aren’t these cars being recalled?? I had my boyfriend and 3 dogs in the car, what if my car had caught on fire like their other crappy cars they have put out? Would I just be another person murdered by Kia and no one does a thing about it? (Allegedly)

Engine Failure, Started burning oil, within a month of that started knocking, after 4 weeks the connecting rod went through the block. I was driving on a public roadway. Vehicle is in for repair now for a new short block, catalytic converter (oil damage) with the dealership and being repaired by the manufacturer under warranty. Only warning lamp the car has had was about a month prior for an inefficient catalytic converter. No warnings for low oil or engine trouble prior to developing the knock. Vehicle is at Celebration Kia in Delaware Ohio for repairs. The incident date is approximate.

While driving to work in my 2018 Kia soul on 10/16/21 vehicle has a significant hesitation pulling away from a stop sign/red-light. A very slight knocking noise could be heard. the oil light flickered on and then immediately went off. Next thing I know while doing 65 on the highway the oil, engine, and battery lights all lit up then suddenly power to the vehicle was gone! I managed to get the vehicle off the highway onto the shoulder of the road where I watched smoke pouring out of the engine bay. My vehicle only has 69059 miles. the 2.0L motor that is subject to many other recalls and issues is the same as what is in my Soul. . I've only had this car for less than two years! KIA REFUSES TO DO ANYTHING ABOUT IT!!

At 94,000 miles without warning I have a rod knock. I have maintained oil changes regularly and topped my oil off before this drive. No warning lights no indicators. Just a blown engine.

I have my oil changed regularly. At about 49,000 miles, upon braking, the oil light came on. When accelerating the oil light would go off. I checked the oil and it didn't even register. I added 2 quarts of oil to bring it to the mid line of dipstick. Took the car in, and had oil changed. 3 weeks later, at 50,000 miles, the oil …

I have my oil changed regularly. At about 49,000 miles, upon braking, the oil light came on. When accelerating the oil light would go off. I checked the oil and it didn't even register. I added 2 quarts of oil to bring it to the mid line of dipstick. Took the car in, and had oil changed. 3 weeks later, at 50,000 miles, the oil is now a 1/2 quart low. Took car in to the dealer. They told me that the oil consumption of 1 quart every 1,000 miles is within normal range. This is ridiculous. I should not need to add oil to a 3 year old car between oil changes.
