The dealership installed the knock sensor in my car in November 2022 due to recall. Yesterday 12/12/22 when I left work, my car knocked so loudly the whole car was shaking. The car slowed and the check engine light came on. The car slowed while I was in process of accelerating to get up to speed on a busy urban street. There were several cars and I was afraid I was going to get hit due to the sudden deceleration. My car was towed to a Kia dealership. I was told it would be one to two week before they could even do a diagnostic on it and they could not give me a rental. I’m paying a car payment for a car that has broken down multiple times. The dealership said they were having a lot of cars being brought in because kids were stealing them after watching a tik tok where they’re shown how easy it is to steal a Kia and taking the cars for joy rides and wrecking them. When I took the car to the dealership in November, they didn’t fix anything, only put the knock sensor on. Now, just a few weeks later, its knocking and and the sensor is going off. I told them it sounded odd, knocking sort of when I found out about the recall. I bought this car because I needed a more dependable car. My other car was getting older and I am getting older and have health issues. I do not feel safe in this car with all the problems I’ve had.

For many months car has been randomly stalling. It has never been able to be duplicated at dealership, therefore it hasn't been addressed. In recent weeks the stalling is more often and is now accompanied by a check engine light.

At around 91, 697 miles, our 2020 Kia Soul EX began to have issues with the engine stalling out while downshifting in lower speeds, We took our Kia into the local (still an hour away from our home) dealership, for the recall "fix" which involved uploading a firmware update to the ECM for the knock sensor. We also had the dealership look into the issue of stalling out, but they could not replicate the issue and therefore sent us on our way. About two weeks later, the vehicle started making an extreme knocking sound (I am a mechanic and knew what the issue was immediately), and it brought up a check engine light, however there was no oil light or warning of any kind that came on. Upon further inspection, it was discovered that there was no oil in the vehicle. Upon filling the vehicle back up with oil, everything seemed normal, until the weekend of 11 October, when the motor again had an extreme amount of oil consumption, to the point of the same symptoms, along with a loud rattling sound, as if something had broken due to lack of lubrication, despite having an oil change completed less than a month prior, with approximately 1200 miles due to the next oil change. This almost left us stranded approximately 1.5 hours away from home. Again, we filled the engine with oil, and drove with extreme caution as the check engine light never shut off. Again, no oil light or indication the vehicle was experiencing a no-oil condition was present. After getting an appointment and taking the vehicle into the dealership on 20 October 2022, the technician stated that there were multiple CEL codes, including P0017 Crankshaft Position, multiple cylinder misfire codes, and low compression on cylinders 2,3, and 4, with cylinder 2 being the lowest. It was deemed that the top end of the motor looked good, with no obvious signs of neglect in maintenance, or issues that may cause false codes. The vehicle continues to exhibit stalling, and low acceleration, posing a severe safety issue.

NHTSA investigations
1DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
