The contact owns a 2021 Kia Seltos. The contact stated while driving 78-80 MPH, the vehicle started losing motive power. The contact stated depressed the accelerator pedal to the floorboard however, the vehicle failed to respond. Several unknown warning lights were illuminated. The contact was able to pull to the side of the road. The vehicle failed to restart and was towed to the residence. The vehicle was then towed to the dealer, where it was diagnosed that the engine threw a rod through the oil pan, which drained the oil, and caused the engine to seize. The dealer determined that the engine needed to be replaced under warranty; however, the part was not available. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the part to repair the vehicle was not available. The failure mileage was approximately 49,281.

Engine began knocking and would stall on turns. Check oil light briefly flashed. No oil visible on dipstick about 2000 miles after oil change. Placed 4 quarts at home and was full. Stalling and knocking resolved. Brought to dealer and they said nothing wrong. Changed oil and did 1000 mile return to dealer to check oil consumption rate. The oil was about a quart or less low and they said this was normal, nothing to do. After 2000 miles oil level again checked and no oil visible on dipstick. Took photos of oil level each of these times. Called dealer and they towed it in. They confirmed that it is burning excessive oil and said it’s several quarts low. They say that they will now try to perhaps “soak” the engine? They have to check with Kia for approval. Not sure what this means. It is now with the dealer and we have no car to drive. They are not sure how long they will have it and have no loaner. We are obviously concerned about the safety of this engine/car which has just over 30000 miles and is running out of oil prior to recommended oil changes and was stalling intermittently when this was first discovered. Obviously concerned that engine will seize and be ruined at some point in essentially a brand new vehicle. The dealer (Preston Kia) denied any issue initially. I have read about ring issues in seltos engines requiring engine replacement. It seems that a similar problem is occurring here and I hope that Kia will do the right thing and repair/replace the faulty parts/engine. There are many similar complaints on line.

While driving I noticed my Seltos felt like it was shifting hard. I then attempted to put it in reverse. There was NO reverse. I had to get bystanders to push me off the road. This is a safety risk because there were no warning signs that reverse would fail to engage. Kia states there is no recall, but several of same instances were found in forums. My car is scheduled at dealership next week. No rental, no recall, no warranty. I will have to pay out of pocket for something that has been known to fail. Supposedly an actuator of some sort. This repair will be costly and I feel it is a manufacturer responsibility. This is not normal wear and tear item. I bought this used, it was practically new. Now I know why someone traded it in. Kia should disclose their warranty limitations when they advertise. The 10 year, 100,000 mile is not a true representation.

2021 Kia Seltos possibly already had the recall work done in Florida before purchasing it used with only 18000 miles. It has stalled, once dying completely. Trouble gaining acceleration. Losing oil. Multiple oil consumption testing visits to dealership of 1000 miles each to continue showing Kia it loses over 1 quart per period. Now the glow relay engine and misfire engine codes are pulling which indicates engine damage after dealership has just last week replaced new spark plugs and oil change. It has been rough idle and ticking - knocking sound the entire time, which they denied the morning after purchase.

I've owned this car since it was new. I've been disappointed with the transmission. At low speeds, it will hesitate and shudder. This is especially true if I'm making a turn. This has been a consistent problem. Secondly, twice my transmission has overheated. The first time we were in a Halloween event during the Pandemic 2020. It was a drive-through event that was stop-and-go. The warning light came on with the gauge showing one bar over the limit. As luck would have it, the traffic started to move towards the end and it lowered the bar to just under the overheating bar. The second time this happened it was much more serious. I had four people in the car. We had just left a restaurant and were heading towards the freeway. Unfortunately, we got stuck on a hill in Hollywood Bowl traffic. We were stuck there long enough that my car shut down on the hill. We were blocking traffic and my wife got out to direct traffic around us. I tried to put the car in neutral and coast towards an open curbside parking space. It wouldn't budge. We spent what felt like an eternity blocking traffic. It was probably 4-5 minutes where we were unable to start or roll backward.

This is the 3rd time since I've had my vehicle (purchased in October of 2020) that I've had an event like this occur while driving. Currently waiting service appointment, 2 weeks away 1st incident, within the 1st 6 months of ownership, cant remember the exact date: Vehicle appeared to restart as I turned left at a green light. 2nd incident: Vehicle appeared to restart itself whilst driving on highway (thankfully no traffic/other cars on the road at this time, but I was doing 70+mph at the time). Shortly after this incident, I called the local dealer to setup a service appointment about this issue. Service was unable to to replicate issue. They looked for whatever codes that might lead them to the source of the problem, but none found. Was told to monitor bring vehicle back in if it happened again. It's seems to look like some sort of electrical/computer glitch that causes the car to do this. It happens inconsistently (different driving conditons) and infrequently, but is a major safety issue.

AQ25001 · Kia 25V099 Piston Oil Ring Recall Effectiveness

Opened Aug 6, 2025 · Closed Dec 18, 2025

Status: closed (inferred from source dates) · Engine And Engine Cooling:engine:hard Parts Internal/mechanical

On August 6, 2025, the Office of Defect Investigation (ODI) opened Audit Query (AQ) 25001 to assess the implementation of Kia America, Inc.’s (Kia) remedy program for Safety Recall 25V099, involving incorrectly manufactured piston oil rings which may damage the engine causing a loss of motive power or fire. This AQ was opened in response to consumer complaints alleging of an ineffective remedy, inconsistent inspection results to determine whether an engine replacement was needed, and the unavailability of recall remedies. On August 11, 2025, an Information Request (IR) was issued to Kia requesting: 1) why the inspection test was revised from requiring a ‘cold’ engine to a ‘warm’ engine; 2) why the recall remedy was suspended from April 30, 2025 to May 7, 2025; 3) how Kia notified customers of the recall remedy suspension and the need to re-test engines that failed the ‘cold’ engine test; 4) the number of post-recall remedy complaints alleging engine or other engine related failures; and 5) the warranty coverage Kia is offering to vehicles that passed either inspection tests. On September 10, 2025, Kia responded to NHTSA’s IR: Kia reported the change in temperature from ‘cold’ to ‘warm’ engine testing was done to increase accuracy. The inspection test uses diagnostic tools that detects abnormal engine vibrations to identify damaged engines. From the initial launch of the Technical Service Bulletin (TSB) on April 4, 2025 through April 28, 2025, ‘cold’ engine testing resulted in a higher-than-expected failure rate when compared to the pre-recall warranty claim rate. This discrepancy led Kia to re-evaluate its inspection test and found that performing the inspection on a ‘cold’ engine can result in imprecise test results due to normal cold-start vibrations. Kia revised the inspection to ‘warm’ engine testing to minimize vibration interference. Kia sampled the field and performed a comparative analysis between ‘cold’ and ‘warm’ engine testing, and validated that ‘warm’ engine testing was more accurate in identifying damaged engines. Kia also reported the suspension of the recall remedy was due to a software error in the diagnostic tool, which was introduced in concert with the April 29, 2025 launch of the TSB that revised the inspection from ‘cold’ to ‘warm’ engine testing. The software error resulted in all inspection tests reporting false positives for a damaged engine. On April 30, 2025, Kia suspended the remedy until May 7, 2025, which was when the software error was corrected with the release of the latest TSB and software update. The recall remedy remains available to eligible customers. Kia reported owners were not mailed letters concerning the suspension to the recall remedy. Kia reasoned since it resolved the issue faster than it would have taken to draft and mail letters, Kia did not want to create unnecessary customer confusion involving an issue that would have already been addressed upon receipt of a letter. Kia also determined that mailing letters about re-testing engines was unnecessary since those vehicles were already at the dealer awaiting engine replacement. In most instances, Kia Customer Care agents would respond to customer inquiries related to the recall, including remedy availability, dealer issues, and questions about differing test results. Kia provided ODI a review of engine related consumer complaints received on post recall-remedied vehicles. Kia did not find any common patterns or trends related to those complaints following completion of the recall, as the complaints included issues that were unrelated to the subject defect. To aid in the diagnosis of whether a complaint is related to the recall, the remedy includes the installation of a software program, the Piston-ring Noise Sensing System (PNSS), that monitors the engine for unusual noise patterns (an indicator of potential damage to the piston oil rings), and alerts the customer by flashing the check engine light and setting Diagnostic Trouble Code (DTC) P1327. Kia confirmed that it is not offering any specific warranty coverage for this recall. Instead, Kia has instructed dealers to replace the engine, at no cost to the customer, with no time or mileage limitation, following the installation of the PNSS software and the presence of DTC P1327. On September 4, 2025, Kia issued Subsequent Repair Action (SRA) # SC336YZ, which provided engine diagnosis and replacement instructions for vehicles with a potentially related complaint following completion of the recall. Under this SRA, customers whose vehicles set DTC P1327 will have their engine replaced. If DTC P1327 is not set and it is unclear whether the issue is related to the recall, dealers are instructed to contact Kia's Technical Assistance Center to ensure the issue is appropriately handled. Kia notes that any issues determined to be unrelated to the recall are subject to the 10-year / 100,000-mile Powertrain warranty for original purchasers and a 5-year / 60,000-mile Limited Basic Warranty for subsequent purchasers. In summary, Kia identified the insufficiencies of its initial inspection test that led to a pause to its recall campaign, explained why it did not mail letters to affected customers about the paused campaign or revised inspection test, reviewed existing consumer complaints that did not identify any potential trends related to the recall, and identified its warranty coverage for any vehicles exhibiting qualifying engine symptoms. After review of Kia’s response to the IR, ODI has determined that no further action from Kia is necessary at this time, and ODI will close this AQ investigation accordingly. The Agency reserves the right to take additional action if warranted by future circumstances.
