2021 KIA SELTOS Complaints

This is supplemental information for my existing Complaint #XXX – 2021 Kia Seltos SC336 / 25V-099. Key facts and timeline: Purchased as Certified Pre-Owned on August 17, 2025 from Rairdon Kia of Burlington. Safety Recall SC336 / 25V-099 performed June 24, 2025 (mileage 61,378). January 15, 2026 oil change performed at Smith Kia of Bellingham (R.O. XXX). April 2, 2026: Sudden severe loss of power at highway speeds on I-5 North with flashing check-engine light. Vehicle returned to Smith Kia (R.O. 57763, mileage 71,703). Service Advisor Sebastian Goulding confirmed the engine was 3 quarts low on oil and provided a hard copy of the active DTCs P132700 (Piston Noise Detection) and XXX (System Too Lean – Bank 1). Smith Kia performed only an oil change and cleared the fault codes. Please see the attached detailed PDF timeline and supporting documents (fault code history showing P132700 and P017100 still listed in “History” state, Smith Kia records, Rairdon Kia $244 improper diagnostic invoice, and NHTSA confirmation).

This has happened 3 other times. It just stalls out when stopped. Not to do its SMART thing but it clunks-like and turns completely off. Its a bit scarey. And now heat issues just like the last 2 summers. It has issues!

Vehicle: 2021 Kia Seltos VIN: [XXX] Mileage: 71,728 Recall: NHTSA 25V-099 / Kia SC336 (piston oil rings) – Subsequent Repair Action SC336YZ On [XXX], while driving at highway speeds during a trip from Everett to Bellingham WA, the vehicle suddenly lost power, the check-engine light came on, and it set DTCs P132700 (Piston Noise Detection) and P017100 (System Too Lean – Bank 1). The engine was documented 3 quarts low on oil. This is the exact failure mode described in the recall: defective piston oil rings causing oil consumption, engine damage, and loss of motive power. The nearest dealer (Smith Kia of Bellingham) performed only an oil change and cleared the codes, then declared the car “good to go.” The vehicle was then driven 20 miles to Rairdon Kia of Burlington, WA (the original selling Certified Pre-Owned dealer), where it is now located. Rairdon Kia states they cannot perform the full engine long-block replacement under SRA SC336YZ because the codes are no longer active. Kia USA Customer Care (Case #[XXX]) called today and stated they are “taking the side of Smith Kia”. They suggested getting another dealer’s opinion. We are now being told we must drive the vehicle until the code re-triggers. My wife refuses to do so. She is extremely upset and afraid of getting stuck on the side of the road or causing an accident due to sudden loss of power at highway speeds — exactly what happened on [XXX]. This situation is now causing significant stress and disruption in our personal life.This is a federally mandated safety recall that was supposedly completed before our CPO purchase ([XXX]) with no disclosure. The temporary oil change and code clear did not fix the underlying defect. We request that NHTSA require Kia to immediately authorize the full engine replacement at Rairdon Kia based on the documented history, without requiring us to drive an unsafe vehicle.

On April 7, 2026, the vehicle experienced a 'quiet fade out' stall while in motion, resulting in a total loss of motive power. The dealership (DCH Kia of Temecula) confirmed cylinder scoring and referenced Techline Case 26022952. This failure is identical to the conditions described in the NHTSA Campaign 25V-099. The dealership is currently refusing to classify the repair as a Campaign Repair, which would include the mandated Lifetime Engine Warratny, and is instead attempting to process it as a discretionary 'Goodwill' repair to avoid federal safety requirements.

I have a Kia Seltos 2021 AWD EX 24,700 mi. that was recalled and new engine put in on April 12th 2025 to fix grinding noise that occurred 4 times the end of March starting on the 17th 2025. On Dec. 12th 2025 Grinding noise started again. Couldn't find anything wrong and told them to try harder. Said needed software update back to what it was before engine put in. My problem: I don't have the 5 year extended warranty that I thought I had. Never got papers about warranty of new engine which I don't think it is. No papers saying if they ever checked to see if parts affected by grinding had shown wear. Neither dealer where it was serviced had done this to my knowledge and won't give written proof. I never had a copy of any of the paper work I signed in front of me the 3 ½ hours in office. He would go over and tell me to initial or sign. Then didn't want to give me a paper copy but put on zip drive. I insisted on paper and about a ½ hour late he came with 28 pages of mostly size 6 font. I just wanted out. They have known this car has had issues since the day I bought it. I have called customer service dealer and corporate. According to paperwork Im not allowed to ask for a jury trial, go to arbitration or join a class action suit nor get reimbursed for repairs caused by defects. I went to Sr. vs. Crime and they tried to call to get paperwork and they didn't return calls. What options do I have left as the ods of needing repairs seem obvious. My car is worth nothing - bad reputation, and I don't feel safe driving it.

The contact owns a 2021 Kia Seltos. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power with the check engine and traction control warning lights illuminated. The vehicle was able to restart; however, the failure recurred. The vehicle was initially taken to an independent mechanic and then towed to the dealer. The dealer diagnosed the vehicle and retrieved DTC: B001400 and P00A0. The contact was informed that the piston flap and cylinder #1 had failed, and that the engine needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 46,803.

On April 4th 2025 I received a letter concerning NHTSA Recall 25V099 and was asked to have dealership run diagnostics. On April 30th dealership says "YES" engine needs to be replaced. Two days later dealership calls me and says new software has arrived and they need to run diagnostics for recall again, this time on May 16th 2025 car passes. NOW, almost one year later and after warranty has expired, the car has a DTC P1327 which is noted in the recall letter and the car will NOT start. Had it towed to nearest dealer and they say since the original dealer "Passed" the recall, I have to pay to get car looked at again. It is obvious to me their original diagnosis missed something and now I just want my vehicle back, but it won't run because of the P1327 DTC and of course the dealership where car is now says since I did not buy it there, nothing they can do? KIA service is TERRIBLE.

Excessive oil consumption Engine damage or failure Ticking noise from the engine Loss of power when driving Rough idle, shaking the car is not able to be used, for safe.

While driving engine shut off and car will not start. Garage states engine is seized up. It is same engine that Kia recalled
