RECALL EVASION & TIMELINE FRAUD REPORT Filing formal complaint against Kia America & Kia of Cerritos (CA) for evasion of mandate under Safety Recall SC336 (the federal safety agency 25V099). 1. CRITICAL TIMELINE: • [XXX]: Kia Cerritos confirmed NO diagnostic/recall tests were performed. • [XXX]: Dealer documented engine is completely SEIZED from the "bottom part" (where recalled piston oil rings reside). • [XXX] Kia Corporate denied repair, claiming the vehicle failed/passed an electronic KDS vibration test. 2. TECHNICAL IMPOSSIBILITY & FRAUD: It is mechanically impossible to run a noise vibration test on a seized engine that cannot crank or turn over. Either Kia Cerritos falsified records or Corporate is fabricating diagnostic data to evade a mandatory recall. 3. UNLAWFUL WARRANTY CONSTRAINTS: Kia Corporate is trying to route this federal safety recall through standard powertrain warranty rules, denying coverage over a lack of private cash maintenance receipts. Under federal law, safety recalls cannot be conditioned on consumer maintenance history or second-owner limits. 4. VIOLATION OF FACTORY PROTOCOL: Page 2 of Kia’s official SC336 TSB explicitly commands that a 'Seized / No Inspection' engine status must bypass the electronic noise vibration test entirely and be fast-tracked to corporate Techline for a full long-block replacement authorization. REQUESTED ACTION: I request the federal safety agency Recall Enforcement Division immediately investigate Kia Corporate Case Number [XXX] for recall evasion and compel Kia America to authorize a free long-block engine replacement. "Note: This complaint is being managed by the driver's son-in-law and authorized representative [XXX] due to a language barrier."

Piston oil ring recall update complete in July 20 25. A month later key fob battery dies. Replaced key fob battery every other month since recall. September 20 25 had brakes and rotors changed at dealership since then anti-slip alert has triggered twice on dry roads. Light comes on then immediately goes off. Remote car starter stopped working in December. Dealership had no resolution for key fob issues and has not been able to replicate anti-slip issue. Dealership currently has vehicle to attempt to replicate issue and to look into the remote car starter issue. This is unsafe because the car automatically shutters and feels uncontrolled slip comes on also causes issues when key fob consistently dies every other month and get alert, letting me know that the key fob has died. And while the remote car starter is not a safety issue, it is all tied in with the electrical issues that are happening. The issues started after the recall was added to my vehicle.

Kia issued a recall for defective piston oil rings. The recall was performed on my 2021 Kia Seltos and showed that I needed an engine replacement. The day that the dealership tested my car Kia suspended the recall stating the test was inaccurate. When the recall test was reissued my car passed and was denied for a new engine. An oil consumption test was performed on my car and the results were that my Seltos goes through 2 quarts of oil every 1,000 miles. Kia will not do anything because I do not have records of 1 oil change that was done at my home. The recall stated the car is at risk for a fire hazard because oil could be seeping places it is not supposed to be. The car will also shut off while being driven if the oil gets below 2 quarts low.

I brought my vehicle to the dealership due to serious safety concerns, including the engine randomly shutting off while driving, sudden unintended acceleration, unresponsiveness when pressing the gas, difficulty turning the key to start the engine, loud noises while running, and the engine, battery, and oil lights coming on. This is the second time I’ve brought the vehicle to the Kia dealership for the same issue. The first time, I was told the transmission had been replaced and the problem was resolved. However, the same issue resumed shortly after I got the car back. I called the dealership that day but they were already closed, so I dropped the vehicle off the next morning when they opened. At drop-off, I was told no repairs could begin until the recall was “officially” announced, but that they would look into the issue and keep me updated. Unfortunately, I never received any updates and had to reach out myself multiple times. This morning, I was told the sensor lights showing were “old codes” and that everything seemed fine. They said they’d take the car for a test drive and that I’d have it back by the end of the day. No one called me back. I followed up around 4:30–5:00 PM and was told the service department had closed, but the notes said that after the test drive, more codes appeared and the vehicle would require additional work. When I first dropped the car off, I was told I’d have it back the next morning, and if not, I’d be provided with a rental. Neither happened. When I expressed that I didn’t feel safe driving the car—even if the test drive went well—especially after a mechanic told me he wasn’t sure how to fix the current recall, I was dismissed. As I was saying, “Okay, just call me after the test drive so I can come by and check it out,” Greg hung up on me mid-sentence. This entire experience has been frustrating and concerning given the nature of the issue.

While driving on the local street prior to entering the freeway, the vehicle completely stalled without any notice. Attempted to step on the brake pedal, however, there was no response. Had to use the emergency brake to stop to a safe spot. Had I been driving on the freeway, the end result would have resulted in possibly a fatal crash. While the vehicle stalled, I noticed 3 light indicators were lit: Charging System Warning Light, Engine Oil Pressure Warning Light, Malfunction (Engine Malfunction) Indicator Lamp. Keep in mind, all maintenance and services were up to date including oil change, which had been performed at KIA dealership service. The gears were then changed from "drive" to "park" and attempted to restart the engine. Engine turned back on without any light indicators on the dashboard and assumed that it might have been a minor electrical issue. Attempted to drive back onto the road and then the engine completely stalled again, however, this time the brake pedals responded. Not to mention, there were consistent rumbling sounds coming from the engine after the initial engine stall. Called KIA's roadside services for tow services and after 6 hours, the car was towed to a local KIA dealership to Valley-Hi KIA located in Victorville, CA. Received a call today from the dealership (June 4th, 2021) this morning and was informed that there was no oil in the vehicle and was charged $44.99 for the oil fill. Was told that there was no evidence of oil leakage and was advised to drive the vehicle 75 miles back home to take to a local KIA dealership to run an "Oil Consumption Test." Texted "Stacey Keen" at the dealership the article regarding this recall for 2021 KIA Seltos for a defect in the Piston Oil Ring and asked to speak to the service manager. Current status: Did not receive any text or call back from the dealership and was told that I will receive another update this upcoming Monday to see if the vehicle will have oil left in the vehicle.

While driving on the highway, the vehicle failed to accelerate. On a road where the speed limit was 60 MPH, the vehicle stopped accelerating at 55 MPH suddenly and caused disruption in the traffic until I could cruise to the shoulder in neutral. It was a scary situation where multiple accidents were narrowly avoided. The vehicle was towed to the dealership where the transmission was identified to have a broken transmission with 3000 miles on it.
