2015 KIA SORENTO Complaints

I was driving on the highway when I proceeded to the turn lane to turn left crossing two lanes of traffic and the vehicle just shut down no warning whatsoever no check engine lights no oil lights nothing and it wouldn’t turn back on when trying it but after about 5 times it turned on and I was able to get it off the highway but couldn’t go any further as the vehicle was making a loud noise and the car was shaking

The contact owns a 2015 Kia Sorento. The contact stated that while driving approximately 40-45 MPH, the vehicle stalled. There was no warning light illuminated. The vehicle was pulled over to the side of the road. The contact attempted to restart the vehicle, but the engine made abnormal knocking sounds. The vehicle was towed to the residence and failed to restart. A mobile technician diagnosed the vehicle with engine failure. The vehicle was not repaired. The dealer and the manufacturer were not contacted. The failure mileage was 98,954.

I am filing this complaint regarding a suspected safety defect involving the Theta II engine in my 2015 Kia Sorento. The vehicle developed progressive engine failure symptoms including: Engine knocking and abnormal mechanical noise Loss of power while driving Misfire conditions Excessive oil consumption Progressive deterioration of engine performance These symptoms began at approximately 150,000 miles and worsened over time. Given the documented history of Theta II engine failures involving rod bearing defects, sudden engine seizure, loss of power, and fire risk, I believe my vehicle is experiencing a progression of the same known defect. 2) Safety Risk to Driver and Public The engine condition created serious safety risks, including: Potential sudden engine failure while driving Loss of power in traffic or at highway speeds Increased risk of collision Potential fire hazard associated with Theta II engine failures Despite these risks, Kia and its authorized dealership advised me to continue operating the vehicle. I was explicitly told to “drive it until it fails.” This guidance was given despite Kia’s documented knowledge of Theta II engine defects and associated safety hazards. 3) Manufacturer Response and Denial I reported the engine failure to Kia and its authorized dealership. Kia denied coverage, stating: The vehicle had “too many miles,” and The failure was allegedly “not rod bearing related.” However, Kia and the dealership refused to provide: Complete diagnostic trouble codes (DTCs) Technician notes or inspection reports Compression or leak-down test results Oil analysis or evidence proving bearing failure was ruled out Without this information, Kia’s conclusion that the failure is not related to the Theta II defect is unsupported and unverifiable. 4) Concern of Misdiagnosis and Defect Misclassification Based on the symptoms and known Theta II failure patterns, I believe Kia may be misclassifying a progressive bearing-related engine failure as a non-covered

Formal Complaint on Seized Headlight Sockets and Kia’s Obstruction of Essential Safety Maintenance 1. Incident & Discovery of Defect: I am the owner of a 2015 Kia Sorento. Recently, one of my headlights failed. Upon attempting a routine bulb replacement, I discovered a critical hardware defect: the bulb socket is physically seized. It cannot be rotated or removed by any standard manual force. This is not a simple wear-and-tear issue; it is a mechanical seizure of a component that must remain accessible for safety maintenance. 2. Kia’s Refusal of Technical Guidance: To resolve this without damaging the entire assembly, I contacted Kia America (Case #[XXX]) specifically requesting technical instructions or any written explanations to safely disengage the seized unit. Despite multiple attempts via phone and email, Kia explicitly refused to provide any technical guidance, flatly stating they are "not technically trained" or authorized to share such information. 3. Obstruction of "Right to Repair" & Safety Risk: I firmly believe that a vehicle owner has a fundamental "Right to Repair," especially for essential safety components like headlights. By withholding basic maintenance instructions, Kia is intentionally obstructing my ability to maintain a street-legal, safe vehicle. Driving with a non-functional headlight is a Critical Safety Hazard that severely impairs visibility and creates an immediate risk of fatal accidents—yet Kia has chosen to leave me in this dangerous situation. 4. Exploitative Business Practice & Systemic Failure: This appears to be a deliberate and Exploitative Business Practice. By failing to provide a manual and refusing technical support for a defective, seized part, Kia is effectively forcing consumers into a "forced monopoly" where we must pay for expensive replacements at authorized dealerships for what should be a low-cost, simple bulb change. 5. Request for Investigation: I request that the NHTSA initiate a formal investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

- I was driving down 55 mph. on dark, busy highway in Sarasota, Florida (Fruitville Rd.) at approximately 6:15 a.m. on Friday, January 23, 2025. - Suddenly, without warning, the sidewall of the rear passenger side tire completely blew out in a perfect circle around the entire outside of edge. - The tire is currently available for inspection. - The Goodyear dealer claims that the blowout was caused due to underinflation. However, the tread pattern of the tire shows no signs of underinflation. - Since this is my wife's car, I check the tire pressure every other Sunday evening knowing that she'll be driving it to work the next day. - Had there been heavier traffic, the blow out could have caused a major accident if someone was following closely behind me. - The car's TPMS sensors weren't illuminated to indicate there was any low tire pressure.

Yes there was a recall in a module control panel which still is messed up. It’s been replaced a couple x. Also the dim lights since I bought the car have a very low light were you can hardly see at night. And this SUV drinks gas on long/short trips. I’ve taken it in several times but they keep saying nothing’s wrong and I know there is I have driven my boyfriend vehicle which is a V6 and went the same exact distance and didn’t have to get any fuel until I was about half way back. Something has to give. I love my Kia as I have owned 2. But something is really wrong. Please help. Thanks

The low beam headlights do not illuminate the highway sufficiently to drive safely. I lowered the aim of my high beam to be able to drive at night and not blind approaching drivers. This is unacceptable for a modern vehicle to be permitted to be sold in this condition.

I was driving down a very busy road and with no warning my car lost power. It would turn over but not start back up. I was stuck in the middle of a busy road way causing traffic’s to back up. I had to call the police to sit behind me so I wouldn’t get hit from behind.

My vehicle has a slow speed pick up and I’m getting code p0018 and has very rough idling !
