2017 KIA SORENTO Complaints

The contact owned a 2017 Kia Sorento. The contact stated that while her husband was driving at an undisclosed speed, the vehicle hesitated to accelerate as needed. No warning light was illuminated. The contact's husband noticed a cloud of smoke in the rearview mirror, but the contact stated that the smoke was coming from the engine compartment. The contact's husband pulled over, and she, her husband, and daughter all exited the vehicle safely. Before the vehicle was engulfed in flames, the contact checked underneath the hood and discovered a piece of plastic on fire. The contact dialed 911, and police and firefighters arrived on the scene. The firefighters extinguished the fire. The contact was unaware whether a police or fire department report had been filed. The vehicle was towed to a tow yard, and the insurance company was made aware of the fire. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 117,000.

I am submitting a safety complaint regarding a **2017 Kia Sorento SXL** equipped with a **3.3L Lambda V6 engine**, which experienced **sudden and catastrophic engine failure** at approximately **137,000 miles**. Prior to failure, the vehicle exhibited **progressively worsening engine knocking and vibration**, indicating internal engine damage. Despite these warning signs, the failure occurred **abruptly while driving at highway speed**, resulting in a **sudden loss of power**. This incident created an **immediate safety hazard**, as I was traveling in active traffic and was forced to quickly maneuver to avoid surrounding vehicles. The unexpected loss of propulsion significantly increased the risk of a collision. The nature of the failure appears to be consistent with **internal engine component failure (such as connecting rod bearing failure)**, which is not typical for a properly maintained modern engine at this mileage. Importantly, my vehicle was manufactured in **November 2016**, placing it within an early production period for this engine. There is evidence from technical service information and consumer reports suggesting a **pattern of premature internal engine failures** in this engine family, particularly involving **rod bearing wear leading to catastrophic failure**. This raises concern that the issue may represent a **systemic defect** rather than normal wear and tear. I am concerned that other vehicles with this engine may experience similar failures **without sufficient warning**, potentially resulting in dangerous driving situations, especially at highway speeds. I am requesting that NHTSA: • Review this incident as a **potential safety-related defect** • Evaluate whether similar complaints exist involving the **3.3L Kia Lambda V6 engine** • Determine if an **investigation or recall** is warranted I am able to provide supporting documentation, including maintenance records, diagnostic findings, and repair estimates upon request.

The contact owns a 2017 Kia Sorento. The contact stated that while driving at 35 MPH, there was an abnormal knocking sound coming from the engine, and the vehicle lost automotive power. The oil pressure warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed with excessive oil consumption. An oil consumption test and combustion cleaning were performed; however, the failure persisted. The vehicle was taken to an independent mechanic, who confirmed the failure. The contact was advised to park the vehicle outside. The manufacturer was not notified of the failure. The failure mileage was 19,000.

On 3-21-26 I noticed the smell of gasoline after driving the vehicle. Upon inspection a noticeable fuel leak from the top of the fuel tank was evident from underneath the vehicle. Further inspection found fuel leakage at the fuel pump outlet line. After online research it was found that other vehicles of this type have hairline cracks on the fuel pump outlet causing fuel to spray out under pressure. Fuel pump assembly replacement has repaired the problem. No indication other than the smell of gasoline was noted at any time. This is a safety hazard that should be addressed ASAP. Part removed has only been inspected by me. Part is available. If I had not been diligent in addressing this problem the consequences could have been catastrophic. The fuel outlet on a high pressure pump should have never been allowed to be made of plastic. People's lives are at risk!

My 2017 Kia Sorento with approximately 175,000 miles experienced engine failure involving the engine and engine cooling system. The vehicle began showing symptoms including engine shudder, reduced acceleration, and a check engine light. These symptoms worsened and were diagnosed by a Kia dealership as internal engine damage, specifically a failure in cylinder 4. The dealership advised that the engine would require full replacement at an estimated cost of approximately $9,600. The failure creates a potential safety concern because the vehicle experiences loss of power during acceleration, which could increase the risk of an accident, especially when merging into traffic or driving at highway speeds. The issue was confirmed by an authorized Kia dealership, Community Kia, after performing diagnostic testing. The dealership completed multiple recall and service campaigns but determined that the engine was not eligible for replacement because a required diagnostic code associated with the knock sensor detection system did not appear. To my knowledge, there is no clear documentation confirming that the knock sensor detection system update was installed on the vehicle prior to the engine failure. If this system was not installed, the diagnostic code required to qualify for engine replacement may not have had the opportunity to trigger. Prior to the failure, the vehicle displayed warning symptoms including a check engine light, engine vibration, and loss of power. These symptoms appeared before the dealership inspection and diagnosis. This complaint is being submitted due to concern that the engine failure occurred despite known issues associated with this engine type, and that the failure creates a potential safety risk due to sudden loss of power while driving.

I own a 2017 Kia Sorento SX 3.3L V6 FWD with 68,000 miles and full documented service history. The HECU (Hydraulic Electronic Control Unit) failed, disabling the ABS and electronic stability control system. This is a known defect covered under Kia's settlement for some Sorento vehicles with identical HECU components. Despite the same defect occurring on my 2017 model, it was excluded from the settlement without justification. I paid out of pocket for the HECU replacement which cost $2645. This is a serious safety defect affecting the braking system. I am requesting NHTSA investigate whether the some additional 2017 Sorento models should be included in the existing settlement or subject to a separate recall given the identical nature of the defect across model years.

Engine caught on fire while driving down the hhighway in SC. Vehicle was towed to Fred Anderson KIA of Greer & has since been sold by them after sitting in their lot for almost 3 years. I was driving down the highway not knowing my car was on fire. I only pulled off at the exit because my son, who was in the car behind me, had called to tell me he needed to use the facilities at the next exit. I pulled up to a gas pump to top off my gas tank while we were there. It was not until then that I had smoke coming out from under the hood of my car. I opened the hood and the engine compartment was completely engulfed in flames. The fire department did come onsite to extinguish the fire but a bystander had already used an extinguisher and put it out. Insurance refused to pay due to the many issues with KIA vehicles and had reduced my insurance to only liability. There were no prior warnings of any issues with the car. We had been driving all night from Ohio to SC for a family wedding and we were still 3 hours away from our destination.

Driving up a small hill when you hear this knocking noise.The car got to the top of the hill and shuts off no engine no turn over spent 198 to get it towed then comes to find out that it is because the car had no oil from what the mechanic told me. The car had oil but apparently only this model has issues with not having oil and you have to do an oil change every 4 months rather than 10,000 miles and I just brought the car.

My airbag light is on after picking it up from a KIA dealership service and they are refusing to correct the issue that was caused by the dealership. I escalated the issue to KIA America and filled a formal case#25916418 on 2/26/2026. On 3/4/206 Tori at Kia Customer service informed me that it will not be covered because the dealership claims its a pre-existing issue. The dealership has failed to provide proof that that is true. Attached are: -The dealership’s diagnostic report -All text communications with the service advisor -Also have Video documentation of misaligned steering wheel I was unable to attach. Prior to dealership service, my vehicle was evaluated for approximately one week at a reputable independent repair facility for a cracked head gasket. At no time were there airbag warnings, steering issues, or safety system concerns. The vehicle was driven directly from the independent shop to the dealership where they preformed a warranty service. Upon pickup, I immediately observed: - Misaligned steering wheel - Illuminated airbag warning light - Coolant system air bubble (later corrected per dealership) The steering misalignment indicates the steering system was disturbed during repair. The airbag warning light appeared immediately afterward. The dealership’s report references “history” fault codes, but provides no proof the warning light was active prior to service. History codes can result from battery disconnection or electrical interruption during major repairs and do not establish a pre-existing defect. Given that: - The airbag system functioned properly before service - The steering wheel was returned misaligned - The airbag light appeared immediately after repair - There is no documentation proving a prior active fault I am concerned a critical safety system has been compromised. An active airbag warning indicates the system may not function in a collision. I am requesting that KIA fix this at no charge to me due to the reasons listed above.

On [XXX] at [XXX] my vehicle caught fire while it was driving on [XXX] in New Jersey. The vehicle had approximately 120,000 miles at the time. The fire appeared to start under the vehicle on the driver side. Prior to the fire, there was no issues or lights on the dash and nothing appeared while driving. The fire resulted in my whole car being totaled and towed away to a yard. I am concerned this fire may have been caused by a mechanical or electrical defect and poses a serious safety risk. I am requesting that this incident be reviewed and investigated for potential safety defects or recall.
