While driving at highway speeds, the vehicle suddenly began bucking, lost power, and lost oil. The engine compartment immediately caught fire. The fire was entirely non-collision related and required immediate extinguishing. The incident was logged by the Washington State Patrol. The vehicle was towed and subsequently inspected by a certified Kia dealership. The Kia dealership technicians officially diagnosed the cause of the fire as a catastrophic internal engine failure, specifically noting in writing that they...

I am filing this complaint regarding a persistent low beam headlight failure on my 2016 Kia Rio that has not been resolved after a paid repair at an authorized Kia dealership. The low beam headlights on my vehicle stopped functioning. I brought the vehicle to Car Pros Kia in [[redacted]] for diagnosis and repair on [redacted].. The dealership diagnosed the issue as a faulty Body Control Module (BCM) and replaced it on [redacted]. The dealership released the car to me with a 25-point inspection reading that all...

exterior lights were functional. The repair did not fix the problem - my low beams remain non-functional. I returned the vehicle on May 15th, 2026 so they can remedy the repair. They released my vehicle to me a second time with no functioning low-beam headlights. On [redacted], the dealership is now quoting $3,205.01 for a wiring harness replacement as a third repair attempt, with no acknowledgment that the original diagnosis was incorrect. My vehicle was returned to me in an unsafe condition following a paid repair. Non-functional low beams are a safety hazard, particularly for nighttime driving. I am aware that Kia has a documented history of headlamp low beam connector wiring harness failures across multiple models, including extended warranty coverage and TSB ELE179 issued for similar issues in other Kia vehicles. I am requesting this complaint be added to the record for the 2016 Kia Rio. If other owners are experiencing similar issues, I believe this warrants investigation.

I am filing a complaint regarding repeated failures of the LED tail light assemblies on my 2016 Kia Rio. This vehicle uses combination tail lights that include both standard bulbs and integrated LED brake lights. The LED portion has failed multiple times over the life of the vehicle. I am now experiencing failure again, requiring replacement of multiple tail light assemblies. Each assembly costs approximately $400, and my vehicle requires four total units. This results in a significant repair cost for what should...

be a long-lasting component. LED lighting is widely expected to last far longer than traditional bulbs, and repeated failure raises concerns about product reliability and safety. The failure is intermittent and occurs at the brake light function. At times, the brake light does not illuminate unless the connector is physically manipulated. This creates a serious safety hazard, as following drivers may not be properly alerted when braking. This is not normal wear and tear. Brake lights are a critical safety system, and failure of sealed LED assemblies - especially more than once - suggests a design or manufacturing defect. I am requesting that this issue be reviewed for potential defect investigation, as other owners may be experiencing similar failures with these LED tail light systems. Vehicle Information: * Make: Kia * Model: Rio * Year: 2016 * Trim: SX * Component: Rear Tail Light / Brake Light (LED combo Assembly) I contacted Kia Customer Care regarding this issue and was advised to take the vehicle to a dealership and pay for a diagnostic inspection, with no guarantee that any repair would be covered. Given the repeated nature of this failure, the high cost of the assemblies, and the serious safety concerns for drivers, passengers and others on the road, this response is concerning. Thank you for your attention to this safety concern.

My car is experiencing excessive oil consumption. Upon inspection, it was determined that the issue lies with my catalytic converter. I have discovered that this problem has been reported in other Kia vehicles. The information I found suggests that the oil I am using is being bypassed by the catalytic converter, which indicates a potential issue with the Kia car's design. Engine light won't go off

My car is consuming a lot of oil and I have to add it on a weekly basis. The catalytic converter has already been replace once and is on the verge of having to be replaced again because of this issue. I just bought the vehicle last year. I see that there was a previous campaign with this same issue. See campaign NHTSA ID: 23V-652000. I am wondering why my vehicle was not part of it. Please advise next steps to remedy this safety issue on the 2018 KIA Rio models.

This vehicle is burning oil at an alarming rate: at least 1 quart per tank of gas, approximately 340 miles. No oil light comes on in the dash, even if the engine gets ran to dry. Kia accepts this and claims the vehicle is fine. Even with extended warranty coverage, I'm on month 8 now of trying to get this car fixed with Kia shops and now the catalytic converter is failing. Finally the car has displayed its first check engine code.

Complete engine lockup during operation at speed which caused steering and braking to be greatly hampered. How was your safety or the safety of others put at risk?

dealer or independent service center? Yes confirmed by an independent service center which told me it was either a cylinder rod or a lower engine bearing failure. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the manufacture KIA has a recall on other models in this year range but not the RIO. The other models have a similar engine failure caused by a faulty cylinder rod bearing. The RIO has never been added to this recall list, but it should be because it looks like the engine issues are also on this model in the same time frame. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, they only came on when the engine failed. Then every warning light appeared.
