When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2016 KIA RIO
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543,...
Recalls on the 2016 KIA RIO
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

EXTERIOR LIGHTING
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 [XXX] for diagnosis and repair on XXX.. The dealership diagnosed the issue as a faulty Body Control Module (BCM) and replaced it on XXX. 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 XXX, 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.

EXTERIOR LIGHTING
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

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.

STEERING
What component or system failed or malfunctioned, and is it available for inspection upon request? 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? The engine failed on a 4-lane highway in traffic which could have easily caused a high-speed accident since the car extremely decelerated and lost power steering and braking in order to get out of traffic. Has the problem been reproduced or confirmed by a 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.
