2014 Kia Rio Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Everything below is an owner-reported complaint submitted to NHTSA about the 2014 Kia Rio, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.

Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

I am filing this complaint regarding Kia America's arbitrary denial of coverage for a suspected connecting-rod-bearing failure in my 2014 Kia Rio (85,000 miles). The vehicle exhibits classic symptoms of the Gamma 1.6L GDI defect: excessive oil consumption (bone-dry after ~1,200 miles post-January 2026 shop oil change), flashing CEL, and loud rod knock after oil starvation. Kia corporate denied all extended warranty/campaign relief on 03/18/2025, stating the powertrain warranty expired in 2019 and "no campaigns" apply. This is inconsistent and deceptive: -U.S. Litigation: Early complaints and law-firm summaries in In re: Hyundai and Kia Engine Litigation II (C.D. Cal., 8:18-cv-02223) and related MDL explicitly referenced 2012–2019 Kia Rios with 1.6L Gamma GDI for the exact defect (oil burn → bearing failure → seizure/fire risk). However, Kia negotiated to exclude Rios from the final E2 Class Vehicles list (see kiaengineclasssettlement.com FAQ #6), limiting relief to Souls and select others despite the identical engine family. -Canadian Precedent: The McKenzie Lake/Strosberg class action explicitly includes 2012–2017 Kia Rios with Gamma 1.6 GDI for the same issues, providing inspections/repairs—proving the defect transcends model badging. -Safety & Consumer Impact: This selective denial violates Magnuson-Moss (unreasonable warranty conditions) and constitutes deceptive trade practices, as Kia advertised these engines as reliable while knowing the failure mode. I request: immediate investigation, compelled goodwill repair (or full engine replacement), and documentation of how Kia limited Rio coverage in settlement negotiations. Attached are all supporting records.

NHTSA ID 11725736 · filed Mar 20, 2026

I tried to get the parts fixed from the recall. However, when I tried to get it serviced I was adviced that the parts would take a few weeks to arrive. With an appending move to Helena, Mt from Lambertville, Mi they informed me that they would not be able to fix the recall issues. There is no KIA dealership within a reasonable distance from my current location. I am having issues with the dealership towing the rio without charging me the amount of $1300. The engine had completely stopped. I towed the car from Michigan to Montana with a Uhaul because of the recall issues.

The contact owned a 2014 Kia Rio. The contact stated that the vehicle was taken to a dealer where it was serviced under NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic). After the recall remedy was completed, the dealer provided documentation indicating that engine rods #3 and #4 were failing and could soon cause the engine to explode if not immediately repaired. Approximately 2 weeks later while the daughter was driving at approximately 70 MPH, the vehicle began to decelerate and emit smoke from underneath the hood. The driver was able to coast to the side of the road and safely exit the vehicle as it caught on fire. The fire department arrived on the scene and extinguished the fire. A police report was filed and no injuries were reported. The vehicle was towed and deemed totaled since the fire consumed it. A dealer was contacted. The manufacturer was made aware of the failure and opened a case. The failure mileage was 133,223.

the car has 93000 miles and it started making a knocking noise from the engine. I brought the car to a mechanic and told me the engine needs replace because the connecting rod was broken that there have been recalls for KIA's for this problem. I went to the KIA dealer for fix under warranty but they declined for lack of maintenance due to my first oil change was to long I did not retain my receipts. than i researched to find out the government/this sight is investigating Hyundai-KIA for this problem , the RIO was not on the original recall the case has been reopened in December to add the RIO so thats why I am here adding my car to the list.

report

From owner reports, verbatim

I WAS DRIVING 35 MPH ON A SIX LANE COMMERCIAL ROAD (THREE LANES IN EACH DIRECTION) WHEN THE VEHICLE SUDDENLY DECELERATED TO BELOW 20 MPH. THE CARS AROUND ME HAD TO SWERVE TO AVOID HITTING ME, AND I HAD TO TURN ON THE HAZARD LIGHTS TO WARN THE SURROUNDING VEHICLES. I TRIED PRESSING ON THE GAS SEVERAL TIMES, BUT THE SPEED WOULD NOT GO ABOVE 20 MPH. HOWEVER, THE RPMS WERE GOING ABOVE THE RED LINE (ABOVE 6,000) AND THE ENGINE WAS REVVING VERY LOUD. THE SPEED OF THE VEHICLE DID NOT GO ABOVE 20 MPH FOR THE NEXT FIFTEEN MINUTES OF DRIVING. I SLOWLY MADE MY WAY TO A SAFE PLACE TO STOP THE CAR AND PULLED OVER. I TURNED OFF THE CAR AND WAITED FOR SEVERAL MINUTES. I TURNED THE CAR BACK ON AGAIN AND THE SPEED CONTROL RETURNED TO NORMAL. HOWEVER, I AM NO LONGER COMFORTABLE DRIVING THE CAR, AS THE SUDDEN DECELERATION MAY OCCUR AGAIN. MARYLAND LAW REQUIRES THAT A VEHICLE ON THE HIGHWAY MUST HAVE A SPEED CAPABILITY THAT EXCEEDS THE SPEED LIMIT BY 5 MPH. THE SUDDEN DECELERATION AND INABILITY OF THE KIA RIO TO SPEED UP AGAIN MEANS THIS VEHICLE HAS A DEFECT THAT IS IN VIOLATION ON MARYLAND LAW. THE SUDDEN DECELERATION OF THE VEHICLE IN FAST MOVING TRAFFIC PUT MY LIFE IN DANGER, AND I'M FILING THIS REPORT SO A PUBLIC RECORD EXISTS THAT THIS PROBLEM HAS OCCURRED WITH A KIA RIO (4S) 2014 MODEL.
