The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 23
Against the median year of the KIA RIO. 50 means typical for this

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 2017 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 2017 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.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 2023529276,225 units in Canada
Brakes
Issue: On certain vehicles, the brake hydraulic electronic control unit (HECU) could short circuit. Safety Risk: A short circuit could create a fire risk, even while the vehicle is parked and turned off. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to replace the fuse(s) for the HECU. Kia recommends that you should park your vehicle outdoors and away from other vehicles or structures until the recall repairs have been completed.
Recall 202347617,615 units in Canada
Structure
Issue: On certain vehicles, a part in the trunk release latch could fail. If this happens, the emergency trunk release located inside the trunk compartment may not work properly. This could prevent a person that is trapped inside the trunk from opening it. Safety Risk: If a person is closed inside the trunk compartment, they may not be able to get out. This could create a risk of injury. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to replace the trunk latch base subassembly.

ENGINE
I was driving my 2017 Kia Rio at approximately 70 mph when the vehicle began shaking violently. I heard a loud mechanical sound from the engine compartment that sounded like something broke loose and was being thrown around. I immediately began pulling over as smoke started entering the cabin. As soon as I stopped, the car erupted into a fast-moving, intense fire originating in the engine compartment. The fire spread so quickly that the front of the vehicle and the passenger cabin were completely destroyed before the fire department arrived. The Austin Fire Department responded (Incident Type: Engine 2f) and the Travis County Sheriff's Office also opened a case (Case #[Insert Your Sheriff Case Number]). Multiple bystanders also called 911 due to the severity of the fire. The vehicle had under 80,000 miles and was maintained with regular oil changes every 6 months. I believe this fire was caused by a known manufacturing defect related to the engine connecting rod bearings or the HECU electrical short, both of which are subjects of major Kia safety recalls/settlements. The vehicle is currently a total loss

My son and I were driving home from work on IH-35 and I noticed smoke coming from under my hood. Then within seconds, flames appeared moving quickly towards the windshield. I attempted to move to the shoulder and after doing so, I was unable to stop since the brakes were no longer working. I had to use the parking brake when it slowed down and then once stopped, my son and I jumped out of the vehicle and within 3-5 seconds, the entire car was overcome with fire which then exploded.

The engine of my Kia Rio 2017 is the system that is failing it is sudden with no warning and has been diagnosed by Kia themselves stating that the engine will seize. My safety is put at risk because the car may seize while in traffic causing difficulty steering and breaking. This problem was first confirmed by an independent shop called Accurate transmission (1040 s Joliet st, Aurora CO, 80013 or call 3033646254) and following that I took it to Kia for a diagnostic where they confirmed what Accurate transmission stated. This vehicle has not been inspected by anyone currently. There were no warning lamps previous to current issue. Warning lights appeared upon incident.

I took my KIA Rio to mechanic for knocking noise in engine. Mechanic said it's not the original engine and has been replaced. Nuts and bolts are rusted and some aren't even tightened or torqued correctly. I am the second owner of this car and could have been in an accident. This is very scary. There was no information about a different engine or anything else warning me about KIA or Hyundai cars. Please let others know that their safety is at stake buying these vehicles.

ELECTRICAL SYSTEM
This vehicle has electrical issues none stop. One day it randomly stalled out while still in motion and lost all power. No power at all. It was “repaired” and I had it for 2 weeks and it again lost all power while in motion. It put my life completely at risk as I had to pull over into a parking lot after losing all power turning in the middle of a very busy main intersection. Kia dealership said it was the main wiring harness at first and replaced that but then the second time said that the new harness was out again and needed replaced a second time because of a fuse that was causing too much power therefor blowing the wiring harness again? Now I am having engine and electrical issues months later. I had what appeared to be a need for a tune up. Which was done. It has continued to throw wrong codes and lights come and go on the dash all the time. I’ve gotten several tests done and I always get a code stating misfiring even when there is no light on the dash. The check engine light will come on for 2 weeks then randomly go off for 2 weeks. No matter what it will throw a code as misfiring in the 1&3 cylinders. Spark plugs, coils, air filter. everything has been replaced yet the light still comes and goes and it continues to throw the code. Car has been seen by the dealership multiple times
