The contact owns a 2022 Kia Rio. The contact stated that while stopped at a traffic light, the contact heard an abnormally loud bang and believed that the vehicle had been struck in the rear by an object. The contact opened the trunk and became aware that the trunk shocks had become detached from the latch. The contact was able to open and close the trunk lid, but the lid failed to remain open after being raised. The vehicle was taken to an independent mechanic, who advised the contact that the trunk latch spring had failed and needed to be replaced. The contact was advised that the spring and latch mechanism were on back order. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 69,000.
While attempting to raise the passenger side window slightly, the automatic window mechanism malfunctioned. Instead of stopping when lightly engaged, the window rolled all the way up and trapped my right wrist between the glass and the frame. When I pressed the window down button, the window continued to roll upward, increasing the pressure on my wrist. I was unable to release my hand on my own and had to call for assistance to pry my wrist free. This put my safety at risk by causing a crush injury to my wrist. The vehicleβs anti-pinch safety feature did not activate. The issue has not yet been reproduced or inspected by a dealer or manufacturer. No warning lights, messages, or other indicators were displayed prior to the incident. The component is available for inspection upon request.
The contact owns a 2022 Kia Rio. The contact stated that the rearview camera would intermittently turn on while driving at various speeds. The contact also stated that while in reverse(R), the camera would intermittently display a blank or distorted image. Recently, the contact stated that the rear-view camera had failed to operate as needed. The dealer was notified of the failure, and the contact was informed that the head unit would need to be replaced. The contact was also informed that the vehicle was out of warranty and was given an estimate for the repair. As a result of the camera failure, the contact stated that while backing out of a parking spot, she crashed into a parked vehicle located in her blind spot. No injuries were reported and a police report was not filed; however, the contact did state that she suffered mental anguish as a result of the incident. The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 72,000.
When my car is running it makes a knocking noise from engine I have taken it th the dealer they heard it but said they can figure out where it's coming from. The engine runs hotter than normal. The rods I think are the cause
When traveling 60 mph and slowing to try to stop, brake pedal went all the way to the floor and vehicle would not brake. Had to engage emergency brake to stop vehicle during normal operation on multiple occasions. Once while stopped at a red light, vehicle was completely stopped, then the brake pedal lowered to the floorboard and the vehicle started rolling forward. I had to turn the steering wheel and engage the emergency brake to avoid colliding with traffic. No dashboard lights came on, no warning lamps or messages. No other symptoms. I went to the Kia Dealership immediately. There was a hole in my front brake line and all of the fluid had leaked out. Vehicle was less than 2 years old, less than 100,000 miles on it.
The windshield wipers only work consistently on the last two settings. When you push the wiper gear down to the initial setting where you can adjust the speed with the dial, it struggles to move or doesnβt move at all. I can hear the wiper gear trying to lift the wipers, but nothing happens.
This is neither a failure nor a malfunction but on several occasions I have had the light switch turn off at night while driving. I can reach over and push a button to the left of the steering wheel under the ac/heat vent and in doing so my arm has rolled the headlight switch off. I have to hurry up and turn them back on. The switch should lock somewhat in place as to take a purposeful twist for it to turn. The headlight switch turns too easy and it could cause an accident at night.
Issue 1) Power steering wheel stopped working after practicing parking in preparation for a drivers test. Issue 2) Fuel indicator did not worked as expected, takes 3 to 5 min (in motion) to get the indicator in the right position. I took the vehicle to the dealership, it was scanned and according to them, no DTC was stored, I got videos when both issues came up.
A deer ran out in front of me. I hit it head on. My hood unlatched and flew up and the hinges cut into the very top of the fenders. I donβt think a hood is supposed to pop open like this.
Vehicle pulls hard to left since purchased. Had in shop 3 times, but problem still exists. It was aligned and rechecked. Tires were switched on the front (by another shop) and it still has issues of pulling. Dealership refuses to diagnose the trouble, except for the front end alignment and says they voided last repair order (because they did nothing). Took to another shop and they went through it completely, even test-driving it. Verfied a hard pull to the left. They were the shop that transferred front wheels to correct the problem. It helped somewhat, but still pulling. Now Dealership says it must be the tires and urges us to get help from them.
Back up camera sometimes flips sides, so that obstacles on the right side of the car are shown on the left side of the camera screen. Sometimes the camera doesn't work at all.
Steering Gear Assembly completely broke at 81,000 miles. My daughter was backing up in a busy street at 5pm and lost 100 percent of steering control. Lucking cars dodged her and she didnβt get hurt or worse.
Placed car in park got out to open a gate. Car took off forward even when shifter was in Park Position and almost ran a child over.
Center Console Display blank (screen black) upon startup unable to see cameras and backing up affected creating safety concern.
seatbelts in rear are inoperable/anti theft not working. Kia dealership told me that its not their issue about the anti theft. I have been told on 3 separate occasions that my seatbelts have been ordered but they havenβt!!!! No one is following up with me, when I call I get told βuntil they can get in contact with the dealership Kia the corporate company cannot do anythingβ have 2 kids Kia the dealership as well as the corporate company knows about this and no one is doing anything!! NO ONE CARES
At speeds over 20 miles per hours there is a βflappingβ noise that sounds like a bag or piece of paper that is blowing in the wind. Although I donβt know were the noise originates, I can hear it clearly from the driverβs side b-pillar. It is incredibly annoying and greatly diminishes what is otherwise a solid entry, level vehicle.
On 3/19/23, as I was driving on a dry, straight, two lane road at the posted speed of 40mph, the car began to try to steer into oncoming traffic. I had to exert moderate force to keep the car in my lane. This continued continuously for about 1/2 mile. No low tire pressure indicator lights were illuminated, however the lane assist icon was on and green, indicating normal operation. Just as I was going to turn down a side street to check the tires manually, the steering returned to normal. However, the lane assist icon was now white, and as I drove the remaining approximately 2 miles home, the icon would change from white to green every 20 seconds or so. The car now operates normally. We took the car to the dealer today to be checked and they reported they could not replicate the issue. Attached is their report.
The contol post for lights, turn signal, and high beams is too sensitive. To control the lights, you twist the top of lever. To turn on turn signals, you flip the lever up or down. To turn on brights, the lever goes forward. To turn of lights, the lever is pulled back. The issue..... If you have brights on, when you pull lever back to dim lights, the top automatically twists to shut off the headlights entirely. DANGEROUS DANGEROUS DANGEROUS. My husband doesn't have this problem, but he has longer fingers and his fingers hit the lever more at the base where nothing twists. I have shorter women's fingers and they can't reach all the way down the lever. I have since adjusted how I dim the brights by reacing under the lever, (close to steering column), to pull the lever back. This is very uncomfortable and tends to cause me to make the turn signal come on, which could cause its own traffic accident. My remedy would be to make the headlights twist in the opposite direction for on off, or make the switch for headlights have a little more resistance.
Having been complaining about a noise from under the front right tire, I was initially told it was a little piece of plastic and that got cut off. I was still hear the scraping and squealing and I kept check the from right tire because I thought that's where it was coming from. I mentioned this to every mechanic at kia and was told "that's just how 2021s sound". Finally after months of complaining the noise got louder and you could hear it was clearly something in steering. They schedules an appointment for Dec 7th on Mon Nov 28th. Said it was safe to drive when that night while working I was turning a corner, I heard a loud spring noise, the tire and wheel jerked. It was snowing, so the car slide, only sliding into the curb. The front right break seemed to be locked and when you turn the steering wheel makes even more noise. Haven't been told the issue, but I'm certain it is not safe and definitely shouldn't be on the streets until it's fixed.
I had driven my wife to her school about 5 miles and headed back to my work another 5 miles when i tried to accelerate pass car I lost almost all power barely making it up a slight hill I kept going trying to make it to my house barely going 10 miles an hour. I thought the transmission had let go cause while I had the gas peddle floored i went at best 10-15 miles an hour I eventually parked the car I knew it would never make it up another slight hill. It was rowed to a nearby dealer where they could find no problem telling me it was just some bad gas. This sounds like what I read about today with a couple of other models of Kia.

π Understanding This Data
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is β but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The KIA RIO has 319 complaints on record across 10 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The KIA RIO has 12 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 35 of the KIA RIO's 319 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions β a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Poor) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable β simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all KIA RIO vehicles on the road β not any specific car. Two KIA RIO vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage β NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The KIA RIO has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
