The vehicle was sent spinning after it hit the barrier; the vehicle was facing oncoming traffic once it came to a stop. The air bags did not deploy upon impact.

The front seats electrical adjustments do not work properly, I have had ir switch mid drive and stying to adjust them is a hassle. They do not work properly.

While driving on 7/6/2022, upon acceleration, the vehicle began jerking and applying the brakes as if it was trying to attempt to avoid a rear end collision. Moments after that incident, the instrument cluster displayed warning lights of the following: check forward safety system, traction control, front end collision avoidance, electronic parking brake, and auto hold all in an orange color followed by a check engine light shortly after. Safety was put at risk due to the vehicle suddenly and uncontrollably braking without any warning on prior indication. The vehicle has not been inspected by anyone yet, but is schedule for a dealer diagnostic on August 9th, 2022. Currently, this vehicle has 10,900 miles on the odometer.

In this car, when braking or using the adaptive cruise control, the car shakes a lot, making yo lose control of the vehicle.

The Wheels Guards fell off mid drive, another part that fell off was the underbody cover that is made out of cardboard. I know many Kia K5 owners who have had this problem. It fell off due to rain. Since it is made out of a cardboard like material, the rain makes it fall off while driving.

Can is going 4000rpm at 70 mph. Feels like no power, won't go over 80 mpg. To it the dealer but didn't do anything unless the check engine light is on. Can is 10 months old.

The windshield cracked and spread very quickly without any known reason. I made an appointment with the dealership and was told that they do not handle that situation and was dismissed without a proper check. Will be checked by an auto glass company soon. There was no indication of any failure/warning lamps. There were no prior chips in the windshield that were prone to further damage, no loud sounds and the crack appeared while the car was parked on my carport.

had the windshield replaced on March 14, 2022. i drove the car for approximatly for two weeks with no issues. i left my car parked while on vacation and took a cab to the airport. after i returned home from vacation and drove my car for the first time in almost two weeks i noticed the cracks on the windshield. one on the lower area of the passenger side and another that is on the driver side about mid ways. both have spread and since then there are two smaller ones starting. i have been constantly contacting the dealership who is giving me the run around. but on may 3 they are wanting to see the car windshield. the glass company the dealer uses has no warranty for their work. The cracks are inside the glass you cant feel them at all. i know the service guy wanted to know if i had a telluride i told him no i have the K5.

Horn went out? No explanation

The undercarriage of the vehicle fell as I was driving down the highway. Yes it is available upon request. My safety was put at risk because part of the undercarriage piece started to rip and go underneath my tire. The problem was inspected by a dealer. The component has not been inspected by anyone else. There were no warnings prior to this occurring.

The contact owns a 2021 Kia K5. The contact stated that while driving at various speeds, the Lane Assist feature would illuminate without other vehicles nearby. The contact also stated that the vehicle would independently switch lanes independently; causing the contact to forcefully adjust the steering wheel into the desired lane to prevent a potential crash. The contact manually disabled the features; however, the features independently reactivated. In addition, the defroster failed to operate as needed which obstructed her vision due to fog on the windshield. The vehicle was initially taken to a dealer, but the contact was offered no assistance. The contact then took the vehicle to Kia of Irvine (45 Oldfield Building B, Irvine, CA 92618) where two mechanics acknowledged the failure while test driving the vehicle. The contact was assured by the dealer that both safety features where disabled; however, within minutes of leaving the dealer; the features independently reactivated. The manufacturer was notified of the failure and the contact was given a case number. The vehicle had yet to be repaired. The failure mileage was 17,951. The consumer called to make an appt due to the check engine light illuminating and informed vehicle will not be repaired for a few weeks. In the meantime the gas smell is pouring through the vents.

The bumper is way to low so if you try going up a hill or if you park and there are stoppers, the bottom of the bumper scratches and rubs on the bottom causing it to pop off. You may not realize this until you are driving and it falls off

While on her way from work, my mother was involved in an accident in her 2021 Kia K5 LXS where she was rear ended at a high speed by a driver not paying attention to the road and she ended up hitting the car in front of her. During the accident NONE OF THE AIRBAGS DEVELOPED. My mother was hospitalized for a month and do to the SEVERITY OF HER MAJOR INJURIES (rib fractures, a closed fracture of her T7-T8 with loss of sensation and mobility of lower half of body) she passed away from “Effects Of Blunt Spinal And Rib Cage Trauma.” No recalls were noted for this particular model and year until March of 2023 which was way too late.

Took my car to the dealership on 12/20/21 because all of my sensors were going off so they installed a new harness and cleared all the sensors, I got my car back on 1/3/22. On 1/16/22 all my sensors came back on so I brought it back to the dealership on 1/19/22 and I got it back the next day and was told it was safe for me to commute to work (I got it back with the front panel off with exposed wires and no working airbags) and a few days later all the sensors were back on and as I’m driving home in the middle of the night from work my tire pressure sensor came on even tho I had air in my tires, my headlights turned off for seconds at a time, my speedometer kept dropping to 0 as I’m going 60 and my cruise control stopped working. Have pictures and videos of every issue every time

Vehicle engine shut off while driving down the highway. Traveling on 74 and while still in drive the engine abruptly shut off. Vehicle was started again and then it again shut off a couple miles down the road. When the vehicle was started a 3rd time it immediately went into limp mode. I was stuck on the side of the highway with vehicles going 70MPH around me. On my way to the dealership the car shut off multiple times potentially killing me multiple times. After 60 days at the dealership they said they fixed the problem. I drove the car 4 miles and it shut off on me on the highway again. I had a car almost crash into me along with trying to start the car and get off to a safe location. I still do not know what is going wrong with the vehicle but this could of killed me and others..... this needs to be addressed along with the fact they gave me the vehicle back just for it to do it again.

BRAND NEW VEHICLE PURCHUSED OFF SHOW ROOM FLOOR WITH 4 MILES ON IT. 3 MONTHS AFTER OWNERSHIP, WHEN PUSH TO START THE CAR. THE STEERING WHEEL WILL LOCK UP, UNABLE TO DRIVE AND A SYSTEMS CHECK WILL DISPLAY ON THE DASH. IT DOES NOT STOP, UNTIL YOU TURN THE CAR OFF AND ON SEVERAL TIMES, WITH NO SET AMOUNT OF TIMES UNTIL THE CAR IS DRIVABLE AGAIN. THE CAR HAS BEEN BROUGHT TO KIA SEVERAL TIMES FOR SERVICE, BUT THEY HAVE NEVER BEEN ABLE TO DETERMINE A REASON. A LEMON LAW WAS FILED AND COMPLETED IN 2022. THE CAR SINCE THEN HAS CONTINUED TO HAVE THE STEERING WHEEL LOCK UP RANDOMLY WHEN STARTING IT AND HAS EVEN PROGRESSED TO DOING IT WHILE DRIVING ON THE HIGHWAY!!! NO RECALL FROM KIA HAS BEEN ISSUED. THEY ARE JUST WAITING FOR SOMEONE TO DIE!

The contact owns a 2021 Kia K5. The contact stated that while her daughter was driving at 5-10 MPH and making a turn on a road with no lanes, the steering wheel inadvertently started shuddering and became rigid, causing the contact's daughter to lose control of the vehicle. The vehicle crashed into a construction dumpster. An unknown warning message illuminated. The air bags did not deploy. The contact's daughter did not sustain any injuries. A police report was not filed. The vehicle was towed to the contact's residence. Then, the vehicle was towed to the dealer who towed the vehicle to a collision center. The dealer informed the contact that the vehicle could not be repaired under NHTSA Campaign Number: 21V447000 (LANE DEPARTURE, STEERING) as the VIN was not included in the recall. The manufacturer was notified of the failure and a case was opened. The vehicle was not diagnosed or repaired. The approximate failure mileage was 11,700.

My vehicle is a 2021 Kia K5 GT (2.5L-T), mechanically identical to Hyundai Sonata N-Line (2.5L-T). My car has 24000 miles on it and I have replaced the rotors on my car five times now due to premature warping. KIA OEM rotors, R1 Concepts, Brakenetic Rotors, all have warped. This issue is discussed amongst GT and N-Line owners heavily in the forums stating how the OEM Brake system has some sort of issue that causes premature rotor warp. Some have even resorted to changing their brake system to a old model Cadillac CTS-V system because of how crap these brakes are. Again after less than 2 months with new rotors, they have warped yet again.

Since October these features have been on and off working when they want to. I don't know what is happening with the safety features but it needs to be fixed or a update is needed for all the safety features.

I was driving 35 mph with nobody in front of or behind me and the car slammed on automatic braking for no reason, stopping me in the middle of the road.

When filling up the gas tank on 3 separate occasions the station pump failed to cut off causing fuel to leak unto the surrounding surface. The Kia K 5 is leased vehicle that I entered into contract in July 2021. The car was used as a demo and I find it suspicious that the dealership wasn’t aware of the issue. The dealership is replacing the gas tank at no cost to me.

Sunroof exploded while driving. Only had the car 2 months.

This report is being filed as a duplicate to 11488885, as this issue occurred twice. Please see 11488885 for details, as issue was exactly the same. I have attached the dealership repair invoices for both incidents as I forgot to do so in 11488885.

My 2021 KIA K5 developed a chip after a small pebble hit the windshield. By the time I got home(an hour and a half later) the chip caused a crack across three quarters of the windshield. The dealer and KIA Corporate will not admit the problem even though there have been numerous complaints on the Telluride model and now several complaints documented on the new K5.

Purchased new Kia K5 LXS few months ago. Originally warning lights appeared on dashboard. At first windows would come down intermittently. Now my windows won't come down at all. My headlights flicker and turn off at night. Car sounds like it's powering down at times. Contacted dealership a number of times. Alerted dealership of problems and concerns via phone and during service. Met with indifference and treated like they hadn't talked to me regarding latest concerns. This shouldn't happen to any vehicle especially when purchased brand new.

VEHICLE WAS STOPPED A RED LIGHT ON A CITY STREET WHEN SUDDENLY CUT OFF. SMOKE BEGAN TO POUR OUT FROM UNDER THE HOOD. LESS THAN 1 MINUTE LATER THE VEHICLE WAS FULLY INVOLVED UNDER THE HOOD OF CAR. CAR WAS A TOTAL LOSS. VEHICLE HAD JUST BEEN DRIVEN APPROXIMATELY 25 MILES (ALL HIGHWAY) FROM HOME TOWARDS WORK WHEN INCIDENT OCCURRED.

WHILE I WAS DRIVING ON THE INTERSTATE, I HEARD AND ABNORMAL ABOUT OF NOISE COMING FROM THE ENGINE BAY AS WELL AS A SCRATCH WHILE I WAS DRIVING. THIS HAPPENED ON MARCH 26, 2021 AT 10PM. ON MARCH 29, 2022 I TOOK IT TO THE DEALER SHIP AND I WAS NOTIFIED THAT MY ENGINE COVER CAME OFF AND WAS THE CAUSE OF THE NOISE. THERE'S DAMAGE TO MY DRIVER SIDE FENDER, RUBBING TO THE WHEEL/TIRE AND MY FOG LIGHT HOUSING IS HANGING.

I WAS TRAVELING AT APPROXIMATELY 40-45 MPH, ANOTHER VEHICLE CROSSED IN MY PATH, AND I BROADSIDED HIS VEHICLE. I AM NOT SURE OF MY SPEED AT IMPACT. I WOULD GUESS 30 MPH. AIRBAGS DID NOT DEPLOY. THE REAR DRIVERS SIDE SEAT ALSO CAME UNLATCHED, FOLDING ITSELF DOWN. THERE WERE NO OTHER PASSENGERS IN THE VEHICLE.

I WAS TRAVELING 45 MPH IN MY 2021 K5 GT LINE WHEN AN OLDER TOYOTA CAMRY CROSSED MY PATH. I APPLIED BRAKES BUT THERE WAS NO AVOIDING THE COLLISION. I BROADSIDED THE CAMRY AT SOMEWHERE BETWEEN 30 AND 35 MPH. I SUSTAINED INJURIES TO BOTH KNEES, NECK AND BACK. AIR BAGS DID NOT DEPLOY. POLICE, WRECKER DRIVER AND BODY SHOP (IN THIER PREVIOUS EXPERIENCES) ALL SAY THEY ARE SURPRISED THE AIR BAGS WERE NOT TRIGGERED BEING THE FACT IT WAS A FRONTAL COLLISION. ANOTHER CONCERN IS THE FOLDING SEAT BEHIND THE DRIVER'S SIDE BROKE FREE OF THE LATCH AND FOLDED ITSELF DOWN. THAT SEAT HAS NEVER BEEN FOLDED DOWN OR EVEN SAT IN FOR THAT MATTER, SO I KNOW FOR A FACT IT WAS LATCHED. SAD TO SAY MY BEAUTIFUL BRAND NEW K5 THAT I HAVE HAD FOR 2 MONTHS NOW HAS CLOSE TO $13,000 DAMAGE. MOST IMPORTANTLY, I AM NOW SCARED TO DRIVE THIS THING. WHAT IF THIS HAPPENS AGAIN?

Does not always shift like it is supposed to
