KIA Complaints

The contact owns a 2016 Kia Optima. The contact stated that while operating the vehicle a knocking and rattling noise coming from the engine and the check engine light had remained illuminated. The vehicle was towed to the local dealer who informed that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 150,000.

Car seat lower hip straps frayed on both sides. Had we been in an accident I have no doubt the strap would have ripped. I have 3 personal friends who checked their same Evenflo Revolve 350 car seat to find fraying in the exact same spots. And dozens of posts online with pictures showing the exact issues as well. The integrity of that straps in these seats are obviously compromised for so many people to be having them fray in the exact location. Evenflo is telling us all it's due to "external factors such as a mouse" but it would not all be the same car seat it happens to, in the exact same place on the seat, to people who drive their vehicles daily and have no other wings of rodents in their vehicle or issues with the other car seats installed in the vehicle.Baby/children's car seat safety is SO important and the strength of these straps needs investigated before someone is in a crash and their child's harness rips! Uploading my own personal photos-but I have many screenshots of pictures and posts from others having the same issue that I can provide upon request.

While driving car began to decelerate and the dash lit up with a number of ABS/Brake system failure symbols. I was on the highway traveling at abt 70 mph when the issue happened. Got car to coast off hwy onto an upward sloping exit. Stopped at a light. Turned off and back on and was able to gain minor speed got approx three blocks to a gas station. Pulled off and tried restarts. The screen stated there was an update pending, but it could not complete it because the Electronic Brake System failed. I tried triggering a brake reset but it didn’t work. Car was towed back to Dealership. Two days later the Dealership mechanic confirmed the issue was a failed Electronic Brake which must be replaced. Car has now been with Dealer for 10 days. Dealer stated the EBS was on back order and they do not have a timeline for the parts to come in. They’ve provided me a rental from their fleet which they are covering in full. Hoping this is resolved soon.

On may 20 2026 car died out multiple times when driving but would start back up. Today may 21 2026 car was lacking power and engine making noise while driving. Then the check engine light came on also the oil light flashed then turned off. Checked the code it said p00114. Then checked oil it was about 1 1/2 quart low after we did complete oil change a month ago. I then found this engine has the same exact problems we are experiencing and have a recall to replace engine, but when we enter our vin it doesn't show for our vehicle.

ICCU failure. Total and sudden loss of power. No acceleration. "Limp mode" activated for 5 miles before total shut down.

The vehicle just shut down as I exited. The power and gas pressure decreased. Pulled over to see if my hybrid battery was defective or drained. It wasn’t. A notification popped up and said “Hybrid Control System or Low Voltage DC/DC Converter, Contact dealer for service. Finally got it towed to Kia of Valencia the next day and they said it was “Hydraulic Clutch Actuator” and they want charge me $2200 to fix it. But looking up the part, it says there’s a recall for that exact problem.

Bought the car 8 months ago from a Kia dealer. It is now pulling the same engine codes, of the infamous recalled Kia engines. After having diagnostics done at a different Kia then I had bought and had oil changed. They told me the engine and turbo was full of metal shavings and the rods were bad. I pad $10,900 for the car $15,000 to fix, they knowingly sold me a totaled car. I’m sure records reflect they took that car as a trade I knowing the engine was bad (they never checked the oil?). There were 90,000 forte sold in the US, best estimate I could find on the gt line was 4-5 thousand. All GT models do not have the turbo engine. So safe to assume that number is way lower. They know this is a manufacturing defect, and this model engine wasn’t recalled because the numbers aren’t not there. I’m sure these 2,500 or less turbo engines were manufactured in the same facility, same workers and process as the other 2020 forte recalls. The car is smoking and I’m being told “it’s ok to drive unless the engine light is flashing” which I’ll assume is before it catches fire, so I have to worry about that while not being under recall? This is a kid, who could catch on fire, would like to not go there

I am submitting a vehicle safety and certification concern regarding a 2023 Kia Sorento Hybrid that was marketed and offered for sale as a Kia Certified Pre-Owned (CPO) vehicle by Shawnee Mission Kia, 7951 Shawnee Mission Pkwy, Mission, KS 66202. On [XXX], during an in-person inspection of the vehicle prior to purchase, I observed conditions inconsistent with expected Certified Pre-Owned inspection and preparation standards, including inverter coolant below the minimum level, engine oil materially above the normal operating range, and deteriorated windshield wiper condition. A third-party witness was present during the inspection. Because the vehicle was being represented as Certified Pre-Owned, I requested the vehicle’s CPO inspection checklist and supporting inspection documentation from dealership personnel. The requested documentation was not provided despite multiple follow-up requests. Subsequent written communications from dealership management acknowledged failures in dealership standards and handling related to the matter. After a formal complaint was submitted to the dealership’s corporate parent, the dealership’s General Manager responded in writing that an internal review had been initiated concerning CPO preparation and documentation practices. The requested inspection and service documentation were still not produced. The dealership later confirmed in writing that the vehicle “has since sold.” I am submitting this complaint because the vehicle was represented to consumers as Certified Pre-Owned despite observed maintenance and inspection concerns affecting vehicle condition and safety-related systems, while supporting certification documentation was not produced upon request.

On the highway, not reaching speed at expected RPM, try increasing power and RPM stops climbing at 3500, and speed decreases suddenly, car starts bucking, check engine light flashing. I pull over, stop, and keep going after several minutes idling with no apparent issue continuing. I take the car to get a computer check of the engine light code, P0420 for catalytic converter efficiency. Take car to dealer, they diagnose the converter as being both melted and clogged, quote me $4200 to replace with OEM part. Go to get second opinion at another service center, they confirm converter diagnosis and additionally diagnose cause as relating to outdated ECU software causing converter overheating, something which was an active recall for Kia Soul vehicles from MY 2012-2016, but only the 1.6L models. My vehicle is a 2.0L model with the exact same issue causing the exact same result, but with no recall, the converter is shot and there is no accountability for replacing the damaged part and updating the faulty software, as well as for missing this faulty software in the first diagnostic.

The contact owns a 2020 Kia Soul. The contact received a notification of NHTSA Campaign Number: 21V259000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The local dealer was contacted; however, the vehicle was not diagnosed or repaired due to the lack of specialize mechanical technician. The manufacturer was made aware of the issue. The contact had not experienced a failure.
