KIA Complaints

I was operating a 2024 Kia Telluride and was fully stopped in traffic when my vehicle was rear-ended by another vehicle. Immediately after the impact, my vehicle experienced apparent unintended forward propulsion/movement despite my braking attempts. Following the collision, the vehicle continued moving/driving forward for approximately 20 seconds and did not respond normally to brake input. The behavior created a loss-of-control situation and significantly increased the risk of secondary collisions, injury to vehicle occupants, nearby motorists, and pedestrians. I was unable to immediately stop the vehicle despite attempting to do so. The exact failed component has not yet been definitively identified; however, the incident appears potentially related to malfunction or unintended operation of one or more of the following systems: * drivetrain/transmission engagement, * electronic throttle control, * braking system, * powertrain control module, * or Advanced Driver Assistance Systems (ADAS). The vehicle should be inspected for: * Event Data Recorder (EDR) data, * diagnostic trouble codes, * throttle/brake command activity, * drivetrain engagement data, * and post-collision electronic system behavior. The vehicle is available for inspection upon request. At this time, the issue has not yet been reproduced intentionally. The vehicle has not yet been fully evaluated or confirmed by a Kia dealer or independent repair facility for the specific unintended movement condition. The vehicle is expected to undergo inspection and diagnostic review as soon as the Progressive adjuster issues the acceptance/approval letter. The vehicle will then be observed by insurance representatives, and collision repair personnel, as part of the accident and claim process. Prior to the collision and unintended movement event, there were no known warning lamps, dashboard alerts, or noticeable drivability symptoms indicating

Driver awareness warning goes off frequently. There is no way to desensitize it. As a result warnings are ignored. Dealer and manufacturer says there is not way to prevent this issue.

While accelerating onto the highway in my 2016 Kia Optima 2.4L, the vehicle suddenly lost all engine power without warning. The vehicle would no longer accelerate and I was forced to coast and brake to safety. Immediately after the engine shut off, the check engine light, oil light, and battery light illuminated on the dashboard. After the incident, the vehicle would not restart or crank at all. The electrical systems, dashboard lights, and chimes still function normally, and the battery is new. The vehicle had proper oil level at the time of failure. No warning signs were present prior to the sudden loss of power. This failure created a serious safety hazard because it occurred during highway acceleration and left the vehicle unable to maintain speed or move out of traffic safely. Based on the symptoms and sudden engine shutdown, I am concerned this may be related to the known Theta II engine issues associated with Kia Optima vehicles.

Kia has common problems on the airbags even tho my air bags is good but I want to still check it

The sunroof exploded. Nothing hit it, there was nothing wrong with it previously and it was not being used at the time it exploded. We were driving and it exploded with a loud boom.

At 116 miles, the engine blew and I was informed it would need to be replaced. I purchased a used engine from the same year of vehicle because Kia said it would not be covered since the vehicle had passed the 100,000 mile mark. I spend over $5,000 to get this engine and have it installed by a licensed mechanic. This second engine has now also blown leaving me without a vehicle as a single mom with a child who has a medical disability. Kia does not have a recall on this engine, which is clearly faulty. There is no way for me to come up with the funds to replace this engine for a second time and is something that should not even have to have to be figured out. I have been in touch with multiple mechanics who say the only way to repair is to replace as it would cost way more to try to rebuild. Kia should stand behind this as they know it is an issue.

Vehicle has excessive oil consumption defect acknowledged in Kia TSB ENG222. Repeated catalytic converter failures indicate potential overheating risk similar to 2019 Gamma engine recall for fire hazard. Engine burning oil creates risk of critically low oil levels leading to engine failure/stalling while driving. Multiple emission system failures (oil consumption, catalytic converter) suggest unsafe vehicle condition. Vehicle failed Kia’s own oil consumption tests in December 2023 and March 2024. Kia dealership recommended engine replacement per TSB ENG222 in March 2024. Kia denied coverage citing “second owner, out of warranty” despite defect clearly existing at time of purchase and being acknowledged in their TSB. Vehicle now showing catalytic converter failure code again (14-month-old converter failing). Kia refuses to remedy despite documented defect.

Leaking windshield. Water dripping into cabin. Headliner soaked with water. Windshield possibly not sealed or adhered properly. (Similarly to NHTSA Campaign 22V158000 and Kia Recall SC232 for the Kia Cadenza)

I am filing a safety complaint regarding my 2023 Kia Sportage Hybrid. The vehicle developed a “Check Hybrid System” warning and was diagnosed by a Kia dealership as having a failure involving the high-voltage hybrid system, specifically the MCU (Motor Control Unit). The dealership informed me that the vehicle may be unsafe to drive due to the possibility of fire risk associated with the high-voltage system. I was told technicians had to use specialized protective equipment while diagnosing the issue and that the diagnosis process took nearly a week. The repair estimate was approximately $5,000, in addition to approximately $750 charged for diagnostics alone. The vehicle is reportedly out of warranty due to mileage, even though this appears to involve a major hybrid system component and a potential safety defect. This concerns me because: - the vehicle is a relatively new 2023 model, - the failure involves the high-voltage hybrid system, - Kia advised the vehicle may catch fire, - and independent mechanics generally cannot service or repair these proprietary hybrid components. I believe this may represent a broader safety issue or defect involving the hybrid system or MCU components in Kia hybrid vehicles. I am requesting that this matter be investigated for possible safety defects, recall eligibility, or manufacturer responsibility.

A major drivetrain service and repair was completed by an authorized manufacturer dealership. After picking up the vehicle, an unusual front-end/steering noise was immediately reported to the staff. Over just 390 miles of driving, the symptom worsened. A subsequent formal inspection by a separate, independent authorized service center confirmed the root cause of the safety failure: the primary axle nut had been left completely unstaked during the initial drivetrain assembly, rendering the vehicle entirely unsafe to operate. The vehicle was grounded to prevent an accident. Because the mandatory safety protocol of staking the axle nut was omitted, the critical fastening hardware was allowed to back off under normal driving conditions. This component failure directly compromised the structural integrity of the front drivetrain, steering knuckle, and wheel hub assembly. Had the vehicle continued to be driven, the omission presented an imminent risk of complete mechanical separation, which could cause a wheel assembly to detach or lock up while in motion at high speeds, putting the safety of the occupants and other motorists at extreme risk. The vehicle remains grounded and is available for inspection. The safety-critical assembly failure has been fully documented by the inspecting service center via technical video (available upon request) and photographic evidence. The manufacturer has been notified of the dealer workmanship defect but has failed to authorize corrective action or safe transport of the vehicle to a certified facility for remediation.
