KIA Complaints

On [XXX] my son was driving on the highway when the car suddenly shut off.. thank god he was able to safely get to the side of the road. Had it towed to my local mechanic who stated that the engine is seized up. The car is only 6 yrs old and well maintained. There were no prior problems or signs. Need a new engine.

Engine began jumping during driving and loss power. No dashboard illumination warning lights and the temperature gage showed normal operating temperature. Car was not accelerating properly. Had to maneuver carefully to prevent being ran over. Engine light illuminated showing misfire. Replaced ignition coil pack and spark plugs. Driving again, car stalled. No dashboard warning lights. No high temperature on gauge. Narrowly missed being hit by a semi as there was absolutely no warning and we were on an Interstate bypass ramp with nowhere to pull over!! Towed car to dealership for diagnosis. Results: engine blown, turbos gone, and the catalytic converter is holding oil. Dealer is stating this is not covered under the extended warranty from Kia as its not connector rod bearing issues and that the piston rings failed. However, they stated the turbos got "too hot" and they failed. The gauges have never shown that the car was running hot. I have a sworn statement from my mechanic stating this is absurd and a valiant attempt to not pay for what would be the second warranty replacement of my engine. The piston rings failed as a result of the connector rod bearing failure. The "too hot" temperature that damaged the turbos was likely caused by the same bearing issue. The heat from the bearings unseated the piston rings and allowed the engine to dump its oil causing the engine to fail. I highly recommend that you open an investigation into these issues. The car not accelerating and losing power at interstate speeds is a very serious and dangerous issue.

Dealer says recall sc211 doesn’t apply to this vehicle, however CEL is displaying (once again) with DTC “P0191 Fuel Rail Pressure Sensor Range/Performance”. Kia dealer has does minimal investigation/diagnosis with no resolution.

The contact owns a 2011 Kia Sorento. The contact stated while driving approximately 55 MPH, the vehicle started to lose motive power. The accelerator pedal was depressed; however, the vehicle failed to respond as intended. The contact stated that several unknown warning lights were illuminated before pulling off the roadway. The hood was opened and there was white smoke coming from the engine compartment. The contact stated that the smoke then dissipated. The vehicle was towed to a local mechanic. The mechanic diagnosed the vehicle and determined that the alternator and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 200,000.

We are experiencing problems consistent with the issues identified in recall SC336, which pertains to defective piston rings potentially leading to increased oil consumption and engine damage. Specifically, for an extended period of time we have encountered significant oil consumption, the check engine light turning on repeatedly, engine overheating, and abnormal temperature gauge readings. Additionally, our vehicle has stalled multiple times while driving, lost power, and exhibited jerky acceleration, along with strange noises from the engine. These stalling incidents, in particular, were extremely frightening and created unsafe conditions on the road for our traveling family. We previously contacted members of Kia’s corporate office in early April 2025 (we can forward email), but unfortunately, we initially never received a response from Kia with respect to our email. We brought our vehicle to Wesley Chapel Kia for the recall service on June 9th; however, no repairs were made. Our engine was not replaced. We were told our vehicle passed the vibration test, which we find insufficient. The check engine light returned shortly after the visit to address the recall. We are aware that Kia changed the procedure for the recall inspection after the initial recall was announced. We have read accounts online from other Kia owners whose vehicles originally failed the recall inspection and were due for engine replacement—only to pass under the new testing protocol. This shift in procedure was never explained to us during our recall appointment, and we have serious concerns about the effectiveness of the updated remedy program. The lack of transparency and the unresolved issues with our vehicle leave us deeply dissatisfied and looking for answers. We are seeking assistance in understanding what steps we can take to ensure the safety and reliability of our vehicle and to hold the manufacturer accountable for following through on their recall commitments.

The contact owned a 2016 Kia Forte. The contact stated that while decelerating due to traffic, the vehicle was struck in the rear end and pushed approximately a few feet, causing the vehicle's front end to crash into the rear of the vehicle in front. No warning lights illuminated. No air bags deployed. The contact stated that due to the impact of the crash, she had fallen unconscious. A police report was filed. The contact sought medical attention for bruises and head damage. The vehicle was towed to the local tow lot, where it remains, and was declared a total loss by the insurance provider. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 22V031000 (Airbags) however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was unknown.

Myself and many other 2025 Kia Sorrento hybrid owners have complaints of the lane keep assist system, causing the vehicle to wobble back-and-forth within the lane. Causing dizziness to drivers. Sometimes wobbling so much that it could cause an accident. Here is the link to the Reddit forum where other owners have complained of the same issue: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle started with oil issues took to dealer and the attempted to perform an oil consumption test however the vehicle would not pass the test as the oil would not last long enough for next test. Was advised I needed an engine, Kia refused to replace since it wouldn’t pass consumption test. I paid for engine replacement 1month later engine light comes on, again I return to Kia dealer they say engine needs replacement they replace supposedly through warranty. Drive for about 30 days and engine light comes on again takes to dealer and they say it’s the knock sensors code which is the same code that came up prior to engine replacement. The knock sensor was a recalled part that they replaced by them but now are refusing to replace even though they replaced it less then 12 months ago.

Vehicle burns oil, current mileage at 169k. User manual indicates 7500-10000 miles between changes, I am original owner. Dealership service set for 5k intervals since purchase and done on time. At 99k noticed noises from engine, light rattling but couldn't replicate and couldn't pinpoint at dealership service. At 112k noticed burning oil and rattling noises when accelerating from stop. Changed to 3k oil change intervals, began using premium fuel. 1quart of oil at 0-1000 miles from oil change (had a consumption test at dealership and confirmed "normal" at 112k), sub sequential mileage burns more than 1quart between 1k intervals, can easily burn through 4-5quarts between 3k oil changes. Oil smells slightly like gasoline closer to oil change time. Outside mechanic confirmed rattling as detonation. Concerns of oil not "burning" but mixing with fuel either through oil vapors getting through PCV valve and diluting fuel octane causing rattling. Knock sensor suppresses from causing engine damage, but still happens. Fuel may be getting into the oil, not sure how, but wouldn't explain detonation. No codes, no other issues. Only check engine light since rattling noticed at 99k was failing O2 bank 2 sensor which was replaced by licensed mechanic with OEM parts. The amount of additional oil maintenance and changes were not disclosed on expected maintenance costs sheet posted on vehicles, nor is it communicated in the users manual. Personal opinion is the additional maintenance between changes is unreasonable, and oil isn't "burning" but leaking into the combustion chamber.

HVAC is not working at all, not even blowing hot air. I've been told it could be a wiring issue or have to change my blower and resistor. KIA has told me they could not help because my car is over the 60,000 mile warranty. However, my car is 70,000 miles and about 4 years old. It has had other recall issues and just trying to be helped.
