Top problems in owners’ words

Engine
387 reports2 crashes17 fires
“Yesterday our car was making a knocking noise. It lost power temporarily. Upon pressing the gas pedal to the floor we were able to get up to 30 mph. We made it to a repair shop. They looked at it today. The Dip stick showed no oil. The did an oil change and it was down 3 quarts of oil. We just had the oil changed 3 months ago on June 20. No check engine light came on. No warning at all . We were driving on a road with no shoulder, so this was dangerous if the engine were to fail before we got to repair shop. They said we need a new engine and it will cost just under $10,000. It seems that many people are having this exact same problem.”
Exterior lighting
125 reports1 crash
“My high beams and low beams are starting to shut off randomly while driving. They are burning out weekly and having to be replaced. 1 of my tail lights is doing the same exact thing. I replace it. It works for a couple weeks and then goes out. When the headlights shut off my dash shows that i am trying to turn my headlights from auto to another setting, which is not the case. It has happened at night multiple times and that poses a danger because i cant see the road and people cant see my car. I have not had it looked at yet. I do see multiple complaints online for multiple different kia models and years. There is no recall and i do not see a TSB. Just curious with so many issues seen online why anything has not be accomplished or a recall available.”
Electrical system
97 reports5 fires
“The contact owns a 2017 Kia Sorento. The contact stated that while the vehicle was stopped and idling, the engine oil warning light illuminated, and the Apple CarPlay, radio, and HVAC system became inoperable. The vehicle was taken to the dealer, and the oil pressure switch was replaced under warranty. The dealer determined that the electrical system had failed due to the oil pressure switch leaking oil onto the wiring harness, and that the wiring harness needed to be replaced. The manufacturer was notified of the failure by phone. The failure mileage was approximately 131,000.”
Steering
97 reports
“Vehicle steers with more resistance to the left but very loose and easy to the right. Dealership diagnosed that a new steering column is required. Kia also issued a new vehicle limited warranty extension on the motor driven power steering. I believe the warranty extension should apply; however, dealer says it does not apply. The warning light required for the extended warrant is not on in my vehicle but there is a clearly diagnosed issue with the electronic steering as indicated in the repair quote.”
Fuel/propulsion system
39 reports2 fires
“Fuel injectors become unseated randomly causing gas to be sprayed inside engine compartment. Issue can be seen upon request. This issue could cause a fire/explosion as fuel sprays out. The issue was repaired once by an Independent shop, then the issue reoccurred and has now reoccurred again. The issue fails randomly and fully with the symptom being the vehicle not wanting to start.”
Power train
37 reports1 crash1 fire
“2017 Kia Sorento 2.4L GDI engine seized due to connecting rod bearing failure confirmed by P1326 diagnostic code multiple times. Vehicle entered limp mode limiting RPMs to 1800-2000 exactly as described in PI1802 campaign. Engine subsequently fully seized. Battery tested 98% healthy ruling out electrical cause. Vehicle towed to [XXX] Kia Avon Indiana. Kia Techline and Consumer Affairs denied PI1802 lifetime warranty claim citing used vehicle reconditioning despite PI1802 explicitly stating coverage applies to both new AND used vehicle owners per official Kia corporate document dated XXX. Consumer Affairs appeal case XXX opened but Kia states no further appeals possible. Kia is wrongfully denying lifetime warranty coverage guaranteed under PI1802 Product Improvement Campaign.”
