Unknown...the car goes into limp mode suddenly...my battery was boiling an shot liquid out of it, prior to this my other battery leaked an the alternator was bad ....when this happens suddenly you have no steering, an if course the boiling battery may explode....I've had this car checked over several times since begining of January with everything checking out fine but this still happening

Came out of work to a cracked windshield. There was no crack in my windshield prior to this. The crack spans across half of the windshield requiring a full replacement which is going to come completely out of pocket for me because I had a $1000 deductible. Had I known this was such a common issue with this year make and model, I would’ve opted for the $0 glass deductible. As many others have reported and stated, this was never an issue I’ve had with any other vehicle I’ve owned. It is clearly a manufacturing defect and SHOULD be covered by Kia. I’ve had this car for 7 months.

The steering wheel became stiff all the sudden and became hard to turn. As well as all the warning lights came on when that happened such as Adaptive Cruise Control Automatic Emergency Braking Blind Spot Warning Forward Collision Warning Lane Departure Warning Lane Keeping Assistance Parking Collision Warning Rear Cross Traffic Warning. I was driving in the middle of the road when this happened and this could’ve caused a huge accident due to the fact that I couldn’t steer my car properly. No, the problem has not been resolved yet. It is in the dealership at the moment to be inspected. There was no problem prior to the other signs coming on besides low tire pressure. The appeared as I was driving on the road.

•I’m not sure what failed, the car was parked. And yes it’s available for inspection. •I had just parked the car coming from work and at the time. If I was in the car any longer than 5 more minutes it possibly could’ve been catastrophic. • All I know as of right now is that 5 days ago, it was escalated and I received a case number and a case manager 3 days ago. •The car has not been inspected •not that I’ve noticed, the engine light was on a week before the accident occurred, after getting off of work and the car system said to check my breaks. I had someone take me home since my car was undrivable. And the next morning I was going to have it towed but everything was working properly. The engine light was gone.

My kia Sorento shocks are really bad seems like it bounces Alot More than normal and heard a squeak coming from the shocks also hard to get the to turn when Im park and electric seems to glitch with bulbs going out faster and radio acting like it shorting out since the wiring was replaced it does this

Description of Incident: On February 9, 2026, at approximately 3:00 PM, I was driving my 2021 Kia Soul on Calvine Road and Winterberry in Elk Grove, CA. A vehicle suddenly merged into my path. I immediately attempted to apply the brakes, but the pedal failed to depress or engage normally. Despite the imminent collision, the Forward Collision-Avoidance Assist (FCA) failed to provide any alert, and the Automatic Emergency Braking (AEB) system did not activate. To avoid a high-speed, rear-end collision, I was forced to perform an emergency steering maneuver toward the curb and into roadside bushes to stop the vehicle. This maneuver resulted in severe mechanical failure, including a broken driver-side axle, damaged rims, and broken brake pads. The dealership (Elk Grove Kia) has provided an estimate of $9,461.67 for these repairs but has failed to explain why the primary safety systems and service brakes failed to function as designed during this emergency.

I bought a Kia 2020 from Long Lewis 3 days after i got it the check engine light come on, I called and told them, then around the 5th day black smut started covering the back of the suv, and i was smelling a burnt oi; and antifreeze smell, took it to a shop and they pulled the codes and one code was P045600 and another was P074100 then airbag codes, not even a month it started jerking they told me to bring it in so i did, he said they cleared the codes and was gonna fixed the evap, i asked about the torch converter and he said that must've been a code from the history but it wasn't, it did have a history of the code though, and i asked about the black smut on back of the vehicle he said nothing they can do about that and said fixing the evap may fix it, but sometimes it smells like it's on fire, and jerks

Started my car while I was out and heard a pop sound. Warning message appeared saying "check electrical vehicle system". I was able to drive but when getting onto the freeway, I started to lose acceleration and go into limp mode. I pulled over on the freeway and had to get car towed to dealership. Dealership service center confirmed that my ICCU part failed. The vehicle to my knowledge hasn't been viewed by anyone other than the dealership.

On December 27, 2025, at approximately 150,556 miles, my 2015 Kia Optima Hybrid experienced sudden engine knocking, power loss, and failure while driving at 65 mph on a highway. The vehicle dropped into limp mode and I had to pull off the highway. The car required towing to the dealership as it would not drive safely. Diagnostics revealed a knock sensor error (P1326 code) and failing connecting rod bearings via Bearing Clearance Test, consistent with the known Theta II engine defect (manufacturing debris causing oil starvation and premature bearing wear). This follows earlier symptoms: Intermittent 'Check Hybrid System' warnings in early December 2025 at 148,665 miles (dealership unable to reproduce, but historical codes noted). The Knock Sensor Detection System (KSDS) software update was performed in February 2022 during prior CHS warnings. Despite onset of issues under the 150,000-mile extended warranty limit per the Kia E2 Settlement, Kia denied coverage due to the minor mileage overage and directed me in a loop between Consumer Assistance and the Settlement Administrator. The defect poses a serious safety risk: potential for sudden engine seizure, stalling while driving, or engine compartment fire (as seen in related Theta II recalls and thousands of NHTSA complaints). No crash, injury, or fire occurred in my case, but the failure left the vehicle undrivable and unsafe on the road. I have service records and diagnostic reports to support this.

Our 2016 Kia Sorento had 96k miles on it, my 2.4 Liter, V4 GDI engine. I was driving it to my house on the streets, when the vehicle it completes died on me in the middle of the streets, it won't turn on, had it tow to my house. Made an appointment to take it to body shop on 2/12/2026, when it died while driving it to the auto shop, won't turn on, had it tow to auto shop. It has been burning oil for quite a while, keep putting engine oil very often. Auto shop confirmed vehicle found no codes, inspect engine oil, engine oil is very dark, manually rotated engine crankshaft, found engine seized. Vehicle has internal engine damage, possible connecting to the rods and bearings damage. Estimated repair is 9k. It is available for inspection.
