KIA Complaints

My wife was pulling in spot and car took off at high rate of speed and hit parking pole . Kia corporate after 2 months tells me nothing wrong with vehicle . i found on kia of Manahawkin they have a page on this issue forced acceleration and cause so how they can tell me no it doesn't happen also goggle searches show this a reported issue , and recently friend of my women in Florida her car did the same thing .

The vehicle began making a clicking/popping sound when turning the steering wheel left or right, especially at lower speeds and while turning into parking spaces or driveways. The exact component causing the issue has not yet been fully identified, but it may involve the steering or suspension system (such as the CV axle, tie rods, or steering components). The vehicle is available for inspection upon request. The problem puts my safety and the safety of others at risk because the clicking noise may indicate a failing steering or suspension component, which could potentially affect steering control or vehicle handling while driving. The problem has not yet been officially confirmed by a dealer/manufacturer, but the issue is consistently reproducible whenever the steering wheel is turned left or right. The vehicle/component has not yet been inspected by the manufacturer, police, or insurance representatives. There were no warning lights or dashboard messages prior to the issue. The clicking noise first appeared while turning the steering wheel during normal driving and has continued since then.

The vehicle experiences major engine performance issues following a replacement engine installation (approximately 8,000 miles on the new engine). Additionally, the catalytic converter is malfunctioning, the steering exhibits significant pulsation during braking, and the suspension system is malfunctioning. These combined defects create an unsafe driving condition and pose a serious risk to the driver, passengers, and other motorists.

I bought this car in August 2025 and I have already gotten three cracks in the windshield. This seems very off compared to all the other cars I’ve owned, which most have had none or maybe one small crack from debris off the road. This could cause a problem cracking so easily that I’m afraid if it hits just right, I won’t be able to see at all while driving. It is available upon request. I have not taken it to the dealership to be “reproduced” no warning signs or signals in the car

The contact owns a 2021 Kia K5. The contact stated while driving at an undisclosed speed, the vehicle shuddered. The check engine warning light was intermittently illuminated. The failure occurred on several different occasions. The vehicle was taken back to the residence. The vehicle was taken to a dealer to get a diagnosis however, the failure cause was unidentifiable. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 86,000.

The dealer stated my engine repair is not covered under the recall/warranty because an ECU software update was not performed. I was quoted $8500 for engine replacement (Long block). I have owned this vehicle for 2 months, going on 3. I am requesting a review of whether this vehicle qualifies for any engine recall or safety-related warranty coverage, as the explanation provided by the dealership appears inconsistent.

The headlights and dashboard lose power intermittently while driving at highway speeds, specifically triggered by using the turn signal. This is ongoing since January when I started having to take it for a recalls.More things kept happening. I kept having to have more repairs. Every time I went, I told them about this and it just keeps going on. Today I took a huge list of things they should check to see why it’s doing this. This is the following list that I gave them -2017 Kia Forte - Service Request: •Issue: Headlights/dash icons flicker specifically when using turn signals. •Issue: Average MPG keeps resetting (Computer Brownout). •Mandatory Checks: 1Multi-Function Switch (internal short). 2Manual Voltage Drop Test on the G01 Ground Point. 3Alternator Ripple Test (check for "dirty" power). Last night on my way home from my daughter’s house which is a 50 minute drive, it was in the dark pouring rain and no longer than I had got started going home, I used the turn signal and my lights flickered a little which that’s what they’ve done before. Then the icon inside the car for headlights flashed on and off, lights inside got very dim and then my headlights got so dim that I had to follow other cars that had LED headlights down an interstate at 65 mph or less safely just to get to my exit to get home for over 45 minutes. I have mentioned this to them repeatedly, but I gave this list to them this morning. I called a little bit ago just to check on things and I was told “well we’ve been driving it for over an hour and we can’t seem to get it to act up”. I said are you not going to do the things that I stated and actually physically touch and look and not just sticking it on a computer. He rudely asked- what are you talking about? It’s all computer. That’s what we do.I’ve had to deal with this since pretty much the middle of January 2026. We are now here at May 7 and it got at its worst last night and horrified me and my safety.When I have car will upload docs

Out of town July 12th 2025 my 2020 Kia Optima engine started having problems. I tried to get to my hotel but it was obvious I was not going to make it. I pulled into the nearest station and was told my car had no oil. There were no signs of leaking oil and no warning lights so they changed my oil and I was able to made it home. Shortly after I broke down again at night and pulled into a parking lot again no warning and no oil. I had to call someone to get oil and from that point on I had to put oil in my cart every other day with no signs of a leaks and no warning lights. It has become to dangerous to drive and the engine has now failed and knocking and shaking has caused me to park my car and not drive it. I am deeply concerned about the risk of catastrophic engine failure and the potential for fire, which has been documented in similar cases. Despite having the Knock Sensor Detection System installed, my vehicle continues to exhibit these dangerous symptoms. I sought assistance from Landers Crain dealership and KIA; however, they declined to properly evaluate or service my vehicle along with KIA declining according to the KIA Regional Manager. This lack of support has left me with an unsafe, undrivable car and no clear path toward resolution. The Center for Auto Safety Key Affected Vehicles (2.4L GDI) Kia Optima 2011–2018 (some 2019) exact same engine in 2020 Optima Kia Sorento 2012–2019 Kia Sportage 2011–2018 (some 2019) Details of the Recall and Settlement The Problem Manufacturing debris and tight tolerances can cause connecting rod bearings to fail, causing knocking, seizure, and potential engine fires. The Fix Dealers will update the software with a Knock Sensor Detection System (KSDS) to detect rod bearing issues before failure. My Optima has the KSDS installed but failed. Warranty Extension As part of a class action settlement, Kia extended the warranty on these engines to 15 years or 150,000 miles, provided the KSDS update is installed.

My safety is put at risk. My car has stalled two different times on the highway. I was able to get it off the road after restarting the vehicle and coasting out. The engine was worked out by Kia of Mission Viejo. They stated it was not due to Rod bearing, although I was told on a separate occasion that there was metal in my oil in the same scenario then when they submitted the video to Kia, they said they only saw the burnt valve my check engine light has went on a total of three times I’ve had the same exact work done three additional times as well as the knock sensor having to be replaced because it went off and burned out due to what happened on the highway. My car is part of the theta engine issue with Kia

The contact owns a 2016 Kia Soul. The contact stated that an abnormal, knocking sound would emit upon depression of the accelerator pedal as a check engine light appeared on the instrument panel. The vehicle was initially taken to an independent mechanic where the diagnosed the vehicle with a defective rod knock sensor; he was then advised to no longer operate the vehicle. The vehicle was later towed to a dealer where they discovered that engine rod#4 had become defective which led to engine failure. Upon investigation, the contact discovered NHTSA Campaign Number: 19V120000 (Engine, Engine and Engine Cooling) which he linked to his failure. The manufacturer was then notified of the failure and the contact was informed that the vehicle was already serviced for the recall prior to him owning the vehicle. The vehicle was not repaired and remained in his possession. The failure mileage was approximately 90,000.
