KIA Complaints

My entire Dash went Black. I could not see speed, gas level, milage. This is an extreme Hazard! I brought the car into "Crown KIA" in Clearwater to run a Diagnostic Check for 0.5 hour at $150 and they could not find the problem. I had no money to pay for additional time! I did research on this and found that this is a common problem with KIA's no matter what year!! Just because my particular VIN # is not on the recall should not absolve KIA from their duty to provide a safe reliable car!

Dashboard / cluster screen went completely black on two separate occasions while driving.

When the temperature is around zero my dashboard will not come on. I have been to the dealership 5 times for this issue. It takes me an hour to get to the dealership and by the time I get there it comes on. Dealership (Ken Ganley) states they can’t find the problem if it’s on. This is total bullshit, they know they have an issue and can fix it. Bought the car brand new. I believe it’s a safety hazard when I have no speedometer, gas guage or indicator lights. This has been going on since I purchased the vehicle in July 2024.

The engine is a problem and all I’m ever told us “ this vehicle is know to have engine problems. This is dangerous to have in the road. Kia is aware of this. Why sale the vehicle knowing this and not disclosing this info to the consumer upon purchase. There is no truth in lending. It’s plain sight robbery. What if I’m far from home and stranded because vehicle set fire or broke down in hazardous condition weather. I constantly needing oil changes because of this engine. The dealership is aware. They tell me to trade it in or get rid of it because it’s going to go for a fact. I’ve never missed oil changes. I put oil every time the oil indicator light comes on. Now for the 3rd time the check engine light is on. 2 times for misfire code. The vehicle engine holds sludge no matter how much you get oil changes. The mechanic told me this year make and model is known for this very fact. I want my money back. Kelly blue book don’t give enough. I was scammed into this car but I managed to pay it off. A car the sales person scammed me and wouldn’t take the vehicle back. I complained to the general manager. They always act like he wasn’t available. They kept claiming new ones started. After almost a year of those games I had to move and the case never got solved. But even when I complained their maintenance person stole my rims. They told me prove it. Just all bad experience. I just want my money. Even if they gave me another engine. It’s still going to be the same problem. A bad engine. 2016 Kia optima’s should not have been continuously sold with them knowing it has bad engines. Even the headlights don’t work. Very dim. Car smells like burning fumes when driving. Please please help. This isn’t fair lending practice. People trust them and they are dishonest sellers.

Infotainment screen is blank most of the time. Backup camera works intermittently. Dealer confirmed head unit failure and stated software updates cannot be performed. Quoted approximately $7,500 for full replacement. Issue has been occurring for over two years, beginning while vehicle was still relatively new. Creates unsafe reversing conditions due to unreliable federally required backup camera display. Dealer classified as infotainment module failure. No recall issued despite widespread owner reports of similar failures.

About 10 miles from home a warning saying to check the electrical system came on the dash and the car would not go faster than about 25 miles per hour. We had to limp back home, turning the car off every few miles as it would start aggressively beeping to turn off the car. After getting it towed to the dealership, it took them several weeks to determine it was the ICCU and fuse, and I did not take possession of my car back for nearly 8 weeks. While this was under warranty, I am still currently waiting for reimbursement on the tow to the dealer and the rental I had to get for 3 days before the dealer could get me a loaner.

My 2016 Kia Optima experienced a sudden catastrophic engine failure in July 2025. The failure is consistent with widely reported Theta II engine rod bearing defects that cause engine seizure and stalling. The vehicle did not receive the Knock Sensor Detection System (KSDS) update prior to my ownership, and I was never notified of this critical safety-related update. The engine failure occurred without warning and could have resulted in loss of power while driving, creating a serious safety risk. This vehicle model year has a documented history of engine defects and class action settlements related to premature engine failure. I believe this represents an ongoing safety defect. I am requesting that NHTSA review this failure as part of its investigation into Kia Optima engine defects.

My vehicle is included in NHTSA Recall 25V099 / Kia SC336 for defective piston oil rings. The vehicle has experienced stalling, loss of power, knocking noises, and oil consumption. The engine behavior is unsafe and consistent with recall-related engine damage. Kia closed my case based on a dealer’s subjective noise judgment, but no mechanical engine testing (oil consumption, compression, or cylinder inspection) was performed. The recall remains incomplete and the vehicle continues to present a stalling and fire risk.

Immediately after delivery, the instrument/infotainment display malfunctioned, froze, and became unresponsive. Apple CarPlay failed, and phone calls distorted or dropped. After reporting the issue, I discovered that this VIN is subject to Safety Recall SC359B, with a recall date of December 17, 2025, and a status of RECALL INCOMPLETE / NO REMEDY AVAILABLE. This recall existed prior to the sale. The recall is confirmed by the Kia owner app, Kia/NHTSA VIN lookup, and the dealer’s internal campaign report. Despite this, the dealer stated in writing that there were “no open recalls” and refused to unwind the sale, mischaracterizing the defect as an “audio panel” issue. I am submitting this to document a retail delivery of a new motor vehicle under an open, VIN-specific safety recall with no available remedy, which constitutes a violation of federal motor vehicle safety law (49 U.S.C. §§ 30112 and 30120). I request review by the Office of Defects Investigation and Recall Management Division.

Vehicle developed a cylinder 3 misfire that progressed to engine failure. The engine began running rough and lost power during normal operation. Dealer diagnosed internal engine damage and advised that a complete engine replacement is required. Prior to failure, the vehicle experienced significant oil loss, with oil leaking and rapidly depleting despite proper maintenance. Oil levels dropped abnormally between services. No adequate warning was provided before the engine condition worsened. Failure resulted in loss of engine performance and required towing. Vehicle was properly maintained. Repair cost exceeds reasonable expectations for vehicle age and mileage. Dealer advised that required engine parts are on backorder, leaving the vehicle inoperable for an extended period.
