“Vehicle: 2015 Kia Cadenza Issue: Open HECU Safety Recall — Fire Risk I am the owner of a 2015 Kia Cadenza with an open HECU recall related to a known fire risk. I have been experiencing a burning smell inside the cabin of the vehicle, consistent with the recall defect. Upon contacting Kia Consumer Assistance, I was advised not to drive the vehicle due to the fire risk and to have it towed to a dealer. However, after calling multiple Kia dealers in the Pittsburgh, PA area, the earliest available appointment is over one week away. Kia Consumer Assistance called dealers on my behalf and was unable to secure an earlier appointment. They said they could "Look into a potential reimbursement of $55/day for a rental vehicle." but could not confirm a loaner. I am concerned that Kia is not treating this recall with the urgency a fire risk warrants. I WAS NOT PROACTIVELY CONTACTED ABOUT THIS RECALL DESPITE MY VIN BEING AFFECTED. I am now without transportation, my vehicle cannot be safely driven or stored in an enclosed space, and I am waiting over a week for a repair on a vehicle that could combust. I am requesting NHTSA review whether Kia is adequately addressing this…”

Engine

13 reports
“Engine seized. 3.3L Lambda II GDI. This is the 2nd Hyundai/KIA product that the engine has seized on me. Both with bearing failure. Neither on the list of recalled engines. You need to do a more thorough investigation into Hyundai/KIAs engines. The brands share the same power trains across the entire line up for a number of years. This class of engines has been produced for YEARS along with the Theta class of engines that you already forced Hyundai/KIA to recall. This seizure has cost me THOUSANDS and additional THOUSANDS that I am unable to pay. I was forced to do a voluntary surrender of the vehicle due to this repairs! BEFORE completing the suggested maintenance totaling over 5 thousand dollars the service tech should have warned me that the engine wasn't going to last much longer instead of telling me that the repairs were necessary and could be dangerous. The dealer and this company took advantage of me and who knows how many others! NHTSA needs to do something about Hyundai/KIA!”

Visibility

5 reports1 related recall
“While driving on the freeway my rearview mirror suddenly came down causing a Crack across the windshield. "Recall on windshield"So I looked up recalls seen there is one for a loosening windshield. I took it to the dealership he said that couldn't happen and there is no way he can take windshield off to find out due to it being cracked. It's obviously the reason why. I can feel cold air when driving on freeway driverside top of windshield now that it's cold out. I was sent on my way. [XXX]”

Exterior lighting

“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!”

Steering

“The same engine in these 2015 - 2016 Kia Cadenzas is the same engine present in the Kia Sorentos which have been being investigated for early failure, My kia cadenza stalled at 63 miles per hour on route 73 in new jersey and ever since I've been terrified of it, the dealer (Burlington Kia of South Jersey) told me this is common, and they have stingers and most cars with this same 3.3 engine in for the same failure and it just boggles my mind, I was driving and stalled at 68 while cars are flying by me all because of a known failure? Something that is common and known? I looked up what my diagnosis of my engine was when it was towed into the dealer and my searches lit up with the same problems and the same story from others, I'm just more concerned on how this isn't a recall, if it's known the vehicle can smoke overheat and stall while moving why not warn anyone? If I would of known this I could of done something rather then be put in a situation where I bought a $11,000 car with no warranty as it had only 85k miles, and it blows up in less then a year due to something that is known. The only reason I came to find out about how common this is, is because my…”
