“Backed into a parking spot and engaged the epb. I heard the usual motor sound except it kept sounding for about 30 seconds. I disengaged the epb and put the car in drive to pull forward and the auto hold and electrical power brake (epb) got stuck and would not released although it was not showing on the dash as active and then, I tried to go forward and the auto hold and epb lights came on and were amber. I turned the car off waited a few minutes hoping for a reset and turn the car on and the auto hold and epb were no longer displayed. I again put it in drive and the break was still stuck. …”

“The smart key for this vehicle is a new design, released for the 2013 kdm Kia k7, and has a release button where the plastic key/remote part may be removed to expose a metal center-cut key that can be used on the driver's door, trunk, or glove compartment. The release will detach the key well before the button is flush with the plastic body, allowing many different normal motions to release the key. On many occasions, just regular movement has released the key and it has fallen off in my pocket. …”

“2014 Kia Cadenza Continuous knocking and rattling sound since car purchase and now engine started smoking and from what mechanic states, the engine is now blown after just paying off vehicle. There was a Class Act settlement in other Kia models but not for the Cadenza. After researching & finding out this make of car has numerous engine issues, I contacted the Settlement Dept but was told my model car was not included. …”

“KIa informs me that my Hydralic Electronic Control Unit may short circuit and cause an engine fire. Don't park close to anything. WHEN THE REMEDY PART IS AVAILABLE, KIA DEALERS WILL REPLACE THE HECU FUSE. If it's just a fuse, why have I had to park my car outside at risk of winter weather, vandalism, and theft, for the past month and a half? I hesitate to operate a vehicle which may blow up. I therefore do not have use of my car. And KIA is taking ENTIRELY TOO LONG to fix this recall. …”

NHTSA complaint #11563200, filed 2024-01

“I received an Interim Notice of Safety Recall Number 23V652 dated November 14, 2023 from KIA regarding the HECU unit having a possibility of an electrical short circuit which could cause a fire. The recall notice recommends parking outside. It is now entering April of 2024. I sent a letter to NHTSA dated February 9, 2024 complaining of the extended time for KIA to provide the parts necessary to service the recall. Now the time involved is becoming egregious. NHTSA should be demanding KIA to service the recall in the interest of public safety. I request NHTSA do so.”
