At or around 66k miles my vehicle stalled then shut off in traffic. No warning or signals. My vehicle went into limp mode. KSDS Knock sensor campaign installed prior. Oil had been consuming at a abnormal rate causing me to do oil changes more frequently and in between changes adding oil. Towed it to dealership because I was told as long as I had the KSDS update and maintenance records of which I did myself because it became expensive and records show on Carfax. After dealer mechanic looked at vehicle said I needed a new engine and Kia Corporate denied my claim claiming it was neglect which is absolutely untrue! They didn't even accept my records although on Carfax. With only 66k miles and being denied my vehicle sits worthless because Kia won't honor its warranty or recall. I even purchased gap insurance originally totally lost of money. I'm afraid my vehicle will catch on fire as it's been sitting for several months in my driveway.

after completing a routine oil change earlier in the day, the engine seized and the car had to be towed. When contacting Kia I was told their was a recall and if the knock sensor wasn't installed we are responsible. I communicated that we were unaware of a recall and were never notified of one as we are the 2nd owners of the vehicle. I later received in the mail a re-issue of what they claim to have sent out originally and was instructed to take the car to the nearest Kia dealer where they have since denied the repairs.

On December 14 2022 I had my oil changed at a service center. On December 14 2022 later in the day after the oil change service had been completed my vehicle vehicle began to sputter then stalled while driving down the road almost creating an accident. There were no warning lamps messages or other symptoms prior to stalling on the road. As the vehicle began sputtering and stalling the warning lamps then became illuminated. I coasted my vehicle to safety and parked it. I scheduled the first available appointment with a Kia dealership and had it towed in. They did an inspection completed a recall and said I needed a whole new engine and only the short block was covered. I have service records for regular maintenance. I have contact the dealership and manufacturer with a response that the engine replacement is not currently covered at this time. I believe that if the vehicle was at a higher speed or more traffic was present that the engine failure could have caused serious injury or fatalities. My vehicle is available for inspection if requested. My vehicle is still located at the Kia dealership. I currently do not have an invoice or paper receipt from them. I do have an email from the dealership stating a new engine cost before taxes. I am unable to upload the file on this page for some reason. I can make it available if needed.

Anti Theft Security system is non-existent. There is a current known issue on the internet on the ease of theft of any Kia or Hyundai to certain years of manufacture. I am currently a single disabled person that could be a victim of vehicle theft because of a lack of this security software that Kia did not include on my 2015 vehicle. This Kia/Hyundai known issue could potentially leave anyone stranded in a dangerous situation. All other prior and current vehicles are equipped with the security software. Currently Kia & Hyundai has provided Lock bars for certain police departments to hand out, however.. not in my area. I am receiving warning letters from my Insurance company and have heard of some totally dropping coverages on all vehicles manufactured without the security software. This is a very dangerous situation and I believe that ALL VEHICLES AFFECTED SHOULD BE ISSUED AN IMMEDIATE RECALL AND SOFTWARE UPDATE PROVIDED BY THE MANUFACTURERS AT NO COST TO CURRENT OWNERS OF THESE DEFECTIVE VEHICLES. A proposed class action lawsuit was started in September 2022. In the meantime.. what happens to innocent people who go to a grocery store or doctors office only to find that their car had been stolen while they were inside" Or what happens when they can no longer receive insurance coverage because of the ease of this known lack of security originally promised from the manufacturer" These particular Kia/Hyundai's are missing a "key" anti-theft device..their keys lack computer chips for theft "immobilizer" systems that other car manufacturers have as a standard theft deterrant during those same years of manufacture & currently have on all new vehicles. A MANDATORY RECALL FOR REPAIR SHOULD BE ISSUED IMMEDIATELY BEFORE ALL INSURANCE COMPANIES REFUSE TO INSURE THESE VEHICLES! Anti-Theft technology was included on the sticker price but not installed! I am afraid to go to the grocery store!!

While driving the vehicle on Tuesday 1/17/23 giving it gas, the engine stopped running. I was going about 45 mph when the engine stopped, multiple lights on the dash turned on including the engine light, oil light, and battery light. I had to coast the car to the side of a 3 lane road. I turned off the car, waited a few moments and tried to turn the car on. The lights went on but the engine did not start. I had the car towed to an auto shop who then advised I should have it taken to a Kia dealer as there is a recall on the vehicle. The dealer has had the car for a week and has only said that the engine is seized and that they can not provide more information without me paying to have the engine taken apart.
