Recall states to not drive vehicle due to HECU which can result in an engine compartment fire. I have contacted 3 dealerships and corporate. There are 15,000 dealerships/service centers that have technology/technical issues. I have spent 3 days, and 12 hours trying to get assistance. I'm being told corporate is not providing any additional support or payment to individually owned dealerships. Expecting them to cover additional expenses. I am disabled and need to go to treatments/procedures multiple times a week. They are backed up 1-2 months for an appointment. Consumers are to pay everything up front and then 90 days later request a reimbursement. They will not provide or pay for a rental or loaner car until the car is being serviced. Therefore they are leaving me with no vehicle for up to 2 months as their letter clearly states that the vehicle is not to be driven and is unsafe. I should not be inconvenienced because Kia made a mistake and is now having to perform a recall, 15,000 stores are not able to perform because of technical issues, they are so far behind in their service appointments which should not have any effect on me and I should not be responsible to pay for any of this and they should absolutely provide me with the vehicle and not leave me with no transportation for 2+months. I am unable to get to my appts. for treatments, my daughter cannot Drive to work. And they have absolutely no solution for me and telling me that there is nothing that can be done other than me paying $45/day out of pocket. they Stated that I personally would be charged to do a full diagnostic test to confirm that there are no safety issues, however corporate stated that it was required in order to get my car back. This has been an absolute nightmare, I am also wanting to know if ada would get involved in something like this as they are not making any type of reasonable accommodation for me. There has to be a law preventing this that they are required to provide a vehicle unt

Defect discovered by KIA September 2023 Affected owners not notified until November 2023 As of March 1, 2024, no updates. After six months, if no "fuse" is available, entire HECU should be replaced. Vehicle's exterior has significantly deteriorated since being required to park outside. Additionally, seriousness of fire hazard restricts use of car.

There's something going on at the Kia dealership in Wake Forest (Westgate). Per the current recall notice, the lights came on that were highlighted in the notice ( -??MIL-??, ABS warning light) so I had my car towed into the dealership. They claimed my car had a bad battery and the problems were not due to the recall situation. I took my car out of there and straight to auto zone, about 200 feet from the dealership. My battery tested fine. Not only this, the lights (check engine, and others) were no longer illuminated and the radio was mysteriously working again. I'm not sure what they did to my car, but they charged me over $200 for a diagnosis. Not only this, they cited several other issues with the vehicle that I nor my master mechanic were aware of. They had my car for several days without so much as a phone call. In addition, while I was waiting for the keys to my car (which took 15 minutes to obtain), I overheard the other gentleman inform a kia owner via phone that her car was not covered under the warranty because she had over 150K miles on the car. I'm so disgusted. This is what happens every time we have to take a car into a dealership. They're full of baloney.

It appears I have a defective oil pump in the car which I think is what caused the engine to go bad to begin with. I am requesting that KIA of Denham Springs be authorized by the main office of KIA to install a new oil pump in my car after the new motor is installed, otherwise the new motor will probably go bad and will result in Kia having to install another motor for the car. I hope you can step in and assist me in getting a new oil pump installed as this would be a safety issue of the car breaking down on the road and could result in myself or other passengers possibly stranded on the highway. A engine compartment fire could happen if the engine gets too hot due to the deflective oil pump no keeping all engine parts oiled properly by the defective Oil Pump. I am requesting that the National Highway Traffic Safety Administration's office look into this matter. Thanks for your assistance Tommie McMorris 985-969-8995 email: tommieap@charter.net

After driving the car over 15 miles, the Check Brake Light comes on, activating my emergency brake, slowing the car down and preventing me to accelerate. This happens on the freeway, where traffic is fast and my decelerating car puts me and those around me at risk of collision. Once it occurs the first time, it happens again a few minutes later. I have to frequently veer off the side of the freeway, turn off the car, and then turn it on again for the Check brake light to go away and for me to travel once more. This has been a problem for a couple of years with me trying to get the issue repaired, and documented in my visits. Kia and other service operatives have repeatedly not been able to replicate the error in their care, however they never drive it long enough for it to occur. I-??ve spent a lot of money now trying to fix this problem and have videos and photos of it occurring. The last time it was inspected they only drove it 6 miles and said there were a lot of little codes going off but weren-??t again able to replicate the problem I had been describing. It first appeared 2 years ago and I can feel it start to come on when I-??m not able to accelerate my car any further like there is an added resistance. This then amounts to the check brakes display to appear with the emergency brake icon always accompanying it. It makes a scraping, gargled sounds and slows down the car. Overall it has affected the overall drive of the car and braking system as it is growing harder to stop the car when driving. The brakes have been repeatedly checked as well as the fluid and it-??s normal, so it should be braking normally. This car has had other issues in the past that have been fixed but this has continued and has been a growing issue that is not being resolved. I-??ve googled this issue with others expressing the same issue without ANY viable solution from Kia so I know I-??m not alone in this. It-??s not safe to drive. Also I tried uploading the videos but it only allowed the pictures.

I was driving out of town and when I went to accelerate and the engine had seized, the brakes had locked up and I lost power steering which almost resulted in an accident. On the dash was showing the engine, oil, and esc light, which were not on the dash before and there was nothing wrong or weird going on with the car prior to the first incident to even indicate that something was wrong. Had to get the car towed home then realized there had been a recall on the engine. Contacted the kia manufacturer and they had towed it to a kia dealership where they replaced the engine. Waited 2 Months to get my car back, the dealership let me leave with the ABS and Eps light on the dash, and couldn't give me a reason why the lights were still on. I had it for 3 days, it drove okay and now it no longer drives nor does it start. I was stranded because the car wouldnt start again giving the same issues as before the recall repair was done, with only accessories turning on. On the dash it only shows Engine, Oil, Eps and battery light. Found the Serpentine belt already coming apart and misplaced, found strips of the belt laying in the bottom of the hood. Also had found out the entire engine block ROCKS BACK AND FORTH while car is in motion. If I had driven the car any longer the belt would have completely snapped and would most likely result in an injury or worse. With the Engine movement that is also going to cause other damages to the car and more safety hazards. I have not even known about the engine recall on this car until after everything happened and when the car was purchased no one had notified me in anyway about the recall. Now they refuse to cover towing costs back to the dealership because the "5 year warranty had expired" When this in no way is my fault. Second incident was Oct. 17th 2022.

Safety: It appears the vehicle in question has had Engine, Electrical, and Driveability issues within less than 8,000 miles of it being on the road the First record of this vehicle show's one owner, purchased not from a Kia Dealership but a third party. The Carfax history showed there has been a driveability issue an ECM Module has been replaced twice" less than 30,000 miles" It's Believed that the warranty or millage has been used as a reason to deny repair and or Because as the Recall on the engine states it is undetermined as to what is causing a malfunction but it has or will result in fire. This becomes a liability for those who offer works on the vehicle. Something within the vehicle is without warning causing the vehicle to randomly fail while descending from 65-85 miles an hour. There are also sudden jerks that randomly accrue. rendering the car hard to maintain direction. Imagin a first-time driver attempting to handle this on a busy Highway in Texas - The day we acquired the car we took it to KIA to do a full inspection - oil change, etc- The report given was that there are no problems identified but a computer module may need to be changed. We also asked that they give us an appraisal it was at that point they said that the car had a salvage title. Which the seller who sold it us ARELLANO AUTO SALES sail the title was clean. Last year a recall on the engine was issued. the insurance company determined the vehicle a total loss since how the car was branded a lost because it appears Kia refused to Fix the car, While everyone else says they can't recreate the issue for fear of liability. So here are with a car that has an undetermined engine issue that causes other electronics to malfunction. The vehicle has been seen at KIA dealerships according to the carfax. It's been seen. By two other service facilities and all have come up with something that may needed to be service while nothing has fixed the car

My car loses power when I use the horn. It happens while parked with the engine on and in traffic. Initially, I thought it was faulty electrical problem because there were 3 active recalls needing to be fixed. I recently took my vehicle to a certified Kia service center to get the recalls taken care of and additonally, had the A/C compressor, struts, and a belt replaced. I also described the issue of engine power loss when I use the horn with service tech and attempted to demonstrate. However, my car didn't duplicate the issue. I'm not sure if the techs tested it thoroughly during the days it was being serviced. The final detailed bill states that the car wouldn't duplicate the issue. I'm currently satisfied with the fixed recalls, A/C, belt, and other minor repairs. I'm highly concerned and frustrated that I'm still experiencing engine, acceleration, RPM, and A/C failure whenever I need to use my horn. A couple of days ago while in traffic, I had to blow the horn because a distracted driver nearly side swiped me. As a result, my car loss power. I couldn't accelerate and the transmission wouldn't shift. I ended up doing around 30mph until I made it to a safe destination. I called for help, but after I turned the car off and back on, it was as if it never happened. I'm furious about it because the distracted driver proceeded to tailgate and intimidate me out of anger. Lastly, it was not professional or caring to be laughed at when I voiced this problem at the service center. I need help and answers before something more terrible happens. The number of engine and electrical complaints are startling. I'm hoping that my issue will be taken seriously and looked into. I'm not comfortable driving my car.
