Check engine light in March of 2021. 38,800 miles. Determined to be a timing issue and parts of the engine was replaced by Bill Barth Kia in Mandan, ND. Car was picked up on 4/21/21. On 4/28/21 all warning lights came on. Car was towed back to dealership. After multiple attempts at fixes over a 4 month period of time it was finally determined a new wiring harness was needed. The new harness seemed to correct the problem and I took possession of the car on 8/20/21. It was driven around 75 miles that day to drive home. On 8/22/21 the car was driven 8 to 10 miles and then parked and turned off in my driveway at 12:35 pm. No warning lights were on at this time. At or around 1:30 pm I was notified by my neighbors that the car was on fire. My husband grabbed an extinguisher and located a 12 inch flame in the front of the car near the engine. It was quickly extinguished. …
Continues to have issues with dealership to remedy/correct recalls. Have waited for 60+ days since recall remedy was initiated in August 2024 Headlights continue to be a hazzard and due to this we had unfortunate incident of a deer running out and inability to see in the dusk of 6am due to lack of head lights. This has caused immense hardship regarding finances and maintaining a job as we are down one car and Kia has not offered and:or received all parts for any repairs of the recall. Advised if we attempted to fix one recall (power seat) then our "ticket will be closed and you will need to pay out of pocket for the headlights". However this is not consistent or within the regulations of Recalls and good faith attempts. I have already contacted an attorney to pursue legal counsel. …

While driving my suv on the highway the day I purchased it on 6/5/20 it disabled 5 times where I was only able to use brakes and pull off side of road. I was 36 weeks pregnant and had my 2 year old in the car. I didn't make it home. There was highway construction locally and no edge to pull off on if needed. We could of been seriously injured or died. It was towed to my local Kia dealer where they didn't find anything wrong with it. They replaced the battery. It seemed to be running ok then on 5/5/21 my suv disabled again only being able to use the brakes and pull over while driving it on a hilly, narrow backroad with someone driving behind me with my 10 month old in the car. Every time this has happened the suv loses all power and needs to be placed in park to be restarted. The Kia dealer has had my suv for over a week and cannot find anything wrong with it. …
OCTOBER 2024 Before the main incident Oct 2024, I started noticing slight changes in the way my KIA was operating: - Delayed response to accelerate when at a light - Tire sensors/ crash collision sensors - Lane assist pulling my off the road or into on coming traffic (random) - Intermittent Power loss while driving. - Lights not working properly. - High beams failed to operate in Sept and was told by Burlington WA KIA there was not a fix for the recall, while there for service/oil change. - Car going into parking brake when not activated. - When stopped in car is in drive, when starting to accelerate the car went in reverse causing me to hit a stump and partially tearing front bumper off. About a week after that incident I was driving home from store and car started randomly pulling car into oncoming lane. Thankfully there was not a vehicle at that time. …
Following a recent $9,000 engine replacement performed by an authorized Kia dealership, my vehicle suffered a catastrophic, simultaneous mechanical and electronic systems failure while in operation. Without warning, the vehicle triggered the Knock Sensor Detection System (KSDS) and entered "Limp Home Mode," severely restricting vehicle power. Immediately following this, the vehicle experienced a total loss of essential safety and driving controls: Steering Failure: The power steering completely locked up, creating an imminent crash hazard. Dashboard & Gauge Failure: All dashboard warning lights illuminated simultaneously, and the speedometer completely stopped functioning, leaving me unable to monitor vehicle speed. …
I have a fairly brand new 2020 Kia Telluride with only about 50,000 miles on it and one day out of no where the car won't start and now I'm getting a check ESC message. Since it's fairly new I had it jump started and the car quickly turned on and ran fine for the rest of the day. The following day the car hesitated when turning on but it started. I was driving and when I got to a light and when the light turned green and went to take off the car wouldn't go. It turned off again and would start back up. I went into the KIA forum and noticed that a lot of Kia Telluride owners are experiencing this same issue but all seem to have different resolutions from needing a new battery, or a new starter or that the IBU system is blown. …
the center infotainment screen has turned green. sometimes a hazy green, othertimes almost a solid green which affects the back up camera system when you are trying to back up and not hit anyone or anything. I have brought to the dealership and they stated the head unit is defective and needs replacement. I elevated to Kia Customer Care and they stated that because it is out of the 36,000 mile warranty they would not help. I even stated that as car is not a newer car was not asking for a brand new unit, but asked if they would at least put in a cheaper re-manufactured unit due to the safety issue and they denied that as well. I am on the kia telluride forum and multiple other people are having this issue. this is a defective part and as it is related to a safety issue needs to be replaced and covered by KIA. [redacted]
