2023 Kia Telluride electrical system problems

“There was a low-speed collision with a deer (approximately 10-15 mph). The vehicle continued to run fine after the collision and we were able to drive it home. After the next start, the engine was shaking all over and started smoking from behind the engine. The battery was disconnected but it continued to smoke. After further inspection, we were able to find a fire and extinguished it using a fire extinguisher. We had issues with this car prior to the collision where the engine would misfire after the car would get wet, but would only produce temporary codes. This was checked out by the dealer and we were told there's nothing that they can do. A few weeks prior to the collision it happened again and the check engine light went to a confirmed/permanent code and it was related to cylinder misfires. If we would not have had a fire extinguisher or had been able to roll it away from the house, the occupants, vehicle, and house would have been in danger of the fire. The source of the ignition has been confirmed to be the ignition coils, but the root cause of this has not been determined and it has just been assumed that it is related to the collision, without an…”

“The vehicle electrical system could be a fire hazard since the vehicle electrical system is incurring parasitic draw down of the battery. Believe there is a class action lawsuit filed relating to the problem. It is well known issue wit KIA Corp while the dealerships play dumb. Thank you.”

“This is an update to my original NHTSA complaint (ID 11755209) regarding an intermittent no-start/no-crank defect on my 2023 Kia Telluride (VIN [XXX]). Since my original filing, the identical defect has recurred twice more, on XXX — once at approximately 1:01–1:30 PM EST and again at approximately 5:03–5:17 PM EST, the same day. In both incidents, the dashboard and infotainment system powered up normally, but the vehicle would not crank, consistent with all prior occurrences dating back to XXX. This brings the total documented occurrences to six between XXX and August 8, 2026, including two in a single day. In both August 8 incidents, my wife was stranded and had to be picked up because the vehicle would not start. This follows a dealer-confirmed and dealer-executed starter replacement (Kia of Cleveland, RO dated XXX, part #36100-3L160) that was performed after the dealer duplicated the fault on the vehicle and on a bench test — and a 4th recurrence on XXX, just 10 days after that repair. I have video evidence of all four August incidents (XXX, and the two on XXX showing the instrument cluster and infotainment fully powered with a no-crank condition. I am…”

“My 2023 Kia Telluride (VIN [XXX]) has an intermittent no-start/no-crank defect that has occurred on four separate occasions between [XXX] and [XXX] (mileage range 49,850–51,180). In each occurrence, the dashboard and infotainment system power on normally, but the engine will not crank when the start button is pressed, with both key fobs. The fault clears itself with no consistent trigger, making it undetectable by standard diagnostic scans after the fact. The vehicle was taken to Kia of Cleveland (2492 South Lee Highway, Cleveland, TN 37311) three times. On the first two visits (6/18/26 and 7/1/26) the dealer could not duplicate the fault and returned the vehicle unrepaired. On the third visit (7/17/26–7/27/26), the dealer successfully duplicated the no-start condition both on the vehicle and on a bench test after removing the starter, and replaced the starter under warranty (part #36100-3L160). Despite this confirmed and completed repair, the identical no-start condition recurred on [XXX], only 10 days and approximately 250 miles later. This is a safety issue: on [XXX], my wife was attempting to leave for work with our twin 5-year-old daughters in the vehicle…”

“Driver Assistance Warning (DAW) warning bells and dash sign "Driver Needs a Break" with Coffee Pot showing goes off constantly. Even with safest driving possible, on purpose safest driving, the warning and sounds goes off every few miles and few minutes. KIA dealer has kept car for 2 weeks and say they can not duplicate and I drive it (Perfectly) and it goes off. this is a 2023 Kia telluride , previous year models and later models you could turn off or turn down sensitivity of this warning. KIA eliminated the owner the opportunity to disable or turn down this warning. It is a safety hazard because it is always going off, causing the driver to take his attention from the road to the dash every few minutes with the bells and coffee pot Take A Break Warning . KIA will not do anything about it.”

“The engine cooling fan activates at high speed and runs continuously for an extended period — in one instance, overnight — after the vehicle has been turned off, locked, and left unattended. This has occurred on multiple occasions. No warning lamps or messages appear before or during the event. The vehicle gives no indication anything is wrong; the fan simply runs at full speed on its own, without the ignition on, for hours at a time. The component involved is the engine cooling fan and/or its control module. Based on owner community research, the likely cause is a faulty signal being sent to the Engine Control Module, which triggers the fan to run even when the vehicle is not overheating and is fully shut off. The component is available for inspection. Safety risk: The vehicle is parked in an attached garage. An electrical component running uncontrolled and unattended for hours inside an enclosed structure attached to a residence poses a credible fire hazard. A bedroom is located directly above the garage. This is not an inconvenience — it is a fire risk to occupants of the home. The problem has been reported to an authorized Kia dealer on multiple occasions.…”
