2023 Kia Telluride engine problems

Filed Oct 26, 2026 · Electrical, Engine · OH · fire

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 actual root cause identification.

This is an update to my original the federal safety agency 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 providing this update because the frequency of occurrences is escalating — two failures in a single day — despite a repair that was physically confirmed by the dealer's own testing. This strongly suggests the actual root cause (potentially an immobilizer/smart-key system fault, IBU communication failure, or intermittent wiring/ground fault) has not been correctly identified, and the defect continues to pose an unreasonable stranding risk to occupants. I am concurrently pursuing a vehicle replacement request with Kia America under Customer Care Case #26211382.

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 when it failed to start. This is the type of defect that could strand occupants in unsafe locations or conditions (heat, cold, traffic, isolated areas) with no warning and no reliable workaround. I have video evidence of the [XXX] incident showing the vehicle's instrument cluster and infotainment fully powered with a no-crank condition, timestamped and showing the odometer reading. I am filing this complaint because the defect has now defeated a dealer-confirmed and dealer-executed repair, suggesting a root cause (such as an immobilizer/smart-key system fault, IBU communication failure, or intermittent wiring/ground fault) that has not yet been correctly identified. I am concurrently requesting a vehicle replacement from Kia America under Case #[XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On June 15, 2026, my check engine light came on. On June 17, 2026, I took it to Auto Zone, they checked the code for the check engine light, and it indicated P0016 and P0017–crankshaft issues. On June 19, 2026, while driving down the highway, my vehicle failed to accelerate. I exited the highway, and my vehicle completely decelerated and ultimately shut down. I was unable to get my engine running and had to get it towed to the dealer. It has been at the dealer for 3 weeks now. The dealer said my engine will likely need to be replaced. It is a 2023 Kia Telluride with less than 66,000 miles on it.

While driving my car randomly displays a warning that I need to shift to park or neutral immediately and turn off my engine. Sometimes my car will work afterwards, other times it will not and I’m stuck for 5-7 minutes. It happens in the middle of me driving with no warning signs. I’ve tried to ignore it and the whole car shuts off and the brakes lock up. It is very frightening. I brought it in the first time and they claimed it was my battery so they replaced it. It’s now happened 4 times and they have no idea how to fix it. My car has been at the dealership for 6 weeks now with no end in sight. They want to give me my car back but I keep pushing back. They were able to duplicate the issue one time but no error codes came up. It happened to the technician at a stop light so they’re claiming it’s probably only when stopped. Which is not true, so they don’t see the safety concern!!! I’m 8 months pregnant and do not feel safe driving a car that shuts off in the middle of me driving! I have also opened up a case with corporate. I have seen Reddit threads and so many complaints regarding this issue. Specifically on 2025 tellurides, although mine is 2023. I want out of this car because I genuinely fear for mine and my families safety in this car. I can’t believe this isn’t a bigger issue!!!!

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. The dealer was unable to replicate the condition during the service visit and did not perform a repair. The defect is intermittent in nature, which makes dealer replication difficult, but video documentation of the fan running with the vehicle off and unattended exists for multiple incidents. The vehicle has not been inspected by police or insurance representatives. No warning lamps illuminate during or prior to the event. The fan simply activates after shutoff with no prior symptoms.

Multiple times over the course of six months the vehicle would turn itself and all electric components off while being driven, with no warning. The car would then refuse to restart.

Engine shuts off without warning while driving. First reported to the dealer on XXX (approximately 12,000 miles) and has continued for 2.5+ years despite repeated repair attempts. Shutoffs typically occur at low speed while decelerating, such as turning into neighborhoods or approaching stops, but have also occurred while coasting at 33 mph on a busy road with cruise control active (August 8, 2025). Frequency has varied from roughly every 1,000 miles to severe clusters: three shutoffs within one hour on [XXX] and again on [XXX], and five in a single day in mid-August 2025. The dealer reproduced the failure with diagnostic equipment connected in August 2024. Most recent events: XXX;XXX (quit while coasting at 20 mph on a busy four-lane road with cruise control engaged);XXX (quit while slowing to turn onto a neighborhood street, 87 degrees F, A/C on high). The vehicle usually restarts immediately, but on [XXX] it would not restart for 5-7 minutes. After restart, cruise control retains its previous set speed, indicating an incomplete power cycle. The dealer (Kia Store East, [XXX]) has attempted repairs since September 2023 under Kia case #XXX, including crank position sensor replacement, MAP sensor replacement (June 2025), and a four-wheel-drive coupler replacement plus software update (October 2025); shutoffs continued after every repair. Historical fault codes include P0068 and B1763. Events have occurred in traffic and at intersections with several near-misses, including one that nearly caused a collision in an intersection on XXX. This is a family vehicle regularly carrying children. Repair orders are available upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
