Kia Telluride adaptive cruise problems

Filed Nov 2, 2026 · Acceleration, Electrical · NJ

On XXX, at 48,787 miles, the digital instrument cluster on my 2024 Kia Telluride EX – X line failed completely upon startup. The speedometer, tachometer, fuel, gauge, transmission, gear, position, indicators, turn signal indicators, and all warning lights became in operative. Simultaneously, the blind spot warning indicators in both exterior mirrors, cruise control, and audible parking – distant warning stopped functioning. The exterior lights, turn signals, and backup camera continued operating. The instrument clusters remained black, except for the odometer reading of 48,787 miles and the illumination adjustment graphic, which appeared when operating the brightness control. The odometer remain frozen despite additional driving. Multiple engine shut downs and restarts did not restore operation. The navigation system had also been generating erroneous wrong way warnings, occasionally positioning the vehicle in the opposing lanes on divided highways. These errors became more frequent following the instrument cluster failure. On XXX, Bridgewater Kia in [XXX] inspected the vehicle (invoice XXX). The technician performed a hard reset/capacitor discharge by disconnecting the battery. The system resume functioning and the odometer advanced from 48,787 to 48,789 during a 2 mile road test. Mileage driven during the malfunction, apparently was not recorded. The dealership did not identify the underlying cause. The service advisor acknowledge encountering similar failures in other 2024 Tellurides, although reportedly infrequently. I am concerned that the simultaneous lost of essential vehicle instrumentation and safety related warning systems could occur without warning. The dealership restored operation but did not identify or permanently correct the underlying defect. I request that the federal safety agency investigate this potential safety – related electronic failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On September 4, 2026, my son was driving our 2021 Kia Telluride on the highway at approximately 70 mph with cruise control engaged when the vehicle suddenly began making a clicking noise, followed by a catastrophic engine failure. We observed no oil-pressure warning or other advance dashboard warning before the failure. The sudden failure at highway speed created a significant safety risk. I am the original owner. The vehicle had approximately 115,000 miles at the time of failure. Its most recent oil change was performed on June 4, 2026, at 112,613 miles, approximately 2,400 miles before the incident. The servicing Kia dealership reported that the engine had a hole in it and essentially no oil remaining. The oil filter and drain plug were in place, and the dealership reported no external oil leak that explained the missing oil. An oil-filter-housing leak had previously been repaired in January 2026. The cause of the oil loss and engine failure has not been conclusively established. I am concerned about possible excessive internal oil consumption and the absence of an advance warning before catastrophic failure. I request that the federal safety agency investigate whether this condition affects other Tellurides and creates a risk of sudden engine failure or loss of propulsion at highway speed. Kia denied my initial request for goodwill repair assistance. The case has been escalated, but remains unresolved. The vehicle and failed engine are available for inspection through the servicing dealership.

My 2023 Kia Telluride has been subject to at least 8 separate the federal safety agency recalls, including SC181 (seat belt/child restraint), SC194 (trailer brake light/cruise control), SC207 (airbag OCS/ODS), SC262 (side airbag wire harness), SC303 (driveshaft/rollaway risk), SC316 (power seat motor fire risk), SC347 (door trim detachment), and now SC374/the federal safety agency 26V430 (recurrence of the power seat motor fire risk, explicitly noted as possibly caused by an improper repair under the earlier SC316 recall). I am especially concerned that the current recall (26V430) describes the same underlying defect as an earlier recall (SC316/24V407) that was supposed to have been repaired, and that no remedy is yet available for this recurrence. This raises serious questions about the adequacy of the original repair and the vehicle’s ongoing fire risk. I am filing this complaint to document this pattern of recurring safety defects and request that the federal safety agency and Kia treat this as evidence of an unresolved, recurring hazard — not an isolated incident.

My vehicle was purchased XXX - VIN #[XXX] - on 6 or more occasions, the while driving on the highway with cruise control on at 70 mph, the cruise control feature suddenly applied the brakes bringing the vehicle sometimes down to 48 mph for a few seconds and then re-engages the cruise control to 70 mph. This happens with no obsticals, vehicles, or other interference in front, however, there have been vehicles behind and this is a huge safety issue as it could cause a rear-end collision. My vehicle had been returned to the dealer, the first time for a week, they could not duplicate the issue, the vehicle was returned to me. On XXX I brought my vehicle again to the dealership for the same reason as the cruise control continues to disengages for no reason. The dealership has finally been able to duplicate the issue. The dealership still has my vehicle, not for 34 consecutive days. Kia tech line has been involved and now reports that it is not Kia's issue and they have denied fixing the vehicle and indicate that it a 3rd party issue referring to satellite and internet issues. The dealership has now disabled the satellite connection feature and wants me to try the car out to see if the issue continues.

While braking in slow traffic at about 11-15 mph, the vehicle hit a pothole/road irregularity and the ABS appeared to activate. The brake pedal vibrated, but the steering wheel also began shaking rapidly left and right. Braking effectiveness was greatly reduced. Even with firm brake pressure, the vehicle did not slow as expected and continued toward stopped traffic ahead. The brake pedal pushed back against my foot. I tried to steer around the vehicle in front of me, but the steering wheel vibration interfered with my steering input and made the vehicle difficult to control. A rear-end collision was avoided only after I shifted the transmission into Park, which brought the vehicle to a stop. All driver assistance systems were off, including adaptive cruise, lane keeping, highway driving assist, and steering assist. This occurred during normal low-speed braking, not aggressive or high-speed driving. I have had similar but less severe ABS behavior before when braking over potholes, bridge joints, or rough pavement, with excessive ABS activation and reduced braking performance. Dashcam footage is available showing the pothole/road irregularity, vehicle speed, steering/hand vibration, my avoidance attempt, and the near-collision. This appears to involve unexpected ABS activation, reduced braking effectiveness, and steering interference during routine low-speed braking, creating a serious safety hazard.

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)

On at least 3 occasions in the past nine months, when the cruise control was ON, the adaptive cruise control feature suddenly applied the brakes on our 2025 Kia Telluride. The last incident happened in May when there was NO vehicle in front of or on either side of our vehicle. Another time the brakes were suddenly applied while attempting to pass a vehicle at about 70 mph. As soon as our vehicle entered the passing lane, the brakes suddenly slowed our vehicle down to 45-50 mph, almost causing a rear end collision with another vehicle approaching our vehicle in the passing lane at a high speed. This only happens when the vehicle is in the cruise control mode and we ARE NOT applying the brakes. The vehicle is available for inspection upon request. The dealer was NOT able to reproduce the problem. We reported this to Kia Customer Care - Case #XXX on or about Feb. 21, 2026. Customer care orally responded to our report, denying any software or design problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am submitting this complaint regarding my 2021 Kia Telluride experiencing repeated and dangerous electronic system failures while driving. Kia of East Syracuse (NY) diagnosed the issue as related to the backup camera assembly and communication/network failures. While driving, the vehicle experienced loss of power steering assist, instrument cluster failure, speedometer malfunction, incorrect gear indication, backup camera activation while driving forward, blind spot warnings activating incorrectly, flashing/blank temperature display, and multiple driver assistance system failures. The speedometer displayed 0 mph while the vehicle was in motion and later displayed approximately 40 mph while stopped at a traffic light. The vehicle also became stuck in reverse while backing out of my driveway and would not shift properly, leaving the vehicle stopped in the roadway. Multiple safety systems malfunctioned simultaneously, including Blind Spot Collision Avoidance Assist, Lane Following Assist, Rear Cross Traffic Collision Avoidance Assist, Smart Cruise Control, Parking Distance Warning, and Forward Collision Warning systems. The dealership documented multiple fault codes and stated the dashboard lit up “like a Christmas tree” while the instrument cluster stopped functioning entirely. These failures create a serious safety risk because critical driving information and driver assistance systems become unreliable or inoperative while the vehicle is moving. The failures occur unexpectedly and without warning. Photos and video evidence have been retained, including video of the backup camera activating while driving forward and the speedometer malfunctioning while the vehicle was in motion. I am asking the federal safety agency investigate these failures as a potential safety defect involving the camera system, instrument cluster communication systems, and CAN network communication failures in the Kia Telluride.

While driving on the highway under normal conditions (clear weather, no nearby vehicles within approximately 1,000 feet), I heard a sudden loud “bang,” immediately followed by a large crack forming across the windshield. There was no visible debris impact, and no external cause could be identified at the time. Based on similar reports involving this issue in other vehicles, this appears to be a potential structural or manufacturing defect rather than road damage. While using adaptive cruise control in clear weather and with no traffic present, the vehicle will randomly decelerate as if detecting a vehicle ahead when none exists. This results in sudden, unnecessary braking without warning or indication. The issue has occurred multiple times and creates a significant safety risk, particularly at highway speeds where unexpected deceleration could lead to a rear-end collision.

While driving at highway speed and the adaptive cruise control engaged, the vehicle applied the brakes without driver input. The vehicle slowed gradually over several seconds even though there was no vehicle, pedestrian, or obstacle present in front of the vehicle. Road and environmental conditions were clear and normal, including clear weather, dry roadway, and unobstructed lane of travel. Traffic was flowing normally, and there was no lead vehicle. The driver was attentive and did not press the brake pedal. The braking occurred without any warning, alert, or collision indication and resulted in an unexpected reduction in speed, creating a risk of a rear-end collision from following traffic and on one occasion road rage (which has occurred due to this condition) as the driver thought I "brake checked" him. The vehicle has been inspected by the local Kia dealership (Spitzer Kia of Mansfield) and they could not replicate the condition. Kia has also been notified and a case number assigned (25773402) but with no resolution. This issue has occurred multiple times under similar highway driving conditions, indicating repeatable uncommanded braking behavior. Additionally, KIA issued a “Voluntary Service Campaign” for 2024 Kia Telluride’s on July 31, 2025 for the same vehicle behavior. Unexpected braking at highway speeds creates sudden speed differentials and increases the risk of rear-end collisions, even when deceleration is gradual. The driver has limited ability to anticipate or prevent the event. No warning lights, audible alerts, or collision warnings were displayed. CONCLUSION The vehicle exhibits repeatable false or uncommanded activation of the automatic braking system during highway driving, consistent with a potential defect in the AEB/FCA system. This condition poses a safety risk to vehicle occupants and surrounding traffic and should be reviewed by the federal safety agency
