Subaru Forester: Remote Smart Parking Assist malfunction and limitations / Limitations of Remote Smart Parking Assist

Under specific environmental, physical, or technical conditions, the performance of the Kia Telluride Remote Smart Parking Assist system during automated parking or exiting maneuvers may be restricted. In these circumstances, the risk of collision can increase or the automated feature may suddenly disengage without warning. Drivers must remain fully vigilant and park or exit the vehicle manually whenever necessary.

• Aftermarket steering wheel accessories, protective covers, or custom modifications have been applied to steering mechanisms and mechanical components.

• The vehicle is operating with snow chains attached, a temporary compact spare tire installed, or non-standard aftermarket wheel and tire dimensions fitted.

• Tire inflation levels deviate significantly from the recommended cold tire pressure specification indicated on the vehicle door jamb placard.

• Your Kia Telluride is carrying bulky cargo that extends beyond the vehicle width or length parameters, or an external trailer is attached to the towing harness.

• Suspension components have been altered, aftermarket lift kits installed, or the overall chassis wheel alignment is improperly calibrated.

• The vehicle chassis leans severely to one side due to uneven heavy cargo distribution or suspension strut damage.

• Your vehicle is actively equipped with an installed rear trailer hitch assembly that alters rear bumper clearances.

• The front or rear license plate is mounted loosely, offset, or positioned away from its factory original mounting location.

• A person, domestic animal, or physical object is positioned directly above or immediately below the ultrasonic sensor range when Remote Smart Parking Assist is activated.

• The selected parking bay features a curved perimeter, non-standard layout, or diagonal parking space markings.

• Physical hazards or movable obstacles, such as pedestrians, pets, trash receptacles, bicycles, motorcycles, shopping carts, or structural support pillars, are situated near the target parking stall.

• The parking space is adjacent to circular columns, narrow structural posts, or pillars obstructed by attached equipment such as fire extinguishers or utility boxes.

• The underlying road surface features steep vertical transitions, elevated curbs, speed bumps, or uneven pavement edges.

• Roadway traction is severely reduced by rain, mud, icy patches, wet leaves, or standing water.

• The target parking spot is situated directly alongside heavy commercial machinery, oversized buses, or high-ground-clearance vehicles like lifted pickup trucks.

• The designated parking space is situated on a steep incline or declined roadway grade.

• Severe crosswinds or intense gusty weather conditions interfere with vehicle trajectory control and ultrasonic signal reflection.

• Attempting to engage the Kia Telluride Remote Smart Parking Assist system on unpaved gravel paths, rutted off-road trails, thick vegetation, or overgrown grassy surfaces.

• Ultrasonic sensor hardware experience operational degradation due to extreme ambient heat waves or freezing sub-zero weather conditions.

• Ultrasonic sensor emitters embedded in the bumper covers are obscured by accumulated snow, ice, mud, road grime, or heavy rain droplets.

• External equipment generating high-frequency ultrasonic acoustic waves is functioning nearby and disrupting sensor feedback.

• High-powered wireless transmitters, radio frequency devices, or heavy signal emitters are broadcasting actively near the bumper sensor array.

• Your Kia Telluride proximity sensors experience signal interference from the active Parking Distance Warning radar or sonar emitted by neighboring vehicles.

• Sensors are misaligned, shifted out of position, or internally damaged following a minor bumper collision, curb impact, or parking incident.

• The system's ultrasonic sensors struggle to detect thin, narrow, or tapered obstacles such as wire ropes, steel chains, flexible fencing, or thin boundary posts.

• Obstacles measuring less than 40 inches (100 cm) in total length and under 6 inches (14 cm) in cross-sectional diameter fall below standard detection thresholds.

• Target obstacles composed of sound-absorbing materials, soft clothing, thick fabrics, porous sponges, or loose powdery snow reduce ultrasonic echo intensity.

• An accessory trailer hitch assembly installed on the rear bumper obstructs the rear sensor sweep angle.

The Kia Telluride Remote Smart Parking Assist feature may experience operational failures or unexpected disengagements under the specific scenarios outlined below:

Limitations	Details
	Always execute manual parking maneuvers when navigating sloped driveways or steep inclines, as gravity can compromise automated throttle and brake modulation.
	The automated Kia Telluride Remote Smart Parking Assist sequence may automatically cancel if wheel slip is detected or if terrain conditions like loose gravel, crushed stone, or severe rutting prevent smooth vehicle propulsion.
	Operating Remote Smart Parking Assist near elevated obstacles or protruding structural overhangs (such as raised truck cargo beds or wall-mounted equipment) presents a serious collision risk because bumper-level sensors cannot reliably detect high clearances. Always park or exit manually in these environments.
	System tracking accuracy degrades and collision risks increase when parking adjacent to narrow columns, round concrete support pillars, square posts, or pillars obstructed by attached items like fire extinguishers or hoses. Drivers should manually control the Kia Telluride in tight structural spaces.
	When attempting an automated maneuver into a stall bounded by a single vehicle on one side, the system may miscalculate lateral positioning and drift over painted boundary lines to maintain artificial clearance from the adjacent car.
	Accumulated snow or ice buildup can blind ultrasonic sensors, while slippery tire traction may cause the system to cancel active parking operations to prevent uncontrolled sliding.
	The Kia Telluride Remote Smart Parking Assist system is engineered strictly for parallel and perpendicular spaces and does not support diagonal parking layouts. Never attempt to use the feature in angled stalls, even if initial entry appears feasible.
