Owners of 2007 Kia Sedonas describe multiple suspension failures, most commonly broken front coil springs and fractured lower control arms. The coil spring breaks occur across a range of mileage—from 54,000 miles to well over 100,000—often triggered by normal driving over bumps or potholes. Some owners report that a 2006 model recall (SC-095) for this exact issue appears applicable to 2007 models, yet Kia limited the recall to 2006 only. Lower control arm fractures lead to severe incidents: wheels detaching at 15 mph, sudden loss of steering control, and vehicle collapse while driving 30 mph. Corrosion is cited as a root cause in at least one case. Owners also report persistent bushing wear requiring premature replacement ($2,200 for sub-frame bushings at 62,000 miles), with control arm and sway bar link bushings failing shortly after. Front strut and strut mount corrosion appears at 50,000 miles. A small number of complaints mention squeaking tie rods and steering noises that dealers cannot diagnose or repair. One report links a recall repair (control arm) to subsequent ball joint loosening from grease leakage. The narratives indicate that recall parts have been unavailable and some vehicles remain unrepaired despite notification to the manufacturer.
Failure modes owners describe
Front coil spring fracture
Right front and/or left front coil springs break during normal driving, often over bumps or potholes. Occurs at mileages ranging from 54,000 to over 100,000 miles.
When: 54,000–100,000+ miles; 2006 model recall (SC-095) applied only to models produced Dec 20, 2005–March 20, 2006, but owners report same issue in 2007 models produced later in 2006
Symptoms owners cite: Loud bang or noise when hitting bumps or potholes; Vehicle collapse on front driver's side while driving at 30 mph; Visible broken spring upon inspection; Potential catastrophic failure risk under sudden stops or evasive maneuvers
Repairs/costs cited: Coil spring replacement; recall parts availability issues noted
Recalls/TSBs owners mention: 2006 model recall SC-095 issued for this specific issue; Kia stated recall applicable to 2006 only despite similar conditions in 2007 models
Front lower control arm fracture
Lower control arms fracture or fail, sometimes due to corrosion. Results in loss of steering control, wheel detachment, or vehicle immobilization.
When: 79,183–155,000 miles; some failures preceded by recall repairs (NHTSA campaign 13V550000)
Symptoms owners cite: Snap or cracking noise under the vehicle while driving; Steering wheel jerks or pulls left/right independently; Front driver-side tire bends forward or wheel detaches; Loud scraping noise from underneath; Vehicle seizes and must be pushed off roadway
Codes mentioned: NHTSA campaign 16V387000 (Suspension), NHTSA campaign 13V550000 (Suspension)
Repairs/costs cited: Front lower control arms require replacement; fracture of axle shaft and sway bars also noted in one case; racket pinion found busted in another
Recalls/TSBs owners mention: Campaign 16V387000 issued; one vehicle previously repaired per campaign 13V550000 failed again at 133,000 miles; recall parts reported unavailable; some vehicles not repaired despite manufacturer notification
Front ball joint fracture
Ball joints fracture, sometimes in conjunction with axle failure. Leads to sudden loss of vehicle control.
When: 79,183 miles
Symptoms owners cite: Violent shaking while driving at 35 mph; Vehicle stops abruptly without warning; Visible fracture of ball joint upon inspection
Codes mentioned: NHTSA campaigns 13V550000 and 16V387000 did not cover this VIN
Repairs/costs cited: Ball joint and axle replacement required
Sub-frame and control arm bushing degradation
Front sub-frame cross-member bushings and control arm bushings wear prematurely, causing noise over bumps. Sway bar link bushings fail shortly after sub-frame bushing replacement.
When: 62,000 miles (sub-frame bushings); 67,000 miles (control arm bushings)
Symptoms owners cite: Noise from suspension over bumps; New front-end noises develop shortly after repair
Repairs/costs cited: Front sub-frame cross-member bushings replacement: $2,200; control arm bushings and sway bar link bushings subsequently require replacement
Front strut and strut mount bearing corrosion
Front struts, strut mount bearings, and bearing plates develop corrosion, causing noise when steering.
When: 50,000 miles
Symptoms owners cite: Abnormal cracking noise when turning steering wheel at 40 mph
Repairs/costs cited: Front struts, strut mount bearings, and bearing plates require replacement
Tie rod wear and noise
Tie rods produce squeaking noise over bumps or dips; alignment issues develop due to worn tie rod ends.
When: 96,000 miles (persistent complaint since purchase in 2008)
Symptoms owners cite: Squeaking noise on every bump or dip; Axle or tie rod noise
Repairs/costs cited: New tie rods required for alignment; mechanics report 'nothing is wrong' despite repeated complaints
Post-recall control arm repair leading to ball joint loosening
After recall repair of control arm, grease leaks onto ball joints, causing them to loosen. Failure mode repeats or persists despite repair.
When: Approximately 75,000 miles
Symptoms owners cite: Ball joint loosening after control arm recall repair; Grease leakage onto ball joints
Repairs/costs cited: Recall work performed; issue not remedied
Recalls/TSBs owners mention: Recall work performed but failure not corrected; recall details not provided by owner
