2006 Kia Sedona suspension problems

Front and rear lower control arms corrode from the inside out and fracture suddenly under normal driving loads. Failures occur at low and highway speeds, often after previous repair attempts or dealer inspections that missed advancing corrosion. Some owners report arms breaking just over a year after recall service in which only a rustproofing coating was applied. The fracture typically results in immediate loss of steering control, wheel misalignment, and vehicle immobilization.

When: Variable; ranging from 76,450 miles to 170,000 miles; often 1–12 months after recall service

Symptoms owners cite: Loud crack, bang, or clunk from front or rear suspension; Vehicle pulls sharply to left or right; Loss of steering control or steering wheel seizes; Front or rear end drops or collapses; Wheel splays outward or inward; Vehicle stops abruptly mid-drive; Tire is punctured or pushed into fender by broken arm

Codes mentioned: Corrosion of control arm detected on inspection, Control arm fractured or broken in half, Excessive rust through-and-through on arm

Repairs/costs cited: Owners cite costs ranging from $300–$1,000+ for arm replacement; some paid out-of-pocket because dealers denied warranty coverage citing VIN exclusions from recall letters, or because recall was deemed 'inspection only' and parts were 'fine' at time of service. One owner paid $500 for repair after dealer found major cracks during alignment five months after previous dealer inspection found no defects.

Recalls/TSBs owners mention: 2013 recall (NHTSA 13V550000) authorized inspection and rustproofing; did not replace arms. 2016 recall (16V387000) authorized replacement in select states but excluded many VINs and was limited to 12-month warranty on replacement parts. Dealers have invoked VIN exclusions and state boundaries to deny service. Manufacturers initially claimed problem was resolved; some owners forced to sign legal waivers to receive reimbursement. Replacement parts unavailable in many regions; estimated remedy timeframe exceeded reasonable limits.

Sway bar end links corrode and the ball joints rust out of their sockets, allowing the sway bar to separate and strike the tire or suspension components. Failures occur over uneven surfaces and can happen repeatedly after replacement. One failure caused the sway bar to rupture the tire and drop the vehicle; another customer had links replaced twice (at 25,138 miles and 41,971 miles). Corrosion is extensive even on garaged vehicles.

When: As early as 25,000 miles; recurring within 16,000–17,000 miles of replacement

Symptoms owners cite: Loud clunking from front end over bumpy roads; Ball joints completely rusted out of sockets; Sway bar protrudes into or ruptures tire; Vehicle drops suddenly on one side; Rattling or clanking under vehicle over uneven surfaces; Shimmy in front end

Codes mentioned: Sway bar end link failed, Ball joint corrosion and separation, Sway bar obstruction of tire

Repairs/costs cited: Owners paid for replacement at 25,138 miles and again at 41,971 miles; tire replacement also required when sway bar punctured it. One owner had right and left sway bar links replaced on multiple occasions by both dealer and independent shop.

Recalls/TSBs owners mention: No specific recall identified in narratives for sway bar link corrosion. One owner contacted Kia regarding failed sway bar link damage (tire and sway bar) and was told the parts would not be covered under the lower control arm recall. Manufacturer response not yet received at time of complaint filing.

Front coil springs corrode and fracture, sometimes shedding metal pieces. One spring broke while vehicle was parked, releasing an 8-inch piece of metal that later punctured the tire. Springs fail from salt and water corrosion on the finish. A 2013 recall (NHTSA 13V550000) was issued in 21 states but had a production-date cutoff (December 2005 to March 20, 2012). One owner's 2006 Sedona manufactured April 18, 2012 was excluded despite identical failure mode; the owner was told the issue had been 'resolved.' Another owner's spring broke while driving and caused a loud noise and vibration.

When: Variable; one at parked condition; another at highway speeds; one at 116,576 miles (right rear broke two days later)

Symptoms owners cite: Loud clunk or crack while parked or driving; Metal fragment on ground beneath vehicle; Loud noise while driving at highway speeds; Vibration from suspension; Spring piece punctures tire (flap visible on tire sidewall); Second spring breaks shortly after first (observed in one case)

Codes mentioned: Coil spring fractured, Corrosion on spring finish, Spring material separated

Repairs/costs cited: One owner paid for tire replacement (in addition to spring) caused by puncture from broken spring fragment. Another owner replaced both front springs at their own expense because VIN was outside recall date range. One owner paid $500 for front spring replacement; another had both front and rear springs replaced in April 2015.

Recalls/TSBs owners mention: 2013 recall (NHTSA 13V550000) issued in 21 states for vehicles manufactured December 2005 to March 20, 2012. Dealer told one owner the recall 'covered vehicles made from December 2005 to March 20, 2012. My van was made on April 18, 2012, and therefore was not covered by the recall because the issue had been resolved.' Owner disputed this, asking why the spring broke if the issue was resolved. No extended remedy offered.

Vehicle exhibits loud clunking or rattling over uneven surfaces—including potholes, gravel, and bumpy roads—that multiple ASE-certified mechanics could not pinpoint despite extensive inspection. One owner replaced struts, bushings, CV boots, and had three ASE mechanics inspect simultaneously, checking for loose or broken parts, including spare tire pressure. Noise feels as well as sounds; all passengers can feel it. It occurs randomly on uneven surfaces but cannot be reproduced on speed bumps. Appears to originate around spare tire area but is felt throughout the cabin.

When: After one year of ownership; ongoing at nearly 100,000 miles

Symptoms owners cite: Loud clunking or rattling sound over uneven surfaces; Vibration felt throughout cabin and under driver/passenger areas; Occurs randomly; not reproducible on command; Worse over potholes and gravel; not triggered by speed bumps; Cannot be pinpointed despite multiple inspections

Repairs/costs cited: Owner replaced struts, bushings, CV boots, and other suspension items; cannot identify root cause. Multiple independent inspections performed; three ASE-certified technicians inspected together without finding the source.

Vehicle pulls strongly to the left on freeway and during normal driving, requiring constant steering correction. Private mechanic alignment and three dealer visits including strut replacement and adjustment have not resolved the issue. Dealer mechanics attributed the pull to road slope and torque-steering as 'normal,' but owner found multiple online complaints of identical problem on 2006 Sedonas. The pull worsens over time and makes long drives fatiguing and dangerous.

When: Began March 2007; worsened over two months prior to complaint

Symptoms owners cite: Vehicle pulls sharply to left on freeway and city streets; Veers toward median if steering wheel is released; Driver arms and hands tire from constant correction; Pull worsens over time; Occurs at all speeds

Repairs/costs cited: Owner paid for private mechanic alignment; three dealer visits included adjustment (first visit, no charge), right-side strut replacement (second visit, no charge), left-side strut adjustment (third visit, no charge). Fourth visit scheduled for left strut replacement with no assurance of resolution.

Recalls/TSBs owners mention: Dealer made excuses citing road slope and torque-steering as normal. Dealer was unaware of widespread complaint pattern. Owner initiated Wisconsin lemon-law process (four repairs for same issue in first year qualifies vehicle as lemon).

Engine RPMs race while vehicle fails to accelerate; requires release and reapplication of throttle to engage. Occurs rarely (5–6 times) and suddenly, often during highway on-ramps or when accelerating from a stop. Feels like transmission is slipping but dealer service found no issue and could not reproduce the problem.

When: Sporadic; between 76,450 and 100,000 miles

Symptoms owners cite: Engine races (high RPMs) but vehicle does not accelerate; Sudden hesitation on acceleration; Requires driver to lift off gas and reapply to engage transmission; Happens suddenly and infrequently; Occurred twice when owner almost got rear-ended due to unexpected loss of power

Repairs/costs cited: Dealer service found no issue at time of inspection and could not reproduce the problem.

Cruise control fails to decelerate when descending hills or slight grades. Vehicle accelerates past set speed (e.g., from 40 mph to over 60 mph) requiring brake application. Dealer claimed this is normal. One owner reported involuntary engagement of cruise control at 15 mph after recall service, accompanied by loud buzzing from dash.

When: Ongoing; one incident at 89,000 miles after brake-switch recall service

Symptoms owners cite: Cruise control does not decelerate on downhill grades; Vehicle accelerates past set speed limit; Involuntary engagement of cruise control; Loud buzzing from dash area; Intermittent occurrence

Repairs/costs cited: No repairs documented; dealer stated behavior is normal.

Recalls/TSBs owners mention: Dealer stated acceleration on grades is normal behavior; no recall or service procedure offered.

Front control arm mount at subframe corrodes and breaks, causing steering and suspension malfunction. One owner reported the control arm mount at subframe broke while driving, nearly causing loss of control and head-on collision. Vehicle became difficult to steer until speed was reduced. This is distinct from lower control arm failure and appears to be a separate corrosion issue not addressed by existing recalls.

When: Unknown mileage

Symptoms owners cite: Loud noise or bang from suspension; Sudden steering malfunction; Near loss of control; Vehicle becomes hard to steer

Codes mentioned: Control arm mount at subframe broken due to rust

Recalls/TSBs owners mention: Dealer confirmed Kia has a known recall for lower control arm rusting but nothing for subframe rusting/breaking. Owner states this issue should be addressed but no manufacturer response documented.

Front and rear subframe bushings corrode and must be replaced. One owner reported squealing at low speed (5 mph) from front passenger side bushings. Dealer stated they would not replace bushings until they fractured and could not be pressed out without damaging the subframe. Owner had right-side subframe bushings replaced at 32,268 miles and left-side rear subframe bushings at 33,367 miles.

When: 24,400 miles (squealing detected); prior replacements at 32,268 and 33,367 miles

Symptoms owners cite: Abnormal squealing from subframe bushings; Occurs at low speeds; Bushings begin to fail without warning

Repairs/costs cited: Dealer refused to replace bushings until fractured; owner had to wait for failure. Right-side bushings replaced at 32,268 miles; left-side rear bushings replaced at 33,367 miles.

Recalls/TSBs owners mention: Dealer informed owner that bushings could not be replaced until fractured, as fractured bushings cannot be pressed out without causing damage to subframe.
