The 2015 Ford Explorer has a pronounced rear suspension defect centered on the toe link and its underlying support structure. Owners describe sudden loss of vehicle control during turns or on uneven roads, with the rear end swaying or fishtailing violently at any speed from 5 to 70 MPH. Multiple owners report the toe link fractured without warning after recall repairs, in some cases within days, causing the vehicle to swerve across multiple lanes or into curbs and guardrails.
The root cause appears to involve corrosion of cross-axis ball joints and knuckle bushings—Ford's 2019 recall even mentioned that road salt in northern climates accelerates this failure mode—but replacement toe links installed during recall repairs are non-adjustable by design. Alignment shops confirm the rear wheels cannot be properly corrected after these repairs, leaving owners with abnormal tire wear and handling problems. Some toe links have fractured twice despite replacements.
Ford's response has been inconsistent: the manufacturer has issued multiple recalls (2019, 2021) but claims recalls are one-time repairs and denies warranty coverage on recurrent failures. Owners also report inability to complete recalls because dealers are unable to obtain replacement parts, with timelines stretching months or years. One owner lost complete front suspension at 60 MPH; another had their power steering fail entirely. Dealerships refuse to take responsibility, and Ford has repeatedly deferred owners to the NHTSA hotline rather than providing remedies.
Failure modes owners describe
Rear toe link fracture
Rear toe link breaks or fractures, causing loss of rear-end control and unpredictable handling. Owners report the vehicle swerving, fishtailing, or swaying violently at highway and low speeds. Multiple fractures have recurred after recall repairs, suggesting a systematic defect. Failures occur with and without warning.
When: 50,000 to 141,000 miles; failures reported 4 days to years after recall repairs
Symptoms owners cite: Loss of vehicle control during turns or on uneven roads; Fishtailing or swaying at speeds 5–70 MPH; Clunking or metal-striking-metal sound from rear; Rear wheels wobbling or leaning into wheel wells; Rear tires abnormally worn or shredded; Vehicle pulling or misaligned
Repairs/costs cited: Replacement rear toe links; reinforced versions cited in at least one case; some shops note parts lack adjustability for proper alignment
Recalls/TSBs owners mention: NHTSA Campaigns 19V435000 (2019) and 21V537000 (2021) for rear toe link/cross-axis ball joint inspection and replacement; Campaign 16V245000 (2016) for rear subframe. Ford refused warranty coverage on repeat failures post-recall, citing one-time repair provision. Multiple owners report Ford denied responsibility or referred them to NHTSA hotline.
Front suspension collapse or control arm fracture
Front suspension components fail suddenly, causing the front end to collapse or drop to ground level. Loss of steering control and inability to maneuver ensue. One owner lost steering entirely at 60 MPH, resulting in collision with concrete barriers; another at low speed during a turn. Both events caused loss of control with minimal or no airbag deployment.
When: 50,000 to 80,000 miles
Symptoms owners cite: Front suspension on ground after failure; Sudden loss of steering control; Vehicle veering to one side uncontrollably; No warning lights or advance indication
Repairs/costs cited: Independent mechanic diagnosed and repaired front suspension and control arms on one vehicle; another was totaled and not repaired
Recalls/TSBs owners mention: Ford refused to take responsibility for repair costs; dealership did not diagnose or authorize repair in one case; no manufacturer-initiated response documented
Knuckle and bushing degradation leading to toe link fracture
Knuckle bushings and related rear-end components wear or corrode, creating excessive play and stress concentration on rear toe links. Corrosion accelerated by road salt in northern climates. Once bushings fail, toe links fracture prematurely, even after replacement. One owner reports Ford dealership acknowledged the root cause (knuckle and bushings) but refused coverage, citing recall parts as final repair.
When: 70,000 to 130,000 miles; corrosion accelerated in northern/salt-exposed vehicles
Symptoms owners cite: Wobbling noise from rear; Rear-end instability when braking or accelerating; Toe link fracture recurrence after replacement; Rusted or degraded rear suspension components
Repairs/costs cited: Knuckle bushing replacement noted in at least one post-recall repair; cross-axis ball joint replacement and reinforced toe links used; full cost of knuckle/bushing repair ($2,411) denied by Ford in one case
Recalls/TSBs owners mention: NHTSA Campaign 21S32 (2019) identified corrosion risk in northern/salt environments; Ford refused warranty on secondary repairs, claiming recall satisfied obligation. No TSB or extended coverage program documented.
Non-adjustable rear toe link preventing alignment
Replacement rear toe links installed during recall repairs lack adjustment mechanisms, making proper wheel alignment impossible. Tire dealers and independent shops confirm rear toe cannot be adjusted after recall repair. This design flaw results in abnormal tire wear and handling problems persisting indefinitely after repair.
When: Post-recall repair; becomes apparent during or after routine alignment work
Symptoms owners cite: Alignment shop unable to correct rear wheel alignment; Abnormal or excessive tire wear after recall repair; Vehicle pulling or handling issues persist; Rear tires wearing on edges despite replacement toe links
Repairs/costs cited: No repair available; owners and shops note the replacement parts are fixed and non-adjustable by design
Recalls/TSBs owners mention: No acknowledgment of design flaw; dealers confirmed no further correction possible after recall repair
Wheel hub bearing assembly failure
Wheel hub bearing assemblies fail prematurely, resulting in wheel separation risk. One complaint references NHTSA recall regarding hub bearings incorrectly listed for 2011–2017 Explorers, manufactured without self-retention feature.
When: Approximately 85,000–100,000 miles
Symptoms owners cite: Rear hub bearing failure; Wheel separation risk
Repairs/costs cited: Part Number HB5Z-1104-C noted as defective; repair involved hub bearing replacement
Recalls/TSBs owners mention: NHTSA recall issued addressing incorrect part application; one owner's repair covered under warranty after recall announcement
Power steering failure
Power steering system fails suddenly, forcing operator to manually steer the vehicle with extreme effort. Two separate incidents reported: one where steering locked up and required violent force to regain control; another where steering failed entirely during low-speed suburban driving.
When: Approximately 85,000 miles; mid-range mileage vehicle
Symptoms owners cite: Loss of power steering assistance; Steering becomes extremely difficult to turn; Steering locks or binds; loud bang when binding releases; No warning lights prior to failure
Repairs/costs cited: Power steering rack replacement; repair costs cited as $2,107.00 (two separate cases with identical cost)
Recalls/TSBs owners mention: No manufacturer response or warranty coverage documented; costs borne entirely by owner
Steering rack stiffness and binding
Steering exhibits chronic popping noises and occasional locking or binding, restricting steering rotation to approximately 30 degrees. Owners report this mirrors a mass recall on earlier model years (pre-2015) but the defect persists on 2015 models without recall coverage.
When: Unknown mileage; reported as ongoing issue
Symptoms owners cite: Constant popping noises from steering column; Occasional steering binding or locking; Steering rotation restricted to ~30 degrees; Loud bang when binding releases
Repairs/costs cited: No repair performed; dealership suspected steering rack replacement needed (same fix as prior-year recall)
Recalls/TSBs owners mention: No recall issued for 2015 model despite similar failures on earlier years; dealership acknowledged likely cause but no warranty remedy offered
Recall part supply delays and unavailability
Multiple suspension recall campaigns (19V435000, 20V675000, 21V537000) issued but parts remain unavailable for extended periods or indefinitely. Owners are notified of safety-critical recalls but cannot schedule repairs because parts are not in stock. Some dealers provide no timeline; others suggest waiting months or years. At least one owner reports recall notice marked as safety-critical while being told to check back next year.
When: Recurring issue from 2020–2024; complaints submitted years after recall issue dates
Symptoms owners cite: Recall notification received but parts unavailable at dealership; Manufacturer unable to confirm availability timeline; Owners asked to repeatedly call back or rescheduled multiple times; Parts listed as 'not available' in dealer systems
Repairs/costs cited: No repairs completed; parts distribution disconnect identified by multiple complaints
Recalls/TSBs owners mention: NHTSA Campaigns 19V435000 and 20V675000 issued; Ford and dealers confirm parts unavailable; no loaner vehicle provisions offered; no compensation or expedited timeline provided
