Owners of the 2012 Ford Explorer consistently report suspension failures across multiple components. Rear toe link wear is the most documented problem, covered by NHTSA Campaign 21V746000, but owners encounter months-long delays waiting for parts availability. When repairs do get done, failures recur—one owner reports the dealer falsely claiming repair completion when work was never performed.
Strut mount separation appears in multiple independent reports, with one owner noting five vehicles of the same year and model requiring strut mount replacement within six months in a small community. Noises during turns and bumps precede failures, and some owners struggle finding replacement parts due to frequency of the issue.
Rear suspension geometry problems cause severe tire wear and unsafe handling in wet conditions despite normal alignment readings. Several owners report snapping lateral links and fractured axle mounts, particularly at the passenger side. One critical failure involved subframe corrosion causing structural separation and wheel drift at highway speed.
Parts availability remains a recurring frustration. Two owners waiting on Campaign 19V435000 and 24V031000 repairs report dealers confirming parts are not yet available at 156,000 miles. Owners consistently state manufacturers claim parts unavailable or exclude their VINs from coverage despite similar failures on identical model years.
Failure modes owners describe
Rear toe links wear/failure
Rear toe links deteriorate and require replacement, causing alignment drift and handling issues. NHTSA Campaign 21V746000 addresses this issue, though owners report parts availability delays and repeat failures.
When: 100,000 miles and beyond
Symptoms owners cite: hard pull to the right during acceleration; recurring failure after dealer service
Repairs/costs cited: Rear toe links replaced per recall; owners report parts backorders delaying repair for extended periods
Recalls/TSBs owners mention: NHTSA Campaign 21V746000 (Suspension)
Subframe corrosion and fracture
Front subframe corrodes and fractures, allowing wheels to shift outward. This is a structural failure that impacts steering stability and safety.
When: 139,000 miles
Symptoms owners cite: abnormal snapping then clunking sound from underneath; traction control and ABS lights illuminate; wheels pushed outwards in opposite directions
Repairs/costs cited: Front subframe replaced by certified mechanic
Strut mount failure
Upper strut mounts deteriorate or separate from vehicle body, producing noise during turns and bumps. Multiple owners in same geographic area report failures within short timeframes, suggesting systemic issue.
When: Various; one report at 55,000 miles
Symptoms owners cite: horrible noise when turning or hitting bumps; possible separation of strut mount from vehicle; clunking from strut bearings
Codes mentioned: wrench icon, service advance track indicator, cross traffic system fault indicator illuminate after repair
Repairs/costs cited: Both strut mounts replaced; parts difficult to locate due to frequent need; one case required vehicle reprogramming after replacement
Rear axle mount fracture
Passenger-side axle mount fractures, causing grinding metal sound and loss of gear engagement. Replacement resolves immediate failure but may trigger warning light issues.
When: 74,000 miles
Symptoms owners cite: grinding metal sound while driving at low speed; vehicle stops and will not engage gear; multiple warning lights illuminate after repair
Codes mentioned: wrench icon, service advance track indicator, cross traffic system fault indicator
Repairs/costs cited: Passenger side axle mount replaced; vehicle required dealer reprogramming for warning light codes
Rear suspension alignment and tire wear
Rear suspension exhibits alignment issues causing abnormal tire wear and unsafe handling in wet conditions. Tires rub on suspension components and wear prematurely despite no standard alignment adjustments.
When: 198,000 miles (one report); general pattern reported
Symptoms owners cite: rear tires rubbing on interior of vehicle; extremely fast tire wear; vehicle unstable in rain, slides; check warning light illuminated
Repairs/costs cited: Tires replaced; aftermarket adjustable components available but original design is non-adjustable
Rear lateral link failure
Upper rear lateral links snap off the vehicle, causing loss of rear suspension control. Owner reports three separate failures (two driver side, one passenger side) in single vehicle.
When: Mileage not specified
Symptoms owners cite: rear lateral links snap off; rear tire steering uncontrollably; owner expresses fear about driving
Repairs/costs cited: Links replaced; pattern suggests recurring failure
Recalls/TSBs owners mention: Owner notes recall exists for rear toe links; believes lateral link failure may be same root cause
Recall parts availability delays
Multiple owners encounter extended delays obtaining parts for suspension recalls (Campaigns 19V435000 and 24V031000). Dealers cannot perform recall work while waiting for parts, leaving vehicles unsafe for indefinite periods.
When: Reported at 140,000-156,000 miles
Symptoms owners cite: unable to complete recall repairs; manufacturer states parts not available; delays exceed reasonable timeframe
Repairs/costs cited: No repairs completed; parts remain on backorder
Recalls/TSBs owners mention: NHTSA Campaign 19V435000 (Suspension), NHTSA Campaign 24V031000 (Structure); parts distribution disconnect confirmed for Campaign 19V435000
Power transfer unit leak
Power transfer unit develops leak requiring replacement. Occurred in vehicle previously repaired under recall, suggesting either recall repair was ineffective or separate component failure.
When: 140,000 miles; two weeks after recall suspension repair
Symptoms owners cite: power transfer unit leaking
Repairs/costs cited: Power transfer unit needed replacement
Recalls/TSBs owners mention: Manufacturer stated VIN not included in recall; repair not covered
