What stands out
Of the 12 model years of Toyota 4Runner we track for body problems, this one carries the most owner complaints on file — 138.
Body accounts for 33% of every owner complaint on file for this vehicle — the dominant problem area across 11 categories tracked.
The failure pattern owners describe
Buyer takeaway: Frame rust is a pervasive structural defect in 2005 4Runners, often undetectable until advanced corrosion causes suspension failure, brake line rupture, or loss of steering control—sometimes at highway speeds. Avoid this model year unless the frame has been professionally inspected and verified sound; even garage-kept examples with low miles develop holes and deterioration that Toyota refuses to address via recall or warranty.
Frame corrosion dominates complaints on the 2005 4Runner. Owners describe rust developing inside frame cavities, spreading unseen despite undercoating and garage storage, eventually creating visible holes, fractures, and complete loss of structural integrity. Front cross members rot almost completely through; trailing arm brackets become dangerously thin; suspension attachment points deteriorate. Rust emerges across a wide mileage range—some owners discover it at 74,000 miles, others push past 130,000 before serious symptoms surface.
The failure modes are severe. Brake lines corrode and fail mid-drive, forcing owners to coast to safety. Suspension components detach from the frame, causing loss of control and swerving across highway lanes. Steering wheels shake violently or become crooked after pothole impacts damage weakened frame structure. Multiple shop owners tell customers the frame is beyond safe repair; one mechanic said he'd never seen rust this extensive in thirty years on the job.
Toyota replaced frames on 2005–2010 Tacomas, 2005–2008 Sequoias, and 2007–2008 Tundras through class action settlements—but excluded 4Runners. Dealers confirm corrosion but refuse repairs, often declining even routine maintenance for fear of snapping bolts. Owners consistently report Toyota declining all recall, buyback, or warranty claims. Dashboard cracking is a secondary issue, appearing even on low-mileage garage-kept units, with replacement quoted at several thousand dollars.

Failure modes owners describe
Frame rust and corrosion
Extensive rust affecting frame structural integrity, including cross members, brackets, and suspension attachment points. Rust develops both on exterior surfaces and internally within frame cavities, progressing to holes, fractures, and complete deterioration in critical areas. Multiple owners report rust visible on underbody despite proper maintenance, garage storage, and undercoating applications.
When: Typically emerges between 74,000 and 205,000 miles; some owners notice symptoms as early as 82,000 miles, others after 130,000+ miles. Several owners report rust becoming visible or critical around 12–15 years of ownership.
Symptoms owners cite: Visible rust flaking and scaling on frame surfaces; Holes and gaps forming in frame (reported from 2–7 inches); Rust developing inside frame cavities, spreading unseen; Front cross member rotted almost completely through; Trailing arm brackets becoming thin and deteriorating; Frame components breaking under light stress (potholes, low-speed impacts); Loss of vehicle control or swerving at highway speeds when suspension components detach; Brake line failures secondary to frame corrosion; Steering wheel shaking and crooked alignment after frame damage; General inability to drive safely after frame inspection
Repairs/costs cited: Owners cite frame replacement as the only permanent repair, with labor costs often exceeding vehicle value. Several body shops refuse welding repairs due to Toyota technical guidance against frame welding and insurance liability. One owner estimated brake line replacement alone at $3,500; another described attempted frame swap labor that could exceed vehicle value when bolts snap due to corrosion.
Recalls/TSBs owners mention: Toyota declined all requests for recall, repair, or buyback for 2005 4Runner models. One owner received a $1,500 loyalty discount toward a new vehicle, which they rejected. Toyota technicians at dealerships confirmed frame corrosion but stated it posed 'no imminent threat' or offered no solution. Toyota replaced frames on 2005–2010 Tacomas, 2005–2008 Sequoias, and 2007–2008 Tundras via class action settlements, but explicitly excluded 4Runners from those campaigns.
Dashboard cracking
Cracks appearing in dashboard assembly, primarily along driver-side area near windshield and passenger compartment. Owners report multiple cracks spreading across dashboard surfaces in garage-kept vehicles with sun protection, suggesting material brittleness rather than impact damage.
When: Reported on vehicles as young as 39,000 miles; present on well-maintained, low-mileage examples stored indoors.
Symptoms owners cite: Single or multiple cracks visible in dash panel; Cracks forming in driver-side corner near windshield; Cracks appearing in areas between instrument cluster and radio; Cracks spreading over time despite protective measures (sun visor, garage storage); Cosmetic damage with potential safety concern if airbag deployment occurs near cracks
Repairs/costs cited: Toyota dealership quoted several thousand dollars for dashboard replacement. Most owners cannot afford replacement and defer repair or seek third-party solutions.
Recalls/TSBs owners mention: Toyota declines responsibility, stating vehicles are out of warranty and attributing cracks to owner neglect. No recall or service campaign exists. Owners note Toyota has upgraded dashboard material quality on newer model generations.
Unintended acceleration event
Vehicle accelerated rapidly when owner applied brakes while pulling into garage at very low speed, causing owner to crash through garage wall and sustain injuries.
When: Incident occurred during low-speed garage entry maneuver.
Symptoms owners cite: Brakes applied but vehicle accelerated instead of decelerating; Rapid uncontrolled acceleration despite foot on brake pedal; Airbags failed to deploy during collision
Spare tire lift cable failure
Spare tire cable assembly degraded and frayed, causing mechanism to jam. Cable was damaged by retraction mechanism; failure risk could drop spare tire onto roadway during highway driving.
When: Not specified.
Symptoms owners cite: Spare tire cable frayed and stuck; Cable severely damaged by retraction mechanism; Spare tire would not descend fully
Repairs/costs cited: Toyota quoted $250 for mechanism replacement. Owners describe it as poor design prone to recurrence.
Recalls/TSBs owners mention: Toyota has recalled similar mechanism on Sienna but refused to extend recall to 4Runner. No remedy offered.

The contact owns a 2005 Toyota 4Runner. The contact stated that the subframe was rusted. The TPMS warning light was illuminated. The vehicle was taken to an independent mechanic, who repaired the TPMS, but the failure persisted. The vehicle was taken to the local dealer, where it was diagnosed that the frame was rusted and recommended that the vehicle no longer be driven. The mechanic referred…
Lost end of muffler ("exhaust tip") while driving due to under body rust. The inspector also noted to me the high level of rust building up on the under body at the last safety inspection. You can see the muffler breakage on img_1722. There also appears to be rust on all welding joints and frame surfaces.
The frame has excessive corrosion. I had some suspension replaced last year and it was fine today my dealer told me there is excessive corrosion and recommends not to put any money into it. Also told me this happened quickly because if it was there last year he would have informed me then not to do the suspension work.
Extensive rust has destroyed both the front and rear suspension crossmembers. Mechanic shop has advised that it will no longer pass virginia state safety inspection and must be condemned. After researching this condition further, I am finding this to be a common failure found in 3rd generation 4runners utilized in climates where road salt/chemicals are used.
Purchsed the vehicle used and the underside/frame is completely rusted.
