Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage

What stands out
Owners have filed 29 body complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 12 model years of Toyota 4Runner in our records for body problems, this one ranks #3 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering body on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
full bulletin at NHTSA ↗The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It
full bulletin at NHTSA ↗Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination. Follow the Removal Procedure in this bulletin to remove the RapgardTM protective film within 90 days from initial application.
full bulletin at NHTSA ↗Vehicles may occasionally be subjected to contamination by airborne iron particles shed from railroad tracks, train wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid. Follow the Repair Procedure in this bulletin to clean vehicles that may have been subjected to contamination by airborne iron particles such as rail dust during rail transportation or extended storage near industrial ar

The failure pattern owners describe
The 2007 4Runner shows two dominant body issues. The first is widespread frame and structural corrosion. Owners report frame rust severe enough to compromise steering and suspension integrity—in one case, front-end steering rusted and disconnected completely while driving at 25 mph, forcing towing. Others describe corrosion of cross members, suspension components, control arms, and support brackets progressing at alarming rates despite proper maintenance and garage storage. A dealer told one owner the rust made the vehicle unsafe to drive. Owners note this appears to be a known Toyota frame issue affecting multiple model years.
The second issue is failure of the rear tailgate and hatch handle rubber components. The rubber deteriorates, melts, or becomes tar-like, causing sticky operation, inability to open in cold weather, and black residue transfer to hands. Some handles become so degraded that the tailgate may open unexpectedly while driving. One owner had the part replaced under warranty, only to have it fail again with an identical replacement. The replacement parts use the same material, suggesting no design fix. Some owners mention concern about overheating wiring causing the meltdown. A minor issue involves ground clearance discrepancy reported by one owner.

Failure modes owners describe
Frame and structural corrosion
Widespread rust affecting frame, cross members, suspension components, control arms, and support brackets. Corrosion progresses rapidly despite proper maintenance and garage storage. In severe cases, steering components rust and disconnect from frame, creating total loss and safety hazard.
When: Observed at 100k miles and beyond; one owner purchased vehicle with some frame rust that then deteriorated rapidly within months
Symptoms owners cite: Flaking metal from undercarriage; Loss of steering control due to front-end rust disconnection; Vehicle sway while driving; Inability to remove bolts for engine compartment service due to rust; Holes forming in exposed steel areas; Structural weakness forcing towing instead of driving
Repairs/costs cited: One vehicle required complete front-end frame replacement; deemed total loss. Multiple owners advised by mechanics and dealers vehicle is unsafe to drive. Repairs described as insurmountable or impossible due to insufficient remaining metal.
Recalls/TSBs owners mention: Toyota has issued no recall. Dealers acknowledge frame rust exists but decline to address it, sometimes attributing it to maintenance issues. One dealer noted similar Tacoma recalls should apply to 4Runner due to shared frame platform.
Rear hatch and tailgate handle rubber degradation
Rubber handle covers on rear hatch, tailgate, and back door latches deteriorate, melt, or become tar-like. Material fails in both hot and cold weather. One replacement part failed identically after warranty coverage.
When: Reported across model year; one owner had failure replaced June 26, 2009, then recurred
Symptoms owners cite: Rubber melts or becomes sticky to touch; Black tar-like residue transfers to hands; Handle difficult or impossible to depress, especially in cold weather; Handle too hot to touch in summer heat (nearly burns fingers); Tailgate may open unexpectedly during driving; Hatch release does not function properly
Repairs/costs cited: Dealers report replacement costs approximately $350 for entire latch assembly including electrical parts. Part number cited: 84840-35010. Replacement parts use identical material, offering no permanent fix. One owner had part replaced under warranty in 2009; same failure occurred later.
Recalls/TSBs owners mention: Toyota denies this is a recall item. Dealers acknowledge issue is common. Insurance denials received citing intermittent functionality. Dealership told owner replacement part is same material, implying awareness of recurring failure. No TSB or recall issued.
Ground clearance specification discrepancy
Vehicle scrapes ground despite dealer claims of 9.1 inches of ground clearance. Dealer deflected concerns citing different measurement methods.
When: Present at time of purchase and use
Symptoms owners cite: Vehicle scrapes ground during normal operation

Noticed rust on frame few years ago but the dealer said Toyota will not do a anything. If tacoma is being recalled, 4 runner should be since it is build on the same frame. *dt*jb
The frame on my 4-Runner is rusted out to the point of being borderline unsafe, as per the Toyota Dealer. I don't have a scanner otherwise I would upload the pictures. The invoice from the dealer has my contact info. Not sure if you want that info.
I have a 2007 4runner with currently around 180k miles. When I purchased the vehicle it had some rusting to the frame but nothing deeming it unsafe or dangerous. Within a matter of months the frame had, and still is, rusting and deteriorating at an alarming rate. I am not sure how Toyota has got away with this issue thus far but I'm pruong
Handle/lock on rear hatch is faulty. Mechanism on the handle/lock of the rear hatch of 2007 Toyota 4runner will no longer engage to allow hatch to be opened. Problem had been intermittent, now is more problematic. Cannot open rear hatch to access the cargo area of vehicle. Dealer service dept acknowledges this is a common issue. Lots of similar issues found online. This has not been a recall…
The hatch latch has melted and presents problems in unlatching. The dealer denies this is a problem. Especially in cooler weather, I am often not able to open the rear hatch. My research indicates that many owners of this model experience the same issues. There is some concern that the cause is faulty wiring that overheats the material. Also, the replacement part is the same as the original;…
