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
Of the 17 model years of Toyota Tundra we track for body problems, this one carries the most owner complaints on file — 141.
Owners have filed 141 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.
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

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 vast majority of complaints center on frame rust that starts early and accelerates quickly. Owners consistently describe finding rust in frame rails, cross members, suspension mounts, and fuel tank attachment points within 5–10 years. Many completed Toyota's 2014–2015 corrosion-protection spray treatment (campaign D0D), but the coating failed to stop rust progression; some owners provide evidence dealers didn't even remove the truck bed or existing rust before spraying, skipping the 8–9 hours of proper labor and doing the job in under 4 hours. Frame corrosion has led to critical failures: brake lines rupturing, fuel tanks dropping, stabilizer bars pulling free, and structural integrity degrading enough that mechanics refuse to put the truck on a lift.
Owners report Toyota's campaign expired in July 2015. After that date, Toyota refuses any assistance, even when corrosion is severe or ongoing, citing the closed campaign. One owner received an airbag recall notice but no frame-rust notice, despite Toyota having his address. Another had his vehicle marked "undriveable" in the dealer system without permission once the corrosion became obvious.
A secondary issue: truck beds rust at the mounting bolts and bolt holes, developing golf-ball-sized holes in the floor; Toyota offers no remedy. One owner reported a plastic tailgate latch clip breaking repeatedly despite warranty, and one other noted intermittent rear-end vibration under braking that persisted after suspension component replacement, with the dealer offering no resolution.

Failure modes owners describe
Frame rust/corrosion and perforation
Owners report widespread frame rust starting at multiple locations—frame rails, cross members, fuel tank mounts, spare tire mounts, and suspension attachment points. Many develop holes large enough to pass a hand through; some rust through completely. Corrosion appears to accelerate after the limited service campaign rust-treatment spray is applied, or develops soon after despite prior treatment. In several cases, frame corrosion leads to functional failures: brake lines rupture (narratives #3, #5, #21), fuel tank straps fail causing tank to drop (#4), suspension components separate, and structural integrity deteriorates to the point mechanics declare the vehicle unsafe to drive.
When: Typically appears between 5-10 years of ownership (2006 model year vehicles inspected/serviced 2014–2020). Owners report corrosion visible at recall inspection in 2014–2015, then significantly worse by 2018–2023. Mileage ranges from ~75,000 to 199,000 miles; low-mileage examples also affected.
Symptoms owners cite: Visible rust, pitting, and flaking on frame, cross members, and undercarriage; Holes or perforations in frame; Frame rails and cross members separating at connection points; Corrosion-induced brake line rupture and brake failure; Fuel tank strap rust-through; fuel tank drops or becomes insecure; Suspension mounts corroded; stabilizer bar pulls out; Truck bed bolts rusted through; bed bolts/mounting areas severely corroded; Spare tire mount rusted away; Excessive rust falling from undercarriage when door closes; Steering/front-end instability due to cross-member fracture (narrative #13)
Repairs/costs cited: Limited service campaign (Toyota campaign D0D, 2014–2015) applied corrosion-resistant spray/coating or CRC (black coding) to frame. Owners report this treatment failed to stop or prevent continued corrosion. Proper factory remedy (per corporate guidelines in narrative #2) requires removal of truck bed, removal of existing rust, and reapplication of protection—8–9 billable hours. Many dealers completed the service in <4 hours without removing bed or rust. Full frame replacement required in severe cases but not performed under expired campaign. Repair costs cited range from ~$179 (single component) to full frame replacement (cost not specified in narratives, but implied to be substantial).
Recalls/TSBs owners mention: Limited Service Campaign D0D (corrosion protection coating/spray) issued 2014–2015 for 2004–2006 Tundras; campaign expired July 2015. Toyota settled with frame manufacturer Dana Corp for ~$25 million (narrative #2). After expiration, Toyota refuses further assistance, citing campaign closure even when corrosion is severe or ongoing. Owners received recall notification for airbags but many did not receive frame-rust campaign notice. Toyota corporate customer care offers no second evaluation or remedy after campaign expiration, even when corrosion persists. Some dealers refuse service, claiming 'safety campaign, not recall.' Manufacturer states vehicle 'out of warranty' and corrosion 'due to customer not undercoating' despite no undercoating recall. One dealer (narrative #2) documented refusal to perform proper scope of work per corporate guidelines.
Truck bed rust and attachment failure
Separate from frame corrosion, owners report the truck bed itself rusting rapidly and deteriorating around the bolts and mounting points where it attaches to the frame. Metal surrounding bolts corrodes entirely. Holes (described as golf-ball sized) appear in the bed floor. One owner describes the interior bed condition as resembling the Titanic wreck. The bed is at risk of collapse or separation from the frame while driving.
When: Owners report bed rust 'several years' into ownership; corrosion appears to accelerate after middle years of ownership and is visible or becomes critical by the time of recall inspection or routine maintenance (2014–2023 timeline for this 2006 model).
Symptoms owners cite: Rust and corrosion around all bolts securing bed to frame; Metal surrounding bolt holes completely corroded; Golf-ball-sized holes in truck bed floor; Bed floor extensively pitted and flaking; Risk of bed collapse or separation from frame
Repairs/costs cited: No factory remedy exists for truck bed rust under any recall or campaign. Repair requires bed replacement or extensive patching/welding. Owner (narrative #41) states the cost is personal responsibility and reports Toyota corporate response: 'If we fix it for you, we have to fix it for everyone.'
Recalls/TSBs owners mention: No recall or service campaign for truck bed rust. Toyota refuses warranty or assistance. Corporate response to owner inquiries: defect is not covered and owner must pay for repair. One owner reports lifetime warranty claim for undercoating denied.
Power outlet/panel repeatedly loosening and falling
One owner reports the power outlet panel (on the dashboard or interior) repeatedly loosening from its mounting, falls to the floorboard, and interferes with brake and accelerator pedal operation. Dealership repeatedly replaces a pin securing the panel; problem recurs within weeks to months. Multiple shops confirm the panel mounting is worn and vibration causes repeated failure.
When: Initial failure reported in February; recurrence within one month, then recurring repeatedly over subsequent service visits.
Symptoms owners cite: Power outlet panel becomes loose; Panel falls to floorboard; Panel obstructs brake and accelerator pedals, making safe operation difficult; Problem recurs shortly after dealer repair
Repairs/costs cited: Dealership replaced a pin securing the panel (twice). Independent shops diagnosed the panel as worn/damaged. No permanent fix reported.
Tailgate latch clip failure
Owner reports inability to open tailgate due to plastic clip failure. Dealership replaced the clip approximately 4 years before the complaint. Two months later, same failure recurred. Dealership repair cost: $179. Clip is warranted for 1 year only, meaning owner expects repeat failure and additional cost within 12 months.
When: Initial failure ~4 years before complaint; recurrence after 2-month interval following repair.
Symptoms owners cite: Tailgate cannot be opened; Plastic clip holding tailgate latch breaks repeatedly
Repairs/costs cited: Plastic clip replacement, $179.
Recalls/TSBs owners mention: Clip warranty: 1 year only. Toyota issued service memo regarding this problem on 2007 models but not 2006 models, though the issue appears identical.
Rear-end vibration/motion under braking
One owner reports strange motion/vibration from rear end whenever the vehicle comes to a full stop, feeling like the truck is being hit from behind. Dealership adjusted center support bearing, replaced transmission mount and cross member. Problem persisted after repair. Second visit to dealer resulted in statement that 'this is something that happens to some vehicles' and no further remedy was attempted.
When: December 2009; repairs attempted January 2010; issue unresolved as of complaint date.
Symptoms owners cite: Abnormal vibration/motion from rear end when braking to a full stop; Sensation of impact from behind
Repairs/costs cited: Center support bearing adjustment, transmission mount replacement, cross member replacement—all completed but ineffective.
Recalls/TSBs owners mention: Dealer stated this is a known issue affecting 'some Toyota vehicles' but offered no remedy after initial repairs failed.

My Toyota tundra has sever frame rust and will not pass inspection. The truck has 173,000 miles on it and I just got it paid off and will now have to junk it.
The vehicle frame is showing major signs of rust. This apparently is a very common issue. When I contacted Toyota regarding this matter I was told that they issued a temporary service for this but I was never notified. This is a huge issue since whenever conponents need replacing the bolts must be cut off due to rusting. This is a safety issue as well since certain areas are thinning on the frame.

Common questions
How serious is the body problem on the 2006 Toyota Tundra?
It's a documented issue but not catastrophic. 141 complaints have been filed. Repairs average $1,500 and most owners catch it before it causes a breakdown.
At what mileage does the body typically fail?
Across the 98 complaints that reported odometer mileage, most body failures cluster between 82,000 and 160,000 miles, with the median around 126,159. A quarter of owners report trouble before 82,000; a quarter make it past 160,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,500 for body repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to body?
No active recalls currently cover body issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
