2007 Toyota 4runner — Known Issues & Recalls

Your 2007 Toyota 4Runner is swaying side-to-side while driving at normal highway speeds (around 35 MPH), even though no warning lights are showing up on your dashboard. You've also noticed that the subframe underneath your vehicle has developed significant rust and corrosion. This combination of swaying and structural corrosion could indicate suspension or frame damage that needs professional inspection. A mechanic will likely need to inspect the suspension components and assess the extent of the subframe corrosion to determine what repairs are needed.

Your mechanic discovered severe rust underneath your car during a brake repair, with metal flakes actively falling off the frame. The mechanic warned against using a lift again due to concerns about structural integrity, noting this level of rust is abnormal for a well-maintained vehicle. This could affect the safety and structural stability of your car and may require professional rust assessment and repair.

Your 4Runner's frame has developed extensive rust that a Toyota dealer has indicated may be unsafe. The structural damage is significant enough to warrant attention and potential repair or replacement of affected frame sections.

Your 4Runner's frame and suspension components, including the control arms and support brackets, are showing excessive rust. A Toyota dealership indicated that proper maintenance may help prevent or slow rust development. Over time, rust can weaken structural integrity and suspension reliability.

Your 2007 4Runner's frame is rusting and deteriorating rapidly, even though it only had minor surface rust when you bought it. The rust has gotten noticeably worse within just a few months and continues to spread at an accelerated rate. Frame rust repair typically involves sanding affected areas, applying rust treatment, and repainting or applying protective coatings to prevent further deterioration.

Your 4Runner's frame has corroded severely and faster than the rest of the truck's metal, making it unsafe to drive. A Toyota dealer inspected it and confirmed the frame is unsafe, with dangerous rust around the steering control arm and rear axle control arm mounts that could cause the frame to fail and lose vehicle control. If the rusted frame breaks, you could be thrown into traffic, endangering yourself, passengers, and other drivers. Fixing this typically requires frame repair or replacement, which is a major structural repair.

Your 4Runner's frame has rusted through on the passenger side following an accident, which raises safety concerns. Additionally, other parts of the vehicle show rust damage, including the gas tank area. You may want to have a professional inspect the structural integrity before driving.

Your front passenger side and back driver side doors won't unlock using the remote key fob. This could be a safety concern if you need to quickly exit the vehicle after an accident or need immediate access to the car. No warning lights appeared, and you're unsure when the problem started. The issue likely involves the door lock actuators or electrical connections that need inspection and repair.

Your 4Runner's Secondary Air Injection System (SAIS) is defective, triggering multiple emissions-related diagnostic codes (P1442, P1445, P2441, P1441). This system needs to be replaced with a new one to restore proper emissions control and pass inspections. The repair involves installing a complete new Secondary Air Injection System.

While driving at 25 mph, your brake pedal sank all the way to the floor with no resistance. You had to use the parking brake to bring the vehicle to a stop during a right turn. An inspection revealed brake fluid leaking from the bleeder valve and caliper.

After your battery died and was replaced, your 4Runner lost all braking power and made a continuous loud beeping sound from the dashboard. The ABS fuse blew immediately after replacement, and a mechanic confirmed the brake module had failed. This is a critical safety issue since your brakes were completely non-functional while driving.

You discovered a mileage discrepancy on your 2007 Toyota 4Runner after purchase. The odometer showed 87,750 miles when you bought it, but when registering the vehicle, it was found to actually have 200,000 miles. This suggests the odometer may have been tampered with or rolled back before the sale. You may need to consult with a mechanic or attorney about the vehicle's actual service history and potential warranty implications.

Your brake lights are turning on and off randomly or not working when you press the brake pedal, your horn occasionally won't work, and other electrical components are failing intermittently while driving, parked, or idling. A dealer diagnosed a failed ICMU (integrated circuit management unit) that needs replacement. The fix will involve replacing the ICMU module to restore proper electrical function.

When you turned on the rear defroster in winter conditions, your rear window suddenly shattered and exploded, scattering glass throughout your vehicle and onto the road behind you. This created a dangerous driving situation and exposed passengers to flying glass shards. Toyota has acknowledged this issue in technical bulletins and offers window replacements, but there's no warning before the glass fails.

Your 4Runner's rear frame and suspension components have rusted severely due to poor water drainage design. The bottom of the rear frame has rusted through completely, and the rear control arm mounts have rusted away, which compromises suspension integrity and safety. This issue developed because water was unable to drain properly from these areas. Fixing this will likely require replacing the rusted frame sections and control arm mounts, which is a major structural repair.

Your 4Runner's frame is severely corroded, particularly at the rear where the bumper, control arms, and radiator attach to the chassis. The corrosion is so extensive that the metal has become thin enough to push your finger through. This structural deterioration affects the integrity of key suspension and frame components that support your vehicle's safety and handling.

Your front skid plate, frame, and suspension parts have developed significant rust and corrosion, including a hole in the frame. When you contacted Toyota, they indicated they have no reports of this issue and no solutions available, though they've previously addressed similar problems on other Toyota models like the Tacoma. You may need to have a mechanic inspect the rusted components to determine if structural repairs are necessary.

Your rear windshield unexpectedly shattered while your car was parked at a stop light, with no impact or collision involved. This suggests a possible defect in the glass or its installation. Replacing the rear windshield will be necessary to restore visibility and safety.

Your 2007 4Runner's frame and undercarriage are experiencing significant rust, even though the truck has been well-maintained and garaged most of its life. You've noticed the rust is more severe than what you'd typically expect for a vehicle with 128,000 miles. You believe this may be a widespread defect since you've found similar complaints from other owners and Toyota has declined to assist under warranty. Addressing frame rust typically requires professional rust treatment, protective coatings, or in severe cases, structural repair or replacement of affected frame components.

When you turned on your rear window defroster, the rear window suddenly popped and shattered, sending glass into the interior of your car. This is a serious safety hazard since broken glass can injure occupants and impair visibility. The repair will likely involve replacing the entire rear window with a new one.
