2003 Toyota 4runner — Known Issues & Recalls

Your 4Runner's frame has developed severe rust with two large holes on the inside of the frame just behind the front wheels and two more large holes at the ends of the rear crossmember. This structural damage compromises the vehicle's integrity and safety. Frame repair or replacement would typically involve professional welding, rust treatment, and potential structural reinforcement.

Your 2003 Toyota 4Runner's subframe—the metal framework that supports the suspension and chassis—has developed severe corrosion on both the passenger-side front and rear sections, along with the cross member that connects them. A mechanic advised you to stop driving the vehicle due to the extent of the damage. This structural corrosion could compromise the vehicle's integrity and safety, and your dealer confirmed there's no recall available for your vehicle.

Your 4Runner's frame has rusted through in multiple areas, making the vehicle difficult to steer and causing loud crashing noises while driving. The rust has progressed significantly over several years and is now severe enough to compromise the structural integrity of the vehicle. You may experience handling problems and safety concerns when driving on public roads. Addressing this will likely require professional frame inspection and repair or replacement of corroded frame sections.

Your 4Runner's frame is experiencing significant rust that requires extensive repairs to keep the vehicle safe and roadworthy. This is a known issue affecting 4Runners of this generation. The frame may eventually become structurally compromised if rust isn't addressed.

Your 4Runner's frame and chassis have developed severe rust and corrosion, including holes in the chassis itself. The corrosion has also affected the brake lines, power steering lines, transmission lines, and metal brackets throughout the frame and engine area. This is a widespread problem affecting many 4Runners of this generation, and Toyota has indicated they may address it in the future. Addressing this issue will likely require professional rust repair, replacement of corroded lines, and possibly frame reinforcement or replacement.

Your 4Runner's frame is experiencing severe rust, similar to a recall issue that affected Toyota Tacomas. While there was a recall for Tacomas, 4Runners have the same problem but haven't been included. Addressing this will likely require professional frame inspection and rust treatment or replacement of affected frame sections.

Your 4Runner's subframe has developed significant corrosion and mechanics have recommended replacement. This is the structural component that supports your vehicle's suspension and drivetrain. Toyota confirmed this isn't covered under any recall. Fixing this will require removing and replacing the corroded subframe, which is a major structural repair.

Your 4Runner's frame has developed extensive rust that has eaten through the metal, creating holes in structural support members. This weakens the frame and makes it vulnerable to damage. Addressing this will likely require professional frame repair or replacement of the affected sections.

Your vehicle's frame has developed rust that has eaten completely through the metal in some areas, creating holes that compromise the structural integrity of the vehicle. This weakening of the frame could affect how your car performs in a collision and may require professional welding or frame replacement to restore safety.

Your vehicle's chassis and frame have become heavily corroded, according to both your mechanic and a Toyota service center. Both shops determined that the corrosion makes your vehicle unsafe to drive. Addressing this issue will likely require professional frame repair or replacement, which is a major structural repair.

Your 4Runner's frame has extensive rust and corrosion damage that runs along its entire length from front to back. This is a structural integrity issue that could affect the vehicle's safety and longevity. Addressing this would likely require professional frame repair or replacement, which is a major undertaking.

Your 4Runner's frame has developed rust. Frame corrosion can weaken the structural integrity of your vehicle over time and may eventually affect safety. You should have the frame inspected by a mechanic and may need rust treatment or frame repair depending on the severity.

Your 4Runner's frame has developed extensive rust damage with large holes and soft patches that compromise its structural integrity, even though the vehicle was well-maintained and had low mileage when you purchased it. You're concerned that hitting bumps or potholes could cause the frame to crack and result in loss of control. The frame rot issue appears to be a widespread problem affecting 2003-2009 4Runners, similar to recall issues that affected Tacomas from the same generation. Addressing this would likely require professional frame repair or replacement, which is costly.

Your 4Runner has severe rust on the frame and suspension components that's causing the rear to sag by about 3/4 inch and creating holes in the frame metal. The intermediate steering column has rusted so badly that you're unable to steer the truck properly. Similar rust issues led to a recall on the Tacoma, and this same corrosion poses the same safety dangers to your vehicle.

Your stabilizer bar (the component that keeps your vehicle stable during turns) has rusted off on the back passenger side, causing your 4Runner to sway uncontrollably while driving. This is a serious safety issue that could cause you to lose control of the vehicle, especially at higher speeds. The underlying frame is rusting out, which suggests a broader corrosion problem. Fixing this will require replacing the rusted stabilizer bar and inspecting the frame for further rust damage.

You purchased this 4Runner thinking it had 150,000 miles, but discovered it actually has 306,000 miles — the odometer had been rolled back by the seller. This appears to be part of a fraud scheme where vehicles were sprayed with oil before test drives to make them smoke, pressuring buyers into negotiating lower prices before the odometers were illegally reset. Addressing this will likely require reporting the fraud to authorities and potentially seeking legal remedies against the seller.

Your driver's side door won't open even though the electronic locks work—the mechanical door latch inside is stuck and won't release. This is a safety concern because you could be trapped in an emergency situation like a fire or flood. The repair requires removing the door panel to access and fix the internal latch actuator, which can cost around $1,150.

Your Vehicle Stability Control (VSC) system can unexpectedly turn off due to a software glitch when the car's emissions system detects a problem — even though the two systems are unrelated. Toyota has identified this firmware issue, but it affects an important safety feature that helps prevent skids and loss of control. The fix will likely involve reprogramming the vehicle's computer system to correct the faulty software logic.

Your 4Runner's frame has experienced severe corrosion throughout, which has caused structural damage to the frame itself. This is a serious structural issue that will require professional inspection and repair.

Your 2003 4Runner is experiencing multiple issues affecting the wheels, brakes, and engine. You're seeking information about whether there's a recall that might address these problems.
