Structure

285 reports3 crashes
“Toyota has had issues with their frames rusting out and the 4th generation 4Runner is not exempt from this issue. My 2003 is requiring extensive work to keep it on the road safely due to frame rust. A recall to replace frames should be in place.”
Owner complaint to NHTSAFiled Oct 10, 2024StructureODI 11619222

Suspension

114 reports1 crash
“I purchased this 2003 Toyota 4Runner in 2018 under what I assumed was prime condition, for a vehicle that spent the majority of its life in Nebraska/Kansas before I moved to Texas in 2021. At 87,400 miles at the time of purchase, the vehicle had no visible damage to the exterior besides a few paint chips, some minor hail damage and scratches, and some easily fixed surface rust in the paint on the tailgate. The previous owner had driven it leisurely and had kept the miles low after 15 years. The car has had some mechanical issues, but nothing out of the ordinary outside of some regular maintenance over the first few years. Being close to 100,000 miles, the timing belt and pump was replaced around 98,000 miles. Other issues have been fixed periodically, please reference the attached files. After joining a Toyota 4Runner 4th Generation Facebook group and seeing a post about another's issues with rust damage in October 2020, I decided to take a look at my own frame. I then inspected my own vehicle, and found significant frame rot damage. It is extensive, with significant rust to the frame, with large holes and soft patches that question the integrity of the frame…”

“I BOUGHT MY 2003 TOYOTA 4RUNNER LESS THAN A YEAR AGO FROM AN AUTO GROUP (TOYOTA, HONDA, ECT) AND HAD THEM PERFORM A SAFETY INSPECTION. SINCE IT WAS USED I KNEW THERE WOULD BE SOME ISSUES, THE ONLY PROBLEM IT HAD WAS THE RECOMMENDED SERVICE WASN'T COMPLETED AT 90K MILES (TIMING BELT, WATER PUMP, ECT). I WORKED THAT INTO THE DEAL AN WAS ON MY WAY. AFTER DEPARTING THE U.S. AND SHIPPING MY CAR TO HAWAII, THE INSPECTORS HERE FOUND A LOT OF RUST ON THE FRAME AND SAID IT COULD BE AN ISSUE GETTING AN APPROVED SAFETY INSPECTION (REQUIRED FOR REGISTERING THE CAR IN HAWAII). THEY SAID IT ISN'T SEVERE NOW, BUT CAN BE LIVING IN THIS STATE AS IT IS VERY RUSTED AND WILL CONTINUE TO DO SO IN SUCH A HUMID ENVIRONMENT. THEY ALSO SAID THAT TACOMAS FOR THAT YEAR HAD A RECALL DUE TO EXCESSIVE FRAME RUST (SIMILAR IF NOT THE SAME FRAMES) BUT 4RUNNERS DO NOT, SO THEY RECOMMENDED I TALK TO TOYOTA ABOUT IT. I CALLED THE TOYOTA SERVICE CENTER HERE AND THEY SAID THERE IS NO RECALL AND IF I WANTED THE FRAME FIXED OR REPLACED, IT'D HAVE TO BE AT MY EXPENSE. TOYOTA'S ARE FANTASTIC VEHICLES, I JUST HOPE THIS COMMENT AIDS IN THEIR DECISION TO APPROVE A RECALL ON 4RUNNER'S FRAMES DUE TO RUST…”
