“MYself and my fiancee were driving to our family's home, the rear defrost was on due to foggy windows as we were driving down the road there was a loud noise from the back half of the 4 runner. I had turned and looked back behind me and the rear hatch window was completely shattered. Its still intact in the window frame but about to fall out. This happened out of nowhere no warnings or anything.”Owner report · Visibility/Wiper · Dec 2025
“The frame under the car rusted so much that the gas tank literally fell through the frame to the ground. This put my son at risk and fortunately he was able to pull over in a residential area and exit the vehicle. A mechanic and welding company both assessed the vehicle and acknowledged the u unusual and excessive rusting. In researching online and speaking to car experts, this seems and is confirmed to be poor manufacturing and materials used for the frame.”Owner report · Structure · Sep 2025

“The rear window on my 2006 4Runner suddenly shattered. I had just cleared the car of snow, put my son in the car and left the house. Less than 1/10th of a mile down the road it exploded. Glass could have gone all over the child in the backseat. There have been past issues. Toyota offered an extended warranty on the part until 2018, so they are aware of the problem. Not yet. No warnings.”Owner report · Visibility/Wiper · Jan 2024

I reached out to Toyota and was told that no problems are available regarding this issue. I have maintained my 4Runner meticulously and timely since I purchased brand new. There is no rust on the body, just the frame.”Owner report · Unknown Or Other · Feb 2023
“My 2006 4Runner Toyota frame is rusted and falling into pieces. From the rear especially and underneath. I'm scared if someone rear ends me that the impact could be life threatening due to the frame falling to pieces as I drive and the vehicle sits.”Owner report · Unknown Or Other · Jan 2023
“My 17 year old son was parked and when he turned off the defrost the rear hatchback glass shattered. This scared him a lot as we do not know what happened and thankfully he was parked not driving. This is a safety and potentially dangerous issue. We purchased this used vehicle and had Toyota thoroughly inspect and update and upgrade anything he needed and they never told us this was an issue. We researched it online and it has been an issue. This should have been addressed and recalled. I brought in vehicle so that they can fix it and they are saying they won't even though it's their equipment defect.”Owner report · Unknown Or Other · Nov 2022
