Within that volume, owners reported 34 crashes, 3 fires, 37 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 5 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 1 investigation file overlapping the 2006 4RUNNER. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.

20250911STRUCTURE:BODY

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.

Dangerous and rusted through frame. The vehicles frame should have been recalled like the other Toyotas affected.

20250209UNKNOWN OR OTHER

We took the vehicle in for inspection and it failed due to the exhaust leaks, and more importantly the frame rusting out. We never received the recall notice for this issue. We have owned this vehicle for many years, so there is no reason we would not have been notified for the recall of the frame. The vehicle was just serviced last year and we spent a great deal of money to keep it running properly so we would not have any issues and it would last us for quite a long time to come. With the frame being rusted through, there is simply no way to keep this vehicle safe. Toyota did not notify customers that had the vehicles with the frame issue. This is something that is simply not acceptable. We are a family of Toyota owners and have always depended on the reliability of them. Finding this out has really shocked us and honestly diminished our trust in the Toyota reliability. Is Toyota willing to fix this issue, are we just stuck with this. Please help.

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.

20231106TRAILER HITCHES

While towing a 16' utility trailer using the 2" ball on a Switch Ball #42178, the ball separated from the shank. I was driving my 2007 Toyota 4Runner traveling on the highway at about 60mph at the time. Fortunately the safety chains did their job and prevented the trailer from completely disconnecting from the vehicle. Upon stopping my vehicle several hundred feet after separation, I found the 2" ball still locked and secured inside of the trailer's coupler, and the shank still securely attached to my vehicle. As a result my rear bumper is now heavily damaged from the trailer contacting it after uncoupling from the vehicle. I'm glad nobody was hurt or killed as a result of this incident. If the safety chains had not done their job, the unattached trailer could have caused serious damage, injury, and/or death. This incident could have also resulted in losing control of my vehicle, which thankfully I did not. This Switch Ball #42178 was purchased in September of 2022 and this was the fi

20230312SERVICE BRAKES

Corrosion of pistons in front brake calipers results in an increase in braking stopping distance. Everytime the front brake pads are replaced the same issue is encountered, defect has taken place three times. In the four piston brake caliper the inside pistons on both the left and right caliper are frozen in place . The brake pads on the outside position have twice as much wear as the inside pads. This is an indication of uneven braking leading to increased stopping distance . Toyota maintains , there is not a problem, yet in forums on the web there are many experiences with owners having the same problem , resulting in costly repair bills. There is no warning of reduced braking efficiency .

20230306EXTERIOR LIGHTING

The vehicle headlights have failed on multiple occasions. The cause of the failures was ingress of water into the sealed headlamp assembly. The problem was reported to Toyota. Toyota took no action regarding the reports. The entire headlight assembly was replaced three (3) times at our expense. The problem persists. Attached is a photograph of the second (replaced) clearly showing water inside the headlight assembly. The current (most recent replacement) has also experienced water ingress and is available for inspection. The subject vehicle was inspected by three different body shops (two if which are authorized Toyota shops). It was confirmed by all three shops that there is no vehicle design feature that could cause water ingress in the headlamp assembly. This is a serious safety issue and has been brought to Toyota's attention with no response.

20230305UNKNOWN OR OTHER

The frame is corroded and rusted to the point that it’s not safe to drive. This was discovered by our service technician when we had the vehicle inspected for a rattling noise in the rear. 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.
