My recently purchased Toyota FJ Cruiser was found to have severe rust underneath the car . Nuts and bolts have rotted away with the part now held together by rust weld. New straps are holding up a dented gas tank which my mechanic thinks fell when the original straps failed. Is it a safety issue when a gas tank falls off a traveling vehicle? I don't know what other problems may arise from this, but I have been online and there seems to be complaints of this nature all over the internet. Toyota ordered a recall on several models for this problem, but not the FJ. This many people can't be making this stuff up. At some point it is going to lead to a death, if it hasn't already . Have only had this vehicle 2 weeks, and I find it hard to believe Toyota can't address this problem like it did with other models of their fleet. One lady's pickup bed almost separated from the front of the truck. …
Our 2007 FJ Cruiser when brought in for annual inspection has been deemed unsafe for use due to crack in frame due to corrosion. The vehicle has no other mechanical issues and runs as if new. We invested in 5 new tires and now find ourselves possibly having to purchase a new vehicle. We witnessed all the other Toyota vehicles frames being replaced due to the recall regarding insufficient undercoating and excessive rust. We inquired if our vehicle was included and if there was reason for concern and were told No. We also own a 2010 Prius which we purchased new. We had no reason to question the validity of the answer. Years later we are grateful we did not experience any incident and crack was discovered before one happened. We now want to know why we did not get a replacement as did all the other models.
I purchased the vehicle with a clean carfax on 12/2/2021 Flew from Phoenix to Dallas to pick it up. Drove the vehicle from Dallas to Phoenix. The Brakes malfunctioned on the drive home. Fortunately it was late at night and not many vehicles on the road. Took car to mechanic on 12/4/2021. The frame, brakes, suspension, exhaust and engine mounts had been sprayed over to cover severe rust and rot of the the frame and undercarriage. The vehicle cost 14k The repairs to be done 20k The vehicle is not roadworthy and has not been driven since ai got back to Phoenix. The dealership purposely didn't disclose the frame or brake damage. The dealership sold this vehicle knowing it was for my daughter and 3 year old granddaughter
I was driving down the street after filling up my fuel tank. I drove approximately 1/2 mile when I heard a sound, felt a clunk and stopped immediately. My fuel tank was hanging down on the ground. I called AAA and requested a flatbed and to bring a strap. He did not bring a strap and when my truck arrived at the mechanic the fuel tank had completely separated from the vehicle. The other complaint I have is the rusted frame. I purchased this vehicle used. I did not notice that the tube before the rear axle which holds suspension supports to the frame were completely broken off and separated from the rusted out frame that has failed. It has been welding but the rusted frame is very difficult to weld to.
The fj cruiser is a common issue for rot/ rust on the frame of the vehicle, I have clean the frame often during the winter months and my frame is continuously rusting and rotting the frame of the vehicle I have decided to not drive the vehicle till the frame is either replaced or repaired due to the safety concern of driving it on the road, numerous others have same incidents of the holes in the frame due to rust the manufacturer did not put any kind of corrosion treatment on the frame to stop this from happening the frame flexes when accelerating and is not safe for anyone to including my passengers or other people on the road
the frame and associated components are severly corroded putting the vehicle in danger of the back axel detaching . i was informed of this by a repair shop who were concerned of the safety of operating vehicle. there is some type of coverage for related vehicles but not for this model. i think this is the same platform which was recalled under a truck model. toyota refuses any coverage or help for this problem. the vehicle has 70k miles but is unsafe to operate. photos are available. although the top of the vehicle is what you would expect with 70k miles, it is unsafe to operate because the back axel could fall off at any time
Backing out of my driveway we heard a slight pop and a dragging feel on the right passengers front.( thought I ran over a landscape brick) Stopped and inspected nothing was under the vehicle starting to leave my complex vehicle started to shake some. When I got up to 20 MPH it was obvious I should not drive. Called tow truck. Thought I needed ball joints or something similar. Mechanic said frame was completely rusted out and unfixable. The Toyota FJ cruiser is suppose to be a tough off road SUV which I never used for off road driving They even advertised how tough the frame is in commercials . I see there has been recalls for other Toyota models of SUV and trucks of the same year and their is a class action lawsuit already started I think in California. If I would have continued to the freeway A serious accident would had happened. …
