CarComplaints.com Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

Frame rust is so pervasive on my 2008 4runner that the Toyota dealer refuses to make necessary repairs to transmission. The dealer suggested that I "walk away from the vehicle", citing future rust-related problems with caliper replacement and other routine maintenance. Rust on differential axle led to the shearing off of the fluid drain bolt, rendering that impossible to drain/refill. Attached are notes from the dealer's maintenance engineer, citing rusted cross member bolts and other components interfering with necessary repairs. I have serious concerns about the ongoing safety and road-worthiness of this vehicle.

My frame brackets that hold my suspension and other parts like my fuel tank and driveline are rusting off and my mechanic says don't bother because it'll cost more than the truck is worth. It needs a full frame change!! if I would have been driving it when the last part broke at highway speed instead of the 20 mph on a regular road we wouldn't be chatting right now because I would have been killed along with my passenger and I had just got out of a 3 day stay at a local hospital so I was definitely going slower than normal. It was my complete drivers rear spring perch and track bar off the axle and the frame side is just as bad. I'm worried one day something is going to break off at highway speed and if I don't get hurt I'll hit someone else or worse. I've enclosed 5 out of 42 photo's of the rust its serious and I need help along with lots of other 4th gen Toyota 4runner owners that will sooner or later get injured or kill someone due to the serious failures of our vehicle frames rusting. I went looking to replace the brackets and they don't sell them separately I was told I need the frame it's the only way to get what I need. So can you help me and all the other owners going through this please! we were left out of the big frame recall Toyota did because there are more 4runners that all the other 3 combined and it's very sad this happened!! the vehicle was towed to (mild to wild) 217 derby ave / orange, ct to get the parts needed fabricated from scratch because you can't buy them separately you need to buy the whole frame!

In my own words, I have a 2008 Toyota 4runner 4X4 with only 27,000 original miles and the chassis is completely rusted thru, with huge big holes on the chassis. Toyota used some very cheap metal and didn't spray any chassis pretection from rust. The rear driver side shock mount rusted completely that the shock fell off while I was driving, now there is no mount for the shock now. I almost lost control on a curve that was a little bumpy, as I passed the curve my 4runner felt like the back kept sliding, I felt like it was almost about to flip over. There are recalls for all other Toyota SUV but not for Toyota 4runner what's the difference if they used the same metal to make the chassis. My chassis is even more rusted on the front passenger side where the air conditioner has a small drip rubber tube where the air conditioner drops any ac condensation. I don't feel safe driving my 2008 4runner but it only has less than 27,000 original miles... can you. Relive that. I even have pictures and videos to prove it. Smh and I really like my 4runner.

Heavy corrosion caused the rear torsion bar to disconnect from the rear end while I was driving in Oct. 2015. The frame and front end suspension is now very corroded. You can put your fingers through the bottom of the frame just in front of the rear wheels. This vehicle only has 69,400 miles on it.

There is corrosion in the frame and drive-train components. There is pitting, rusting throughout the frame undercarriage and the suspension and differential components. This barely 4yr old vehicle is a southern vehicle. Regardless, this corrosion is a safety issue in any vehicle let alone in a 4runner with a service inception date of 11/30/2008 with 19K miles. This is totally irresponsible of the manufacturer and they claim it is not covered by warranty. Yes, it (should be) covered by warranty and more importantly it is manufacturer's liability to correct safety/quality issue.

A steering vibration occurs at highway speeds between 65 mph to 80 mph. A new set of tires where installed and balanced properly at discount tire but the steering vibration would not go away. Then I had the store change the tires and install another set of four thinking bad tires where installed. The tires are dunlop grandtrek at 20 what Toyota originally puts on the car. However, the steering vibration is still there. I have had the tires balanced a multiple times and the problem is not fixed. I even took it to the dealer to balance them and they also checked the steering and suspensions and tires and found nothing wrong. However, there is still vibrations at highway speeds.
