CarComplaints.com Notes: Although the 2003 model year is the "worst" model year for the 4Runner, it's not really bad at all -- mainly it's just that the other 4Runner model years are even better. Howver the 2003 model year has no major problems & no unexpected problems for a 17-year old vehicle. We award the 2003 4Runner our Seal of Awesome, since overall versus other comparable models of the same age, it's very reliable.

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.

The rear axle assy mount bracket rusted straight through and it does a loud clunky noise while driving. Brought it to a body shop and they said I have to change the whole assy, it cant be fixed. The car was purchased from down South, theres literally no body rust, but the frame is almost all chewed away. I also cant pass NY inspection until I get it fixed, which will cost more than I paid for the car.

Vehicle was maintained at a Toyota dealership for over a decade before being informed that vehicle is unsafe to drive due to holes forming throughout the entire frame assembly from corrosion. Further research showes the frame of this vehicle resembles that of the Toyota Tacoma and Tundra models which where recalled due to early and unsafe corrosion leading to components to detach from frame while vehicle is in motion which can lead to serious life hazard. Frame and vehicle were also manufactured in Ohio dana company which is the supplier of the recalled frames used in the Toyota Tundra and Tacoma's.

The back of the truck frame has rusted through. Stationary. Front axle pics included as well. Rust, wear and tear. Not sure when it happened bc the dealership sold the vehicle to me like this. Rusted metal proves it happened awhile ago. Plus someone tried to weld it to cover up the problem. I've also put in a radiator and new muffler was completely rusted through.

I purchased this vehicle a week ago. It appears the dealer themselves never inspected the vehicle prior to my purchase. If they had, they would have know it was an unsafe vehicle to drive due to the amount of rust to the suspension, frame, and everything underneath. Just today, a Toyota mechanic had told me that it is unserviceable. If I had owned this vehicle for years, that finding wouldn't be as painful to hear. But having owned the vehicle for a week, this has made me very angry. It only has 88K miles on it. I am now afraid to drive the vehicle.

I was driving the vehicle and normal highway speed on the interstate. When I let off the accelerator, the vehicle lurched to one side, causing the vehicle to cross into the other lane. When I applied the accelerator again, the vehicle lurched in the other direction, requiring me to apply corrective action to maintain control. Upon inspection, the passenger side rear suspension link support had mostly separated from the frame due to rust. I can bend it back and forth with my hand. I have not driven the vehicle since due to safety concerns. It is difficult to control the vehicle, especially a highway speed.

Extreme rust/rot throughout my 2003 4runner frame. The body, interior, powertrain are 8.5 out of 10 the frame is a 0 I live in new england and recently purchased the 03 4runner SR5 based off it looks. I drove the 4runner of about a month before the incident happened. I was driving on a typical new england road, fairly smooth with pot holes here and there going approximately 45 M.P.H.. without any warning the 4runner sent the front of the truck hard left and the rear of the truck to the right. The tires were screeching and I was sent sideways into oncoming traffic narrowing missing cars and pedestrians in the area. I got the truck to "crab walk" back across the road into a parking out and called a tow truck. When we got the truck home the tow truck driver and I took a look under the truck to see what went wrong. The right rear control arm mount had completely separated from the frame. With the truck on ththe ground I was able to roll the rear right wheel forward and backwards about 5 inches without the vehicle moving at all. I then got under the truck and saw that the cross member under the transmission had rusted away and and what not in contact with the driver side of the truck. Also I could push holes in the the frame with my fingers around the driver/ front passenger doors. I have not driven the 4runner since and I dont have 8K+ to pay a shop to replace a frame. Toyota needs to step up and take care of its customers before someone gets killed

I purchased my 2003 4runner brand new. The vehicle has 70,000 original miles. Never in an accident. The truck is garaged. Always maintained by Toyota. Not a scratch on the truck. Interior looks brand new. However the frame has excessive rust. Found a few spots that will eventually needs to be addressed. Toyota needs to step up and fix the rust problems

Currently the frame rust is very severe and is getting to the point that I am becoming hesisitant to have it out on the road. There are areas around suspension components and axles that are very rusted which could potentially lead to casualties if the mounts were to fail.
