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.

Our 4runner's frame is rusting away and Toyota refuses to fix their mistake. The frame is similar to the Tacoma that was recalled and repaired, so I contacted them and was informed that they weren't going to fix our 4runner that has the same issues. I was less than pleased with their response. This could've quite easily caused a severe accident. Luckily my mechanic caught it in time before that happened

Went to inspect my 4 runner, was told I have major rot and rust on the frame they are unable to inspect, vehical is unsafe to have on the road. My SUV is mint with low miles how can this be. I always take care of my vehicals.
I took my 4runner to the dealership that is was purchased and was informed that it needs a new frame due to excessive rust/rot. I am being told that it is beyond repair and is a safety issue at this point.
We were hearing a noise in the rear suspension (LH) when braking or accelerating. The car was not stable to drive. We lift the vehicle and found that the frame is rusted due to the manufactuer did not protect it at the factory. The rear left suspension bracket was almost dissapeared. The vehicle was dangerous to be driven. We had to reinforce the affected part to keep the vehicle in service, but the frame is rotten. The engine, body and interior are in perfect condition but the frame.
My frame is seriously rusted and needs replacement making my vehicle unsafe. There is rust in numerous locations. I just visited a repair shop and they told me that I would need to reinforce or replace the frame. The cost for reinforcing the frame is over 5000 dollars. The vehicle is in great shape other than the frame and I was hoping to drive it for at least a few more years. Your department has found similar issues with other Toyota that have exactly the same issue and are built upon similar frames made exactly the same way. These models include the Tacoma, sequoia, and Tundra. It is my opinion that Toyota failed to treat their frames properly and the dealer failed to take the necessary steps to inform me of the issue when the vehicle was brought in for regular maintenance.
The contact owns a 2003 Toyota 4runner.

Rear axle badly rotted. Car has 66,000 miles on it. Requires replacement which is apparently an extremely expensive and sensitive process. The corrosion seems to be extraordinarily premature and due to substandard frame materials and treatment of same. Acton Toyota had already welded in a frame bar 2-3 years ago. Called (800)331-4331 (Toyota motor manufacturing)spoke with a customer service rep (angie) and her supervisor (maria) who stated that the warranty on the frame expired in 2006, they were clear about Toyota's position that they will do nothing w/O a factory recall. This is, apparently, not an isolated issue.

The contact owns a 2003 Toyota 4runner. The contact stated that the front passenger side frame, front driver side lower support, and radiator bar contained rust. The vehicle was taken to Toyota of naperville (located at 1488 ogden ave, naperville, il 60540, (630) 528-1459), but was not diagnosed or repaired. The manufacturer was notified. The failure mileage was 184,000.
Excessive and premature corrosion has developed at various locations on the vehicle frame such that I am concerned about the structural integrity of the vehicle frame and it's impact on the operational safety when I'm driving this vehicle. It appears that the corrosion has originated on both the external frame surface welded seams and also from internal frame surfaces. I took proactive measures to have my frame treated for corrosion resistance by an after market vendor in an attempt to abate early signs of corrosion but the corrosion from internal surfaces has now worked it's way thru showing clear holes/gaps/separation in the frame structural components. Rusting from the inside out adds to my concern about the vehicle operational safety. My vehicle has had all regular, scheduled maintenance performed by a Toyota dealer whom has also pointed out the structural issues resulting from corrosion. I learned about and was shown the corrosion problems directly from the dealer service department while my vehicle was elevated on a lift in a service bay. Attached are pictures taken recently (5/17/19) while at the dealer of the more obvious problems at various locations on the frame.
