What owners report most

Verbatim excerpts from NHTSA complaints, by component

Structure

143 reports2 crashes
“Frame is rotting away. The tacomas, tundras, sequoia were recalled for this issue. The tacomas frame is very close in design to the 4runner. The main difference is the 4runner uses coil springs whereas the tacoma used leaf springs. Toyota stated that because the 4runner was made in Japan unlike the others that were made in the USA, that the 4runners were not part of the recall.most of the 4runners that are no longer drivable, are because of rotted frames. The repair kits that fix the rotted frames on the tacomas are the same kits that fix the 4runners. Now toyota won't even touch my vehicle for other repairs because of the rot holes.”

“MY TOYOTA 4 RUNNER ENTIRE FRAME AND CONNECTING COMPONENTS IS COMPLETELY RUSTED OUT AND CRUMBLING. THE CAR ISN’T SAFE TO DRIVE AT ALL. TOYOTA IS AWARE OF THIS AS ITS COMMON AND NO RECALL IS IN PLACE. WHEN DRIVING, ONE TIRE IS COMPLETELY BARELY HANGING ON AS THE FRAME IS FAILING ALL OVER. THE CAR WOBBLES AND SWERVES AND FEELS AS IF IT WILL COME APART AT ANY TIME. THIS FRAME WAS NEVER TREATED PROPERLY WHEN INSTALLED. IF YOU WENT OVER 50 THE CAR COULD FALL APART AND WOULD BE EXTREMELY DANGEROUS.”
