1996 Toyota 4RUNNER Problems

What owners report

Owners of this model year most often write about rust in the frame and the rear suspension attachments, usually noticed while driving or during an inspection, and often at well over 150,000 miles. The complaints describe considerable rust damage even on vehicles that were otherwise well maintained, and repeating descriptions of swaying or poor handling after a control arm or bracket separates from the frame. Separate, less common reports cover a sticking accelerator pedal, coolant and brake problems, and tire failures.

   Body and structure

   Frame rust-through and rear suspension separation

   Mentioned in 35 of 60 sampled complaints

   Complaints describe the frame rusting from the inside out, with holes and cracks appearing near the rear trailing arms, the rear body mounts and the area around the gas tank. In several accounts a control arm or bracket has separated from the frame while driving, and the vehicle then sways or pulls to one side. Owners say shops often told them the frame was too rusted to repair or weld, and that some vehicles could not pass state inspection. Mostly reported between roughly 100,000 and 260,000 miles, often on vehicles that were otherwise well maintained and sometimes in states that use road salt.

   What to check: Put the truck on a lift and inspect the frame rails, the rear trailing arm brackets and the area near the gas tank, ideally with a mechanic who knows these trucks; surface coating can hide rust. Ask whether the frame has ever been repaired or welded.

   2 excerpts from owner complaints in NHTSA records

   “I own a 1996 Toyota 4RUNNER that has frame is rusted with large holes. It has not caused an accident yet but I believe the manufacturer should be held accountable. Especially when the same company has replaced frames and bought back other models for the exact same issue. How am I (as a 4RUNNER owner) just overlooked and brushed aside.”

   NHTSA complaint #10938869, filed 2016-12, 180,000 miles

   “Frame broke due to rust by the lower control arm going straight down the road doing about 30mph almost causing me to go off the road. Had it towed to a local garage to find out it was rusted through in several places and the mechanic told me it was a common problem with this year of 4RUNNER. …”

   Suspension

   Swaying or loss of control from worn rear suspension

   • 23 complaints (14%)
   • median 186,000 mi at 19.2 yrs old (19 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2002–2021

   Owners describe the vehicle swaying, wandering or feeling unstable at highway speed, sometimes after hitting a bump or a pothole, and occasionally losing control briefly. Complaints attribute this to rusted or broken rear control arm mounts, sway bar links and shock mounts attached to the frame. Some owners also mention lower ball joint wear; others note that their vehicle was not covered by the later ball joint recall. Reported across a wide range, often from about 130,000 to over 300,000 miles, and frequently alongside frame rust.

   Recall 02V021000

   What to check: Check the rear control arm brackets' and sway bar mounts on the frame, not just the bushings and shocks, and ask about the 02V021000 stability recall. Have a mechanic check the lower ball joints as well.

   “My vehicle has been slipping a lot causing me to lose control of the vehicle it's not the first time it has happened just recently it happened again and I was told to check if there was a recall on the vehicle but there wasn't but after researching my 4RUNNER I've read there was some recalls on the car about the rear suspension.”

   NHTSA complaint #11219278, filed 2019-06, 171,253 miles

   “On december 31, 2014 we were driving in hillsboro, oh and noticed a popping and cracking noise upon stopping and accelerating. On the way home, we noticed that the noise subsided. On january 1, 2015, went to drive the vehicle just outside our corporation limit and noticed that the vehicle was swaying back and forth like a boat out on the water, and thought it was just caused by excessive wind. …”

Buying note. On this model year, frame and rear suspension rust are the points that decide whether a truck is usable, so inspect underneath before anything else and walk away from badly rusted frames. Otherwise, check the accelerator pedal action and the age of the tires, and ask for service records.
