Steering

13 reports
“While vehicle was parked and not in use, upon entering the vehicle, the steering wheel/column dropped out of its locked position on its own. Disassembly of the steering column revealed that the tilt-lock mechanism's steering lock fracture bolt has broken in half on the right side. This cause the steering wheel to fall out of a locked position and allowed the entire column to rotate skewed to the left side. The steering wheel became dangerous to use as it was in a freed position that allowed the entire column to move while providing inputs into the steering wheel. Had this occurred while the vehicle was in motion, it could have caused a sudden loss of steering control and significantly increased the risk of a crash or injury. The problem was confirmed by an independent mechanic upon teardown of the steering column, who visually verified the broken fracture bolt and the resulting free movement of the column. There were no dashboard warning signs, error messages, or noticeable symptoms prior to this event. The column simply came loose and dropped when entering the vehicle after it had been parked. The vehicle had about 120,000 miles at the time of failure.”

Suspension

10 reports
“TRD PRO MODEL Clunk at low speeds. FOX shocks on TRD PRO make clunking sound at low speeds. Toyota replaced 3 shocks under warranty. The 3rd one they charged me labor but covered the shock. Car has highway miles and very little time spent off road as I live in NY. As of today clunking is back in full force. Seems to be an ongoing problem if you google clunking fox shocks Toyota TRD 4Runner.”

Service brakes

“Today while I was driving home from work, in a snow storm, suddenly a low braking power notification and ABS malfunction popped up on my console with loud beeping and my brakes completely stopped working. In order to avoid hitting the car in front of me I had to swerve to the shoulder and come to a stop.”

Wheels

4 reports
“Bought the vehicle brand new and have been dealing with a steering wheel/vehicle shake ever since. The vehicle feels out of control around 55-65mph(like death wobble) and the ride is rough at any speed over 50mph. This has been a serious issue on the highway with instances of crossing lanes because of lack of control over steering. No warning lights have ever come on. Been to the dealership many times complaining about the issue just to be told that the "problem can't be replicated". I have taken it to several tire shops as well to have the wheels/tires balanced but nothing seems to help. I even bought new wheels and tires just to see if this was the cause and still no solution. This is a serious problem that thousands of 4Runner owners are experiencing and Toyota needs to get to the bottom of this. This absolutely should not be happening on brand new/modern day vehicles. I believe this is a multivariate issue causing the shake - a mix between wheel/tire balance, steering column, and possibly the drive shaft/differential/CV components. The problem must be big if Toyota continues to deny the problem year after year after year.”

Electrical system

3 reports1 fire
“Several door lock actuators have prematurely failed. The first to do so was front passenger door in summer 2024; front driver door lock failed a few months after. Most recently, approximately 4 months ago, the lock actuator for liftgate failed. This poses safety hazard in easily exiting vehicle and/or entering it if in dangerous situation. I have been communicating with local Toyota dealership for months about repairing these defective items, They have acknowledged awareness of an issue with the actuators, but have offered no help. I have read there is a class action lawsuit pending about this issue. [XXX]”
