SUSPENSION — Filed 06/12/2025

Front Coil Spring Cracking (TRD Pro Models) I observed cracking of the front coil spring, a design defect in the spring's termination and how it sits on the top hat and bottom perch. This can lead to a sudden loss of control and a crash. Furthermore, pieces of the broken spring coil can fly out underneath the vehicle and cause serious injury to person and/or damage property, when vehicle is driven at highway speeds.

ENGINE — Filed 01/24/2025

My transmission went off with no warnings and my vehicle has been serviced at the Toyota dealer since I bought it and they never mentioned to me there was an issue with my transmission which is very odd. So I was wondering is this is normal or if there others owners with the same problem. Now I don’t have a vehicle because the transmission is in back order and I can’t even get a rental car because it wasn’t an accident or a recall. So I would like for you to look into this issue for this Toyota model.

AIR BAGS — Filed 04/05/2024

I was just in my second front end collision and for the second time, my front airbags did not deploy. The first instance, I hit a deer head on going 75 mph on the interstate. Last week, I T-bone F150 at 35mph - hard enough to make that truck spin around - and had injuries to my head, knee, and hand, and yet the airbag did not deploy once again. In both cases, my car sustained over $10,000 and damage to the front end.

STEERING — Filed 02/10/2024

All of a sudden it was so difficult to steer I ended up off my driveway and almost took out my chain link fence. Two hands on left side of the steering wheel and yanked with all my strength. Then across my drive to the left. If this had happened turning onto a highway someone could have been killed.

LATCHES/LOCKS/LINKAGES — Filed 11/01/2023

The door lock actuators have failed on both the driver side and passenger side front doors. Unfortunately this is a know issue across this model along with others and can be found in several forums. The problem is that the actuator gets stuck and at one point I was locked inside my car and once I was locked outside my car. If there was an emergency it could put mine and others safety at risk if the lock fails. The vehicle was inspected by Toyota who stated the actuators need to be replaced at $805 a piece and will not fix it themselves even though it is a known problem. This happened within the last month.

AIR BAGS — Filed 03/28/2023

My 4 runner was hit on the passenger side while crossing a intersection. The truck that hit my 4 runner was going at least 40 miles per hr and was a heavy duty pickup truck. On impact the airbags did NOT deploy but the 4 runner went haywire.

STEERING — Filed 02/08/2023

Steering shudder at 58-70 MPH has become almost unbearable. No warning lights whatsoever - ever! Vehicle has had this issue since 30K miles (110K currently) and Toyota always is "unable to replicate the issue" or tells people this is common on the 4 Runners and Tacoma's. I won't go to dealers anymore since Toyota knows it's a problem and they direct the dealers not to report to keep the issue cluster diluted. Any visible wheel shake, no matter what speed should not be considered "common". Just replaced all 4 tires with Pirelli Scorpions, did the recommended Toyota road force balance and had everything aligned. Doesn't drive any differently than with the old tires and out of alignment. Perhaps if the Toyota brass had to drive their OWNfamily in this vehicle, they would take a different position. Guess it will unfortunately take some highway fatalities in these vehicles before manufacturer or governments act. I'm praying for a class-action suit as there are 1000s of 4 Runner customers experiencing the same issue. Many of whom have sold at a loss just to get away from an unsafe vehicle. First Toyota I've owned and it will be the last.

Three of the four locks do not work on a consistent basis. The fourth lock works on occasion. Neither the key fob or the actual key will open the doors on the vehicle. The front driver door lock was replaced while under warranty, but broke again in under a month. The front passenger door lock was replaced at an out of pocket cost, but it also in a stopped working in a matter of weeks. There are times when the only access to the vehicle is through the trunk. The safety for all passengers is at risk because you cannot enter the vehicle in case of emergency or even on a daily basis. Also, the locks may not work when you are inside the vehicle and need to exit. This is an extreme safety issue in case of emergency. The locks have been replaced twice and the dealer acknowledged there is an issue with this year and model. The locks were inspected by the Toyota dealership when they had to be replaced. It is a well known defect which is commented on countless vehicle websites. There were no warning messages, the locks just stopped working. The date listed below is an approximation. I am aware of the year.
