The power door lock actuators on both front doors of my 2021 Toyota 4Runner have failed. The problem developed progressively. The front door locks initially began working intermittently and became less reliable over time. Eventually, both front door lock actuators stopped operating. They have now been inoperative for more than six months. The front doors will not reliably lock or unlock using the vehicle's power locking system or key fob, while the rear power door locks continue to operate normally. I discussed the problem with a Toyota dealership and was told by dealership personnel that they have seen this door lock actuator failure happen countless times. Despite the apparent frequency of the problem, I am not aware of a recall covering my vehicle. I am concerned about the safety implications of multiple door lock actuators failing prematurely. The failure prevents the vehicle's power locking system from reliably securing or unlocking the front doors and could cause difficulty quickly unlocking a front door for a passenger or occupant in an emergency. There were no warning lights or dashboard messages before the failures. The primary warning was the progressively intermittent operation of each front door lock before it stopped functioning entirely. Both front doors experienced the same progressive malfunction. I am reporting this because the failure has affected multiple actuators on the same vehicle, has persisted for more than six months, and a Toyota dealership indicated that it has encountered this problem many times.

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] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
My vehicle: 2003 4Runner SR5 2WD VIN: [XXX] Issue: Front driver's side door will not open. Electronic locks are operating, but the door release is not functioning. Safety Concern: What if I was in a situation where I did need to get out of the vehicle immediately? Such as a high-water incident, fire, etc. Especially for a person [XXX], as myself, this would be a big issue. When attempting to exit the car after pulling into the driveway, I could not open the driver's door. The locks would release, but the door latch would not. I had to crawl over the console to get out through the passenger side. This was not easy as I had back fusion surgery and 8 disc replaced, fused. I had to open the sunroof to help with get over and out. After I did get out, I tried the key in the driver's door, it would actuate the door locks on all doors, but the driver's side door latch would still not release. I even disconnected the battery and reconnected. No help. And after knowing more, it was not an electrical issue, but mechanical failure. I now have it at the repair shop after talking with Toyota Service manage who admitted it was a poor design as the repair for this is to destroy the door panel to get to the actuator to attempt to release the door latch. The estimate for this work is 1,150.00. I am beyond frustration, and especially when I see there is no recall for this issue. There are penty of conversations on this same issue on 4Runner forums as well as all over YouTube. Thank you for looking into this.

I have owned my vehicle since 2017 and since then I have had to change the locks over 10 times. this has been ongoing since purchasing my car. Some were originally covered with the warranty but since it expired, i have paid dealerships out of pocket. I have a lock give out almost yearly. Right now my car has 3 of the 4 door locks not working and the 4th just started acting up as well. I have checked for recalls because it doesn't make sense that they would go out yearly and the dealerships have even told me there should be recalls because my year 4runner always has lock issues. my safety concern is my locks either have to stay unlocked or i risk locking my car completely and it not opening because the key will not unlock it. I have tried contacting Toyota and they have stated they cannot help so I am wanting to reach out to see if there is anything that can be done or if you can point me in the right direction on who i can reach out to . thank you
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.
The contact owns a 2002 Toyota 4Runner. The contact stated while pulling the door handle to unlock the doors, the auto unlock function failed to unlock the doors. The contact had to press the unlock button to unlock the vehicle. The vehicle was taken to the dealer to be diagnosed and the dealer stated that a failure was not found. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 150,000.
1) The failed component is the door locks. Or more precisely, the motor for the electrical operation of the door locks. When failed, the door remains locked even when pulling on the interior handle to open the door or when trying to unlock the door using the interior latch. You are essentially locked inside your car. I believe the door should always unlock when the handle is pulled, and the interior lock lever should always unlock the door as well. Both of these function "normally" when the actuator is not failed. The failure first appeared in late 2018/early 2019. I noticed that when I locked the vehicle using the key fob, I was not hearing the audible "beep." And when the car was shifted out of PARK, I was not hearing all the doors lock. I then realized the drivers front door was not locking. I lived with this for a while, long enough for the drivers side rear door to fail, and then the right rear door failed as well. The front right and rear door have never failed. I purchased a Toyota lock assembly for the drivers side front and it functioned perfectly after replacement until this past week. It appears to have failed again. And I was essentially trapped in the drivers seat. I had to give it and electrical command to unlock while pushing on the manual lever in order for the door to unlock. Pulling the open handle did not open the door, and pushing on the manual lock lever did not open the lock. The failed component appears to be a small motor in the lock assy. I replaced this motor in the left and right rear door lock assembly's and that corrected the problem. I am going to replace the motor in the lock assy I removed in 2019 and reinstall it in hopes of correcting the problem. I can send you the Toyota lock assy I will remove, and one of the motors I removed from one of the rear door lock assembly's. 2)The failed door locks trap occupants inside the vehicle. 3)Did not visit a dealer or repair center. 4)No inspections have been performed. 5)No
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.
Toyota has a major safety issue (that they know about) relating to door lock actuators on their 4runners. Both of mine (passenger and driver side) failed within the first 55,000 miles, and there are a LOT of others who have had the same problem. The forums are littered with people reporting. However, Toyota has discouraged people from reporting the problem to them by charging an exorbitant amount for repair of such an inexpensive item (about $800 per side). When that becomes known to owners, people will just repair the items themselves. This is obviously unethical. Door lock actuators pose an obvious safety issue, both if the door remains unlocked when it is supposed to be locked, and when the door remains locked when it is supposed to be unlocked. In the latter case, following an accident where a passenger is incapacitated and the door lock cannot be reached by hand (and there's no external key slot), the only way to unlock the door is via the electronic fob. If the door lock actuator is broken, then that incapacitated passenger will be trapped in the vehicle. For the former case - and this has personally happened to me - when the door was supposed to be locked, I had an individual actually open my passenger side door and enter into my vehicle. (He was under the influence of something, and fortunately nothing happened other than a very tense situation). But the safety issue remains. I expect that the post-accident scenario is more relevant to the federal safety agency's interests, however, since a KNOWN design defect could very easily lead to the death of an individual trapped in a vehicle.
Having major problems with door lock actuators. just replaced front passenger side for 950 dollars at Toyota dealer and was told the other 3 doors may start failing as well. I did not realize at first that the door was not locking which would make it so easy for someone to break into my car.It is a 2014 Toyota 4runner. Sure enough the front driver side door is not locking. I need to spend another 950 dollars to get it fixed. What is wrong with these actuators? Now the replacement actuator I had put on the passenger side is giving me problems with the door opening and closing. What next?? Toyota should definitely have a recall on these actuators. It appears that I am not the only one having problems. This is a security issue.
