The contact owns a 2023 Toyota 4Runner. The contact stated that the driver's side door failed to lock using the key fob or the buttons on the door. The doors had to be manually locked and unlocked. The vehicle was taken to the dealer, where it was confirmed to be a known issue, and the locks were replaced. Shortly after the vehicle was repaired, the failure reoccurred. The vehicle was taken to the dealer, and the failure was confirmed; however, the warranty coverage only provided a repair for the driver's side door. The failure had occurred on the passenger door and the rear driver’s side door, and the repairs were not covered under recall or warranty. The vehicle was not repaired. The manufacturer was informed of the failure. The manufacturer referred the contact to the federal safety agency Hotline to report the failure. The approximate failure mileage was 77,000. The VIN was not provided.

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.

After adjusting the vehicle lock sound level in the settings, it completely disabled my key fobs and the panic function on the key fob. Had to take to dealer to fix. Dealer had never seen the issue before. Been reported online many many times. Dealers and Toyota refuse to acknowledge a known issue.

When modifying the "Beep" volume which is tied to the audio beep when locking or unlocking the car, the car will then turn off the wireless ability read the key fob when using it to lock or unlock the car. The proximity feature will still function and you are still able to start the car. But you will lose functionality with all key fob buttons; lock, unlock, and panic will not be functional. This is listed in detail in the this 4Runner forums group. [XXX] This has been a known issue since 2022 and is still an issue. Toyota does not acknowledge this is a recall or an official issue. Every time an owner makes this change they are required to bring the vehicle to the dealership for them to re-enable the wireless key fob. This is an issue and must be resolved. I have access to modify my vehicles info on my own as my brother is a Toyota Tech and has the ability to do so. Please look at the forum link, there is greater detail of this issue occurring and 100s of accounts of owners reporting the issue.

I do not know what component or system failed. I was at an appointment with my son when the receptionist informed me that my car alarm was going off and there was smoke coming out of it. I went out to investigate and it sounded like the engine was attempting to start continuously. My key fob would not unlock the car. The engine continued to attempt to start and i was certain the car was going to start fire. We called 911 and went back inside to avoid anyone being hurt. The car then caught fire and burned until the fire department put it out. It was towed to an impound lot where it caught fire again and was destroyed. See pictures for more information.

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. My car got broken into because the locks don't work. I just replaced three of the four locks for around $1,200.00. Neither the key fob nor the actual key would open the doors on the vehicle. This is an extreme safety issue in case of emergency, and it really makes me mad. It is a well-known defect which is commented on countless vehicle websites. There were no warning messages, the locks just stopped working.

The contact owns a 2019 Toyota 4Runner. The contact stated that while attempting to lock the doors with the key fob, the front passenger’s side door failed to lock as desired. The contact took the vehicle to the dealer who diagnosed that the actuator failed and needed to be replaced. The vehicle had been repaired. Shortly after the repair, the front passenger’s side window failed to lower and raise. The contact returned the vehicle to the dealer and reattached the window’s wiring harness due to the harness detaching. Shortly after the second repair, the same window failed again and the lock on the driver’s door failed to lock. The contact had not taken the vehicle to the dealer yet. The manufacturer was not made aware of the failure. The approximate failure mileage was 40,000.

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.

I own a 2014 toyota 4runner ltd. I also own a 2011 toyota 4runner ltd. One vehicle is driven by myself, and the other is driven by my spouse. Each vehicle has its own key fob with push button start. When my spouse is traveling with me in the passenger seat of my vehicle, my key fob is not recognized, warning lights are displayed on my console and my vehicle does not start. My vehicle will start at times when I place my key fob next to the push to start button or request my spouse to stay outside my vehicle. However, when traveling with me, the warning lights are on and will prevent a startup in the case of an emergency. The same thing happens when I am travelling as a passenger in her vehicle (the 2011 toyota 4runner).
