Electrical System Problems of Toyota 4Runner - part 2

The rear window exploded on it's own with glass shattering everywhere while the defrost function was on. This is a very serious safety issue and design flaw that should be remedied before it happens. Toyota acknowledges the design flaw yet allows this dangerous occurrence to happen with consumers before doing anything about it. They say to bring it in for inspection but nothing that they can see until it has exploded. Toyota customer service representative named ryan informed me today there is nothing Toyota can do for me. They need to reimburse consumers for replacement no matter the time frame because it is a serious safety issue and it is a design flaw!.

Sometimes back-up cameras doesn't turn on while shifted in reverse. I have to shut engine and lift rear gate and close then it works again sometimes. When I am busy I just have to back up without the camera. That could leave drivers at increased risk of a crash when they back up without checking their surroundings.

2006 4runner rear glass exploded/shattered after using defrost - was denied reimbursement despite this being a known issue and faulty defrost connector. After dropping my 5 year old son off for school on 1/15/2021, I pulled up to a stop sign and heard a loud crash from the back of the car. I looked in the rear view mirror and the back glass had completely shattered and pieces were coming off into the back seat. Nothing had hit the window from the inside or outside - this happened spontaneously. Right before this happened, I had the rear defrost on for approximately 10 minutes to clear the rear glass while driving. The defrost was off when the glass exploded. I contacted my local Toyota dealership who informed me that this was a known issue but that the extended warranty coverage for this had ended on April 30, 2018. Toyota released a TSB (technical service bulletin) and offered an extended warranty and free replacement for vehicle owners who experienced this problem starting in 2017 but is since expired. The connector for the defrost located in the rear glass is found to be faulty and can short out or overheat, causing the glass to shatter. Being that this is a major safety concern and thankfully my 5 year old son wasn't in the backseat at the time, avoiding injury from the glass, I decided to contact Toyota customer experience. A case was opened, however, they wouldn't offer any compensation or assistance with getting the glass replaced. We are without a vehicle until this can be repaired and I am now forced to pay for it on my own since Toyota isn't agreeing to help at all.

On my way to the grocery store, my back window blew out while driving. It was a very loud pop! which scared the daylights out of me! I looked in the review-mirror and the back window completely shattered. There was nobody around and I was driving too slow for it to have been a rock or debris. I was driving in san antonio texas near utsa blvd. In the turning lane, was in motion at a slow speed as I was pulling up to a red light. The mechanic at safelight auto said that it had to do with the electrical and saved the piece of where there was a short causing the blast. As I walked out the door, a gentleman asked if that was my Toyota as he was there for the exact same issue for the same year make and model Toyota.

The backup camera does not work consistently. While not moving and then shifiting into reverse, the screen does not change or changes to something other than the camera. It usually stops working after several stops and shifts into reverse. Sometimes it goes 2 or 3 days without displaying and then starts working again another day.

Purchased vehicle brand new with 18 miles on it. I get it serviced like clockwork and have never missed a maintenance appointment. A little over a week ago, the electrical locking system on the drivers side door stopped functioning. Toyota is telling me that there are no recalls and it will cost me almost $1000. 00 to repair. Now, the electric locking system for the passenger side door is not working and Toyota is still saying it is nothing they can do because there is no recall and the vehicle is no longer under warranty. This is not acceptable. One minute the locking system was working with no obvious signs that something was amidst, then all of a sudden, my 4 runner doors are not locking. Now the cost is double and they are saying that the other doors will soon follow.

My lock on one of my door panels has quit working, I see it is a common problem costing @500 a door panel to correct. This needs to be a recall.

The contact owns a 2016 Toyota 4runner. The contact stated that while driving at various speeds, the vehicle hesitated while depressing the accelerator pedal. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to a dealer where it was discovered that rodents had chewed through the soy-based wiring. The electrical wiring was replaced out of pocket; however, the failure had recurred twice. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was 29,922.

The SUV does not lock when I use the remote or when I try to lock it manually. I replaced the actuator in the driver side door which was the door that stays unlocked however to no avail. I am out a lot of money however I now believe there may be a bigger problem with something called bcm. I do not want to spend more money getting the issue diagnosed and repaired. This feels unfair to me that the locking system is broke and I risk the vehicle being stolen at such a young age of the vehicle.

Multiple times now while driving under normal conditions we have experienced the instrument panel going rogue. Abs, vsc, gas, check engine, all lights will randomly come on. The scary part is this most recent time it jumped the speedometer way up as well. Any help would be greatly appreciated!.

After driving 10 mins or so the radio will freeze up, turn off and then turn back on. It only happens within the first 5 to 10 mins. I just purchased my 4 runner a week ago. So I haven't seen it turn off more then once yet. Seems like a short circuit somewhere.

I had been driving for two minutes on a city road going approximately 30 mph, when my car suddenly stalled and all the indicator lights came on. Then the car started on its own and I was able to turn into a parking lot. Then the car stalled again and I noticed smoke coming out of the hood in front of the windshield. I put it in park and took the key out of the ignition. I got out of the car and the car restarted and stalled on its own a few more times after that. It also made a loud beeping sound that sounded like a car alarm but we don't have an alarm installed. The entire front half of vehicle was annihilated.

2019 Toyota 4 runner. Consumer writes in regard to vehicle stalling while driving and to the recall no. 20v-012. The consumer stated the vehicle stalled twice. On one occasion the heat seting changed and the dashboard lights went out. The dealer was unable to duplicate the failure.

I was driving my car on pooler parkway in pooler, GA on a city street in heavy traffic when all of a sudden a buzzer goes off and my dashboard immediately gives off multiple warning signals. Vasc trac, trac off, abs (I) brake. I immediately pull off to the side of the road and try to stop the car, but the brakes fail. This incident could have killed my whole family. I had to have the car towed. Chatham Toyota in savannah GA informed me that I was very lucky that I nor my family members were hurt or killed. They also stated to repair this would be $4,000. 00 unbelievable! Toyota should warn and inform all buyers of this!!!!.

I was driving at a speed of 50 mph on pooler parkway in heavy traffic and a buzzer went off. All of a sudden my dashboard gives off multiple warning signals: vasc trac, trac off, abs (I) brake. I do not know what the problem is so I pull off the road and try to stop the car, but the brakes fail. I had to have the car towed. Chatham Toyota in savannah GA tells me it's about $4,000. 00 to repair this. This failure could have killed my whole family.

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 NHTSA's interests, however, since a known design defect could very easily lead to the death of an individual trapped in a vehicle.

I was driving down the highway using my rear defroster when my back window shattered without cause, it sounded like a gunshot. The shock caused me and the driver behind me to both swerve almost causing two wrecks.

The lock actuator motors on 4 out of 5 doors have stopped working. Only the drivers and rear door have exterior key entry, this dramatically inhibits the access to the back and front passenger seats in the event of an emergency.

The door lock actuators fail at an alarming rate. My driver side door lock actuator failed after only 50,000 miles. This prevents the car door from locking, which is a safety concern during a crash or just to prevent forced entry.

Tl the contact owns a 2007 Toyota 4runner. After starting the vehicle, a high pitched audible alarm sounded and the abs, traction control, and emergency brake sensors remained illuminated. Also, when depressing the brake pedal to stop the vehicle, the brakes malfunctioned and the pedal traveled to the floorboard. The vehicle was towed to jim hudson Toyota (970 columbiana dr, irmo,SC) , but the cause of the failure could not be determined. The manufacturer was not contacted. The failure mileage was 111,000.

Tl the contact owns a 2008 Toyota 4runner. While driving 50 mph, there was an odor of burning wires and smoke coming from the steering area. There were no warning indicators illuminated. The contact coasted the vehicle to the side of the road and waited one hour. The vehicle was restarted and was driven to the contact's residence. The contact called victoria Toyota (located at 5 heitzinger plaza, seaside, CA 93955, (831) 393-3020) and scheduled a diagnostic appointment. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 185,000.

Vehicle was being driven on beltway and suddenly lost all power, braking, and steering capabilities. Emergency brake was used to stop vehicle. Vehicle was not able to be restarted. Phone attached via cigarette outlet was zapped. Manufacturer has failed to assume any responsibility customer has endured due to this total vehicle malfunction.

My rear window shattered after using the defroster. Once I got out of my car after parking it in my job's garage it busted on it's own. I found out that this has happened to many 4th generation 4runner owners but Toyota won't recall or extend the warranty for this issue any longer. Now I have to either never use my rear defroster again while living in colorado or risk it shattering again and hurting passengers in my car. I would have never bought the vehicle if I had knowledge of such a dangerous issue.

In February 2018 I discovered that the passenger side door lock was intermittently not locking and not opening. This was happening using the remote, the button on the door and when placing the the vehicle in drive when the doors are supposed to lock automatically. This could have been happening for a significant period of time posing a security risk to me, my passengers and cargo. Eventually the lock stopped working completely and I had in repaired at the dealer in March costing $500 . The dealer claimed there were no recalls or safety campaigns even though I can see many complaints about Toyota door locks on the internet. In June 2018 the same things began occurring with the driver door lock. The lock would be very difficult to force open or closed manually or with the key from outside. Again it posed a safety risk especially because it would be so difficult to force open in an emergency. I brought it to the dealer again and again the dealer claims there are no recalls or campaigns and this time it cost $600. I've had many cars and trucks for decades and never had to replace lock actuators never mind 2 within a few months. In January 2019 the rear passenger side door lock suddenly stopped working and now I have to go through the same thing. So this saga continues. This is obviously a serious manufacturing flaw and a serious security risk to drivers, passengers and belongings.

While driving down a city street we smelled something burning. We pulled over to a vacant parking lot and put the car in park, before we could get of the car the back window exploded into lots of small pieces. Luckily no one was sitting in the back seat because glassed landed in the back seat as well as the parking lot. We noticed that the defrost button was on at the time of the explosion. The weather was cool at approx. 47 degrees on January 3, 2019 around 8:45 pm. I did get the glass replaced by safelite. The window installer confirmed that the wires for the defroster had melted. I did call Toyota to report the problem, but they said it was beyond their extended warranty enhancement program deadline of April 30, 2018. Clearly Toyota is aware of the problem because they did offer prior to April 30, 2018 an extended program that would help to reimburse customers whose window exploded. No recalls were provided for possible window explosions for 2006 Toyota 4runners.

Vehicle was in motion on a city street on 12/24/18 when the entire system (engine, electrical etc. ) completely quit. I was near a stop light, so I stopped and restarted the engine and resumed travel. On 12//27/18 I was in motion in a parking lot and the entire system failed again. At this time no systems were operable including lighting and the vehicle did not immediately restart with the ignition key. After approximately 5 minutes the vehicle responded to the ignition key and restarted. I took the vehicle to a Toyota dealership and they did a diagnostics test. No issues were found during the test and they were unable to duplicate the complete system failure. They did and audio system update and I picked the vehicle back up on 12/28/18.

I was driving on Dec. 24th, 2018, turned on my rear defroster on, and within minutes my rear window exploded. The company, safelite, told me that the defroster looked like it shorted out and caused the damage. Attached is a picture of the defroster wires.

The front passenger side door will not lock or unlock. I am sure you can understand the safety hazards with this issue. This door will not lock or unlock with key fob or with the locking system inside the car.

The 4runner's electrical system shuts down completely while driving; as if someone was suddently turned the car off while driving then turned it back on. All dash lights, instrumentation, headlights, radio, etc. . . Shut down and then it restarts automatically shortly thereafter. This happens multiple times daily. It occurs both while the car is in park or reverse or driving usually below 555mph since much of my commute is city vs. Highway. It started with the radio head unit only then the issue has progressed to the entire electrical system. This should be investigated as this is a major safety issue and could lead to injury.
