Engine And Engine Cooling Problems of Toyota 4Runner - part 1

I am writing to formally report a concerning issue with my 2022 Toyota 4runner, which currently has approximately 22,000 miles. The vehicle is regularly serviced at a certified oil change facility, and during routine use, I noticed a puddle of oil forming in my driveway. Upon contacting the service center, I was advised to bring the vehicle in for inspection. The technician identified a crack in the oem plastic oil filter housing, which was causing engine oil to leak. I was informed that this is a known issue the technician has encountered on multiple Toyota vehicles equipped with the same plastic housing. To resolve the issue, I purchased a replacement oem aluminum oil filter housing, which the technician installed. Since the replacement, the oil leak has ceased, and there have been no further incidents. I am concerned that the original plastic oil filter housing may be defective or prone to premature failure, potentially leading to engine damage or safety hazards. I respectfully request that this issue be investigated and considered for a recall or service bulletin, as it may affect other Toyota owners.

My vehicle is rear-ended by a large earth mover branded as a kenworth. My vehicle was then pushed into another. After the initial impact, my engine went racing above 5,000 rpm. It was disengaged from the transmission. I switched my car into neutral, shut my car off and the engine was no longer racing when I restarted the car. Because of an engine racing, I am concerned about the potential that somebody's transmission would be engaged and it could cause serious further injury.

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.

My exhaust pipe rusted apart after the muffler causing the hot exhaust to expel upward and melt a rubber grommet on the floor. Then it proceeded to shoot into cargo area, melting the carpet backing and styrofoam pad and insulation under the cargo area carpeting. This happened on an 11 hour road trip with the cargo area full of vacation stuff. I'm concerned about this being a potential fire and carbon monoxide issue.

The contact owns a 2015 Toyota 4runner. The contact stated that on four occasions while diving at various speeds, the vehicle stalled. The vehicle was restarted after approximately 10 minutes after each occasion. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 143,400.

Two transfer case seals failed at 64,000 miles. Caused excessive oil to leak out of transfer case and onto the exhaust. Safety was put as risk by potential full failure of transfer case which can cause loss of power at speed or leaking oil on exhaust causing a fire. Problem was verified by armstrong automotive and repaired. No warning lights were present. Problem found after smelling burning oil and noticing smoking coming from underneath vehicle.

We purchased our vehicle new September 2023 from a Toyota dealership. Engine oil dipstick Toyota part 15301-50140 was installed in vehicle and was verified by 50140 stamped on dipstick. I wanted an extra oil dipstick so ordered a replacement through Toyota. The original dipstick part 15301-50140 is no longer available and has been superseded by Toyota part 15301-0p060. I ordered the new dipstick part number and received it from Toyota. It is verified by 0p060 stamped on the dipstick. The safety concern is the two dipsticks are not the same length and each one requires a different quantity of engine oil to reach the full mark. The new dipstick -0p060 is 1/2 inch shorter than the old, no longer available dipstick -50140. Most importantly the low and full marks are also both 1/2 inch higher up or closer to dipstick handle on the new dipstick than the old one. It takes approximately 0. 9 quart more of engine oil to reach full on the new dipstick than on the old one. One of these dipsticks is correct for my vehicle and one is not. The original dipstick is no longer available and the new dipstick is not the same as the original. The difference of 0. 9 quart more or less of oil in the engine is significant and important. Too much or too little oil can damage an engine or contribute to a shorter engine life. Both of these dipsticks cannot be correct for our vehicle. I have talked to the service managers at two Toyota dealerships and they do not have an answer for why these dipsticks are different. I have spoken to parts department people at two additional Toyota dealerships, called Toyota motor north America and no one has any idea why these dipsticks are different or which one I should be using. I also wrote a letter to Toyota motor na headquarters over two months ago and have received no response to date. I have both dipsticks available for inspection. Toyota needs to let owners know if they should replace their old dipsticks or not on these vehicles.

When I first saw the pictures on the internet, I noticed that the front underside appeared to have rust issues. (frontal shot) I contacted that sales person and he blew me off when I requested photos of the underbody. After several attempts, he finally sent a couple of pictures. The pictures obviously did not show the major rust issues as I have provided. The pictures were carefully fabricated not to show the major rust issues. It was apparent that the vehicle was taken off the internet while they hid the rusty underbody by applying some coating. A short time later, the dealership reposted the vehicle on their website. The vehicle was not properly advertised as having this major rust issue. I asked the salesman if his family was driving the vehicle, would he feel safe. He replied, "absolutely". With this said, I decided to purchase the vehicle. Also, my signature is not on the "we owe". Also, the vehicle has an exhaust leak from the manifold area. It makes a loud ticking noise. This is going to cost approximately $1,500 to fix. The air conditioner is not blowing cold and either has a leak or in need of freon. This is another repair out of my pocket. This is what kind of pre-owned vehicle they sold me. This vehicle should have never been listed for sale.

My gear shift became difficult to shift. As I was driving it, when I physically shifted to the drive position, the display didn't confirm "d", but I could drive. As I was driving, the car shifted to neutral without me shifting, but did not show "n" on the display. My car stopped accelerating and revved higher. This occurred as I was driving on the road around 45 mph. I could not tell on the display that I was not in drive. I pulled over safely luckily. I continued to try to get it to drive to get it to a dealership to look at. They reported it was prndl switch issue. Tech found internal corrosion in transmission range sensor creating a physical resistance in sensor which prevented vehicle from properly indicating gear. Tech replaced transmission range sensor, adjusted sensorwith techstream data list, and performed health check this is not the first they have seen either. This would appear to be a common safety issue to drivers. I also had a difficult time confirming the car was in the park "p" position. I believe this issue could have potentially affected the vehicle's ability to engage in park and stay in park, much like the issue with getting into drive and staying in drive.

The contact owns a 2022 Toyota 4runner. The contact stated that while driving at an undisclosed speed on the freeway, the vehicle lost motive power. The 4wd error and various other unknown warning lights and messages were illuminated. The contact managed to pull over and stated that smoke was seen coming from underneath the hood, and that once he opened the hood, there were flames coming from the airbox, and he pulled out the air filter. The contact stated that he managed to extinguish the fire. The fire department arrived after the fire was extinguished, and there was no report completed. The vehicle was then towed to a local dealer; however, the mechanic made the contact aware that the manufacturer would send out an inspector. The inspector made the contact aware of a faulty unknown sensor; however, the vehicle remained at the dealer awaiting further diagnosis and repairs. The manufacturer was made aware of the failure. The approximate failure mileage was 47,000.

Vehicle radiator light came on, shortly thereafter (5-10 min) vehicle overheated. Waited for vehicle to cool down, then drove home. The following day drove the vehicle to dealership. After an inspection the dealer stated the heads are cracked and needed to be replaced. When I asked how this could happen to a car that is regularly serviced with only 90k miles his response was "the original heads were made of weaker metal, the replacement ones are upgraded. We haven't had any come-backs on the ones we've replaced". I then asked, well how many vehicles has this impacted? sounds like this should be covered under a recall? his response "we've had quite a few in the past month or so, seems to be happening when vehicles get to the 70-80k range. " sounds to me like Mazda knew the heads were made from inferior products which is why they upgraded the part on newer models.

My 2019 Toyota 4runner was inhabited by a rat that chewed the wiring harness in at least 3 different areas. The damage occurred between 8pm and 7am. The vehicle started with lights on the dash illuminated. The car was out into drive and was jerking. Reverse had the same result. After inspecting under the hood of the car wires were seen chewed partially and a few completely severed. A rat was seen under the manifold cover. I used an air hose to evict it and had the car towed to dealership. The bill was just under $1000 to repair. I was warned it could have been worse ($6000) if harness needed changing. I was told “I was lucky”. After researching I discovered this is a problem because of soy based wiring. It’s an attractant for rodents.

Engine, no sign of overheating . . . Overheated within 3 months of ownership on my way to work with my wife's conclude the headgaskets were blown. Toyota doesn't acknowledge recall. . Plus send a recall for v6 4runners headgaskets.

The contact owns a 2005 Toyota 4runner. The contact stated while driving at an undisclosed speed, the radiator boiled over without warning. The contact stated that the failure was due to the head gasket. The contact called the local dealer however, the vehicle was not diagnosed or repaired. The manufacture was not contacted. The approximate failure mileage was 170,000.

While driving my 4 runner at about 45 mph, it just stopped working. Engine was still running but it would not go. It was like it was stuck in neutral. I pressed the gas all the way to the floor and nothing. I was stuck in the middle of the road and unable to go. About 30-45 seconds and it began to work again. I took it to newark Toyota and reported the problem but they said since they were unable to duplicate there was nothing they could do. They claimed maybe the floor mat got stuck under the pedal- it is a secure floor mat and I am positive the floor mat was not in the way. I was able to push gas pedal all the way to the floor with no movement of the car. Also I was already driving the car without any issues before it completely stopped working. I am just lucky it didn't happen on an interstate - as I would not have been able to get out of the way of fast moving traffic.

Make: Toyota model: 4runner year: 2013 mileage: 76,200 description of incident while driving on [xxx] at night, the vehicle experienced a sudden and catastrophic engine failure, leaving it immobilized in the middle of the highway. This presented an immediate and severe safety risk to both the vehicle occupants and other motorists. The failure was later determined to be caused by a malfunction in the variable valve timing (vvt) oil control system, specifically an exhaust cam gear failure. This led to a broken timing chain and subsequent engine failure. Inspection and diagnosis the vehicle was inspected by an authorized Toyota dealer in florence, SC. They confirmed the failure of the oil control system and recommended a complete engine replacement, estimating costs over $5,000. Broader implications and potential safety hazard further investigation, including consultations with multiple Toyota technicians, review of technical discussions on various platforms, and examination of online 4runner forums, suggests that this issue is not isolated. Failures of the exhaust cam gear and problems with the vvt oil control system appear to be common in the Toyota 1gr-fe engine and other engines equipped with this system. It's noteworthy that Toyota issued a voluntary recall in 2014 (safety recall 13v-395, tm-tc-14021) for Lexus vehicles with similar issues. However, this recall does not appear to cover the 2013 1gr-fe 4runner engine, despite the apparent similarity in potential failure modes. Safety concerns this issue presents a significant safety hazard: sudden engine failure at highway speeds can lead to loss of vehicle control. Unexpected vehicle immobilization, especially at night or in high-traffic areas, poses a severe collision risk. The apparent widespread nature of this issue suggests that many vehicles may be at risk of similar failures. Urgency for action given the severity of the potential outcomes and the ap information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact stated that while her mother was driving 5 mph, she heard abnormal grinding sounds and the vehicle inadvertently stalled. An unknown warning light was illuminated. The contact was unable to restart the vehicle. The vehicle was towed to the dealer for diagnostic testing. The contact also stated that she had smelled a strong burning odor while driving and the subframe of the vehicle was corroded. The manufacturer was notified of the failure and a case was opened. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 15,000.

The 4runner hesitates at 40mph and 60mph when trying to coast/maintain speed with slight pressure on the gas pedal. At other speeds or while accelerating at 40/60mph there is no hesitation. I took it to the dealership, but they said they can't replicate the problem. It is still happening though.

My husband parked the car on a hill in front of a gas station and I stayed in the car sitting on the passenger seat and it just rolled down the hill, caused an accident to a parked car getting gas, I jumped out of the car as it rolled towards a gas pump , slammed on to pump guard. Thankfully no one was hurt but me when I jumped out of the car. Police report filed.

"takata recall". So I'm not understanding a problem with my Toyota 4runner. As of yesterday there was a great amount of smoke coming from the area of the oil stick from my assumption the oil was getting on the Cadillac converter. Or something that would hit something hot on the engine to cause it to smoke I'm trying to find out if there is a recall for that.

First, the motor blew for no reason at 152,000 miles. I rebuilt the car and had a new motor put in. I was not aware of the rusting frame issue, however, after driving the vehicle with a lovely new rebuilt motor for about one year, the frame rotted beyond repair causing the power steering to go out. I don't drive much, so there was no excessive exposure to salt. The car was parked in my driveway. It was an exceptionally cold day. I started the vehicle and found the power steering fluid had frozen and lost all the fluid as a result of the steering rack being rusted and weakened. The repair shop told me that the frame and rocker panels are severely compromised too badly to bother fixing the steering rack. The car is not safe to drive.

Tl the contact owns a 2013 Toyota 4runner. While driving 30 mph, the check engine and track off 4 low indicators appeared. While driving approximately 30 mph, the transmission erroneously switched into the neutral position and the vehicle would no longer accelerate. Also, while operating the vehicle, the instrument panel would not indicate that the transmission was in the neutral or drive positions. The vehicle was taken to graham auto mall (1515 west 4th st, mansfield, OH) where it was diagnosed that the neutral safety switch was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 96,837.

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.

While driving along at slower speeds the engine seems to quit for about 5sec then it comes on again. This is a dangerous condition. This could happen anytime.

Kings Toyota dealership informed me that the frame is rusted so severely that it is unsafe to drive the vehicle. Service technician says rust is so bad they cannot put it on a lift. .

Had a misfire in #6 cylinder at 155k miles. I took it to a dealer and they told me that I had a head gasket starting to go bad that let coolant into that cylinder after I shut the engine off resulting in a rough cold start. The tech specialist gave me some nice information and after research I learned Toyota knew about the faulty head gaskets in their vehicles and came out with a new redesigned one, but they never told consumers and refuse to fo anything about it. Now my car is in the shop and quoted at $3200.

Tl the contact owned a 2011 Toyota 4runner. While driving 25 mph, the contact noticed smoke coming front the vents inside the vehicle. The contact pulled the vehicle over to the side of the road, checked under the hood, and did not detect any smoke. The contact opened the driver's door and saw flames coming from the center console. There were no warning indicators illuminated. The contact was not injured. A police report was filed. The vehicle was destroyed and towed to an unknown location.

The failure mileage was 137,000.

The Toyota secondary air system has failed rendering my car without traction control. . . And other lights. There is no preventative measures for this part and Toyota used the exact same system on the tundra's and sequoia's with the same problem I'm having. This needs to be addressed as the repair for the system is roughly 4000. 00 almost half the cost of my car. . . Please make them fix this on all cars where the same system was used.

I'm a retired master mechanic turned aerospace engineer. On Aug 24, while my foot was on the brake, the engine revved to full throttle, squealing the rear tires. This event was clearly caused by a faulty electronic throttle control circuit. I shut off the truck. When I started it again, the situation was still there. I shut it off and waited 10 seconds, then started it and it idled normally. I concluded that there was a software glitch. This happened once before about two years ago. In both cases, my truck was luckily stopped in a parking lot with the transmission in drive.

The secondary air injection pump is sending error messages and the vehicle is now in limp mode. The vehicle will not go over 30mph.
