Electrical System Problems of Toyota Tacoma - part 2

The cabin vent system appears to have a design defect, specifically the passenger-side vent located in the back of the cabin. This component is available for inspection upon request. The dealership, santa cruz Toyota, has declined to replace the part despite acknowledging the issue. The concern lies in the vent's design, as it allows water to enter the cabin instead of just expelling air. The water intrusion caused by this malfunction poses a safety risk in two ways. First, the presence of water on the floor increases the chance of an electrical fire due to the numerous electrical wires running underneath. Second, mildew spores can grow on the wet undercarpet padding, creating a health hazard. This problem has been confirmed by santa cruz Toyota, and we have video evidence to support the claim. While santa cruz Toyota has inspected the vehicle, our request for a direct inspection from the manufacturer, Toyota, has not been successful. There weren't any warning lights or messages prior to the failure. However, the issue became apparent after the heavy rains of 2023 in California, when we discovered water accumulated under the passenger-side carpet padding.

This Toyota Tacoma's soy based wiring attracts rodents and I have had to have repairs for the wiring. My 2 other older vehicles in the same location that does not have the soy based wiring there no problem. This is a world wide issue and no one has done nothing about. This is a safety issue that can be potentially dangerous, if some of the safety systems fail due to soy based wiring attracting rodents.

I currently own a 2019 Tacoma with around 70,000 miles on it. I keep up with all the Toyota recommended maintenance services to make sure my vehicle is well taken care of. So, while driving the vehicle on the interstate it drastically slowed down on its own and I could not get the gas pedal to engage almost causing a rear end collision. This also happened on two other occasions at lower speeds. My display stated I was having issues with abs, collision, and that I was pressing the gas pedal and break at the same time. My vehicle has been at the dealership for 4 days now with no resolve or any answers to why the vehicle is slowing down on its own. I feel the vehicle is a health/safety issue and I will not drive it until the issue is resolved. The computer was also flashed by Toyota a year earlier as I was experiencing a lag in engine engagement and high rpm's when the vehicle shifted from first to second gear. Something the tech noted he experienced driving it. It's also an issue I've had since purchasing the vehicle. I had to bring the vehicle back a month later as it started doing the same thing but was told they could not find any issues. I have found many other forums and spoke with other Tacoma owners who have had similar issues. I feel Toyota is definitely aware of the issues but not addressing them! I hope to get some answers soon!.

Trac off & engine lights came on. Removed gas cap and put it back on. Removed cables to the battery and left them off. Replaced battery cables. Lights remain on. Went to dealership and they charged $100 to scan vehicle. They don't know what's wrong and said it'd be another $800 to check further. They said maybe a rodent had chewed through a cable??? have seen several reports of this vehicle condition and the battery cable resetting took care of the problem a lot of the time. Not this time. Don't feel comfortable a. Driving the truck with these lights on and b. Don't feel comfortable with handing over $800 for them to look into it. What to do?????????????.

Vehicle is designed in such a way as to allow moisture accumulating in drivers side floor mat and carpeting to wick upward and be deposited on the primary vehicle wiring harness located in the drivers side kick panel. The moisture collected travels down into the backside of the various female connectors and corrodes the conductors and receptacles that result in short circuits between the various vehicle components including the ignition, engine shutoff, temperature sensors, antilock breaking, blind spot monitoring, fuel gauge, forward vehicle lighting (high and low beam), security, traction control and other critical vehicle systems. On February 5th, 2023 I returned to my vehicle to find the security alarm sounding in the parking lot of a local business, both the keyless entry system and key-fob were unresponsive and would neither silence the alarm or unlock the vehicle. After manually unlocking the door handle the alarm ceased, the vehicle started as normal and then began indicating a failure of the bsm system, while underway the abs indicated it had also failed and upon arrival at our destination the engine would not turn off even with the emergency shutdown routine prescribed for unintended acceleration cases. In addition, the high beams would be triggered by unrelated button operation occasionally fail to turn off, the fuel gauge, temperature readouts and climate control provided unintelligible values. The vehicle was returned to to dealership where it was determined that water from the floormats was able to contaminate and cause systemwide failure. The repair was to replace the entire wire harness which would not be covered by warranty. On 3/15/2023 I reached out to Toyota headquarters' customer engagement team and was advised that Toyota was aware of the problem and had no interest or obligation in rectifying the situation, regardless of my concerns that this presented a clear safety hazard to both operators and the general public.

The airbag light first came on about 60 days ago, the first time I tried to use the cruise control after light was first noticed the cruise control did not work. My concern is that as long as the light is on the airbag(s) may or may not deploy. This airbag light has stayed on constantly since first appeared, the cruise control will work intermittently. The component has not been inspected but there is a recall, 12v092000:air bag clockspring replacement, that addresses this exact concern but appears my VIN is not included. This is obviously a problem on other VIN ranges because mine suffers from this and it is obvious Toyota is aware there is a problem but it just hasn't had enough complaints with my VIN range, likely because there are not as many on the road as the vehicle is 14 years old. I am concerned for my family's safety as well as my own if the airbag fails to deploy because of an accident.

Driver’s side front seat not delivering heat despite switch lamp indicating it’s on and working. Further exploration reveals passenger side seat heater working as it should. I checked wiring harness and connections under driver’s seat only to discover plastic connector entering amplifier scorched and melted with two of four pins destroyed (red and green wires). I believe the wire gauge sized for this system is improper and therefore represents a fire hazard. About the time the seat heater failed, I smelled a burning odor inside the car for a short time but didn’t associate the two events until later. The vehicle has 135,998 miles on it and therefore out of warranty. I spoke to the dealer who explained he’s had similar issues from other customers and added there is no recalls at this time.

The contact owns a 2023 Toyota Tacoma. The contact stated that while reversing, the rpm and engine surged while turning the steering wheel. There were no warning lights illuminated. The vehicle was taken to the local dealer, who informed the contact that there was no coverage for the failure of the vehicle. The vehicle was not diagnosed or repaired. The contact related the failure to TSB: 0125-18. The manufacturer was contacted and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 300.

I purchased my vehicle (Toyota Tacoma trd pro) on September 23, 2022 and identified issues with all of the exterior cameras immediately. I scheduled an appointment with Toyota to inspect the problem with blurry cameras on September 29, 2022, but they advised that all 2022 vehicles have similar blurriness issues. I also own a 2018 Toyota highlander that has a much more crisp image, so I know Toyota has a problem with the cameras. Fast forward to approximately November 20, 2022 when my first problem occurred. I was backing into a parking space that had a shopping cart that was left on the sidewalk behind my parking space. Knowing that I was clear to park, I proceeded to back into the space, but as I started to back up, the already blurry camera flared up because of the direct sunlight and I could not observe anything. It so happens that the shopping cart started to roll towards my parking spot and hit the bumper of my truck, because of the high tailgate I was not able to observe this moving cart in my mirrors. Because of the flared and blurry camera image, I could not see the cart and the minor collision occurred. There was no damage to either my truck or the cart, but this could have been a child or animal and could have resulted injury or loss of life. As I have learned, this particular camera cannot be relied upon for the safe viewing behind the vehicle as it was intended. As my vehicle is equipped with multiple front, side, and rear cameras and they are all blurry, I would presume the problem lies somewhere with the computer or image controlling board that the cameras are attached to. This issue has not been inspected by the police or insurance company as no loss occurred and there were not faults indicated on the vehicle. Toyota did state that this was the normal operation for all 2022 vehicles and I presume this is a widespread issue what will inevitably have dire consequences down the road. Please evaluate and encourage Toyota to produce a fix.

The contact owns a 2004 Toyota Tacoma. The contact stated while driving 20 mph and making a right turn, the vehicle lost motive power and stalled. There was no warning light illuminated. The contact was able to veer to the side of the road. The vehicle failed to restart after several attempts. The vehicle was towed to the dealer, where it was diagnosed that the electronic fuel injection (efi) main fuse had blown due to a short circuit. The dealer replaced the electronic fuel injection (efi) main fuse; however, the failure persisted. Additionally, the dealer diagnosed that the subframe was severely corroded, including transmission components and fuel system components. The manufacturer was notified of the failure and informed the contact that they could not assist as unknown recalls had expired. The vehicle was not repaired. The failure mileage was approximately 150,000.

While driving down the road with my driver seat warmer on, the heating element and/or associated electronics burned a hole in the seat canvas and through the jacket I was wearing. I think a small fire started which I put out with my finger and then I turned off the seat heater.

Iq wireless charging pad gets hot pad has bubbled and dislodged from its place. Pad was replaced already for the same issue in Feb-2020. Now the same issue is recurring. The dealer said they had seen many more vehicles with the same problem. Charging pad gets hot when not in use. I contacted Toyota customer care to report and ask for advice, and they just said thank you for your feedback vehicle is out of warranty nothing we can do about the issue. Explained this is an ongoing issue through this style of vehicle and should be noted or looked into as a possible safety concern. They said thanks for the feedback.

System failure lost all directional and hazard lights on this vehicle . With no directional signals can cause a serious accident. Vehicle is at dealership. Component has not been inspected by the manufacture . No warning just stop working. This vehicle has no separate flasher relay. Toyota did not honor the last request to fix a electrical issue. Should be a recall for this issue as other Toyota Tacoma owners had the same issue.

This VIN number was totaled due to a bent frame after being rear ended on June 10th. I fear my insurance company (usaa) will attempt to commit fraud by not reporting the title as salvage.

First notices that volume control on steering wheel and temp and directional display stopped working about a year ago. Now air bag light stays on when car is started and alarm for seat belts quit working.

My problem was associated with the air bag warning light. It came on and so I took my truck to big two Toyota in chandler az. Dealer said I had a faulty clock spring assembly that will prevent the air bag system from functioning properly and was a major safety risk. . . . So I let dealer remove and replace it for $511. 82. This should have been safety recall. . . . Please look into this issue for me and other Toyota Tacoma truck owners. Thank you.

The driver's side seat heating element failed due to a defective seat heater amp. When independently researching the failure, which could have simply been an unconnected wire, I discovered the amp and wiring had an electrical seizure and the wiring had burned the amp. The heating amp sits underneath the seat and with the right conditions could cause the seat to catch fire. The issue has been reported to Toyota corporate.

Pcs malfunction, vsc malfunctions, data transmitter for codes to dealership doesn't work, transmisson jerk/lost in gears, from stop to go would jerk into gear, hot air comes out of steering wheel (video proof), air coming through window controls. When the pre-collision system had its malfunction the truck took complete control which gave me no access to breaks or gas, when pcs system kicked off truck jerked really hard & started accelerating on its own causing very high rpms then just stopped accelerating. Transmission would occasionally seem to have an improper shift & jerk.  I took my vehicle to Toyota of denton for the 5k service, & stated issues with the pcs & vsc malfunctions shown on the dashbord.  denton dealership said don't worry we will take care of it. The itemized reciept doesn't show issues were looked at; & I kept having the same issues. So I took my truck back to the denton dealership 2nd time & was told "no malfunction light so no ssues were there" by the service manager. Who also said "the truck sends malfunction codes to a computer at the dealership, but no codes were sent. " which made me feel like there was more wrong with the truck, including electronics, data sender/reciever, & vehicle alert system relay via dash board aswell. Contacted corp. Informing them of my issues & concerns making it the 3rd time trying to resolve ongoing issues & requested a field inspector from corp. Look at it instead of a dealership. When complaining to corp. I stated hot air comes from the steering wheel after 1 hr driving it. Field inspector only drove it 45 miles & said nothings wrong with it. I drove this truck for 8,557 & he didnt find anything wrong in the little 45 mile test; yet the black box showed several pending codes on my truck & also the inspectors truck which is the same year & model. Black box data shows pending code on 1/12/21, 4 days before I acquired it; none again until 2/6/21 & then pending codes at least twice a month until 11/22/21. Bbd pic proof.

I was my 2021 Toyota Tacoma home after work on the highway at night at 11:00 pm. While on the highways there was highway construction and traffic was coming to a stop. I was driving in the slow lane doing 60-65. As I approached the stopped traffic I let my foot of the accelerator pedal and put my foot on the brake pedal to slow down, as I did this the rpm's jumped up to 4000 and the truck went to take off full speed on its own. I held the brake pedal down to the floor and I shifted the truck from drive mode to sport mode than back to drive mode. ( I panicked) but soon as I did that the engine stopped accelerating thankfully because I had many stopped cars in front of me that I would have plowed into. I love my truck but I am not scared to drive it always have my hand on the shift waiting for it to happen again possibly.

The high mount rear stop lamp leaks water into the cab. The water channels in through a cheap gasket, down the inside of the frame, destroying the cushions and plastic through moisture and mildew. Toyota corporation and precision Toyota of tucson (service) az, both say the problem is only covered by the regular 36,000 mileage, 3 year warranty. They want to charge me $575 to replace the light. However, the known issue doesn't occur because of miles driven or even age of the vehicle. I live in the desert and it has not rained significantly since I bought the truck new in 2017, according to the national weather service. This year, with record rains, water is freely seeping in to the cab. Toyota should recall Tacomas with this issue and replace the cheap gasket it used to manufacture these trucks.

Vehicle has been jerking itself while driving at both low speeds and high speeds. Had taken it to the dealership sept. 2020 in order to get the ecu/pcm reflashed/updated to resolve issue; issue persists. Now, at highway speeds, 80% of the time it will be jerking itself, as off being momentarily shut off and on. Caused my rear end to fish tail on highway.

I was driving my truck a 2019 trd off road Tacoma from san diego to la I was on the 605 freeway in the fast lane when I noticed smoke smell and then I noticed fire flames by the air conditioner and the phone charging plate I proceed to exit the freeway thankfully I did not get in a car accident with any other vehicles however I was unable to stop and put out the fire. It's very upsetting because at no fault of my own I am now lob obligated to find another vehicle and I am not in the financial or credit position that I was when I bought my truck that is now a total loss by my insurance it covers my loan but not much after that so the fact that I've heard that this has been an issue for a few other Tacoma's and it's not even listed yet there's a problem the fact that this is not within my control as to what happened and there's nothing but OH well good luck getting another car something needs to change.

The check engine light will not go off. A Toyota independent service/repair facility checked everything and said it is electrical board problem. I rec'd a safety recall letter from Toyota stating there is a malfunction indicator lamp causing the check engine light to stay on. It states I will receive a 2nd notification when remedy is available that I have not rec'd. They want me to pay the dealer (approx. 300-400 dollars) then send documents of repair to Toyota corp for reimbursement! I do not have that kind of money to wait and see if I will be reimbursed. Why are they dragging their feet not sending an actual recall that they will pay their dealers after they perform the work? why is this recall not noted above. Are they trying to not have to do anything? in red, the letter states "this is an important safety recall:" but the Toyota dealer "team Toyota" knew nothing about it,said they could check and fix, but would have to pay for it then maybe be reimbursed by Toyota but they couldn't say I would be. Can you help with this?? my email is r_mrains@yahoo. Com thank you mary rains (retired don't have access to send documents,I could take picture with phone and send to phone #).
