Electrical System Problems of Toyota Tundra - part 2

What component failed and is it available for inspection? the front driver-side roof seam on my 2022 Toyota Tundra developed corrosion under the paint and eventually opened enough for rainwater to enter the cabin. Water drips directly into the a-pillar area onto the side curtain airbag wiring, squib connector, and padded harness. It also reaches the dashboard and electrical buttons near the steering wheel during rain. The roof seam, a-pillar wiring, interior rust staining, and all affected components remain available for inspection. How was safety put at risk? the a-pillar contains the srs curtain airbag system, its wiring, and connectors that should never be exposed to moisture. Continuous water intrusion over many months can cause corrosion, increased resistance, short circuits, or damage to the airbag inflator/squib circuit, which may lead to unintended deployment or failure to deploy in a crash. Water reaching the dashboard controls and electrical switches could cause intermittent electrical faults or malfunction of driver controls. These issues present a significant safety risk because the vehicle’s airbag and electrical systems may not function as designed. Has the problem been reproduced or confirmed? yes. The Toyota dealer has repeatedly observed the active leak, interior rust streaks, and bubbling/corrosion along the roof seam. The water intrusion occurs every time it rains. Has the vehicle been inspected? yes. Toyota has inspected the truck multiple times, including by a field technical specialist. However, Toyota has been unable to provide complete documentation or photos from the fts inspection, and the underlying safety issue remains unresolved. No inspections have been done by police or insurance. Warning lamps or messages? no warning lamps appeared. The first symptom was water leaking into the cabin around March 2024, followed by rust streaking inside the a-pillar and exterior bubbling. The issue continues during rainfall.

Fuel gage will randomly reset itself to full when the tank quantity is less than full or fuel gage will not reset to full after the gas tank is filled. A manual reset of the computer is required to force the gage to reset to an accurate reading. Driver is at risk of running out of fuel due to the gage overstating the quantity of fuel remaining. Numerous reports of this situation are found on youtube along with instructions on how to manually reset the software to force the gage to reset. Gage has malfunctioned 4 times in less than two months. Dealer could not find an issue with the system and requires the vehicle to be brought in during the malfunction. Issue started around 8000 miles and 22 months after initial delivery to owner.

On February 25, 2025, I took my 2023 Toyota Tundra VIN# [xxx] to stokes Toyota beaufort, SC, for its 45,000-mile service. Just 300 meters after leaving the dealership, my truck caught fire, causing significant damage and putting my safety at risk. I am sharing pictures of the incident and the warning messages I received on the dashboard. I was on my way back to the dealership when this happened. At first, the truck was shaking and losing power. I managed to make a u-turn to return to the dealership, but then the engine stalled. At that moment, I started seeing warning messages on the dashboard. I immediately called the dealership to inform them that I was experiencing issues with my truck. While still on the phone with the dealership, I noticed smoke coming from the passenger side of the hood. Moments later, flames started emerging from the hood. I quickly hung up and called 911. 1- what component or system failed or malfunctioned? I believe the engine and possibly the brakes failed (based on the dashboard warning messages). 2- how was your safety or the safety of others put at risk? within minutes, my truck burned completely. I am grateful I didn't have my children with me at the time. 3- has the problem been reproduced or confirmed by a dealer or independent service center? I received formal letters from Toyota manufacturer, Toyota distributor, and the dealership, stating that they are sorry for what happened but cannot offer any assistance with my claim. 4- has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? yes, the insurance company, fire marshal, dealership, Toyota, and engineering analysis associates (eaa) have all inspected the vehicle. 5- were there any warning lamps, messages, or other symptoms of the problem prior to the failure? yes, the truck was shaking, losing power, and eventually stopped completely, displaying warning messages on the dashboard. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C.

The fuel gauge displays full tank even though the tank is quarter empty. The local Toyota dealership is unable to resolve this issue. The fuel gauge malfunction happens almost twice a month now.

See attached document for complaint.

From the start, I would say after a few months of having my vehicle I had ebs issues and after that I had my vehicle shut down while I was driving and go into limp mode at it said engine reduce power or reduce engine power and it has done that four times this last time it said reduce engine power and all mercy breaking systems failed. There was a knocking in the engine, like there was no oil in it and all collision malfunction sensors breaking systems everything malfunction and vehicle shut off and engine was rattling took to Toyota and they told me that it was a manufacturing issue, but there was no recall my vehicle never even said I was low on oil even though I just had an oil change. It never gave me any alerts. It would just randomly lose power to the engine and shut down but this last time it was really bad.

Headlights go out randomly usually when using turn signal. Because this happens at night all visibility is lost temporarily. This also confuses other drivers. I haven’t taken the vehicle to the dealer because the symptom is very sporadic and difficult to duplicate. Dealerships will not fix anything unless they can witness the issue. No warning lights or messages were displayed. This problem has been documented numerous times by many different owners on Toyota Tundra forums.

Driving down the highway at about 75-80 mph and my passenger side mirror camera flys off lost to the highway.

This is my 4th time filling out this form. Fuel gauge and miles to empty will reset with the fuel gauge reading full and the miles to empty recalculating without putting fuel in the vehicle. My computer owners online account shows I have a fuel level of 153%. This truck has 2781 miles on it. The fuel gauge has reset itself 6 times in that mileage. Have now contacted Toyota customer fulfillment and now have a case number for the problem. My dealer then contacted me within an hour of getting that case number. Will now hopefully being getting closer to a solution.

The gauge fails to display the correct fuel level, especially when the fuel is below a certain threshold, which raises concerns about the accuracy of the reading and the overall safety of the vehicle. It will show full when really fuel is 1/2 tank.

Fuel gauge continues to reset to full with the miles to empty resting without putting gas in the truck. First reported to dealer and looked at on 7/12/24 with no solution. Second incident reported and truck left at dealer on 7/29/24. With no solution. 2 fuel gauge resets occured and reported to dealer on10/2/24 again with no solution except Toyota knows the problem but has no fixes. Last resetting of fuel gauge has occured on 10/9/24. I have been informed that other Toyota Tundra trucks have been into this dealership with the same problem of the fuel gauge resetting without putting any fuel in the truck. This vehicle should come with a reliable and working fuel gauge. This can become a hazard if running out of fuel. Dealership has now looked at this problem 3 times! 5 resets of the fuel gauge in 2315 miles.

Fuel gauge shows full after driving 120 miles.

The lens on the forward facing camera in the front grill cracked making the camera useless and in need of replacement. I first noticed the problem about a year ago. It is available for inspection. I can't see any damage around the camera that would have been caused by an object hitting the front of the truck which leads me to believe that the camera lens cracked because of a defect. The camera has not been inspected by the dealer however I have gotten a replacement estimate at the dealer.

Camera backup guidelines stopped displaying. Automatic mirror adjustment downward when shifting into reverse stopped working. Also unable to select different camera views.

All the cameras for parking and the driving lane assist failed while raining, the screen turned all green and started glitching, next day the truck was fine and this is the 3rd time, never got in an accident.

Fuel gauge will reset itself to full without filling the tank . Has happened on 3 occasions with only 1000 miles on vehicle. Have been to dealership but the explanation from Toyota is it happens due to elevation and direction in which the vehicle is parked. Problem has occurred for me twice when vehicle was parked on a flat surface after driving and once when parked on a slight incline after being parked overnight. Gauge does not return to normal after driving vehicle as it only moves down from full level. Toyota says situation may be due to location of fuel gauge sending unit in fuel tank. Dealership had vehicle for 3 days and replicated the situation. At this time I guess I will have to track road mileage to determine when to get gas and not rely on the fuel gauge. The dealership has been great, but has to rely on what solutions that corporate Toyota will supply them. Will continue to monitor the situation.

Fuel gauge randomly resets to full; true remaining fuel amount unknown unless vehicle is stopped and electronically reset. This is the second occurrence.

I have a 2022 Tundra that I purchased new. My current mileage is 18,500 and although my truck is part of the engine replacement recall that is not what I am complaining about, what I am complaining about is my front passenger window got stuck halfway open/closed and it's been sitting at the dealership for 2 weeks with no parts available to fix it (the cable snapped and motor burned out). They did put me in a rental (tacoma) but they have no idea when the parts will be available to fix my window! this is my 4th Tundra and never had an issue like this with any of my others. I've already called Toyota and they have no idea when parts will be available either. They also said they have no parts to fix the temporary fuel line recall which has been out for almost 1 year.

The tailgate opens on its own while I am traveling down the highway. I now have to brace anything I put in the bed of the truck lest the tailgate opens on the highway and I spill my load and cause a catastrophic injury or death on the highway. When shifting into park, having to keep my brakes firmly engaged due to a periodic and rapid acceleration of the engine. At cruising speed, on the highway, a vibration that only occurs when climbing hills coupled with a rapid pulsing of the engine/transmission. At cruising speed, on a level ground, the transmission rapidly disengages and reengages. Weekly I have gauge and infotainment malfunctions wherein I have to turn off the truck and restart it to make the gauges work. The gauges just freeze and fail to respond. The compass flips direction. Malfunctioning gas gauge. The backdoors lock and will not unlock. Occasionally, when they lock, I have to crawl into the backseat, from the from seat and manually unlock the door from the inside of the truck. A flat tire where when I went to change it, the jack bent…in my driveway. I now have to carry a 3rd-party jack and tools to handle emergency repairs. A regular malfunction of the rearview mirror. A cracked drivers seat. 6-months after purchasing the truck, the door trim came off in my hand. When I spoke to the Toyota tech, he advised me that this was not covered under warranty, and suggested that some customers keep the trim off as “most of the trim was installed with double-sided tape and would just fail again”. Though, to be fair, he did offer to, at several hundred dollars a pop, keep replacing the trim every couple of months. While my truck is parked in the garage, when the trucks system does an update, it opens my garage door.

Radio knob broke and radio audio became stuck at a loud status making it difficult to hear any first responder vehicles or concentrate/navigate through daily traffic. Please reference this thread for there are several Tundra owners dealing with this malfunction [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Fuel gauge automatically resets to full giving a false reading. Unknown fuel level creates travel hazard, because vehicle can shutdown during travel.

The digital instrument cluster continues to have freezing issues as well as blacking out while driving. From our previous experiences, this is more than likely due to software. There was a safety recall (23ta02) that was suppose to address some of these issues, but they continue to exist and happen. Not to mention that the fuel level will reset to full even though the vehicle has been driven for most, if not all, of the usable fuel. This continues to happen on 2024 model year vehicles.

Parking camera stopped showing backup lines. All other cameras suddenly stopped working.

This case results from the malfunctioning trailer brake ecu on 2018-2019 Tundras. There is a Toyota service bulletin t-sb-0036-19, which specifies an updated controller to replace the defective model. Part # : original 89547-0c020 update/replacement 89547-0c060 Toyota will not replace this defective part outside of the original warranty period despite the issuance of an updated replacement part. The service bulletin wasn’t even issued until 4/19 possibly giving no recourse to owners whose warranty had tolled. The newer part number, suggests this was a dangerous defect that was upgraded. A review of this matter online details this problem has frequently occurred. The reason it’s not more commonly reported is that a minority of Tundra owners tow trailers, and even fewer tow with electric brakes. Regardless, this is a significant safety issue where the Tundra owners are forced pay about $1,100 to repair this defective part. This matter should be elevated to a recall since losing the functionality of one’s trailer brakes is a very dangerous situation.

The transmission seems to be confused on which gear to select and hesitates to get the truck moving. It's happened to me at an intersection a few times and my car will inch forward but lags to accelerate, and vehicles behind me have been close to rear ending me. This is very reproducible in the mornings, it's very apparent or when the truck has been sitting off for a long period of time. After driving for a while it no longer happens. Every morning though this issue is apparent.

The digital instrument cluster continues to have freezing and lagging while in motion. The dte (distance to empty) has reset itself in the midst of driving with no input from the driver. This has continued to happen for multiple months. Also, the fuel gauge has become stuck. Toyota did release a TSB (t-sb-0022-23) to "resolve" this issue but it continues to be an issue well into the 2024 model year. See attached pictures.

1)over 60 mph with new tires the vehicle pulses & shakes on front end, checked alignment everything ok per mechanic.

Toyota has failed to deliver second key fob for vehicle operation. Purchased vehicle 5/4/24 and keep being told I will be notified in future about when 2nd key fob will be available. Cannot operate vehicle if fob lost and in area with no cell coverage. Dealership and corporate contacts have repeatedly changed the anticipated date of resolution, leaving no real sense of when issue will be resolved.

I am writing to bring to your attention a critical safety concern regarding the Toyota Tundra, specifically related to the rear tailgate functionality. It has come to my attention, and I have personally experienced, that the rear tailgate of the Toyota Tundra can unexpectedly open while the vehicle is in drive mode if the key fob is accidentally pressed. This poses a significant safety risk to not only the driver but also to any passengers and other drivers on the road. The unintended opening of the tailgate can lead to cargo falling out onto the road, causing accidents and potentially endangering lives. I believe that this issue warrants immediate attention and investigation by the national transportation safety authority (ntsa). It is imperative that Toyota addresses this issue promptly to prevent any potential accidents or injuries. I urge the ntsa to conduct a thorough investigation into this matter and work with Toyota to implement a solution that ensures the rear tailgate remains securely closed while the vehicle is in motion. Additionally, I recommend that Toyota issues a safety recall to rectify this potentially hazardous defect. Thank you for your attention to this matter. I trust that the ntsa will take appropriate action to address this safety concern and ensure the safety of all road users.

I did a software update when it pops up on my lcd screen. Then the screen turns black and multiple sensors came on. Lta sensor brake fail sensor crash senor and more. I look online and found out it has a apple car play issue that cause sensor to malfunction. I don't know if my truck is safe to drive. Afraid the airbag will blow up because of the crash sensor popping up and the failure brake senor also popping up. I took it took my local Toyota dealer sandia Toyota they didn't even look at it and made false accusations and try to charge me when my truck at 20000 miles. I took it to another dealer to get it fix. The incident started 4/6/2024 and today is 4/23/24 and I still have no truck to drive. I paid 70k for it but more concern for other. Please look into this issue making sure it safe for me and other.

I was driving on highway 98 at 76 miles an hour. A light came on the dash said engine is low on power. Then immediately the car said to get to the side of the road the engine had shut off. This was in the middle of a drive on the interstate. I almost got hit by a truck. With family in the car. I made an appointment at our local dealer for all the recalls and they canceled it last Friday due to their service force being sick. This almost got me and my son killed.
