Electrical System Problems of Toyota Tundra - part 2

I bought the vehicle new in November 2025. 2026 Toyota tubdra trd sr5. In the first week I noticed a lot of jerking and shaking. I brought it to the dealer and was told it was a break in period and it should go away. I’ve had the truck in the shop 5-6 times since and the jerking and shaking hasn’t gone away. I’m at 6300 miles now. The dealer won’t even respond to me anymore. The only way to make the jerking go away is to step on the gas pedal harder but this has become extremely dangerous because it’s forcing me to go faster than I would like, especially in school zones. The dealers say that it’s the truck running very low rpm’s to maximize fuel efficiency and also because there are 10 gears but is that’s the case than why isn’t everyone experiencing it. It’s worse on cold mornings (40 or below) but it’s almost like the truck needs an hour or two to warm up. Even then it’s still jerking. My guess is that the truck doesn’t know what gear it’s supposed to be in but 4th or 5th gear are the worst where the truck hesitates and jerks. I’ve been told to run it in sport mode but that doesn’t help. I’m finding more and more complaints about this online with the Toyota Tundra sr5’s and I’m part of numerous groups. Someone needs to step in because no one should have to go through this and it’s very unsafe to have to push the gas pedal down harder to make the jerking go away. Thank you for your time.

Throttle lag/hesitstaion , from a dead stop at stop sign I attempted to accelerate , my truck went a few inches forward and no pedal response after a 3 second delay my vehicle started accelerating again.

There’s a delay in throttle response. Especially when making a turn across traffic. Throttle would not respond for at least 1 to 2 seconds. Even at full throttle the truck did not respond while cars were coming towards me. This has happened to several Tundra owners. Check facebook Tundra group and you’ll find others with same issue.

I’m writing to report a driver’s-door lock malfunction on my 2022 Toyota Tundra and to request goodwill assistance (reimbursement or no-charge repair). VIN: [xxx] mileage: 38,575 miles concern: the driver’s door does not lock/unlock using the key fob or interior switch. Manual locking still works. Other doors operate normally. Safety/security impact: the vehicle cannot be reliably secured and the condition may leave the vehicle vulnerable when parked. Troubleshooting performed: verified other doors work; checked fuses; inspected door-to-body wiring boot; issue appears isolated to the driver-side door lock actuator/latch. Requested resolution: goodwill coverage for diagnosis and repair (or reimbursement if I proceed with repair now), including parts and labor for the driver-door lock actuator/latch assembly. I’ve been satisfied with the vehicle and would appreciate Toyota’s help resolving this known-type issue just beyond the 3-year/36,000-mile basic warranty. Please open a case and advise next steps. I can provide service records, videos, and a dealer estimate upon request. Thank you for your assistance. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

2023 Toyota Tundra experienced repeated engine stalling and vehicle lock-up while driving on public roads, including in an intersection. During one incident, the driver was thrown forward into the steering wheel. A Toyota dealer attempted repair by replacing the neutral/park safety switch, but the repair failed and the dangerous condition persisted immediately after. The vehicle has been removed from use due to safety concerns. The issue is consistent with known engine stalling concerns affecting certain 2022–2024 Toyota Tundra vehicles. The vehicle is unsafe to operate.

I am the second owner of a 2024 Toyota Tundra that is branded as a manufacturer buyback/lemon. The first owner had the engine short block replaced at around 31,000 miles due to bearing failure. I later bought this truck at around 36,000 miles specifically because Toyota stated that the engine problem had been fixed with the short-block replacement. I relied on that representation and believed I was buying a vehicle whose defect had been properly remedied. Toyota has now issued safety recall 25v767 / 25ta14 (“engine may stall during driving”) for this same v35a engine, including service short blocks. I am concerned that the earlier short-block repair either did not fully fix the underlying defect or may have introduced additional problems. At around 41–42k miles, the truck developed starting issues and then completely failed to start, leaving me stranded in the middle of an intersection in town. The vehicle would not crank or start and had to be towed out of traffic, which I consider a serious safety risk. The dealer ultimately replaced a 50-amp fusible link, the 12v battery, and the starter. The total repair bill was about $2,100 before my third-party extended warranty paid a portion of it. Even with that coverage, this is an extremely expensive repair for a relatively new truck that has already had major engine work. Now I have engine history, electrical/starter problems, and I do not know what other issues may appear. I trusted Toyota’s assurance that the engine problem was fixed, and that is why I felt comfortable buying a branded lemon; this now feels like I was misled or cheated. I am also aware of ongoing engine and reliability complaints on newer 2024–2025 Tundras, which suggests there may be a broader design or quality issue. My concern is that my truck remains defective despite the prior engine short-block replacement and that other owners could experience similar no-start or stall situations in traffic.

The vehicle does not predictably respond to throttle inputs (if it responds at all), when you come off the brake pedal it will begin rolling at "idle" speed as normal but when you begin to increase throttle input nothing will happen for several very important seconds as you roll into an intersection or need the vehicle to accelerate to maneuver. This had happened multiple times before scheduling service appointments. The day before my appointment while trying to make a right hand turn from eb 13st st in lemont IL to sb bell rd, I had stopped for the red light, verified clearance to make the turn, and began my maneuver. Once I came off the brake pedal the vehicle began to roll into the intersection but as I began to turn the vehicle and try to accelerate though the turn it did not respond whatsoever. I desperately tried to roll my vehicle into the ditch to make space the incoming vehicles to minimize danger, but had no power to do so and was violently t-boned. The vehicle was brought to the dealer for their analysis, the service manager initially claimed "I know exactly what it is" and continued to ask questions that prompted previous knowledge of this issue including what speeds and conditions it will occur at. . Two weeks later the vehicle is "ready" and the manager claims the "eprom" had 2 pages of codes in it and that "got rid of the hesitation" I take him for a test drive with me and was able to recreate the issue a few times at which point he said "I understand your frustration with the truck but its a good truck" I drove the truck a few days and continued to experience dangerous and unpredictable delays in throttle response, one of which almost caused me to be rear-ended by a semi while merging from IL-rt83 onto I-55 nb the vehicle has been left behind on a family road trip as it is not safe enough for my family. In hind sight I wish I had the opportunity to submit it to NHTSA for examination after the crash rather than than Toyota. Please do something.

Huge delay in the throttle response. You press on the throttle and there is sometimes a hesitation and the vehicle will not move or is jerky.

The engine of my 2023 Toyota Tundra failed at approximately 34,500 miles. The failure involved sudden loss of oil pressure and severe internal damage, with metal shavings found in the oil and oil filter. The oil filter itself detached during the incident and was later recovered with metallic debris inside. The vehicle and the recovered filter are available for inspection upon request. While accelerating from a stop light on a busy morning public road, the engine suddenly lost power, illuminated multiple warning lamps, and entered limp mode with “low oil pressure” and “engine malfunction” messages. The truck rapidly leaked oil, creating a roadway hazard and putting me, my wife & son, and other drivers at risk of accident. I was able to limp the vehicle home . 5 miles from the incident at reduced speed, but complete engine seizure was a possibility. Toyota of fort walton beach inspected the vehicle, confirmed metal shavings in the oil pan, documented codes p05202 and p052049 (low oil pressure and oil pressure sensor stuck in range), and noted “oil was very metallic. ” the vehicle was inspected by Toyota dealership technicians and corporate representatives. I also have possession of the oil filter and photos/videos from the inspection. At the moment of failure, the dash displayed low oil pressure, check engine light, and a message regarding engine/electronic malfunction. Prior to this event, there were no warning signs — the truck had been serviced two weeks earlier at 33,360 miles, and I drove approximately 1,200 miles without incident until the catastrophic failure. This failure matches the description in Toyota recall 24v-381. My vehicle’s build date (February 27, 2023) is less than two weeks outside the published recall production window, yet the symptoms and inspection results are identical. I respectfully request NHTSA investigate whether additional 2023 Toyota Tundra vehicles outside the current recall window are affected, as my case demonstrates the same hazards.

Two issues happening at the same time. “key not detected” and “tpms system malfunction”. Key not detected: happens at various times, either at startup or while driving, an error message that says “key not detected “ comes on the dash and a loud beeping. My concern is that I may become stranded somewhere if the system cannot detect the key when trying to start the truck. The issue has been confirmed by both the dealer and Toyota and has not been fixed to date. Tpms system malfunction: at various times while driving, a warning message is displayed on the dashboard that states there is a malfunction with the tire pressure monitoring system and that it should be checked by the dealership. My concern is that the tpms system is unable to monitor the tire pressure and that could cause a dangerous situation. The issue has been confirmed by both the dealer and Toyota and has not been fixed to date. The truck has been back to the dealership 5 times for these issues and has been there for four days as of this writing.

The hvac climate control system in my 2025 Toyota Tundra limited malfunctioned while the vehicle was idling. The air conditioning had been set to cool and was operating normally, but without any touch to the controls or any alert, the system switched from blowing cold air to blowing warm/hot air. This caused the cabin temperature to increase rapidly. Because there were no warning lights, notifications, or error messages, there was no indication that the air system had changed. The vehicle continued to show that a/c was on and functioning. The malfunction resulted in the cabin reaching a dangerously high temperature. This caused fatal heat injury to one animal and critical heat injury to another, both of which were inside the vehicle at the time. One is still undergoing medical treatment. This same type of hvac issue has been reported by other 2024–2025 Toyota Tundra owners in multiple owner discussion groups, particularly related to the vehicle blowing warm air at idle or failing to maintain cabin temperature. This suggests a potential widespread defect, whether software-related or involving the a/c compressor control system. This presents a serious safety risk, especially for: children animals disabled or elderly passengers anyone unable to immediately exit the vehicle the vehicle remains in our possession and can be inspected. Service interactions with the Toyota dealership are documented and available. Immediate investigation is needed to determine the cause of this hvac failure and whether a recall or TSB must be issued to prevent future injury or death.

Fuel gauge won’t reset after filling the tank or it will stay on full after using the entire tank of gas. Running out of fuel on the freeway is a major safety issue!.

Both passenger seats by controls plastic cracking. Infotainment center blacks out and marker bars and back up lines for both back up and front parking have disappeared. Gps even when linked to my phone screen will black out but phone gps will still work. I have complained about this multiple times. Toyota did a factory reset on it and didn’t fix the issue took it back and a tech had to re-install program said the infotainment center has a known issue where it forgets the program. I also informed Toyota about the engine seems to be really sluggish when at a complete stop and then start again taking a few seconds to go along with shifting hard from stop and go. Toyota did say they saw what I saw and this usually happens when people double foot pedals. I told them I don’t do that. I am frustrated and don’t know what to do I have a 72k truck that just turned 17k miles on it with a lot of issues what will I have to deal with down the road once the warranty is up? I love Toyota but this time seems like I got a lemon from Toyota with all the issues and continued rising issues.

This owner's 2008 Toyota Tundra 5. 7l dashboard lights lit up including the vsc, traction control, check engine and 4 lo. The 4 lo light was flashing. The truck would no longer go past 3000 rpm on some occosians. Vehicle code reader identified this vehicle's secondary air injection system required repair and that this is a known defect with Toyota Tundras. Toyota issued an extended warranty to cover vehicles impacted by this defect, code p0418. This is a safety issue due to loss of power especially if random and unknown times when pulling into traffic normally would allow time to accelerate safetly but due to the sais malfunctioning it could accelerate slowly and cause a collision.

The tailgate will not go down when you push the bottom that is on the tail light or when you push the button inside the truck it will not go down. It makes the noise like if it is going to but gets stuck.

Intermittent message displaying "trailer brakes disconnected" while towing. Trailer lights continued to operate even while message was displayed. On average trailer connected and disconnected every 2-3 minutes.

The contact owns a 2025 Toyota Tundra. The contact stated that while the tailgate was closing automatically, her grandson's finger was at the upper closing point of the tailgate; however, the tailgate continued to close. The contact's husband put his body weight on the tailgate and was able to stop the tailgate from closing. There was no injury sustained. The vehicle was taken to the dealer, where the contact put her hand at the upper closing point of the tailgate while the tailgate was closing automatically, and the tailgate stopped closing as designed. The dealer informed the contact that they could not fix the tailgate failure to stop closing when a smaller hand or object was within the closing point. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 1,300.

The hood “open” sensor failed and indicated that my hood was not properly latched. The hood was latched properly. This resulted in a loud, distracting, and constant beeping that occurs anytime the vehicle is driven over 2 mph. This beeping has the potential to interfere with the driver and may result in an accident.

Keep getting the messages "trailer brake error, if towing come to a stop with manual controls" and "pre-collision system malfunction" the messages go away usually after restarting the vehicle but eventually comes back on.

Front active spoiler malfunction last week I took the vehicle into Toyota due to this malfunction message on the vehicle. The spoiler failed and remained in the down position, unknowingly causing additional damage to the spoiler flap. It was determined that the motor assembly was not working and needed to be replaced. The motor, flap and related assemblies were replaced under warranty by the dealership on 07/17/2025. Within 2 days, the spoiler was stuck in the down position again, this time without the malfunction message on the vehicle. With this being stuck in the down position, it can potentially cause more damage to the vehicle being in the down position and lead to debris in the roadway depending on the damage. Toyota manual states to avoid driving the vehicle at high speeds when this issue is present. However, owners with this issue would not know there is an issue if the vehicle is not presenting an error while functioning improperly. The vehicle is scheduled to be looked at again tomorrow 07/22/2025, at corwin Toyota of colorado springs.

The contact owned a 2024 Toyota Tundra. The contact stated while the vehicle was parked in front the detached garage, the vehicle caught on fire and the incident was caught on the neighbor's camera at 4:31 am. The neighbor then informed the contact of the incident. The contact noticed that the vehicle had caught on fire and the fire was mainly coming out of the gas pillar area. The contact stated that the entire vehicle had burned to the ground. The fire was extinguished by the fire department. A fire department report was filed. No police report was filed. There was no injury sustained. The vehicle remained at the scene and was in the process of being totaled by the insurance company. The dealer was notified of the failure and provided vehicle rental assistance. The manufacturer was notified of the failure and informed the contact that it would take up to 30 days for a field investigator to inspect the vehicle. Additionally, the contact was informed that it could take up to 45-60 days to determine whether there was liability. The failure mileage was approximately 13,900.

The truck has a hesitation or lag at stop signs every day, every stop sign it's like the transmission doesn't know what to do and doesn't shift into 1st unless you come to a complete stop for several seconds. Hit the throttle and nothing is happening. Even more scary thing that has happened about 8x so far is when you are stopped at an intersection and either need to wait for traffic to proceed across the road or if you are at a stop sign and waiting to merge into flowing traffic the truck will let you accelerate into traffic but then the throttle just goes dead. You can push the gas pedal all you want and the truck is just dead in the water for several seconds. Motor stays running and everything the throttle just wont work and you have to be very careful because when it suddenly comes back on if you have the pedal down to the floor it'll suddenly give you full power. It has almost caused me to get tboned 3x now and almost rear ended and then people are screaming at you and creating road rage because they think I just pulled out and stopped on purpose. I've gotten to the point I go to stop lights because I don't trust the truck to merge into flowing traffic. It feels to me like the crash avoidance is sensing something and cutting throttle but it doesn't beep or set off anything indicating that's what's happening. Dealer just always says they can not duplicate the issue. I'm going to mark 7/8/25 as the date that it's happend as I have that one written down but it did happen as recently as last week also I just don't remember the exact date.

I continue to get this message on my dash while driving and no one in front, on side or behind my vehicle: *foreign object speed acceleration reduced. *radio know broke a second time *windows stutter when going up or down while wet *windows rattle *poor acceleration at take off ( very dangerous on the expressway).

The contact's husband owns a 2022 Toyota Tundra. The contact stated that the key fob failed to unlock the front driver’s side door. Due to the failure, the contact was forced to lock the front driver’s side door manually after exiting the vehicle. The contact was forced to enter the vehicle through the front passenger’s side door and crawl over to the front driver side seat. The vehicle was taken to the dealer, and an estimate was provided for the repair. The vehicle was not repaired. The failure mileage was approximately 75,000.

Whenever it rains in dfw, vehicle emits a foul/musty odor from the hvac system. Only happens when it rains. Hvac setting has always been the same, "lo" temp, ac mode on, recirculation mode on, fan speed varies. Taken vehicle to two different dealerships and techs unable to duplicate. It doesnt rain much here in TX so it is hard to get it taken care of while still within warranty. My family and I use this vehicle primarily and I am concerned for my kids' lung health as they are [xxx], [xxx], and [xxx] years old as of writing. Running out of warranty time and hate to not get this fixed and be [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On may 20th, 2025 I was traveling in my 2022 trd pro Tundra 5. 5 hv. I was taking a left turn at a green light, when all of the sudden lights appeared on my dash saying “hybrid system malfunction, visit your dealer”. The car continued to function for approximately 1 minute, until the next light where it turned off. I tried to turn the vehicle back on, but it started to shake when it tried to start. At this point I was stuck at the light with traffic behind me, the engine had failed and the hybrid system had failed as well. I had to call 911 and request an officer to come assist, because I was blocking traffic. The vehicle had to pulled to a lot where I could unhook my boat that was in tow, and tow the truck to the beaver Toyota dealership. After arriving at the dealer and being there for over a week, I have been informed that they will be preforming a short block rebuild, because my truck is not listed in the 2022-2023 Toyota Tundra recall. Even though my truck experienced the same engine failure due to debris in the engine as all the 2022-2023 Tundras. My specific truck was not included in this recall because Toyota says the hybrid system would be able to move my car to a safe position if there was an engine failure. This was in fact not true because my hybrid system malfunction at the moment of the engine failure resulting in me stuck in the middle of the road blocking traffic having to call the police. Toyota needs to include trd pro hybrid owners in the 2022-2024 full block recall or face extensive legal action.

Reverse light not working properly unable to clear see while reversing.

The truck has a very pronounced hesitation to accelerate after slowing down or coming to a stop. Example: slow down, come to a stop at a stop sign and then accelerating to start moving. This situation happens daily and almost on every occasion after slowing or stopping. It has gotten worse over time and this issue has put me and my family in very dangerous and scary situations as the truck does not accelerate promptly and oncoming traffic is getting closer. It really has made me concerned to drive my truck and feel unsafe doing so, especially with my family.

The contact owns a 2024 Toyota Tundra. The contact stated that the rearview camera displayed a frozen image or a black screen while the vehicle was in reverse(r). The contact stated that the failure obstructed the driver's visibility, which prevented the driver from safely operating the vehicle. In addition, the infotainment screen failed to function as intended. While the contact was using the hands-free phone, the call occasionally disconnected. No warning lights were illuminated. The vehicle was taken to the dealer, where the contact was informed that the hands-free phone disconnecting was due to the cell phone service. The dealer updated the software. The contact stated that the failure persisted. The vehicle was taken back to the dealer; however, the vehicle was not inspected or diagnosed. The vehicle was not repaired. The contact stated that prior to the failure, the tires on the vehicle showed inner sidewall damage. The tires were not replaced. The manufacturer was notified of the failure. The manufacturer contacted the dealer, but no assistance was provided. The failure mileage was approximately 4,000.

I am experiencing a recurring issue with my 2024 Toyota Tundra’s fuel gauge. Specifically, when the vehicle is parked on an incline, the fuel gauge resets to indicate a full tank, regardless of the actual fuel level. For instance, after parking on a hill with approximately half a tank, the gauge displayed full upon restarting the vehicle.

I am the owner of a 2024 Toyota Tundra. My vehicle is subject to open NHTSA recall no. 25v-332, for which I received notification. It has now been over a year since this recall was issued, and no remedy has been made available to me. I have contacted my Toyota dealership and was told the remedy parts are not yet available' or 'no timeline could be provided. This unresolved recall leaves my vehicle in a condition that Toyota itself has identified as an unreasonable safety risk. The prolonged delay in providing a free remedy, as required under the national traffic and motor vehicle safety act, is my basis for this complaint. I am requesting that NHTSA investigate Toyota's compliance with recall remedy timelines and follow up on the status of parts/software availability for this recall.

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.
