My 2024 tundra with 55000 miles suddenly lost all power going down a major highway. The engine failed suddenly. Luckily I didn’t wreck. I paid out of pocket to have it towed to dealership where it has sat untouched for 9 days. The engine is included in the recall that they have.
While driving my 2024 Toyota Tundra, the check engine light illuminated and the vehicle suddenly experienced reduced engine power. I safely pulled over, shut the engine off, and restarted it. After restarting, the vehicle appeared to operate normally, but a diagnostic scan showed DTC P0300 (Random/Multiple Cylinder Misfire). On July 20, 2026, I brought the vehicle to an authorized Toyota dealer for inspection. During the inspection, the dealer found significant metal shavings in the engine oil, indicating a possible internal engine failure. Based on these findings, the dealer instructed me not to drive the vehicle and retained it at the dealership because they considered it unsafe to operate. My vehicle is already included in Toyota’s engine recall related to engine manufacturing defects. However, despite the dealer confirming the presence of significant metal shavings and advising that the vehicle should not be driven, no repair or resolution has been provided. The dealer has been unable to provide an estimated repair timeline or when the vehicle will be returned to service. The vehicle is available for inspection. No crash or injuries occurred. Prior to the incident, there were no warning signs or abnormal symptoms. The check engine light and reduced engine power occurred suddenly while driving. The unexpected loss of engine power created a significant safety risk, particularly while driving at highway speeds or in traffic. I am also concerned that an apparent internal engine failure occurred with little or no warning. In addition, because the dealer has retained the vehicle and no rental or alternate transportation has been provided, I have been left without transportation while waiting for a resolution.
When returning home from vacation towing my travel trailer. A warning light came on that said pull over immediately you have lost all power. I pulled over immediately and definitely had lost power and was stuck on a mountain pass. I called for a tow which took 7 hours. I called Toyota during that time and they couldn't tow me home just to the nearest dealer. My family and I had to wait for 7 hours on a small turnout on the road it was very hot that day. I had my truck towed to my local Toyota dealer and they confirmed it was the engine with metal shavings in the oil pan. Towing costs were 1102.50 out of my pocket as Toyota would not cover.
I own a 2024 Toyota Tundra 1794 Edition with approximately 37,000 miles. On or about XXX, while driving, the vehicle displayed a “Check Engine” warning, “Reduced Engine Power” message, and the Pre-Collision System became disabled. The vehicle immediately became sluggish and lost power during acceleration. The loss of power created a safety concern because the truck was unable to accelerate normally when entering and crossing intersections. I did not feel safe continuing to drive the vehicle, especially while transporting my 9-year-old daughter. Due to the safety risk, I parked the vehicle and have not driven it since the warning first occurred. The warning lights remain active. The vehicle has not yet been inspected by a Toyota dealer because I do not believe it is safe to drive to the dealership. I am requesting dealer evaluation and towing assistance. The component that failed is currently unknown. The vehicle is displaying a check engine light and reduced engine power condition. The condition can be inspected and diagnosed by Toyota. No crash, injury, or property damage occurred because I immediately stopped using the vehicle once the safety concern became apparent. I am submitting this complaint because a sudden reduction in engine power while driving creates a significant traffic safety hazard.
5/4/26 Truck brough in for service, I raised concerns of hesitation from a rolling stop/complete stop. This hesitation had happened to me a dozen or so times since purchasing the truck new in August of 2024. I expressed to my service advisor that I experience a 2-3 second delay in acceleration with the truck simply not responding after I have pulled out in traffic from a rolling stop. My service advisor noted my concern and got with the service manager. The Service Manager took the time to ride along with me in hopes of duplicating the problem. We were not able to reproduce the hesitation. Inconclusive findings was my conclusion of that service. T-SB-0032-26 was issued two days later on 5/6/26 7/3/26 Truck Brought in for service, I shared with my service advisor that I discovered T-SB-0032-26 while reiterating my previous experiences. TSB was performed on the truck successfully according to my service conclusion report. 7/7/26 Hesitation almost caused an accident. As I was crossing two way traffic, the truck hesitated. Traffic in both directions had to apply their brakes to avoid hitting me. This 2-3 second hesitation in acceleration creates a very unsettling moment. This is the kind of hesitation that could easily result in my getting rear-ended or T-boned in traffic. Other cars have to react to my truck not responding and slow down. If this causes an accident, I want this noted. I sent this information to my service advisor, the truck is going back to Toyota tonight for them to look into the computers history and see if they can find anything showing the hesitation. I even noted the date and time to my service advisor. Very interested to see what they do next.
The contact owns a 2024 Toyota Tundra. The contact received notification letters for NHTSA Campaign Numbers: 25V322000 (Exterior Lighting) and 25V767000 (Engine and Engine Cooling); however, the parts required to complete the recall repairs were not yet available. Additionally, the contact stated that while reversing, an abnormal popping sound emanated from the differential. No warning lights were illuminated. A local dealer was contacted, but the vehicle was not diagnosed or repaired; however, the dealer sent an email offering a vehicle buyback. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 4,300.
Engine shutdown while driving (was towing a travel trailer at the time) and after coasting to a stop the engine would not start. After 10 minutes the engine would start, but had loud knocking. My 2024 Tundra only had 31,726 miles and had to be towed to the dealership. Seems to be the known engine issues with the redesigned v6 engine. Tundra has been in the dealership for 4 weeks and was told it will require engine replacement, but do not know when the new engine will be shipped. While Toyota will perform the replacement free of charge, based on the hundreds of thousands of Tundra's being recalled for this very issue, I no longer trust this engine design (replaced or not).
This is the second time this has happened to my truck. I was driving on the freeway at about 30–40 mph when the truck suddenly shut off. It was very scary because I was in moving traffic. This time, several warning lights came on, but I didn’t have a chance to see what they were because I immediately started to panic. I had to bring the truck to a complete stop by applying the brakes and then shifting it into Park. Once I did that, I pressed the Start button, and the truck started back up. This incident has me very concerned because it’s now happened twice. I’m worried that if it happens again, I could be rear-ended and seriously injured. I believe this is a significant safety issue that needs to be investigated and repaired as soon as possible. This is the second time this has happened to my truck.

While driving my 2024 Toyota Tundra Hybrid, the engine suffered a catastrophic seizure at approximately 37,974 miles. The dealership retrieved substantial metal machining debris (swarf) from inside the engine, which had contaminated the #1 main bearing. This is the exact same manufacturing defect Toyota has publicly acknowledged in multiple safety recalls for 2024 Tundras. Service Manager Dan Moran at Toyota of Colorado Springs confirmed during a recorded call that his dealership has seen the identical debris-related engine failure in other hybrid Tundras. Despite this, Toyota excludes all hybrids from the recalls. Even with clear physical evidence matching the recalled defect, Toyota directed an in-house rebuild (using a new short block but many of my original contaminated components) instead of providing a full factory crate engine. I was never offered a choice in the remedy. This sudden engine failure created a serious safety hazard due to unexpected loss of power. The current repair does not fully eliminate the known root cause (manufacturing debris contamination). The vehicle was well within warranty at failure and remains so. The dealership has the debris and full repair records available for inspection. I have also submitted the debris photo, repair documents, and recorded call summaries to NCDS (Case #[XXX]) and the Colorado Attorney General’s office.

I took my 2024 Toyota Tundra to dealer on December 4, 2025 for scheduled maintenance. At that time I was informed by the service advisor that there were 2 recalls on my vehicle. (1) Engine replacement recall and (2) reverse lamp recall. I agreed to leave my vehicle for the recall repair(s) as I was told they would be completed in 4 to 6 weeks. Here I am, almost 7 months later, and neither Toyota Corporation or dealership know when a remedy for these recalls will become available. I call consistently to Corporate and dealer and get the same response from both “we’re very sorry for this inconvenience and appreciate your patience.”I’m a patient person but this is way beyond being an inconvenience and patience has run out. Making payments faithfully on a vehicle you don’t have is beyond absurd.
While traveling on US Highway 95 between Lewiston and Riggins, Idaho, a 2024 Toyota Tundra TRD Pro with approximately 18,000 miles experienced a sudden loss of engine power while descending a mountain grade with multiple curves. The driver reported hearing abnormal engine noises immediately before the loss of power. At the same time, the brake pedal became extremely hard to depress and the vehicle did not decelerate as expected, requiring substantially increased braking effort. The vehicle was carrying family members and was traveling on a winding downhill section of highway adjacent to steep terrain. Due to the loss of power and increased braking effort, the occupants feared the vehicle would be unable to stop safely. Fortunately, a roadside pullout area was available, and the driver was able to steer the vehicle into the pullout and bring it to a stop without a collision. The vehicle was towed to an authorized Toyota dealership for inspection. The dealership diagnosed the vehicle with a catastrophic engine failure requiring engine replacement. The failed engine remains in the possession of the dealership and should be available for inspection. Approximately five days before this incident, the vehicle had undergone routine maintenance, including an oil change and inspection at a Toyota dealership. The vehicle had also previously been presented for brake pulsation concerns and other drivability-related complaints. The vehicle was returned to service and represented as operating normally. No collision occurred and no physical injuries were reported; however, the incident created a significant safety risk because the loss of engine power occurred while descending a mountain highway and the driver experienced substantially increased braking effort while attempting to stop the vehicle.
Vehicle has two open Toyota safety recalls that have remained unresolved for over a year. NHTSA campaign 25V322 (manufacturer no. 25TB06) covers reverse lamp assembly corrosion. NHTSA campaign 25V767 (manufacturer no. 25TB14) covers a V35A engine manufacturing defect where leftover machining debris can damage the main bearing, leading to engine knocking, rough running, no-start, or loss of drive power while driving. No engine symptoms have occurred to date. However, the vehicle is used for rideshare and delivery work, meaning passengers and cargo are regularly on board while this known defect remains unremedied. The dealership stated it could not address the engine recall and directed me to Toyota corporate. Toyota corporate opened a case and confirmed no remedy is currently available for this recall. The vehicle has not been inspected by the dealer or manufacturer, as no repair or inspection procedure has yet been provided to perform one. No warning lamps or dashboard messages have been observed. Vehicle is available for inspection upon request. Concern: a known crash-risk engine defect (loss of drive power) has been acknowledged by the manufacturer for over a year with still no completed remedy, while the vehicle continues to be operated commercially with passengers.
I have only owned the truck since mid April of 2026. The truck has 12000 miles on it. I have only put 200 miles on the truck... 150 miles are driving to the dealership. Engine recall notification was sent out last week of May 2026. Still an open recall for reverse lights with no remedy. Took Tundra into dealer at the beginning of May 2026 to get two other "electronic/infotainment" system recalls repaired. I bought the truck used from a dealership. Had three open recalls (electronic x's 2 and reverse light). Got two of three fixed. A few weeks later I get the engine recall. Really Toyota... I took the truck to Maplewood Toyota on 5/28/26. There it sits waiting for repairs. I asked about getting out of the truck and my option was trade it in at KBB value ($45k-ish) I paid $57k and $3k for extended warranty for a total of $60k. I am not going to eat $15k on trading in the truck. Toyota should STOP selling vehicles with these engines NOW! These engines should not be on the road or being sold - PERIOD. Toyota still using the "debris" in engine from manufacturing in 2024 is criminal. We are talking about the debris issue in 2022, 2023, 2024 engines.... This is outright criminal. Shame on you Toyota. I am a Toyota buyer. I own a 2019 Corolla. My friends and family are also Toyota owners. This V35A engine is a complete failure and production should be stopped. I kick myself for not doing more research before buying the truck. I never would have purchased knowing the ongoing engine issues. Dumb me - I am buying a Toyota because I trust there is no reason to worry - boy was I wrong. Please hold Toyota accountable for this. Toyota should buy back every vehicle that has this engine if the owners want that option. Anyone with a 2022 - 2026 V35A engine - drive at your own and everyone else on the road - risk.
Vehicle surges sometimes and repeatedly from a stop, with delayed acceleration; very dangerous when merging or moving from a stopped position into a flow of traffic (such as turning right on red). Vehicle sometimes will not move at all under acceleration, as if it has no gas at all. Vehicle is under recall for both of these issues related to the engine, but "no remedy available." Latest incident of surging was less than a week ago. Happens 2-3 times a day on average. Vehicle will occasionally randomly run rough at stoplights / idle speed. I have contacted Toyota regarding a buyback and they stated they "could not offer a buyback because they have not had adequate chances to fix the problem." So they have told me they cannot fix the problem, but won't buy back the truck because they have not had a chance to fix the problem (that they cannot fix). They have since stonewalled me and no longer respond to communications.
Vehicle: 2024 Toyota Tundra Double Cab | VIN: [XXX] | Mileage: ~19,200 No crash or injury has occurred. This report concerns an unresolved safety defect. My Tundra intermittently fails to accelerate when the gas pedal is pressed from a slow roll (3-18 mph). The engine revs but the vehicle does not move for 1-2+ seconds before the driveline abruptly engages. This occurs at intersections and during low-speed traffic transitions. It is worse on cold starts. I have experienced sudden unintended deceleration while attempting to enter traffic. This vehicle is covered under Safety Recall 25TA14 / NHTSA 26V320 ("Engine May Stall During Driving"). The TSB remedy was applied at my dealer on June 11, 2026. The remedy did not resolve the condition. I have OBD-II logs proving the defect persists post-remedy. Using Torque Pro at 10 Hz, I captured 55 instrumented hesitation events on June 11 alone -- 18 on the drive to the dealer before the TSB, and 37 after leaving. The worst single measurement shows a 1.7-second delay between pedal input and throttle blade response. My full dataset spans 131 events across multiple drives. Highway driving is completely normal throughout; the defect is exclusively a low-speed tip-in condition. The dealer has been unable to duplicate the condition across five repair order presentations since February 2025. The vehicle spent 105 days in dealer possession with no repair performed. I am reporting this as a failure of the Recall 25TA14 remedy on this specific VIN. Full OBD-II logs, GPS data, timestamped event charts, and all service records are available on request.

The engine lost power and shut down at highway speeds which put myself and a passenger at risk for a crash. There were no warning lights or other symptoms before the engine shut down. After pulling the vehicle over to the side of the road, I attempted to restart the engine. The engine failed to turn over and start. The truck towed into a local dealership and is waiting inspection.
The contact owns a 2024 Toyota Tundra. The contact stated that while driving at 80-85 MPH on I-95, the vehicle was sputtering, and the contact was concerned that the vehicle would stall. No warning light was illuminated. The contact received recall notifications for NHTSA Campaign Numbers: 25V322000 (Exterior Lighting), 25V767000 (Engine and Engine Cooling), and 26V038000 (Back Over Prevention); however, no remedy was available. The vehicle was towed to the local dealer but was not diagnosed or repaired. The contact was provided a loaner vehicle. The Attorney General was contacted and referred the contact to the NHTSA Hotline. The contact was requesting a buyback. The manufacturer was contacted, and a case was filed. The failure mileage was approximately 5,979.
2024 Toyota Tundra experienced a serious safety event. While travelling on the highway at 60mph speeds in traffic when the truck suddenly blinked a loss of steering warning light then immediately blinked engine failure warning light. The truck lost power and the engine completely shut down in traffic going down a long, steep hill. I was able to reach the bottom and pull over but the truck would not restart. I had to have the truck towed to a Toyota dealership near my home.
I have a 2024 Hybrid Toyota Tundra Equipped with V35-A- FTS 3.4 L Twin- Turbo V6. This motor is the same engine as the non hybrid motors included in the recall. There was recently a defect information report sent out on May 20th 2026 from Toyota stating that there is an issue with the main #1 bearing and the newer motors are now being installed with upgraded new bearing indicating that all motors, hybrid or non hybrid prior to August of 2024 have this defect that could cause engine failure. The only reason this motor is not included in recall is Toyota saying that it not a safety issue because of the electrical motor is sufficient to get it off the road. I tow a boat and various trailers and feel like at highway speeds in traffic a failure of the main engine, with very limited assistance from electrical motor could cause a potential serious crash leading to serious injury or death. I am filing this to ask NHTSA to do the right thing and have Toyota to expand the recall and include the Hybrids as it will only be a matter of time before before something will happen.
Vehicle Information: 2024 Toyota Tundra 4x4, VIN: [XXX] livery: [XXX] Current Mileage: 24,147 Complaint Synopsis: My 2024 Toyota Tundra is subject to two active open safety recalls with no remedy available ("NO FIX YET" status per Toyota owner portal). 1. What component(s) or system failed or malfunctioned, and is it available for inspection upon request? Primary: Engine assembly (Recall 25TB14 / 25TA14) – machining debris left in the engine during manufacturing. This can cause engine knocking, rough running, no-start, and sudden loss of motive power. Secondary: Reverse lamp system (Recall 25TB06 / 25TA06) – moisture intrusion causing both reverse lamps to become inoperable. The vehicle remains available for immediate inspection at Clearwater Toyota or by Toyota representatives. 2. How was your safety or the safety of others put at risk? The engine defect creates a severe risk of sudden loss of motive power while driving at highway speeds, which can cause loss of vehicle control and increase the likelihood of a crash. The reverse lamp defect eliminates rear visibility and brake indication when backing up in low-light conditions, significantly increasing the risk of collisions with other vehicles or pedestrians. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The defects are formally admitted by Toyota through active NHTSA safety recalls. Clearwater Toyota has refused multiple requests for inspection and service documentation. No independent inspection has been performed due to Toyota’s refusal to schedule one. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Toyota has not conducted a physical inspection of my vehicle despite repeated requests. Clearwater Toyota provided a temporary loaner vehicle but has refused to inspect or document the recalled conditions. No police or insurance inspections have occur INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I am filing this complaint regarding an active safety recall on my 2024 Toyota Tundra involving manufacturing debris left in the V35A 3.4L twin-turbocharged V6 engine during production. This recall has been open for multiple years and spans over 250,000 vehicles across the 2022–2024 Tundra, Lexus LX 600, and 2024 Lexus GX 550. The manufacturing debris causes damage to the engine’s main bearings, resulting in engine knocking, rough running, failure to start, and sudden loss of motive power while driving at speed — a condition Toyota itself acknowledges increases the risk of a crash. Toyota deployed a remedy consisting of full engine replacement; however, Toyota has since acknowledged that the replacement engines are experiencing the same failures, meaning there is currently no confirmed, working fix. Despite this, Toyota continued selling new vehicles with this known defect. Remedy deadlines have been repeatedly promised and repeatedly missed, with the latest expected resolution pushed to July/August 2026 — a deadline that has already slipped multiple times. As an owner, I am left driving a vehicle that Toyota acknowledges is dangerous, with no confirmed timeline for a legitimate repair, and suffering significant financial harm due to the ongoing depreciation and diminished resale value caused directly by this unresolved defect.
I was driving on the freeway in my Toyota Tundra when it suddenly shut off completely. It was honestly terrifying because my first thought was getting rear-ended in traffic. After about 15 seconds, the truck randomly turned back on by itself, but the whole situation really shook me up. A vehicle that new shouldn’t be doing something that dangerous.
I have a 2024 Hybrid Toyota Tundra which shares the same engine that has undergone a NHTSA recall. I do not believe that the defect has been satisfactorily addressed to mitigate the risk of catastrophic engine failure in the V6 engine. I would like the recall to include the hybrid models as well for this well known and documented engine failure risk. I have not yet had any problems with the engine yet and am addressing the other separate recalls for this model. From a safety and liability perspective, I feel that Toyota has an obligation to provide the same warranty extension assurance and if needed, engine replacement as the gasoline only variant.
The contact owns a 2024 Toyota Tundra. The contact received notification of NHTSA Campaign Number: 25V322000 (Exterior Lighting) and 25V767000 (Engine and Engine Cooling) however, the part to do the recall repair was not yet available. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.
STOPPED AT A TRAFFIC LIGHT, WHEN IT CHANGED TO GREEN THE TRUCK WOULD NOT MOVE. DISPLAYED HYBRID SYSTEM STOPPED WORKING, SHIFT INTO PARK. WE WERE THE FIRST VEHICLE AT THE LIGHT IN A HIGH TRAFFIC AREA WITH NO SHOULDER. TRAFFIC TRYING TO MANOUVER AROUND OUR VEHICLE WERE AT RISK OF CAUSING AN ACCIDENT. PARAMEDICS ARRIVED TO TRY AND DIRECT TRAFFIC. THE TRUCK HAD TO BE TOWED TO THE DEALERSHIP AND THEY VERRIFIED THAT THE ENGINE SIEZED.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
