2024 Toyota Tundra Engine

My 2024 Toyota Tundra imax hybrid started off with a knocking sound. I took it into a certified Toyota dealership to have it inspected. I was then told that they had ordered a part it needed to fix the problem. After not hearing back and the knocking getting louder. I reached back out and took it back for further inspection. They then told me that it needed a system update. After running the update, a couple of times later after diving the Tundra, it had a power issue when pushing the gas to accelerate. I then reached out to Toyota once again and took it back to be serviced. They told me that they test drove my truck and had no issues with acceleration. So I went and picked it up. Just a couple days after receiving my truck back, I was at an intersection with the blinking turn signal and attempted to take off when the truck completely stalled out. I had two cars almost crash into me, but barely missed! I started the truck back and went directly home. I then told Toyota about the situation and they told me to bring it back in. It then stalled again when I was taking it to the dealership. Once I got it back to the dealership and told them what happened, they said they would look into it. After they had it the first few days I never heard anything back, so I called to see what was going on with my truck. They told me that they were waiting to hear back from corporate Toyota for further directions from TAS. My truck then sat there for a few weeks. I kept reaching out to see what was going on and all they kept telling me is that they were working on it, and that they test drove the truck, but couldn’t get it to stall. I had the Toyota app on my phone, showing the mileage, and the mileage had never moved. Letting me know that they hadn’t actually test drove it. So after all of this, they never did any work on my truck. I was now scared to drive it, and honestly didn’t want it back.

The contact owns a 2024 Toyota Tundra. The contact received notifications of NHTSA Campaign Numbers: 25V322000 (Exterior Lighting), 25V767000 (Engine and Engine Cooling), and 26V038000 (Back Over Prevention); however, the parts to do the recall repairs were not yet available. The contact stated that while driving approximately 10-15 MPH, the vehicle experienced reduced engine power. The contact stated that while driving from a complete stop in the middle of an intersection, the vehicle stalled, almost causing another vehicle to crash into the vehicle. The contact was unable to pull over to the side of the road. There was no warning light illuminated. The contact was able to restart the vehicle and resumed driving. The contact stated that the failure had occurred on several occasions. The vehicle was taken to the dealer, where it was diagnosed and determined that the engine had failed and needed to be replaced; however, the part to perform the recall repair for NHTSA Campaign Number: 25V767000 (Engine and Engine Cooling); and was not yet available. The vehicle was not repaired. The contact was unsure if the manufacturer had been contacted. The failure mileage was approximately 36,500.

I am writing to formally file a complaint regarding my 2024 Toyota Tundra, which I purchased approximately five months ago. On two separate occasions while driving, the vehicle unexpectedly lost power. The first incident occurred while I was driving on the highway, which was extremely concerning from a safety standpoint. The second incident happened after I came to a complete stop and attempted to make a turn; the vehicle did not respond and had no power. In both situations, the power returned on its own moments later. These incidents raise serious safety concerns, especially given that the vehicle is relatively new. I am requesting a thorough inspection of the vehicle to identify the cause of this issue and ensure that it is resolved permanently. I would also like this concern documented in the vehicle’s service history. Vehicle Information: VIN: [XXX] Please advise on the next steps to address this matter promptly. Thank you for your attention to this issue. I look forward to your response INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle hesitates and starts to lose power and stall while driving. Toyota will not take action even though a recall has been issued and a letter in hand.

While driving I noticed a slight knock, about 10 miles further down the road the dash said engine has stopped pull over. No check engine or other lights were illuminated before or after this. The truck had a terrible noise when I tried to restart it, but it would not turn back on

The contact owns a 2024 Toyota Tundra. The contact stated that while driving at an undisclosed speed, the low engine oil warning light illuminated. The vehicle independently switched to Hybrid. The vehicle was driven to the shoulder of the road, and the engine seized. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine had experienced oil starvation, causing the rod bearings and engine failure. The contact was informed that the engine needed to be rebuilt or replaced. The engine was being rebuilt but was not yet repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 44,186.

As I was drive home at 45 mph the vehicle started surging and then the engine started knocking. then I stopped the vehicle and called Toyota for a tow. The truck was towed to the local dealer (Sheehy Toyota) for inspection. upon inspection the motor has a bad knocking in the lower end of the engine. The truck is now in the shop getting the engine disassembled. believed to be a main bearing failure. The truck has 9,229 miles on it. light use and had the oil changed 500 miles prior by the dealer.

The contact received a recall on the 2024 Toyota Tundra; however, the contact did not own the vehicle. The contact received notification of NHTSA Campaign Number: 25V767000 (ENGINE AND ENGINE COOLING); and requested to be removed from the recall distribution list. The local dealer and manufacturer were contacted.

While at a four-way intersection, I went to press the throttle, and there was a very significant lag in acceleration, almost causing an accident.

I am reporting a latent manufacturing defect in my 2024 Toyota Tundra i-FORCE MAX (Hybrid). This vehicle is equipped with the V35A-FTS engine, which has been officially recalled in non-hybrid Tundra models (NHTSA Recall 25V767) due to internal machining debris that causes catastrophic engine failure. Current Situation: Although my vehicle has not yet experienced a total engine seizure, it contains the exact same engine architecture and manufacturing origin as the recalled units. I am filing this complaint because Toyota has excluded the Hybrid models from the safety recall, citing that the electric motor acts as a safety backup. Safety Concern: My safety and the safety of my passengers are at risk because this "safety backup" claim is unproven and potentially false. Data from other owners suggests that a catastrophic V35A engine failure triggers a system-wide "Hybrid System Malfunction," which can disable all motive power, power steering, and braking assist. Driving a vehicle with a known "ticking time bomb" defect—where the engine could seize at highway speeds—creates a high-risk environment for a high-speed collision. Request for Action: I am urging the NHTSA to investigate the i-FORCE MAX Hybrid models and compel Toyota to expand Recall 25V767 to include all V35A-equipped hybrid vehicles. The exclusion of the hybrid model is a bypass of safety protocols that leaves owners like myself driving a vehicle with a documented manufacturing flaw that the manufacturer has already admitted requires a full engine replacement in other configurations. Inspection: The vehicle is available for inspection; however, the defect is internal and was caused during the manufacturing process, making it invisible to standard dealer inspections until the point of failure.

On July 31, 2024, my vehicle lost power while driving on the freeway and I had to make an emergency stop. Luckily I was able to do so safely. I brought the vehicle to Toyota Dealership South Bay to report this issue. The dealership inspected the vehicle but stated that they were unable to diagnose or replicate the problem and returned the vehicle to me without repair. The issue persisted and/or reoccurred after that visit. On November 6, 2025, Toyota Motor Engineering & Manufacturing issued Safety Recall No. 25V767000 (NHTSA Campaign Number 25V767000), titled “Debris in Engine May Cause Stall.” According to the recall, debris from the manufacturing process may contaminate the engine and cause the main bearings to fail, which can result in an engine stall and loss of drive power. The recall applies to certain 2022–2024 Toyota Tundra vehicles equipped with the V35A engine and affects approximately 126,691 vehicles. The recall states that a loss of drive power increases the risk of a crash. The defect described in Recall No. 25V767000 appears to directly explain the issue I reported to Toyota Dealership South Bay on July 31, 2024, more than a year before the recall was issued. At the time of my service visit, no recall, safety warning, or remedy was disclosed to me, and the concern was not resolved. Toyota has indicated that the remedy for this recall is currently under development and that interim notification letters were mailed to owners on December 16, 2025, with a final remedy to follow. This condition presents a significant safety risk because an engine stall and sudden loss of drive power can occur without warning while the vehicle is in motion, increasing the risk of a crash.

The contact owns a 2024 Toyota Tundra. The contact received notification of NHTSA Campaign Number: 25V767000 (ENGINE AND ENGINE COOLING). The contact stated that the recall was received for a vehicle that was never purchased and never owned, and requested to be removed from the recall distribution list. The local dealer and manufacturer were notified of the error.

Vehicle lost power and wouldn’t speed up while I was on the freeway and nearly caused a wreck because I couldn’t get the vehicle up to the speed limit. I pulled over and after shutting the vehicle off for an extended amount of time I then restated my truck but still experienced a lag in the engine. I would press the gas pedal and it took a while for the engine to seemingly engage and take off. The dealer was notified and they stated “we know of the issue but there is no fix, no need to bring it in as we are aware of the issues”

Vehicle experienced a loss of power while driving on a busy freeway and an extreme lag between pressing the gas pedal and when the vehicle would start going again. Called the dealership and was told “that’s a know issue with no current fix” they wouldn’t even look at the vehicle because there is a recall on my engine for this exact problem and Toyota does not have a fix yet.

I am submitting a safety defect concern regarding Toyota’s V35A 3.4L twin-turbo V6 manufacturing defect involving machining debris contaminating crankshaft main bearings. Toyota initiated a safety recall in May 2024 for MY 2022–2023 Toyota Tundra and Lexus LX vehicles, citing debris left in the engine during manufacturing that can lead to bearing failure, engine failure, loss of motive power, and increased crash risk. In November 2025, Toyota expanded this recall to include MY 2022–2024 Toyota Tundra, MY 2022–2024 Lexus LX, and MY 2024 Lexus GX vehicles, citing the same defect mechanism. Despite this expansion, Toyota has excluded i-FORCE MAX hybrid vehicles from the recall population. My vehicle is a 2024 Toyota Tundra i-FORCE MAX, VIN [XXX] , build date 02/2024, with 3,667 miles. It uses the same V35A 3.4L twin-turbo engine architecture and manufacturing process implicated in the recall. The presence of a hybrid electric motor does not eliminate the underlying defect mechanism (engine-internal debris contamination) nor the risk of sudden engine failure, loss of power under load, or unsafe drivability conditions. Excluding hybrid vehicles appears inconsistent with the stated defect cause and may result in similarly affected vehicles not being inspected, remedied, or disclosed to owners. I respectfully request that NHTSA evaluate whether Toyota’s exclusion of i-FORCE MAX vehicles is technically justified given the defect mechanism described, and whether additional investigation or recall expansion is warranted. At this time, my vehicle has not exhibited failure symptoms; however, this is a latent manufacturing defect with potential safety consequences.

Intermittent throttle response issues or engine lag. When coming from a complete stop, the truck will sometimes move slightly once the throttle is applied, then lose all engine power momentarily before beginning to move again. This is a recurring issue.

Engine hesitates momentarily when pressing accelerator from a complete stop. 98% of the time.

After coming to a stop there is an acceleration hesitation that cause the truck to take a second or two to start going again. This is very dangerous when pulling out in traffic

Was driving with flow of traffic and the Engine lost power went to zero RPM check engine light came on. It’s a non hybrids motor. Wouldn’t turn over once pulled on side of road Check underneath engine bay for leaks of fluid nothing was leaking.

Throttle lag happens quite frequently. Transmission issues dumping into gear stalling at times delayed start. Dealer says it was normal.

My 2024 tundra with 33000 miles is part of the latest recall, I called the dealership and was told I got to wait ( wait for what a XXX accident to happen) until Toyota sends me a letter and then dealerships get the parts! My truck is ticking, and not even running rite and no parts to fix it? Does anybody know how dangerous this is? XXX I drive myself and family in a 70000 truck that can literally blow up and cause a severe deadly situation especially living in southern Maine, and instead of fixing it rite away I gotta wait months from the sound of it.. no letter, no parts, no loaner, just prayers that God is with us until this XXX is fixed.. sad thing people with a brain know how dangerous it but nobody offers XXX.

Hesitation and throttle lag when accelerating the vehicle from a slow speed.

Was driving at approx 35mph when engine started making clanking noise and truck shut off. Stalled on main road and barely made it into parking lot. Tried to started it again and did not start. Had truck towed to dealership where dealership assumed engine has ceased at 32k miles. No warning, messages, or symptoms.

Vehicle completely shut off on remote 2 lane country road while traveling. No warning lights were noted or noises observed before the engine failure. Truck power steering failed to operate at optimal due to the engine cutting off. Was hard to get vehicle off into the grass as there were no shoulders to pull off to. Vehicle behind me as coming up a hill when this occurred had to break as well. The vehicle was towed to a dealership and they have confirmed catastrophic engine damage, and found metal in oil pan. This same problem occurred with the 23 Toyota Tundra's as well. The vehicle is currently at Bruner Toyota in Brownwood, Texas and a Toyota technician has been brought in. The truck has 47,698 miles on it.

Vehicle hesitates/loses power on take of from a stop started happening about 2 months ago 3/1/2025. Which causes the care to stop at intersections making it a huge risk to the passengers and other cars. Then last week the car had a low oil light. Dropped vehicle off at dealer they found no leaks or issues and added oil to the car and said to drive for another 1k miles and bring it back.
