2024 Toyota Tundra Engine Problems

First engine has not failed yet, it will happen. It presents a safety defect potential stalling , engine failure, or worse. ... It is same engine as non-hybrids . build date December 2023. Cuurent milage 23k . Toyota excluded hybrids with no proof safely exit hwy under electric power. i avoid passing lane for this very reason. Hybrid cannot gain speed to get over to side of the road. with drastic loss of speed . even more dangerous if pulling trailer. sumitt November 6, 2025 DEFECT INFORMATION REPORT Toyota sent to Nhtsa . Section no 6 i find very interesting and disturbing. While Toyota voluntary did recall , the report indicated engine failure not from debris but main bearing failure defects. grenade waiting to happen. hybrid owners with false safety from Toyota that can get over is a very dangerous message. Same defect engine exact as ones under recall. They are currently being sued over this. NHTSA must take action to include same defect engine in the hybrids. also putting link to a video of a tear down where took nearly 3 years get a blown engine for teardown. I see why now. 2026 engine has fixed main bearings with more oil pathways. IF IT WAS EVER A DEBRIS ISSUE , TOYOTA WOULD HAVE NEVER FIXED DEFECT MAIN BEARINGS AND MORE OIL PATHWAYS. FIXWD 2026 ENGINE GOING INTO RECALL. November 6, 2025 DEFECT INFORMATION REPORT shows that main bearing failure. With that allowing Toyota to exclude same engine in hybrid will be failure of of NHTSA.

With only under 23000 miles, engine started clunking on way back home from a day trip. Took the truck to dealer and they said the engine tech will see on Monday, but almost 100% it’s the engine. They want to rebuild and not replace because my vin is not in the Toyota engine recall yet. Please help with this, I can’t be risking pulling my 9000 boat and the rebuild engine to crap on me on the hwy with kids and family in truck. Thank you

NHTSA 25V-767 indicates potential issue with manufacturing debris in the engine potentially resulting in engine failure. Recall Status indicates "remedy not yet available". It has been over 4 months (11/6/25 to 3/19/26) since this safety recall was filed. This has been an unreasonably long time and Toyota should be compelled to initiate the remedy immediately and provide a detailed explanation as to why it is failing to meet its own code of conduct with respect to product safety and the law.

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.

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.

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.

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)

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

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.

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.

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.

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.

When starting from a very slight rolling stop I sometimes get no throttle response at all. When this happens i end up applying more throttle and I still do not move. Then after a second or two the truck takes off like a rocket. This usually happens at an intersection with the steering wheel turned one way or the other. Not sure if this is an engine or transmission issue or both.

The contact owns a 2024 Toyota Tundra. The contact stated that while driving in inclement weather, the rearview camera became inoperable, and moisture was visible in the displayed image. The contact also stated that while driving at 50 MPH, the vehicle stalled. There was no warning light illuminated. The vehicle did not need to be restarted. The contact received notification of NHTSA Campaign Numbers: 25V322000 (Exterior Lighting) and 25V767000 (Engine and Engine Cooling); however, the parts to perform the recall repairs were not yet available. The vehicle was taken to the dealer, but was not diagnosed or repaired. The dealer confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The approximate failure mileage was 40,000.

Several situations where the throttle hesitates when entering traffic or trying to come to interstate speeds on merge ramps. 1-2 sec delay has caused potential close calls while merging, when plenty of room existed to merge at speed.
