2024 Toyota Tundra: engine knocking or ticking

Filed Oct 18, 2026 · Engine · IN

I am the original owner of a 2024 Toyota Tundra Limited Nightshade equipped with the 3.4L twin-turbo V6 engine, purchased brand-new from Kerry Toyota in Florence, Kentucky, in July 2024. The vehicle is titled and registered in Indiana. At approximately 33,000 miles, my truck experienced an unexpected engine shutdown while driving highway speeds. I brought it to an authorized Toyota dealership- Kerry Toyota, Florence Kentucky for inspection, but was informed that no issues were found after they had the truck for weeks. Now, at approximately 41,000 miles, my truck has experienced another engine shutdown while traveling approximately 50 mph. After sitting for about 10 minutes, the engine restarted slowly and began making a knocking noise. The truck is currently at a Toyota dealership- Kerry Toyota awaiting inspection. I am extremely concerned about the safety of this vehicle, particularly because I previously reported a similar shutdown and the underlying issue was not identified or resolved.

The contact owns a 2024 Toyota Tundra. The contact received notification of the federal safety agency Campaign Number: 26V320000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The contact stated that while driving or accelerating from a complete stop, the vehicle hesitated for 5–6 seconds before accelerating as intended, with a ticking sound coming from the engine. Additionally, the contact saw puddles of oil on the garage floor, and there was an abnormal burning oil odor coming from the vehicle. Several dealers and the manufacturer were notified of the failure by phone; however, a diagnostic test was denied, and the contact was advised to wait until parts for the recall repair were available to repair the vehicle. The failure mileage was approximately 9,000.

On XXX6, while driving on the highway at approximately 89 mph and 36,714 miles, the engine misfired and the vehicle began shaking. The check engine light started flashing and a "reduced power, visit dealer" message appeared, along with a loss of motive power. The vehicle was taken to an authorized dealer on XXX at 37,032 miles. The dealer's repair order documents stored diagnostic trouble codes for random misfires, and states that freeze frame data confirmed misfires on cylinders 3, 4 and 5 at 89 mph and 2700 rpm in direct injection mode. Despite this, the repair order was closed as "no issue found." No repair and no further diagnosis was performed. The dealer stated the condition could not be duplicated after driving the vehicle and idling it for about an hour. The vehicle is subject to an open safety recall for machining debris in the engine (the federal safety agency 25V767, manufacturer 25TB14), for which no remedy is available. The recall summary lists engine knocking, rough running, no-start and loss of motive power as symptoms, and instructs owners experiencing symptoms to contact their dealer. When contacted, the dealer stated the manufacturer is still developing a remedy and that the vehicle can either wait indefinitely or be picked up as is. The defect remains undiagnosed and unrepaired. The vehicle is available for inspection. The safety concern is a sudden loss of motive power at highway speed, which is the same risk identified in the manufacturer's own recall filing. No remedy has been made available more than ten months after the recall was filed.

* 2024 Toyota Tundra Limited non hybrid TRD Off Road with 43k miles with catastrophic engine failure with no warning. Started as a very slight ticking sound while doing about 60 mph level to slightly downhill. * I could only hear it with very light throttle input (between 2 and 5%). Past 5% and at 0 pedal there was nothing. This went on for about 1 minute then it started to get significantly louder and more noticeable with throttle input and while starting to go uphill. * Shortly after it started catastrophically knocking with dash saying loss of power and oil pressure. * I get it stopped and it immediately shut down on its own. Due to very little warning I was forced to pull over on a right curve of a highway potentially putting my family and as well as passing traffic in danger. * Engine leaking oil. Couldn’t find anything obvious where the oil was coming from. After doing some research it seems like the front and main crank seals started leaking. More noticeable on the rear seal. This was a dangerous situation because oil was leaking on the hot exhaust and could have cased a fire on the side of a highway. * The Toyota dealer has possession of the vehicle for repairs. They have not stated if it is possible to be available for inspection. * The dealer has inspected the vehicle and is in the process of ordering a replacement engine.

engine knocks on start up or is very rough. the truck only has 8200 miles on it. i’m waiting for the recall to be processed but it’s been 2 years and i’m still waiting. i want to sell the truck because im afraid of it breaking down when i need it. but no one wants to buy the truck based on issues with the engines Toyota put in the trucks. how long do i have to wait for a new engine with the same design flaw? why is this issue taking so long to be rectified.How long do i have to wait for the back up light s issue to be resolved also? that’s also been 2 years! who’s sleeping at the wheel here to put pressure on Toyota?

Complete catastrophic engine failure at 36,514 miles on July 2, 2026, while the vehicle was being driven. There were no warning lamps, messages, knocking, or other symptoms prior to the failure - a sudden and total loss of motive power while the vehicle was in motion, creating a serious risk of a crash. The vehicle was towed to a franchised Toyota dealership (Hendrick Toyota Concord, Concord, NC), where the dealer confirmed the engine failure. The failure is consistent with the engine machining debris / #1 main bearing defect described in the federal safety agency Recall Nos. 24V‑381 and 25V‑767 and the related Toyota campaigns (25TB14/25TA14). As of this filing, the vehicle has been out of service at the dealership for more than 40 days with no replacement engine allocated and no repair date provided. A Toyota corporate case (#260805003088) is open. The vehicle and failed engine are available for inspection at the dealership.

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).

Vehicle has two open Toyota safety recalls that have remained unresolved for over a year. the federal safety agency campaign 25V322 (manufacturer no. 25TB06) covers reverse lamp assembly corrosion. the federal safety agency 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.

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 the federal safety agency 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.

While driving, I noticed that the vehicle seemed sluggish. Shortly after, I experienced grinding and knocking. The engine then stalled when I came to a traffic light. Fearing for my safety, I was able to get the engine to re-start to be able to pull off the road into a parking lot. At this point, the engine was barely running and making a ton of noise. There were no warning lights prior or after the incident took place. The vehicle was towed to my local Toyota Dealership who performed an inspection and determined that the Short block needs to be replaced, despite the contamination risk of other components. I have demanded that Toyota replace the engine with a complete new assembly, however, they are declining to do so.
