Toyota Tundra knocking problems

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.

My 2026 Toyota Tundra TRD Pro developed a sudden, loud knocking noise from the engine at approximately 15,000 miles while I was driving. The engine began running very rough, the vehicle started shaking, and the engine was losing power as I pulled over. The knocking was most noticeable at low RPM and followed engine RPM. There were no warning lights or warning messages before the problem occurred. I was able to safely pull the vehicle off the road, but the sudden loss of engine power and severe shaking created a safety concern. If the failure had occurred in heavier traffic or at highway speed, the loss of propulsion could have created a significant risk to me, my passengers, and other motorists. I stopped driving the vehicle because I was concerned about a complete engine failure. The vehicle was taken to an authorized Toyota dealership and is currently available for inspection. The dealer has confirmed the abnormal engine noise, but as of the date of this complaint the engine has not yet been disassembled and the exact internal cause of the failure is UNKNOWN. The vehicle has approximately 15,000 miles and is covered by the manufacturer's warranty. I am filing this complaint because the engine problem occurred suddenly at very low mileage and resulted in severe shaking and loss of engine power while driving. I am concerned that this condition could result in a complete loss of propulsion. I will provide additional information when Toyota completes its diagnosis.

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?

This is a repeat engine failure on a vehicle that already received the manufacturer's recall remedy. On XXX, at 69,420 miles, the original engine was replaced under Toyota's recall for the V35A 3.4L twin-turbo V6 (manufacturing debris contaminating crankshaft bearings), at Capital Toyota in [XXX]. On XXX, at 109,367 miles — approximately 39,947 miles after the recall replacement engine was installed — the replacement engine failed catastrophically. We first heard knocking in the engine while the truck was idling. The vehicle lost the ability to be driven and had to be towed to Savannah Toyota in Savannah, GA, where it currently remains. This failure raises serious safety concerns because the same recall-related symptoms (knocking progressing to failure) can occur while driving at highway speed, creating a risk of sudden loss of power, stalling in traffic, and a crash. This indicates that Toyota's recall remedy (engine replacement) did not correct the underlying manufacturing defect. We have opened a case with Toyota's Brand Engagement Center (case/file number XXX) requesting a third engine replacement.
