2023 Toyota Tundra Engine

Extreme throttle hesitation, and lag at low speeds. Causes a safety risk when in traffic or starting to stop situations due to the delay between when the driver presses the throttle pedal and when the vehicle moves. Often times the vehicle lunges aggressively. It happens every time you drive it.

The contact owns a 2023 Toyota Tundra. The contact stated that when the vehicle was started, the vehicle was unresponsive while depressing the accelerator pedal. The vehicle revved but failed to respond properly. The vehicle gradually reached 45 MPH, and then the check engine and several other unknown warning lights illuminated before the vehicle started losing motive power. The vehicle was unable to exceed 35 MPH. The vehicle was driven to a local dealer, and the dealer determined at first that the failure was related to the transmission, but later informed the contact that the failure was related to NHTSA Campaign Number: 25V767000 (Engine and Engine Cooling). The contact was informed that the remedy was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not informed of the failure. The failure mileage was approximately 43,000.

The contact owns a 2023 Toyota Tundra. The contact stated that after performing an oil change, metal fragments were discovered in the engine oil. There were no warning lights illuminated. The vehicle was taken to a local dealer, and the dealer confirmed that there were no active recalls associated with the VIN for the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and a case was opened. The manufacturer referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 36,000.

This is an engine failure recall and after multiple conversations with my service advisor, I am being told that my "vehicle is not ready for the corrective action at this time". When I ask him what constitutes "being ready", he states that "the engine pretty must has to be dead". My reply, "In other words, I need to be stranded with an inoperable vehicle before Toyota is going to allow a claim submission?" His reply, "yep, that is pretty much it." So, I am driving a car over mountain passes every weekend, late at night, just waiting for it to die for a known recall, and Toyota is not taking any action. This car only has 37,700 miles on it and it not what I expected out of purchasing a new Toyota.

Driving down the highway at about 50 mph. Went to pass another vehicle and engine shut off. Thank goodness was able to pull to shoulder and get towed to dealer. Could have been a catastrophic situation.

Toyota has recalled vehicles (24V-381) with the exact same motor that I have, but my truck has not been recalled simply because it is a hybrid. Their reasoning is that the hybrid motor will allow you to still move if the internal combustion engine does not work. Many hybrid owners have stated when their motor died they could not move. Toyota needs to include ALL the motors in this recall, including the hybrid engines. This is a safety issue that needs to be addressed.

Throttle lag Happens 2-3 time a day in many instances due to the delay almost causing accidents

Throttle lagging issues and delayed acceleration.

Since Toyota has recalled these engines, they have failed to produce a solution. This engine was recalled due to a safety concern, but yet they have not replaced the engine, nor do they even have a timeline for when it might be replaced. We use our Tundra for long distance towing with a heavy trailer. This has created a situation that is very concerning and my wife and I no longer feel safe in a truck that an engine can just seize in seconds leaving us not only stranded, but potentially in the roadway. The engine just dies, there are no warnings. We have lost a substantial amount of money on this because now the value of our truck has declined, which is not the standard Toyota had promised. Toyota had told all of us that they fixed this problem back in Feb. 2023. My build was a June 2023 model. It should have been safe and been taken care of, but Toyota didn't fix the actual problem back then. Toyota has not stood behind the vehicle or helped out for financial losses.

I have a 2023 I-force max hybrid and I’m concerned about the non hybrid model engine shares the same engine characteristics and parts use for the I-force max hybrid engine. I want to be on record if I have an engine failure due to debris in Toyota engine manufacturing process for my vehicle.

The contact owns a 2023 Toyota Tundra. The contact stated that upon starting the vehicle, the contact noticed an abnormal and clamoring sound coming from the engine. There was no warning light illuminated. The contact later received notification of NHTSA Campaign Number: 25V767000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The local dealer was made aware of the failure and confirmed that the parts were not yet available. The contact was offered the option to leave the vehicle in the dealer's possession, and the contact was also offered a loaner vehicle. 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 failure mileage was approximately 9,000.

On December 23, 2025, while driving at highway speeds, I began to hear a loud knocking sound. The sounds increased and a "low oil pressure" warning appeared on the dash. I began to loose power and the knocking sounds increased. I was able to carefully get the truck off the highway and parked to be towed to a local dealership. The loss of power while on the highway put myself and my family at risk due to not being able to keep at speed with traffic, and the possibility of being stuck on the side of a highway if I was unable to make it to the next exit. The vehicle experienced the same symptoms prior to the engine seizing in July of 2025. At that time the vehicle was not included in a recall campaign, and a short block replacement, rather than a complete engine replacement, was completed by Toyota.

The hybrid version of the Toyota Tundra uses the same base V35A-derived engine architecture, block casting, bearing design, and oiling system as the recalled non-hybrid vehicles. Toyota has not demonstrated that hybrid engines were manufactured differently or are immune to the defect that prompted the recall. In towing conditions, an internal combustion engine failure creates an immediate safety hazard even if limited electric propulsion remains available. Electric-only operation provides severely reduced power, limited speed, and restricted torque, making highway merging, grade climbing, or maintaining safe traffic flow unsafe while towing. Retaining minimal electric motion does not equate to maintaining safe propulsion under load. Additionally, a catastrophic engine failure may introduce metal debris, oil pressure loss, or thermal imbalance that can compromise shared drivetrain and hybrid coupling components. The presence of an electric motor does not mitigate the underlying defect risk or the secondary damage potential. Toyota’s distinction between hybrid and non-hybrid vehicles appears to be regulatory and financial rather than engineering-based. The same defect risk exists regardless of the hybrid system. I request that NHTSA evaluate whether Toyota’s exclusion of hybrid vehicles is based on actual engineering differences or solely on regulatory interpretation.

My Toyota Tundra (2023) has a recall notice due to possible debris in the engine that is over a year and a half old. This still has not been repaired by the manufacturer. I can hear sounds like knocking coming from the engine and I am concerned that the vehicle could stall or stop while driving on the highway with my children and cause a severe crash. How do I get the vehicle engine replaced expeditiously? The Recall is 24V381.

The vehicle is affected by a manufacturer safety recall related to the engine. According to the recall, machining debris may not have been properly removed during engine production. This can lead to engine knocking, rough running, failure to start, loss of power, or the engine stalling while driving. The manufacturer has stated that the fix will require replacement of the engine assembly, but the remedy is not yet available. Because of this, the vehicle continues to be driven with a known engine defect and no repair timeline. The main safety concern is the risk of sudden loss of power or engine stall while driving, which could be dangerous, especially at highway speeds or in traffic. The vehicle has been inspected by a dealer, who confirmed that the recall applies but could not perform a repair, provide a timeline, or confirm that the vehicle is safe to drive while waiting for the remedy. No crash or injury has occurred so far. There have been no warning lights or specific failure events yet, but the concern is based on the acknowledged manufacturing defect and the possibility that the issue could occur without warning. The vehicle is still being driven because there is no available repair, no clear safety guidance from the manufacturer, and no alternative transportation or loaner vehicle provided. The concern remains that the vehicle could unexpectedly lose power or stall, putting the driver and others at risk.

The contact owns a 2023 Toyota Tundra. The contact stated while driving at an undisclosed speed, the vehicle briefly lost motive power. The contact stated that the failure became a regular occurrence. No warning lights were illuminated. The vehicle was not diagnosed or repaired by the dealer or an independent mechanic. Upon investigation, the contact related the failure to NHTSA Campaign Number: 24V381000 (Engine and Engine Cooling). The VIN was included in the recall, but the part to do the recall repair was not yet available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 31,000.

I was driving my 2023 Toyota Tundra when the engine shutdown while going 55mph, the speed limit. Truck shutdown as I approached a long, curvy hill, felt like I was in great danger and any vehicles around me. There was no warning, had no idea what was going on. Took vehicle to dealership, after 24 hours I went back to dealership to check on it. Was told they didn’t look at it because they knew the engine was bad, needed replaced. There is a recall for this and was told there is no remedy yet. Also, they say they don’t have a vehicle for me to drive. I paid $65000 cash to have a vehicle to drive and keep me and my grandkids safe, now nothing!

Approximately 10 minutes into an ordinary drive home from work, the engine abruptly began making extremely loud noise, as if metal or bricks were being thrown inside the engine. Within moments, the engine rapidly lost power and then completely shut down. At no time did any warning lights, engine lights, or malfunction indicators appear on the dashboard prior to or during the failure. This incident represents a serious safety hazard. This vehicle is my primary tow vehicle for transporting a horse trailer, and had this failure occurred while towing, I would have had no control, no engine power, and no ability to maintain speed, creating a high risk of a major collision or highway accident. The fact that the failure occurred with zero warning makes the danger even more significant. Toyota has confirmed that this engine failure falls under the active recall. Despite this, the mode of failure—sudden shutdown while driving without any alert—poses a severe and immediate safety risk to drivers, passengers, and the general public.

I want Toyota to expand their engine recalls to 2023+ models. The issue with their engine remains with 2023+ models and it is a huge safety risk to allow a 6000lb truck to run on highways with the risk of the engine turning off and potentially crashing.

2023 Toyota Tundra with 31,000 miles on it and the main bearings was knocking and engine about to cease, Toyota has a recall for this exact same thing on truck that where produced two months earlier so I am told they are replacing the hole engine but for mine Toyota only wants to just do a half block when that main bearings goes it will put metal shavings though out the engine that’s why they are replacing the hole engine why not my truck. Have bought 4 Toyota had a 07 Tundra from new put 320,000 miles on it not a lick of trouble and cost half the price. No warning lights came on. Thought engine was going to explode. Has only been serviced and inspected by Toyota dealership. My advice don’t buy a new tundra. So let the run around begin on trying to get it fixed and for how long.
