2024 Toyota Tundra

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 NHTSA 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.

While driving, the vehicle unexpectedly stalled and lost power. The vehicle was taken to an authorized dealership for diagnosis, where the same stalling condition was reproduced and confirmed during a dealer road test. The vehicle had to be towed back to the dealership, where the engine was found to be seized. The sudden loss of power while driving created a serious safety concern because the vehicle could become disabled without warning and lose motive power in traffic. The failure was confirmed by the authorized dealership, and the vehicle and engine were available for inspection during the repair process. There were no known warning lamps, diagnostic messages, or other clear advance warnings that would have allowed me to anticipate the engine failure before the vehicle stalled.

While driving my 2024 Toyota Tundra, the check engine light illuminated and the vehicle suddenly experienced reduced engine power. I safely pulled over, shut the engine off, and restarted it. After restarting, the vehicle appeared to operate normally, but a diagnostic scan showed DTC P0300 (Random/Multiple Cylinder Misfire). On July 20, 2026, I brought the vehicle to an authorized Toyota dealer for inspection. During the inspection, the dealer found significant metal shavings in the engine oil, indicating a possible internal engine failure. Based on these findings, the dealer instructed me not to drive the vehicle and retained it at the dealership because they considered it unsafe to operate. My vehicle is already included in Toyota’s engine recall related to engine manufacturing defects. However, despite the dealer confirming the presence of significant metal shavings and advising that the vehicle should not be driven, no repair or resolution has been provided. The dealer has been unable to provide an estimated repair timeline or when the vehicle will be returned to service. The vehicle is available for inspection. No crash or injuries occurred. Prior to the incident, there were no warning signs or abnormal symptoms. The check engine light and reduced engine power occurred suddenly while driving. The unexpected loss of engine power created a significant safety risk, particularly while driving at highway speeds or in traffic. I am also concerned that an apparent internal engine failure occurred with little or no warning. In addition, because the dealer has retained the vehicle and no rental or alternate transportation has been provided, I have been left without transportation while waiting for a resolution.

When returning home from vacation towing my travel trailer. A warning light came on that said pull over immediately you have lost all power. I pulled over immediately and definitely had lost power and was stuck on a mountain pass. I called for a tow which took 7 hours. I called Toyota during that time and they couldn't tow me home just to the nearest dealer. My family and I had to wait for 7 hours on a small turnout on the road it was very hot that day. I had my truck towed to my local Toyota dealer and they confirmed it was the engine with metal shavings in the oil pan. Towing costs were 1102.50 out of my pocket as Toyota would not cover.

I own a 2024 Toyota Tundra 1794 Edition with approximately 37,000 miles. On or about XXX, while driving, the vehicle displayed a “Check Engine” warning, “Reduced Engine Power” message, and the Pre-Collision System became disabled. The vehicle immediately became sluggish and lost power during acceleration. The loss of power created a safety concern because the truck was unable to accelerate normally when entering and crossing intersections. I did not feel safe continuing to drive the vehicle, especially while transporting my 9-year-old daughter. Due to the safety risk, I parked the vehicle and have not driven it since the warning first occurred. The warning lights remain active. The vehicle has not yet been inspected by a Toyota dealer because I do not believe it is safe to drive to the dealership. I am requesting dealer evaluation and towing assistance. The component that failed is currently unknown. The vehicle is displaying a check engine light and reduced engine power condition. The condition can be inspected and diagnosed by Toyota. No crash, injury, or property damage occurred because I immediately stopped using the vehicle once the safety concern became apparent. I am submitting this complaint because a sudden reduction in engine power while driving creates a significant traffic safety hazard.

5/4/26 Truck brough in for service, I raised concerns of hesitation from a rolling stop/complete stop. This hesitation had happened to me a dozen or so times since purchasing the truck new in August of 2024. I expressed to my service advisor that I experience a 2-3 second delay in acceleration with the truck simply not responding after I have pulled out in traffic from a rolling stop. My service advisor noted my concern and got with the service manager. The Service Manager took the time to ride along with me in hopes of duplicating the problem. We were not able to reproduce the hesitation. Inconclusive findings was my conclusion of that service. T-SB-0032-26 was issued two days later on 5/6/26 7/3/26 Truck Brought in for service, I shared with my service advisor that I discovered T-SB-0032-26 while reiterating my previous experiences. TSB was performed on the truck successfully according to my service conclusion report. 7/7/26 Hesitation almost caused an accident. As I was crossing two way traffic, the truck hesitated. Traffic in both directions had to apply their brakes to avoid hitting me. This 2-3 second hesitation in acceleration creates a very unsettling moment. This is the kind of hesitation that could easily result in my getting rear-ended or T-boned in traffic. Other cars have to react to my truck not responding and slow down. If this causes an accident, I want this noted. I sent this information to my service advisor, the truck is going back to Toyota tonight for them to look into the computers history and see if they can find anything showing the hesitation. I even noted the date and time to my service advisor. Very interested to see what they do next.

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).

This is the second time this has happened to my truck. I was driving on the freeway at about 30–40 mph when the truck suddenly shut off. It was very scary because I was in moving traffic. This time, several warning lights came on, but I didn’t have a chance to see what they were because I immediately started to panic. I had to bring the truck to a complete stop by applying the brakes and then shifting it into Park. Once I did that, I pressed the Start button, and the truck started back up. This incident has me very concerned because it’s now happened twice. I’m worried that if it happens again, I could be rear-ended and seriously injured. I believe this is a significant safety issue that needs to be investigated and repaired as soon as possible. This is the second time this has happened to my truck.

While driving my 2024 Toyota Tundra Hybrid, the engine suffered a catastrophic seizure at approximately 37,974 miles. The dealership retrieved substantial metal machining debris (swarf) from inside the engine, which had contaminated the #1 main bearing. This is the exact same manufacturing defect Toyota has publicly acknowledged in multiple safety recalls for 2024 Tundras. Service Manager Dan Moran at Toyota of Colorado Springs confirmed during a recorded call that his dealership has seen the identical debris-related engine failure in other hybrid Tundras. Despite this, Toyota excludes all hybrids from the recalls. Even with clear physical evidence matching the recalled defect, Toyota directed an in-house rebuild (using a new short block but many of my original contaminated components) instead of providing a full factory crate engine. I was never offered a choice in the remedy. This sudden engine failure created a serious safety hazard due to unexpected loss of power. The current repair does not fully eliminate the known root cause (manufacturing debris contamination). The vehicle was well within warranty at failure and remains so. The dealership has the debris and full repair records available for inspection. I have also submitted the debris photo, repair documents, and recorded call summaries to NCDS (Case #[XXX]) and the Colorado Attorney General’s office.
