2023 Toyota Tundra: sudden loss of power

Filed Oct 10, 2026 · Electrical, Engine · MS

2023 Toyota Tundra. On July 20, 2026 and again on September 18, 2026, while driving, the truck suddenly lost power and went into limp mode. The dash showed 'Check Engine / Reduced Engine Power / Visit Your Dealer' at about 43,440 miles. The truck had to be towed to the dealer on a flatbed. Losing power without warning in traffic is a serious safety risk. Other ongoing problems: the brakes squeaked for over a year before they were fixed, the driver seat bolster plastic is broken (this would be the third repair), the radio volume knob has failed, and there is excessive wind noise. This VIN still shows open recall 25V767 (engine machining debris causing loss of motive power), which has not been performed despite two dealer visits for this exact failure.

turbo's have to be replaced because of a wastegate failure. This is a well known issue. My vehicle is at 66700 miles and Toyota has denied a good will claim. Though they admit there is nothing I could have done differently because its a defective part. My safety is put at risk because the truck goes into limp mode and a "reduced power" message is displayed. The dealership has confirmed the issue but because its 7k outside of warranty they are unwilling to do anything even though its a defect. Vehicle has only been inspected by dealership. they also have a diagnostic test for the total engine recall and its very subjective. I don't believe they are keeping safety in mind. I think they are trying to deny as many of those claims as possible.

Ive been waiting for years for the previous recalls I have been informed about to get fixed. Feul system,brake lights.Was told by Toyota that someone would call me to come to get them taken care of. In the meantime, constantly checking that my brake lights are working before departing on any excursions in truck & patiently waiting for toyota to reach out when they were gonna fix the first 2 recalls that I was notified about. I can't recall the date exactly, but I was driving on the highway w/ my still backward carseat, facing 2y.o. baby safely strapped in,ThankGod.As accelerating into my lane, heard huge BOOM like an IED. Immediately, the check engine light among others came on.Truck immediately lost power & was violently shaking.Felt it in the steering wheel, but largely in engine compartment.@this time,I tried to get over to shoulder to a safe place.I turned the car off.Let it rest checked on my infant in back made sure he was ok. After letting car rest, turn back on to my surprise All lights were off.I was w/in few miles of home so went directly back, never getting to my intended destination. Shortly before driveway, all lights came back on & multiple service messages.Since then the truck has not been driveable,As we have specifically looked up recalls,thusly Nov.recall matched lights on the dash for the specific make,year, model of truck. From my understanding, it says that there is no remedy for such recall. But that is untrue. The remedy is an entirely new engine. They just haven't rolled out the recall info to everyone applicable. I am unable to work. My home is without a vehicle and this is unacceptable.Along w/ safety risk to me and infant. I'm sure Toyota doesn't want to admit or remedy Because that is very costly. But this was a mistake made by the company. And it should be remedied, because our family is suffering in various ways. Lost revenue. Inability to respond if emergency etc.I need a new engine.& in the interim,I need a car supplied while fixed.

While I was driving on Highway 459, the vehicle suddenly experienced a complete engine failure and lost power in the middle of the roadway. The vehicle could no longer accelerate or maintain its speed, leaving me stranded in an active traffic lane. This sudden failure placed me and other motorists at serious risk of a collision. Vehicles approaching from behind had to slow down, stop or change lanes to avoid hitting my disabled vehicle. I activated the hazard lights and attempted to move the vehicle to a safer location, but because the engine was no longer functioning, I was unable to safely remove it from the roadway. Before the incident, the vehicle displayed the following warning lights, messages or symptoms: NO PRIOR WARNING The vehicle was transported to OURISMAN TOYOTA OF WOODBRIDGE for inspection. The facility determined that ENGINE WAS BAD. The engine and vehicle remain available for inspection upon request. This was an abrupt and dangerous loss of engine power in active traffic. A vehicle should not experience a sudden engine failure that leaves it immobilized in the middle of a highway, especially without sufficient warning to allow the driver to reach a safe location. I am reporting this incident because the failure created a serious safety hazard for me and other motorists, and I am concerned that the same defect could affect other vehicles.

I am submitting this complaint regarding Toyota Motor Sales, U.S.A. and my 2023 Toyota Tundra, which is currently subject to Safety Recall 25V767 involving catastrophic engine failure risk due to crankshaft bearing contamination within the V35A engine. Toyota has acknowledged that my vehicle is included in the recall and has further acknowledged that the engine will require replacement. However, despite confirming the seriousness of the defect, Toyota has refused to repurchase the vehicle and has failed to provide any timeline whatsoever regarding when the engine replacement remedy will become available. Toyota’s position has simply been that the engine will be repaired “once a remedy is available,” without any estimated repair date or meaningful resolution for affected consumers. The recall itself states that the defect may result in engine knocking, rough running, engine no-start, and/or sudden engine stall. Toyota further acknowledges in its recall documentation that engine stall while driving can lead to loss of motive power and increase the risk of a crash. This is a major safety issue, not a minor inconvenience. I live and drive in [XXX] , where highway driving and high-speed traffic are unavoidable. Due to the risk of sudden engine failure or loss of power, my family and I no longer feel safe operating the vehicle under normal driving conditions. As a result, we have drastically limited use of the truck despite continuing to make monthly loan payments, insurance payments, and registration expenses. Additionally, the truck has experienced multiple other recall and repair-related issues since purchase. Several recalls have already required service visits, and additional unresolved recalls remain pending. The ongoing pattern of defects and unresolved safety concerns has substantially diminished my confidence in the reliability, safety, and value of the vehicle. Toyota acknowledges the engine requires replacement, Toyota provides no repair timeline INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION AC

Component/System Failure: The failure involves the engine cooling system, specifically the radiator, fan shroud, and oil cooling lines. The oil cooling lines are improperly routed or positioned, causing them to press against the plastic fan shroud. Over time, this pressure deforms the shroud inward, leading it to rub against the aluminum radiator and create pinhole leaks. The damaged components are available for inspection upon request. Safety Risk: This defect poses a serious safety risk due to sudden coolant loss and potential engine overheating. This can result in loss of power, engine failure, and unexpected breakdowns in traffic, increasing the risk of accidents, especially at highway speeds. Reproduction/Confirmation: This issue has been widely reported among 2023 Toyota Tundra owners and confirmed through visual inspection by owners and independent mechanics. The consistent nature of the failure indicates a design defect rather than isolated incidents. Inspection History: The vehicle has been inspected, and deformation of the fan shroud along with visible contact and wear on the radiator confirms the issue. Dealerships have acknowledged the condition but refused warranty repairs. Toyota has not issued a Technical Service Bulletin (TSB). Warning Signs/Symptoms: There are typically no warning lights or messages prior to failure. In some cases, coolant loss or overheating occurs only after radiator damage has already developed. Additional Statement: This is a widespread defect caused by improper routing or clearance of oil cooling lines. Despite numerous similar reports, Toyota has not issued a TSB or recall and has denied warranty coverage, leaving owners responsible for repairs related to an apparent design flaw.

While driving on a two-lane highway at approximately 80–85 mph and attempting to pass another vehicle, the engine suddenly shut off without warning. The vehicle lost all propulsion, and steering assist was significantly reduced, creating a dangerous situation and nearly resulting in a head-on collision with oncoming traffic. Warning lights including check engine and low power steering illuminated immediately after the stall. The vehicle would not restart for several minutes and was temporarily disabled in the roadway. The vehicle was later inspected by a dealership, which confirmed through diagnostic data that multiple engine stall events occurred at highway speeds. The inspection also identified system-wide electrical voltage drops and multiple communication faults between control modules. The dealership attributed the issue to a loose battery terminal; however, the diagnostic report indicates prior voltage irregularities and multiple affected systems, suggesting a broader failure condition. This incident is consistent with an active safety recall affecting this vehicle, which states that the engine may stall during driving. The failure has not been reproduced since the initial incident, but the vehicle has documented evidence of multiple stall events and remains a safety concern. The vehicle is available for inspection upon request. Due to the sudden loss of power at highway speed and the inability to safely control or accelerate the vehicle, this issue poses a serious risk to the driver and others on the road.

The vehicle is affected by a manufacturer safety recall # 25TB14 related to the engine. A loss of motive power while driving at higher speeds can increase the risk of a crash. Because of this I have stopped driving the vehicle. According to the recall, The manufacturer has stated that the fix will require replacement of the engine assembly, but the remedy is not yet available and no expected remedy or repair time is given. 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. The manufacturer acknowledged a manufacturing defect and the possibility that the issue could occur without warning. There is no clear safety guidance from the manufacturer, and no loaner vehicle provided. The concern also remains that the vehicle could unexpectedly lose power or stall, putting the driver and others at risk.

My Tundra has been having lagged throttle after takeoff for a few months now going into 2026. My truck is slightly over 50k Miles and did well for the first 40k Miles. Last week it went limp and gave a loss of Power Warning and Check engine light came on. Then the very next day a parking brake assist warning came on. I brought it to the dealer and after 4 days they couldn't replicate the warning light but seen that the Turbo had failure. They said they could not change the Turbo since theres an active Engine recall on my truck. My truck is sitting at the dealer with no committed date or fix for when my engine will be replaced. Not sure what to even do as im paying on a truck i cant even drive. Aside from this major issue ive had two window motors replaced and a non working hamstring leg rest motor. They instead offered to sell me a new 2026 which felt sleazy on their part. I will not be staying with my 2023 Tundra if and when i get it back knowing we only get a 1 year warranty and crate engines are already failing. Toyota is treating their faithful clients horribly on this issue they caused. Id go as far as saying this should be part of the Lemon Law act and more needs to be done.
