2023 Toyota Tundra: check engine light

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.

Recall 25V‑767 (Toyota 25TB14) is open on my VIN with no remedy available. Full statement and sources attached. XXX 12 days after the recall was filed and before I had any notice, my check engine light was on at an oil change at Colonial Toyota, [XXX]. The tech showed me the dealer's video of it and the light was cleared. I reported rough running and hesitation pulling away, and fear of a stall in traffic. The only rental offered was a subcompact, which cannot replace my full-size truck or tow my trailer. I was told nothing could be done until Toyota released a fix. None of this is on the repair order. I stopped driving the truck; by mid-XXX it had 19,923 miles. I asked the dealer in writing on XXX for the video, the cleared-code record and their retention policy. No response. Toyota says the video was auto-deleted and that it found no codes, but produced no code report and no deletion record. Toyota met the federal safety agency about rising failures XXX my CT lemon law protection ended XXX; the recall was filed XXX. The first recall (24V‑381) replaced engines; this one uses inspection software, and is still not available for my truck. Six owners sued over this engine ([XXX] v. Toyota Motor North America, D. Vt. No.XXX. In XXX Toyota paid the federal safety agency $48.8 million in penalties, including for late defect reporting. Please review whether: the remedy is timely and adequate; dealers are clearing codes without recording them, keeping warnings out of recall data; owners get usable transportation; and Toyota reported this defect as promptly as required. I am also preparing a formal complaint to the United States Department of Justice. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On XXX my 2023 Toyota Tundra Limited’s check engine light came on and after consulting with my service center, Jones Toyota in Bel Air, MD, via phone I brought the truck into Jones to be assessed. Jones diagnosed the problem and determined a physical failure of the passenger-side turbocharger. The vehicle is currently disabled and located at Jones Toyota in Bel Air, MD, undergoing service for the turbo failure. My vehicle is also subject to active safety Recall Campaign 25TA14 for manufacturing debris in the V35A engine block, but the dealership and manufacturer are treating the turbo failure as a separate repair item and have not linked it to the recall in writing. Operating a twin-turbo V6 platform experiencing sudden propulsion and turbo loss—while an open, un-remedied main bearing engine recall remains pending on the same vehicle—presents a severe underlying safety and mechanical failure pattern putting anyone in the vehicle or on the road with the vehicle when its being operated at risk

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 driving the vehicle on a public roadway at approximately 70mph, the vehicle suffered a sudden and catastrophic powertrain failure without timely warning. The check engine light illuminated, the physical engine oil pressure gauge dropped to absolute zero, and the dashboard immediately flashed a critical "Hybrid System Malfunction" warning. > This mechanical and electrical failure triggered an instantaneous, total loss of motor power while traveling live lane with traffic behind me. The vehicle immediately stalled and became a completely inoperable, unresponsive rolling hazard. The vehicle failed to restart and left me stranded on a narrow shoulder which was very hazardous as traffic coming at high speeds could have easily rear ended me. The vehicle required a flatbed tow to an authorized Toyota dealership, and after submitting a case with corporate hoping for a trade assist(as my wife no longer feels safe in this chassis), I have been told it will take up to 45 days to process this request. I made a significant investment in this vehicle in January of 2023 and have since methodically kept up with maintenance, with hopes this vehicle would last me 10+ years. I find it highly inexcusable for Toyota to not consider speedily helping a loyal customer in this situation and making it right in a timely manner. I am now being offered a vehicle the same as mine of the current year and with me having to put over 22K in equity to close the gap. I should not be left on the hook for something that put my safety at risk and now has left me without the ability to travel as my family has lost their main method of transportation. Manufacturing defects should not come at the customers expense.

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.

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.

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 the federal safety agency 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.

While driving today the engine check light turned on, and the engine turned off (stalled) while in the middle of the road with a good amount of traffic around me. I pulled off to the side of the road and gave the engine a minute. I turned the truck back on again, the engine sounded very rough turning on and rough while driving. After a minute or two of driving, the engine light turned on again, and the engine stopped (stalled) again while in the middle of the road. I stopped this time for two minutes or so and turned the engine on again. I then proceeded to try to make it home, which I accomplished, but the truck's engine sounded rough and with a chattering sound (engine knocking) even when idling. I have received a recall notice letter concerning " Certain 2022-2024 Model Year Tundra Vehicles Engine May Stall During Driving." I possess the letter with the federal safety agency Recall Number and the Toyota Recall Number. In the letter, it mentions the condition for which it is being recalled. The conditions are as stated in the letter. "Machining debris may not have been cleared from the engine when it was produced. In the involved vehicles, this can lead to engine knocking, engine rough running, engine no start, and/or a loss of drive power. A loss of drive power while driving can increase the risk of a crash." My truck has experienced all of the disfunctions that are stated in the recall letter. I would like for Toyota to look into this and remedy this problem before it ends in a major fatal crash or any other unfortunate circumstance. Thank you!

While driving under normal conditions, my 2023 Toyota Tundra TRD Pro Hybrid experienced a sudden and severe loss of propulsion. The vehicle abruptly entered fail-safe (limp) mode and would not accelerate beyond approximately 5–10 mph. This occurred without warning and created an immediate safety hazard in traffic. Multiple warning messages illuminated simultaneously, including: Hybrid System Malfunction, Check Engine, Smart Stop System Malfunction, and Advanced Ultrasonic Detection Malfunction. The hybrid system effectively shut down and the vehicle could not maintain normal road speed. I brought the vehicle to a Toyota dealership. The dealership performed only ECM and hybrid ECU software updates and cleared codes. No mechanical inspection, oil pressure analysis, particulate inspection, turbo system evaluation, hybrid motor synchronization testing, or engineering-level diagnostics were performed. Toyota Corporate subsequently stated that the software update was the “final” resolution and declined further diagnostics. I was advised to return to the dealership if the issue reoccurs. This failure mode matches the documented loss-of-propulsion behavior described in Toyota’s V35A engine machining-defect recall (sudden power loss, limp mode, cascading system failures). Hybrid models are currently excluded despite using the same engine platform and exhibiting identical symptoms. Sudden loss of propulsion at road speed presents a serious crash risk. This appears to be a safety-related defect that is not being adequately investigated or remedied for hybrid models.
