2023 Toyota Tundra

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 that while reversing, the back-over prevention screen was inoperable, and there was no image displayed. The vehicle was taken to the local dealer, who determined that a software update was needed. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 25V657000 (BACK OVER PREVENTION). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 50,000.

The vehicle was taken to the dealer; however, no cause for the failure was found. The vehicle was not repaired. The contact stated that the failure persisted. The contact stated that the messages were displayed while on a long trip. The manufacturer was not notified of the failure. The failure mileage was approximately 53,000.

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.

We recently had an engine failure in our 2023 Toyota Tundra ([XXX]). Then on [XXX] the truck caught fire while we were driving in Arkansas. The fire caused the brakes to fail completely, and we wound up jumping from the still moving truck. The truck and contents were a total loss. Since then, Toyota has completed their investigation and stated they are unable to determine the cause of the fire INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When slowing down and then accelerating OR coming to a stop on an incline and then gassing it, the truck will stall for 1-2 seconds and then launch off. This has almost caused a wreck multiple times as I get stuck in the roadway for 1-2 seconds before being able to cross the lane and complete my turn. The dealership has said they've heard of the issue but could not duplicate it. No dashboard lights came on during the power failure.

The contact owns a 2023 Toyota Tundra. The contact stated that upon depressing the accelerator pedal while at complete stop at a red traffic light or while driving at various speeds, the vehicle hesitated to accelerate as intended. No warning light was illuminated. The vehicle was taken to a local dealer, where the transmission software was reset; however, the failure reoccurred. The vehicle was not repaired. The contact stated that the vehicle was previously taken to another local dealer, where an unknown engine recall was performed. The manufacturer was made aware of the failure. The failure mileage was approximately 40,000.
