Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Global Techstream+ (GTS+) ECU flash reprogramming procedures and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard+ (CUW+). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU will initialize the flash reprogramming sequence.

Owners of 2023 Toyota Tundra trucks report multiple engine failure modes, many tied to NHTSA recalls 24V381000 and 25V767000. The most severe are sudden engine shutdown at highway speeds (55–85 mph) with zero warning lights before loss of power, requiring emergency maneuvers across traffic lanes. Several owners describe loud knocking or clamoring sounds followed by immediate shutdown, with some reporting metal debris found in oil pans post-failure. Engine seizure with spun bearings and broken connecting rods occurs as early as 8,000 to 45,000 miles. Hybrid and non-hybrid models both experience these failures despite Toyota's distinction between the two. Owners report rough idling on cold start, hesitation on acceleration, and temporary power loss that clears after restart, complicating diagnosis since dealers often retrieve no fault codes. One vehicle caught fire under the hood minutes after dealer service. Catalytic converter failure appears at 66,000 miles on a two-year-old truck. Oil cooling line routing defects cause radiator damage and pinhole coolant leaks without warning lights. Most critical: Toyota has issued recalls but states repair parts are unavailable, with some owners told not to expect remedy availability until January 2026, leaving owners driving vehicles they know are defective. Dealers deny warranty engine replacements to owners outside recall lists, offering short-block rebuilds instead, and in one case refused to perform recall repair oil changes. One owner was explicitly told the engine "pretty much has to be dead" before Toyota will process a recall claim.

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…
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…
It's a documented issue but not catastrophic. 114 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
Across the 29 complaints that reported odometer mileage, most engine failures cluster between 21,498 and 43,000 miles, with the median around 34,000. A quarter of owners report trouble before 21,498; a quarter make it past 43,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
