2023 Toyota Tundra

I experience delayed throttle response and throttle lag daily. Acceleration is unpredictable. The vehicle barely moves in some cases when pressing the gas pedal. Other times, the tires will chirp. The vehicle will sometimes hesitate so long to accelerate, that I've almost been T-boned and I've held up traffic. It seems like the truck thinks I'm going to run into something, even when there's nothing in front of me. The delay is sometimes 3-5 seconds before it will allow any acceleration. This seems like a huge safety issue, not being able to get out of the way of oncoming traffic and having such an unpredictable, and often delayed throttle response.

Over the course of ownership I have had frequent instances of loss of power and/or lack of acceleration resulting in almost stalling out while trying to take off. This causes dangerous situations when trying to pull out into traffic because you never know when the vehicle might hesitate and crest unsafe distances between you and other moving vehicles.

The truck will hesitate for a brief second while trying to accelerate from both stop and in drive where it'll jolt you forward. This will also happen when shifting into driving and it jolts you forward. This is a huge safety risk because my truck can stall when i need the truck to go. I have brought it up to the dealership which told me multiple times as "normal". No lights has popped up but I know my other cars doesn't stall when giving gas.

My 2023 Toyota Tundra has an intermittent issue where the throttle lags or hesitates when accelerating from a complete stop. The problem occurs unpredictably and causes the truck to fail to respond when pressing the gas pedal. The issue appears to be related to the engine or throttle response system, and the vehicle is available for inspection upon request. This malfunction puts my safety and the safety of others at risk because the hesitation can occur while turning left across traffic or merging into traffic, leaving the truck momentarily stalled in the path of oncoming vehicles. The problem has not yet been officially reproduced or confirmed by a dealer or service center, but it has happened multiple times under normal driving conditions. The vehicle has not been inspected by the manufacturer, police, or insurance representatives at this time. There were no warning lights, messages, or other indicators before or during the hesitation; it happens without any prior notice.

I was driving my 2023 Toyota Tundra when the engine shutdown while going 55mph, the speed limit. Truck shutdown as I approached a long, curvy hill, felt like I was in great danger and any vehicles around me. There was no warning, had no idea what was going on. Took vehicle to dealership, after 24 hours I went back to dealership to check on it. Was told they didn’t look at it because they knew the engine was bad, needed replaced. There is a recall for this and was told there is no remedy yet. Also, they say they don’t have a vehicle for me to drive. I paid $65000 cash to have a vehicle to drive and keep me and my grandkids safe, now nothing!

October 6th 2025, I was leaving my place of work and started to here a slight banging/knocking sound, the vehicle lost instant power and I the engine quit running, I have taken the vehicle to the Toyota dealer and they have confirmed a internal bearing failure in the engine. The vehicle is not part of the engine recall but appears to be the same issue. The Toyota dealership has agreed that it is still with in the warranty period after review of there regional representative and agreed to replace the engine short block and rebuild the remaining engine components. I towed it to the dealer October 6th and have been given a rough timeline for repairs to be performed roughly around December based on the availability of parts.

Just asking for an investigation. Same engines in vehicle year 2023 gas only models have been recalled for safety because the engine locks up while driving causing a this safety issue. My model year is 2023 and is a hybrid but has not been added to the recall. The hybrid should be included in the recall as well since it is the exact same engine. This is a dangerous situation for me and my family as well as others I am on the road with.

My 2023 Toyota Tundra experienced a complete engine failure at approximately 25,000 miles. The vehicle suddenly shut off while driving and had to be towed to the dealer, where technicians determined that the engine had seized due to a spun bearing and a broken connecting rod. Toyota replaced the short block under warranty. While I appreciate that Toyota covered the repair, I believe this failure is directly related to the same manufacturing defect that led to Toyota’s ongoing Tundra engine recall. However, my VIN was not included in that recall campaign. Based on the nature of the failure, timing, and identical symptoms reported by many other Tundra owners, it appears Toyota’s recall does not fully capture all affected engines. In my case, the dealership documented that the piston connecting rod broke apart and that the main bearing spun—issues consistent with the debris and machining defects referenced in Toyota’s recall. Rather than performing a complete engine replacement (as done for covered VINs), Toyota only replaced the short block assembly, leaving other components potentially contaminated or compromised. This situation raises a broader safety concern: engine seizure at highway speeds poses a sudden loss-of-power risk that could lead to accidents. I urge NHTSA to investigate whether Toyota’s current recall scope is too narrow and to determine if additional Tundra engines—including mine—should be included.
