2023 Toyota Tundra Engine

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.

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.

The engine misfired and failed twice in one year, and the vehicle is currently available for inspection. Both times the engine failed, I was on the freeway, which nearly caused cars and semi-trucks to rear-end me. I had a convoy of vehicles behind me and had to move to the right lane very cautiously. I reported the problem to the AutoNation Toyota dealership on Gulf Freeway. Yes, the dealership mechanics have inspected it, and it has been at the dealership since August 5, 2025. There were warning lights on the dashboard when the engine failed.

The engine seized up with 25,000 miles on it, on May 25th, 2025. I was not listed as under the engine recall, so they did a "Short Block" rebuild under warranty. I feel like this is insufficient and my vehicle should be under the recall for an entire new engine. My safety was put at risk because the vehicle shut down out of nowhere on a busy highway with narrow shoulders. I had to wait on the side of the road until a tow truck could get to me. Dealer confirmed it was seized up and ordered the short block replacement. No warning at all before the engine seized up.

I was driving down the [XXX] at 70 mph when suddenly the engine just went dead. There was no PRIOR warning as the orange engine symbol came on the dash at exactly the same time as the engine died. There were other warning symbols that came on the dash also at the same time. I then had to maneuver in heavy traffic without power steering or power brake at 70 mph to the side of the road which was very difficult and I felt very unsafe. It was frightening to say the least. I called the closest Toyota Dealership located in Bristol, Tn and they sent a tow truck to pick it up and take to their shop. I am now waiting for them to determine the extent of the damage. To be clear we have documentation of every required maintenance done. This truck is about 1 1/2 yrs old with only 68,000 miles on it!

While on vacation, approximately 400 miles from home, the engine dash light came on. The truck seem to be running fine but I did notice a different smell coming from the exhaust. I was able to return home and took it to the dealership as soon as possible. The dealership, Stephen Wade Toyota, contacted me and said that my driver side Cadillac converter had gone bad. They had no explanation of why it went out, but I would need a new one at $2,143.15. I asked if the Cadillac converter was covered under any type of warranty and the dealership informed me that in Utah it expired at 35,000 miles. Truck has 66,000 miles and regular maintenance has been performed on the vehicle. It seems extremely premature that a 2 year old vehicle with 65,000 miles would be experiencing a Cadillac converter failure.

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 Tundra has a build date of January, 2023. The Engine recall by Toyota included models up till February 13, 2023. I want to know specifically why my vehicle was not included in the recall even though it was built within the recall period.

I was driving on the highway at 55 mph when my engine suddenly began making a loud knocking noise and lost power. I immediately pulled over, but as I was doing so, the vehicle lost all power and the engine light came on. This was a dangerous situation because I was in the middle of traffic and almost got rear-ended as I couldn’t keep up with the traffic speed. Let alone the warning light didn’t come on until I lost all power to the engine. This is a 2023 Hybrid Limited with under 15,000 miles! I could not believe it as I just got rid of my 2022 Tundra Limited with engine issues and purposely got a hybrid to avoid engine problems. Toyota, what on earth are you doing?!

My vehicle has same engine as all the ones recalled, even built in same factory. Why isn’t there a recall on my engine as well.

Driving down the highway going about 80-85 mph and the engine just shuts offs. Get dash message to pull over engine has lost power. RPM gauge is at Zero (0). I eventually am able to pull over to the shoulder in which I shut the engine off. Tried to restart and engine wouldn't restart. After 5 min pass, I am able to start the truck back up and drive off. But now the confidence that my truck is safe to drive on the highway has been shot and I worry if I should even take it on the highway again. Took into local Toyota dealer to have it looked at and of course, service technician does not get any computer codes saying what happened. They could not duplicate the event, so they are putting me back in the truck with no explanation as to why it happened and if it will ever happen again. There was no true fix for this issue, just to bring it back it it happens again. The chances that if and when it does happen, there probably won't be a computer code again.
