2023 TOYOTA TUNDRA Complaints

Panoramic sunroof on 2023 Toyota Tundra spontaneously exploded while driving. The glass exploded upwards shattering glass everywhere onto the sunroof shade cover and into the truck bed. If the shade wasn't closed, the shards of glass would have fallen into the cab into the drivers face while driving. This incident was due to a defect of some sort and NOT cause by any external factors or objects.

The contact owns a 2023 Toyota Tundra. The contact stated that after performing an oil change, metal fragments were discovered in the engine oil. There were no warning lights illuminated. The vehicle was taken to a local dealer, and the dealer confirmed that there were no active recalls associated with the VIN for the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and a case was opened. The manufacturer referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 36,000.

This is an engine failure recall and after multiple conversations with my service advisor, I am being told that my "vehicle is not ready for the corrective action at this time". When I ask him what constitutes "being ready", he states that "the engine pretty must has to be dead". My reply, "In other words, I need to be stranded with an inoperable vehicle before Toyota is going to allow a claim submission?" His reply, "yep, that is pretty much it." So, I am driving a car over mountain passes every weekend, late at night, just waiting for it to die for a known recall, and Toyota is not taking any action. This car only has 37,700 miles on it and it not what I expected out of purchasing a new Toyota.

The monitor loses connection and requires a pin to come back up. While driving, following map directions, this requires you to try and do this while driving. Very dangerous. Especially in heavy traffic at speed . Thank you.

While operating my 2023 Toyota Tundra TRD Pro under normal conditions, I started the vehicle and activated standard factory equipment including the seat heaters and window/mirror defrosters. Shortly thereafter, I noticed a slight acrid odor inside the vehicle, which quickly became more pronounced. I drove approximately 200 feet, and immediately returned to my driveway. Upon shutting the vehicle down, I observed smoke coming from the engine compartment. I opened the hood and confirmed smoke and signs of an electrical fire originating in the engine bay. I used a fire extinguisher to extinguish the fire and then disconnected the vehicle’s battery. No injuries occurred. The vehicle was not restarted and was subsequently towed to an authorized Toyota dealership for inspection. Visible damage is present in the engine compartment, including the main fuse/relay box and associated electrical components. The incident occurred without collision and during normal vehicle operation.

Had recalled engine replaced on 12/6/25. on 1/22/26 took vehicle into dealership with issues with vibration in engine and hesitation at certain speeds, tonight 2/5/26 engine completely lost power at 65 mph on highway, dashboard flashing with every error to be had for Toyota engine. No power, rolled into emergency lane. Put hazards on. Turned engine off. Waited and engine was re-started and made it home. Extremely dangerous situation!!!

1-2 second period of no throttle response from a rolling stop, then a sudden lurch of acceleration. This happens all the time with my family in the car and its really scary.

My reverse stopped working, it just shows a black screen when I switch to it. The rest of my entertainment console works, it's only when I put it in reverse that it goes black. I saw that there was a recall issued for 2024 and 2025 Toyota Tundras, but I believe that the 2023 should be included as well. It looks to be a common issue, as I saw 2023 Tundras with a higher trim package also had a recall for the backup camera.

Since Toyota has recalled these engines, they have failed to produce a solution. This engine was recalled due to a safety concern, but yet they have not replaced the engine, nor do they even have a timeline for when it might be replaced. We use our Tundra for long distance towing with a heavy trailer. This has created a situation that is very concerning and my wife and I no longer feel safe in a truck that an engine can just seize in seconds leaving us not only stranded, but potentially in the roadway. The engine just dies, there are no warnings. We have lost a substantial amount of money on this because now the value of our truck has declined, which is not the standard Toyota had promised. Toyota had told all of us that they fixed this problem back in Feb. 2023. My build was a June 2023 model. It should have been safe and been taken care of, but Toyota didn't fix the actual problem back then. Toyota has not stood behind the vehicle or helped out for financial losses.
