2023 Toyota Tundra UNKNOWN OR OTHER

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!!!

This is now a safety risk because I carry my child in the car, and I’m scared that my engine will lose power while I’m driving according to the recall. This is so irresponsible of Toyota that they still don’t have a remedy and I have been waiting.

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 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.

Vehicle stuck in 4WD HI after switching it from 2WD. Would not go back into 2WD. Did all the preventative maintenance including driving in 4WD HI once a month. Dealer claims is a switch outside the powertrain that is getting stuck. Replacement part ordered and will arrive in 4-8 weeks. Dealership saying I’m outside my warranty and part/labor will not be covered. My safety was put at risk d/t not being able to make appropriate turns when driving while truck was stuck in 4WD. No warning lights indicated 4WD system was not working appropriately. Truck would continue to show 4WD no matter what drive system I tired to use. Truck had no issues with 4WD system prior to this incident.

THROTTLE LAG/HESITATION

Engine hesitation.

Often times when accelerating from a complete stop, there will be a hesitation before the truck moves. Almost like it is about to die, but then accelerates. It can be dangerous at times when I need to pull through traffic to the opposite lane. I can’t have it stall and then someone hit the vehicle.

While parked on May 8, 2025, the sunroof glass on my 2023 Toyota Tundra spontaneously shattered. Minutes earlier, I had moved the vehicle from my driveway to the street. I have home security video that shows the sunroof panel visibly flexing when I closed the driver’s door—suggesting internal stress. Later, when I opened the door again and got inside, the glass suddenly exploded, creating a loud noise and sending shards across the sunroof liner. The glass appeared to explode outward rather than inward, suggesting a possible pressure buildup. This vehicle had just received its 40,000-mile service, and the glass was intact and undamaged beforehand. There were no warning lights, impact marks, or objects that could cause damage near the truck at the time. The failure occurred under normal conditions—no driving, no people around. I consider this a serious safety risk: If this had occurred while driving or with passengers inside, it could have caused injury or distraction-related accidents. I have multiple videos from my home security system showing: 1. The sunroof flexing under door pressure 2. The moment the glass shatters The dealer (Bayside Toyota) is scheduled to inspect the vehicle. The failed sunroof is available for inspection upon request. I have also asked the dealership to file this incident as a safety incident related to the Toyota Tundra.

Dash camera will not function and has to shutdown when the warning goes off.

Hesitation from a stop. Truck has a delay when pressing on accelerator nearly causing a collision. This happens randomly.

Hello, Noticed the fuel gauge was reading full after retrieving boat after a day of fishing. Before launching the boat the gauge read 1/2. Filled up at the gas station with the needle on full and it took approximately 16 gallons. The Toyota dealer said they could find no problems and reset the gauge. Running out of gas could be a serious problem towing a boat. Thank you

My truck’s windows (all 4) have terrible seals (not tight to window) that are allowing water to enter door. Windows have a jerk motion when wet and lowering. Moisture is present inside the cab on windows. Rear windows are extremely loose and can be a potential safety issue (I have video). Risk can fall on rear passengers because of instability of windows. Repair tech stated in report that there was an issue with windows by reproducing same motions with new trucks on lot (I have video from Toyota tech). Just inspected by dealer. No warning lamps. I have been trying to resolve this with Toyota Corp. with no further details of solution. I have all correspondence.

Vehicle stereo volume does not mute when a text message is received and being read out loud.

The vehicle's climate control system does not function as the instructions in the owners manual states. I have had it looked at by the dealer 3 times, once with a field technician, and filed a complaint with Toyota directly, all of which have been fruitless. In short, the fan speed function does not increase the output from the fan when increasing the fan speed at its switch. You can hear the fan speed increase, but no additional air comes out of vents if the vehicle is near the set temperature. In other words, you are not able to manually control the fan/blower. This has been replicated by the dealer each time, including the field tech. The response I have received has been both "it's functioning as designed" by the dealer, and "it's a known issue" from the Toyota field rep. Nothing has been done to resolve it nor update the owner's manual to indicate this is how the system is supposed to function.

It has been over one year since NHTSA Recall Number23V566 was issued (10 August 2023) and the final remedy is still not available. Safety of vehicle owners (and families) must not be very high on Toyota's or NHTSA's priority list. NHTSA must make Toyota take immediate action to correct this fire hazard. Waiting one year for a remedy for this fire safety hazard is way too long.

I was traveling on a hwy with the highest posted speed limit in the U.S. Without any warning the entire engine stopped. Made it to shoulder and the info screen went haywire. Tried six separate times to restart vehicle. Restarted and made it to destination without further incident. The outcome of sudden engine loss could’ve been fatal to myself and other drivers that were near me at the time. Took vehicle to dealer and was told no codes were found at all.

Toyota's design of their dash mounted "infotainment" display screen software requires reentry of a 6 digit pin any time vehicle internet connectivity is lost. This interrupts the map routing display that appears on the display screen through sources such as Apple CarPlay. This Toyota software designed interruption of the route display represents a safety hazard in that it prompts the driver to take their eyes off the road to screw around with entering a 6 digit PIN code. Worse still, according to Toyota documentation, EVERY TIME vehicle internet connectivity is interrupted, this same prompt to enter a PIN is displayed. Apple CarPlay and I'm sure other map apps are not designed so poorly as to require the driver to reauthenticate their credentials upon loss of internet connectivity. I feel the design of Toyota's infotainment system software represents an unacceptable safety risk to American drivers.

The tailgate can be easily dislodged from hinge when lifting from the passenger side of tailgate leading to it coming out of the C Hinge and hurting individual not expecting the full weight of tailgate coming off. No injuries luckily happened at the time of incident other than minor cosmetic damage from where the tailgate hit. I have video recreating what happened to describe the incident better but lack of hinge protection could result in serious injury if this occurs again.

Unknown. No incident yet. Concerned driving far. Recalls been 4 month and no action yet. Would like a refund of my money or a replacement vehicle. Also my tailgate feel off my tire pressure system comes on and tires are fine vehicle is a lemon.

While trying to get ahead of traffic at on ramp to freeway power was reduced and check engine light was activated. Pulled over soon after. Turned truck off and sat for a few minutes then turned truck back on Check engine was gone and truck ran normal. This could have been an accident but thankfully I had space to move over and get out of the traffics way.

The payload sticker is in correct .I did the math using the gross combined weight minus the curb weight and it does not match. There is no added options either that would lesson the payload.went to Koch Toyota they understood the problem but stated they don't know what to do. Any information on what I can do next please let me kno

As I accelerate from a complete stop; i.e from a stop light red to green. I experienced a sudden loss in power and the car does not accelerate through the intersection. It is very dangerous because the vehicle behind me almost rear ended me due the sudden lag/no acceleration.
