2023 Toyota Tundra Other Problems

Your panoramic sunroof suddenly shattered and exploded upward while you were driving, scattering glass onto the sunroof shade and into the truck bed. The closed shade prevented glass from falling into the cabin, but if it had been open, shards could have fallen into your face while driving. The manufacturer has indicated this was caused by a defect rather than any external impact or object. The sunroof glass will likely need to be completely replaced and the frame inspected for damage.

Your replacement engine, installed in December 2025, has developed serious problems. You've experienced engine vibration, hesitation at certain speeds, and most dangerously, a complete loss of power while driving 65 mph on the highway in February 2026—your dashboard flooded with error codes. After turning the engine off and restarting it, power returned, but this is a critical safety issue. The dealership will need to diagnose why the newly replaced engine is malfunctioning and likely replace or repair it.

Your engine may lose power while driving, which concerns you as a safety risk since you carry your child in the vehicle. You're waiting for Toyota to provide a fix for this recalled issue, and you're frustrated that no remedy is currently available.

Your 2023 Tundra is subject to NHTSA Recall 23V566 (issued August 10, 2023) for a fire hazard, but more than a year later, the repair fix still isn't available. You're waiting for Toyota to release and make available the final remedy to address this safety issue.

Your engine suddenly shut off without warning while driving at highway speeds, and your information screen displayed erratic behavior. You were able to restart the vehicle after six attempts and completed your trip without further issues, though the sudden loss of engine power created a dangerous situation. The dealer found no diagnostic error codes, which makes identifying the cause difficult and requires further investigation to determine if there's an underlying electrical or fuel system issue.

Your power windows on your 2023 Toyota Tundra are getting stuck halfway down and won't close, even when you push them up manually. This has happened on both the driver and passenger windows. The windows might trap your fingers, limbs, or objects unexpectedly, or fail to close during bad weather or when you need security. Your Toyota dealer has inspected and attempted repairs, but the problem has occurred again in a different window.

Your infotainment touchscreen monitor loses connection and requires you to enter a PIN to reconnect it while you're driving. This forces you to take your attention off the road to troubleshoot the system, which is especially dangerous in heavy traffic at high speeds. The issue may be resolved by updating the infotainment system software or checking the touchscreen's connection.

Your truck has a 1-2 second delay where the engine doesn't respond when you try to accelerate from a rolling stop, then suddenly lurches forward with a jolt. This happens repeatedly and feels unsafe, especially with passengers in the vehicle.

Your truck became stuck in 4WD HI mode and wouldn't switch back to 2WD, even though you performed regular maintenance including monthly 4WD drives. The dealer identified a stuck switch outside the transmission as the cause and ordered a replacement part (4-8 week wait). You're concerned because the truck display continued showing 4WD was active regardless of what mode you selected, no warning lights appeared, and you felt your safety was at risk due to difficulty turning while stuck in 4WD. The dealer says the repair isn't covered under warranty. Fixing this will require replacing the external 4WD mode selector switch.

Your truck has a significant delay when you accelerate from a stop, sometimes lasting 1-2 seconds, which makes driving unpredictable at intersections and stop signs. You've noticed this problem has been happening since you purchased the vehicle and isn't normal. A mechanic will need to diagnose the fuel system and engine response timing to identify what's causing the hesitation.

Your engine hesitates and responds slowly when you accelerate, especially when merging onto the highway from your driveway. This delayed throttle response has nearly caused accidents because you can't accelerate quickly enough to safely merge into traffic. The issue may be related to fuel delivery, air intake, or engine sensors that need diagnosis and repair.

Your truck hesitates and feels like it's about to stall when you accelerate from a complete stop, then suddenly accelerates normally. This delay can be dangerous when you need to quickly merge into traffic or cross lanes. The issue appears to be related to how the engine responds during initial acceleration, and fixing it may involve diagnosing the fuel or ignition system.

Your 2023 Toyota Tundra's sunroof glass spontaneously shattered while parked, shortly after you closed the driver's door—security video shows the sunroof panel visibly flexing under the door pressure before it exploded outward. The glass broke into shards across the sunroof liner with no prior warning signs, impact marks, or objects nearby that could have caused the damage. While this occurred while parked, you're concerned it could have caused injury or accidents if it happened while driving with passengers inside. The repair will likely involve replacing the entire sunroof glass panel and inspecting the sunroof frame for structural damage.

Your truck hesitates when you press the accelerator from a stop, causing a delay in acceleration that has nearly caused a collision. This problem happens randomly and unpredictably. The issue may involve the fuel delivery system, transmission response, or engine control components that need diagnosis and repair.

Your tailgate can come loose from its hinge when you lift it from the passenger side, causing it to fall unexpectedly with its full weight. This happened to your truck, and while there was only minor cosmetic damage this time, the lack of hinge protection could cause serious injury if it happens again. The fix would likely involve inspecting or replacing the tailgate hinge assembly and potentially adding protective hardware to prevent accidental disengagement.

Your fuel gauge may not be reading accurately—it showed full when your tank was actually half empty, and when you filled up at a gas station, it only took about 16 gallons despite the gauge showing full. This could be dangerous while towing a boat, as you might run out of gas unexpectedly. Your Toyota dealer reset the gauge but found no underlying problems. The fix likely involves diagnosing the fuel gauge sender unit or instrument cluster to ensure accurate fuel level readings.

Your engine may stall while driving and produce knocking noises. Toyota has issued a recall for this issue. The problem may require engine repair or replacement of internal engine components.

Your Tundra's infotainment system requires you to enter a 6-digit PIN every time the vehicle loses internet connectivity, which interrupts your navigation display and forces you to look away from the road. This happens repeatedly whenever connectivity drops, even though other navigation apps like Apple CarPlay don't require re-authentication. The owner believes this design creates a safety hazard by distracting drivers during driving. Addressing this would likely require Toyota to update the infotainment software to handle connectivity interruptions more gracefully without requiring PIN re-entry.

All four windows on your truck have poor seals that allow water to leak into the doors, and you're noticing condensation inside the cab on the windows. When the windows are wet, they move with a jerky motion when lowering, and the rear windows feel extremely loose, which could be a safety concern for rear passengers. The dealer's repair technician confirmed this is a defect by reproducing the same issue on new trucks on their lot. Fixing this will likely require the dealer to replace or adjust the window seals and regulator mechanisms to ensure they operate smoothly and seal properly.

Your 2023 Tundra has had multiple unresolved issues for the past 4 months despite being under recall. Your tailgate doesn't close properly, your tire pressure warning light stays on even though your tires are fine, and you're concerned about driving the vehicle long distances. The owner is requesting either a refund or a replacement vehicle due to these ongoing problems.

While accelerating onto a freeway, your truck's power suddenly decreased and the check engine light came on. After pulling over, turning the engine off for a few minutes, and restarting it, the light disappeared and the truck ran normally. This loss of power during highway merging created a safety concern, though you were able to safely move out of traffic.

When you accelerate from a complete stop, such as at a red light turning green, your truck suddenly loses power and won't accelerate through the intersection. This creates a dangerous situation because vehicles behind you may not have time to react to the sudden lag. The issue may involve a fuel delivery problem, transmission hesitation, or engine response delay that needs diagnostic testing.

Your truck's engine hesitates or feels sluggish when you press the accelerator, causing a noticeable delay before it responds normally. This throttle lag makes the truck feel less responsive than expected during acceleration.

Your dash camera stops working and shuts down whenever a warning alert goes off. The camera fails to function properly when it receives warning notifications from your vehicle.

Your engine hesitates during acceleration or when you press the gas pedal. The engine may stumble or lag before responding normally. This could be caused by fuel delivery issues, spark plug problems, or sensor malfunctions that may need diagnosis and repair.

Your climate control system's fan doesn't blow harder when you increase the fan speed setting, even though you can hear the fan motor speed up. The dealer has confirmed this happens repeatedly and Toyota says it's either working as designed or a known issue, but no fix or manual update has been provided. This prevents you from manually controlling airflow to cool or heat the cabin more effectively. A repair would likely involve updating the climate control software or replacing the blower motor control module.

I have been informed that my vehicle was affected by the recall involving the machining debris and therefore unsafe to drive.

Your fuel gauge is reading full even though your tank is only half full when your truck is parked on a slight uphill slope. The gauge has been stuck on full for several days, and the dealership wasn't able to fix it. This could make it difficult to know how much fuel you actually have and risk running out of gas unexpectedly.

Your truck's payload capacity sticker appears to be incorrect. When you calculated the payload (gross combined weight minus curb weight), the numbers don't match what's printed on the sticker, and there are no added options that would explain the difference. The Toyota dealership confirmed they see the problem but said they don't know how to fix it.

Your truck's stereo volume doesn't automatically mute when a text message arrives and is being read aloud through the speakers. This means the message audio competes with your music or radio, making it hard to hear the text being read.

I backed out of my drive way and then proceeded to the stop sign at the end of my street which is three houses from mine. Turned left off of [XXX] onto [XXX] I started to accelerate to speed limit which is 25. I then looked at speedometer it stated I was going 15 MPH then all of a sudden my truck accelerated to almost 69 MPH then my truck slammed in the brakes.
