2026 Toyota Tundra Problems

When breaking towards a stop and deciding that you can now instead accelerate, you’ll press the gas pedal and the vehicle will occasionally feel like there’s a delay in registering that you want to accelerate instead of continuing to break

Since taking delivery of this brand new 2026 Toyota Tundra Hybrid, I have experienced a persistent shuddering at low speeds, approximately 15 to 25 mph. The shuddering is most pronounced during slow, gradual brake application — the more gently the brake pedal is pressed, the more severe the shudder. It is also present to a lesser degree during acceleration. The issue appears to involve the transition between the regenerative braking system and the conventional friction brakes in the i-FORCE MAX hybrid system. The vehicle was taken to an authorized Toyota dealership for a first repair attempt. Tires were rebalanced and inflated to 40 PSI, exceeding the manufacturer's recommended specification. The repair order was closed with the notation "test drove and vibration is gone." This conclusion is inaccurate. The shuddering was only partially reduced — the root cause was not identified or resolved. The safety concern is significant. I have found myself instinctively adjusting how I apply the brake pedal to avoid triggering the sensation. A vehicle that changes the way its driver brakes is dangerous. A second repair attempt is being scheduled at the selling dealership.

My 2026 Toyota Tundra TRD Pro developed a sudden, loud knocking noise from the engine at approximately 15,000 miles while I was driving. The engine began running very rough, the vehicle started shaking, and the engine was losing power as I pulled over. The knocking was most noticeable at low RPM and followed engine RPM. There were no warning lights or warning messages before the problem occurred. I was able to safely pull the vehicle off the road, but the sudden loss of engine power and severe shaking created a safety concern. If the failure had occurred in heavier traffic or at highway speed, the loss of propulsion could have created a significant risk to me, my passengers, and other motorists. I stopped driving the vehicle because I was concerned about a complete engine failure. The vehicle was taken to an authorized Toyota dealership and is currently available for inspection. The dealer has confirmed the abnormal engine noise, but as of the date of this complaint the engine has not yet been disassembled and the exact internal cause of the failure is UNKNOWN. The vehicle has approximately 15,000 miles and is covered by the manufacturer's warranty. I am filing this complaint because the engine problem occurred suddenly at very low mileage and resulted in severe shaking and loss of engine power while driving. I am concerned that this condition could result in a complete loss of propulsion. I will provide additional information when Toyota completes its diagnosis.

I was attempting to enter traffic from a steep driveway. I removed from foot from the brake and pressed on the accelerator, there was no power and the vehicle would not increase speed. This lasted about 2 seconds. It was a 50 mph roadway and the approaching vehicles had to slow quickly to avoid a collision

I bought the vehicle new in November 2025. 2026 Toyota Tubdra TRD SR5. In the first week I noticed a lot of jerking and shaking. I brought it to the dealer and was told it was a break in period and it should go away. I’ve had the truck in the shop 5-6 times since and the jerking and shaking hasn’t gone away. I’m at 6300 miles now. The dealer won’t even respond to me anymore. The only way to make the jerking go away is to step on the gas pedal harder but this has become extremely dangerous because it’s forcing me to go faster than I would like, especially in school zones. The dealers say that it’s the truck running very low RPM’s to maximize fuel efficiency and also because there are 10 gears but is that’s the case than why isn’t everyone experiencing it. It’s worse on cold mornings (40 or below) but it’s almost like the truck needs an hour or two to warm up. Even then it’s still jerking. My guess is that the truck doesn’t know what gear it’s supposed to be in but 4th or 5th gear are the worst where the truck hesitates and jerks. I’ve been told to run it in Sport mode but that doesn’t help. I’m finding more and more complaints about this online with the Toyota Tundra SR5’s and I’m part of numerous groups. Someone needs to step in because no one should have to go through this and it’s very unsafe to have to push the gas pedal down harder to make the jerking go away.Thank you for your time.

I purchased a new 2026 Toyota Tundra on February 25, 2026. Almost immediately after purchase, I noticed a squealing noise coming from the brakes whenever the vehicle was placed in reverse. I brought the vehicle to my selling dealer, who confirmed the noise is caused by a known defect in the brake system, for which Toyota has issued an internal service notice. The dealer told me this defect has not been made the subject of a formal safety recall. The dealer informed me that the repair requires parts that Toyota Motor Manufacturing has been unable to reliably supply. I was told Toyota limited parts distribution to one package per week across all dealerships, and has since suspended distribution entirely after losing its parts supplier, with no confirmed timeline for a new supplier or for parts to become available again. As of this complaint, my vehicle has gone approximately six (6) months without an effective repair, and I have been told the wait could extend beyond one additional year. I have also been told that approximately 75 other customers at my dealership alone are on a waiting list for the same repair, and that this defect affects all 2026 Toyota Tundra vehicles as well as several other Toyota models currently in production. It is my understanding that Toyota has continued to manufacture and sell new vehicles containing this same defective brake component during this period as they don't have an adequate supplier to provide the replacement parts. I am concerned this represents a widespread brake defect that has not been properly disclosed or remedied, affecting a large population of current-production vehicles.

This is a reoccuring issue and happens daily. When the vehicle is cold and sitting all day or all night, on the first 5 minutes of driving or so, when you push the accelerator pedal from a dead stop or rolling stop, there is no throttle/engine response for at least 1.5-2 seconds. This is a HIGHLY unsafe condition and can lead to a traffic collision. I have reached out to Toyota Corporate about this and they said to bring it into my local dealer, Dick Hannah Toyota in Kelso, WA to perform the rolling stop TSB that is out on these Tundra Trucks. I received information from Dick Hannah that when they went to perform the procedures to take care of this TSB, that it had already been done and that there was nothing they could do further. They asked me to document the conditions to try and get Toyota Corporate to do something about it. I asked if there wasn't a recalibration they could do or anything else to make this condition improve, and they said no there is not. I expressed my concerns saying that there is nothing to document, that this happens everyday and is a daily occurence whenever the vehicle has been sitting for a long period of time. I have reached out to other vehicle owners on vehicle forums on the internet that are experiencing the same exact problems with no remediation from Toyota Dealers or Toyota Corporate. I was even offered to get into a split to hire a lawyer to get this unsafe condition remedied. This is a big deal and should not be overlooked and written off by ANYBODY.

Toyota Tundra safety sense 2.5 package (pre-collision warning, lane keeping assist, RSA, etc.) disabled while vehicle was in motion.

The passenger door handle was recently replaced. Inside door handle assembly broke and the passenger was unable to open the door from the inside. Now the driver door handle assembly just broke and I was unable to open the door from the inside. The inability to exit the vehicle from the inside should be a safety recall. Various online forums mention similar issues from other owners. Concern was raised with Toyota but not actions was taken.

According to Toyota, the 2022-2026 Tundra is compatible with 35x11.5 tires. These tires were installed by the dealer before my purchase. However, during turns, the tires heavily rub against the sway bar. This issue may be specific to the TRD upgrade package, which includes an upgraded, thicker sway bar. After driving for just 500 miles, noticeable rub marks have developed on both sides of the sway bar and visible marks on the inside of the tire. Tire rubbing can lead to faster tire wear and may even cause the tire to break during operation if the damage continues over time. I have reported this to Toyota Customer service and all they say they do is file a report.

A significant rattle occurs randomly in between the frame and the rear passengar seating. We have contacted Toyota. Toyota believes it is a "normal road condition" of which would imply it happens every single mile driven. As the rattle can be startling, we have swerved by accident. In addition, Toyota has not fixed the issue and we have been in process of pursuing a settlement for faulty manufacturing. We also believe the Truck is a danger to road as this rattle may mean the frame may come off one day while driving.

While Driving at 75mph there was sudden violent shake of Truck and it was not until I reduced the speed to 55 that it stopped. Then it happened again for the second time in the same day. After a week it is still doing the same sporadic but the truck feels jumping. Took it to the Toyota Dealer and they discarded any tire balance issue and they said they need to recreate the issue in order to be able to diagnose the problem. My concern is safety and that sudden violent shake loose the control.

A minor stone chip instantly escalated into a 12-inch crack that ran all the way to the edge of the glass. The factory acoustic glass is structurally weak and brittle, causing minor road debris to immediately result in a massive crack that compromises the glass integrity on the passenger side view.

While driving, the sunroof suddenly exploded without any external cause. The temperature at the time was approximately 42°F. The glass shattered throughout the interior of the vehicle, with pieces falling into my clothing and all over the cabin.I immediately contacted the dealership and was advised to visit the nearest Toyota location; however, there wasn’t one nearby. I had to cover the vehicle with a tarp to continue my 4 hour drive home. Thankfully, I was traveling alone—had my family been with me, including my [XXX] infant, this could have resulted in severe injury, as glass would have fallen directly on the car seat.The dealership later inspected the vehicle and found no evidence of any outside influence or impact that could have caused the explosion. I’m deeply concerned about the safety implications of this failure and would like to understand how Toyota plans to address this situation, as well as ensure this does not pose a continued risk to other drivers.
