2026 Toyota Tundra problems

POWER TRAIN

When you almost stop but then hit the gas there is a dead petal. The vehicle doesn’t accelerate. Then you almost get t boned. They know about the problem but say everything is fine. It’s traction control. It is not. I guess I will have to sue if I survive the crash.

ELECTRICAL SYSTEM

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.

POWER TRAIN

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.

UNKNOWN OR OTHER

Bought my vehicle brand new on January 2026. During heavy rain, my truck has a strong water leak that comes out of the handle bars between the windshield and front door windows, behind the rearview mirrors and the sun glasses compartment. I’ve brought my vehicle to the dealership 3 times already and couldn’t fix the issue or duplicate the water leak. After the third visit at the dealership, i couldn’t find out if the leak was fixed since it has not rained since then. So i went ahead and washed my vehicle and sprayed the top and front of my vehicle. As i went in my truck, i saw water leaking again.

UNKNOWN OR OTHER

Rear sunroof window exploded out while driving. Truck had just under 9000 total miles on it when this happened. Driving on I25 east of Casper Wyoming in very high cross winds. No other vehicle was within a quarter of a mile when the roof exploded with a VERY loud bang!

POWER TRAIN

From date of purchase… when truck accelerates from dead stop, drive train shudders for several seconds before fully engaged. Suspect issue related to software, hybrid enterface with drivetrain, torque converter not locking up. Dealer verified condition with test drive. Concluded it was operating normally. I don’t buy this explanation. Is it going to fail me entering traffic? Will it get progressively worse?

VISIBILITY/WIPER

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.

POWER TRAIN

The vehicle is either unresponsive or has a severe throttle delay from a stop or a very low speed, creating is a major safety issue. This could leave the vehicle in a position to not be able to accelerate, and risks becoming a hazard to other traffic, particularly at intersections. Understanding that a TSB is available for a transmission code reflash to resolve this issue, dealers are denying the repairs stating that they are unable to reproduce the issue in their limited test drives. It is not possible to predict when these severe hesitations occur, so reproducing the issue occurs on an unknown basis.

EQUIPMENT

The contact owns an Autokato Mid Rise Scissor Lift. The contact stated that while using the Autokato Mid-Rise Scissor Lift, the ramps failed to function as intended. The contact inspected the ramps and determined that the ramps were partially welded. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that the Autokato Mid-Rise Scissor Lift had been discontinued.

ENGINE

I was turning left from a stop sign on to a busy road. Immediately after beginning to pull out, the engine stalled and left the truck powerless in the middle of the intersection. I almost got t boned from vehicles traveling both directions. The truck eventually regained power a few seconds after the stall. I had my wife and toddler with me and the situation could have been bad. I no longer the trust the truck which sucks being that it has 2500 miles. Searching online, many owners have had this happen and Toyota refuses to do anything meaningful. This needs to be recall before someone gets hurt, or worse. I’ll be taking the truck in but am doubtful anything will come of it from the dealership.

SUSPENSION

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.

SERVICE BRAKES

The Anti-Collision System / Automatic Braking System engages, even when turned off. This is a major safety hazard and nearly got me into an accident. With the ACS disengaged, poking the front end of the vehicle out into oncoming traffic while trying to merge, the vehicle locks up completely, disabling the vehicle, rendering it a sitting duck in oncoming traffic.

VEHICLE SPEED CONTROL

After stopping at a stop sign and waiting for a clearance, the truck did not respond to throttle input for what felt like 2-3 seconds. The temperature was about 80 degrees, and I had already been driving for 30 minutes when this happened.

ENGINE

The engine in my 2026 Toyota Tundra has significant throttle delay/lag when its cold - even if I let it warm up - it still has significant delay in throttle response - the truck has poor light throttle response and then lurches (even with the most minute progressive throttle input). This almost caused an accident where I nearly got T-boned because the vehicle crept a bit and then suddenly lurched quickly. The vehicle was also hesitant to reach 60mph (even though it was warmed up) after about 10 minutes of driving the vehicle started operating normally. I have a concern for safety everytime I drive this vehicle.
