2026 TOYOTA TUNDRA Complaints

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!

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?

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.

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.

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.

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.

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.

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.

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.

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.
