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.
The contact owns a 2026 Toyota Tundra. The contact stated that while driving at an undisclosed speed through a tornado, the steering and braking systems became inoperable. There was no warning light illuminated. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 6,000.
Brake system failure at less than 50 miles. Dealer providing minimal information red brake warning lamp, brake fluid low error message, and "braking power low" message being "stop in a safe place".
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.
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.
