2023 Toyota Sequoia Hybrid

Formal complaint that 2022 thru 2025 Toyota Sequoia equipped with the 3.4L twin-turbo V6 engine architecture (V35A-FTS) suffering from the notorious main bearing failure be included in the current recall of 2022 thru 2025 Toyota Tundra. If the engine block mechanically seizes, the entire drivetrain locks up, rendering the hybrid backup ineffective, creating a major safety issue. (NHTSA Campaign 25V767)

I am creating this complaint because my vehicle has not been included in the NHTSA recall # 25V-767 on the V35A 3.4L twin-turbo V6 in my 2023 Sequioa. My vehicle was produced on the same manufacturing line and likely had the same engine debris. Toyota gives the reason for not including the hybrid because it is not a safety issue as the hybrid motor can provide power if the engine fails. However owners who have encountered this issue in a hybrid tundra or Sequioa has said that power-steering and control systems failed creating a safety issue. Additionally we use this vehicle to do long road trips that often put us long distances from any service center or roadside assistance. This creates an additional safety hazard for our family being stranded far from potential help due to this issue. Since this is a known issue covered under a recall for other models with the same issue I am asking that my vehicle be included in the recall so that we can have confidence to use this vehicle as intended. We bought a Toyota and a lifetime Toyota owners due to the reputation of reliability that we could depend on the vehicle to get us across the country in safety. Not including our vehicle in this recall is breaking the trust that we have in the brand to do the right thing to cover their mistakes. I am requesting that the recall be consistent to cover all the engines impacted by manufacturing debris including the hybrid variants of the motor.

Electronic control module failed due to the cup holder failing. It is available for inspection. Safety was put at risk because the vehicle randomly slammed itself on the brakes, when in drive the vehicle was moving backwards then abruptly braking and moving forward. The problem was confirmed by the dealer. There were warning lamps for the following: drive start control malfunction, parking brake unable to disengage, hybrid system failure, check engine, parking support brake malfunction. The vehicle was showing as being in both park and drive at the same time. The dealer determined the cupholder allows water condensation to leak into the center console compartment where exposed high and low voltage wiring is contained as part of electronic modules causing the vehicle to malfunction. The vehicle was put in gear while throwing the malfunctions, however, the electronic components should not be exposed and stored within a compartment where liquids are known to be stored (cup holder) in a way that allows water to leak into them. This could happen while the vehicle is being driven and cause serious issues. This same issue happened once before several months back before the cup holder started to fail, so regardless if the cupholder is working properly, it seems water can penetrate this area of the vehicle and cause issues because there is no barrier between the electronic modules/wiring and the cup holder drip tray. The service department actually stated to me that they see this issue all the time on the Sequoias and Tundras.

Vehicle vibrates above 45mph. Took it to dealership and they did not fix the issue. Lane departure warning had to be disabled as it is mistaken for an actual lane departure. Vehicle posses a risk to operator and other drivers on the roadway. Toyota corporate notified but disregarded claim as dealership advised they were unable to replicate.
