2023 Toyota Sequoia Hybrid problems

POWER TRAIN

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)

ENGINE

The motor in our 2023 Toyota Sequoia with around 32,000 miles failed and left me stranded on the side of a two lane highway in the middle of the night. Toyota only wants to replace the engine block and will not extend the warranty on the motor after it is repaired. This is the same motor that is in the Tundra that was recalled (NHTSA recall #25V767 for the V35A 3.4L i Force Max twin turbo V6 hybrid). Why is there not a recall on the Sequoia's motor? Now I will have a motor that has been torn apart and put back together by some random technician instead of getting a brand new motor from the factory, which is what they did for the Tundra. Toyota also extended the warranty on the motors for the Tundra, which they will not do on my rebuilt motor. So now if this motor they rebuild lasts as long as the first motor it will fail right after my warranty expires and I will have a Sequoia with 64,000 miles that has no motor and I will have to pay to have it replaced.

Around 63,xxx miles the force max 3.5 l twin turbo v6 hybrid displayed P0521 engine oil pressure switch and P0524 oil pressure to low 2 miles from my house. Sent to toyota on 1 June, engine blown. It has been 19 days and Toyota still hasn't made a decision on "good will" coverage. My wife calls every other day and it car has went thru 2 different teams worth neither of them calling the dealer for information. Desert toyota of tucson is trying to help but toyota is ignoring our claims. I'm a disabled veteran and this is our family primary means, we have not been provided a rental or anything. Very frustrating and a guy punch passing for this expensive unusable vehicle. From technician: Engine scanned for DTCs; found low oil pressure. - Oil sample taken; revealed metal flakes indicating internal engine damage. Recommendations: - Engine assembly due to internal damage detected.

STEERING

I would like to create a complaint because my 2023 Toyota Sequoia is not included in the NHTSA recall #25V767 for the V35A 3.4L i Force Max twin turbo V6 hybrid. My Sequoia was manufactured on the same production line as engines that have been recalled for engine debris in the Tundra trucks and Sequoia's. Toyota's reasoning for not including my hybrid vehicle is it's not a safety concern as the hybrid electric motor will provide power if the V35A gasoline portion of the engine should fail. Owners of the Tundra and Sequoia have stated that with loss of engine power some control system fail creating a safety issue. I use this vehicle for towing our boat to and from the lake frequently. I travel long distances with family and stranded along the highway could be catastrophic. This is an issue that Toyota is obviously aware of since they recalled the V35A engines because of failure.

POWER TRAIN

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.

STRUCTURE:BODY

The factory (OEM) roof rails on my 2023 Toyota Sequoia have become loose at the front and are popping up, no longer sitting flush or appearing securely attached to the roof. This issue occurs during normal driving and is visible without removing any trim or components. The front portion of the OEM roof rails appears to lift or separate, creating concern that the rails or associated hardware could detach while the vehicle is in motion. This presents a potential safety hazard due to the risk of parts coming loose at speed and becoming road debris, which could endanger other vehicles. I am aware of other owners reporting similar issues with the factory roof rails on this model, suggesting this may not be an isolated incident. The vehicle has approximately just over 40,000 miles. The dealer has inspected the vehicle and advised that the repair would require significant disassembly and replacement, with an estimated cost of approximately $3,400. Despite the issue involving OEM components and their secure attachment to the vehicle, the repair was denied under warranty due to mileage. Given that this involves factory-installed exterior structural components becoming unsecured, I believe this represents a potential safety-related defect rather than normal wear or damage.

UNKNOWN OR OTHER

Sunroof spontaneously shattered while driving the vehicle. Sounded exactly like a gunshot. Luckily I remained calm while driving and heart racing. It was 9:20 at night and no other cars around. I am absolutely certain that nothing hit or touched my car.

SERVICE BRAKES

This is related to Toyota service bulletins T-SB-0043-24 and T-SB-0022-25. My brakes started squealing shortly after I purchased the vehicle. I reported this to my toyota dealership. They told me about the service bulletins, but said the parts are on back order. I have been waiting for almost 2 years, and the dealership still hasn’t fixed it. Now, my brakes are vibrating violently at highway speed, and my family is scared to ride in the vehicle.

POWER TRAIN

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.

VISIBILITY:REARVIEW MIRRORS/DEVICES

The rearview mirror in my 2023 Toyota Sequoia is a digital camera-based system rather than a traditional reflective mirror. The issue is that the camera used for this system has a low resolution and performs poorly in low-light conditions, making it difficult to see clearly at night. This creates a significant safety risk, as rear visibility is crucial when driving at night, especially when changing lanes, reversing, or maneuvering in areas with limited lighting. Toyota has since introduced an improved, higher-resolution version of this camera in newer models such as the Toyota Tacoma, which provides significantly better night visibility. However, despite acknowledging the issue and investigating potential solutions, Toyota has stated that the newer, higher-quality camera is “not compatible” with the Sequoia and therefore cannot be retrofitted to address the problem. This issue has been raised with Toyota, and their investigation confirmed the problem. However, they have not provided a solution or corrective action for existing Sequoia owners. The problem is consistent and has been observed repeatedly in nighttime driving conditions. The vehicle has not displayed any warning messages or error indicators related to the rearview camera system. Given the importance of rear visibility for safe driving, the poor performance of the current system presents a potential hazard to drivers and other road users. A malfunctioning or inadequate rearview camera system increases the risk of accidents, particularly in low-light situations where the driver is relying on it for visibility. I request that this issue be reviewed and addressed to ensure that affected vehicles are equipped with safe and functional rearview systems.

SERVICE BRAKES

please refer to NHTSA issue 11624149. Toyota has dismissed my complaints about the trailer brake controller and has (twice now) closed the complaint I have filed with them regarding the issue I am having with the trailer brake controller. Even though I have been able to reproduce the CPU programming issue with the trailer brake controller with a Toyota Service Technician, Toyota corporate has decided to not move forward with any remedies and has dismissed my concerns. The improper programing on the trailer brake controller in this vehicle is a serious safety issue that should be recalled before an accident occurs and someone is killed.
