I purchased my 2023 Prius new which comes with a 5 year 60k mile powertrain warranty. My car, at 42.2k miles, has developed a clicking sound when the steering wheel is fully turned to the left and the vehicle is moving slowly. I brought it to the dealer today Oct 2, 2026 and their technician was able to reproduce my concern. However I came across two problems: 1) Their technician claims it is a "suspension" issue and 2) I was told even if it were CV related it would not be covered under warranty. Toyota is aware of this clicking sound and even has multiple bulletins about this exact same issue on their other vehicle models, all of which are covered under the 5 year 60k mile warranty. For example: T-SB-0106-20: "Some 2015 – 2021 model year Corolla vehicles may exhibit a clicking noise when making turns greater than 90 degrees and accelerating with the steering wheel on full lock, such as when performing a U-turn" Other bulletins include: T-SB-0053-25 and T-SB-0028-26. My research shows that suspension related issues are diagnosed with symptoms such as a single clunk sound when hitting bumps or driving over uneven pavement whereas CV issues are diagnosed with symptoms such as rhythmic clicking as the car accelerated through a turn. And upon reading my manual, I confirmed that CV issues are covered by the 5 year 60k mile warranty.

What component failed: The rear plastic trim on my 2023 Toyota Prius cracked without any impact, accident, or external cause. The component is still on the vehicle and available for inspection upon request. Safety risk: While this is primarily a structural/cosmetic defect, cracking plastic trim that was not caused by the owner suggests a broader manufacturing quality issue. If this type of failure occurs in components closer to safety systems, it could pose a more serious risk. Confirmed by dealer: Yes. I brought the vehicle to a Toyota dealership and service center (Berkeley Toyota) for inspection. They confirmed the cracking. The vehicle was purchased at Livermore Toyota. Other inspections: The vehicle was inspected by the Berkeley Toyota dealership and service center. No other parties have inspected it at this time. Prior warning signs: None. There were no warning lights, sounds, or symptoms before the crack appeared. It was discovered suddenly with no preceding indicators.

Body / Liftgate The rear hatch unexpectedly dropped and fell on my head while the vehicle was stationary. The right-side rear hatch gas strut separated from the body at the mounting point. The left-side rear hatch gas strut had also shown signs of imminent failure and subsequently broke near its mounting point. This resulted in loss of hatch support and uncontrolled closure, creating a risk of head and upper-body injury. The failure appears related to structural stress at the strut mounting locations, not misuse. Seat Belt – Rear Center Passenger The rear center passenger seat belt upper cover can be easily pulled off by passengers, which breaks the plastic retaining tab. When the tab breaks, plastic fragments fall into the seat belt mechanism, causing the belt to jam and fail to retract properly. This results in impaired seat belt function, which is a safety concern for rear passengers. The vehicle has not been modified, and the failure occurred during normal use. Vehicle mileage at time of incident was approximately 150,000 miles. The rear center passenger seat belt issue has been present since the vehicle was new. The rear center passenger seat belt mechanism was replaced twice by the dealer during the warranty period, with one replacement performed as a goodwill repair after Toyota Corporate declined coverage. Despite these repairs, the same issue reoccurred, indicating a persistent design-related vulnerability rather than isolated misuse. The issue results in seat belt jamming and failure to retract, which is a safety concern.

Flash reprogramming allows the Electronic Control Unit (ECU) software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Global Techstream+ (GTS+) ECU flash reprogramming procedures and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard+ (CUW+). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU will initialize the flash reprogramming sequence. This bulletin also details the process for acquiring a Security Signature from TIS during the GTS+ ECU flash reprogramming process.

OBSOLETE NOTICE February 27, 2026: This bulletin is no longer applicable and is now obsolete.

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.

Some ECUs can set a DTC that is common with other ECUs. This can lead to accidental use of the wrong repair manual when diagnosing these type of DTCs.
