A few weeks after purchasing this vehicle in Dallas, TX we drove to Florida. About 4 hours into the trip we stopped for lunch and noticed both of our cells phones had not charged and in fact had discharged quite a bit. Further testing shows none of the front or rear USB Type-C ports would charge any cell phone we plugged into them. I purchased a USB volt meter and verified that the car would only send a small fraction of an amp to any cell phone plugged into these four ports. After discussing it with the dealer we tried different phones, different cables, and even every new Toyota on the show room floor. No single vehicle's front or rear Type-C ports would charge any cell phone we tried. Since then we have tried 4 friends Lexus vehicles and found the same issue exists in all of them. Any Type-C port labeled with a lightning bolt (i.e. a charging port) will not charge any phone we've tried. Any Type-C port that is marked as a data port will charge the phone. We have tried 5 different Samsung and 3 different iPhones and none will charge in the Type-C ports marked as charging ports. All phones and cables we've tested work with all home chargers and every other vehicle make and model we've tested with. The Samsung phones we have quick access to and originally used in testing are S21, S24, and A54. The iPhones are about two year old models.

The Toyota Crown Signia Tire Pressure Monitoring gauge has to be reset to properly display on each start versus staying in place on the drivers monitoring dashboard. All other driver monitoring aids, once selected to display on the monitoring dash, stay in place per each start cycle. This has existed as a vehicle defect from day 1. Many others have noted the same issue on various Crown Signia bulleting boards. The tire pressure monitoring is important as this vehicle has: 1. No spare, and weighs over 4,200 lbs. 2. The limited model in on 21 inch rims, and runs 235/45R21 tires, ie., very low profile. As such, this should be fixed immediately to ensure this critical information, once set up for monitoring, stays in place for driver monitoring.

When leaning on the front seat center armrest, the armrest makes a clicking noise when hitting rough or bumpy roads. The Toyota dealer replaced the armrest, and the same issue occurred. Toyota told the dealer they want the part to investigate further.

While driving less than 10 mph, (slightly down hill) approaching the house garage, the car suddenly accelerated and the brake was applied to stop but the car continued and smashed through the garage door, proceeded through garage, smashed through the back of garage, hit a Weber gas grill, proceeded over a low-level deck and hit a large tree. The impact force of the car (left front) against the tree caused the car rear end to rise up and move 30 degrees to the right and land on the low-level deck. The driver was the only person in the car and suffered a broken right wrist and contusions to her chest. Both Front air bags did not deploy, side air bags did deploy. There was no warning given and the Car collision avoidance system did not stop the car. The damage to car was total. Car Emergency Voice activated and assisted in notifying ambulance and police. Insurance has reviewed the damage, but I am not aware that they are investigating for cause. There has been one other sudden acceleration reported of a 2025 Crown Signa. There is history of malfunctions of the Electronic Throttle Control (ETC) (per Google). There is an Event Data Recorder (EDR) on the car, but I don't know what is on it. This needs to be investigated. (If this unintended acceleration happened in a grocery parking lot, or on a highway, there could have been serious injuries or a death).

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.

The air conditioning dye injection tool kit has been developed to aid in identifying the location of air conditioning refrigerant leaks. The procedures outlined in this Service Bulletin aid in locating, inspecting, and repairing refrigerant leaks.

To assist with the early detection and early resolution of audio related concerns you may be asked to recover MMR data from the head unit. The following steps are instructions on how to retrieve the data from the system and are only to be used when requested by FTS and/or FPE.

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.
