By slapping the hardware on the compromised plastic, they performed an incomplete repair that violates Toyota's legally binding instructions filed with federal regulations. They refused to replace the physically compromised bumper structure during the 23TA12 recall remedy. The dealer actively short-cutting a safety recall. Furthermore, t

• What component or system failed or malfunctioned, and is it available for inspection upon request? The UA80 8-speed automatic transmission assembly (specifically internal mechanical wear resulting from front carrier assembly bearing degradation/torque converter heat buildup). No, the component and the contaminated transmission fluid are currently being replaced at the dealership. • How was your safety or the safety of others put at risk? The severe mechanical wear and metal-on-metal degradation inside the transmission create an imminent hazard where the vehicle can experience sudden slipping, severe hesitation, or a complete, unexpected loss of motive power while traveling at highway speed
