Consumer Description
I am writing to bring attention to a critical safety issue affecting the 2012 Toyota Prius and other Toyota models equipped with the brake booster and actuator system. These components are failing at alarming rates, leaving vehicles with no functional brakes, ABS, or traction control. Additionally, this failure compromises the hybrid system due to the regenerative braking no longer working, potentially causing further damage to hybrid components and resulting in repairs costing several thousand dollars. Toyota issued Customer Support Program ZJB, which covered these issues for a limited period. This program was in effect from August 31, 2021, with no mileage or year restrictions, but offered secondary coverage for up to 10 years or 150,000 miles from the vehicle’s first use. Unfortunately, my vehicle, with approximately 130,000 miles and 12 years of age, was denied coverage when brought to a dealer after the program had ended. Despite the brake booster and actuator failing, the dealership did not advise me not to drive the vehicle, further emphasizing the gravity of this oversight. This is a significant safety hazard, as vehicles with these failures lack the ability to stop effectively, risking lives on the road. Furthermore, this problem is not isolated to my Prius; it affects thousands of Toyota vehicles equipped with these components. The estimated repair cost exceeds $3,000, an undue burden on owners for an issue that stems from defective manufacturing. I firmly believe Toyota’s decision to address this problem through a limited Customer Support Program, rather than a full recall, is inadequate and irresponsible. This issue meets the criteria for a safety recall and should be treated as such by the National Highway Traffic Safety Administration (NHTSA). I respectfully urge the NHTSA to investigate this matter further asap/mandate a recall for all affected vehicles. This is a big safety issue.
