Accident Video: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
On [XXX], while driving on a highway with two young children, the dashboard lit up with multiple lights and error warnings. This appeared without warning and with no incident, and the warnings included the main hybrid screen reading “Check PCS System”, triangular Master Warning Light, Brake System Warning Light, Brake Warning Buzzer, ABS Warning Light, and Slip Indicator. We immediately pulled over to the side of the highway to check for any major damage or leaks, but found nothing unusual. We booked a diagnostic with a Toyota service center, where we were informed that brake system error code C1391 was discovered and the service recommendation was to replace the failed (leaking) brake booster and booster pump assembly. The service representative informed us that this exact system failure was previously covered by a Toyota Customer Support Program due to a known faulty part, but the primary coverage date ended in August 2021 and we just barely surpassed the 10-year secondary coverage date of February 2023. We were urged to repair it right away and were told that the vehicle is unsafe to drive in the current condition, as the Antilock Braking System could fail at any time. We have noticed that it takes more pressure to brake the vehicle than prior to the issue, which may have been began deteriorating prior to the issue but was difficult to identify due to the slow progression. We brought the vehicle home with hopes of resolving the matter with Toyota customer engagement. They confirmed that this issue affected almost 1 million vehicles, but because it was a customer support program and not a recall, they could not help us since we were past the 10-year mark (yet well under the 150,000 mile limit to the program). The vehicle still has all the lights described above, and as such is concerning to drive. A second vehicle is critical for our family, so to be suddenly told that our vehicle is unsafe to drive but the defect wasn’t a full recall is concerning.
