NHTSA Complaint #11639446 — 2010 TOYOTA PRIUS

Dear NHTSA Team, I am filing a safety complaint regarding my 2010 Toyota Prius (VIN: [XXX] ) due to ongoing brake system failures. My vehicle is affected by Safety Recall D0H (Brake Booster Pump Assembly – Accumulator), but Toyota refuses to replace all necessary components for a proper repair. Issue Summary: •My brakes have intermittently failed, requiring excessive pedal pressure and causing delayed stopping, putting me at serious risk. •I took my car to Toyota on Edens for the recall repair, where Service Advisor David confirmed that the brake booster and accumulator should be replaced together. •However, Toyota will only cover the accumulator under Recall D0H, despite the brake booster being critical for safety. •My vehicle has Diagnostic Trouble Code (DTC) C1391, indicating an internal leak in the braking system, but Toyota refuses to cover the booster replacement. Toyota’s Response: •I contacted Jessica from Toyota’s Customer Experience Center (Case Number: [XXX]). •Toyota refuses to replace the booster under the recall, leaving me responsible for the cost, even though the dealership confirmed it’s necessary. •This decision leaves my car in an unsafe condition even after the recall repair. Request for NHTSA Action: 1.Investigate the safety risks related to this recall and the necessity of replacing both the booster and accumulator together. 2.Ensure Toyota properly covers all necessary brake repairs for affected vehicles. 3.Expand or modify Recall D0H to include the brake booster, as it directly affects braking performance. I urge NHTSA to take action before this defect leads to accidents or injuries. I am available to provide additional information as needed. Thank you for your time and attention to this urgent matter. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
