“I travel to work one hour away from home, on high speed highway's my break system lights turned on, traction, ABS and break, break pedal sinks and will not break and is very dangerous when driving home. I hope no one gets killed”
NHTSA complaint #11385667, filed 2020-12, 134,000 miles“The break booster started making a noise and my car should have fallen into the range of the previous recall for the exact part. I cant afford to change it so I continue to drive it and all of sudden the breaks are so hard to push and a constant buzz is going off! Autozone confirmed it was the break booster ans abs then a private shop did also”
NHTSA complaint #11528769, filed 2023-06“My Prius 2010 has thrown the ABS, Traction, and Brake HUD lights all together. I took it to an Autozone and scanned the code to get the C1391: Abnormal Leak of ACC PRESS error. Many Prius 2010 have this issue, I'm sure I'll need to replace the actuator and/or accumulator and I know that will cost a good bit, i hope Toyota could help us fix it.”
NHTSA complaint #11520320, filed 2023-05“I am writing to express my concern regarding an issue with the PCS System dash lights on my 2010 Toyota Prius. I recently became aware of problems related to the brake booster system, which I understand have been addressed through recalls or warranty extensions on certain models. I believe that the issue I am experiencing should be covered under warranty, and I kindly request your assistance in resolving this matter.”
NHTSA complaint #11648229, filed 2025-03“Brake, ABS and traction control warning lights went on when I was driving. I was able to brake but it was not functioning at 100%. The local mechanic was able to scan the code to get the C1391: Abnormal Leak of ACC PRESS error. The warning lights remain when I drive or parked. I no longer feel safe driving my vehicle. I plan to take my car to the Toyota dealer for further diagnosis and repair. I was informed that this is a very costly repair.”
