2008 Toyota Highlander service brakes problems

“Subject: Sudden Unintended Braking and Loss of Vehicle Control – 2008 Toyota Highlander V6 AWD I am reporting a serious and potentially life-threatening incident involving my 2008 Toyota Highlander V6 AWD. Shortly before this incident, I had all four tires replaced at Les Schwab. While driving approximately at highway speeds, with my foot on the accelerator and absolutely no pressure on the brake pedal, I suddenly heard a knocking sound and felt the vehicle jerking violently. It felt similar to ABS activation, although I do not know what system was responsible. I stopped and inspected everything finding nothing wrong so proceeded to drive the car back home. The vehicle then suddenly and forcefully applied the brakes without any input from me. The rear wheels appeared to lock, causing the tires to skid. The back end of the vehicle fishtailed and began attempting to spin around. I struggled to maintain control. There were three children riding in the vehicle with me. All four occupants were placed in immediate danger. After stopping, I shifted into Park and then back into Drive. The brakes released, and the vehicle began moving normally again. However, I…”

“THERE WAS NO INCIDENT. WHEN THE BRAKE MALFUNCTION SCREEN DISPLAYED, I DROVE THE VEHICLE TO THE NEAREST TOYOTA DEALER IN PUEBLO, COLORADO. I RECEIVED THE ATTACHED SERVICE MESSAGE AND PICKING TICKET; 17june2025. IT ALSO NEEDS NEW BRAKE PADS, ROTOR ADJUSTMENT, AND 5 NEW TIRES. TOTAL~$6000. WAY TOO PRICY! I PAID FOR THE DIAGNOSTIC TEST, AND DROVE HOME CAREFULLY! THE VEHICLE HAS BEEN SITTING IN MY CARPORT SINCE, AND I AM WALKING THE CITY LIMITS FOR ALL PURPOSES. THE 12V BATTERY DIED MID-JULY, WITHOUT REPLACEMENT SINCE. I LIVE IN LA JUNTA, 70 MILES EAST OF THE DEALER. SO WE'RE LOOKING AT 99,000 TOTAL MILES AS IT SITS.”

“My 2008 Toyota Highlander Hybrid is having severe issues with the ABS system. Toyota is reporting that it needs an ABS actuator and ABS pump replacements. These were a part of Toyota's previous Customer Support Program, but the program expired before I owned the vehicle. That is EXTREMELY dangerous and the issue with the ABS system should be considered a Safety Recall that is ALWAYS available to Toyota customers to rectify and paid for by Toyota. It is a BRAKING ISSUE. It is not just brake pads, or normal wear and tear. This is a known issue and regardless of the timeline, Toyota should absolutely pay for the repair.”

“Good Afternoon, The brake actuator and booster pump failed on my 2008 Toyota Highlander Hybrid. ABS, Brake, and VSC warning lights came on, and the brakes became weak and unsafe. A repair shop confirmed the issue with codes C1252, C1256, and C1391. I tried to fix it at a local shop last year, but the problem came back. It seems this repair can only be fully done at a Toyota dealer due to software requirements. However, the dealer repair cost is very high. I cannot afford the repair or a new car right now because of family budget limits — we have three children and rely on this vehicle every day(only one car). Toyota declined to help, even though I later found this issue was once covered under Program ZKC, which I missed. The vehicle is still unsafe and available for inspection. Thank you very much for considering my issue!”

“In June 2019, Toyota issued a recall for ABS malfunction, diagnostic code C1391 - brake actuator and accumulator. New parts were issued by Toyota in 2019 as part of the recall. My vehicle experienced ABS malfunction, diagnostic code C1391 in March 2022 and was repaired by Toyota with the new and improved parts issued as part of the recall. As of October 14, 2024, my vehicle is experiencing the same issue again - ABS brake malfunction diagnostic code C1391, with the brake system light, master warning light, abs light and ABS Malfunction warning noted on the screen. The vehicle can be inspected. Toyota has inspected and confirmed it is the same issue again. The new and improved parts from 2019 should not fail within 20,000 miles. Toyota did confirm that they used the new parts issued as part of the recall and cannot explain why they failed faster than the original parts causing dangerous braking issues.”

“We were driving at about 40 MPH and approached our turn. When I depressed the brakes, they felt spongy and I had trouble slowing quickly. The yellow triangle illuminated on the dash and a long warning beep sounded. I was able to get safely parked in a parking lot, and my son came and took a look as well. We had the car towed to a shop, who diagnosed the problem, stating that we needed to replace the brake booster pump and actuator assembly. A family member noted that Toyota had issued a recall for vehicles with the same year/make/model for the braking system, so we had it towed to our local Toyota dealership to verify that they had no open recalls on the brakes and complete a full inspection otherwise. They validated that the brake booster pump and actuator assembly needed to be replaced. I am left wondering why my vehicle was not included in Toyota's recall.”
