We received this from Toyota. Customer Support Program Bulletin Date: Page: POL19-06 6/6/2019 1 of 3 REVISED 8/28/19 CUSTOMER SUPPORT PROGRAM BULLETIN (ZKC): REPAIR COVERAGE FOR BRAKE ACTUATOR ASSEMBLY AND BRAKE BOOSTER PUMP ASSEMBLY ON CERTAIN 2008-2010 MY HIGHLANDER HYBRID VEHICLE. When we received this bulletin, we asked our Toyota Dealer Service Department (Stevenson Toyota East, Denver, CO) to address this issue multiple times when bringing in our vehicle for service in 2019 and 2020 and were told repeatedly they would not fix this issue since the ABS light was not on. Now that this bulletin is expired the ABS light is on. We took our Highlander to the Toyota Dealership in Melbourne, Florida and were told that this repair will now cost us $2473.89. Our 2010 Highlander is barely worth that, and now we have to repair this on our own even though Toyota knew the brake actuator assembly and brake booster pump would eventually fail at some point in time. Despite this, Toyota refused to resolve this issue when we asked (more than once) right after receiving the service bulletin in 2019 and as a result is causing a safety issue for our college aged son who drives this car, and all other drivers on the road should the ABS system fail. The attached estimate states the ABS service light has not come back on but this is not true and my son is having issues with the brakes.

What 2010 Toyota Highlander owners say
Most recent owner complaints, unedited.
When traveling a slow speeds (less than 15 mph) and needing to stop, the brakes are pressed but do not respond. This has happened on several occasions and has caused two separate accidents where the Highlander has failed to stop and it runs into the car in front. After the first accident, we looked for recalls (2015) and there were none for any model Toyota for brakes or brake systems. We brought the car in to the mechanic and had all the brakes and pads replaced, although they said nothing was wrong with the shoes nor pads. Now, years later, another accident in the exact same way. Luckily, due to the slow speed, no one was hurt but this is definitely a problem with the car. There have never been any warning lights, or sounds that would indicate an issue.
Affected by the faulty Brake Actuator & Accumulator on 2010 Toyota Highlander Hybrid. Brake malfunction and ABS disabled lights popped up on my Multi-Information Display. This issue disables ABS & VSC systems, which therefore makes this a safety hazard. Upon doing research, I have concluded that many complaints about this specific "Brake actuator & accumulator" have been issued. In the past, Toyota has provided a "Customer Support Program" which expired in 2020, but this does not help current owners like myself, who are stuck with this problem.
On approx. October 19, 2023 my vehicle started showing 4 error messages on the display: Brake Malfunction, Check ABS, Check VSC System, and Check Brake System. At the same time, these 5 warning lamps became illuminated: Brake System Warning Light and Warning Buzzer (Red), Brake System Warning Light (Yellow), Master Warning Light (Yellow), ABS Warning Light (Yellow), and SLIP Indicator (Yellow). A car repair technician obtained the following error codes from the vehicle in a diagnosis: C1391 (Abnormal Leak in Accumulator). I was informed that the VSC (vehicle stability control) safety feature of the vehicle is disabled while the error codes and messages are present. Toyota previously issued a customer support bulletin (No. POL19-06) on June 6, 2019, titled "Customer Support Program ZKC: Certain 2008-2010 Model Year Highlander Hybrid Vehicles Coverage for Brake Actuator Assembly and Brake Booster Pump Assembly". In the bulletin, Toyota acknowledged that its 2008-2010 Highlander Hybrid models had "certain internal malfunctions of the Brake Actuator Assembly". Affected error codes include C1391 and C1253, among others. Affected warning lamps consists of all 5 of the warning lamps that were illuminated in my vehicle. Affected parts include 04008-26448 (Actuator Assy, Brake w/ Fluid) and 04008-51148 (Pump Kit, Brake Booster w/ Accumulator). Instead of issuing a recall for this hazardous defect, Toyota opted to offer "Customer Support Program ZKC". The malfunction that manifested my vehicle is not eligible for this program. Toyota should issue a proper recall to address this safety hazard.
1. When braking vehicle accelerates for 1 to 2 seconds. 2. I believe safety is at risk for driver, passengers or people close to accelerating car. 3. This has not been confirmed with dealer. 4. Multiple inspections but not for this problem. 5. No warning has ever appeared on any visible car system. Problem has existed for over one year. 2010 Toyota Highlander Platinum Hybrid 4WD
The brake actuator (4405048320) and brake booster pump (4707048020) malfunctioned. The ABS warning came on the display, as well as a warning saying “Brake Malfunction: pull over car immediately.” The traction control light, ABS light, warning light, and parking brake light also came on. The computer code was C1391. This controls the brakes and anti-lock brake system. This is a serious and known safety issue. It is well-documented online, and in 2019 Toyota acknowledged this widespread issue with a Customer Support Program ZKC. However, this program only applied for a limited time, and since then more vehicles have had this same issue with faulty parts. Even vehicles under 150,000 miles no longer qualify for free replacement despite this being a known and widespread issue.
My issue is not that I got a brake warning light (see attached image). My issue is that Toyota knows that this is an issue and will only fix it if you experience the issue before 12/30/2020 or at less than 150,000 miles. It is irresponsible of Toyota to know this is an issue, especially regarding the vehicle brakes (see screenshots of the letter from Toyota).
Driving down the highway the abs srs air bag lights and the warning triangle all came on and then shortly after that a loud continuous beeping sound started and when my wife tried to pull over she realized she really had to cram on the brakes to get the car to stop... this scared the daylights out of my wife and thank god we didn't get in wreck!! But I dont understand why this is not a recall problem after all the other people I have read about with the same problem with the abs accumulator bleeding off pressure causing the pump motor to run abnormally long and in our case constantly to the point of no being burnt up and needing to replace.. my wife is the second owner of this car and we have had it since 2015... how is the window switch MORE OF AA CONCERN THAN FAULTY ABS ACCUMULATORS???
Driving when multiple lights related to traction, ABS system illuminated. Warning message to pull over immediately. Power brakes gone. Had to push brake pedal hard and long to floor to get minimal manual brakes to take effect. High pitched alarm sound. Almost ran into other cars in parking lot.
What component or system failed or malfunctioned, and is it available for inspection upon request? The actuator assembly, and brake booster pump assembly w/ accumulator have failed. Part # 04008-26448 and 04008-51148 How was your safety or the safety of others put at risk? This controls the brakes and anti-lock brake system. Stopping distance and anti-lock performance has been very erratic. Brake pedal feel has been soft or overly-firm and could easily cause a collision or serious accident. This is a serious and known safety issue and should result in a vehicle recall. Has the problem been reproduced or confirmed by a dealer or independent service center? This problem was confirmed by Norm Reeves Toyota San Diego on 3/12/22, and has been acknowledged by Toyota in Bulletin POL 19-06. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There are many warning lamps on in the car, including an ABS and Brake System warning on the display, the traction control light, ABS light, warning light, and parking brake light. The vehicles brake booster has been running frequently and making a loud noise for about 18 months or 2 years prior to failure and prior to warning lights coming on.
