Owner reports
Selected complaints filed with NHTSA by 2010 Toyota Highlander owners, lightly cleaned up (personal details are redacted by NHTSA).
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.
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.
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).
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. …
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. …
While driving several passengers, vehicle brakes failed, dash lights came on. Brake booster pump and actuator failed according to Master Mechanic. Vehicle available for inspection. Brake failure sudden reduction is stopping distance unexpected nearly causing collision to other vehicle and possible injury or death to others. Toyota aware of issue (customer support bulletin (zKc) which expired 12/31/21 without notifying me of issue unless NHTSA call for SAFETY RECALL. Problem is same exact as my 2010 PRIUS which was safety rcalled NHTSA Code 13V235000.without any brake problem indicators. Toyota refuses to repair unless NHTSA calls for a SAFETY RECALL beyond 12/31/21 expired date of (csp bulletin zKc. I experienced what I thought was slight & brief dash light which went back to normal immediately. First appeared Sept 1, 2021.
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???
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.
The brake actuator assembly and brake booster pump assembly had a recall on it but my truck was not having problems then. I noticed that when I start braking, the truck speeds up. Then all the light on the dash board came on. When my vehicle started having problems I call and they told me that the recall had expired 3 months earlier for my vehicle and it was up to the owner to have it fixed. I didn't get a notice and I wasn't aware of such recall so why am I liable for the repairs. I need help with this please.
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
