2008 TOYOTA HIGHLANDER HYBRID with 138000. miles

I was driving straight on a city street at 40 mph when the vehicle stability control and check brake system warnings alerted, as well as the cabin alarm. At that time i pulled into a gas station and realized the brakes had gone soft and were not functioning properly. I turned off and restarted the car; the problem persisted. I cautiously drove a half mile to my house and connected my vehicle to a diagnostic tool. The codes indicated C1252-7 (brake booster pump motor), C1256-7 (low pressure accumulator), and C1345-7 (linear solenoid valve offset learning undone). The combination of codes points to the brake actuator and pump needing to be replaced. The brake pads, speed sensors, wheel bearings, and relays are all good. After much online research i discovered that brake actuator/pump failure is a common complaint on this vehicle and costs thousands to repair. 2006-2007 brake actuators are already recalled, as well as 07-11 camry hybrid and prius which use the same platform. I contacted a local Toyota dealership who offered no help. The part itself is $1800+ without factoring in labor. I am also troubled by the safety factor this malfunction presents, especially we're it to occur at a higher speed.

2007 TOYOTA HIGHLANDER HYBRID with 124180. miles

I took my car in for a flat tire repair and an alignment. After the services were performed the mechanic was unable to reset the computer as it kept showing an error. All lights on the dashboard were lighted. I drove the car to a Toyota service center. When driving i noticed that the brakes did not feel quite right. It didn't feel like they would brake quickly if need be. The ultimate diagnosis was the car had a C1345 linear valve offset undone and C1368 linear valve offset malfunction. A new brake actuator was installed at a cost of $3200. Per my research, this has been reported for the Toyota camry hybrid as an issue. Perhaps the highlander should also be looked into.

2007 TOYOTA CAMRY HYBRID with 111300. miles

The brake light illuminated on my dash as i was sitting in stop and go traffic. About 10 minutes later, i was traveling about 55 mph and attempted to push my brakes to stop for a stop light. The brakes did not respond normally and it took about 4 times as long to get the car to stop compared to normal responsiveness. Simultaneously, my entire dash board lit up with warning lights. I proceeded to pull over to a safe place, going maybe 10mph, i went to park and rolled into the curb in front of my car because i could not get the brakes to stop the car. I placed the car in park. All indicator lights cleared and brakes started working again. I had the car towed to a Toyota certified mechanic, who told me that nothing had registered in the computer. The car was then driven a bit to try to recreate the problem and towed to a Toyota dealer. Eventually the C1345 and C1468 codes appeared. Toyota was contacted and recommended the accumulator assembly be replaced, brake system bleed, reset memory and calibrated linear valve. Expensive repair was completed and the car is now driving again.

2006 TOYOTA HIGHLANDER HYBRID with 180000. miles

Warranty enhancement letter zg1 brakes failed to engage for the owner and a third-party mechanic. Mechanic suggested it was the abs system and recommended to take it to the dealership. I was told of the warranty letter zg1; mechanic at dealership read codes (C1345 and C1368). They attempted a re-calibration but was unsuccessful. The recommendation was to replace the actuator. Toyota corporate was contacted to see if this would fall under the warranty for replacement. They declined replacement because none of the following codes were noted (C1391, C1252, C1253, C1256). The warranty verbiage does not state these codes must be indicated, but instead says they "may be illuminated". My argument is that if there is a known problem with the actuator, regardless of which codes were illuminated, then this component should be replaced by Toyota. At this point, i have not been told if it is safe to operate my highlander and depend on the braking system or not.
