We own a 2006 Highlander Hybrid. Just a few weeks ago the entire ABS system failed - defective ABS accuator which is the electronic equipment for ABS system. Was driving 50+/- mph when all the gauge lights and alarms came on. Upon braking the pedal went completely soft and I had to pump the brakes 3-5 times to get the vehicle to slow enough to turn into a parking lot. We spent 1-2 weeks trying to get Toyota to pay for the part replacement since it is a part generally accepted to last the life of the car (ours 4 years, 54,000+/- miles) Finally got Toyota to agree to pay for half, still waiting for check. Reported the failure to National Highway Transportation Safety Administration to try and get a recall on this part. Not sure if this is the same reason other Highlander owners have been experiencing problems but symptoms leading up to part failure sound very similar. My suggestion is for EVERYONE to file a report with the NHTSA. You can go online and submit a claim in 10 minutes (nhtsa.gov then click on "report vehicle or child seat defect" in blue box in upper right corner). My husband and I spoke to Toyota costumer service 4 times total and were told "there is no defect" for this particular part and that the service bulletin issued by Toyota for the ABS accuator symptoms only aids dealers in correcting the problem but does not imply there is a defect. We found out from an independent Toytoa service provider that the recommended service for the accuator only resolves the symptoms temporarily with replacement of the accuator eventually required. Please, even if you no longer own your Highlander, please file a complaint. Based on our experience and the efforts we made to contact someone of authority at Toyota corporation we've discovered Toyota sets every possible road block to prevent the vehicle owner from reaching the corporate executives. It was only through our Toyota dealership owner that we were "told" to expect a refund for half of our costs. Despite asking customer service and numerous representatives at the Toyota dealership we were repeatedly told we could not be given contact information for the area representatives and their management who ultimately have the authority to resolve our problem. Most people don't have the time, or resolve, I have to make a case out of an auto repair. By filing a complaint, hopefully a recall will occur so others won't have to!
