 We purchased a 2008 Highlander Hybrid in 2013.  The car was practically maintenance free until last week.  All service except oil changes have been done by the local Toyota dealer.  My wife was pulling out of the driveway when the ABS/VSC lights came on and the console said to pull over.   A code scan said it was C1391, internal acc pressure leak.  Took it to the dealer.  They said it needed a new brake accumulator and a new brake booster for a total of OVER $5000!   Researching the issue, I found it is a fairly common issue for these cars.  When I called Toyota to ask if the cost of this repair, equal to 1/3 the cost of the vehicle, could be mitigated, I eventually got a woman who told me that since I didn't take the car in to the dealer for nearly a year in 2015, I was not a loyal Toyota customer and they have chosen not to help me.  REALLY!!??  The car didn't NEED any service during that time!   I own 5 other cars including a couple of BMWs and I have NEVER had a repair this expensive and have NEVER been admonished by an automobile company representative for not getting a car serviced when it didn't need it.   This was our first Toyota and will be out last.
