We have a 2007 Toyota Highlander hybrid limited with approximately 150k miles. In October 2017 we began to experience breaking pulsing and squeaking issues. Upon inspection at precision Toyota of tucson, az, it was determined to be the break actuator. The break actuator failure is a very common problem for Toyota vehicles beginning as early as 2004 and this can be easily searched online. This break failure can result in complete break failure while driving (and reports of this occurring are easily searched online). In 2017, the break actuator replacement was fully covered by the warranty enhancement program, but it was verbally estimated at $2200 to repair at that time. As the owners of this vehicle for since 2009, it was odd that we were never notified of this recall/extended warranty- but just 'fortunate' enough to have ours fail in a timely manner to be fully covered by the extended warranty. In November 2020, our 2007 Toyota hybrid Highlander began demonstrating the same break actuator failure 'symptoms' as in October 2017 (pulsing breaks, reduced response to increased break pressure, squeaking noise when break depressed while parked or driving). This repair/replacement is no longer covered under the warranty enhancement program, even though the 2008- 2010 models of our vehicle had an extension until 12/31/2020. The estimate for this second repair in 3 years is ~$2500-$2800. . . For a widely-known and dangerous break engineering error that Toyota is well aware of and has been for years.
