Brake actuator failure
Warning lights and reduced braking capability
Check engine light: On
Brake actuator failures cause warning lights and reduced braking capability in roughly 40% of the sampled complaints, with one owner explicitly calling it 'a well known failure component with these cars and yet no recall has been issued.' A warranty enhancement (16-01) extends coverage through 12/31/2017 or 150,000 miles, but multiple owners report denial after that window closed. Multiple reports describe the actuator failing a second time after an initial replacement.

The dominant problem for this generation is brake actuator failure, causing warning lights and reduced braking capability — roughly 40% of the sampled complaints describe it, with one owner writing that it's 'a well known failure component with these cars and yet no recall has been issued.' A warranty enhancement extends coverage through 12/31/2017 or 150,000 miles, but multiple owners report denial after that window closed. The same brake-actuator defect is documented on the Lexus RX. A separate, related problem: dashboard and door panels deteriorating and creating windshield glare, which is also reported on other Lexus models.
