The contact owns a 2018 Lexus RX350.

Lexus 2018 Rx450hl is known to have issue with brake actuator. A faulty brake actuator causes the car to fail sudden stop. It’s definitely a safety issue. Lexus have technical service information bulletin(tsib) for this issue since 2019. They never contact the owner to replace the faulty part. So if the car is under warranty they will fix the problem with no cost. But if the warranty pass the threshold, they are charging the costumer 3.5k to replace it. It’s an absolute horrible business practices. This part is a manufactured defect and it’s a safety issue.

The slightly opened sunroof spontaneously exploded with shattered glass flying outward and some glass pieces falling on my husband while he was driving. The vehicle can be inspected; however, a Lexus dealership replaced the sunroof glass without charge, the next day after the incident. The unexpected loud explosion with flying glass startled my husband while he was driving. Fortunately, there were no cars around him at the time, because the fright caused by the explosion could have caused a multi-vehicle accident. A Lexus dealer inspected the sunroof damage, and though they would not acknowledge this was a manufacturer defect, they did replace the glass without charge, stating it was a "one-time goodwill gesture." The day before the repair, the damage was inspected by Senior Officer Sampson of the Maryland Transportation Authority (phone number 410-537-1197) on December 13, 2021 (not long after the incident). There were no warnings or symptoms of any kind that would have alerted the driver to the spontaneous explosion.
