Service brakes

4 reports2 crashes
“Vehicle: 2014 Lexus RX 450h Component: ABS / Brake Actuator System I am submitting this complaint regarding a safety-related brake system defect in my 2014 Lexus RX 450h. The vehicle experienced ABS/brake actuator failure consistent with a known defect that was previously addressed by Lexus/Toyota through a Customer Support Program (extended coverage program, not a recall). I was never notified of this program. I have confirmed that Lexus mailed notification to an incorrect address (Temple City), despite the fact that my vehicle registration address has never changed and has always been accurately maintained with the DMV. As a result, I was deprived of the opportunity to repair a known safety-related defect within the coverage period. Key facts: - Brake/ABS actuator system failure occurred at approximately 150,000 miles - Lexus had previously issued a Customer Support Program for this known defect - No notification was received by me during the coverage period - Lexus confirmed notices were sent to an incorrect address - My DMV registration address has remained unchanged I raised this issue directly with Lexus Customer Assistance, including escalation to a…”

Structure

4 reports1 crash
“My front passenger door actuator has failed. This door cannot be locked/unlocked with the remote or by pressing any lock/unlock button. This prevents the driver from being able to lock all the doors or the front passenger from being able to quickly exit the cabin unless the manual unlock switch is known and applied. This is the 5th door actuator that has failed on this vehicle. I'm the original owner and it has 51K miles on it. All 4 doors failed and this is the second time for this particular door since it was replaced some 4 years & 21K miles ago. The problem started a few months ago and is currently intermittent. Being "sometimes" safe is not being safe. I have not had it analyzed at the dealer since I would not bring it there unless I planned to have it fixed. There were no warning signs or lights.”
