Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“This is the third Lexus I have had that the automatic door locks don't work. All 4 actuators are bad after I even had one replaced. I have had this happen I all three Lexus' that I have owned. I have talked to Lexus about this and the service people say that they see more than they should go. Bad boy. Lexus/toyota does not think it's a problem. This becomes a safety hazard locking the doors manually and having to open one door with a key and reach around and open the others as needed. Specially with all the crime around us. …”
