Off and on vehicle locks into anti theft mode. . . . . . Sat overnite at walmart. . Sat overnite at groc store. . . Went to dealer 300 later not fixed they may try this or that $$$$$$$$$$$ each visit is expensive. . . . . Called customer support at gm they told me they new nothing about this happening. . . . . Googled internet a lot of people are dealing with this. . . . Called customer service back they told me not to google internet because many vehicles can break down they do not last forever. . . . . In the meantime I should return to service because they only hire top notch techs who can fix the problem. . . . . They are not fixing it they are guessing and each time they guess the problem exits but my wallet shrinks. . . . . . . . . This passlock even has it's own facebook page. . . . . . . This is bad and dangerous and expensive. . . . The only solution is to buy a kit and then try to find someone to install to override the system. . . . . . . . . This is ridiculous tired of looking at service seatbelt. . Little car with lock on it and turning key to nothing happening all because passlock failure.
