its a shame from GMC to keep this building makin this vehicles , to many problems ... speakers , airbags , driver and passanger door loocks they don't open ..very disappointed at your products.....no pride on your part.

God forbid this would happen but if I crashed into a pond or some large body of water with passengers we would all die!!!! My door locks must be manually pulled up or down.. Its not just 1 door lock.... its all 4 locks!!!.. At $300 dollars a pop to get fixed!!! This is ridiculous!!! Thank goodness I have an alarm system because someone could easily steal or take whatever they wanted...
