When using the driver's side front seat belt on my daughter's car on friday, 11/13/2020, the metal belt clip clicks into the buckle with an audible click. this appears to be safely engaged, yet if I tug on the belt, the clip pops out of the buckle. I tried this repeatedly and had the same experience each time. my daughter told me this had been occurring for several weeks. realizing this IS a serious safety hazard that needs to be addressed, I called the gm dealer for help. they told me the buckle assembly IS no longer available to be replaced. I then called gm directly to see about getting this part and to report the seriousness of this safety concern. they created a service request case number 9-6357435144. they in turn directed me back to the dealer I originally called. the dealer's service technician then suggested I get a used belt buckle from a junkyard. I called gm again and they attempted to direct me again back to the original dealer I had called and they connected me to previously. when I told them I needed to have them find this part for me, they simply directed me to another nearby dealer. when speaking to this dealer, they did not have the buckle assembly also, but were able to locate other dealers that had it. it will take a week for this part to arrive. in the meantime, my daughter IS driving in the twin cities without a seat belt as it IS defective. I pray she does not get in an accident as it IS winter in minnesota. please notify other owners of this model car that they may have a similar bad experience and notify gm to take this problem more seriously than they have with me so far. respectfully, glen wolf

I own a 2004 chevy impala 3.8L with approx 179,000 milew.my complaint IS in relation to the passlock III system and the overwhelming amount of "no start" complaints from all the different models of gm car owners across the board with this faulty anti-theft system. I live right smack in the heart of the south in a very small town in tennessee and keep in mind, it IS really hot and humidity IS ridiculous this time of year. I picked up my daughter at a friends house after work, about 5:25 pm last thurday, 9/5/19, and my car died as I'm driving down the road, like the engine jus shut off for no reason at all , I had filled my tank a few days prior and knew that was not the problem. My first thought was to put in neutral before losing much speed and tried to crank several times before hitting my flashers because there were a few cars behind me on a 2 lane road with very little shoulder room to pull over off road. I popped the good to see if I could see or maybe even smell anything that may have caused this problem. I'm making sure my battery cables aren't loose, no fluids leaking or spewing and luckily a state trooper was passing thru and stopped to see if I needed help and turned his lights on so traffic would know there were problems and could slowly go around. To my surprise, after explaining what happened, he said he had this problem before with his daughters car, 2002 impala, and told me to try the 10 minute reset procedure and sure enough, after that 10 minute reset, she fired right home and was able to get home, home had he not come along and already known bout this faulty system prior, my daughter and I would have been stuck for some time on the side of a 2 lane highway in the early september humidity most likely waiting for a tow. Upon researching after, found gm are aware of this problem and should have to fix it, been neglected long enough! Thank you!
