| This is a recurring problem- my vehicle (purchased brand new by me) while cruising on the highway will start to try and cut off while driving. the door locks will pop up and down, the dash gauges power on and off, the headlamps flash on and off, etc... last week the vehicle completely shut down while doing this and i had to coast to the side of the road. this happened three times in 48 hours. | |||

| As to date,december of 2012, there are over 212 complaints to nhtsa about the quality of the 2007 silverado pickup,be it 1/2 ton or any other. why hasn't the above administration done something about the problem? my own problem with my vehicle is on the list of complaints as i have already filed a complaint with nhtsa, but to no avail.the gm manufactures have sold the consumer a bill of goods. from reading the list of complaints it leads one to the conclusion that the consumer has purchased a pile of junk.the quality of the vehicles are based on the quality of parts put into the vehicle when it is put together. the auto companies are getting away with highway robbery, when they purchase low quality parts, passing the problems onto the consumer, and not standing behind their workmanship.we as consumers have a right to be protected from shoddy workmanship,and as i see it,we are not getting our moneys worth. when is the administration going to do something about all of the complaints filed? *tr | |||

| We have a new 2007 chevrolet silverado that has been a problem. when you gave it gas it would shift real hard, we took it to the dealership and the seals in the transmission had to be replaced. the truck was in the shop 2 or 3 days for that. the hard shifting was still there. we continued to drive it. a couple days later my husband was driving the truck, and it stalled on him while driving. we drove it for about a week like that until i called gmac to report to them what was going on with the truck. the women i talked with told me it was a saftey issue and needed to be taken into the dealership.we took it into the dealership everytime the truck would stall while driving and nothing showed up on any dashboard displays. when the dealership had it,they hooked a computer to it and drove it. it did stalled on them, and their computer registered a failure, but it showed no codes. the dealership said they had to contact gm to find out what to do. we needed our truck by friday because of prior plans. we called gmac complaint line on thursday to find out what was going to happen. we talked with the complaint department as well as their saftey deparment explaining everything that was going on and that we needed thetruck. they said there was really nothing they could do, and pretty much told us we could pick thetruck up, knowing it was already noted as unsafe to drive. on friday the dealership put a new computer in it, and my husband picked it up. on saturday my husband and i were driving on i-75 in the passing lane going 75 mph and the truck quit on us. we almost had an accident with a jeep, along with almost going down a hill. i called gmac right away to let them know what happened, along with letting them know that the computer wasn't the problem. this truck was a major safety issue. i've explained my concerns with gmc over the last couple of days, and they didn't want to help us at all.*ak | |||
