When the car gets to about 40 miles an hour if you are accelerating normally, after the 2nd or 3rd start the car sort of hesitates when you get to that speed and it's kind of scary because I do not want to be in the middle of the road and have the car stall out or have the transmission fail completely in the middle of an intersection.

There is also a really loud and annoying vibration noise coming from the front left wheel that gets louder and louder once you go over 25 miles per hour and that is also scary thinking that the wheel may fall off while I am driving as well.

One more annoying thing is once I go above 10-15 miles per hour, coming from the back of the car a sound that sounds like very loud rattling, it appears the sound is coming from the back wheels and I have been told it is the shocks that make the noise but that is it.

Other than that nothing else to say just hope to fix it so watch out anyone who buys this car brand new.

I purchased my 2008 Chevrolet Cobalt from Vandergriff Chevrolet March 2008. Happy of my very 1st major purchase and my very 1st brand new car!! After 6 months of driving the vehicle, my car starts to give me hesitation and stalling with jumping RPMs. Since then I would go to service at every oil change and report problem. They could never duplicate the problem. A service manager, Mr. Scheroder, even drove around with me and at the time the car didn't stall. Over the course of these 3 years, it took me until this year to THINK!! Just video tape it! i did, and finally... WE SEE THE PROBLEM!! hmmm? now you see it? 1st it was the torque converter.. replaced. Problem is still there, took it back, NOW its the transmission chip or something.. replaced.. problem is still here. I picked my vehicle up today 5/6/2011 and less than 5 mins the problem is still there. I have contacted GM and I get their call center that is obviously no located in the USA then i have been assigned 3 different "district specialist" Kevin, Deongela, and now Victoria.. There was one more that I have yet to speak with about my Power Steering failing on me which caused me to wreck and get hit by an 18 wheeler but that's a whole different topic. I hate talking about b/c I'm still in fear when I drive just thinking about the hit. what if my kids where in the car? Back to vanderfgriff.. Overall, i will never buy from them again. I am the only person in my family that went to Vandergriff and we have 6 GM made vehicles. None but my death trap Cobalt has had issues. Back and forth back and forth. If they worked on my vehicle today.. why was my car so scorching hot on the inside of it? felt like its been sitting outside for the past 3 days it was there. I'm not stupid. I flagged down a local sheriff on my way home, asked his advice and he kindly witnessed the hesitation. I just mailed in my Lemon Law complaint and will make sure I am not going to have to deal with this Car and its issues AGAIN! I have to pay another certified mechanic just to inspect the work Vandergriff supposedly performed for me. ready for this to be over

...and to think, i was made famous by this car back in december 3, 2010.. headline news.. MANSFIELD SUPER MOM DELIVERS BABY IN HER CAR!! When i was on Fox news I wanted to blast GM and Vandergriff so bad but I said no kea.. don't cause trouble. but NOW!! I'm determined. I will win if I don't quit and I'M NOT A QUITTER
