2007 Cobalt, new lower control arm bushings..

My 2007 Cobalt at 31500mi out of the blue started making this horrible front-end clunk over bumps at lower speeds. I suspected maybe stabilizer bar end links having been down that road before with Chevys and Fords?? Nope, they feel tight as new? Jacked it up, got underneath as best I could, couldn't find any play or noises anywhere. Of course this was after accidentally grabbing the catalytic converter and burning the finger prints off several fingers. (scorching hot after 20sec BTW thanks to GM's air injection :!) Anyhoo.. frustrated I called the dealer I bought it from. They set me up with an appointment the next day. Long story short? Per the invoice; The front lower control arm bushings had to be replaced on both sides, plus a front end alignment. All on GMs dime. Even got shuttle rides. No fuss, no muss. Is it common for these things to go from all to nothing in one swoop? The car has always been tight and clunk free?

Getting here bit late on your post but wanted to let you know that I have a 2007 Cobalt LT Sedan, 2.2 - 4 cylinder, bought new Jan. 22, 2007 . Had 15 miles on it (8 of which we put on during test drive) when we pulled off lot. Has been a fairly decent car up until the recall on the power steering motor.

When I took it in for that replacement, I had mentioned that recently there was a small clunk from front end, going over even the smallest of bumps, which seems to be progressing to a bigger clunk in last few weeks, sounds like whole front end going to fall off and asked if they could confirm if the lower front control arms were going bad. (Thanks to forums like this, I didnt look like a total fool and actually acted like I knew what I was talking about ). It took approximately 10 seconds for a guy on the ground looking at each side for them to say, YES they are almost on the ground, and need to be replaced.

Well, I am out of my warranty by 5 months, and the kicker is I only have 13725 miles on car !! So to answer your question, yes these parts can fail at moments notice. I am so upset right now that with mileage like I have, I am already faced with putting money into this car. What can I expect in the next 13k miles to have to replace? I have learned my lesson, and will now make sure to let anyone who wants to listen to not buy a GM vehicle. Our old '01 Impala (bought with 7500 miles on it in 2001) was nothing but a headache, and now same with this vehicle.
