Have an 07 Cobalt. I get front end vibration, that seem to come from the driver's side front when going straight on some roads and also when I brake. If I turn the wheel just a little bit the vibration disappears. I just got new rims and tires put on. Thanks!
If the rotor is warped, then even a slight amount of brake pressure will feel like a vibration coming from the wheel. You may also want to make sure the tires are balanced, the shop should have done that but a weight may have fallen off. That type of vibration would be consistent though, and not dependent on the brakes being used.
Sound like an alignment issue. Had the same problem with a jeep before
