Squeaking noise coincides with hesitation in driving. Service technicians cannot figure out what the problem is. Had in to dealer 3 times, once they kept it for 5 days and said they couldn't find the problem. Feels like a jerking or bucking, happens randomly/frequently. Doesn't matter what gear or how fast, happens when applying brakes and applying gas. Buzzing sound in steering column. Said was fixed once, but still occurs.
