Purchased 2014 Cruze in January 2015 and notice occasional sharp bumping sound when going over over bumps/pot holes. I asked if this could be checked when car in for unrelated warranty issue. Jounce bumper replacement under warranty was advised and appointment set as soon as parts came in. Brought car in at 1:00 pm and was called by service rep later in afternoon indicating that because alignment was also necessary car would have to be kept over night. Called early next morning - car was ready. Courteous and informative contact throughout. No indication of noise upon return of car.
