k5 EX with premium package. 7 1/2 months of ownership. has anybody else noticed a slight knocking sound upon acceleration after each shift. Mine started at about 4000 miles. Took it to dealership and they agreed noise was there and opened a techline case with Kia. Road tested and sent a video to Kia they said they would send a new replacement engine and the dealership installed it at 6000 miles. Drove car home and next day noise was back. Dealership now says that is a normal sound for this engine. Also had a rubbing sound in steering column when turning the steering wheel. Kia sent a new replacement steering column and dealership changed it . Problem solved quiet now. Curious if anybody else has had these issues and their comments about them.
