have had a 2015 for 2 weeks, left the house to do errands run fine, stop and got gas, went to Walmart running fine, when backing out stalled, put in neutral started again put in reverse stalled again, finally running but when vehicle slowed down to red light acted like it was going to stall again it did this several times till we got home, every time we slowed down, it acted like it was going to stall.
CEL not on?
