NHTSA complaint #11388931, filed 2021-01, 54,000 miles“My 2018 SOUL has an automatic transmission and from early on after I bought it new last year 08/30/2018 the transmission started acting up for no apparent reason. What it does comes out of nowhere it will not speed up when you give it the gas. It hesitates for just a brief second then it moves slower than normal. This happens from a dead stop and while driving in traffic too. It will go along driving perfectly for a while then without any reason it will act sluggish and or stumbles. It can happen when it is cold or well warmed up and in all traffic conditions. …”
NHTSA complaint #11229007, filed 2019-07, 5,600 miles“From a stop, the vehicle has a significant hesitation pulling away from a stop sign/redlight etc. As you pushing the gas pedal down, it hesitates then accelerates hard. Has 340 miles on it at this time. Dealer and Kia state this is normal for the new transmission/turbo design. Even the service manager was shocked when he drove it saying he would not have bought it. I would think this problem could be resolved with a programming update. My concern for safety is to part: 1st, anticipating the vehicle may go when in fact it hesitated to pull off creates an anticipation event. …”
