Consumer Description

While driving the vehicle between 30 - 40 mph, the vehicle will intermittently studder. I have mentioned this issue multiple times to the dealership and they have attempted to fix the issue but the problem still continues. The issue is occurring more frequently and I’m concerned this may create additional engine/powertrain problems down the road.
