there is a recall for 2018 Malibu LT for ECM software to be reprogrammed because it has become corrupted and it will cause car to go up in RPMS while not accelerating and even stalling. You are an accident waiting to happen. . Just purchased my car new with 46 miles on it and went on two errands totaling less than 200 miles when I couldn't accelerate from a stopped position.
