Instead of bitching about it hear to primarily deaf ears you guys should contact the NHTSA and approach it as a safety concern. Essentially it engages erratically and can become detrimental when pulling into traffic ect. If there is a safety concern and there are enough complaints it will warrant an investigation. At that point GM will have to address the issue.
A bunch of potential customers saying they wont buy it means squat vs an investigation and potential recall.
