While driving, the mdx shifts into neutral and cannot be shifted out of neutral. this has occurred on the highway multiple times. the information display shows first emissions problem, then transmission problem. acura has a tsb out for this b15-034, but won't apply it until the problem appears. having your vehicle shift into neutral in a high speed environment is extremely dangerous. tsb b15-034 needs to be a recall before their mdx shifts into neutral driving on the highway and they become immobilized and people are killed as a result....updated 09/22/15 *bf
