On april 2 2015 i experienced "reduced engine power" while taking my daughter to urgent care. the vehicle has had over $2000 work with many different repairmen involved. gm advised they were sorry but no recalls - nothing they would do to help. numerous times, we have come close to being involved in an accident when it occurs. we will be driving at normal highway speed, hear a bing and see reduced engine power flash on display. vehicle will immediately go from original speed to no more than 30-40 mph - no warning. it is unsafe to be on a busy road as anyone could rear end us, killing my family
