When trying to drive my wife's vehicle the gauges for speed, tachometer, vehicle status etc turn off. the two touch screens also turn off so cannot control any climate, radio, drive settings etc. it will come on intermittently and turn back off without warning. the car still operates but without any instrumentation. unknown how this affects safety features such as airbags.when my wife drives it is less intermittent but happens from time to time. if i attempt to start the car sometimes it won't even turn on but after a couple minutes i can get it to start. it is push button. have tried both set of keys.
