Extremely scary! Started yesterday, the battery and alternator tested fine. All displays are "normal" and the Service Engine Light is not on.......thoughts?

Thank you!!

Some more specifics and a time frame would be help full? How long does it run, Does the idle drop really low and then the lights dim? how long does it take to stall after the lights dim? When you say hard to start does it take a longer than normal crank time to get the engine started or does it just crank and crank and crank and crank and then kinda start and then crank and crank and then start? Does it idle rough once it does start?

There is a recall on the dash board. There's some kind of short from the factory. Call your dealer, and tell them the dash keeps going out and acting crazy, on and off. They'll replace the dash and that might fix it. It will go out eventually so you might want to get it replaced under the "RECALL" asap before it expires.
