Good grief! I read this post the other day and today it happened to me. I have an 04. Road it to work this morning and all was fine. Got on it to go to another company and going down the road I had no speedometer or gas gauge. I couldn't remember how much gas I had so I pulled into a station and filled up and then turned the key on and I had everything back.
What timing to read this post just the other day. Now I now!
