I have a 2006 dts and have for the second time had a problem with getting it started. The first time it happened I turned the ignition to crank it and all my dashboard warning lights came on and stayed on (traction control, check engine, abs) and car would not attempt to crank. I also noticed gear indication light was not on and I couldnt move the gear shift at all. I also notice fuel gage wasn't working either. I knew it wasn't the battery cause everything was working as far as power. I troubleshot for 3 days by disconnecting battery for 30min ,checking fuse and relays etc. I thought water may have gotten somewhere or something . Well I got it towed after 4 days of trying to get it to crank. I tried cranking it before we put it on the wrecker , nothing happened. They got it to the a little shop around the corner and tried cranking it and cranked right up on the first try and every try after that. The mechanic said he couldn't fix what wasn't broke. I left it there an extra day to see if it would crank and it did. They ran a diagnostic on it and there were no current codes but a previous history of no communications ECM and I think TCM. I drove it for 2months no problem but now yesterday it doing the same thing.
CAN SOMEONE PLEASE POINT ME IN THE RIGHT DIRECTION!
