I've been playing with the CRecorder and have found it to have issues w/ the following vehicles. Please add to the list and, if possible, test it (replicate it) on another vehicle (same year, make and model) to make sure it is truly an issue.

Year Make/Model Issues
02 Mitsubishi Eclipse Activates all lights on the dash
99 Toyota 4Runner Activated Traction Control Light (wouldn't come off until cleared with scanner)
02-04 GMC Yukons/ Chev Tahoes Drains battery if left plugged overnight (5 amp draw)
04 Pontiac Grand Prix Did not record anything

Hi!
As far as I remember, the first firmware couldn't work on CAN systems.
When we tried to plug the CRec to the FIAT G.Punto, the situation was the same (Eclipse). All lights on the dashboard
started to blinking. But now we tried a newer one, and it worked without problem.
