Have a 2012 CRV and the AWD light on the dash has started coming on. Will start driving and after a few miles the light will come on. I got one of those code readers but even when the light is on it doesn't throw a code on the reader. I have down loaded both service bulletins that deal with the AWD light. Car has just under 24000 miles and still have coverage under warranty. Any suggestions? Will be calling the local dealer to schedule a service.
