It should have been under warranty as long as you have less than

36,000 miles and you haven't replaced the stereo with a non-factory unit. take it to the dealer

Most all automobile radios actually have at least two different incoming power feeds. One is the normal power that is switched at the ignition key and is normally off. This lead gets powered only when the key is either in the on or the accessory position. From what you are saying this connection seems to be fine.

The other power feed is the standby power which is always active/on. This feed is used to provide "standby" power to the clock and radio presets so these continue to function when the primary power feed is switched off.

My guess is that you have a problem somewhere in that 2nd feed. If you have a Factory Service Manual, it will tell you the color of that wire and you can measure that it always has 12VDC between it and the radio's ground. Based on the fact that the replacement radio did the same thing and you are not seeing any other symptoms that would suggest your battery voltage dropped below some minimum threshold, the problem has to be either in that feed or the ground connection itself.

I'd suggest you take it back to the dealer and let them troubleshoot it more thoroughly now that you both know it was not the original radio unit. You would need the schematic to determine what components (fuse, relay, etc) and connectors might be at fault here.

Reply at the bottom please.

there could be a wiring issue or you could have got a refurbished stereo and it has the same problem, there is no way to diagnose an electrical issue over the internet.

take it to the dealer if it's under warranty.

unit. You

I hope he takes the "take it to the dealer advice! if he trys to check it himself and screws something up bye bye warranty! if he shorts out the stereo or hits a wrong wire and fries the wiring harness it's BIG money!
