They seem to be better at dealing with TBird issues anyway. On another note, if you are dealing with Ford dealerships, and there is a Lincoln dealer close by, I would suggest that you switch. Then ask, if you buy a new battery and still have a problem, will they search for the cause? And what are their responsibilities under the new battery warranty if it continues to drain? If not under warranty, I would have a discussion your service people that says, you think there is a drain somewhere that they have not identified it. If still under warranty, I would call the 800 number for service every time and therefore they would eventually replace it to cut their losses. Therefore I believe that Ford is the only place and your best bet for replacement. Since they are not under the hood where there's a lot of air flow, but in the trunk, there has to be a tube that exits to the outside for any gasses that build up. If you've read this thread as well as others, you'll find that many T-Birds including a lot of 2005's had battery issues. Maybe not your problem, but the sort of things one starts to look at. What they found was the hood light didn't go off when the hood was opened then closed. The Ford site seems to only list it but does not provide the detail. They replaced the battery and alternator, and then went to looking for something wrong (since it was warrantied and costing them not me). I recall buying a pickup that the battery would go dead after a few days. I'm suggesting that you insist they fix a problem HE acknowledge exists. Ask the question, 'why just 05's'? Should people that buy an '05 be expected to accept a less reliable car than 02 and 03 buyers? I'm not suggesting your mechanic isn't competent. To suggest it reasonable to expect a battery to be dead after 2weeks is laughable. If we put band-aids on serious problems (what could be more serious than not starting?), instead of insisting problems be fixed, manufacturers and dealers will take the easy road. If there are no TSBs listed for your vehicle, that does not necessarily mean there are none. The source of the information below is the National Highway Transportation Safety Administration (NHTSA), which maintains TSBs for vehicles sold in the United States. If I pay 25,000.00 (and up) for a car, I expect it should be well enough made to start again. The following TSB (s) may apply to your 2016 Ford F-450 Sd. There are no plug receptacles, at least not in the Atlanta airport. For instance, I occasaionally drive to the airport, put my car in airport parking, and don't come back for 2 weeks. In my opinion, the battery tender is not the answer for someone that buys a car to use in the manner one buys cars.
