I recently read that NHTSA.GOV has webpages of Technical Service Bulletins (TSBs) specific to vehicle year, manufacturer, and model. However, I didn't find them easily and emailed the webmaster for help. The reply states: "To look up Technical Service Bulletins (TSBs) which are known as Manufacturer Communications on our website go to NHTSA | National Highway Traffic Safety Administration click on the Recalls tab. Enter your vehicle's Year Make and Model, then click Search. Under the vehicle information, you will see a section for Manufacturer Communications click the Blue number. There you will find the Manufacturer Communications that have been issued for that year, make, and model." There is no search function for finding TSBs that are relevant to a particular vehicle problem on the NHTSA website. Therefore, I created a file which contains a brief description of the subject of each TSB for 2013 Ford CMAXs and the URL of the TSB. It can be searched for keywords by loading the file into any document software that has a search function. The file is attached for those who would care to use it to help diagnose the cause of CMAX problems. (Many of the TSBs were issued for a broad range of model years. (Although the NHTSA website has separate web pages for CMAX Energi models, many of the TSBs in my CMAX file also cover the CMAX Energi model.) In addition to the TSBs, the NHTSA website also provides webpages of complaints from owners about vehicles of specific year, manufacturer, and model. In the case of the 2013 Ford CMAX, a few failure modes were the subject of a large number of complaints. Among these is unexpected discharge of the 12 volt battery, which I have experienced repeatedly, and which a local Ford dealership has been unable to cure, notwithstand billing me hundreds of dollars for trying. Had I all the information available from NHTSA to show them, I suspect that at least I could have avoided paying the dealership for reprogramming all CMAX's module firmware, and perhaps been able to point them is a direction that would have led to success. (My workaround is to carry a voltmeter and 12V SLA "jumpstart" battery in the vehicle which I can use if stranded in a location where I can't plug in my battery charger.) 2013 FORD CMAX Technical Service Bulletin URLs & Brief Descriptions - NHTSA.GOV.txt

Hi. I have a 2014 Energi, 9K miles. I used the 12 volt compressor for about 90 seconds to put some air into a tire with a mysterious slow leak. Unplugged the cord, rewound the cord and cable, opened the door to put it back in the car, and discovered that the fan was running full blast (though the lights for the ventilation system weren't on), and the car was switched on. The fan would not turn off, and the car wouldn't shut down either. I tried a lot - sometimes it seemed to switch off and immediately came on again. The Stop Safely light was on, and a wrench icon was displayed - back and forth. I called my dealer; they said to have it towed in; I got that process started; maybe fifteen minutes later I got the automated call to say the tow truck would be there in 45 minutes, and went out to get something out of the car. It had shut itself off. I started it, and everything seemed normal, except that the Check Engine Soon light was on. I turned the car off, cancelled the tow truck, and drove it five miles or so to the dealer without incident. Haven't heard anything yet.
