Please also check out the statistics and reliability analysis of the 2012 Dodge Grand Caravan based on all problems reported for the 2012 Grand Caravan.
When the vehicle is in drive but is stationary, everything will turn off. The electrical system goes down and the engine shuts off. After a brief moment (approximately one to two seconds), the electrical system will come back up and all electronic components come back on, but the clock on the radio is reset to 12:00. At this point, we can put the vehicle in park and restart it. This has occurred several times in the past several weeks. The most recent occurrence was 2017. 07. 07 and it did it twice within fifteen minutes. We do not know for sure what is causing this to occur, but it seems to be connected to the main computer and/or the anti-theft system, as this is a complete system shutdown.
The vehicle will shutdown randomly with no indication as to why and/or will not start randomly due to antitheft being activated. The check engine light is not activated upon vehicle shutdown or failure to start. When the engine shuts off while driving the tachometer will reap about 900 rpm and the only indicator on the dash is a yellow traction control illumination on the dash. There is no check engine light, low oil pressure indication, or low battery indication. After a period of time from a few minutes to several hours the vehicle will restart and run normally. The vehicle may run normally for a few seconds to months at a time until the problem reappears. The problem can occur anytime while driving the vehicle including driving on the highway, intersectioons, parking lots, and expressways. When the vehicle stops running, the steering and braking become very difficult to operate.
