Vehicle is not holding ev now/later modes causing unexpected battery usage and fuel consumption. An example is traveling highway speeds (70-75 mph); vehicle will unexpectedly switch into auto mode and revert from gas/hybrid performance to electric/battery only performance which is reduced power and response again at highway speeds. This is not always the case as I have found this to happen before I enter the highway and can adjust my drive accordingly. Additionally, this happens in ev now mode which holds the electric engine to prevent gas use at all but the system will inadvertently switch to the auto mode. Condition is extremely sporadic and difficult to replicate most times will happen without throwing a check engine light code. Fortunately I do have a few instances where a code was thrown and I was able to have the dealer take a look and make some warranty repairs none of which have resolved the issue as it still comes back in the same random form. Attached are the several dealer visits to address the concern and after several visits, the transmission pump module seems to be a repeat issue. Unfortunately not sure if this is the cause of the modes not holding as it should.

Driving my 2015 Ford C-max and all of a sudden I lose power. I press the gas and nothing. I was driving through a intersection and had to coast to the side of the rode. Big red triangle show up saying "stop safely now". car has been at the dealer for 4 days, they are trying to find the problem. I have read online about this problem with multiple Ford vehicles and a recall was called for the Focus. I guess Ford is to big to go after and the ntsb drags there feet like no other. Call for a recall on all vehicles that "stop safely now'. will you wait until people die to do something!!

1. on taking a trip from panama city beach, fl to indianapolis, in this cmax was parked & locked in the northwest Florida beaches parking lot at approximately 9 am cst 2. at approximately 4:30 pm est a telephone call was received from the airport police informing me that the cmax was in the parking lot running with the lights on and I was asked to go to the parking lot and turn the automobile off. After I informed the officer that I was in Indiana and could not comply with the request, I proceeded to make numerous telephone calls; Ford Motor Company, gary smith Ford and others in an attempt to have the cmax turned off but was told it could not be done. I then returned officer's call and asked that they go to the parking lot, break the drivers window, and press the start/stop button to turn the cmax off. The officer called me back to inform me that when they went to the lot, the cmax was not running and the lights were off. 3. upon returning to the airport on 2/8 I had to use the key to access the cmax since the battery was dead and the gas tank was empty. 4. a jumper battery was used and fuel was added to enable the cmax to run. 5. this vehicle has numerous indicators, audible and visual to alert the driver if exiting the vehicle while the car is in the run mode. The exit from the cmax on 2/2 was normal. Nothing was on. The locking indication was normal and no lights were on ( I keep the headlight switch in the position where if the vehicle is in the run mode, the lights are on ). this problem had to have been caused by a signal from an aircraft or a radio, radar with enough power to broadcast some distance. 6. my concern is that if this type ignition system can be turned on accidentally, it could also be turned off accidentally and that could be disastrous if the vehicle turned off while in motion causing the driver to lose control.

Reverse gear setting actually put the car in drive after starting the parked car nd attempting to back out ofparking space. I tried turning off engine, and the same thing occurred, the car continued to creep forward until the car made contact with the parking space sign. This is not a small issue as 1) it probably occurred previously with the same model in the same fleet and leaser charged me upward of five hundred dollars to fix vosmetic damage caused while parallel parking and 2) thus could cause bodily injury had the parking space not been blocked in front. These cars are part of a membership based rental fleet, and should be highly maintained. After contacting the emergency number of the fleet leaser, I was a few minutes later able to reenter and start the car, and the reverse gear operated properly. The leaser has previously raised my insurance rate based on small amounts of damage to a fleet vehicle incurred while parking. My guess is that they know of te problem and have chosen to blame the drivers rather than the manufacturers or maintenance engineers.
