2023 Ford F-150 Hybrid: won't start

Filed Apr 16, 2024 · Brakes, Electrical · KY

While driving on interstate vehicle lost all braking and steering. Numerous warning lights popped up. I almost was in a very bad accident. I was able to put transmission in manual and gear down and finally got steering back with no power and could maneuver off road. Truck then shut down and would not start again. Called Ford and not very helpful. Contacting attorney for help.

The truck initiated a "Stop Safely Now" alert and would not start. I was in a very bad neighborhood at the time and feared for my personal safety. I had to get out of the vehicle, walk away for 10 minutes where the key fob wasn't in contact with the truck, then tried 3 times to start the vehicle without success. I waited another 45 minutes outside in a dark and dangerous area before I finally was able to get the vehicle to start. This is the 4th time since purchasing the vehicle in May 2023 that this has happened. I've had it back to the dealer 3x to troubleshoot but they can find nothing, they've told me that it is a known issue at Ford but they have not received a fix yet. Ford owner forums provided guidance to "let it sit and then try again 10 minutes later". This didn't work in my event and again, my personal safety was at risk.

Sporadically the vehicle will not start. 200 miles on the 2023 powerboost and this has happened 3 times. Vehicle says pull over safely now and will not allow me to put into gear. picture of battery on dash. Vehicle always sitting in heated insulated garage. Waited a day and then it starts. Ford mechanic does not see anything wrong and cannot duplicate the issue so no fix is available.

Truck did not start and kept flashing 2 errors back and forth: "Full Accessory Power Active" and "Stop Safety Now"

I purchased the truck 2 weeks ago brand new and it has a total of 570 miles on it. After not being used for one day, the truck would not start at all. I receive a warning indicating that I should stop safely now, that full power accessory mode is on and a check engine light. I connected a OBD scanner but no codes were generated. The truck should no signs of a dead battery as all electrical functioned other than starting the hybrid electric engine. I contacted a dealership who informed me that I had to have the vehicle towed to them at my expense. I tried multiple times to start the truck again with the same results. While waiting for the tow truck (40 minutes later), I tried again and the vehicle started. There appear to be many claims of this same behavior related to the Ford powerboost engine for several years which I was unaware of prior to purchase. This level of insecurity should have no place when purchasing a brand new $80K automobile as my 13 year old daughter was left stranded as a result.

At times will go out to start truck after it has been running for a while and will not start. Push start button and will not do anything. I had to wait for a least 2 hours before it would start again. I have read on internet that this has happened to several people. It could be very dangerous at night if this happened in some places. This problem doesn't happen very often but does happen. The truck acts like a dead battery this is the Power Boost model. I was told per dealer let it sit for a while and should start.

After vehicle is parked and locked, return to vehicle to start the vehicle and when start button is pushed get a 'stop safely' message and vehicle will not start. Has happened on 4 occasions, disconnect battery, reconnect, lock and unlock - wait and try again seems to be only repair. Dealer has no idea what problem is since he can't recreate the problem.

On 5/10/2023, at around 2 PM, when trying to start my truck after turning off in parking for about 2 hours. The truck won't be able to start with the "Stop Safely Now" warning. Tried all sorts of methods, jumping cable, jump pack, etc, it won't start. After calling Ford Road Side Assisstant, the mechenic was able to jump start it. On 5/24/2023, the truck won't start with the "Stop Safely Now" warning. This time, was able to start it after a few minutes of trying to start it remotely with Fordpass app. Took truck to the dealer, and the dealer had no idea how to fix the issue, which can happen randomly.

My truck is less than 1 month old and less than 1,000 miles. On two separate occasions, when attempting to start the ignition the engine will not start. A "Stop Safely Now" message appears on the dashboard, and the truck will power on the accessories only. Now matter how many attempts to turn on the ignition, the truck will not turn on. This leaves you completely stranded wherever you are. You do not know when this SSN message will occur, and can be a serious safety issue if being left stranded somewhere. There were no messages, codes, or other issues reported from the truck prior to this. The battery was checked and is sufficient. This is a problem with the powerboost hybrid engine in the Ford F150.

I am consistently getting an error message to stop safely now and the vehicle will not start. It is a known issue with Ford and they have promised a fix later this year. The vehicle has left my family stranded for hours at a time, with one instance in a medical emergency.

When I tried to start the truck, the dash showed messages saying “stop safely now” and “ full accessory mode” but would not start. Truck also enters deep sleep mode daily even with a long commute to charge battery. I got the truck started via the Ford Pass app.
