2023 FORD F-150 HYBRID Engine Problems

On 7/18/25 I picked up F-150 from being repaired (failed Belt Drive Generator/Starter Tensioner). About 3 hours later I was driving up a long grade at about 5,000 feet when I stopped to check on my cargo (a bicycle). At this point I noticed the cooling fans were running increasingly fast, much faster then they had ever run before. I checked the digital temperature gauge and it showed a normal temperature. I opened the hood and saw there was no coolant in the overflow bottle. I assumed the truck was just a bit low on coolant and I had some (5 liters) water with me so I added that to the overflow bottle. Very little water was visible in the overflow bottle. I replaced the cap, turned off the A/C and immediately headed back to the dealer. At no point did the check engine light come on. At no point did the temperature gauge move from the "normal" area. At no point did any warning message of any time appear on the driver display - unless it occured when I was refilling the overflow bottle. The engine was not operating normally however, the gas engine stayed on at all times and did not cycle on and off as it normally would do (truck is a hybrid). When I arrived at the dealer they attempted to fill the coolant system and said it was completely empty - no sign of the 5 liters of water I put into the system. The cause of the leak was identified as the EGHR system, specifically the plastic coolant inlet port. This failure is discussed in Ford Customer Satisfaction Program 24N04 - attached. This failure should not have occured. But when it DID occur the vehcile should have warned the driver that a serious overheating event was occuring. No MIL was set. No driver warners were made and the temperature gauge remained in the normal range at all times. The ONLY way I because aware of the problem was by noticing the increasing speed of the cooling fans. This could lead to fire, or unexpected engine failure or burns from overheated radiator.

my car sometimes specially when i slow down and make turns it loose power and doesn’t respond to acceleration at all i have to wait 3 to 4 seconds to respond and this happens often a tok my truck to the ford dealership serval times but always they say we didn’t find any problems with your truck and it’s very scary and dangerous if i am crossing a traffic light or a highway or passing another cars and happening there where i am gonna be in problem and more chances to crash

The contact owns a 2023 Ford F-150. The contact stated while driving 45 MPH, the vehicle shut off and the wheels locked up unexpectedly. The check engine warning light was illuminated, with the message “Service Soon” displayed. The contact towed the vehicle to a dealer however, the dealer was unable to determine the cause of the failure, but the battery was replaced. On another occasion, the contact took the vehicle to a different dealer, and the engine block was replaced because it was cracked. The vehicle was not repaired after the most recent failure. The contact stated that the failure was now more frequent and occurred more whenever it rained. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 20.

Mileage: 20

Vehicle lost electrical power to multiple systems- Instrument cluster did not display any information- could not tell the speed of the vehicle, how much fuel was in the vehicle, gauges for coolant, oil, etc. were non-existent, did not have use of turn signals, hazard lights, blind spot indicators, did not have use of wipers, heating/cooling and defrost, could not tell what gear vehicle was in, could not tell what mode the vehicle was in. This made the vehicle extremely dangerous to drive. There have been multiple electrical issues prior to this. All issues have been addressed by Ford dealer and supposedly fixed as of now.

The contact owns a 2023 Ford F-150. The contact stated while driving 35 MPH, making a right turn and coming to a stop, the check engine and Forward Collision Avoidance warning light were deactivated, and the traction control warning light and other system failure warning lights were illuminated. The contact attempted to depress the brake pedal; however, the brakes failed to respond as needed. The contact coasted down the street and drifted and parked the vehicle. The contact attempted to accelerate; however, after depressing the brake pedal, the vehicle failed to stop as needed. The contact drifted and stopped and turned off the vehicle. The vehicle was towed to the dealer who diagnosed that the electronic brake booster had failed and needed to be replaced. The dealer contacted the manufacturer and opened a case. The vehicle was repaired. The manufacturer was informed of the failure and a case was opened. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 22,075.

My truck jumps/lurches forward after coming to a complete stop, despite the brake pedal being applied. It almost feels like I’m being rear ended. Very scary at first. It happens a few seconds after I come to a complete stop, and every time I stop. Doesn’t happen if I don’t come to a full stop.

On numerous occasions the truck fails to accelerate and bogs down when taking off and turning at the same time. This has occurred when pulling out of a parking lot onto a busy street where cars are going the speed limit of 45 mph. When pulling out and making a turn you push the gas and nothing happens. The truck is basically coasting from the initial take off and is going less than 20 mph. Suddenly the cars that were coming down the road are right on top of you swerving and hitting there horn because they think you deliberately pulled out at the last minute in front of them. In actuality you pulled out of the parking lot with ample space. The problem is the truck did not accelerate. Secondly the truck handles terribly when pulling out of a driveway that has multiple angles. The truck can violently toss riders around in the seat at low speeds. This could cause someone to lose control of the steering wheel. I have reported these problems to ford dealer. I have either been told there is no problem or told “we found the problem and fixed it” only to experience the same dangerous faults time and time again. I have gone as far as telling the dealer to put in their records that I said “someone was going to get killed in a car wreck because of these flaws.”

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.

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.

Truck wouldn’t start (2000 miles). Dashboard had a “stop safety now” warning light as well as the check engine and battery lights on. All other electronics seemed to be working normally. After sitting all night, truck started normally and drove normally.

Mileage: 2,000

1. My 2023 Ford F-150 Powerboost Hybrid is receiving the Stop Safely Now message. The vehicle has failed to start on a few occasions. 2. The vehicle not starting left me in a position where the vehicle was inoperable. This is a safety concern because is would put me or my family in potential danger from the elements, inability to receive health care and potential danger from individuals of I’ll intent. 3. Yes. 4. Unknown. 5. Unknown. Although I received low voltage messages, I had no idea what that meant. The Ford app simply told me to drive the vehicle to charge the battery. I drive the truck daily.

Got into my truck after work and it would not start. Two warnings were flashing "Full Accessory Power Active" and "Stop Safety Now". I turned off my truck, the tried to start it several times. 15-20mins later, my truck happened to start.

Can’t the start the truck, it shows “stop safety”

My F150 was purchased new and I have had it about 3 weeks. It has 1400 miles on it. Sunday afternoon April 30 2023 I could not start my f 150. There was a warning STOP SAFELY NOW and the car would not activate the engine, or disengage the parking brake. I turned everything off and waited a few minutes then tried to activate my f150 again. Again the car was bricked. The next morning May 1 at 8 am the car functioned and normally. I contacted a Ford dealer and was advised to make a service appointment. I did and took the F 150 in for service May 2 2023. It is now at a dealership for diagnostics. Had I been at 70 mph on teh interstate with a warning like STOP SAFELY NOW and then been stranded that could have been very hazardous.
