Vehicle was taken in begore warranty expired for losing power and shutting down on road went to san tan ford they said it was a month out come back. I said this is a safety issue and got it in for service in scottsdale while still under warranty like 50k. They said nothing was wrong with it did something because it didnt stop on road until sat [XXX] white smoke started pouring out back and i was able to start it and get it into a parking lot. I called to get it towed they said that my powertrain warranty expires at 60k and im at 63k. Had it towed to san tan ford to see what the problem was and they stated the engine is no good. I need a new engine. I owe 33k purchased it new in october 2021. San tan ford is reaching out to ford to see what it will cover but they said probably only 50%. This is crazy that i have to purchase a new engine when ford was aware of these issues that placed me un danger. What can I do? Please help.

Slowing down at a red light, getting into a left hand turning lane there was a "thud" sound and then the car completely shut off. Nothing worked, screens went blank, no hazards, no lights. We were stuck in the middle of the road with no way to even get the car out of the way. Every once in a while the green would come on or an alarm would go off but quickly went back to black. Tow truck was able to jump it to get it on the truck but half way through the ride the engine died once more. There was no warning at all. If this would have happened on the highway, it would have been catastrophic. After learning about this happening to others and hearing that it may happen again, I will not feel safe in this car moving forward: car is a 2021 Bronco Sport, 52,000 miles. Please do something!!!

Vehicle experienced catastrophic power failure while I was driving. Without warning, the vehicle shut down completely. The engine stopped, the brakes engaged, the dash went black. There was no way to communicate with the vehicle -- no way to engage emergency flashers or even to push it to the side of the road (because the brakes were locked). There was a loud "pulse" sound coming through the speakers -- "thump...thump...thump..." which continued for 5 - 10 minutes. A police officer who stopped to assist noted the rear tail lights were strobing. The "P" on the transmission shifter flashed continually. Over the next 30 minutes, the infotainment screen rebooted twice, but went to black within seconds. The instrument panel rebooted once, but also went black after a few seconds. The car was towed to Kings Ford in Mason/Deerfield Township OH. The service tech reported the only issue was a dead battery which he replaced. That issue has not reoccurred in my Bronco Sport. On the Bronco Sport Forum, [XXX] reported an identical event in Feb. 2023 happened to her vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle started missing at 30-40mph. No lights were on but I took it to the dealership and they determined a new transmission was needed at a cost of $6464.33 plus tax. They indicated it was a known issue but no recall had been issued so I was responsible for the cost. I checked around at other transmission shops and they also said they had been seeing those issues. I looked online and online forums don-??t even recommend OEM parts because they will fail.

I was on my way to work and as I approached a 4-way intersection, the auto-stop feature on the vehicle shut the engine off. The vehicle's instrument panel started blinking then went completely black. The vehicle became completely disabled... the hazard lights were only functioning intermittently. I tried to re-start the vehicle without success and was not able to shift to neutral. The vehicle was in the middle of the road, so I called a tow to carry it to the dealership. The dealership was able to replicate the issue and blamed it on a 'dead-cell' battery. The dealership even said that the vehicle did the same thing to them once their booster pack was removed, so a simple jump from another vehicle would not have temporarily solved the issue. Before the incident, the vehicle gave absolutely NO warning or indication that the battery levels were low. I cannot believe that with all of the modern vehicle technology available, Ford did not develop a 'low-battery' warning light for their vehicles. I expect Ford to pay for every tow needed in the future due to a dead battery that completely disables the vehicle in the middle of the street.

My 2021 Bronco failed our family on Friday. The Bronco failed to start upon pressing the start and brake pedal. The main console panel started flashing then cycling through all kinds of failure alerts. There was a series loud noises from the engine, the headlights flashed off and on for over 3 minutes and then the engine started smoking. The doors would not open and we were stuck inside while the engine was smoking. That smoke came through the air vents as well. Finally, I was able to get my door open though couldn-??t open my son-??s rear passenger side door from the outside. He was stuck inside for what seemed like forever. He was able to open it finally and I carried him inside. My son-??s legs are paralyzed and he does not walk. My main concern was getting him to a safe place as I was scared to death that the engine was going to explode in that moment. The engine smoke started to ease up however the electrical burning smell was overwhelming. This all took place in my garage. The trunk would not unlock and my key fob would not engage with the vehicle at all during this time. The trunk hatch lock finally disengaged and I was finally able to get his wheelchair out. Everything failed. I could not get the Bronco into neutral at any point. The Bronco is currently at my local Ford dealer where I was told I have to wait a week before it can even be looked at. I was told "it's just the battery...." There is NO way my experience was "just the battery." As of 10/10/2023 no one from corporate or the dealer has reached out to me. Once I got to the dealer (Jarret Gordon Ford Davenport), they were so dismissive of me. The service advisor never even asked if my son or myself were OK.

Bought 2021 bronco sport in Dec 21. Since my engine has stuttered and started to die. The panel starts falling as if it is sitting off. This is not the auto engine shut off while idling at a light issue. Upon starting the engine you can hear a ticking and on every certain revelation the vehicle will sputter and start to cut off. It has died on 2 occasions in my driveway, but not yet on the road. It will stutter and start to die almost always in idle, especially in park, but it will do it and stay losing power mainly while driving low speeds or when not pressing gas pedal. I received recall and was told part was not available and didn't know when it would be available and have never been told part was available, but miraculously my recall order was closed without parts ever being replaced. This is like mist of the 8 recalls on this vehicle. 6 recalls where made before the vehicle came off of the train car. 6 recalls were still active the night I drove off the lot AFTER SERVICE WAS CLOSED. My first service was flat spots in my tires from sitting in a train car in Florida heat for 3 months, no parts were replaced, feb and March of last year the recall was closed before my car was in the shop... My dealership is clearing recalls and not reels my vehicle. They are taking advantage of my mental disabilities.

When trying to start the vehicle, it would not crank. Instead, all dash indicator lights, interior lights, and exterior lights began flashing. Numerous random error messages began flashing on the dashboard screen. Then a large plume of smoke began coming out from under the hood and there was an acrid burning smell. No flames were visible so the fire department would not respond when called and advised to have it towed. After much difficulty loading onto a tow truck (the parking brake would not disengage--dash indicated a parking brake fault as one of the many errors--so it had to be dragged onto the flatbed tow truck) the vehicle was towed to the local dealership in Dothan, AL. Per the dealership, there was an underhood fire involving the starter and battery. We are unable to inspect the damaged components. They stated they are unable to remedy the smoke smell that has permeated the vehicle despite the disabling lung conditions of one of our family members. We have tried numerous times over the last 9 months to get the dealership to perform service required by NHTSA Recall # 22V859, but they keep stating the parts are unavailable. They will not say whether this underhood fire is directly related to the recall already in effect.

I currently am at 14,000 miles on my2021 Bronco Sport. I have had no issues prior to what happened to me on August 9th. While I was at a light my car went completely black with no warning and I was not able to put on hazard lights or put it in neutral to get off the busy highway. I had to call 911 as cars were zipping up close to mine and I was only able to wave my arms to get them to see my car was unoccupied. I was screamed at, honked at all while frantic trying to explain to the 911 operator that I needed a deputy to come and put his lights on behind my car to prevent an accident. My car sat in the middle of the highway with no warning lights on until a tow truck arrived. We then found out there is a way to release the gear and put it into neutral so we could push it to the side of the road. The car was towed to the house where I then had to have another tow truck come get it and tow it to the dealership where i was already waiting for a part. (Differential) At this point it has now been 8 days and i have no updates on what actually happened to my car but in my discovery I have read that this is a more common occurrence than not. Just while waiting in the Enterprise waiting room, waiting for my rental I met a girl with the same exact issue. How many others is this happening to and when will Ford recall this model car before someone is killed? I want answers and want to make sure when they say my car is fixed that it truly is fixed. I am scared to death to drive it now that I even have purchased road flares so I am ready for the next break down, because I truly believe it will happen again.

On 2 occasions, 7/30/23 and 8/13/23, my 2021 Bronco suddenly stopped working with no warning whatsoever. I had no way to put on any Emergency Flashers because there was no power. The same day as the first incident, the car was brought to my local Ford Dealer and they couldn't find any problem. When they inspected it the next morning, it started right up.I had been driving the car for 2 weeks and it happened while I was driving again on 8/13/23. It died the exact same way, with no warning and no way for me to alert other drivers around me. My vehicle is currently at the Ford Service Department and they are trying to find the problem.

I was driving down a city street in Sacramento and the car just suddenly stopped- engine and everything was off. I could not get the car to turn back on. Emergency lights would not come on, it was if the entire electrical system was out. I was in the middle of the road, so needed to put hazards on to warn others and I could not. Cops came to place flares to warn other drivers after 35 minutes. No warning codes or anything to let me know what was happening. Having car towed. 10 minutes before tow truck arrived, vehicle started, so I was able to move it to a safer place. But the car was inoperable for about an hour and a half.
