2021 FORD BRONCO Engine Problems

Ford has 3 safety recalls on 2021 ford bronco and they have no remedy to fix any of them yet. My car stalled out 3 times now because of the low pressure fuel pump failure recall. I was pulling out into traffic and it stalled out while a car was coming at me. The only solution Ford had was to put old parts in the car which I refused. I asked for a loaner vehicle and they said they don’t have any. Recall warning is going on 6 months. I am at a risk and other people are at a risk having my car on the road, tried lemon law and Ford denied me. Nobody feels safe in my car and someone is going to get seriously hurt if this happens at the wrong time.

Ford has issued a recall (24S55) stating the Intake valves on the ford bronco with engine2.7L and 3.0L will harden and crack or break and loss of power. I had the same issue in my 2021 Ford Bronco with the 2.3L engine while I was driving in the highway I got a check engine light then it started cutting out horribly so I slowed down to pull off the road through a metal gate that was open with a cattle guard and the engine died as I was turning in and loss power steering trying to turn the wheel back in time I didn’t and ended up side swiping the pole and knocking off my side mirror and damaging my front quarter panel along with the front door. No damage to the solid metal pole. But I took my vehicle to the local ford dealership to see what the issue was and at the time they should have gotten the recall and at least put two and two together and let ford know about the issue in the 2.3L also but they didn’t mention anything about the valve being broken but said it had no compression and the spark plug diode was broke off. I’ve never seen a diode and the diodes ground hook break off on its own it’s always been broken off from being hit by something but they said it needed a whole new engine for $13,000 so I took it to another mechanic since that’s always that dealerships go to answer for everything is it needs a new engine so the new mechanic did the same stuff and also used a bore scope but instead of just saying the cylinder was bad he seen the hole in the valve and said it just needs a new head with new valves so since I needed my ride to be able to get to work and for half the price they tore it down and sure enough the valve was cracked with a hole just as they said and just like the recall (24S55) but had that dealership paid attention to safety alerts and ran the issue up with ford and let them know the same issue had happened in the bronco with the 2.3L engines also I wouldn’t be writing this right now. I’d be putting a 5 star review on their page not a 1.

I was notified that there is a safety recall on my vehicle and there is no remedy available. I am concerned because of the issue may cause me to stall and likely crash. This is very concerning . I am not sure why there’s not a remedy. I hope there is soon. Please tell me what can be done as soon as possible.

The contact owns a 2021 Ford Bronco. The contact stated that water was entering the vehicle through the roof. While the vehicle was parked, the vehicle started rolling down the hill. The contact stated that the brake pedal was continuously pumping while being depressed. The contact stated that the brake lights were illuminated. Additionally, the vehicle occasionally failed to start. The vehicle was taken to an independent mechanic who replaced the battery. The vehicle was taken to the local dealer where the battery was replaced. The vehicle was returned to the contact with rust and mold throughout the vehicle. The vehicle was repaired, but the failure recurred. The manufacturer was contacted, who opened a case and discussed a buyback. The failure mileage was approximately 14,000.

Mileage: 14,000

24S55/24V635 When will the recall resolution or test be available? Expected q1 has come and gone.

Ford has failed to remediate NHTSA#24V635 by the end of "first quarter of 2025" as they had promised. No updates have been issued. What are they doing?

When driving on the highway and pressing down on the gas pedal, the bronco immediately stalled without warning. The vehicle gradually slowed down and I was unable to do anything except turn the wheel. I was lucky that there was a shoulder to pull over to. (This time of year there are tons of spots on the highway that there isn't a shoulder to pull over to and could have posed a HUGE safety issue!) Even with the shoulder, large vehicles were driving by at speeds of 80mph with just a few feet of clearance. I was unable to start the vehicle after multiple attempts. Electrical power to the vehicle still worked. I had to call a tow truck and tow us the remaining way to our destination. After several hours (roughly 3 hours) the vehicle was able to start again. I drove to the dealership to have them look at it. They could only tell me that it was a low fuel pressure incident and could not replicate it. They said could just be "bad gas". This same exact incident -vehicle stalling while driving and pressing on the gas pedal, without any warning, has happened two additional times since this major incident. I took it to another dealer to have it looked at again and they said almost the exact same thing. System shows a low fuel pressure event but that they can't replicate it. I believe it could be tied to the NHTSA Action Number PE24019 that is currently under investigation. This is an extremely dangerous issue and wildly unpredictable that could leave me stranded or hit on the side of the road at anytime. Additionally, it's frustrating to see the possible issue under investigation for recall since July 2024 (before any of my issues) and have neither of the two dealerships tell me this information after I specifically asked if there had been any similar incidents reported. I had to do my own research to find this. Please help! Please recall!

Bronco lost power, crank no start, 24 miles from a maintained road. Left us stranded and required 5 Jeeps to recover vehicle to pavement before having it towed to dealer 172 miles away. Extremely dangerous situation to lose power descending a steep hill and leaving vehicle stranded miles off road in 100+ degree weather. Low Fuel pressure DTC captured, possible loss of fuel pump, several similar reports on [XXX] . Currently at dealership for diag and warranty work.

Week and half ago engine started idling real rough, sputtering, then drove about 100 yds. Engine conked out in middle of intersection and would not restart. Was dangerous because had 3 grandchildren in back seat. Because engine wouldn’t start I had trouble trying to get it in neutral to push vehicle to side of road. Had to walk grand kids back to their house. Got a AAA tow approximately 35 miles to Ford dealer where purchased. There were no warning messages prior to engine failure except the rough idle and sputtering Vehicle was diagnosed as a fuel pump failure, but vehicle is still at dealership over 10 days awaiting parts

2.7 engine failure while accelerating on to a hwy. Loss of acceleration and power. I was unable to get fully off the road. Engine was replaced under warranty only 3,636 miles on car. No warning lights prior to this failure. Once engine failed and started smoking the check engine light came on.

Four hours into a drive today, going down a fairly steep hill @ ~30mph into a 4 point intersection my Bronco lost all power, brakes and steering. I mean it had nothing. We barely made it thru the intersection because the cars coming directly at us slammed brakes. I had no control and went off the road into someone’s yard, barely missing their fence. It was the scariest thing we’ve ever encountered. My son in the back screaming STOP at the top of his lungs is burned in my brain. What makes all of this worse is that Ford just had it in the shop for 3 days because the week before when they had my Bronco in the shop for yearly inspection/oil change and under their care it had the first symptoms of this issue. I received an app notice of a battery failure AND at their request because of this new issue they wanted my car for a “longer look” the following week. Today was first time driving it since they handed it back to me (I use the valet service that picks up and drops it back to me). Ford could come back and say they will give us a new car and there’s no way I can ever convince my wife to get back in this car. She was absolutely freaked out as the cars coming towards us would have drilled her door. It took Ford 4 hours to come 17 miles to tow us (probably a contractor) to the local Ford dealer that was closed by the time it arrived. We had to Uber to Enterprise and then drive the rental home four hours.

The contact owns a 2021 Ford Bronco. The contact stated while driving 70 MPH, the vehicle lost motive power and the accelerator pedal became inoperable. The contact pulled over to the side of the roadway. The contact was not able to restart the vehicle. There were several unknown warning lights illuminated. The vehicle was towed to a dealer to be diagnosed. The contact was informed that the failure was due to a faulty fuel pump inside the fuel tank and a faulty fuel module. The vehicle was not repaired. The manufacturer was made aware of the failure and determined that the vehicle was not under recall. The contact was advised to call the NHTSA Hotline for assistance. The failure mileage was approximately 16,900.

Driving on the highway, the check engine light came on. I felt a loss of power in the vehicle, and couldn't accelerate. I was able to pull over put the car in park and turn it off. When I tried to turn it on, there was no power. Had to get it towed to the dealership to replace the engine.

The contact owns a 2021 Ford Bronco. The contact stated that while driving at an undisclosed speed, she depressed the accelerator pedal however, the engine failed to engage, and the vehicle stalled. The vehicle was towed to the contacts residence. No warning lights was illuminated. The vehicle was not diagnosed or repaired. The dealer was notified, and the contact was scheduled and appointment for the following month. The manufacturer was not notified of the failure. The failure mileage was approximately 6,000.

Mileage: 6,000

Check engine light came on and I took it into the dealership. They found the codes and confirmed low compression in cylinder 6. Was told I needed a new engine.

On December 4, 2021, I was accelerating to get on the freeway when my Bronco started shaking (from the front of the vehicle/under the hood) and refused to speed up. I was thankfully able to pull safely off the freeway into a vacant lot and wait for a tow. The work was completed, but I still had to wait over a month before getting my vehicle back. The entire engine needed to be replaced.

I have reported this prior (complaint number 11481579). Another total catastrophic shut down of the vehicle occurred while my son was driving causing a near miss fatal rear ending on a busy road. The vehicle loses all power and electrical for no reason while being driven. Only after 5-10 min can the vehicle be restarted. I am reporting this story to new agency so I recommend the NHTSA take issue seriously.

In November 2021, I received delivery of my new Ford Bronco 4WD Badlands vehicle. I went for a road trip with my family and friends in my new car. While driving back, the car engine light appeared on the dashboard, along with the service alert, and the car began to make noise. I pulled over and tried to restart the car, but it never started. We were in the mountains, where there was no signal for more than ten miles. We were completely stranded, along with my kids, who were 13 and 16 at the time, and one of my friends' 8-year-old daughter. We were fortunate to be with our friends and he was able to take us to a near-safe area where we could contact Ford and the dealership. After 5 hours of waiting in a safe zone, we received a towing truck. I picked up the car with the towing driver and parked it at a nearly Ford dealership. We had to book a hotel room in the area, and the next morning I went to the local Ford dealership to request an appointment to see the problem, but they said they didn't have any appointments available for another three weeks and insisted I call Ford customer service again. Ford customer service arranged for the same towing company that came last night to help haul the car to my dealership, where I purchased this car. My local Towne Ford dealership was nice enough to inspect and repair the car, but after a few days, I had a similar issue and they suggested that they replace the engine with a new one. The dealership took nearly a month to ship and repair the engine replacement. A few weeks ago, as my family and I were driving from SF to LA, my car suddenly lost power. I kept getting the message, "Powertrain Malfunction/Reduced Power fault detected," and later, "Service Engine Soon warning," which states that the engine control system has determined that the turbocharger is producing less boost than normal.It was shocking because I was on vacation with my family in LA, and the kids were terrified to even be in the car. this are some experiences

my car went from 50 mph to nothing. lost power. coasted to the side of the road barely avoiding traffic. dark road, sheriff had to sit behind car so I was not rear ended in pitch dark had to be towed to the dealer. one week later dealer uncertain. likely complete engine failure maybe fuel valve less than one year old. 11,000 miles

While driving approximately 40 mph the engine just shut off and the car stopped without warning on an extremely busy road. I could not turn the car back on at all and had to have someone help me push the Bronco to the side of the road. My Bronco had only about 3,500-4,000 miles on it and is less than a year old. About 5 months earlier I did hear a strange and very faint tapping noise from the engine right around the wheel base when I drove under 35 mph. About a week or two after I noticed this noise, it then went away. When I was at the Ford dealership getting an additional key programmed for my Bronco, I asked if they had heard of such an issue or if they thought it was something they should look into. They thought it was just a new car working out new car sounds.

I was driving about 65mph on a bridge when my engine completely shut down. I barely was able to coast to the end of the bridge and was almost struck by multiple vehicles. This is a new bronco with 3000 miles on it. I see they had problems with this in the 6 cylinder but I have the 4 cylinder and this happened. Also when u got to the side of the road every single warning light in the vehicle went off. There was no warning sign. No previous issue. It just happened out of the blue and I could have been killed because of this. My wife was in the vehicle with me and was terrified. Then it took 4 hrs to get a tow truck to get us using road side assistance. Now I'm out a brand new vehicle for God knows how long and have no transportation.

Engine failed and replaced under warranty.

Very rough idle, rpm’s bounce and do not stay smooth at all. Have 10,000 miles, has run rough since purchase. Getting worse as we accumulate miles. Will be taking to dealer very soon. Not throwing a code or light yet, but obviously something is wrong.

Mileage: 10,000

July 15, 2022 - lost power on I80 during heavy traffic. I had to pull to the side as I could not accelerate. Luckily it restarted and I was able to get home. I took it in for service at the dealership the next day (engine light did not come on until the next morning). I was told it was an issue with the catalytic converter and parts were on backorder but it was safe to drive until the part came in. 3 days ago, on Saturday July 30th, I was in my driveway getting to leave and my Bronco wouldn't start, it turned over briefly and then died. The engine made a loud 'knocking' noise and then complete silence. This was a Saturday so they couldn't schedule a tow until until Monday, its been at the dealership for 2 days and they are waiting to hear back from an engineer. I know it's covered under warranty but I think a recall should be issued before someone dies. I was driving about 60-65 mph when I lost acceleration. There was construction ahead but thankfully, it happened before an off ramp. If it hadn't happened in that spot, I wouldn't have had a shoulder to pull over to.

On May 17th At 6,800 miles my motor randomly experienced catastrophic engine failure and has been at the Ford dealership since. The dealership has not told me anything on how or why this happened other than the motor needs to be replaced. The dealer received the new motor on June 22nd.

The contact owns a 2021 Ford Bronco. The contact stated while driving approximately 45 MPH he heard a ticking sound coming from the engine and then a grinding sound before the vehicle stalled. The contact stated there was no warning light illuminated. The contact stated that after coming to a complete stop there were several unknown warning lights illuminated. The contact had the vehicle towed to a dealer. The dealer had not yet diagnosed or repaired the vehicle. The manufacturer had been informed of the failure. The failure mileage was 2,812.

Mileage: 2,812

We were on vacation in Miami, Florida in February 2022 driving in stop and go traffic when our 2021 Ford Bronco with 2.7L Ecoboost engine suddenly shut down. The entire electrical system shut down and the emergency brake was applied. We were unable to start the vehicle with the ignition button or key fob. Traffic was backing up behind us and we couldn’t put our hazards on to let them know we were having vehicle trouble. A pedestrian tried assisting us with pushing the vehicle but due to the parking brake being applied it wouldn’t move. As a last ditch effort I decided to try to start the vehicle through the Ford Pass app. Thankfully, that worked and the vehicle started. We called a dealership in Miami to see if they could look at the vehicle before we traveled on to Key West. They were unable to get us in so we traveled to Key West. The Ford dealership in Key West was gracious enough to look over the vehicle and errors we received on the Ford Pass app. They did not find anything that would have caused the issue. We were just thankful we were on a side road in stop and go traffic when this happened rather than driving on the highway at 70 mph!

Multiple times the engine has failed to respond to the accelerator pedal when engaged from a cold stop. The delayed response has happened several times while attempting to merge into moving traffic so even a 1 second delay is both dangerous and scary from a driver perspective. The vehicle was taken in for service recently and no problems were identified after mechanic testing. However, I wonder if this problem is related to the ongoing investigation of defective valves in the 2.7L EcoBoost engine.

Engine locked up with 1,255 miles. Seemed to be running fine, then heard a noise and unit started to deselerate and started clicking. Was lucky enough to be on a local four lane road and coasted to a school zone pull off. Tried to restart and would not catch. Starter would stay engaged with foot taken off of brake. Had the unit towed to the dealership and the engine was replaced in about a months time. Hopefully this engine is good as it seems to accelerate better much better. My dealer did repair, but my concern is the value going forward. The Bronco is still valuable for resale, but that's having all original numbers and this one no longer does and it will of course show up on a Car Fax and I'm afraid my resale value will decrease for theses reasons.

About 1 hour into our trip the vehicle started to shutter while at highway speed, no warning lamps or notices were indicated when the shutter started and I assumed it was a road vibration. We came to a stop sign about 2-3 miles after the shutter was noticed and the vehicle stalled at the intersection and would not restart. At that point the check engine light, in dash notifications and Fordpass app notices indicated a serious mechanical malfunction. The vehicle needed to be put in neutral and pushed to the side of the road by me and my son to clear the intersection. Ford roadside assistance was contacted and a tow truck was dispatched to take the vehicle to the closest dealership. We sat at the side of the road for 2 hours waiting on the ford dispatched tow truck. The vehicle was towed to Ford of Clermonth. The Ford of Clermont, Florida service department ran diagnostics on the vehicle the next morning(12/06/21). The Ford service technician, following Ford's diagnostic directions, determined there was catastrophic engine failure and Ford immediately authorized an engine replacement. As per the attached service invoice the Ford Service technicians determined it was a valve failure that caused the engine failure.

According the the service department at the Dealership, the valves on my vehicle's engine failed and caused a complete engine failure.

Engine completely destroyed with no notice at 4600 miles destroyed itself in less than three minutes while driving. New engine replaced

Engine died, won’t start again

8:28pm 6.8.2022 - Bronco was towing 1 boat on a single axle trailer (total weight less than 3000lbs). - First soft top convertible roof panel was open - Music playing at medium volume to drown out adjacent highway noise - Heading NE on the Highway 820 feeder road. - Stopped at stop sign at intersection of Cahoba Drive. - Pulled out of intersection and was traveling on a slight uphill at 18pmh - Interior of vehicle smelled sweet and we noticed white smoke filling behind the vehicle - Warning lights for Battery (red battery) and Service (wrench) came on and then a warning to stop vehicle and restart engine. This coincided with a sudden decrease in power. - Pulled to the side of the road to a safe position and powered off the engine, allowed several minutes for it to cool then attempted to restart the engine with no luck. Service (wrench) light turned off and Check Engine light came on. - Open hood to allow engine too continue to cool and to check for exterior engine damage. - Documented current state of vehicle with photos. - Had Ford tow to Grapevine Ford in Grapevine, TX. 8am 6.9.2022 - Service Advisor reached out to confirm vehicle was in shop and would be looked at this week. - I advised that based on the engine build date on the engine sticker, this vehicle was in the batch of potentially faulty valves from the Lima facility. He said he and Ford had no knowledge of potentially faulty valves and that the tech would perform the necessary checks. 10am 6.10.2022 - Service Advisor & Manager reached out to advise that one spark plug was sheared off and that the engine would need to be replaced and possibly the turbos; FoMoCo would confirm what to replace. They actively avoided any discussion of the valves and did not respond when I mentioned them. I verbally requested copies of all videos/photos/reports related to my vehicle and access to parts. 1pm - I requested via text message to Scott Service Advisor access to the my request above. Dealer to follow up next week

While pulling up to a yield sign the vehicle lost all power and shut off causing it roll past the yield sign and come to a stop in traffic blocking the roadway. The vehicle was towed to the Ford dealership and after being diagnosed it had a broken valve that caused catastrophic failure to the engines head and caused the head of the engine to be replaced

Engine failure. My wife was driving the vehicle and was enveloped in smoke and the engine stopped and she was stuck in the middle lane of a busy road in rush hour. A dangerous section of road a few miles from our house. I drove down and gave her my SUV and then called AAA who towed it to the dealership. The motor was dead. The vehicle was towed to Future Ford of Sacramento. They then diagnosed it a few days later and informed us that it is a complete engine failure and that it will take several months to get the vehicle back to us. There were no warning lights or any warning prior to the engine stopping and a large amount of smoke to the point that my wife thought the whole vehicle was on fire. Four people stopped to help her and get her to the side of the road.

at 2,000 miles the engine dropped a valve. Vehicle has already received a new engine. Vehicle shut off running down the interstate. safety was had to coast to shoulder and wait on tow truck.

On Monday, March 7, 2021, my Ford Bronco First Edition with the 2.7 engine experienced catastrophic engine failure. I was driving near my home when my vehicle stopped running. I did feel a strange pull in my steering and tires; but I was also driving on ice and assumed it was the traction control system at play. I was wrong. It was my engine losing compression and my engine failing. My dash lit up with a series of errors (all in quick succession and could not catch them all) and my vehicle lost all power and control. As mentioned above, I was driving on ice covered roads and had difficulty steering. I attempted to pull off the road and into a parking lot; however, the drive sloped up and I could not get clear of the entryway. I had to stop blocking the entrance to the veterinarian's parking lot. To increase the risk here, my vehicle was not visible from traffic turning in because of snow banks that were taller than my vehicle. I want to stress how incredibly lucky I was that this happened close to home. I went on a road trip and had returned home the night before. We had contemplated taking the Bronco. If we had, we would have broken down on the Parks Highway in Alaska. This highway is remote at most times with spotty cell service. The risks of having broken down in subzero temperatures with zero help was extremely high in my area. I also consider myself extremely lucky that I had a friend that was able to come move my vehicle from blocking the business entrance. When I used the Ford app to get a tow, it quoted me 7 hours. I did call and complain that that was unacceptable. The vehicle was towed to the dealership and catastrophic engine failure was determined with a faulty valve being the contributing factor. This is a known valve issue and I have included my engine build date sticker in the photos. I included a photo of my Bronco being loaded on the tow truck showing the ice roads and snow bank blocking my car from view.

I was driving to work on the morning of March 14, 2022, on the highway approx. 70 mph. I felt a falter or engine buck, I began to lose power to the engine. The engine light began to flash and I was only able to drive 55mph. I was in a very unsafe area on a highway with a very narrow shoulder and so I proceeded to manage my speed to reach work safely. I was able to make the additional 10 miles to my workplace. When I stopped at the gate for security, the engine died and I was unable to restart it.

After 625 miles the low engine oil pressure alert came on. Had vehicle towed to dealership. After inspection they stated the engine will need to be replaced. It has now been two months and I’m still waiting for my vehicle to be repaired.

I was on cruise control going about 70 yesterday when I lost all power at the gas pedal. I made it to the side of the highway and waited 90 minutes for a tow truck to come get me. I had my dogs with me and it was 25 degrees out. We were three hours from home. The service department reported today that I had a catastrophic engine failure. A valve came loose and was crushed by the pistons or some such.

My 2.7L V6 engine dropped a valve, it was inspected and determined by the dealer. This happened after a 1 hour freeway trip on Christmas Eve. Luckily, the incident was in my driveway after shutting off the engine. If it would have happened minutes before we would have had complete power failure at 65mph. The problem was determined to be a defect and was replaced under warranty by the dealer. Unknown whether Ford has done a post mortem inspection. No warning whatsoever prior to failure. It happened on shut down so no indication of an issue until attempting to restart 2 days later.

My vehicle started showing power loss, and within 1 mile of driving completely died and refused to restart. The dealership diagnosed the engine as having dropped a piston and will require a full replacement.

The engine blew at 6,976 miles.

Was driving my son to school, maybe 30 mph when all of a sudden I heard some clicking noises from the engine. The power dropped and I was barely able to pull over to the side of the busy road out of harms way. Engine dead. Only warning lights I got were a forward sensor failure and then a message telling me to pull over put it in park and restart. I tried but I was not able to restart, the starter fired but didn't seem to engage with anything. Got towed to the dealer. Dealer confirmed a dropped valve and engine failure. Awaiting a replacement engine.

Engine cut out in the middle of road driving in heavy traffic and would not restart. Vehicle was stranded and had to be towed to dealership. Driver and passengers had to exit vehicle into traffic to avoid dangerously sitting in disabled vehicle on road with significant traffic. Passenger and driver waiting in rain for tow truck to take vehicle to dealership. Dealership has stated engine has seized and can not turn over with starter or manual crank.

Engine stopped in parking lot. Would no re-start. Towed to dealership.

Engine seized when coming to a full stop at a light. Shut off abruptly and shook the vehicle. Would not crank the engine over at all. Towed directly to the dealer 12/31/2021.

On 12/11/2021 at 1,166 miles and after 35 days of owning the new vehicle I was traveling on interstate 40 about 400 miles from home. I was doing approximately 80 mph on the highway when the vehicle shuddered. Luckily right in front of an off-ramp. So I quickly pulled on the off-ramp. The engine light and several alarms went off and the vehicle died while traveling on the road. I was able to pull close to the side, but still in traffic. The engine was dead. It melted. It died on the highway, at high speed, with other cars around, with 1,166 miles on it. Brand new. It is still in the shop two months later.

I experienced complete motor failure while traveling on the highway near my home. I was able to move across traffic to the shoulder of the highway. The vehicle would not re-start, and a tow service was required to take it to the dealership. They have informed the the motor is blown, and will require complete replacement. The vehicle has 6,600 miles and is fully covered under warranty. There were no prior warning or alarm indications, smoke, noise, etc to indicate and issue. The pertinent engine information is included in a picture as attachment.

Driving in town at a speed of 30 mph (speed limit 35). Engine dropped a valve. Engine was destroyed internally and locked up. I quickly put the transmission in neutral and pulled off to the side of the street. This could have been a bad accident if it had happened on a highway at speeds. Ford has an issue with these engines. They know that there is an issue and they are waiting on them to fail and then fix them. I am a member of a forum (www.bronco6g.com) with a few bronco owners and there are at least 35 engines that have failed. Someone is going to get hurt or worse.

One of the engine valve rods failed and punched a 3" hole in the engine block. I was traveling about 70 MPH when the engine light came on and the vehicle started to loose power. At the time I was on a major highway and barely had enough time to get off on the shoulder before the engine quit entirely. Fortunately, I had enough time to get off the highway, but what if this had happened somewhere on a highway where I could not safely pull off on the shoulder???

The contact owns a 2021 Ford Bronco. The contact stated that while at a stop sign, the vehicle experienced a catastrophic engine failure. There were no warning lights illuminated. The vehicle was towed to the local dealer where it was diagnosed that the engine needed to be replaced. The vehicle was repaired after several weeks. The manufacturer was notified of the failure however, no further assistance was provided. The approximate failure mileage was 2,322.

Mileage: 2,322

On November 14th, 2021, the 2.7 ecoboost engine on my 2021 Bronco, with 2744 miles, shut off without warning. I was traveling on the interstate, going approximately 75 mph, with my girlfriend and elderly mother as passengers. The Bronco lost all acceleration and the "service engine" light came on. Fortunately, I was able to coast to the nearest exit ramp. After bringing the vehicle to a stop, I attempted to restart the Bronco to no avail. The starter would engage, but the engine would not fire back up. I unhooked the battery cable in an attempt to reset the electronics, but this did not work either. I then checked to make sure all of the fuses were tight, but the vehicle still wouldn't start. The vehicle was transported to the nearest Ford dealership. After 6 1/2 weeks at the dealership, the Bronco's repairs were finally complete. The dealership had to replace the entire engine. Based on the paperwork given to me by the dealership, cylinders 4, 5, and 6 had low compression, cylinder 6 spark plug was found mashed from the piston, and they found catastrophic failure in cylinders 4, 5, and 6. Also, the paperwork states that metal was found in the oil, cylinder 6 intake valve was found in the intake manifold, and metal chunks were found in the intake manifold and turbos. Needless to say, we were all pretty shaken up over losing complete acceleration and power on the interstate. We were very fortunate there was an exit ramp close to us, but this could have turned out very differently. I feel like we were unnecessarily put in a dangerous situation in an essentially brand new vehicle.

While driving on interstate engine shut off. Was able to get to side of the road easily because it was late at night. Was not able to restart once coming to a complete stop. Had towed to dealer. Dealer could not get engine to start. Dealer found what looked to be a dropped valve. No indicators on the dash as to what was happening.

pulled up to stop light. car shuddred coughed and conked out. Got it started, coughing and sputtering. Made is 2 miles to get home. Had it towed to dealer. Dealer first said I got water in engine. There is no way that happend. Then they said ford will be paying for it to be repaired. 4,400 miles on her.

broke down with 2058 miles. Flashing engine light, strong fumes smell and vigorously shaking. Ford customer care said there’s nothing they could do. Not even a loaner for a $63k vehicle.

Without any warning lamps, messages or any other symptoms, lost acceleration power going roughly 45mph. I was traveling on a rural road, but this could have caused a serious accident if this would’ve happened in traffic or a highway. Dealer diagnosed a dropped valve in 2.7L engine, almost 2400 miles.

The 2.7 L engine failed going down the interstate in the middle lane. Complete loss of power. Was fortunate to be able to coast to the shoulder. Dealer says the engine failed and needs to be replaced.
