2021 FORD BRONCO Engine Problems

A Safety Recall was issued on the vehicle with no remedy. The recall was in reference to the Engine Intake Valves and stated; "The engine intake valves may crack and break, which could result in loss of motive power and increase the risk of a crash". It also stated, " Prior to losing motive power, an engine malfunction indicator lamp may illuminate in the cluster and the driver may notice that the vehicle is running rough". This issue was the result of Ford manufacturing using a material that had "hardness issues". This all came out prior to the vehicle reaching the end of its warranty mileage. A test was required on the engine at the dealership at which time, the technician determined there was no need to perform the "recall test" (confirmed by video sent to us). On or around Dec. 17th, while my wife was driving the vehicle and...

Component or system that failed or malfunctioned: The fuel delivery system, specifically the fuel pump, which is subject to an active safety recall. The recall states that fuel pump failure can result in loss of fuel pressure and flow, leading to engine stall. The vehicle is available for inspection upon request. How safety was put at risk: A sudden engine stall while driving would result in an immediate loss of propulsion and power, creating a significant risk of collision, particularly at highway speeds or in traffic. This creates a dangerous situation for the driver, passengers, and surrounding vehicles due to the inability to accelerate or maintain speed. Has the problem been reproduced or confirmed by a dealer or service center: The defect has been confirmed by the manufacturer through an official safety recall. At this time, there is no repair remedy available. The vehicle has not yet been repaired due...

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...

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.

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...

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...

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.

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...

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...

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.

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...

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.

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...

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...

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

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....

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...

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...

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.
