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 entering a gas station, the check engine light came on, and the vehicle began losing power. She parked and immediately contacted the Ford dealership. They advised her to not drive the vehicle and have it towed to the nearest dealership (She was in Pennsylvania picking up our daughter from college). It was determined by the dealership in Pa. that compression in a cylinder was down 5% and the vehicle needed a new engine. We had the vehicle towed back to Virginia and inspected by the dealership who services the vehicle. Parts of the engine were removed for visual inspection at which time a crack intake valve was found, confirming the engine was no good. Also, confirming the issue Ford had stated in its recall. All information and pictures were sent to Ford manufacturing for determination on fixing the problem. Ford has said they will not cover the total cost to make good on their recall because the vehicle was out of warranty (miles were exceeded). How are consumers protected from manufactures taking advantage of mileage? The SAFETY recall was issued long before the warranty ran out. What if my wife had crashed w/ our daughter?

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.

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?

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.

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.

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.

When my vehicle was warming up I noticed two plumes of smoke coming from the muffler area. One plume was the tailpipe and the other was shooting straight down from underneath the vehicle. Upon inspection I found a whole in the bottom of the muffler. There is no denting or impact damage near the hole. There is exhaust stains on the muffler ranging from the hole towards the rear of the vehicle. The exhaust stains show evidence that the whole and the exhaust leaking out has been taking place for quite some time. It is obvious the muffler rotted.

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.

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.

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.

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.

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.

Engine failed and replaced under warranty.
