Engine And Engine Cooling Problems of Ford Bronco - part 2

My vehicle has the 2. 7l v6 ecoboost engine. This engine apparently has a design defect that results in repeated cam phaser failure. My engine recently had cam phaser failure and I had them replaced. A week later I was driving at speed on a highway when my engine completely died. I had to pull to the side of the road and could not restart my engine. I ended up being towed to a dealership and am awaiting diagnosis.

The contact owns a 2021 Ford Bronco. The contact received notifications of NHTSA campaign numbers: 24v635000 (engine and engine cooling) and 25v025000 (suspension); however, the parts to do the recall repairs were unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that there was hydraulic fluid leaking from the vehicle near the rear struts. While driving approximately 35-45 mph, one fluid reservoir on the driver’s side rear strut detached from the vehicle. The contact continued to drive to an independent mechanic. There were no warning lights illuminated. The vehicle was taken to a certified mechanic who diagnosed that both rear struts were defective and needed to be replaced. The vehicle was towed to the dealer, and the contact was informed that the repair was not covered under warranty. Additionally, the parts were on backorder. The vehicle was towed to another mechanic who replaced the struts. The manufacturer was made aware of the failure and opened a case. The manufacturer referred the contact to the NHTSA hotline to request a reimbursement. The failure mileage was 40,000. VIN tool confirms parts not available.

We installed new tires and wheels on our vehicle and it immediately started having engine problems and the check engine light comes on. We took it to the dealer and after several days back and forth Ford told the deal that it's a known problem with the 2. 3l version of the Ford Bronco however they had no fix and no timeline to fix the problem. This creates a safety hazard as the engine program can't be updated and could cause damage to the engine and cause it to fail. The dealer then stated that they could not return the vehicle to us with the new tires and wheels we purchased and we had to put our old tires and wheels on. We counted on the old tires for a spare since we already blew one tire out. So in addition to a safety hazard we are currently out $2,500 we spent on new tires and wheels, and now have to purchase another tire of the exact same original size to have a spare, costing us another $300.

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!.

The contact owns a 2022 Ford Bronco. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed and determined that the spark plugs had failed to remain connected. The spark plugs were reconnected. The next day the check engine warning light illuminated. The vehicle was returned to the dealer where it was diagnosed with the same failure. The spark plugs were replaced. The failure reoccurred and the engine sounded as if the engine was sputtering while starting the vehicle for several minutes. The vehicle was returned to the dealer where it was diagnosed as spark plug failure and that the engine was misfiring. There were no dtc codes retrieved. The vehicle was not repaired. The manufacturer had not been made aware of the failure. The failure mileage was approximately 35,000.

Vehicle dash getting frozen and engine stalling making unsafe to drive because you don’t know the speed the you are traveling, you have to park, the vehicle and is taking time to get back on and problem keep happening, I have been in Ford dealership and not solution has been made also have file a complaint on Ford cxh02468902 and not response at all not calls or emails they just avoiding look at the issue I’m not the first person with the same issue, this vehicle is unsafe to drive on any highway or roadway I will attach the onformation where Ford is saying the vehicle has issue but they don’t have the fix yet it should be taking out the market from Ford.

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.

When driving or breaking at slower speeds, the car feels as if the transmission is “slipping” and the car jerks forward. The same thing happens when braking the car.

My 2023 Bronco with 6k miles died without any warning back in late January 2024. Ford service dept said it was a failed catalytic converter. After it was in the shop for a 1. 5 months, waiting on the back ordered part, we picked up our truck around March 10. Fast forward to today, truck has 7k miles. We were southbound on the interstate in bumper to bumper traffic heading to disney world when the truck’s engine died, yet again. Luckily we were not traveling typical interstate speed and we safely maneuvered the vehicle to the side of the road and contacted Ford roadside assistance and a tow truck was quickly dispatched. The truck is currently sitting at a Ford dealership on a Sunday, 485 miles from home and a lot of money tied up in our vacation plans. Just thankful nobody was hurt, but waiting for this to happen a third time just to file a lemon law is reckless to customers and everyone else on the road, for that matter.

While driving the vehicle began to misfire and became unsafe to drive. It was towed to the local dealer where error codes confirmed that cylinder 4 had misfired. Ford was unable to duplicate the issue nor where they able to find any issues that would have caused the misfire after trouble shooting.

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.

There is a major lag in the time from when you hit the pedal to when you start accelerating, almost like a pause. Hesitation, long lag or dead spot in accelerating. Failed to accelerate from a stop at least 3 times.

I was driving uphill in a neighborhood going about 15 mph when my Bronco suddenly lost power. I was not able to restart and had to manually restart the truck using the fob to ignition method. It started back up, but a terrible sulfur smell was coming from the vehicle. I brought it into our nearest Ford dealership and they claimed there was nothing they could do because no code was reported from the truck. I continued to drive it for another day and the check engine light came on. My Ford pass relayed a message claiming that the issue was the catalytic converter. I took it to my Ford dealership who claims this could take months to fix because the parts are on back order. My 2023 Ford Bronco, 2. 7 liter v6 had less than 6k miles.

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.

Battery charge, over heated, failed power train, and failed 4x4 happened all within seconds of each other. We were on a 2 lane hwy where there was very little room to pull off the main road. It was christmas eve and we were about 60 miles from home. We had to pay around $400 dollars to have it towed home and it was freezing outside while we waited.

The vehicle experienced recurring electrical system failures beginning in December 2023. The vehicle intermittently would not start and on several occasions lost power unexpectedly. The vehicle was taken multiple times to an authorized Ford dealership for diagnosis while still under the manufacturer warranty. The dealership repeatedly reported that no issue could be identified despite the recurring electrical malfunction. The vehicle battery was replaced more than once within three years, however the underlying electrical issue persisted. In August 2025 the dealership instructed that the vehicle remain at the service center for extended diagnosis. The vehicle remained at the dealership for more than 40 consecutive days before being returned on October 8, 2025. Because the vehicle intermittently fails to start and has experienced electrical system malfunction, this creates a potential safety risk if the vehicle stalls or loses power while operating in traffic. Additionally, the vehicle currently has two outstanding manufacturer safety recalls that remain unresolved after nearly three years of ownership. This complaint is being submitted because the defect remains unresolved despite multiple repair attempts while the vehicle was under the manufacturer warranty.

Engine service light came on indicating reduced power/power failure. Called Ford dealership and they said to bring it in ASAP. After diagnosis the Ford dealership said there was a problem with the wastegate. The dealership has no eta on when the part will be available.

Not exactly sure how it started to happen. Meaning there was a powertrain malfunction so my Ford computer tells me, which caused the vehicle to not restart and in addition to it not restarting, the vehicle also didn't have brakes, so it simply rolled backwards without any control until I hit a tree to stop me. On the way down, I also hit the bumper and damaged it and also hit the driver's side mirror on a rock on the way down.

Driving down the road on 10/31/23, all of a sudden the entire vehicle started to shake, then the check engine light came on, then the vehicle started shaking even worse- losing power and sputtering. Pulled over and had it towed to dealer- buckhannon wv- they checked the compression and found nothing. I am still waiting for someone to look at the vehicle's engine to determine the issue- I have not even owned this Bronco for 3 months when this happened. It only has 24000 miles on it. It left me stranded along the highway- my friend had to come and pick me up. I currently have no vehicle to get back and forth to work. Its sad that you pay such for a vehicle so you don't have to worry about getting back and forth and now it looks like I will be waiting for months- no Bronco and no one seems to be concerned.

My Bronco started having issues randomly when it went into limp mode one day. I brought it in to get fixed and it continued to happen. Ultimately, they told me that it needed a brand new engine.

Good day! Bronco 2021 (VIN 1fmee5dp4mla68250) - my engine suddenly broken while driving - I heard some unusual clicks-knocks from the engine side, check engine lamp apperared. I stopped vehicle, look under the hood and saw puddle of oil under the engine (car mileage about 7000 miles). Service man said that I should buy a new engine - old one broken with no chance of repair. . . How can you help me? thanks.

2022 Ford Bronco loss power while driving moderate speed (35 - 55 mph) and would not immediately restart after the first attempt. After finally restarting it would continue to stall. The car was towed to the dealership where after four weeks of investigating they found the catalytic converter to be melted. The car has now been sitting at the dealership for 7 weeks with an "indefinite lead time" on replacement parts. My Bronco only has 14,000 miles on it and no determination on what caused the catalytic converter to melt.

Multiple lights on dash turned on also check engine light' loss of power and jerking of vehicle.

Once the vehicle hit around 3000 miles it started making a loud clicking noise while the vehicle was running parked or driving . The noise continued to get louder. When I called new brighton Ford where I purchased the vehicle brand new on 4/25/23 at the end of June I was told to make a service appt. The soonest they could see the vehicle was 4 weeks later. Because of the continued noise I called on about July 12 2023 they agreed they would look at it upon looking at the vehicle. It was found that the engine was in engine failure. They kept the vehicle for six weeks and had to replace to the engine.

My engine in 2023 Ford Bronco with approximately 2900 miles failed in lunch time traffic. The dealership is saying they have to order me a new engine. This is borderline criminal.

My engine has had a knocking problem since 3000 miles. Everytime I take it to Ford they agreed it has a knock but won't fix the problem stating it's normal and some engine knock more than others. The engine knocks at low rpm when stepping on the accelerator then smooths out about 1500 to 2000 rpm. One mechanic said it's an issue but they won't fix it unless it has a catastrophic failure this is unacceptable to me as they just want the vehicle to fall out of warranty when the engine finally gives way and doesn't turn on anymore. There are multiple Ford vehicles that have this issue and Ford does not seem to look into it and fix it please investigate the issues with knocking on all the Ford vehicles with the ecoboost engines.

We have had two major issues with this new vehicle. It has less 1,872 miles on it and it is only about 2 months old. Within a week of owning it, the stabilizer bar went out and render the vehicle un drive able. We have a second issue that is even larger safety issue. The vehicle is now dying and leaving you stranded on the side of the road. We have now had this happened to us three times on separate occasions. Once was on a trip back from oklahoma to dallas and the highway is under repair/construction and there are miles that there are only two lanes with no shoulder or exit to get off in case of auto problems. We found ourself at night that our Bronco lost total power and would not start back up. The vehicle has some kind of timer that will allow you to attempt to start it so many times in a period and then disable the ability to crank the engine. It gives you an error of "cranking time exceeded" so where ever you are "stuck on the highway in traffic, off the road on in your driveway, you will not be able to attempt to restart your motor if you exceed this time limit. This is a very dangerous issue and I feel many people could lose their life if they are in an situation where they can not attempt to start their motor and try to move to a safer location if the engin can be restarted.

Flat towed vehicle behind motorhome. Followed Fords instructions to the letter. Transmission fried even though computer showed flat tow engaged. Ford refused to warranty this issue and blames the operator due to an internal memo. Ford dealerships have acknowledged their is an issue with their flat tow system but Ford refuses to warranty.

While at a stop with vehicle running, the vehicle sputters and stalls when trying to accelerate/start moving. This has happened multiple times when stopped at an intersection and creating a safety hazard for the occupants of the vehicle. Multiple attempts to restart it have to be made and it eventually gets going again but this is very dangerous to be stalled at a busy intersection. Vehicle is going into the dealer to be checked out this week. The only message we have seen is "manual restart required" on the instrument panel.
