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.
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
The contact owns a 2021 Ford Bronco. The contact stated that while driving at an undisclosed speed, the vehicle made clicking sounds and then lost motive power. The check engine warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed with engine failure. The dealer informed the contact that the engine needed to be replaced. The vehicle was not yet repaired and remained at the dealer. The manufacturer was made aware of the failure. The failure mileage was 923.
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.
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.
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.

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.
