The contact owns a 2023 Ford Bronco. The contact stated that while driving at an undisclosed speed and flat towing an RV, the Flat-Tow mode inadvertently disengaged and the contact smelled a burning odor permeating the interior of the vehicle with the message "Stop vehicle immediately, excessive temperature detected" displayed. The transmission temperature warning light was illuminated. The vehicle was taken to the dealer, who determined that there was damage to the transmission and turbocharger due to the Flat-Tow mode not being engaged properly during towing. The contact was informed that the transmission and turbo charger needed to be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to Technical Service Bulletin: 22-7086. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The contact was later informed that the manufacturer concluded that the disengagement of Flat-Tow mode was the result of user error. The manufacturer declined to cover the cost of the repair. The contact contested the manufacturer’s findings as inconceivable, stating that the Flat-Tow mode was still engaged after arriving at his destination. The failure mileage was 50,200.

Engine began to leak air in intake where this is a faulty problem in the previous two models years and is an active recall on them also, 23 Ford Bronco, began to misfire causing to have to get engine replaced

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.

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.

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.

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.

The contact owns a 2023 Ford Bronco. The contact stated while driving 65 MPH, the power train and service engine soon had warning lights illuminated. The vehicle was taken to the dealer to be diagnosed. The contact was informed that there was bad gasoline in the vehicle, and gasoline needed to be drained from the fuel tank. The fuel tank was drained and refilled; however, the failure recurred. The vehicle was taken to another dealer and diagnosed with a faulty turbocharger. The contact was informed that the turbocharger needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 1,100.

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.

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.
