Differential carrier replacement due to metal contmination being found in differential during oil change and a transmission overhaul due to excessive wear of(clutch container, CDF bushing, forward hub and front support bushings). They also noted a sticking valve in the main control on my 2022 Ford Bronco 2.7L V6 when taken in to dealership to evaluate vehichle under warranty due to ongoing intermittent thump/clunking noise when coming to a stop and accelerating from a stop as well as when backing up from a stop and while driving as well, intermittent loud metal slapping sound at speeds over 60 mph, intermittent jerking of vehichle when cycling through gears, unexpected downshift at high speeds. After differential replacement and transmission overhaul due to excessive wear while under warranty, my vehichle continues to experience the same symptoms and problems and feel this is a safety issue.

I was driving on the highway with standard cruise control (I don't have adaptive cruise) and I went to press the brakes and the brake pedal was SUPER stiff and I had to press unreasonably hard to disengage the cruise control and slow down. When the pedal finally gave, I ended up slamming on the bakes so much that my passenger was startled and we both lurched forward due to our momentum. Afterwards, my brake light light came on, on the dashboard. I went to AutoZone to get a reading and it said it was the brake assist vacuum or something like that. This could have caused a very bad accident in too different ways. One, if I didn't stop in time due to the delayed braking from the stiff pedal or getting rear ended due to inadvertently slamming on the brakes at highway speed.

when engine is cold and I go down a hill to a stop sign and apply the brakes , the brakes begin to engage almost fully then release and the Bronco lurches forward 6-8" and then the brakes grab and slam the car to a stop. This only happens on an incline and when the engine is cold or has sat for awhile. THe brake pedal is fully depressed and when the bronco rolls forward, there is nothing to do to stop it since the pedal is already fully engaged. I have taken it to the dealer numerous times to diagnose, but since there is not a hill or incline near them, they are not able to reproduce the same issue. I have videos of this happening and it is a known problem that has been diagnosed in the Ford bronco online forums. The dealer suggested I call Ford Service to report the issue and I started a case complaint.There are no warning messages or codes that are present that the dealer can find to explain the problem. The car is not safe to rely on due to the brake system currently and the dealer nor Ford corporate will do anything but document my issue.

Good afternoon! My car started having issues going in reverse before I received the recall notification. It would nearly stall out and happened a couple times prior to getting the notice. Once I got the notice, I reached out to the dealer to see if anything could be done and was told no, not yet. Now, months later, it has gotten so bad that I am having to leave my house when it's cool (it doesn't stall as bad when it's cool out), and park my car in a certain way each day to ensure that I can effectively leave work without my car stalling. What is worse is that now, on hot days, my car semi-stalls, when I am driving on toll roads or back country roads on the way home. It loses power or jerks. I have an hour commute each way and this is NOT okay. Frankly, it is very scary sometimes. I have reached out to the dealership to ask them if it's safe for me to drive my car or if there is something they could do and I am constantly told that there is no solution, I have to wait, and they "legally" cannot tell me that it is safe to drive my car. They offered the option to rent a car, but I would have to pay a minimum of $45 out of pocket, per DAY, and I cannot afford to do that! I am already paying $600 a month for this car, now they want me to pay an additional $1350-$1395 a month just so I can feel safe? This has been going on for roughly 7 months. Who knows how long a "solution" will take. 7 months x $1350 a month = I would be out almost $9500 on TOP OF my car payment with no end in sight. I feel like this is moving at a snails pace. The problem is getting worse and I am getting the run around. No help is being offered to make me feel safe driving this car! They seem annoyed when I ask about it (I have only reached out three times in the last 4 months). The recall even says that it could stall while driving. So, honestly, what is it going to take for me to not die in a crash when my car stops on a high-speed road? Seriously. What can be done?

When my brakes are cold and I stop on a hill...the brakes do not hold and the car moves about a foot forward. Then something kicks in and it jerks the car to a stop (all the while my foot is completely pressed down on the brake. No warning lamps, no lights, nothing...just rolls when brake is completely applied. It only does this when the brakes are cold. After they warm up it doesn't do it anymore. The dealer has looked at it and couldn't replicate (because the brakes weren't cold) and told me to bring it back if it happens again. It happens every morning but by the time the dealer gets it it doesn't do it anymore. A PLETHORA of bronco owners are experiencing this same thing. Our thread on [XXX] is full of people experiencing the same thing. Some guy in Canada said he had every brake part replaced and it still happened. Then they did some sort of software update and he hasn't experienced it since. Why is this update not available to all? This is a serious hazard! Someone is going to get hurt!
