In 2021 i purchased a brand new Bronco Sport Big Bend with the hopes that it will last as long as the previous Bronco models. Unfortunately, 3 years later i took the vehicle to a Ford dealership, and to my surprise the transmission needs to be replaced. Being a vehicle that is regularly driven by my pregnant wife is an issue that Ford needs to be accountable for. There were no engine lights on, the only warning was a noise i noticed when driving the vehicle myself in the highway. I understand that transmission failed throughout the course of the years, but to a 3 year old Ford Bronco Sport is just ridiculous and not safe at all. The vehicle is currently at the dealership, Ford has agreed to pay 5k towards the replacement but i still have to come up with more than 7k to get it fix. If i knew i would be having Transmission issues so early in the life of the vehicle, i wouldn't have purchased a new car in the first place. This is definitely a safety hazard and i am sure this is not the only Bronco Sport with a torque converter being faulty, causing the transmission to slip.

2nd time my Bronco Sport has had an electrical failure. Has already gone thru recall and now has left me stranded again. 1st time in rush hour traffic and this time at 1 yr old son-??s daycare.

- Fort Worth, TX, USA

This newer 2021 Ford Bronco Sport stopped working and lost all power on Feb 21, 2024. The vehicle had just 37,031 miles on it. To problem solve, A neighbor jumped it. I turned the vehicle off after a few minutes and it would not turn over and start again. We jumped it again and let it run for about 10-15 minutes. Thinking it was safe to drive, I turned out of my parking lot thinking it was fine and the vehicle began to shake and putter as though it was losing power. It felt unsafe to drive it so I pulled back into my driveway and had it towed to the dealership for repair. Ford dealer told me it was the battery. Since then I-??ve had issues with the drivers side window getting stuck when rolled all the way down, sometimes the vehicle has a hard time -??catching-?? to start when I press the break and the power button simultaneously, it also feels like its lulling into between gears when I am going at a low speed. Basically the Vehicle feels like there is an electronic issue. I paid $517.50 for a new battery and labor. A battery should not be failing at 37k miles on a car that was bought brand new. I-??ve leased and bought brand new cars since 1992 and I-??ve never had to replace a battery on a new vehicle. Now, for the past week, this vehicle feels very tight and sounds like it-??s almost grinding when I turn right or left out of my parking stall at home. It feels like there is a power train issue.

This vehicle was taken into a Ford Dealership for service. A mechanic friend of mine drove the car and said, he thought it might be the right front cv axle. The ford service department said that it was a vent hose sending contaminated fluid to the rear deferential. The service guy said he is seeing this a lot with 2021 Broncos. This problem doesn't seem to be covered under the Powertrain Warranty and there doesn't seem to be a recall on this issue. The service department wants to charge almost $1400 to fix a problem that seems to be a manufacturing issue. I feel that Ford needs to look into this and correct the issue, because we don't really have that kind of money laying around, but because the car is close to 60 thousand miles, I'm sure Ford will not do anything but it's too late to be covered. I have to get it fixed.

Verified noise concern, found TSB 24-2185 This may be due to contamination of the rear drive unit (rdu) fluid through the rdu vent hose. To correct the condition, follow the service procedure to replace the rdu vent hose. SAFETY CONCERN IS THE POWERTRAIN. HAS BEEN DIAGNOSED AT FORD DEALERSHIP.

After fueling up at a gas station, my 2021 Ford Bronco Sport would not start. When I tried, all of the lighted features started strobing, flashing, and cycling through very quickly on my panel. I called Roadside Assistance, and they jumped me. It was a 50-minute drive home, so it gave the vehicle ample time to recharge. The next day, it would not start. I am waiting for a Roadside to jump me again so I can take it to the dealership. (Suggestion: ability to load video.)

exhibits a chatter/shudder during low speed turning events. This may be due to contamination of the Rear Drive Unit (RDU) fluid through the RDU vent hose. To correct the condition I have to follow the Service Procedure to replace the RDU vent hose. the drain tube for the rear differential gets clogged from road debris and dirt gets into rear differential. The repair is rerouting drain tube (new part) and changing fluid.

On days when it rains or the weather is slightly cold/dewy, the Ford Bronco seems to make a screech/horn-like sound only when reversing. I found some online forum links (listed below) where other Ford users seem to describe the similar issue we're experiencing. This is the second dealership that we have taken the vehicle to be serviced for the issue, but they have both stated there is nothing they can do because the issue has not been issued as a recall. [XXX] [XXX] [XXX] The first dealership visited for service was: Metro Ford Sales & Service, Inc. Address: 6455 S Western Ave, Chicago, IL 60636 The second dealership visited for service was: Napleton Ford of Oak Lawn Address: Address: 6100 W 95th St, Oak Lawn, IL 60453 The attachment includes the most recent appointment visit. Unfortunately, I cannot provide an invoice at this time because the vehicle is still at the dealership (10 days after taking it in). I visited the dealership yesterday (08/12/2024) where I was informed that the the service technician working on my car is in the hospital. Had I not visited, then I probably would not have known this, and the other service technician I spoke to said they could not share any more details since they were not part of the servicing for my car. Martin Garcia (mgarc520@ford.com) is supposed to be the middle-man between me and the dealership to help me address the issue, but I have not received information from his end either. When I called the Ford's number using (866) 631-3788 to get a hold of Martin Garcia, someone else assisted and I was told that he would call me tomorrow (08/14/2024) to give him an update on what the dealership shared with me.

Loss of power. I was traveling after work and heading to family-??s resident. I was on the freeway and noticed the engine light come on then followed by a loss of power. The slightest 1 degree difference incline had the vehicle lose 20-30 mph while on a highway of 65 mph limit. I turned around the it made every little climb dangerous to drive. Luckily I was heading back home while it was nearing midnight. The freeway was especially free of the normal traffic. Im glad I made it home safely but the slightest incline while on a 75 mph limit freeway was dangerous when I dropped to 35-40 mph. I took my vehicle in to the dealership. Upon a diagnosis, they found the solenoid to have short circuited. Last thing I heard today from the service advisor was the part needed is now on back order.

AWD Module tested internally bad when assessed by local dealership. Vehicle was taken in for assessment after a software update recal was completed as vehicle then started stating vehicle had a powertain malfuntion, Pre-collision system was off, Hill.assist was off, Traction control was off, 4WD unavaialble, AWD unavailable. The dealership AND Ford Customer Service states that this was not covered under the warranty as it was not a powertrain malfunction but rather and electrical issue. I researched and found Customer Satisfaction Program 21B19- AWD Module Replacement was filed with NHTSA ID Number: 10191184. Which has my vehicle make, model and year stating that there was in fact a known issue. I was never notified of this issue and am now being told my problem is only electrical and not covered under my warranty resulting in me having to pay out of pocket to correct a KNOWN problem that has been documented.

- Wurtland, KY, USA

Due to a defective original design, the vent hose for the read differential unit collects environmental contaminates and causes chatter and slipping in the differential. This can cause degredation of the gears which limits the ability to drive and control the car. See TSB 24-2185

The rear axle differential. The rear axle is making a bumping and grinding noise upon acceleration and when turning at low speed as if the axle is going to fail. It happens during right and left turns but right turns are worse. The vehicle was taken in for diagnostics, and there is a TSB for suggested repairs. The parts needed to be ordered.

I recently had the recalls addressed (despite having any issues with the vehicle). Days later, I noticed my vehicle would occasionally not detect my key fob. Changed battery without resolution. On 6/27/24, I was driving in rush hour traffic, and stopped with the red light. When the light turned green, I went to drive, and the car shut itself down. Everything shut down. Couldn't even turn on my hazards. While waiting for a tow truck, I received a tip to use the key fob to push the start button, and that actually worked. I took it to Ford, and they returned it 12 days later with updated modules (they stated they couldn't diagnose the issue which is fascinating to me considering the nature of the recalls and all the information I am able to find online). 10 days after having it back, the vehicle hesitated to start and displayed a 4wd fault error. Contacted Ford immediately. The next morning, I started the car and the errors were gone, but I still wanted to get it checked out, so headed towards Ford. Stopped for gas on my way, but after filling up the tank, my car wouldn't start again. This time far worse than the first time, as something under the hood starting making a clanking noise, and smoke started coming out from under the hood, and smelled like electrical fire. The noise continued to get louder, and the smoke more violent. Finally cut the battery cable since the car was smoking, at the gas pump, on a busy Saturday, minutes before noon. Very scary situation, especially with kids in the car. We are OK. We are safe. But holy crap!
