Leff than 6 months after purchasing this vehicle new I have had a problem when I'm turning right or left with a rubbing/grinding noise in the rear. I have complained about it to the dealership where I was getting my oil changed and they brushed it off saying they don't hear it or it could just be the wind lol. I ended up taking it to another dealership in 2023 (Oxmoor Ford) where they heard it and diagnosed it as my rear differential and after they had my car for 3+ weeks I was told there wasn't a fix and they would just change out the fluid and replace it with new fluid and would let me know when there was a fix. In October 2024 I call and ask about this fix because I never heard anything else from them and they have me bring it in just to reset the modules. Still no fix on rear differential with so many complaints about it from several Bronco owners.

My car was stopped at a red light and when I hit the gas to go my entire car shut off. I was not able to turn my hazards on or put my car in neutral to push my car out of traffic. This is a huge safety concern because a car could-??ve rear ended me since I wasn-??t able to put hazards on. I attempted to jumpstart the vehicle but that didn-??t work. I had to get my car towed and sent to the dealership. The issue sounds like the recall notice 24S24 - however my bronco sport says I don-??t have any recalls. After talking to other bronco sport owners who had similar issues, they said they had to pay several hundred dollars to replace the battery with an AGM battery because the bronco sport isn't equipped to handle all the electronics.

My transmission is slipping and the vehicle is sputtering at take off. There is a burning smell from the engine of my Bronco Sport. I have seen recall issues on other 2021 Ford Bronco Sports but my VIN is not included. It says that Ford issued for 2021-2024 Bronco Sport for transmission issues. Stating that the transmission park system may have been damaged during assembly. Dealer is saying I need new torque and valve body. Other Bronco Sport customers are also reporting the same issue on Bronco Forum. This vehicle is needed for transportation to and from work for my son.

Currently at 30,000 miles. Water pump goes out every 10k miles, rear differential went out, front control arm and strut went out.

- Medina, OH, USA

I've had 3 water pumps replaced first one was right before 36,000 miles, 2 were after the bumper to bumper warranty. Had the rear drive unit replaced for grinding, that was at about 28k miles, torque converter was also replaced at about 35k miles, oil leak from my camshaft carrier gasket, thermostat housing split, battery replaced after a year. This vehicle has been nothing but issue after issue. Each time low coolant, no heat in the vehicle. No warning lamps, nothing to tell me it was low.

- Pittsburgh, PA, USA

My 2021 Bronco Sport has had its water pump replaced 3 times and today I discovered the one put on in July 2024 is failing again. Each time it starts to fail there are no warning lights for low coolant. If your not actually checking the coolant reservoir under to hood consumers have no idea the water pump is leaking and failing until it's possibly too late and your vehicle overheats possibly causing more issues. This is a known issue by Ford, but no recall has been issued nor have these faulty water pumps been redesigned or updated to resolve the issue. Unfortunately, you see no coolant drippings where you park due to the fabric skid plate that covered underneath absorbing the coolant as it leaks out.

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.

- Dallas, TX, USA

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.
