I bought a 2021 Bronco Sport Brand new and ever since the car has been a problem. The rear axle wasn’t getting enough lubricants so it was grinding and I didn’t know what it was at the time but I took it to a Ford dealership and was told after spending 200$ on diagnostic testing that absolutely nothing was wrong with the vehicle. The vehicle kept doing the same thing grinding noises so I took it in again and got the same results now mind you this is way before my power train was up. The car felt so unstable and unsafe it got to the point where I had to just leave it at the dealership until Ford could help me with some financial assistance. While at the dealership Ford told the mechanic to check the transmission and upon checking the transmission the mechanic found a problem. The total of repairs came up to over 10k for a vehicle that doesn’t even have 65k miles on it. I was sold a brand new lemon. This was my first new car purchase and it has literally been the worst experience in my life. The brakes were recalled the fuel injection system now the battery which I’ve already spent 500$ on a new one last year has guess what? Been recalled as of 1/17/2025. So after thousands of dollars in rental car and Uber rides which I have yet to be reimbursed for my vehicle is still at the Ford dealership has been there for over 3 months out of 10k in repairs Ford offered to pay only 4,100. What a rip off buying this junk was. I really thought Ford would do the right thing and take care of its customers but I was wrong dead wrong. Biggest mistake of my like.

The evaporative emissions system failure involving the purge valve and vapor canister purge valve is a recurrent issue on this car and has been reported by hundreds if not thousand of bronco sport owners. All recall for 1.5L and I am sure the badlands have the same parks and is not included in the recall. less than 60,00o mile with a check engine light on. The safety issue that arises from this is that we are emitting more fuel vapors into the atmosphere. Please add recall to cover Badland if they contain same parks as 1.5L!!!! Also the windshield wiper pump did not work. I can not clean the windshield wen needing to see out of it. i have to pull over and clean at local gas station.

This has been an ongoing issue since I purchased the vehicle in July 2024. It has become so bad that the vehicle is nearly un-driveable. FORD states it is a non-issue, non safety related and there is no know fix at this time. FORD has been buying vehicles back due to this "secret recall" but after numerous calls and visits to both dealers and the Ford customer care line, nothing is being done. And while FORD might state it is an "inconvenience", when driving on the highway and a cylinder just randomly shuts down, the vehicle loses power and backfires and vibrates it is a safety concern. I have been EXTREMELY patience and professional in all my dealings with FORD on this matter, yet they refuse to offer me any help or come to a resolution in my case.

The car has now on three separate occasions lost power while driving. As I slow down coming to stop or reducing speed car will completely lose power and then struggle to restart. Both occasions were on busy roads. Additionally, when you put fuel in the car it does not turn on right away it smells like fuel is burning and fumes enter into the cabin. When you push start after fueling it struggles to turn car on to drive. There is full accessory power but no power to drive the car even when giving it gas. It requires multiple attempts at starting the vehicle and it will tremble and shake once it starts running and stutters as if about to shut off even when you start driving it. Today it powered down again while driving and we avoided and accident but it is becoming dangerous to drive the vehicle due to its unpredictable shutting down.

The vehicle has been in the shop since day one with many many problems! The TURBO failed under warranty so they replaced it without doing proper procedures. A few months later the turbo failed again out of warranty but this time cracked the head causing damages I can not afford!! The vehicle is sitting at the dealership not fixed!! I want out of this lemon!!! I tried getting them to buy it back when I took it to the shop three different times due to break issues they could not fix but a Ford representative told me it "had too many miles" I work out of this vehicle and have not been able to work now for three months!! Note...after the first TURBO was replaced I told the dealership the vehicle was loosing antifreeze but all they did was pressure check the radiator. A few months later engine failure due to turbo failure!!

The car caught fire the morning of Dec 11, 2024 while the vehicle's owner was driving their children to school. There are photos and a fire report is being generated. The vehicle's owner and her children could have been killed. Early indications are that the fire was caused by the same faulty engine/exhaust system defect that the owner has been complaining to Ford about for years. It is assumed the fire report will confirm that. For the past two or more years the vehicle has been emitting exhaust fumes into the passenger compartment of the vehicle while driving. This has caused the vehicle's owner and her children to get sick and forced them to drive the vehicle with the windows down at all times even in cold weather. Ford's dealers have confirmed the problem several times, but either could not or refused to fix it.

2RQ24014 · Loss Of Motive Power
Opened Nov 15, 2024 · Closed Oct 10, 2025
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery
On January 31, 2024, The Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24002) to investigate loss of motive power allegations in model year (MY) 2021 Ford Bronco Sport vehicles. Consumers reported a loss of engine power accompanied by complete electrical system failure either while driving or after stopping at a traffic light or stop sign. The vehicles generally could not be restarted, and the incidents were commonly diagnosed by dealerships to a failed 12-Volt (12V) battery. On April 12, 2024, Ford issued safety recall 24V-267 covering 456,565 MY 2021-2024 Ford Bronco Sport and MY 2022-2023 Ford Maverick vehicles. The recall addressed loss of motive power resulting from sudden degradation of the 12V battery during the drive cycle. The recall remedy consisted of software updates to the body control module and the powertrain control module. The updated software aimed to provide warning to consumers when the battery is failing and inhibit certain vehicle functions which can lead to loss of motive power incidents. Additionally, Ford removed the existing 12V Enhanced Flooded Battery (EFB) as both a service component for the subject vehicles and original equipment for newly built Bronco Sport vehicles (during MY 2024 production), replacing it with a more robust absorbed glass mat (AGM) battery. The same AGM battery had been incorporated into Ford Maverick production in late 2022. Following recall 24V-267, ODI received loss of motive power complaints in vehicles that had previously received Ford’s software-based remedy. Consumers reported that they did not receive warnings related to the 12V battery or the vehicle’s electrical system before the loss of power. On November 15, 2024, ODI opened Recall Query (RQ24014) to assess the effectiveness of the 24V-267 recall remedy. On January 19, 2025, Ford issued recall 25V-019 covering 272,817 MY 2021-2023 Bronco Sport and MY 2022-2023 Ford Maverick vehicles. The new recall addressed the same hazard as 24V-267 but required replacement of the existing 12V battery with an AGM battery as the remedy. Ford reported that following the opening of RQ24014, it evaluated several field-returned 12V batteries, and determined that EFBs produced by battery supplier Camel potentially contained internal manufacturing defects causing loss of motive power. Ford further concluded that the software updates provided in the 24V-267 recall remedy were unable to detect battery failures quickly enough to avoid loss of motive power. Vehicles previously within the scope of recall 24V-267, but outside of the scope of recall 25V-019, are equipped with EFBs produced by a different battery supplier (Clarios). When recall 25V-019 was issued, Ford had not identified any Clarios EFBs exhibiting the same failure mode as the Camel EFBs. In light of Ford’s recall action, ODI is closing this Recall Query. The agency will continue to monitor loss of motive power complaints in Bronco Sport vehicles equipped with Clarios EFBs and reserves the right to take additional action if warranted by future circumstances.

PE24002 · Loss Of Motive Power
Opened Jan 31, 2024 · Closed Aug 19, 2024
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery
On January 31, 2024, the Office of Defects Investigation (ODI) opened PE24002 to investigate allegations of loss of motive power in model year (MY) 2021 Ford Bronco Sport vehicles. At that time, ODI had received 31 Vehicle Owner Questionnaires (VOQs), with consumers commonly reporting a loss of engine power accompanied by complete electrical system failure which occurred either while driving, or after coming to a stop. The investigation revealed that MY 2021-2024 Ford Bronco Sport and certain MY 2022-2023 Ford Maverick vehicles are equipped with a 12V enhanced flooded battery (EFB), which may experience an abrupt failure during a drive cycle. The failure is the result of an internal corrosion issue, which is influenced by long exposure to high under-hood temperatures. If the sudden loss of 12V battery voltage is not detected by the vehicle’s battery management sensor, the vehicle can experience a loss of power event without providing any warning to the driver. Following a loss of power due to battery failure, the vehicle may be without all 12V accessories including hazard lights and typically will not be able to be restarted. In its March 2024 response to ODI’s information request, Ford provided 367 customer complaints (including field reports, lawsuits, and legal claims) and 1005 warranty claims relating to the alleged defect. When combining ODI and manufacturer failure report data, there are 1,368 unique VINs represented across MY 2021-2023 Ford Bronco Sport vehicles. One of the VOQs submitted to NHTSA reported a minor rear-end collision resulting from a loss of power event. Included within Ford’s complaints were a reported single-vehicle collision and a vehicle fire which occurred following a loss of power event at a traffic light (fire cause and origin was not determined). Additionally, across ODI and manufacturer data, there were 12 allegations of either acid leaking from the 12V battery or smoke emitting from the battery area within the engine compartment. On April 12, 2024, Ford submitted recall 24V267 for MY 2021-2024 Ford Bronco Sport and certain MY 2022-2023 Ford Maverick vehicles (total population 456,565). The recall remedy provides updated calibrations to the body control module and powertrain control module. Ford indicated that the update will result in improved detection of 12V battery state of charge during drive cycles and will provide notification to the driver if the battery significantly degrades while driving. Additionally, Ford has replaced the EFB with an absorbed glass mat (AGM) battery as both a service component for the subject vehicles and as original equipment for Bronco Sport vehicles with production dates beginning in mid-March 2024. The warranty claim rate for peer vehicles equipped with an AGM battery is substantially lower than that for the subject vehicle population. In view of the recall action being taken by Ford, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.
